Request a QuoteWhat is Chemical Exposure Monitoring? It is the measurement of worker exposure to hazardous chemicals in the workplace to ensure exposure does not exceed the Permissible Exposure Limits (PEL) set by MOM.
Is it required? Yes. Under the Workplace Safety and Health (General Provisions) Regulations, employers must conduct regular monitoring if workers are exposed to toxic chemicals.
Who can help? Qsafe Pte Ltd is a MOM-approved industrial hygiene monitoring company that measures chemical exposure, prepares reports, and submits them to MOM on your behalf.
What Is Chemical Exposure Monitoring?
Chemical exposure monitoring is the process of measuring and assessing worker exposure to hazardous chemicals in the workplace. It helps employers understand how organic solvents, acids, bases, and other toxic substances contribute to occupational health risks.
In Singapore, the Ministry of Manpower (MOM) outlines requirements for monitoring chemical exposure and reporting results under the Workplace Safety and Health (General Provisions) Regulations.
Qsafe supports businesses by conducting chemical exposure assessments, identifying exposure risks, documenting measurement results, and preparing reports for MOM submission.
Common Chemicals We Monitor
Qsafe provides monitoring for a wide range of hazardous chemicals, including:
Exposure in painting, printing, cleaning, and chemical manufacturing.
Exposure to sulfuric acid, hydrochloric acid, ammonia, and sodium hydroxide.
Exposure to lead, cadmium, chromium, and nickel in industrial processes.
Exposure to formaldehyde, benzene, toluene, and xylene.
Exposure to respirable dust, welding fumes, and other airborne particulates.
Exposure to ammonia, chlorine, carbon monoxide, and other toxic gases.
Why Is Chemical Exposure Monitoring Important?
Regular monitoring of chemical exposure helps businesses:
- Identify workers exposed to hazardous chemicals
- Ensure exposure levels do not exceed MOM’s Permissible Exposure Limits (PEL)
- Support compliance with Workplace Safety and Health regulations
- Determine whether existing control measures are effective
- Plan suitable respiratory protection and engineering controls
- Maintain documented exposure records for workplace safety management
Early identification of exposure hazards allows employers to take corrective action before prolonged exposure causes occupational diseases.
Monitoring Frequency Requirements
Under MOM requirements, monitoring frequency depends on the Permissible Exposure Limit (PEL) ratio:
| Ratio (%) of concentration of contaminants compared to PEL | Frequency of monitoring |
|---|---|
| Less than 10% PEL | No monitoring is required. A re-assessment should be carried out if there is any change in the process. |
| 10% to 50% PEL | At least once a year. |
| More than 50% to 100% PEL | At least once every 6 months. |
| More than 100% PEL | At least once every 3 months, until the exposure is reduced to below the PEL by appropriate control measures. |
