We have an exit enclosure that is rated as Class I Division I. My understanding of an accessible route and means of egress, is that it is a "safe" means of egress.
Can an accessible route have a Class I Division I (explosion hazardous classification), or does it need to be purged and pressurized according to Type X requirements? Submitted anonymously and posted for discussion. Discuss This | Submit Your Question | Subscribe

I believe if the egress area is a Group H area then no you cannot use it as an egress.

I’m agree. To further reiterate, I think NFPA 101 classified this as a high-challenge fire scenario, a flammable gas in the means of egress, therefore requiring a high challenge fire wall in accordance with NFPA 221 per NFPA 101 Section 8.3.1.3.

I guess the question is "Is it required to have an exit enclosure as Class I Div 1?" No. There is also not a requirement to pressurize the enclosure under normal circumstances. Leave a Reply. |
