Maintaining or Moving Contaminated Equipment
Potential Source of Exposure:
  • Maintenance shop personnel may be exposed to lead dust when servicing and handling equipment that is contaminated with lead.
Possible Engineering & Work Practice Controls:
  • Decontaminate equipment prior to servicing by vacuum, water spray, or mechanical removal such as scraping or brushing in conjunction with local exhaust ventilation.
 


Shops
Potential Source of Exposure:
Maintenance Shop
Fig. 1. Maintenance shop
  • Exposure to lead may occur when working on contaminated equipment in the maintenance shop (Fig. 1).
Possible Engineering & Work Practice Controls:
  • Provide exhaust ventilated work areas or portable local exhaust ventilation.

  • Provide wash-up sink for employees in the shop.

  • Keep surfaces as free as practicable of lead contamination.

  • Ensure that all shop vacuums are equipped with HEPA filters capable of removing lead.

  • Empty vacuums in a manner that minimizes the reentry of lead into the shop.
