§ 3 Definitions

Definitions as mentioned in Section 6 of the Framework Regulations apply correspondingly for these regulations.
The following definitions apply for these regulations:

Land-use plan:
Overview showing planned placement location of equipment and installations, access routes, internal traffic patterns and enclosures.

Area restriction:
A certain delineated area with specified use restrictions surrounding equipment and installations.

Fire area:
Area, building or room that is separated from other areas by a fire division, such that the likelihood of spread in the event of a design fire load is reduced.

Fire division:
Distance or division made of incombustible materials.

Design load:
Characteristic load multiplied by load coefficients.

Hazardous substance:

Flammable substance: Solid, liquid or gaseous substances, mixture of substances, as well as substances that occur in combinations of such states, which due to their flash point, contact with other substances, pressure, temperature or other chemical properties, represent a fire risk.

Explosive substance: Other solid, liquid or gaseous substances, mixture of substances, as well as substances that occur in combinations of such states, which due to their properties can easily cause an explosion through impact, friction, or through contact with ignition sources or other substances.

Reactive substance: Solid, liquid or gaseous substances, mixture of substances, as well as substances that occur in combinations of such states, which upon contact with water, at their pressure, temperature or other chemical properties, represent a risk of dangerous reaction, explosion or emission of dangerous gas, vapour, dust or mist.

Pressurised substance: Solid, liquid or gaseous substances or mixture of substances other than fire or reactive substances, which are under pressure, and which can thereby represent a danger in the event of uncontrolled emission.

Main area:
Area or building block on the facility that contains identical or similar functions.

Process facility:
A physical system consisting of equipment that alters the properties of the process media.

Safety functions:
Technical barrier elements that are intended to reduce the possibility of a concrete fault, hazard and accident situation occurring, or that limit or prevent damage or inconveniences.

Safety system:
Technical barrier elements that are realised in a common system.
