What health hazards are associated with exposure to formaldehyde?
Formaldehyde is a colorless, flammable gas that poses significant health risks to humans and other animals. Exposure to this aldehyde is primarily hazardous due to its extreme irritation of the mucous membranes.1
Beyond its immediate irritant properties, formaldehyde is classified as a human carcinogen, meaning it is a substance known to cause cancer.1
In indoor environments, formaldehyde can accumulate through off-gassing from various building materials, such as particleboard and plywood, as well as from dry-cleaned textiles. Because prolonged exposure to such contaminants can lead to serious health issues, it is essential to prioritize safety by ensuring adequate ventilation and limiting exposure to these sources in living and working spaces.2
