Testers, Protective Mask/Respirator Leakage

Definition : Testers designed to check the leakage of protective masks and/or respirators that are used against contaminating (e.g., chemical, biological, toxic industrial) agents. These testers are either stand-alone units or portable particle counters that compare the numerical value of particles in the environment with the particles in the air inside the wearer's mask, giving as a result a ratio (i.e., a protection factor) which value should be greater than a pre-established value (e.g., 1,667). Other testers employ aerosol generators as an integral part to perform the leakage test. The leakage test ensures that the mask is the proper size for the individual wearer and that there are no critical leaks in the mask or respirator. Some testers can also check the functioning of the outlet valve and the drink tube system.
