How Our Occupational Health Programme Works
A structured five-step programme that turns regulatory requirements into clear, auditable workforce health outcomes.
Baseline Assessment & Gap Review
We begin with a site and workforce assessment — identifying job categories, exposure risks, and regulatory requirements applicable to your operations under OSHA 1994.
Medical Surveillance Screening
Our Occupational Health Doctors conduct pre-employment, periodic, and exit medical examinations tailored to each exposure category — clinical, laboratory, and fitness-for-work assessments.
Specialised Testing
Audiometry for noise-exposed workers, drug & alcohol testing (UDAT), lung function testing, and other exposure-specific screening as required by regulation.
OHD Review & Certification
Results are reviewed by our DOSH-registered OHD, who issues medical certification and fitness-for-work recommendations — flagging any worker requiring follow-up or restriction.

Get StartedFrequently Asked Questions
What is an occupational health doctor (OHD)?+
An occupational health doctor is a registered medical practitioner who performs pre-employment, periodic, and return-to-work assessments, medical surveillance, and fitness-to-work evaluations. Our OHDs are Petronas Approved Medical Examiners (AME) with experience serving oil & gas and high-risk industries.
What does DOSH medical surveillance involve?+
Medical surveillance is the periodic health assessment of workers exposed to workplace hazards such as noise, chemicals, radiation, and heat stress. It includes clinical examinations, audiometry, spirometry, and biological monitoring, with DOSH-compliant reporting and trend analysis.
How does UDAT drug and alcohol testing work?+
UDAT (Urine Drug and Alcohol Testing) follows a strict chain-of-custody process — from sample collection to laboratory analysis and MRO-reviewed results — ensuring secure documentation and full compliance with corporate and national regulatory standards.
Can you conduct audiometry and fitness-to-work assessments on site?+
Yes. Our teams can deploy to your site with portable equipment for audiometry, spirometry, and fitness-to-work assessments, reducing downtime for your workforce while maintaining clinical standards.
What is audiometry and who needs it?+
Audiometry is a hearing test that identifies noise-induced hearing loss. Workers exposed to noise above the action levels under the OSH (Noise Exposure) Regulations 2019 require periodic audiometric surveillance as part of their medical surveillance programme.
How often is medical surveillance required?+
It depends on exposure and regulation. Workers exposed to noise and hazardous chemicals are typically assessed pre-employment, then periodically — commonly annually — with exit examinations on leaving exposure, in line with the OSH (Medical Surveillance) Regulations 2001.
Do you provide medical surveillance for oil & gas contractors?+
Yes. Our OHDs are Petronas Approved Medical Examiners and we run surveillance programmes for contractors across upstream, midstream, and downstream operations, including remote and offshore workforces.
How are medical records kept confidential?+
Medical records are managed under strict confidentiality in line with PDPA requirements — secured, access-controlled, and shared only with authorised personnel or as required by regulation.
