What is PKD?

It is a document that must be prepared in all companies with flammable, flammable and explosive chemicals and must be shown to inspectors during the inspections of the Ministry Labor Inspection Board with the “Regulation on the Protection of Employees from the Dangers of Explosive Atmospheres” law.

Why is an Explosion Protection Document Necessary?


In case of any emergency, if the personnel in the enterprise does not know how to act, life and property loss may occur. In order to prevent such events such as loss of life and property, these enterprises should prepare an Explosion Protection Document and take the necessary measures in the light of this document. The Explosion Protection Document is the documents stating what is required to prevent the personnel in the business from being damaged, to minimize the risk of any explosion occurring in the construction machinery and to prevent the damages that may occur in dangerous situations as much as possible.


In environments containing flammable explosive substances, it is the employer’s obligation to define a dangerous zone and to prepare an explosion protection document.


  • In the scope of the Occupational Health and Safety Law No. 6331 dated 20.06.2012, companies that do not have an Explosion Protection Document can suspend the activity and impose administrative fines up to 89.629 TL.



Where to Prepare PKD?

It is prepared for businesses with or likely to have Flammable – Flammable Gas / Liquid / Dust.

  • LPG and other petroleum products production, filling and distribution facilities
  • Flour mills
  • Transformer workshops
  • Pressurized flammable gas cylinder tanks
  • Electrical device and equipment manufactories
  • Oven or electrostatic paint workplaces
  • Raw leather workshops
  • Some parts of battery workshops
  • Olive oil and other oil mills
  • Paint and thinner workshops
  • Chemical analysis laboratories
  • Printing Houses
  • Pharmaceutical manufacturing industry
  • Chemical warehouses
  • Battery charging areas of facilities
  • Fuel storage tanks



Why and How Often Should the Explosion Protection Document (PKD) be Revised?

Changes in chemicals, processes or equipment can cause dangerous areas to change. This change may require the explosion protection document to be reviewed and revised.

For example;


New source of discharge that occurs after a change in process,

  • The chemical falls into the flammable category as a result of chemical change or process change,
  • Change in process pressure,

New sources of discharge that arise with the changes in the operation steps,

  • Change in ventilation conditions used in the dangerous area,

Changes of equipment and instruments used in the hazardous area within the scope of process improvement or revision

When it occurs, the Explosion Protection Document should be revised and finalized. In addition, the Explosion Protection Document (PKD) should be reviewed and revised after the changes in the standards. When the good practice examples of international organizations are examined, it is seen that review and revision studies are carried out every five years without any change.
