Introduction
Workplace safety is not limited to preventing accidents. Employees can also face health hazards caused by repeated or prolonged exposure to dust, fumes, chemicals, noise, heat, vibration and unsuitable working conditions. These hazards may not always produce immediate symptoms, making them harder to recognise without systematic assessment.
Industrial hygiene provides a structured approach to identifying, evaluating and controlling workplace health hazards. By examining workplace conditions and monitoring potential exposures, organisations can make informed decisions that improve employee health and working conditions.
What Is Industrial Hygiene?
Industrial hygiene, also known as occupational hygiene, focuses on anticipating, recognising, evaluating and controlling environmental factors that may affect worker health.
Chemical Hazards
Chemical hazards may include gases, vapours, solvents, fumes and other substances generated or used during workplace operations.
Physical Hazards
Physical hazards can include excessive noise, heat, vibration and inadequate illumination. These conditions may affect workers when exposure is not properly assessed or controlled.
Ergonomic Hazards
Ergonomic hazards can result from repetitive tasks, awkward postures, forceful movements or poorly designed workstations.
Why Is Industrial Hygiene Important?
Many workplace health hazards are not immediately visible. A facility may appear well maintained while workers are still exposed to airborne contaminants, excessive noise or other environmental stressors.
A structured industrial hygiene assessment can help organisations identify potential hazards and determine whether further monitoring or corrective action is required.
Identify Potential Exposures
Workplace surveys can help identify areas where employees may be exposed to dust, fumes, noise, heat, chemicals or other hazards.
Evaluate Workplace Conditions
Monitoring provides information about exposure conditions and helps organisations understand the nature and extent of potential workplace risks.
Support Better Controls
Assessment findings can guide decisions about engineering controls, administrative measures, work practices and personal protective equipment.
Common Workplace Health Hazards
Different industries can present different occupational health challenges. Manufacturing, construction, mining, pharmaceutical, chemical and petroleum environments may require specialised assessments.
Dust and Particulates
Dust can be generated through cutting, grinding, material handling, construction and other industrial processes. Monitoring can help identify areas where airborne particulate exposure may need to be addressed.
Fumes and Vapours
Industrial processes may produce fumes or vapours from chemicals, solvents, welding and other activities. Workplace exposure monitoring can help determine whether additional controls are necessary.
Noise
Noise is a common physical hazard in industrial environments. Area noise monitoring, noise mapping and personal dosimetry can help organisations understand noise exposure across different work areas and tasks.
Heat Stress
Employees working in hot environments or performing physically demanding activities may be exposed to heat stress. Monitoring workplace conditions can help identify areas requiring additional controls.
Vibration
Depending on the tools and machinery used, workers may experience hand-arm or whole-body vibration. Assessing vibration exposure can help identify potential risks associated with specific equipment or tasks.
How Industrial Hygiene Assessments Work
A systematic assessment generally moves from identifying potential hazards to evaluating exposure and determining appropriate controls.
Workplace Survey
The process can begin with a walkthrough survey. This helps identify processes, materials, equipment and areas that may require further investigation.
Monitoring and Analysis
Depending on the workplace, monitoring may cover dust, fumes, noise, heat stress, vibration, illumination, indoor air quality or other environmental parameters.
Evaluation
The collected information can then be reviewed to understand exposure conditions and identify areas where workplace improvements may be needed.
Control Measures
The final objective is to reduce or control exposure. Depending on the hazard, organisations may consider engineering controls, changes to work practices, administrative measures or appropriate PPE.
Indoor Air Quality and Workplace Health
Indoor air quality is another important area of workplace environmental assessment, particularly in enclosed or air-conditioned facilities.
Poor indoor air quality can affect comfort and wellbeing and may be associated with symptoms such as headaches, fatigue, eye irritation, throat irritation and breathing discomfort.
What Can Be Monitored?
Depending on the facility, assessments may include temperature, relative humidity, carbon dioxide, carbon monoxide, oxygen, particulate matter, total volatile organic compounds and biological parameters.
A building survey can also examine air-conditioning and air-handling systems to identify potential sources of indoor air quality concerns.
Ergonomics and Workplace Health
Ergonomic conditions can affect workers when tasks involve repetitive movements, awkward postures, excessive force or unsuitable workstation arrangements.
Ergonomic Assessment
An ergonomic assessment can review workstations and job activities to identify potential physical risks. Depending on the findings, organisations may consider workstation changes, improved work methods, task variation, job rotation or better placement of tools and equipment.
Controlling Workplace Health Hazards
Once workplace hazards have been identified and evaluated, organisations need appropriate control measures.
Engineering Controls
Engineering controls can address hazards through equipment design, ventilation, isolation or process modifications. These measures can reduce exposure at its source.
Administrative Controls
Administrative controls may include work procedures, scheduling, training, restricted access and other practices designed to manage exposure.
Personal Protective Equipment
PPE can provide an additional layer of protection where hazards cannot be completely eliminated through other controls. The selected PPE should be appropriate for the specific exposure and task.
Industries That Benefit From Industrial Hygiene
Industrial hygiene services can be relevant to many sectors.
Manufacturing
Manufacturing facilities may require assessment of dust, fumes, noise, chemicals, heat and ergonomic conditions.
Construction
Construction activities can involve dust, noise, vibration, heat and chemical exposures across changing work locations.
Pharmaceutical and Chemical Operations
These environments may involve specialised exposure considerations related to chemicals, processes and workplace conditions.
Mining and Heavy Industry
Mining and heavy industrial environments may require monitoring for dust, noise, vibration, heat and other occupational hazards.
