Occupational hygiene consultancy questions clients commonly ask.
These concise answers help organisations understand when occupational hygiene support is required and what an assessment usually involves.
What is occupational hygiene?
Occupational hygiene is the discipline of anticipating, recognising, evaluating and controlling workplace health hazards such as dust, chemicals, noise, heat, biological agents and other environmental stressors.
When should a company conduct exposure monitoring?
Exposure monitoring is useful when workers may be exposed to hazardous substances or physical agents, when new processes are introduced, when complaints arise, or when organisations need evidence to support risk control and compliance.
What is the difference between personal and area monitoring?
Personal monitoring measures exposure at the worker’s breathing zone or body location, while area monitoring measures conditions at fixed locations. Both can be useful depending on the assessment objective.
Does IEH provide occupational hygiene services in Singapore?
Yes. IEH provides occupational hygiene consultancy, exposure assessment, workplace monitoring, programme development and professional deployment support for organisations in Singapore and the region.
What will the occupational hygiene report include?
A typical report includes the assessment objective, workplace observations, sampling strategy, monitoring results, interpretation, risk findings and recommendations for exposure control.
Can IEH support both assessment and implementation?
Yes. IEH can support clients beyond measurement by helping develop control strategies, occupational hygiene programmes, training, follow-up inspections and ongoing monitoring plans.
