• Description:
  Tests were conducted to determine the breakthrough times for methylene-chloride (75092) using commercially available negative pressure organic vapor cartridge and canister respirators. Challenge concentrations ranging from 50 to 1000 parts per million (ppm) were used in the study. Using a flow rate of 64 liters/minute, the cartridges and canisters were tested as they were received from their manufacturers. Relative humidities of 50% and 80% were used. Cartridge breakthrough times were extremely short when tested at 80% relative humidity for all of the concentrations studied. Chin style canisters contained 2.5 to 3.0 times more sorbent (194.3 grams charcoal) than the cartridge types and still gave a breakthrough time of only 100 minutes when tested at 125ppm and 80% relative humidity. Front mounted/back mounted canisters contained 10.5 to 11 times more sorbent than cartridges and had a breakthrough time of more than 10 hours at a concentration of 125ppm and relative humidity of 80%. However, when the challenge concentration was increased to 1000ppm, the breakthrough time was reduced to 5 hours. [Description provided by NIOSH]
