The Collision Auto Repair Safety Study (CARSS): a health and safety intervention

Preventive health measures in small and medium-sized enterprises: A scoping review on implementation strategies

OBJECTIVE

To describe implementation strategies for preventive health measures in SMEs and the effectiveness of the strategies on implementation outcomes.

METHODS

A literature search was performed in multiple electronic databases. Studies published between 2000 and 2021 that evaluated the implementation of preventive health measures in SMEs were included. Classification of implementation strategies was based on two complementary classification systems.

RESULTS

Nineteen studies, of which 5 RCTs were included. Eighteen distinct implementation strategies were reported. All studies applied a combination of implementation strategies, and nearly all reported a positive effect on one or more implementation outcomes: sustainability, acceptability, feasibility, penetration, fidelity, adoption, and appropriateness.

CONCLUSIONS

Overall, a positive effect of combined implementation strategies on the implementation outcome(s) was found. The 'distribution of educational materials' and 'provide ongoing consultation' combined show positive effects on sustainability.

A National Survey of Health and Safety Knowledge and Beliefs Among Technical Vocational Faculty in Autobody Collision Repair Technology

OBJECTIVES

Career technical education (CTE) programs prepare new generations of technicians in a variety of trades. Even though occupational safety and health (OSH) ought to be included as an essential part of CTE curricula it is frequently absent or inadequately taught.

METHODS

OSH knowledge and beliefs were assessed in a national sample of 125 secondary and post-secondary faculty in autobody collision repair technology.

RESULTS

Over 50% of faculty thought at least 75% of OSH knowledge was learned at school, and 9% felt that safety was primarily learned on the job. Knowledge scores ranged from 22% to 78%. Overall knowledge scores were significantly lower high school than post-secondary instructors (42% vs 50%, P ≤ 0.001) and in two categories: hazard recognition (44% vs 54%, P ≤ 0.05) and hazard control and shop equipment (30% vs 37%, P ≤ 0.05).

CONCLUSIONS

There are substantial gaps in OSH knowledge among secondary and post-secondary CTE instructors. CTE programs should address these gaps by providing trade-specific safety and health education to their instructors upon hiring.

Improving the knowledge and behavior of workplace chemical exposures in Vietnamese-American nail salon workers: a randomized controlled trial

OBJECTIVES

We assessed the efficacy of trainings with Vietnamese nail salon owners and workers on knowledge and behaviors that could reduce exposures to toxic chemicals in nail products.

METHODS

We trained Vietnamese salon owners in California (n = 77) who then trained their workers (n = 200) on best practices. In a cluster randomized controlled trial, we assessed the efficacy of the training on change in knowledge and self-reported behaviors. Data were collected from 2013 to 2016 and analyzed from 2016 to 2017.

RESULTS

Compared to the control group, the intervention group had significantly greater increases in knowledge about: safer nail polishes [odds ratio (OR) 3.7 (95% confidence interval (CI) 1.9, 7.2)]; proper ventilation methods (OR 4.2; 95% CI 2.2, 8.1); recommended glove types (OR 3.4; 95% CI 1.9, 6.3); and recommended product handling and storage (OR 4.1; 95% CI 1.7, 9.9). The intervention also increased best practices: using safer nail polishes (OR 3.6; 95% CI 1.9, 6.8); reading product labels (OR 2.6; 95% CI 1.3, 5.0); and wearing long sleeves (OR 2.4; 95% CI 1.3, 4.2).

CONCLUSIONS

The owner-to-worker intervention with culturally and linguistically appropriate training for salon owners who then trained workers was effective in promoting knowledge and self-reported behaviors that can reduce workplace chemical exposures.

Analysis of Workplace Accidents in Automotive Repair Workshops in Spain

Background

To analyze the effects of the factors associated with different types of injury (superficial wounds, dislocations and sprains, bone fractures, concussion and internal injuries, burns scalding and freezing) caused by occupational accidents in automotive repair workshops.

Methods

Study of a sample consisting of 89,954 industry accidents reported from 2003 to 2008. Odds ratios were calculated with a 95% confidence interval.

Results

Belonging to a small company is a risk factor for suffering three of the five types of injury studied. Women are less likely to suffer burns and superficial wounds, and more likely to suffer dislocations or sprains. Foreign workers are more likely to suffer concussion and internal injuries.

Conclusion

Health and safety strategies and accident prevention measures should be individualized and adapted to the type of worker most likely to be injured in each type of accident. Occupational health and safety training courses designed according to worker profile, and improving the participation of the workers in small firms creating regional or roving safety representatives would improve working conditions.

Two-year follow-up of the Collision Auto Repair Safety Study (CARSS)

This paper presents an evaluation of the sustainability of health and safety improvements in small auto collision shops 1 year after the implementation of a year-long targeted intervention. During the first year (active phase), owners received quarterly phone calls, written reminders, safety newsletters, and access to online services and in-person assistance with creating safety programs and respirator fit testing. During the second year (passive phase), owners received up to three postcard reminders regarding the availability of free health and safety resources. Forty-five shops received an evaluation at baseline and at the end of the first year (Y1). Of these, 33 were evaluated at the end of the second year (Y2), using the same 92-item assessment tool. At Y1, investigators found that between 70 and 81% of the evaluated items were adequate in each business (mean = 73% items, SD = 11%). At Y2, between 63 and 89% of items were deemed adequate (mean = 73% items, SD = 9.5%). Three safety areas demonstrated statistically significant (P < 0.05) changes: compressed gasses (8% improvement), personal protective equipment (7% improvement), and respiratory protection (6% decline). The number of postcard reminders sent to each business did not affect the degree to which shops maintained safety improvements made during the first year of the intervention. However, businesses that received more postcards were more likely to request assistance services than those receiving fewer.
