Alcohol and drugs can affect a person’s ability to work safely. This includes medicines that are prescribed or over-the-counter.
As a person conducting a business or undertaking, you have a duty to keep workers and your workplace safe.
Duties relating to drugs and alcohol
Everyone in the workplace has WHS duties under the model WHS Act.
You have specific duties if you are:
a person conducting a business or undertaking (PCBU)
a principal contractor
a designer, manufacturer, importer, supplier and installer of plant, substances or structures
All workers have a duty to take reasonable care for their own health and safety and not adversely affect the safety of others.
As a PCBU, you must manage health and safety risks. This might include setting specific policies for the use of drugs and alcohol.
As a PCBU, you must, so far as is reasonably practicable:
ensure the health and safety of workers and others at your workplace
consult with workers who carry out work for the business or undertaking and who are (or are likely to be) directly affected by a health and safety matter, and
consult cooperate and coordinate activities with all other relevant duty holders.
be fit and well enough to do their job
not be under the influence of alcohol or drugs
not use alcohol or illegal drugs while at work.
Drug and alcohol limits
There’s a legal blood alcohol level in some jobs, including road and rail transport, maritime and mining occupations. The law may prohibit a worker from being affected by any drugs – legal or illegal.
Drug and alcohol testing
Some companies have policies to test their workers for alcohol and illicit substances, particularly if a worker could kill or seriously injure themselves or someone else.
