Chemical Health Risk Assessment (CHRA) in Malaysia
Professional Chemical Health Risk Assessment (CHRA) Services

FESLAB SDN BHD provides professional Chemical Health Risk Assessment (CHRA) services throughout Malaysia, conducted by a CHRA Assessor registered with the Department of Occupational Safety and Health (JKKP/DOSH) Malaysia.
CHRA is an assessment of health risks arising from the use, handling, storage or exposure to chemicals hazardous to health at the workplace.
The assessment helps employers identify chemical health hazards, evaluate potential employee exposure, review existing control measures and determine appropriate recommendations to protect workers' health.

What Is CHRA?
Chemical Health Risk Assessment (CHRA) is a systematic assessment of health risks associated with chemicals hazardous to health used or generated during workplace activities.
The assessment considers factors such as:
Chemical Hazard → Work Activity → Route of Exposure → Exposure Potential → Existing Control Measures → Risk Evaluation → Recommendations
The objective is to determine whether existing control measures adequately protect employees and whether further action is required.
What Is Assessed During CHRA?
Depending on the workplace and chemical processes involved, the CHRA may include:
Chemical Register & Safety Data Sheets
The assessor reviews relevant chemical information, including the workplace chemical register and available Safety Data Sheets (SDS).
Workplace Processes
Work activities involving chemicals are reviewed to understand how employees may potentially be exposed.
Examples include:
Mixing • Spraying • Painting • Cleaning • Degreasing • Welding • Grinding • Laboratory Work • Chemical Transfer • Maintenance • Production Processes • Material Handling
Routes of Exposure
Potential routes of occupational exposure may include:
- Inhalation
- Skin contact
- Eye contact
- Accidental ingestion where relevant
Existing Control Measures
Existing workplace controls are evaluated, including:
Local Exhaust Ventilation (LEV) • General Ventilation • Process Enclosure • Isolation • Work Procedures • Chemical Storage • Personal Protective Equipment (PPE) • Hygiene Practices
Employee Exposure
The assessment considers the nature of the work, frequency and duration of potential exposure, chemical properties and existing controls.
CHRA Recommendations
Depending on the assessment findings, recommendations may include:
- Chemical Exposure Monitoring
- Local Exhaust Ventilation (LEV) Testing
- Improvement of Engineering Controls
- Process Enclosure or Isolation
- Workplace Ventilation Improvements
- Review of Work Procedures
- Chemical Substitution
- Personal Protective Equipment
- Employee Training
- Medical Surveillance where applicable
- Chemical Management Improvements
- Further Occupational Hygiene Assessment
Recommendations are determined according to the hazards, exposure circumstances and assessment findings at the workplace.
Chemical Exposure Monitoring Following CHRA
Where chemical exposure monitoring is recommended, FESLAB can assist with appropriate occupational hygiene services according to the required scope.
Chemical exposure monitoring can help determine workers' exposure to specific airborne contaminants and support evaluation of the effectiveness of workplace control measures.
LEV Testing Following CHRA
Where a Local Exhaust Ventilation (LEV) system is used as an engineering control, examination and testing may be recommended to evaluate its performance.
FESLAB also provides LEV Testing by registered Hygiene Technician 2 (HT2) / Juruteknik Higien 2 with JKKP/DOSH Malaysia, subject to the applicable scope and requirements.
Why Is CHRA Important?
A properly conducted CHRA helps employers to:
✓ Identify chemical health hazards
✓ Understand potential worker exposure
✓ Evaluate existing control measures
✓ Identify areas requiring improvement
✓ Determine the need for exposure monitoring
✓ Determine appropriate engineering controls
✓ Support occupational health management
✓ Improve chemical safety at the workplace
✓ Support compliance with applicable JKKP/DOSH requirements
CHRA Technical Report
Following the assessment, a professional CHRA report is prepared based on the assessment findings.
The report may include relevant information concerning:
- Chemicals hazardous to health
- Work units and processes
- Potential exposure
- Existing control measures
- Risk assessment findings
- Recommended control measures
- Chemical exposure monitoring requirements
- LEV-related recommendations
- PPE recommendations
- Medical surveillance recommendations where applicable
- Other occupational hygiene recommendations
The CHRA report provides the employer with a structured basis for managing chemical health risks at the workplace.
