2. Secure against re-commissioning.
3. Depressurize the plant or plant
component.
4. Completely drain the plant (or plant
component) and let it cool down until
the temperature is below the media
vaporization temperature and scalding
can be ruled out.
5. Correctly decontaminate, rinse and
ventilate the plant or plant component.
6. Check fl ange faces for potential damage!
7. Remove any rough areas (rust, dirt, etc.)
from the pipe fl anges.
