Question

honeywell pa700 series paprs can be used for protection from (check all that apply):
airborne particulate contaminants (biological or chemical) when used with high-efficiency particulate filters
bad odors
chemical gases and vapors when used with the appropriate chemical cartridges
oxygen deficient atmospheres

Explanation:

• Airborne particulate contaminants (biological or chemical) when used with high - efficiency particulate filters: PAPRs (Powered Air - Purifying Respirators) with high - efficiency particulate filters are designed to filter out airborne particulates, including biological (like bacteria, viruses) and chemical particulates. So this option applies.
• Bad odors: PAPRs are not primarily designed for odor control. Odor - control usually requires specialized odor - absorbing media, and PAPRs focus on particulate and some chemical vapor/gas filtration. So this option does not apply.
• Chemical gases and vapors when used with the appropriate chemical cartridges: When used with chemical cartridges, PAPRs can filter chemical gases and vapors as the cartridges are designed to adsorb or react with specific chemicals. So this option applies.
• Oxygen deficient atmospheres: PAPRs do not provide oxygen. They only purify the air that is available. For oxygen - deficient atmospheres, self - contained breathing apparatus (SCBA) or supplied - air respirators with oxygen sources are needed. So this option does not apply.

Answer:

• Airborne particulate contaminants (biological or chemical) when used with high - efficiency particulate filters
• Chemical gases and vapors when used with the appropriate chemical cartridges
