Explosion risk assessment and written explosion protection document

What is the DOPV?

DOPV stands for "Explosion Protection Document". It is a document that is part of the safety system in environments where there is a risk of explosion. The DOPV is mandatory in all facilities where flammable or explosive substances are handled, such as chemical plants, refineries, ports or industrial factories. The main objective of DOPV is to minimize the risk of explosion and to ensure the safety of workers and the environment. The DOPV contains a precise description of the safety precautions that must be followed, including instructions for working with hazardous substances, proper handling, storage and waste management. The DOPV is based on a thorough risk assessment of the plant and contains information on possible sources of explosions, their causes and measures to prevent them. The document also includes an explosion plan that sets out procedures for evacuation, rescue and firefighting in the event of an explosion. Compliance with the DOPV is mandatory by law and subject to regular inspections. Operators must ensure that all personnel who come into contact with hazardous substances or environments are properly trained and familiar with the contents of the DOPV. The DOPV is therefore a key document for explosion protection and is a comprehensive plan of safety measures to minimise risks and provide a safe environment for workers and operations.

chemical and pharmaceutical industry
Gas regulating stations
Biogas power plants, and gas regulating stations

What is needed to draw up a DOPV?

Several important factors are necessary for the creation of a DOPV, i.e. an Explosion Protection Document. Here are a few basic elements to consider:

1. Risk assessment: all possible risks associated with an explosion in the plant must be thoroughly assessed. This includes identifying the sources of explosions as well as their causes and potential consequences.

2. List of hazardous zones: based on the risk assessment, all areas in the plant where an explosion hazard is present must be identified and marked. These areas are called hazardous zones and are divided according to the degree of risk.

3. Measures and procedures: the DOPV should contain precise measures and procedures to minimise the risk of explosion in each hazardous area. These measures may include proper storage and handling of hazardous substances, use of safety equipment and devices, regular maintenance and inspections, and the like.

4. Explosion plan: the DOPV should also include a plan of action in the event of an explosion. This plan should include procedures for evacuation from hazardous areas, rescue of injured persons, as well as procedures for extinguishing and containing the explosion.

5. Training and awareness: all workers who are in contact with hazardous substances or work in hazardous areas should be properly trained and informed about the contents of the HACCP. They should have knowledge of safe procedures, use of protective equipment and response in the event of an explosion.

DOPV is required to ensure the safety of workers and operations in environments with a high risk of explosion. Its development and compliance is required by law and is subject to regular inspections to minimize the risk of explosion and protect the environment from hazardous situations.
