FFP2 and P2 respirators are not NIOSH-approved, so they cannot satisfy OSHA-required workplace use in the US. This guide covers the legal rule, the ended COVID exception, the FFP2-to-N95 and FFP3-to-P100 translation table, voluntary-use cases, the reverse question abroad, and a spec-conversion worked example.

AS/NZS 1716 is the Australian and New Zealand respirator standard: P1, P2, and P3 filter classes, certification marks, and the rule that P3 protection requires a full facepiece. This guide covers silica and bushfire selection, the engineered-stone ban, AS/NZS 1715 protection factors, and the N95-to-P2 translation both ways.
