PAPR Pre-Filters after a single shift of filtering welding fumes

Filters this discolored after a single shift forces us to imagine what a welder's lungs could go through over a career without proper respiratory protection

Every once in awhile, a photo stops us in our tracks and makes us take stock. Here's one that was an eye opener for the owner of a welding operation in Michigan focused on aluminum and stainless steel welding.

  1. The shop traditionally provided welders with fit-tested half-face mask respirators, but decided to try 5 of the RPB Z4 air supplied respirator helmets with PX4 Powered Air Purifying Respirator (PAPR) to test them out
  2. After a full day of use, the shop manager decided to take a closer look at the filters and took these pictures
  3. Upon seeing them:
    1. The other employees were visibly concerned and the language used to express their concern was colorful
    2. The owner immediately put in an order for 7 more Z4 respirators, ensuring all workers have access to them when needed
  4. The International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) has classified welding fumes and UV radiation from welding as Group 1 carcinogens, the agency’s designation for agents that carry sufficient evidence of carcinogenicity in humans. - American Industrial Hygiene Association (AIHA)
  5. These Air Supplied Respirators for Welding from RPB provide respiratory and optical protection for welders, while giving them the freedom to work in compliance without time consuming fit-testing. Give us a call at (248) 221-8076 to talk about your respiratory protection needs.
