Criteria based on the list of chemicals

• The maximum quantity of a hazardous chemical is increased and as a result
  • The scope of the activities increases (from minor to large-scale) or 
  • There is the obligation to prepare an operating principle document or safety assessment

Change notice

Risk-based criteria

• The change could significantly affect the risk of accidents in the production plant area due to the hazards of a chemical or its location
• The change requires or may require significant technical or structural changes to the handling or storage of hazardous chemicals and/or improvements to accident prevention or to limit the consequences.

  • From large-scale to small or
  • From a plant requiring a safety assessment to a plant requiring an operating principle document or a permit

Inspection (no reporting required)

• The change carries only minor risk

Risk-based criteria

• The change has or may have an impact on the environmental land use planning of the production plant
  • The areas impacted by production plant accidents increase
  • The plant’s consultation zone must be expanded or the impacts within it become more severe

Criteria based on the list of chemicals

• As a result of new chemical(s)
  • The scope of the activities increases (from minor to large-scale) or 
  • There is the obligation to prepare an operating principle document or safety assessment

Change notice

Risk-based criteria

• The chemical poses new hazards to the production plant or the chemical is more hazardous than chemicals of the same type that have previously been handled (more flammable, toxic, reactive, more hazardous state, etc.)
• The change significantly increases or may increase the risk of accidents on the production plant site, taking into account the location of the chemical and activities in question
• The new chemical requires or may require significant technical or structural changes and/or improvements to accident prevention or to limit the consequences.

Criteria based on the list of chemicals

• As a result of new chemical(s), the LPG plant requires a permit 
• A new chemical replaces an existing one and, as a result, the scope of the activities becomes smaller 
  • From large-scale to small or
  • From a plant requiring a safety assessment to a plant requiring an operating principle document or a permit 
  • From a plant requiring an operating principle document to a plant requiring a permit

Inspection (no notice required)

• The change carries only minor risk
• The change has no impact on the areas affected by accidents at the plant 
• The new chemical has similar hazardous properties to existing chemicals
• The change does not call for technical/structural alterations or the alterations are not significant

Change permit

• As a result of a change in the hazard classification of a chemical
  • The scope of the activities increases (from minor to large-scale) or
  • There is the obligation to prepare an operating principle document or safety assessment

Change notice

• Downward change in scope due to a change in a chemical's hazard classification

Inspection (no notice required)

• Changes to the hazard classification do not cause changes to the handling or storage of the chemical
• Changes to the hazard classification that do not affect the scope of operation are processed as part of periodic inspections (processing of the chemical list)

Change permit

Risk-based criteria

• The change has or may have an impact on the environmental land use planning of the production plant
  • The areas impacted by production plant accidents increase
  • The plant’s consultation zone must be expanded or the impacts within it become more severe
  • The change involves new types of major accident risks for the production plant, and accidents may have consequences beyond the plant site

Criteria based on the list of chemicals

• As a result of changes to the process or storage conditions, the scope of operation becomes larger (from minor to large-scale) or the operator s obligated to prepare an operating principle document or safety assessment.
  • For example, this is possible in the case of flammable liquids (P5a-P5c) where the condition is taken into account when calculating the ratio

Change notice

Risk-based criteria

• The way a hazardous chemical is handled or manufactured changes significantly, and the change affects the risk of accidents
• The change significantly increases or may increase the risk of accidents on the production plant site, taking into account the location of the chemical and activities in question
• The process conditions (e.g. pressure or temperature) change in a way that significantly affects process safety
• The change requires or may require significant technical or structural changes and/or improvements to accident prevention or to limit the consequences.

Criteria based on the list of chemicals
