Formaldehyde Monitoring
Formaldehyde vapour exposure assessment in laboratories and manufacturing
What Is Formaldehyde Monitoring?
Formaldehyde monitoring measures worker exposure to this colourless, pungent gas classified as carcinogenic to humans (IARC Group 1), causing nasopharyngeal cancer and leukaemia. Formaldehyde is widely used in laboratories, mortuaries, resin manufacturing, and composite wood product processing.
The WES of 1 ppm TWA-8h and 2 ppm STEL will be reduced to 0.3 ppm TWA and 0.6 ppm STEL under the new WEL — a 70% reduction. Many current workplaces will exceed the new limits, requiring ventilation upgrades and process controls.
How Is It Done?
Personal sampling using DNPH-coated silica gel cartridges. Analysis by HPLC-UV (NIOSH 2016). Real-time direct-reading instruments for peak/STEL assessment.
When You Need This
- +Histology and anatomy laboratories using formalin
- +Mortuary and embalming operations
- +Resin manufacturing and composite board production
- +WEL transition — current controls may be insufficient
- +Indoor air quality assessment in new buildings (off-gassing)
