Consumers' Risk Perception of Household Cleaning and Washing Products

Cultural uncertainty avoidance predicts consumers' affective reactions to chemicals

Chemicals in general often evoke negative emotions (e.g., worry or fear) in consumers. This can cause consumers to avoid beneficial products and may even lead to suboptimal public policy decisions. It is, therefore, important to better understand how affective reactions to chemicals in general (ARC) form in order to be able to counteract these undesirable effects. The present research contributes to the literature on ARC by studying between-country differences in ARC. While ARC were negative in all countries in our dataset, there were practically relevant between-country differences in how negative they were. We predicted and found that consumers in higher uncertainty avoidance (UA) societies reported more negative ARC than their counterparts in lower UA societies. This effect was due to the rule orientation component rather than the anxiety component of UA. Importantly, while we found evidence for several alternative explanations for between-country variation in ARC (i.e., differences in affluence, individualism, prevalence of chemicals, and trust in consumer protection), the UA effect remained statistically significant when we controlled for other country characteristics. The present research contributes to a better understanding of how contextual factors on the society level influence consumers' ARC and in doing so advances our understanding of ARC. It also has implications for practitioners who wish to educate consumers on the risks and benefits of chemicals.

Avoiding unintentional injuries from household chemicals: Comparing the appeal to children from the perspectives of children, caregivers, and experts

This study investigated whether caregivers and regulatory experts can predict the appeal of household chemicals for children and explored determinants of differences between adults' and children's child-appeal rating. We invited N = 95 4-year-old children and their caregivers to a laboratory study. Both independently ranked 16 household chemicals from the least to the most child-appealing product. In addition to the laboratory study, we sent an online adaptation of this ranking task to N = 46 experts involved in the monitoring and authorizing of household chemicals. Our findings show that the aggregated child-appeal rating of household chemicals was highly similar among caregivers, experts, and children. When comparing child-appeal ratings of household chemicals with and without child-appealing images, caregivers and experts did well in predicting which products might appeal to children. Finally, our findings show that the similarity between individual caregivers' and their own children's child-appeal ratings of household chemicals varied substantially. To conclude, although adults can assess the general child-appeal of household chemicals, they need to consider that the actual appeal of a household chemical can vary considerably among individual children. Instead of regulating specific product attributes, policymakers should prioritize educating caregivers about pitfalls and misconceptions that hinder effective injury prevention.

Protection motivation when using biocidal products - A survey study in Germany

Due to their inherent properties, biocidal products might pose a risk to human and animal health and the environment. In risk management, there exists uncertainty about private users' comprehension of and willingness-to-adhere to use instructions that mitigate these risks (e.g., limit frequency of use or application area). This study aimed at providing insights into the users' perspective by focusing on their attention, comprehension, and the attitudinal predictors of protection motivation. In the online study (N = 957 participants from Germany) were introduced to a hypothetical purchase scenario featuring an insect spray and a realistic set of use instructions. Next, the participants' attention for the use instruction was measured in self-report and by tracking the time spent on the page with the use instruction, while Likert scale-type questions measured the comprehensibility, protection motivation, and predictors. Participants reported higher protection motivation if they spent more time with the use instruction, perceived it as comprehensible, rated the threat to humans, animals, and the environment as more severe, perceived themselves as responsible (i.e., internal locus of control) and capable (i.e., self-efficacy) of adhering to the use instructions, perceived adherence to the use instructions as effective (i.e., response efficacy) and did not perceive biocidal products as inherently safe (i.e., neutral locus of control). These results offer valuable information for an improved regulation of biocidal products and better management of potential risks associated with their use. They also provide concepts for interventions to ensure users of biocidal products follow the instructions for a safe use and better protection of the environment.

