Control combustible materials
During transportation, there must be no flammable items around the oil tanker to reduce the risk of fire. At the same time, regularly inspect the oil tankers and related equipment to ensure they are in good condition and prevent safety accidents caused by equipment failures.
In addition, it is essential to strictly prevent the oil storage containers of oil tankers from overflowing. During the loading and unloading of oil products by oil tankers, strict monitoring is necessary. Once any leakage, overflow, dripping, seepage or overflow of oil is detected, immediate measures should be taken to clear and handle the situation. After unloading the goods, it is strictly prohibited to pour oil stains, oil sludge, waste oil, etc. into the sewer for discharge. These wastes should be collected at designated locations and properly disposed of. All flammable materials must be removed near buildings such as oil tanks, warehouses, pump rooms, oil dispensing rooms and oil blending workshops to reduce the risk of fire. When maintaining and servicing oil tankers, used items such as oil-stained cotton yarn, oil-stained cloths, oil-stained gloves, and oil-stained paper should be placed in covered iron drums outside the workshop and cleaned up in a timely manner.
Cut off the source of fire
Cutting off the source of fire is the key. No smoking, open flames or any other source of fire are allowed in the oil depot and the operation area. It is strictly prohibited to bring matches, lighters or other sources of fire into the oil depot, oil storage area and receiving and dispatching operation area. The flow of fire sources and open flame operations must be strictly controlled. Smoking and open flames are strictly prohibited in the oil depot. If open flames must be used for repair work, it is necessary to report to the relevant departments for review and approval, and take necessary safety precautions. Before cars and tractors are parked in the warehouse, fireproof covers must be added to the exhaust pipe openings. After parking, the engines should be immediately turned off. It is strictly prohibited to repair vehicles or start engines inside the warehouse. When railway locomotives enter the depot, isolation cars should be attached, the ash box guards should be closed, and they must not stay in the depot for furnace cleaning or non-operation areas. When oil tankers dock at the wharf, the use of open flames is strictly prohibited, and it is forbidden to carry fire sources onto the ship.
Prevent electric sparks
It is also necessary to pay attention to preventing electric sparks from causing combustion and explosion. Use explosion-proof equipment to avoid sparks caused by wire faults. Electrical equipment used in oil depots and workplaces must be explosion-proof. Installation must comply with safety requirements, and there must be no broken insulation, exposed wires or short circuits in the wires. There must be no high-voltage power lines crossing over the oil depot. The distance between the oil storage area and the light oil barrel warehouse and the power lines must be more than 1.5 times the length of the electric pole. The railway tracks leading into the oil depot must be equipped with insulating partitions before the entry port to prevent external power from flowing into the oil depot through the tracks and generating electric sparks.
Prevent sparks from metal friction
In addition, it is also necessary to prevent sparks caused by metal friction. Avoid sparks caused by metal friction in the work area and pay attention to the requirements for tools and footwear. Strictly enforce the regulations on entry and exit from the depot and operation areas. It is prohibited to enter the oil depot wearing shoes with nails or shoes with iron handles, and it is even more forbidden to climb oil tanks, oil tankers, etc. Do not use iron tools to strike out the container LIDS. When opening the LIDS of large barrels and tank trucks, copper wrenches or alloy wrenches should be used. In the warehouse, metal containers should be prevented from colliding with each other, and oil drums without gaskets must not be rolled on the cement floor. During the unloading operation of oil tankers, it is necessary to prevent the unloading swan neck pipe from colliding with the tanker’s opening or the oil tanker’s hatch when it is inserted or pulled out. Wherever there is oil and gas, iron metals must not be struck.
Prevent the accumulation of oil vapor
It is also necessary to pay attention to preventing the accumulation of oil vapor from causing combustion and explosion. The storage containers should be well-ventilated to prevent the accumulation of oil and gas. Unwashed oil drums, oil tanks and other storage containers are strictly prohibited from being repaired or welded. After washing, the container should have its lid opened for ventilation before being ready for welding. If necessary, visual explosion should be carried out first. The light oil products stored in the warehouse in barrels should be inspected frequently. If any leakage is found, they should be replaced in time. The warehouse should be kept well-ventilated. In underground and cave oil tank areas, it is essential to strictly prevent oil leakage and install ventilation equipment to maintain good ventilation and avoid the accumulation of oil and gas.
Anti-collision and anti-leakage
Finally, during transportation, it is also necessary to pay attention to preventing collision and leakage. Improve the tank design, add safety devices, and reduce the risks of collision and leakage. Arrange the outer interfaces of the tank at the end head positions of the cylinder to reduce the risk of impact. Try to use built-in valves as much as possible to reduce impact. Leakage alarms should be installed at the concentrated parts of the inlet and outlet valves of tank trucks carrying highly hazardous and extremely toxic media. Install emergency leak-stopping devices to deal with the leakage of toxic media.
