What is the permissible long-term exposure limit for formaldehyde?

Formalized standards regarding exposure limits for formaldehyde are established to ensure health and safety in various environments, including funeral homes where formaldehyde is often used in embalming processes. The permissible long-term exposure limit for formaldehyde is set at 0.75 parts per million (ppm) averaged over an eight-hour workday. This regulation is based on research that indicates higher concentrations can pose serious health risks, including respiratory issues and cancer.

The choice of 0.75 ppm aligns with Occupational Safety and Health Administration (OSHA) standards and other health guidelines, which aim to protect workers from the potential adverse effects of prolonged exposure to this chemical. Understanding the correct exposure limit is crucial for ensuring both compliance with regulations and the safety of personnel working in settings that utilize formaldehyde regularly.
