Explosion Protection

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.
