Einstein

This page provides an expert technical advisor which will assist you in choosing the proper respirator for your workplace. You will be given a series of choices, select the choices which best describe your workplace and working conditions. The advisor will then use your selections to recommend a respirator.

This advisor is based on the NIOSH Respirator Decision Logic and the OSHA Respirator Standard. [29 CFR 1910.134]

There are OSHA standards which have specific respirator requirements when certain contaminants are present in the workplace. Please review this list before proceeding with this advisor. When these contaminants are present in the workplace, the substance specific standard takes precedence over any recommendations provided by this selection decision logic.

Remember, that there are many variables which can influence respirator selection. Therefore, the result from this advisor does not guarantee compliance with OSHA regulations and should only be used as initial guidance.

  • Percent of oxygen in the air. If you are working at normal atmospheric conditions, use a value of 21%.

  • For gaseous contaminants, the maximum concentration of contaminants in the workplace in units of parts per million or milligrams per cubic meter.
