Drug and alcohol testing for Malaysian construction sites
Cranes, scaffolds, excavators and live power tools leave no room for impaired judgement. Give your site managers the breathalyzers, drug test kits and policy they need to keep every worker, subcontractor and visitor fit for work.

Testing equipment
for site gates and safety offices
Choose the method that suits each testing situation. Many sites use more than one.
Breath alcohol testing
Wall-mounted breathalyzers at the site gate test each worker in seconds as they arrive. Portable units suit spot checks on the scaffold or in the site office. 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 and site induction.
Saliva drug testing
Saliva kits pick up recent drug use, roughly the last 5 to 48 hours, so they fit post-incident checks and reasonable suspicion testing on site.
Third-party on-site testing
Some employers prefer an independent provider to run testing days on site. We can advise on what to look for in a provider and supply the same certified equipment for your own team.
Which construction businesses
should test for drugs and alcohol?
Any worksite where an impaired worker could injure themselves, a colleague or the public. That includes:
- Main contractors and developers
- Civil, infrastructure and highway works
- Building and high-rise construction
- Steel, scaffolding and formwork contractors
- Crane, hoist and heavy equipment operators
- Subcontractors and manpower suppliers placing workers on site
The cost of
impairment on a construction site
Impairment slows reactions and clouds judgement around cranes, scaffolds and moving plant. A testing program helps you find the risk before it becomes an incident.
Falls from height
Scaffolds, roofs and open edges leave no room for a slow reaction or poor balance.
Plant and vehicle incidents
An impaired operator puts workers on foot, and everyone near the excavator or crane, at risk.
Next-day impairment
Alcohol from the night before can still affect workers on an early start.
Work stoppages and delays
A serious incident can stop work on site, prompt an investigation and delay handover.
Lost tenders
Developers and principals expect contractors to show how they manage drug and alcohol risk. Weak controls can cost you the next bid.
Higher insurance costs
A poor safety record raises insurance premiums and weakens claims.
What should a construction 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. Cover your own employees, subcontractors and their crews, and any visitor or delivery driver who enters a restricted work zone. Add impairment as a hazard in your HIRARC so testing links back to your risk assessment.
Pre-employment and site induction
Test new workers before they start and record the result.
Pre-shift
Breath test crane operators, scaffolders and other safety-critical workers before they start work.
Random testing
Test a random share of workers on a schedule set in your policy, to deter use on site.
Reasonable suspicion
Test when a site supervisor or foreman sees signs of impairment.
Post-incident
Test after any accident, near miss or equipment damage.
Return to work
Agree clear conditions for a worker coming back after a positive result or treatment.

Frequently asked
questions
Still unsure? Talk to our team and we will help you find the right testing approach for your sites.
Can a construction company test workers for drugs and alcohol in Malaysia?
Many employers do, under a written policy that workers know about and accept. OSHA 1994 and the DOSH Code of Practice back policies that tackle drug and alcohol problems at work. Check your contracts with your HR or legal adviser.
Do subcontractors need to follow our policy?
Yes, if your subcontract says so. We help you write the clause in a consultation.
Which test suits a busy site gate?
Breath tests take seconds, so they suit the gate. Saliva kits suit post-incident and reasonable suspicion checks.
Can one breathalyzer serve a whole site?
Yes, with a fresh mouthpiece for each test. For several sites, Andalink collects every result in one dashboard.
Do you carry out testing on our sites?
No. We supply the equipment and help with your policy and process, and your own team or a provider of your choice runs the tests.
How often does a site breathalyzer need calibration?
Every 12 months from the date of purchase. Our local office calibrates it and reminds you when it is due.
