Our coke drum structure is exposed to high radiant heat from a nearby flare. We elected to provide heat shielding on exposed platforms facing the flare and on all egress staircases. Our team has also identified the need to shield the stairs from fires on the decks themselves. I have 2 questions:
1 - Do I need to specify a specific firewall/barrier type and rating (1 hour, 2 hour, etc...)in any of these cases (radiant heat and fire)?
2 - I have chosen not to add doors to the staircases so as not to impeded evacuation and not trap fugitive fumes. Are we required to have fire rated doors for these areas? Doesn't seem logical to me.
Thanks for any help I can get!
