Hi Guys.
I have been working in an Ammonia Plant Room for the last couple of days which has had a block wall built across the Plant Room Double doors and the Fire Escape Door.
Am I right to be concerned about this?
See Attached!

They don't look that big, but when you approach them you have to remember to take a big step over them.
Coming out of the plant room potentially in a Escape Hood or Respirator, You could really hurt yourself!
Also A large sign has appeared on the fire door which says within a Yellow Triangle 2NE Explosive Atmosphere.
Can someone enlighten?
