EPD must contain the following

The Explosion Protection Document (EPD) is the basic safety document which is crucial for all operations where substances capable of forming an explosive mixture with air are present.

Government Regulation GR 406/2004 Coll., exactly stipulates the requirements on contents of the Explosion Protection Document for it to be valid. The EPD prepared by us always comprises all mandatory items. In addition to that, it contains other information which we believe must be included in the documentation so that it can be used in practice and not just to satisfy the legal requirements. Once we start working on such document, why not to use it also as the groundwork for employees training, equipment repairs and inspections, etc.?

EPD content:

  • information about the particular operation, assessment scope
  • technological procedure, description of the equipment and work operations
  • legislation, standards, and literature used
  • terms and definitions
  • fire-technical characteristics of substances
  • impact of technological procedure on fire-technical characteristics of substances
  • determination of relevant initiation sources
  • identification of premises and equipment with possible occurrence of substances forming explosive mixture with air
  • determination of primary and secondary leaks of explosive dusts and places with permanent presence of dust layers or deposits
  • determination of permanent, primary, and secondary leaks of flammable liquid vapours and explosive gases
  • determination of the degree and reliability of ventilation in individual premises with the occurrence of explosive gases and flammable liquid vapours
  • assessment of the possibility of explosive dust settlement and formation of sediments
  • calculation of hypothetic volumes of explosive atmospheres or normative specification of volumes
  • determination of zones in areas outside the technology
  • determination of (expected) time of explosive atmosphere presence inside the technology
  • assessment of possible initiation sources both outside and inside the technology and their ability to initiate the present explosive atmosphere
  • determination of risky premises and equipment
  • analysis of risks and consequences of a potential explosion
  • design of preventive and technical measures against explosion
  • specification of equipment-related requirements (both electrical and mechanical) intended for use in premises with explosion hazard
  • requirements on marking the premises with warning signs
  • requirements on execution of activities with increased hazard (for example grinding, welding, etc.)
  • Form V Order
  • Annexes
