Every DOSH occupational health assessment your factory needs — chemicals, ventilation, noise, ergonomics, indoor air and psychosocial — conducted by registered assessors and managed through to controls by one team.
Overview
The health side of safety and health
Most factory compliance programmes are strong on safety — guarding, permits, fire, machinery — and thin on health. Yet a large share of DOSH's regulations deal with health: chemical exposure under USECHH 2000, noise under the Noise Exposure Regulations 2019, indoor air under the ICOP 2010, and ergonomic and psychosocial risks under the general duty in section 18B of OSHA 1994.
Many of these assessments must be carried out by someone registered with DOSH for that specific work — an assessor, a hygiene technician, an occupational health doctor. Sorting out which applies, who can do it and when it is next due is where many sites lose track.
ProSafe handles that. Registered assessments are conducted by the appropriately DOSH-registered person; ProSafe scopes them, schedules them, and stays to implement the controls — for factories across Johor Bahru, Pasir Gudang, Tebrau, Senai, Kulai and Iskandar Puteri.
One point of contact
Instead of separate vendors for CHRA, noise, LEV and IAQ — each with its own report format and due dates — one register of every occupational health obligation on your site, and one team accountable for keeping it current.

Is this you?
- Your HIRARC names health hazards— chemicals, noise, manual handling — with no assessment behind them.
- You have several assessmentsfrom different vendors, on different cycles, and no single view of what is due.
- A DOSH inspection or customer auditasked for occupational health records you could not produce.
- Reports exist but recommendations do not— the assessments were done and the controls never followed.
- You are opening a new site or lineand want the health assessments planned in from the start.
How We Help
Registered work, managed properly
We are straightforward about who does what. Each registered assessment is conducted by a DOSH-registered assessor, hygiene technician or occupational health doctor appropriate to it, and your report carries that person's name and registration number.
What ProSafe adds is everything around the assessment: working out which apply to your site, preparing the data before anyone arrives, combining site visits where it makes sense, and — most importantly — implementing the recommendations so the next assessment shows improvement rather than the same findings.
Every obligation goes into one register with its due date, so CHRA reviews, LEV tests, audiometric retests and IAQ reassessments are arranged before they lapse rather than discovered after.

FAQ
Industrial hygiene — common questions
What is industrial hygiene?
Industrial hygiene is the part of occupational safety and health concerned with the workplace environment's effect on health — chemicals, noise, ventilation, air quality, ergonomics and psychosocial factors. In Malaysia most of it is set by regulations and codes under OSHA 1994, and many of the assessments must be done by people registered with DOSH.
Does ProSafe hold the DOSH registrations itself?
Registered assessments are conducted by a DOSH-registered assessor, hygiene technician or occupational health doctor appropriate to each one. ProSafe scopes the work, manages the engagement and turns findings into controls on your floor. Your reports carry the name and registration number of the registered person who conducted the assessment.
Which assessment should we start with?
Usually with whatever your HIRARC and your processes point to. Sites using solvents, adhesives or other chemicals hazardous to health start with a CHRA. Loud processes point to a Noise Risk Assessment. Heavy manual handling points to an ergonomic assessment. A short site walk is normally enough for us to tell you which apply and in what order.
Is psychosocial risk assessment required?
Section 18B of OSHA 1994 requires employers to assess the risks their work creates, and DOSH's Guidelines on Psychosocial Risk Assessment and Management at the Workplace 2024 set out how psychosocial risks — workload, job control and support — are expected to be assessed. The guidelines use a screening questionnaire, an employer checklist and a Psychosocial Trained Person to run the process.
Can these assessments be combined into one visit?
Often, yes. Walkthroughs, data collection and scheduling can be shared, and some measurements can be taken on the same production days. Each assessment still produces its own report by the appropriately registered person, but combining them reduces disruption and cost.
Environmental obligations under DOE — stack emission, effluent, boundary noise — are covered separately under environmental monitoring.
