What are the Regulatory Standards for Formaldehyde?
Various regulatory agencies have established exposure limits for formaldehyde to protect public health. The Occupational Safety and Health Administration (OSHA) has set a permissible exposure limit (PEL) of 0.75 parts per million (ppm) as an 8-hour time-weighted average (TWA) and a short-term exposure limit (STEL) of 2 ppm. The Environmental Protection Agency (EPA) regulates formaldehyde emissions from certain wood products, while the World Health Organization (WHO) recommends a limit of 0.1 mg/m³ (0.08 ppm) for indoor air quality.
