Half-mask respirators are essential equipment in automotive, construction and industrial settings.
They can protect the wearer from lead poisoning, dust and fumes, but they must be properly fitted and maintained.
First, before you begin, wash your hands thoroughly before touching the respirator mask. If you have used a respirator before that fit you, choose the same make, model and size.
Experts at cdph.ca.gov say you should inspect the respirator for damage if you've used it before. If it's damaged, DO NOT USE IT. Replace it with a new one.
* Do not allow hair, jewelry, glasses, clothing, or anything else to prevent proper placement of your face and the respirator.
Putting on the respirator
* Position the respirator in your hand with the nose piece at your fingertips. Cup it in your hand allowing the headbands to hang down below. Hold the respirator under your chin with the nosepiece up then pull the strap up and over your head.
* Place your fingertips from both hands at the top of the metal nose clip (if present). Slide fingertips down both sides of the metal strip to mold the nose area to the shape of your nose.
Checking your seal
* Place both hands over the respirator, take a quick breath in to check whether the respirator seals tightly to the face. Place both hands completely over the respirator and exhale. If you feel leakage, there is not a proper seal.
* If air leaks around the nose, readjust the nosepiece as described. If air leaks at the mask edges, re-adjust the straps along the sides of your head until a proper seal is achieved.
If you cannot achieve a proper seal due to air leakage, ask for help or try a different size or model.
Always wash your hands thoroughly after removing the respirator mask.
