INTRODUCTION TO CHEMICAL HEALTH RISK ASSESSMENT (CHRA)

In Malaysia, a Chemical Health Risk Assessment (CHRA) is required under the Occupational Safety and Health (Use and Standard of Exposure of Chemicals Hazardous to Health) Regulations 2000 (USECHH Regulations). 

This assessment evaluates the potential health risks associated with workplace chemicals. By identifying hazards, assessing exposure levels, and recommending control measures, CHRA helps organizations prevent chemical-related illnesses and maintain a safer work environment.

OBJECTIVES OF CHEMICAL HEALTH RISK ASSESSMENT (CHRA)

The primary goal of CHRA is to safeguard employees while supporting operational safety. Key objectives include:

• Identify and catalogue all chemicals used in the workplace to ensure proper management of potential hazards and inform training programs for staff.
• Evaluate the routes and levels of employee exposure to determine how chemicals may affect their health.
• Assess potential short-term and long-term health risks to protect employees from immediate and chronic effects.
• Recommend effective control measures to minimize exposure and maintain a safer work environment.
• Ensure compliance with local and international safety regulations to meet legal and industry requirements.

INDUSTRIES BENEFITING MOST FROM CHRA

• Manufacturing: Chemical processing, electronics assembly, and metalworks
• Pharmaceuticals and Laboratories: Research labs and production facilities
• Construction and Cleaning Services: Work involving solvents, paints, and cleaning agents
• Agriculture and Pesticide Handling: Farms, nurseries, and the use of agrochemicals
• Food and Beverage Production: Handling preservatives, sanitizers, and additives
