The use of respirators and gas detectors in accordance with OSHA 29 CFR standards
Respirators are used to prevent workers from inhaling small particles, including airborne or aerosolized infectious agents. They must be provided and used in accordance with OSHA’s Respiratory Protection standard at 29 CFR 1910.134, and must be certified by the National Institute for Occupational Safety and Health (NIOSH).
Gas monitors are small and light enough to be worn continuously while working, and should be worn by workers at all times. Test for oxygen content, flammable gases and vapors, and toxic air contaminants with a properly calibrated monitor before an employee enters or reenters the workspace after 20 minutes as well as the entire time they’re working, to stay ahead of potential changes. If a workspace has the potential to contain gases that could stratify, test at the top, middle and bottom of the confined space at 4-foot intervals. Test in 4-foot areas around the worker as well, and move sample probes slowly enough to complete testing properly before moving on. Add extra time for gas monitors to respond if you have attached hosing or other extensions to the monitors.
