Heatwaves as a work hazard.
admin • February 4, 2025
When there is a heatwave, it can introduce temperatures which are a new hazard not normally experienced in a workplace. As always, the employer must eliminate or minimise risks as far as reasonably practicable. That means that when conditions change, it’s time to do a risk assessment and put new controls in place.
There is no single ‘stop work’ temperature. Various factors need to be taken into account which include humidity, air flow and the type of work being performed.
Heatwave conditions create a work-related risk in the form of heat stress and fatigue. But there are various ways to control the risk. Things to consider may include:
- working in the cooler part of the day
- moving work to a different location
- limiting tasks which require higher physical effort during the hotter period
- changing work expectations and allowing workers to self-pace their work
- ensuring access to cool water - and rehydration electrolytes if required
- providing shade
- air conditioning or fans if possible
- ensuring workers are not working in isolation
- ensuring supervision is in place
- taking into account more vulnerable workers - for example those who may be young, pregnant, suffer an illness, etc
- training workers to ensure they understand the risk and how to recognise symptoms
- ensure first aid and medical assistance is available
Remember that the risk posed by heat is not just limited to outdoor workers. Indoor workers can be exposed to unsafe working conditions too - including high temperatures, thermal radiation and humidity.
As with all hazards - when considering what control to put in place, the usual hierarchy of control should be used – with elimination being considered first. If this can’t be done, then consider substitution, followed by isolation/ engineering controls, then administrative controls and finally PPE as the last option.
As always, the effectiveness of the controls should be monitored and reviewed.
Health and Safety Representatives (HSRs)s can be proactive in this area by consulting with the employer and attempting to resolve the risk. If there is an immediate risk to health and safety, then they can direct a cease work.
HSRs play an important role in ensuring a safe workplace – and this includes during heatwave conditions.
When Winter sweeps across Victoria, temperatures can drop sharply, especially in regional areas and early mornings. For outdoor workers, or those in cold storage and refrigerated environments, these conditions aren’t just uncomfortable, they can be dangerous if not managed properly. Working in a cold environment can lead to: Hypothermia : when body temperature drops below safe levels. Frostbite : damage to skin and tissue from freezing. Reduced dexterity : making tasks harder and increasing risk of incidents. Slips and falls : from ice, frost, or wet surfaces. Fatigue : as the body works harder to stay warm. Increase in prevalence of other conditions: such as arthritis and bronchitis. Under the Victorian Occupational Health and Safety Act 2004 (The Act), employers must provide a safe working environment. This includes: Identifying cold-related hazards. Implementing control measures to eliminate or reduce the risk as far as reasonably practicable. Follow a risk management process in relation to the hazard. Consult with your workforce throughout the process. When you have identified that you have a cold hazard in your workplace, you must control the risk as far as reasonably practicable. As, always this means working through the Hierarchy of Control from top to bottom. Here are some ways you could think about controlling the cold hazard in your workplace: Eliminate: Think about changing work scheduling if weather is extreme. Substitute: Think about whether you could move the work to another location. Isolate: Protect the workers from the cold, for example by providing shelter. Engineer: Can you provide heating or insulation in this work situation? Administrative controls: Could include changes to the workflow or rosters. Training must be provided, including training in the signs of cold stress and treatment. PPE: Such as weatherproof clothing, hats, face covers, boots, and allowing for drying or replacement of gear. Don’t forget that, under The Act, Consultation must be undertaken at every step of the process. Monitoring of the controls must also occur, especially as conditions change. Frosts and wind chill factor should be taken into account, as well as seasonal or unexpected weather changes. Cold conditions in Victoria can be managed with the right planning, clothing, and awareness. Employers and workers share the responsibility to ensure everyone stays safe, warm, and healthy through the winter months. Health and safety representatives are a key part of the co-operative process required to create safe workplaces.

If you’ve spent any time on a Victorian farm, you know the quad bike is as common as the gum tree. It’s the workhorse that gets you from the dairy shed to the back paddock in minutes. But while ATVs save time and effort, they also carry serious risks, especially when safety takes a back seat. Studies have found that rollover and crush protection on quad bikes is saving lives, particularly in Victoria, where farm fatalities have been steadily declining. Yet, despite these improvements, quad bike incidents remain one of the leading causes of death and injury on Australian farms. Quad bikes (also called ATVs) are incredibly useful for mustering livestock, carrying supplies, and navigating rough terrain. But their stability can be deceptive, with uneven ground, high speeds, or heavy loads easily leading to rollovers. In Victoria, WorkSafe data shows that most fatal incidents involve the bike overturning and trapping the rider. Since October 2021, the national quad bike safety standard has required: Operator Protection Devices (OPDs) to reduce crush injuries in rollovers. Minimum stability requirements for new models. Warning labels about rollover risks. Victoria has been ahead of the curve, with strong farm safety campaigns and subsidies to help farmers retrofit OPDs. Practical Safety Tips for Victorian Farmers Always Wear a Helmet . Even at low speeds, head injuries can be fatal. Fit a Crush Protection Device . These can prevent you from being pinned under the bike. Match the Bike to the Job . Don’t overload or tow beyond the manufacturer’s limits. Ride to the Conditions . Slow down on slopes, wet ground, or unfamiliar tracks. Never Carry Passengers . Unless the ATV is specifically designed for more than one rider. Training Matters . Enrol in an accredited ATV safety course to sharpen your skills and make sure all operators have adequate training to operate the vehicle. Don’t forget that the employer has a duty to provide information, instruction and training to ensure that employees can work safely. Review the terrain before undertaking the task . Some areas of the farm may need to be strictly off-limits for ATV use. Look at alternative options . Some farmers are switching to side-by-side vehicles (SSVs), whic h offer seatbelts and roll cages. While not risk-free, they can be safer for certain tasks, provided operators still follow safety protocols. ATVs are here to stay on Victorian farms, but so is the responsibility to use them safely. With the right equipment, training, and by keeping safety front-of-mind you can make sure your quad bike remains a tool, not a threat. If you’re a Victorian farmer, check your quad bike today. Is it fitted with a crush protection device? Are you wearing a helmet every ride? Safety isn’t just about compliance, it’s about coming home at the end of the day.
