Short answer: Explosive atmosphere risk assessment is the study that systematically identifies the risks of explosions caused by flammable gases, vapors, or dusts in a facility, and forms the basis of the Explosion Protection Document (EPD).
Every business operating in an explosive environment is obligated to protect its employees and facilities from the risk of explosion. The first step is to scientifically determine where, how frequently, and with what intensity the risk may occur.
Measures taken without risk assessment are either insufficient, leading to fatal accidents, or excessive, resulting in significant costs. A proper risk assessment ensures that protection is both safe and economical.
What is involved in risk assessment?
- Inventory of flammable materials and identification of leakage sources.
- Zone classification
- Identification and evaluation of ignition sources.
- Analysis of existing and necessary protective measures.
- Data generation for Explosion Protection Document (EPD).
Relationship with Explosion Protection Document (EPD)
The Regulation on Protection from the Hazards of Explosive Atmospheres mandates the preparation of an Explosion Protection Document (EPD) for workplaces containing explosive atmospheres. Risk assessment is the core of this document: it identifies which areas belong to which zones, what ignition sources may be present in those areas, and what protective measures have been taken. The validity and up-to-dateness of the EPD depend on the accurate conduct of the risk assessment and its updating as processes/equipment change. Therefore, risk assessment is not a one-time event, but a living process.
Legal Framework and Assessment
Explosive atmosphere risk assessment and explosive content assessment (ECA) are mandatory under the relevant regulations; the study must be carried out and documented by experts in the field.