Childhood poisonings: Effects of ambiguous product characteristics on preschool children's categorization of household chemicals

This study investigated preschool children's categorization and risk perception of products with ambiguous product characteristics (e.g., food-like packaging). These characteristics make it difficult for preschool children to categorize household chemicals correctly. This, therefore, increases the risk of unintentional poisoning. We hypothesized that ambiguity arises from different product characteristics, such as the type of packaging, the products' scent, or the packaging's color and transparency. In four behavioral tasks, N = 108 preschool children (M = 43 months, SD = 3) categorized different products and household chemicals with various types of packaging, colors, and scents. Individually wrapped dishwasher tablets were more likely to be categorized as edible than unwrapped ones. Furthermore, children who had interacted with any type of dishwasher tablet in the last 6 months performed better in identifying dishwasher tablets, regardless of packaging type. Household chemicals with a fruity scent were more likely to be categorized as drinkable than those with a chlorine scent. Finally, the children considered black bottles more dangerous and preferred them less than bottles of a different color. In contrast, bottle transparency generally did not seem to affect risk perception and preference. These findings confirm that ambiguous product characteristics influence children's categorization of unknown products and, thus, their risk perception and decision-making. Manufacturers and caregivers are advised to reduce the ambiguity of household chemicals by designing more neutral product packaging and choosing products with more neutral elements, respectively.

Does green mean clean? Volatile organic emissions from regular versus green cleaning products

Cleaning products emit a range of volatile organic compounds (VOCs), including some which are hazardous or can undergo chemical transformations to generate harmful secondary pollutants. In recent years, "green" cleaners have become increasingly popular, with an implicit assumption that these are better for our health and/or the environment. However, there is no strong evidence to suggest that they are better for indoor air quality compared to regular products. In this study, the VOC composition of 10 regular and 13 green cleaners was examined by headspace analysis. Monoterpenes were the most prevalent VOCs, with average total monoterpene concentrations of 8.6 and 25.0 mg L-1 for regular and green cleaners, respectively. Speciated monoterpene emissions were applied to a detailed chemical model to investigate the indoor air chemistry following a typical cleaning event. Green cleaners generally emitted more monoterpenes than regular cleaners, resulting in larger increases in harmful secondary pollutant concentrations following use, such as formaldehyde (up to 7%) and PAN species (up to 6%). However, emissions of the most reactive monoterpenes (α-terpinene, terpinolene and α-phellandrene), were observed more frequently from regular cleaners, resulting in a disproportionately large impact on the concentrations of radical species and secondary pollutants that were formed after cleaning occurred.

Biocidal products: Opportunities in risk assessment, management, and communication

In the coronavirus disease 2019 era, biocidal products are increasingly used for controlling harmful organisms, including microorganisms. However, assuring safety against adverse health effects is a critical issue from a public health standpoint. This study aimed to provide an overview of key aspects of risk assessment, management, and communication that ensure the safety of biocidal active ingredients and products. The inherent characteristics of biocidal products make them effective against pests and pathogens; however, they also possess potential toxicities. Therefore, public awareness regarding both the beneficial and potential adverse effects of biocidal products needs to be increased. Biocidal active ingredients and products are regulated under specific laws: the Federal Insecticide, Fungicide, and Rodenticide Act for the United States; the European Union (EU) Biocidal Products Regulation for the EU; and the Consumer Chemical Products and Biocide Safety Management Act for the Republic of Korea. Risk management also needs to consider the evidence of enhanced sensitivity to toxicities in individuals with chronic diseases, given the increased prevalence of these conditions in the population. This is particularly important for post-marketing safety assessments of biocidal products. Risk communication conveys information, including potential risks and risk-reduction measures, aimed at managing or controlling health or environmental risks. Taken together, the collaborative effort of stakeholders in risk assessment, management, and communication strategies is critical to ensuring the safety of biocidal products sold in the market as these strategies are constantly evolving.

