Ozone removal capability of a welding fume respirator containing activated charcoal / Alan R. Johnston, James F. Dyrud and Young Tzung Shih
Sumario: Development of air purifying respirators for protection against ozone has been slowed by concerns about oxidation of charcoal and other available sorbents. The suitability of a charcoal sorbent for low concentrations of ozone was evaluated as a part of the development of a half-mask air purifying respirator designed for welding fumes and ozone. Testing of the respirator confirmed that charcoal can be a suitable sorbent for low levels of ozone
