What is the first basic step in choosing proper respiratory equipment?

• A. Determine Hazard
• B. Select equipment approved for function
• C. Assure device performs intended function
• D. Check fit testing requirements

Answer: (A)

Determining the hazard is the first step because you must know exactly what you’re protecting against before selecting equipment. Identifying the contaminant type (dust, vapor, gas, mist), its concentration or exposure level, duration, and the work environment tells you what kind of respirator is needed and what features or cartridges are required. If you don’t know the hazard, you might choose a respirator that won’t protect against the actual contaminant or won’t provide enough protection, or you might decide protection isn’t needed when it is. Once the hazard is clear, you can pick equipment that is approved for that function and capable of handling the specific contaminant, then verify it can deliver the necessary protection and proceed to fit testing and seal checks to ensure the wearer is properly protected.
