(Revised 06/20/2012) CSH Fact Sheet - #035

When employee exposures are at, or in excess, of the action level, but less than the eight-hour Permissible Exposure Limit (PEL) of 50ug/m3; the employer is required to implement routine air monitoring, medical surveillance, housekeeping, and training. Exposures in excess of the PEL require similar actions by the employer including, routine air monitoring, methods of complying with the PEL, the use of respiratory protection, the use of protective work clothing and equipment, housekeeping practices, hygiene facilities (i.e.

change areas, shower and hand washing facilities, and eating facilities), implementation of engineering and work practice controls through the development of a written compliance program, medical surveillance and medical removal protection, employee information and training, warning signs, and record keeping.

How to Avoid Hazards

The best way to prevent over-exposures to lead is to install and maintain engineering controls to eliminate or reduce the hazard. When employees are exposed above the PEL, the employer must develop a compliance program that includes engineering and work practice controls such as the following:

Conduct bulk material analysis to determine if lead is present.

Provide interim protection until air monitoring determines exposure levels.

Use exhaust ventilation and dust collection systems. For example, power tools used for grinding surfaces coated with lead containing paint can be equipped with dust collection systems. Use local exhaust ventilation where feasible.

Use wet methods or a vacuum equipped with a high efficiency particulate (HEPA) filter to clean work areas contaminated with lead materials. Do not dry sweep or use compressed air.

Comply with all requirements of Part 603 with regard to air monitoring, compliance program, use of protective work clothing and equipment, housekeeping, hygiene facilities, medical surveillance and medical removal protection, employee information and training, warning signs, and record keeping.

When engineering and work practice controls cannot be used or do not reduce exposure to an acceptable level, then the employer must provide respiratory protection. The type of respiratory protection required is based on the level of exposure determined by air monitoring. At a minimum, the respirator must be a half mask, air-purifying respirator with HEPA filters. Remember, the employer must then implement a respiratory protection program as required by MIOSHA Part 451, Respiratory Protection.

If respirators are used to protect employees, then a regulated area should be established to prevent unprotected employees from entering the exposure area.
