7. Disassembly
The following points are particularly important for the disassembly of systems which pose an
explosion hazard.

Applicable regulations for the disassembly of electrical systems must be followed.

Check that no gas is present before and during the work.

Seal any openings gas-tight which could otherwise allow the spread of an explosive
atmosphere.

Do not use electrical equipment capable of generating sparks (saw, cutting grinder...) for
disassembly. If this is unavoidable, ensure compliance with EN 1127.

Use low-sparking tools.

Avoid any build-up of electrostatic charge (e.g. due to friction).

Contaminated components (potential outgassing) should be disposed of appropriately.
