When safety bits become a problem, they are a problem - aka if it looks bad, it is bad (usually applied to weather decisions). Make it an ongoing subject at safety meetings, bring it up to your company, deal with it. I am.
When it gets hot my ideas are:
Helmets? Oversized white suspension system SPH4 with cooling gel inserts - does work! Carry extra gels in a small cooler bag with plastic ice inserts.
Nomex? Buy your own flight suits of a different material. I won't go in to the myriad of possible objections and etc.
High top leather boots? Who's kidding whom, and who is going to know under those overlength trousers there resides a good pair of shoes. And who will care!?
Gloves? Last I wore them was in RVN.
