Pumping flammable liquids is an activity that poses considerable risks both to people and the environment. Rigorous adherence to safety procedures is essential.

Our industrial cleaning specialists describe the various stages involved when pumping flammable liquids, as well as the grounding procedures necessary to minimize the risk of fires or explosions.

Pumping flammable liquids: what it involves

Pumping flammable liquids is a common operation within many industries, including the petrochemical, chemical and energy sectors.

It consists of transferring flammable liquids, such as gasoline, diesel, fuel oil, kerosene, or others from one container to another. For example, from a tanker truck to a service station or from a storage tank to another tank.

Hazardous materials transportation requires great care and vigilance, as the risks of fire and explosion are significant. It is always necessary to use special pumps equipped with safety systems including temperature, pressure and grounding sensors.

Optimal conditions are also required for safe flammable liquid pumping, i.e. a dry, ventilated and well-lit environment, far from any source of heat or sparks. Storage containers and transfer hoses must be in good condition and leak-free, as any breach of a container can lead to a hazardous materials spill, which in turn can cause a fire or explosion.

Pumping flammable liquids: a step by step process

Pumping flammable products is a delicate procedure. Following precise steps is essential to guarantee safety. Professionals respect a certain continuity to ensure efficiency and limit risks.

1. Preparing  

Before beginning to pump, prepare equipment and verify that all safety regulations are being met. Equipment can include:

- Pumps

- Pipes

- Containers

- Measuring tools.

Make sure that everyone involved is properly trained in plant safety procedures and informed of all risks associated with pumping flammable products.

2. Installing the pumping equipment

Pumps and hoses must be installed properly to prevent leaks. Make sure that hoses are compatible with the specific liquids that will be pumped, and that they are free of cracks, dents or other damage.

3. Implementing grounding procedures

Transfer hoses and containers must be grounded to eliminate the risk of static electricity and prevent sparks from forming while pumping flammable liquids. Everyone involved should also wear personal protective equipment such as antistatic shoes, gloves and flame resistant clothing, or respiratory protective equipment.

4. Controlling the flow

Flow rate should be controlled at all times and adjusted according to the characteristics of the liquid being transferred and equipment capacities, to avoid overpressure and splashing. It is also important to monitor the pressure of hoses and containers to detect any anomalies.

5. Cleaning the equipment

After the operation is complete, clean equipment thoroughly to remove all flammable residue. Proper cleaning is essential to avoid contamination and fire hazards. For optimal efficiency and safety, hire a professional industrial cleaning team when it’s time to handle hazardous materials. 

Pumping flammable liquids: grounding procedures

When pumping flammable products, there is a high risk that static electricity will create sparks leading to explosions. Earthing or ‘grounding’ is a crucial step which greatly reduces the risk of fire or explosion.

Remember that grounding procedures must be followed strictly by all personnel involved in the pumping operation. The health effects of toxic chemicals can be irreversible and any violation of these procedures can result in serious and dangerous consequences.

Connect transfer pipes and containers to the ground

All equipment used for pumping flammable products, including transfer hoses and containers, must be grounded to dissipate static electricity and prevent sparking.

Check the quality of the connections

Check the quality of ground connections before beginning the operation: make sure all ground connections are properly secured and all grounding cables are in good condition.

Avoid sources of static electricity

It is essential to avoid any potential sources of static electricity, such as friction between transfer hoses and containers, electrostatic discharge or sparks. Use special equipment such as metal or stainless steel transfer hoses, high quality grounding cables, grounding clamps, etc.
