Indoor air quality (IAQ) directly affects the health, comfort, and productivity of building occupants — whether in homes, offices, or industrial spaces. Poor IAQ can cause symptoms like eye and throat irritation, headaches, and fatigue, and contribute to long-term respiratory issues, absenteeism, and reduced productivity.

Eurofins Environment Testing Malaysia provides comprehensive IAQ testing and monitoring to help businesses maintain a healthy environment, stay compliant with regulatory standards, and protect their people.

Our key IAQ services

• Chemical contaminant testing – Carbon monoxide (CO), carbon dioxide (CO2), volatile organic compounds (VOCs), formaldehyde
• Biological contaminant testing – Airborne mould, bacteria, and fungal spore counts
• Physical parameter monitoring – Temperature, relative humidity, air movement, and illumination levels
• Particulate matter testing – Dust and respirable particulate concentration
• Ventilation assessment – Evaluation of MVAC (Mechanical Ventilating and Air Conditioning) system performance and air exchange rate

Under the Occupational Safety and Health Act 1994 (Act 514), employers and building occupiers have a duty to provide a safe environment for employees and occupants. Our testing follows the Industry Code of Practice on Indoor Air Quality, which sets standards for:

• Acceptable exposure limits for chemical and biological contaminants
• Acceptable values for specific physical parameters
• Identifying, evaluating, and controlling indoor air contaminants
• Other relevant occupational safety and health measures

Chemical Health Risk Assessment (CHRA)

The Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000 (USECHH Regulations) require employers at workplaces where hazardous chemicals are used to conduct a Chemical Health Risk Assessment (CHRA). This assessment supports employers in deciding on appropriate control measures, employee induction and training, as well as monitoring and health surveillance activities needed to protect employees exposed to hazardous chemicals.

A CHRA aims to:

• Identify hazards posed by each chemical substance used, stored, handled, or transported at the workplace
• Evaluate employees' degree of exposure to hazardous chemicals through inhalation, skin contact, and/or ingestion
• Assess the adequacy of existing control measures
• Determine the significance of health risks posed by the hazardous chemicals
• Recommend appropriate control measures to reduce risks to as low as reasonably practicable (ALARP)

Workplace air can carry more than what the eye sees — vapours, fumes, dust, and mists from everyday industrial processes can silently affect employee health over time. Chemical exposure monitoring (CEM) measures exactly how much of these hazardous substances employees are exposed to, so employers can act before it becomes a health risk.

Under the Occupational Safety and Health (Use and Standards of Exposure of Chemicals Hazardous to Health) Regulations 2000 (USECHH Regulations), employers must monitor employee exposure to hazardous chemicals using an approved method of monitoring and analysis. Exposure levels are assessed against the Permissible Exposure Limits set out in Schedule I and Schedule II of the USECHH Regulations. Monitoring must be carried out by a hygiene technician registered with DOSH Malaysia, and where employees are exposed to chemicals listed under Schedule II, monitoring must be repeated at intervals of not more than six months. 

Why chemical exposure monitoring matters:

• Detects pollutant concentrations in the workplace before they exceed safe limits
• Flags exposure levels that go beyond the permitted threshold
• Confirms employee exposure stays within OSH standards as stated in the chemical's Safety Data Sheet (SDS)
• Gives employers the data needed to strengthen control measures and protect long-term employee health

Not all workplace hazards are visible — dust, fume, vapour, and gas released during industrial processes can linger in the air long after the work is done. A Local Exhaust Ventilation (LEV) system is the engineering control designed to capture these contaminants right at the source, before workers ever breathe them in.

Installing an LEV system isn't enough on its own — it needs to keep performing as designed. LEV systems must be tested and examined at least once every 12 months, or more frequently if specified by the design engineer, to confirm the system is still capturing and removing contaminants effectively. Inspection is also required when a new system is first commissioned, to establish baseline performance data that future testing will be compared against — as outlined in DOSH's Guidelines on Occupational Safety and Health for Design, Inspection, Testing and Examination of Local Exhaust Ventilation Systems.

