Workplace drug and alcohol testing for Malaysian factories and plants
Machines don't forgive a slow reaction. Give your supervisors the breathalyzers, drug test kits and policy they need to keep every shift fit for work, from the first clock-in to the last.

Testing equipment
for every shift and site
Choose the method that suits each testing situation. Many plants use more than one.
Breath alcohol testing
Wall-mounted breathalyzers at the entrance test each worker in seconds as they arrive. Portable units suit spot checks on the floor. Every unit is certified to Australian Standard AS3547.
Urine drug testing
MDA-registered UDAT kits show use over a longer window. They suit pre-employment screening.
Saliva drug testing
Saliva kits detect recent drug use, from roughly the last 5 to 48 hours. They suit post-incident and reasonable suspicion testing.
Third-party on-site testing
Some employers prefer an independent provider to run testing days at the plant. We can advise on what to look for in a provider and supply the same certified equipment for your own team.
Which manufacturers should
test for drugs and alcohol?
Any site where an impaired worker could hurt themselves or others. That includes:
- Factories and assembly plants
- Food and beverage producers
- Electronics and semiconductor manufacturers
- Chemical, rubber and plastics plants
- Steel, metal and fabrication works
- Manpower suppliers and contractors placing workers on site
The cost of
impairment on the factory floor
Impairment slows reactions and clouds judgement around moving machinery. A testing program helps you find the risk before it becomes an incident.
Machinery injuries
Presses, conveyors and cutting equipment leave no room for a delayed reaction.
Forklift and vehicle incidents
An impaired operator puts pedestrians, racking and stock at risk.
Next-day impairment
Alcohol from the night before can still affect workers on an early shift.
Product quality and recalls
Mistakes on the line can mean rework, contamination or a recall, especially in food production.
Lost production
An incident can stop a line, trigger an investigation and delay orders.
Failed customer audits
Many global buyers audit their suppliers' health and safety controls. A clear drug and alcohol program helps you pass.
What should a manufacturing drug and alcohol policy
contain?
A clear policy tells workers what is expected, when they will be tested and what happens after a non-negative result. Add impairment as a hazard in your HIRARC so testing links back to your risk assessment.
Pre-employment
Screen new workers and contractors before they start.
Pre-shift
Breath test machine operators, forklift drivers and other safety-critical workers before their shift.
Random testing
Test a share of workers on a schedule your policy sets, to deter use.
Reasonable suspicion
Test when a supervisor sees signs of impairment.
Post-incident
Test after any injury, near miss or equipment damage.
Return to work
Set clear conditions for a worker returning after a positive result or treatment.

Frequently asked
questions
Still unsure? Talk to our team and we'll help you find the right testing approach for your plant.
Can a factory test workers for drugs and alcohol in Malaysia?
Many employers test under a written policy that workers know and agree to. OSHA 1994 and the DOSH Code of Practice support policies that prevent drug and alcohol problems at work. Check your employment contracts with your HR or legal adviser.
How do we test a whole shift without slowing the line?
A wall-mounted breathalyzer at the entrance tests each worker in seconds. Portable units cover spot checks on the floor.
What happens after a non-negative drug test?
Follow your policy. Usually the worker is stood down from safety-critical work and the sample goes to an accredited laboratory for confirmation.
Do you carry out testing at our plant?
No. We supply the equipment and advise on your policy and testing process, so your own team or your chosen provider can run the tests.
How often do workplace breathalyzers need calibration?
Every 12 months. We calibrate at our local office and remind you when it is due.