Protecting the children -a virtual reality experiment on consumers' risk perceptions of household chemicals

Warnings on the labels of hazardous household chemicals (e.g. warning pictograms and use instructions) should create risk awareness and thus encourage safe storage, handling and disposal. However, scientific findings have called into question the effectiveness of warnings to prevent accidents, albeit mostly based on consumers' self-reports. This study aimed to contribute to existing data on household chemicals and consumer safety by applying a novel observational method using virtual reality (VR). The study participants (N = 119) were observed after receiving a task to childproof a virtual apartment from various interactable neutral and hazardous objects (i.e. knives, lighters and household chemicals with and without warnings) that were placed in the virtual apartment. For the analysis, the object placement (i.e. accessible or inaccessible to the children) and the level of interaction with the objects were coded, and the observational data were supplemented with data gathered through a questionnaire. The results showed that most hazardous household chemicals were moved to spots that were inaccessible to the children without any interactions of the participants with the warnings. Instead, they used their pre-existing knowledge and intuitive strategies to judge the objects' risks. These potentially misleading intuitive strategies should be increasingly considered in the regulation of hazardous household chemicals. This study also discussed the use and limitations of VR for the observation of human behaviour and decision making under uncertainty.

Seeing household chemicals through the eyes of children-Investigating influential factors of preschoolers' perception and behavior

INTRODUCTION

Children who encounter household chemicals run the risk of unintentional injury. The aim of this study was to understand which factors heighten children's attention or misguide their decision-making concerning household chemicals. We hypothesized that certain product attributes (i.e., label, packaging, closure types), storage context, and parental beliefs play a role in this setting.

METHOD

We conducted a laboratory study with N = 114 children (M = 45 months, SD = 6.5) and their parents (M = 38 years, SD = 4.92). Children completed a series of behavioral tasks in which they had to choose between products with different attributes, identify products in different storage contexts, and sort household chemicals.

RESULTS

The results confirmed that the children preferred products with cartoon-style labels compared to products without such labels. However, children's decision-making did not differ for products with different closure types (child-resistant vs sprayer-type closures). Regarding the storage context, our results showed that the children particularly struggled to identify dishwashing tabs when they were stored with other food items rather than household chemicals. In terms of parental beliefs, our study found that parents rated more household chemicals as child-safe than their children did.

PRACTICAL APPLICATION

Parents should buy household chemicals with neutral labels and pay attention to how their household chemicals are stored. Manufacturers should consider potential adverse effects when developing new product designs.

When information security depends on font size: how the saliency of warnings affects protection behavior

Prior research on how to improve the effectiveness of information security warnings has predominantly focused on either the informational content of warnings or their visual saliency. In an online experiment (N = 1'486), we disentangle the effect of both manipulations and demonstrate that both factors simultaneously influence decision making. Our data indicate that the proportion of people who engage in protection behavior can be increased by roughly 65% by making a particular warning message more visually salient (i.e. a more conspicuous visual design is used). We also show that varying the message's saliency can make people behave very differently when confronted with the same threat or behave very similarly when confronted with threats that differ widely in terms of severity of outcomes. Our results suggest that the visual design of a warning may warrant at least as much attention as the informational content that the warning message conveys.

Consumers' decision-making process when choosing potentially risky, frequently used chemical household products: The case of laundry detergents

Chemical household products are a common cause of accidents in the domestic sphere. Despite such products being associated with certain risks in the event of swallowing or contact with the skin or eyes, they are used in nearly every household worldwide for hygiene purposes. In most European countries, chemical household products feature warnings of the Globally Harmonized System (GHS) as well as other warnings. In this eye-tracking study (N = 147), which was conducted in a virtual environment, we examined (i) whether consumers use such warnings when choosing a laundry detergent, (ii) whether they consider information irrelevant to risk assessment and (iii) whether they make use of this information for their final product choice. For this, the participants were split randomly into three experimental groups (a risk priming group, an effectiveness priming group, and a control group) that each received different tasks while purchasing a laundry detergent. The results indicate that the warnings found on laundry detergents are effective when they are used, although the majority of consumers do not look at the warnings. Therefore, we suggest that the alternative placement of warnings or the use of simplified warnings should be considered to improve consumers' awareness of potential risks.

