Safety and health risk perceptions: A cross-sectional study of New Jersey hair and nail salon clients

Newer New Jersey work-based learning teachers during the COVID-19 pandemic: school safety regarding ventilation, trainings, and awareness of government agencies resources

New Jersey (NJ) Safe Schools Program (NJSS) provides code-required trainings for NJ teachers supervising students in work-based learning (WBL) experiences. During the COVID-19 pandemic, increased use of chemical cleaning, sanitization, and disinfectant products (CSDPs) led to ventilation and other health concerns. NJSS conducted two surveys of newer NJ WBL teachers between October 2021 and June 2023, with a follow-up in fall 2022 for those who completed initial surveys before summer 2022. This study focused on questions regarding workspace ventilation; respirator and CSDPs trainings; awareness of government resources for safety and health (S&H); and demographics. Over 65% of participant classrooms have operable windows or ventilation systems, while 13% of school salons have ceiling fans. Half of participants didn't receive training on handling CSDPs, although 90% were aware of government S&H resources. Data suggested teachers have well-ventilated workspaces and are aware of different resources available, which is important to continue post COVID-19.

Perspectives and Attitudes of Newer New Jersey High School Teachers towards Cleaning, Sanitizing, and Disinfecting Consumer Products Used in School Classrooms

During the COVID-19 pandemic, there was an increased reported use of chemical cleaning, sanitizing, and disinfecting products (CSDPs), which created public concerns about negative health consequences for both children and adults in public schools. A subset of newer teachers shared experiences regarding safety and health (S&H) while working in school-based settings through a series of online surveys. Surveys were provided to teachers who completed work-based learning supervisory trainings provided by the New Jersey Safe Schools Program between October 2021 and June 2023. The participants answered questions focusing on CSDPs purchased for school use, their attitudes towards CSDPs, their use of personal protective equipment, and symptoms employees may have had due to CSDPs. A total of 205 teacher participants successfully completed the surveys. Over 25% of the teachers did not know where their CSDPs originated from, as they were provided by the school. Most participants "sometimes", "not often", or "never" read labels for CSDP ingredients or looked them up on healthy product apps. The participants (60%) tended to wear gloves while cleaning/disinfecting but did not wear masks. A third of the participants experienced respiratory health problems after working at school. Overall, the data suggest that more education on S&H regarding CSDPs needs to be provided to New Jersey teachers.

Occupational exposure to VOCs and carbonyl compounds in beauty salons and health risks associated with it in South Korea

Long-term exposure to volatile organic compounds (VOCs) and carbonyl compounds in beauty products may adversely impact the health of beauty salon technicians. Previous studies have focused on assessing indoor air concentrations of chemicals, such as benzene and toluene, and not on personal exposure concentrations. This study measured the indoor and personal exposure concentrations of VOCs and carbonyl compounds in fifty-three beauty salons in Korea. Non-carcinogenic and carcinogenic risks and sensitivity were analyzed using the Monte Carlo simulation technique. The indoor and personal exposure concentrations of acetone were 82.24 µg/m³ and 104.97 µg/m³, respectively, the highest among all measured chemicals. Beauty salon technicians who experienced adverse health effects had significantly higher concentrations of acetone, benzaldehyde, and toluene than those who did not experience adverse health effects (p-value < 0.05). The average hazard quotients of formaldehyde and acetaldehyde were higher than the acceptable risk level (1), and the average cancer risks of formaldehyde exceeded the acceptable risk level (10^-6). Wearing personal protective equipment was the most efficient risk reduction strategy for reducing the non-cancer risks of acetaldehyde and formaldehyde and the carcinogenic risks of formaldehyde. The results of this study can be used as a basis for reducing exposure to VOCs and carbonyl compounds among salon technicians.

Gas-phase and PM2.5-bound phthalates in nail salons: characteristics, exposure via inhalation, and influencing factors

This study aimed to investigate the characteristics of, exposure to, and factors influencing gas-phase and PM_2.5-bound phthalates (PAEs) in nail salons. Data on both indoor and outdoor gas-phase and PM_2.5-bound PAEs, carbon dioxide (CO₂), temperature, and relative humidity were collected in nail salons. We also used questionnaires to survey building characteristics and occupants' behaviors. The average total gas-phase and PM_2.5-bound PAE concentrations indoors were higher than those outdoors by 6 and 3 times, respectively. Diethyl phthalate, diisobutyl phthalate (DiBP), di-n-butyl phthalate (DnBP), and di-(2-ethylhexyl) phthalate (DEHP) were the predominant compounds among both the gas-phase and PM_2.5-bound PAEs in indoor air. The volume of the salon's space or the difference of indoor and outdoor CO₂ concentrations (dCO₂) was significantly associated with indoor PAE concentrations. The ratios of PM_2.5-bound to gas-phase PAEs, especially high-molecular-weight PAEs, were positively associated with the dCO₂ concentrations. Higher ratios of indoor to outdoor PM_2.5-bound DiBP, DnBP, and DEHP concentrations were discovered when more clients visited each day. Building characteristics, ventilation conditions, and occupants' activities have influences on the gas-phase and particle-phase PAEs. The study identifies the characteristics of gas-phase and PM_2.5-bound PAEs in nail salons and their influencing factors.

Determinants of Exposures to Hazardous Materials among Nail Cosmeticians in the Kampala City, Uganda

Globally, nail salons represent a fast expanding industry and often with low-income cosmeticians. In general, cosmeticians have limited access to safety information about the hazardous materials they handle, which would potentially enable them to minimize workplace exposures. The problem is much pronounced in low- and middle-income countries due to weaknesses in regulation of the industry. We investigated determinants of exposures to hazardous materials among nail cosmeticians in Kampala District, Uganda. We employed a cross-sectional study design among a random sample of 243 participants. The sociodemographic characteristics, education and training status, knowledge about routes of exposure to hazardous chemicals, and personal protective material use of cosmeticians were assessed through face-to-face interviews. Most cosmeticians were aged 18–34 years, and more males were engaged in this work than females. Also, 82.7% believed inhalation was the major exposure route for the chemicals they handled. Participants who had attained secondary-level education and above were over three times more likely to wear masks (AOR = 3.19, 95% CI 1.58–6.41) and gloves (AOR = 3.48, 95% CI 1.55–7.81) and over two times more likely to use aprons (AOR = 2.50, 95% CI 1.18–5.32). Participants who had ever received safety training on hazardous chemicals were more likely to wear all four personal protective equipment: masks (AOR = 3.21, 95% CI 1.61–6.42), gloves (AOR = 4.23, 95% CI 2.05–8.75), goggles (AOR = 4.14, 95% CI 1.25–13.65), and aprons (AOR = 2.73, 95% CI 1.25–5.96). Participants who had spent more than two years in the nail cosmetics business were more likely to wear masks (AOR = 3.37, 95% CI 1.64–6.95). With the increasing demand for nail cosmetics, and many people in urban areas of low-income countries engaging in this industry, there is need for training and better workplace policies to promote a healthier urban workforce dealing in cosmetics.
