What is the permissible exposure limit for formaldehyde?

The permissible exposure limit (PEL) for formaldehyde is significant in understanding workplace safety, particularly for industries where formaldehyde is used or produced. The correct answer indicates that the PEL is set at 0.75 parts per million (ppm). This standard helps to protect workers from potential health risks associated with exposure to formaldehyde, which is a known irritant and a potential carcinogen.

The level of 0.75 ppm is established based on research indicating where adverse health effects may start to occur, thus ensuring that exposure is kept to a minimum to promote occupational health. Regulations set by agencies such as OSHA (Occupational Safety and Health Administration) are designed to safeguard against both short-term and long-term effects of harmful substances in the workplace.

This knowledge is critical for those in safety, health, construction, or any fields that may involve exposure to formaldehyde, highlighting the importance of compliance with these limits in workplace environments.