The influence of packaging on consumers' risk perception of chemical household products

Chemical household products are found in most households. If consumers are to safely handle such products, they need to be aware of the risks posed by the particular product they are using. Although most countries require that chemical household products feature warning labels (e.g. the Globally Harmonized System of Classification and Labelling of Chemicals), consumers appear to also use other cues to determine the risks associated with a specific product. Thus, we studied the influence of packaging on consumers' risk perception of chemical household products. More specifically, we examined the effect of the colour of the packaging (black or pink packaging versus the original packaging) as well as the presence of images of flowers or food-imitating elements on the packaging. Significant differences with regard to consumer's risk perception were found in terms of all four studied manipulations. Therefore, we conclude that consumers' risk perception can be influenced by the packaging design. In particular, if elements that lower consumer's risk perception (e.g. featuring flowers on the label and food-imitating elements on the packaging) are omitted from the packaging, consumers might be able to more accurately judge the risks associated with a product and so take appropriate safety precautions.

A Study on the Behavior Patterns of Liquid Aerosols Using Disinfectant Chloromethylisothiazolinone/Methylisothiazolinone Solution

This study evaluates the behavioral characteristics of components (methylisothiazolinone (MIT) and chloromethylisothiazolinone (CMIT)) contained in disinfectant solutions when they convert to liquid aerosols. The analytical method for MIT and CMIT quantitation was established and optimized using sorbent tube/thermal desorber-gas chromatography-mass spectrometry system; their behavioral characteristics are discussed using the quantitative results of these aerosols under different liquid aerosol generation conditions. MIT and CMIT showed different behavioral characteristics depending on the aerosol mass concentration and sampling time (sampling volume). When the disinfectant solution was initially aerosolized, MIT and CMIT were primarily collected on glass filter (MIT = 91.8 ± 10.6% and CMIT = 90.6 ± 5.18%), although when the generation and filter sampling volumes of the aerosols increased to 30 L, the relative proportions collected on the filter decreased (MIT = 79.0 ± 12.0% and CMIT = 39.7 ± 8.35%). Although MIT and CMIT had relatively high vapor pressure, in liquid aerosolized state, they primarily accumulated on the filter and exhibited particulate behavior. Their relative proportions in the aerosol were different from those in disinfectant solution. In the aerosol with mass concentration of ≤5 mg m^-3, the relative proportion deviations of MIT and CMIT were large; when the mass concentration of the aerosol increased, their relative proportions constantly converged at a lower level than those in the disinfectant solution. Hence, it can be concluded that the behavioral characteristics and relative proportions need to be considered to perform the quantitative analysis of the liquid aerosols and evaluate various toxic effects using the quantitative data.

The exploration of size and toddler interaction with liquid laundry detergent capsules

Liquid laundry capsules have been involved in multiple poisoning incidents with young children in the home. There are a range of contributing factors for these incidents, including influences from industry, culture, home environments, and parenting/supervision. There also are influences from children’s behaviour and decisions in reaction to potential hazards. Previous research examined the influence of capsule product appearance and colour on children’s behaviour around hazardous household items, but little research examines the influence of product size. This research explored if differences in the size of liquid laundry capsules result in different levels of toddler interaction. We compared two commercially available capsule designs that are identical in physical appearance but differ in physical size. Our research was conducted using three studies: Study 1, forced-choice test in an out-of-context laboratory setting; Study 2, an ecologically-valid, simulated real-world setting replicating a home laundry cabinet with a container of capsules left open; and Study 3, a second ecologically-valid study replicating a home laundry cabinet, this time with a capsule left outside its container. Capsule interaction was measured by grasping choice among samples of 156 toddlers ages 9–36 months. The same sample was used for Studies 1 and 2, and a second identically sized sample recruited for Study 3. Results from Study 1 indicated toddlers selected the small (49.8% selection) and large (50.2%) capsule with nearly identical frequency. Study 2 largely replicated Study 1: Toddlers selected the small capsule or container of small capsules 26.8% of the time and the large capsule or container of large capsules 22.3% of the time. Study 3 also replicated previous findings: Toddlers selected the smaller capsule 18.0% of the time and the larger 19.2%. We discuss study results, which suggest no appreciable difference in toddler’s grasping choice to smaller versus larger laundry capsules.

