As a hazardous materials operation tool, the safety of tank trucks requires special attention. The main causes of fire accidents in tank trucks include non-compliant oil loading equipment, equipment failure, oil leakage, static electricity discharge, and human error. To effectively prevent tank truck accidents, the following aspects should be noted:

1. Static Grounding Cannot Be Ignored
- For tank trucks, static electricity mainly generates in pumps, filters, and pipelines. The static electricity generated by the tank truck loading system is much higher than that of ground pipelines.
- Relevant data shows that when pumping oil at a flow rate of 2500L/min through a 250m-long, 100mm-diameter underground pipe, the charge from the fuel nozzle is generally only [specific value missing], while the charge after passing through the tank truck exceeds [specific value missing]. These static charges mainly originate from the tank truck’s filter. Therefore, if the tank truck is ungrounded during loading and unloading operations, the tank body can carry a voltage of over 10kV.
Measures to address static electricity hazards:
① Connect the grounding wire before loading oil, and regularly check its integrity and whether the grounding resistance meets anti-static standards.
② During loading, the loading arm must extend to the bottom of the tank, with the nozzle kept about 15cm from the tank bottom. Strictly control the initial filling speed within 1m/s, and gradually increase the flow rate only after the outlet is submerged, but the maximum speed shall not exceed 4.5m/s to prevent static accidents caused by splashing.
③ After completing oil loading, wait for at least 5 minutes for the oil to stabilize before disconnecting the grounding. This is because the oil surface potential remains for several minutes due to oil flow inside the tank after loading.

2. Avoid Excessive Engine Temperature in Tank Trucks
- Regularly inspect the vehicle’s technical condition, focusing on safety-critical components. It is strictly prohibited to drive a faulty vehicle.
- In hot summer weather, monitor the water temperature gauge during driving, which generally should not exceed 95°C. This is particularly important when the vehicle is loaded or driving on mountain roads to prevent engine overheating.
- If the temperature is too high, park in a shaded area to cool down immediately. Open the engine hood to ventilate and dissipate heat. After the temperature drops, check whether the engine cooling system is short of water and the cause of overheating.
- If the coolant boils due to engine overheating or water shortage, do not turn off the engine immediately. Let the engine idle, and after the temperature drops, turn off the engine. Use a cotton yarn or gloves to open the radiator cap to prevent scalding from boiling coolant.
3. Strictly Prohibit Fatigued Driving
- Driving in hot summer weather or an overheated cab environment, with high temperatures and poor air circulation, makes drivers prone to fatigue. They often feel mentally tired, with blurred vision and 迟钝 (slow) thinking. Drowsiness is extremely likely during afternoon or midnight driving, even causing moments of memory loss. Forcing driving can lead to traffic accidents.
- On highways, the single road environment, low traffic interference, stable speed, and low noise and vibration frequency easily make drivers feel monotonous and drowsy, causing the “highway hypnosis phenomenon.”
4. Pay Attention to Tire Temperature
- Avoid prolonged driving in summer. Stop every two hours or after driving a certain distance to rest and check tire temperature.
- When finding that the tire pressure rises due to overheating, park the vehicle in a shaded area or under trees to allow the tires to cool and deflate naturally. Do not reduce tire pressure or temperature by deflating or splashing cold water. Additionally, avoid emergency braking and strictly prohibit overloading.
- Sudden tire blowouts during driving are a major hidden danger in summer safe driving. In case of a blowout, never suddenly turn the steering wheel in the opposite direction or step on the brake pedal in a panic. Instead, use the “gear grabbing” method to decelerate the vehicle by leveraging the engine’s braking effect. Before controlling the speed, do not risk using the service brake to park, as this may cause the vehicle to skid and lead to greater danger.
5. Emergency Measures for Steering Failure
- When the steering suddenly fails, if the vehicle and front road conditions allow maintaining straight driving, do not use emergency braking. Immediately release the accelerator pedal, shift to a lower gear to decelerate, and evenly and firmly pull the parking brake for assistance.
- When the speed significantly decreases, gently apply the brake pedal to stop the vehicle slowly and smoothly. If the vehicle has deviated from the straight driving direction and an accident is inevitable, decisively apply the brake pedal continuously to stop the vehicle as soon as possible, minimizing the stopping distance and impact force.
- While taking emergency measures, signal to other road users by turning on the hazard warning lights, high beams, honking the horn, or making hand gestures.
