If an atmosphere subject to explosion cannot be prevented in a work area, secondary explosion protection is brought to bear. Secondary measures include prevention of any ignition sources in the Ex area.
However, these are not so easy to detect. Only with knowledge of what can cause a spark or heat can measures be taken to prevent explosions. The ignition sources are listed in the basic standard EN 1127-1 “Atmosphere subject to explosion – Explosion protection Part 1” as well as in the “Technical rules for operational safety” TRBS 2152, Part 3. Appropriate protective measures for preventing ignition sources are also listed there.
