We have experienced a scorching summer so far this year and we are only in July. Weather forecasters say that the number of days with temperatures over 30⁰C has trebled in recent years. The hot weather has an impact on both the forklift trucks and their operators. Here we look at the possible risks and how to mitigate them.

Effect of heat on Forklift Truck Operators

• The sun can heat up the forklift truck metal structure to such an extend to cause superficial burns to naked skin. It will also heat up the steering wheel, seat and the controls. To protect the operator, whenever possible keep the forklift truck out of direct sunlight
• Exposure to sun for prolonged period could cause sun burn. Wear UV protective clothing and apply suncream with at least factor 50 UV protection
• Not drinking enough liquids in hot weather may cause dehydration. Ensure that the forklift truck operators drink plenty of liquids. Recommend at least two litres per day. Avoid excessive drinks containing caffeine like tea and coffee as it acts as a diuretic. Signs of dehydration include dark-coloured urine, fatigue, dizziness, extreme thirst, and confusion. Severely dehydrated people need immediate medical treatment.
• Another risk is heatstroke. Symptoms include headaches, nausea, increased heart rate, confusion and loss of consciousness. To prevent heatstroke, if possible, work early in the morning or later in the day when the temperatures are lower.
• Hot weather often drains peoples’ energy and increases the chances of operator error. Forklift operators should have frequent breaks, preferably in an air-conditioned room.

Effects of Heat on Forklift Trucks

• Engine overheating is a key risk in hot weather for forklift trucks, especially those that run on internal combustion engine. Ensure that the radiator or cooling system is clean and functioning properly. Perform regular maintenance checks including coolant levels.

• Hot temperatures shorten battery life, speed up discharge rates, and reduce overall efficiency especially if you’re not following a proper charging routine. Also, you may have air conditioning or fans on which drain the battery. Test and monitor batteries regularly and follow the manufacturer’s charging guidelines and avoid overcharging.

• Hydraulic fluids break down faster in heat and lose the ability to lubricate and cool moving parts causing increased friction, sluggish lift performance, and premature wear on hoses and seals. Change and top-up hydraulic fluids regularly.

• Tyres expand in the heat especially pneumatic ones. With heavy loads and rough surfaces creates a higher risk of blowouts, accelerated tread wear, and poor traction. Check tyre pressure and condition daily and adjust for heat expansion. Replace worn tyres.

Take the effects of hot weather on the forklift trucks and its operators seriously. Regular breaks and maintenance of the forklift truck will ensure the smooth running of your operation.

Ruth Wallace of Wallace Forklift Training London says “Forklift truck operators, supervisors and managers should be trained to cope with high temperatures and be able to recognise the symptoms caused by heat to avoid any incidents”.
