Laboratory Safety/Respiratory Protection

Lab workers may be required to wear specific respiratory protection to safely work with hazardous materials. In this image, researchers are shown working with uranium. Avoiding inhalation of radioactive particles is an important consideration here.

Respiratory protection (personal protective equipment that shields the lungs, mouth, and other parts of the respiratory system) may be a requirement or simply a preference depending on the work being done. While a simple face mask, such as an N95 mask, may be worn by anyone in any situation if they feel it makes them comfortable (barring local laws and dress requirements), more advanced technology such as cartridge-fitted respirators and powered breating apparatuses requires preparation and notification to groups that have control over a laboratory.

An important factor in using respiratory protection is the fit of the mask. A laboratory will often have a respiratory protection plan when it is applicable, which can require individuals to undergo a fit test before using a mask or breathing apparatus. The fit test ensures that the mask is actually working, and this often requires a person to have a clean-shaven face. Changes in facial structure, such as surgery, weight gain, or weight loss can necessitate re-taking a fit test.
