Actually a loose-fitting hood can be quite acceptable in some circumstances and may well BE under positive pressure. This is especially true for a supplied-air system, where you are not carrying a limited air supply in a cylinder on your back.

I don't believe you can wear a loose fitting hood. I understand you need a positive pressure respirator. No leakage. Also, the "Buddy System" kicks in. The Buddy also has to be equipped and trained to execute a rescue, if needed. Whenever there is a potential for an IDLH atmosphere, or if the hazard is unknown, 29CFR1910.134 applies, to my understanding.
