This document particularly highlights fit testing practises in the USA and UK – check your local requirements for respirator fit testing.  \nIntroduction  \nDo you know if your workers are wearing tight-fitting respirators that actually fit them?  \nTight-fitting respirators must seal to the wearer’s face in order to provide expected protection. If there is a leak, they may be exposed to harmful airborne contaminants. Fit testing is required by law in many different countries around the world and is being increasingly adopted by companies as best practice even where there is not a mandatory requirement to fit test.  \nWhat is fit testing?  \nA respirator fit test can be defined (1) as:  \n“…a method for checking that a tight-fitting facepiece matches the person's facial features and seals adequately to the wearer’s face. It will also help to identify unsuitable facepieces which should not be used.”  \nWhy fit testing?  \nA good fit means the respiratory protective device (RPD) will seal to your skin. A respirator can only provide respiratory protection to the wearer when air passes through the filter. Air will take the path of least resistance, so if there isn't a good seal, some of the contaminated the air will go around rather than through the respirator – and therefore lessen the protection.  \nEvery wearer's face is different in shape, size and features. Tight-fitting respirators are also available in a wide range of shapes, styles, materials and sizes. Unfortunately, there is no single tight-fitting respirator that can be expected to fit every possible wearer. Therefore, the fit of a respirator is personal, individual and unique to each wearer. The only way to know if a respirator can provide an adequate seal to a worker is to fit test each respirator-wearer combination.  \nFit testing as part of your respiratory protection program  \nImplementing an effective respiratory protection program should be a methodical and documented process. All programs should start with an exposure and risk assessment to determine the level of adequate respiratory protection required. After this, the focus is the selection and fit testing of a respiratory protective device that is suitable for both the workplace and the worker. A suitable tight-fitting RPD needs to be compatible with others items of PPE, be comfortable to wear and importantly fit the worker. In some countries, a mandatory medical evaluation may be required prior to fit testing. Finally, the entire program should be documented, particularly worker training in the use, limitations, maintenance and fitting of the respirator completes the process.  \nFit testing is a key part of a workplace respiratory protection program. Obviously, a fit test gives an assessment of how well the respirator fits the worker. But a fit test also helps with the assessment of the respirator’s comfort, compatibility with other PPE and overall suitability for the wearer, along with being an ideal training opportunity for the worker on the use and correct fitting of the product.  \nWhat type of RPE should be fit tested?  \nAny tight-fitting facepiece should be fit tested. These include filtering facepiece respirators (disposable respirators, commonly referred to as ‘dust masks’), half-masks with filters and full-face masks with filters. Any tight-fitting facepiece or mask that is connected to powered or supplied air system should also be fit tested; this includes tight-fitting face masks used with turbos, breathable compressed air or self-contained breathing apparatus.  \nOnly respirators that rely upon positive air flow through a loose-fitting headtop do not require face fit testing. Such products may be selected for a variety of reasons, which may include the need for higher protection levels, worker facial hair","cbCailtRDlzTz4hG","https://ap.wps.com/l/cbCailtRDlzTz4hG","pdf",192389,"English","# Introduction\n## What is fit testing?\n## Why fit testing?\n## Fit testing as part of your respiratory protection program\n## What type of RPE should be fit tested?\n## Fit test methods and regulations\n## Fit test methods\n### Qualitative (QLFT)\n### Quantitative (QNFT)","[{\"question\":\"What is the purpose of tight-fitting respirator fit testing?\",\"answer\":\"Fit testing checks that a tight-fitting facepiece matches a wearer’s facial features and seals adequately.
