A RECENT report presented by RMIT University addressed the legal concerns relating to staff working within smoky environments.

Amid thick bushfire smoke in cities including Canberra and Melbourne, employers need to consider their legal obligations in accordance with the ‘Federal Act of Parliament’.

Some have directed their workers not to turn up in order to avoid occupational health and safety risks. Among them is the Commonwealth Department of Home Services, which last week asked most of its staff to stay away from its Canberra headquarters for 48 hours.

Each state and territory have their own occupational health and safety laws.
However most line up with the so-called Model Act, intended to harmonise state laws.

Under section 17 it imposes on employers a duty to, so far as is reasonably practicable, ensure health and safety by eliminating or minimising risks.

This employer’s duty applies not only to its employees but also to other types of workers including independent contractors.

Meaning of ‘reasonably practicable”

Under the section 18 of the Model Act, “reasonably practicable” means that which is, or was at a particular time, reasonably able to be done in relation to ensuring health and safety, taking into account and weighing up all relevant matters

By themselves, these words aren’t much of a guide, so the Act includes examples of “relevant matters”, among them:

  • the likelihood of a hazard or risk occurring
  • the degree of harm that might result
  • what the employer knows or ought reasonably to know about the hazard or risk, and ways of eliminating, or minimising hazard or risk
  • the availability and suitability of ways to eliminate or reduce hazard or risk
  • the cost associated with available ways of eliminating or minimising the risk, including whether the cost is grossly disproportionate to the risk

Meaning of ‘likelihood’

Employers should make themselves aware of the risk of an air quality hazard. This can be achieved by checking the most up to date air quality index in the location on an environment protection authority website of the various states: NSW, Victoria, Queensland, South Australia, Western Australia, Tasmania, Northern Territory or ACT.

Asthma sufferers may be at greater risk

It is certainly arguable the likelihood of harm for indoor workers is much lower, especially if the air quality in their workplace is the same or even better than the air quality in their homes.

Employers should have up-to-date information about the health of their workers, especially those workers who have pre-existing conditions that might predispose them to harm from the smoke.

Among these would-be workers who have asthma or other respiratory disorders.

Special steps should be taken to protect them, taking into account their pre-existing conditions.

Meaning of ‘reasonably ought to know’

Employers should be checking up-to-date information on an environment protection authority website and on the website of Safe Work Australia.

It’s very likely law enforcers will presume the information on these websites constitute information the employer ought to have known in determining the appropriate action to take.

For example, it would be difficult for an employer to argue they didn’t know P2 rated face masks should be provided to workers when the Safe Work Australia website specifically mentions them as an appropriate way of eliminating or reducing air quality hazards.

Meaning of ‘availability of ways to reduce risk’

Safe Work Australia says employers should have in place measures to manage the risks to health and safety of working outdoors when air quality is reduced, including:

  • working indoors (where possible)
  • rescheduling outdoor work until conditions improve
  • ensuring buildings and equipment are functioning correctly and have not been affected by dust or debris
  • cleaning dust and debris off outdoor surfaces
  • providing personal protective equipment such as eye protection and correctly fitted P2-rated face masks.

Meaning of ‘cost of minimising hazard’

The cost of elimination or minimising hazard will be higher for some measures than others.

For example, it might cost more to direct workers to stay home than to provide face masks.

These costs need to be weighed up against the likelihood and degree of potential harm.

If the likelihood and degree of harm are high, it’s unlikely law enforcers will be particularly sympathetic to arguments about the cost. If you are experiencing smoke hazards in your business environment, please consider the above regulatory requirements.