Safe Use and Storage of Cleaners, Disinfectants, and Hand Sanitizers: Knowledge, Attitudes, and Practices among U.S. Adults during the COVID-19 Pandemic, May 2020

Cleaning and disinfection of frequently touched surfaces and frequent hand hygiene are recommended measures to prevent transmission of SARS-CoV-2, the virus that causes COVID-19. Since the onset of the COVID-19 pandemic, poison center calls regarding exposures to cleaners, disinfectants, and hand sanitizers have increased as compared with prior years, indicating a need to evaluate household safety precautions. An opt-in Internet panel survey of 502 U.S. adults was conducted in May 2020. Survey items evaluated knowledge regarding use and storage of cleaners, disinfectants, and hand sanitizers; attitudes about household cleaning and disinfection; and safety precautions practiced during the prior month. We assigned a knowledge score to each respondent to quantify knowledge of safety precautions and calculated median scores by demographic characteristics and attitudes. We identified gaps in knowledge regarding safe use and storage of cleaners, disinfectants, and hand sanitizers; the overall median knowledge score was 5.17 (95% CI: 4.85-5.50; maximum 9.00). Knowledge scores were lower among younger than older age-groups and among black non-Hispanic and Hispanic respondents compared with white non-Hispanic respondents. A greater proportion of respondents expressed knowledge of safety precautions than the proportion who engaged in these precautions. Tailored communication strategies should be used to reach populations with lower knowledge of cleaning and disinfection safety. In addition, as knowledge alone did not shape individual engagement in safety precautions, health promotion campaigns may specifically emphasize the health risks of unsafe use and storage of cleaners, disinfectants, and hand sanitizers to address risk perception.

Risk Perception: Reflections on 40 Years of Research

Numerous studies and practical experiences with risk have demonstrated the importance of risk perceptions for people's behavior. In this narrative review, we describe and reflect upon some of the lines of research that we feel have been important in helping us understand the factors and processes that shape people's risk perceptions. In our review, we propose that much of the research on risk perceptions to date can be grouped according to three dominant perspectives and, thus, approaches to study design; they are: the characteristics of hazards, the characteristics of risk perceivers, and the application of heuristics to inform risk judgments. In making these distinctions, we also highlight what we see as outstanding challenges for researchers and practitioners. We also highlight a few new research questions that we feel warrant attention.

Consumers' perceptions of chemical household products and the associated risks

Accidents with chemical household products are prevalent worldwide and often involve young children. Previous research has shown that consumers use both analytical factors (e.g., warning symbols) and potentially misleading heuristics to evaluate the riskiness. However, it remains unclear whether consumers intuitively think of the specific risks of these products when handling them. We conducted an online survey with Swiss consumers (N = 1109) aiming to investigate consumer's spontaneous and prompted risk perception of chemical household products. First, we asked them about their free associations to laundry detergent, descaler, mold remover and essential oils. While participants were aware of the risks when prompted about them, they did not name them intuitively, but mainly thought of the possible uses and attributes of the product. Next, we examined prerequisites to safe handling of chemical household products. This included applied knowledge about the products, but also factors like perceived barriers to safe use. Finally, we assessed the predictors of perceived severity of accidents in order to estimate the potential behavioral changes that these predictors might elicit. For interventions, particular attention should be accorded to personal risk awareness and the perception of potential barriers, which were significantly related to the perceived severity of accidents.

