Whenever you are involved in a Ex compliance project of possible hazardous area industries, the goal is always the same and so the to-do-s.
Just had a meeting with the owner of an instrumentation manufacturing company, where small percentage of the total area was about aluminium grinding.
He was quite shocked what all needs to be done – he claimed about being not an oil refinery.
If Ex is there, all Ex safety relevant issues shall be considered and owner of site shall act accordingly.
Keep up good work!
