Lead workers are getting sick; OSHA starts its rulemaking process
OSHA’s June 2022 Advance Notice of Proposed Rulemaking (ANPRM) sought employers’ comments about reducing workers’ blood lead levels and the ill-health effects of over-exposure. At the request of stakeholders, the Agency extended its comment period to October 2022. OSHA plans to continue its rulemaking efforts in 2023. Its primary areas of concern include:
- Removing workers from lead work through medical removal protection;
- Reducing the permissible exposure limit;
- Assessing the frequency of blood lead level testing; and
- Evaluating other protections such as housekeeping, hygiene, and training.
Lead exposure can threaten your workers if they perform abrasive blasting, sanding, scraping, cutting, burning, welding, and painting during repair, reconstruction, dismantling, and demolition work.
Medical data shows that America’s lead workers are getting sicker; OSHA’s ready to change its lead standards to protect workers. If they’re not adequately protected, their chances of exposing themselves to lead poisoning are high. This in-depth article focuses on housekeeping and hygiene protections — the two most accessible controls to measure and enhance!
How can it hurt your workers?
OSHA has been combing through medical data, concluding that overexposed lead workers may need to be removed from lead work duties sooner than its current standard requires. A short-term high-dose exposure could result in a brain disorder escalating to seizures, coma, or even death. Long-term exposure can decrease reaction time and cause nervous system damage, kidney disease, reproductive impairment, or death.
When absorbed into the body, lead is toxic in certain doses. Lead is absorbed by inhalation (breathing lead fumes, dust, or mist) and ingestion (eating). A few lead compounds can be absorbed through the skin.
OSHA limits the lead concentration in work area air to 50 micrograms per cubic meter for an 8-hour workday. This is the permissible exposure limit (PEL). OSHA may decide to lower the PEL in its final rule. Many stakeholders are concerned this would cause increased challenges in reducing exposure levels within containments by using mechanical ventilation and respiratory protection.
What must employers do?
Employers must determine whether or not OSHA’s action level for workers has been reached or exceeded when lead activities occur in the workplace. Workers must be notified when they are. Exposure levels are determined through personal and area sampling.
If exposure is above the PEL, your company must use control measures to keep the exposure level as low as possible. These controls can include using HEPA vacuums, distancing employees from abrasive blasting operations, using chemicals to remove lead-based paint instead of hand scraping, replacing lead-based painted building components, brushing/rolling paint instead of spraying, and substituting other coatings for lead-based coatings.
Remember, OSHA’s standard also provides for compliance plans, medical surveillance, training, and recordkeeping. While OSHA is going through its rulemaking process, if you have lead activities, ensure that worker protections are adequate. Here is subject matter expert guidance to ensure your workers are doing enough to protect themselves.
How can you protect your workers?
Use the following good work practices to protect your workers when working with lead:
- Communicate exposure levels. If exposure exceeds the PEL, post the following message: WARNING, LEAD WORK AREA, POISON, NO SMOKING OR EATING.
- Use protective clothing. Store street clothes separately from work clothes. Never wear contaminated clothes home.
- Use the correct, clean respirator. Respirators are used along with engineering controls and work practices. They are put on and removed outside the lead work area. Fit testing guarantees a tight seal.
- Keep the worksite clean. When removing lead dust, use only a vacuum with a HEPA filter or wet cleaning methods. Never use compressed air for cleaning.
- Wash hands and face areas before eating, drinking, smoking, or applying cosmetics.
- Eat, drink, or smoke outside the lead work area. Keep all lunch boxes and coffee cups away from the lead work area. Use a separate lunchroom.
- Shower and change into clean clothes, including shoes, before leaving the worksite so that no lead contamination is carried home.
OSHA is reviewing stakeholder comments about how these practices reduce workers’ exposure to lead effectively.
End-of-day procedures
Workers should follow these procedures when finishing work for the day:
- Place disposable coveralls and shoe covers in with the lead waste upon leaving the lead work area.
- Contain lead-contaminated clothes, including work boots and personal protective equipment for laundering/cleaning (by the employer), in a closed container in the changing area.
- Take a shower and wash their hair (or wash their face and hands if a shower isn’t available).
- Change into street clothes.
These ancillary protections probably will remain the same in OSHA’s updated lead standard. OSHA may add additional ones, though.
Key to remember
Lead exposure can threaten your workers if they perform abrasive blasting, sanding, scraping, cutting, burning, welding, and painting during repair, reconstruction, dismantling, and demolition work. If exposure is above the PEL, your company must use control measures to keep the exposure level as low as possible.