Social Influence, Risk and Benefit Perceptions, and the Acceptability of Risky Energy Technologies: An Explanatory Model of Nuclear Power Versus Shale Gas

Risky energy technologies are often controversial and debates around them are polarized; in such debates public acceptability is key. Research on public acceptability has emphasized the importance of intrapersonal factors but has largely neglected the influence of interpersonal factors. In an online survey (N = 948) with a representative sample of the United Kingdom, we therefore integrate interpersonal factors (i.e., social influence as measured by social networks) with two risky energy technologies that differ in familiarity (nuclear power vs. shale gas) to examine how these factors explain risk and benefit perceptions and public acceptability. Findings show that benefit perceptions are key in explaining acceptability judgments. However, risk perceptions are more important when people are less familiar with the energy technology. Social network factors affect perceived risks and benefits associated with risky energy technology, hereby indirectly helping to form one's acceptability judgment toward the technology. This effect seems to be present regardless of the perceived familiarity with the energy technology. By integrating interpersonal with intrapersonal factors in an explanatory model, we show how the current "risk-benefit acceptability" model used in risk research can be further developed to advance the current understanding of acceptability formation.

Addressing Chemophobia: Informational versus affect-based approaches

This study investigated the effect of two communication strategies (informational and affect-based) in reducing chemophobia, the irrational fear of chemicals. In an online experiment, participants (N = 448) were randomly assigned to one of three groups ("control", "knowledge", or "affect" group). The following dependent variables were assessed: chemophobia, knowledge of basic toxicological principles, affect towards chemicals, benefit perception of the use of chemicals, and preference for natural substitutes in consumer products. The results showed that only the informational approach, which conveys knowledge of basic toxicological principles, significantly decreased chemophobia and the preference for natural substitutes in consumer products. The affect-based approach significantly increased positive affect towards chemicals and the benefit perception of their use, but did not decrease chemophobia. This suggested that the provision of relevant information about basic toxicological principles is a more effective strategy than merely addressing laypeople's affect towards chemicals to reduce chemophobia. Relevant knowledge could be taught in schools or disseminated by toxicologists and scientists who are trusted by the public.

Barriers to the safe use of chemical household products: A comparison across European countries

Chemical household products, such as cleaning and washing products or pest control and garden chemicals, are frequently involved in poisonings in private households. Consumer research has identified a number of barriers that impede the safe use of these products, ranging from unfamiliarity, to misconceptions and a lack of risk perception, to behavioural or situational barriers. This study aimed at investigating these barriers for consumers in eight European countries. Participants from eight European countries were recruited and asked to fill out an online questionnaire on their familiarity with hazard pictograms, perceptions and self-reported behaviour (Total: N = 5631, Austria: N = 731, Switzerland: N = 698, Germany: N = 711, France: N = 708, Italy: N = 695, Poland: N = 693, Sweden: N = 682, UK: N = 713). Across all countries, the lowest consumer familiarity was found for the meaning of the pictogram for "health hazard" (65% indicated having never seen it before). Small-sized differences between the eight countries were observed regarding people's familiarity, perceptions and self-reported behaviour. The results suggest that people apply hazard-related as well as product- and marketing-related strategies to judge the dangerousness of a chemical household product. These findings suggest a number of starting points for risk regulation and communication regarding hazardous household chemical products. Further, the results suggest that positive outcome expectancies and rules of thumb for judging the risks of a chemical household product are particularly relevant for people's self-reported safe use of chemical household products.

"Chemophobia" Today: Consumers' Knowledge and Perceptions of Chemicals

This mixed-methods study investigated consumers' knowledge of chemicals in terms of basic principles of toxicology and then related this knowledge, in addition to other factors, to their fear of chemical substances (i.e., chemophobia). Both qualitative interviews and a large-scale online survey were conducted in the German-speaking part of Switzerland. A Mokken scale was developed to measure laypeople's toxicological knowledge. The results indicate that most laypeople are unaware of the similarities between natural and synthetic chemicals in terms of certain toxicological principles. Furthermore, their associations with the term "chemical substances" and the self-reported affect prompted by these associations are mostly negative. The results also suggest that knowledge of basic principles of toxicology, self-reported affect evoked by the term "chemical substances," risk-benefit perceptions concerning synthetic chemicals, and trust in regulation processes are all negatively associated with chemophobia, while general health concerns are positively related to chemophobia. Thus, to enhance informed consumer decisionmaking, it might be necessary to tackle the stigmatization of the term "chemical substances" as well as address and clarify prevalent misconceptions.

