Chemical Exposure Monitoring (CEM) in Malaysia
Professional Chemical Exposure Monitoring Services

FESLAB SDN BHD provides Chemical Exposure Monitoring (CEM) services throughout Malaysia to assess workers' exposure to hazardous chemicals in the workplace.
Chemical Exposure Monitoring is an important component of occupational hygiene and workplace chemical risk management. Monitoring helps employers determine the actual level of employee exposure to hazardous chemicals generated, handled or released during work activities.
Chemical Exposure Monitoring may be recommended following a Chemical Health Risk Assessment (CHRA) when quantitative exposure monitoring is required to evaluate workers' exposure.
What is Chemical Exposure Monitoring?
Chemical Exposure Monitoring involves measuring the concentration of hazardous chemicals to which employees may be exposed during their normal work activities.
Depending on the chemical and exposure route, monitoring may involve personal air sampling, area sampling or other appropriate occupational hygiene sampling methods.
Samples collected during monitoring are analysed using suitable analytical methods to determine the concentration of the chemical contaminants.
The results can then be evaluated against applicable occupational exposure limits and used to determine whether additional exposure controls are required.
Chemical Exposure Monitoring by Hygiene Technician 1
FESLAB provides Chemical Exposure Monitoring conducted by a Hygiene Technician 1 (HT1) registered with the Department of Occupational Safety and Health (DOSH/JKKP) Malaysia, where applicable.
Monitoring can be planned according to workplace activities, chemicals used, employee exposure groups and recommendations stated in the CHRA report.
Chemicals That May Require Exposure Monitoring
Depending on the workplace process and CHRA recommendations, monitoring may include substances such as:
- Organic solvents and solvent vapours
- Toluene
- Xylene
- Benzene
- Acetone
- Methanol
- Isopropyl alcohol
- Acids and alkalis
- Welding fumes
- Metal fumes
- Lead and other heavy metals
- Dust and particulates
- Silica-containing dust
- Oil mist
- Chemical vapours
- Gases
- Other hazardous chemicals used or generated in industrial processes
The actual contaminants selected for monitoring should be based on the chemicals, processes, exposure pathways and findings applicable to the specific workplace.
Our Chemical Exposure Monitoring Process
Our service may include:
- Review of the CHRA recommendations and workplace processes.
- Identification of chemicals or contaminants requiring monitoring.
- Identification of relevant employees or Similar Exposure Groups (SEG).
- Selection of appropriate sampling methods and equipment.
- Personal or workplace air sampling.
- Laboratory analysis using appropriate analytical methods.
- Evaluation of monitoring results.
- Preparation of a Chemical Exposure Monitoring report.
- Recommendations for exposure control where necessary.
Why Chemical Exposure Monitoring Is Important
Workers in manufacturing and industrial environments may inhale hazardous dust, fumes, mist, gases or vapours without immediately experiencing obvious symptoms.
Chemical Exposure Monitoring provides quantitative information that helps employers understand the actual exposure level and evaluate the effectiveness of existing control measures.
The results may also assist in determining whether improvements are required for:
- Local Exhaust Ventilation (LEV)
- Process enclosure
- General ventilation
- Work procedures
- Chemical handling practices
- Personal Protective Equipment (PPE)
- Respiratory protection
- Employee exposure management
