Each person who uses formaldehyde as a regular part of their job must have their exposure monitored periodically, according to OSHA regulations.
There are two conditions that must be met to comply with the OSHA Standards for personal exposure in the workplace. First, the concentration for an 8 hour period must be less than 0.75 ppm. Second, the maximum exposure during any 15 minute interval must be less than 2.0 ppm. There is also an “action level” at 0.5 ppm for an 8 hour period. Above the action level more frequent monitoring is needed to avoid the need for protective equipment and for medical testing.