[Carbon monoxide-an underestimated risk? Awareness, perception, knowledge, and prevention activities]

BACKGROUND

Every year, hospitals in Germany treat roughly 450,000 people in the aftermath of poisoning incidents. To reduce the number of poisoning accidents, it is essential to inform the public about poisoning risks and the possibilities for prevention.

OBJECTIVES

The goal was to examine risk perception of poisonings in order to derive insights into adequate communication activities from the results. As a special focus topic, the risk of carbon monoxide poisoning was chosen.

METHOD

Telephone interviews were conducted with 1,012 persons aged 14 or over in Germany. They were asked about their awareness, perception, and knowledge of poisoning risks, particularly carbon monoxide.

RESULTS

Most people are aware of risks such as accidental intoxications caused by alcohol, carbon monoxide, or mushrooms. Other risks that could be especially dangerous for children, like coin cell batteries, lamp oils, or liquids in e‑cigarettes, are less known. Of the interviewees, 82% had already heard of poisoning incidents in connection to carbon monoxide and 41% estimated the risk of accidental carbon monoxide poisoning as rather or very high. However, only 15% had already installed a carbon monoxide detector. Although people are mostly aware of the main causes and identifiers of carbon monoxide poisoning, more than one third still believe that carbon monoxide can be identified by its odor, smoke, or the smoke alarm signal. In addition, there is a special need for information about the risks of carbon monoxide intoxication through indoor shisha smoking and indoor storage of wood pellets.

CONCLUSION

The results offer first insights into the target groups and possible dissemination paths for future risk communication activities.

Risk Prioritization in the Food Domain Using Deliberative and Survey Methods: Differences between Experts and Laypeople

This study examined how experts and laypeople using both a deliberative and a survey method prioritized 28 hazards related to food and everyday items. To enable them to make deliberative decisions, participants received detailed descriptions of the hazards. The participants prioritized the hazards before and after a group discussion, in which the group's average prioritization was discussed. The rankings of the hazards before and after the group discussion were highly correlated. However, laypeople and experts differed significantly in their rankings for 18 of the 28 hazards. Trust and confidence were important predictors for laypeople's risk rankings. To test the influence of the deliberative method (e.g., providing detailed information about each hazard), data from a second group of laypeople were collected with a no-information survey. This group did not receive specific information about the hazards. The risk rankings of the laypeople who received information were highly correlated with the risk rankings of laypeople who did not receive information. Overall, the results suggest that deliberative methods of risk-ranking or no-information survey methods with no information about hazards provide similar results among laypeople. The conclusion is that government agencies should not only base their risk prioritization on evidence from risk assessments but also need to consider laypeople's hazard rankings. This procedure may result in an efficient and publicly accepted risk management strategy.

Practices in Using and Handling Household Cleaning Products in Egypt

The objective of this study is to investigate woman's practices and perceptions of using and handling of household cleaning products using qualitative and ergonomics methodology developed to reveal skills in daily life activities. A checklist and an open ended questionnaire were used in which the participants were observed and asked about the frequency of performing cleaning tasks, average monthly consumption of detergent, strategies employed for mixing products, various habits employed in cleaning, storage practices, strategies for personal protection and sharing the cleaning activities with family members. A non-probability sample of 228 volunteers, who were housewives, both employed and non-employed, with different levels of education were recruited for this study. Data were analyzed using SPSS software program. Results showed that children also contributed in domestic chores exposing themselves to chemicals. Women stated that they mixed different detergents together and over-consumed detergents. Contrasting results between the employed and non-employed women were found to be the duration of cleaning, the quantity of consumed laundry detergent and the measures of precautions and safety. The participants were consistently exposed to chemical detergents and minimal precautionary measures were taken. Cleanliness and hygiene have strong cultural values to women who prioritized those values over excessive exposure to chemicals.
