Summary
This study demonstrates that involving pathology lab workers in formaldehyde (FA) risk management, alongside environmental improvements, significantly reduces FA exposure below occupational limits. This strategy is key to ensuring healthier workplaces.
Area of Science:
- Occupational Health
- Environmental Science
- Laboratory Safety
Background:
- Formaldehyde (FA) exposure in pathology laboratories poses significant short- and long-term health risks to healthcare workers globally.
- Concerns exist regarding the safety and health of personnel working in environments with potential FA exposure.
Purpose of the Study:
- To implement and evaluate a strategy for minimizing formaldehyde exposure in a hospital pathology laboratory.
- The strategy focused on improving the working environment and engaging the workforce in risk management.
Main Methods:
- Utilized the NIOSH 2016 method for detecting gaseous formaldehyde.
- Conducted personal and area active sampling of FA, analyzed via High-Performance Liquid Chromatography.
- Measured FA exposure levels before and after implementing improvement interventions.
Main Results:
- Pre-intervention FA levels exceeded ACGIH Threshold Limit Values (TLV-TWA and TLV-STEL).
- Post-intervention median FA concentrations were 0.025 ppm (personal) and 0.023 ppm (area).
- These post-intervention levels were significantly lower than pre-intervention levels (p < 0.05) and below established ACGIH TLVs.
Conclusions:
- Worker involvement in risk management, combined with engineering improvements, effectively minimized formaldehyde pollution in the laboratory.
- Healthcare organizations should prioritize worker participation in managing occupational hazards like FA to achieve healthier workplaces.
