Do you work in earthmoving or a related field? If so, you’re probably familiar with all sorts of machinery and earthmoving processes. As summer approaches and the weather gets warmer, it’s incredibly important to follow proper heat management procedures. This is a core component of workplace health and safety and wellbeing for operators, and machines require proper heat management as well. This helpful article will cover the topic in detail, so continue reading to learn more about this incredibly valuable subject.
Summer Risks on Site
There is a range of risks related to heat on-site, to which machine operators can be exposed. We’ll list these in more detail now.
The first risk is extreme heat caused by the summer weather. Working in heat can be incredibly risky for operators due to heatstroke, and as such, most worksites will close for the day if the temperature reaches a certain point. Another major risk is the radiant heat emitted by machines, to which operators can be exposed. Engines run hot, and this can be compounded by the heat of the day. Another risk is exposure to dust from the worksite, which can cause respiratory illnesses and exacerbate conditions in individuals with pre-existing respiratory issues.
How to Protect Operators
Employers of earthmoving operators can take several steps to protect them from these risks. One essential element of protection is ensuring an adequate hydration plan is in place. Ensuring that operators stay hydrated is an excellent mitigation against heatstroke. As an operator, you may want to consider electrolyte drinks, such as sports drinks, to replace the fluid and electrolytes lost through excessive sweating.
Another way to protect operators is to implement rest and shade rotations, where operators have a chance to take a break and seek shade. In contrast, another operator who has been resting in the shade takes over the operation of a machine.
Proper Personal Protective Equipment, or PPE, is essential too. Hats, sunglasses, and dusk masks are all required here.
Also, recognising the signs of heat stress and heatstroke early is a major aspect of heat safety and management. Heat stroke symptoms include a high body temperature (above 40∘°C), hot and dry or sweaty skin, confusion, and rapid pulse. Other signs include nausea, vomiting, throbbing headaches, dizziness, and loss of consciousness. It is a medical emergency that requires immediate cooling of the body and a call to emergency services.
Keeping Machines Cool
Part of heat management for machines in warm weather involves ensuring that the machines remain cool to operate correctly without overheating. Operators can perform cooling system checks, including inspecting the radiator, coolant levels, and the belt. Ensure that you clean the filters, monitor machine temperature, and park smart, such as in a shaded area away from direct sunlight. If your current fleet struggles in high temperatures, consider speaking with Zoomlion Australia or another leading OEM about machines specifically designed for Australian conditions.
Operating Practices in Heat
There are several operating practices that operators and earthmoving companies can follow to stay heat smart. During operation, operators should closely monitor temperature gauges and warning indicators. Machines that begin to overheat should be idled in a shaded area until the temperature returns to normal; then, they can resume operation. Avoiding long idling times and maintaining steady, moderate engine loads can help reduce internal heat buildup. Scheduling the most demanding work during cooler parts of the day, such as early morning or late afternoon, is an effective way to manage equipment strain and reduce the risk of heat exhaustion among operators. Also, avoid overloading machines and manage dusty environments adequately.
Site Setup for Hot Weather
There are several steps for site setup that you can follow to manage heat effectively. Consider erecting shade structures for operators to take breaks under, and have water points throughout the site so workers can stay hydrated. Ensure all first aid stations are ready, and have trained and designated first aid officers on site. Additionally, ensure that all communication systems, such as walkie-talkies and radios, are fully operational in the event of an emergency.
Maintenance Schedule Tweaks
Finally, you may want to consider some maintenance schedule tweaks to ensure machines stay operational in the heat. Up the frequency of machine inspections to ascertain that machines are operating in the hotter conditions. Perform fluid checks such as coolant and oil levels, and inspect tyres and tracks to ensure that they are not worn out. Also, you’ll want to keep accurate records of maintenance and repairs for warranty and compliance purposes.
In Summary
This helpful article covers earthmoving in the summer and provides guidance on heat management for machines and operators. We covered summer risks on-site, including how to protect operators and keep machines cool. Furthermore, we examined operating practices in hot weather, adequate site setup, and adjustments to the maintenance schedule.
