A respirator fit test together with lung function testing are an important part of ensuring the health and safety of workers who may be exposed to hazardous materials. A respirator fit test determines whether a worker can wear a respirator safely and effectively. It is important for workers to receive a fit test before they begin using a respirator, and it is also important for employers to ensure that their workers are tested regularly.
According to experts who provide WHS consultations, there are a number of reasons why respirator fit testing is important.
There are generally two ways of carrying out a respirator fit test; qualitative and quantitative. Qualitative fit testing relies on the worker's sense of taste, smell or irritation in order to determine whether or not the respirator is a good fit. This method is generally less reliable than quantitative fit testing, which uses a machine to measure the amount of leakage around the seal of the mask. Quantitative fit testing is more expensive and requires special training, but it is generally considered to be more accurate.
Respirator fit testing is an important part of ensuring that workers are able to safely and effectively do their jobs. By understanding what respirator fit testing is and how it works, employers can make sure that their employees are protected from harmful substances in the workplace. In most countries it is required by law that employers carry out regular fit testing on their employees who use respirators.
