I've gloved 7200 off the pole quite a lot. It was allowed in the safety rules, both for the contractor I was working for, as well as the utility whose property we were working on. It isn't an OSHA thing, it varies by utility and by state. Same for gloving out of a bucket, 34.5kv is allowed in many parts of the country, some areas you can't glove over 4kv.
