Intrinsic Safety and its properties
The important principles for integrated safety explosion protection are as follows:
- Measures are taken to avoid hazardous atmospheres whenever possible.
- Measures are taken which prevent the ignition of hazardous atmospheres.
- Measures are taken which limit the explosive effect to a safe degree.
This differs from:
Primary explosive protection
These are precautions taken to prevent or restrict the formation of hazardous explosive atmospheres.
Secondary explosive protection
This covers the second group of measures, which are intended to prevent the ignition of an atmosphere that is capable of exploding.
Tertiary explosive protection
Measures to limit the effects of an explosion (e.g. by pressure relief valves).
Zones - Areas of responsibility for the company
At all places where flammable substances are produced, processed, transported or stored, safety is extremely important - especially in the chemical industry, petrochemical industry, in oil and natural gas production and in mining.

Fundamentals of dust explosion protection
The manufacturer of equipment intended for use within areas that contain potentially explosive concentrations of dust and air must indicate the maximum surface temperature of the equipment in °C (prefixed with the letter ‘T’). This temperature is part of the dust Ex-designation.

Category 3 devices
In contrast to Category 1 and 2 devices, potential hazards in the event of failure (e.g. short circuiting, connection break etc.) do not have to be considered for Category 3 devices (for use only in Zones 2 respectively 22).