Our LEV inspection scope covers:

• Inspection of the local exhaust ventilation system as specified under the relevant guidelines
• Determination of capture or face velocity
• Determination of hood static pressure
• Determination of duct static pressure along the ducting system
• Determination of hood velocity pressure and transport velocity
• Determination of air cleaner's efficiency
• Determination of fan's capacity and efficiency

Hearing loss from noise doesn't happen in one dramatic moment — it builds up quietly, exposure after exposure, until the damage is permanent. Occupational hearing loss, including acoustic trauma and noise-related hearing disorders, is one of the most common and most preventable workplace injuries worldwide, and excessive workplace noise remains a leading avoidable cause of permanent hearing impairment globally.

To help workplaces identify and manage noise-related risks, the Eurofins network of companies in Malaysia carries out Noise Risk Assessment (NRA) with in-house NRA competence, covering:

• Area noise monitoring and personal noise exposure monitoring, using instruments approved to International Electrotechnical Commission (IEC) standards
• Tabulating, interpreting, and comparing monitoring results against the exposure limits set under the Noise Exposure Regulations 2019
• Assessing the adequacy of existing noise control measures at the workplace
• Recommending practicable noise reduction measures — engineering controls, process or design changes, administrative controls, and personal hearing protection
• Recommending follow-up programmes to further reduce employees' risk of noise-induced hearing loss

Hearing doesn't recover once it's lost to noise exposure. Audiometric testing provides employers with a clear, measurable way to track employee hearing health over time.

A proper audiometric testing programme goes beyond a one-off test. It includes a baseline audiogram, annual follow-up audiograms, employee education on hearing protection, and clear follow-up procedures whenever results show a change. Under the Occupational Safety and Health (Noise Exposure) Regulations 2019, employers must provide audiometric testing at no cost to any employee exposed to noise at or above the 85 dB action level, measured as an 8-hour time-weighted average. Where a noise risk assessment confirms an employee's exposure exceeds the regulated limit, annual audiometric testing becomes mandatory.

Eurofins Environment Testing Malaysia operates a DOSH-approved mobile audiometric testing centre, bringing certified hearing testing directly to the workplace for greater convenience and compliance.

A workstation that looks safe on the surface can still be quietly causing strain — a chair set too low, a monitor positioned awkwardly, a repetitive reach that adds up over months. Ergonomic assessment evaluates how well a job actually fits the worker, examining tasks, equipment, and the work environment to spot these hazards before they turn into injury.

The assessment takes a close look at how the job is actually performed — posture, tool and equipment use, force, repetition, and other physical demands involved in the task. This usually includes observing the worker completing their tasks, reviewing the work environment and conditions, and checking any relevant medical or injury records.

From there, the assessor recommends practical improvements to reduce the risk of musculoskeletal disorders (MSDs) — this could mean adjusting workstation setup, modifying tools, introducing safer work practices through training, or recommending personal protective equipment where needed.

Ergonomic assessments can be carried out by occupational therapists, ergonomists, or other qualified health and safety professionals, and are typically performed periodically to keep the workplace safe and ergonomic as conditions and tasks evolve.

An OSH Coordinator is only as effective as the training behind them. Eurofins Malaysia's HRDF-registered OSH Coordinator Training equips coordinators with the knowledge and skills to identify, assess, and manage workplace hazards — covering safety protocols, legal requirements, and hazard control measures needed to implement effective safety strategies across the organisation.

Under the Occupational Safety and Health Act 1994 (Act 514), employers carry legislative responsibility for the safety, health, and welfare of their workforce. This training helps organisations meet that responsibility by building in-house awareness and capability to prevent occupational injuries and diseases, particularly around chemical safety — where properly trained employees can recognise hazards, apply the right controls, and protect both themselves and company assets from unwanted incidents. Well-prepared coordinators also form a critical part of a company's chemical spill emergency response team.
