To reduce formaldehyde exposure, use formaldehyde-free products, ensure proper ventilation at home and work, and maintain indoor humidity levels below 50%. Additionally, wash new clothing and home textiles before use and choose solid wood furniture over pressed wood products.
How is formaldehyde exposure monitored in occupational settings?
Formaldehyde exposure in occupational settings is monitored using air sampling methods such as passive badges or active sampling pumps with tubes containing absorbent materials. Additionally, biological monitoring through urine or blood tests may be used to assess exposure levels. Regular workplace assessments and adherence to safety guidelines help minimize risks.
What are the symptoms of formaldehyde exposure?
Symptoms of formaldehyde exposure include irritation of the eyes, nose, and throat, coughing, wheezing, and skin irritation. In higher concentrations, it can cause chest tightness, difficulty breathing, and in extreme cases, can lead to serious respiratory complications.
