In cleaning, maintenance, and facility operations, the use of chemicals is unavoidable. From disinfectants and degreasers to solvents and detergents, each product can pose potential risks if not handled correctly. Without proper controls, these chemicals can cause harm to workers, damage property, and even impact the environment.
That’s where a Chemical Health Risk Assessment (CHRA) comes in. More than just a compliance checklist, CHRA is a vital part of ensuring workplace safety and long-term operational sustainability.
At MGC Maintenance, every project we undertake is guided by CHRA principles, ensuring safe, efficient, and compliant cleaning practices for our clients.
What Is Chemical Health Risk Assessment (CHRA)?
A Chemical Health Risk Assessment (CHRA) is a formal evaluation of how hazardous chemicals are used, stored, or handled at a workplace. Its purpose is to identify potential health risks to employees, evaluate exposure levels, and implement the right control measures to prevent accidents and long-term illnesses.
The CHRA process generally involves:
- Identifying hazardous substances used or produced during work.
- Evaluating exposure risks, including inhalation, ingestion, or skin absorption.
- Assessing control measures currently in place and identifying areas for improvement.
- Recommending preventive actions such as engineering controls, substitution with safer products, or proper PPE (Personal Protective Equipment).
In short, CHRA ensures every cleaning or maintenance task involving chemicals is performed safely and responsibly, protecting both workers and clients.
Who Needs CHRA?
CHRA applies to any workplace where employees are exposed to hazardous chemicals, whether directly or indirectly. This includes:
- Construction and post-renovation cleaning projects
- Industrial maintenance and factory cleaning
- Hospitals, laboratories, and schools
- Offices and commercial facilities using industrial-grade cleaning agents
Even smaller operations benefit from CHRA, as it helps reduce liability, ensure compliance, and maintain a healthier working environment.
Risks That CHRA Helps Prevent
Conducting a proper CHRA mitigates multiple types of risks, including:
1. Health Risks
Workers may suffer from skin irritation, respiratory problems, eye injuries, or even long-term effects such as chemical sensitisation and organ damage. CHRA helps ensure chemicals are properly labelled, stored, and used with adequate ventilation and protective gear.
2. Environmental Risks
Improper handling or disposal of cleaning agents can cause soil or water contamination. CHRA helps companies implement eco-friendly disposal practices and adopt safer chemical alternatives.
3. Legal and Financial Risks
Neglecting CHRA can lead to regulatory fines, reputational damage, and compensation claims. Proactively conducting assessments demonstrates compliance and helps avoid costly penalties.
Legal and Regulatory Context in Malaysia
In Malaysia, CHRA is a mandatory requirement under the Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000.
This regulation requires employers to:
- Conduct a CHRA for any work involving hazardous chemicals.
- Engage a registered assessor recognised by the Department of Occupational Safety and Health (DOSH).
- Review and update the assessment at least once every five years or whenever changes occur in chemical use or work processes.
- Provide workers with training, PPE, and access to Safety Data Sheets (SDS).
By following these legal standards, companies protect their workers while avoiding compliance violations that could impact business operations.
Why Choose a Cleaning Contractor Who Adheres to CHRA Standards
Partnering with a cleaning or maintenance contractor who observes CHRA best practices offers significant advantages:
1. Ensured Compliance
Contractors familiar with CHRA automatically integrate safety into their workflow. This means all cleaning agents, disinfectants, and solvents are handled, stored, and disposed of in accordance with legal requirements.
2. Reduced Health and Safety Incidents
Proper risk assessment prevents accidents such as chemical burns, allergic reactions, or inhalation hazards. It ensures workers are properly trained and equipped before handling any hazardous material.
3. Protection of Your Company’s Reputation
Clients increasingly value responsible, compliant contractors. Demonstrating that your site follows CHRA principles enhances your image as a professional and safety-conscious business.
4. Long-Term Sustainability
By prioritising CHRA, contractors can transition to greener cleaning solutions that are both safe and environmentally sustainable, supporting corporate ESG (Environmental, Social, and Governance) goals.
For businesses that want peace of mind and full compliance, partnering with MGC Maintenance ensures your cleaning services meet regulatory and ethical standards from start to finish. You can check out our commercial maintenance services for your cleaning needs.
How CHRA Is Implemented in Cleaning Projects
Implementing CHRA involves several key steps:
- Chemical Inventory
List all chemicals used on-site, including cleaning agents, disinfectants, and solvents. - Hazard Identification
Evaluate each chemical’s potential to cause harm through inhalation, skin contact, or accidental ingestion. - Exposure Assessment
Measure how often and how long workers are exposed to each substance, and assess ventilation and control measures. - Risk Evaluation
Compare exposure levels to permissible limits set by DOSH or international guidelines. - Control Measures
- Substitute hazardous chemicals with safer alternatives.
- Implement engineering controls such as fume hoods or proper ventilation.
- Provide PPE, safety training, and emergency response plans.
- Substitute hazardous chemicals with safer alternatives.
- Monitoring and Review
Regularly monitor exposure levels and update the CHRA whenever new chemicals or processes are introduced.
A Practical Example: CHRA in Action
Imagine a construction cleanup site using acid-based tile cleaners and degreasers. Without CHRA, workers may unknowingly be exposed to corrosive vapours, leading to skin burns or respiratory irritation.
With CHRA in place:
- The contractor substitutes strong acids with neutral pH alternatives.
- Workers receive training on safe dilution and application.
- Adequate ventilation and PPE are enforced.
- Chemical waste is properly contained and disposed of.
The result? A cleaner site, zero incidents, and complete compliance with safety regulations.
Conclusion
CHRA is not just a legal requirement; it’s a commitment to workplace safety, health, and professionalism. Whether you manage a construction site, industrial plant, or commercial facility, ensuring your cleaning contractor adheres to CHRA standards protects your workers, your reputation, and your bottom line.
