What is the NIOSH short-term (15-minute) REL for formaldehyde?

Explanation:
NIOSH uses a short-term exposure limit to protect people from acute effects that can occur during brief spikes in a contaminant’s concentration. For formaldehyde, the 15-minute short-term REL (STEL) is 0.1 ppm. This level is set to prevent immediate irritation of the eyes, nose, and throat that can happen with a short exposure, while also considering formaldehyde’s irritant and carcinogenic properties. There is also an 8-hour time-weighted average REL for formaldehyde (much lower, around 0.016 ppm) to address cancer risk from long-term exposure, but the 0.1 ppm value specifically targets short-term pulse exposures. The other numbers do not reflect the official short-term limit.
