Does wearing a hard hat/safety helmet for long periods at work affect the transplanted hair?

Hi. I'm considering getting a HT surgery but I'm having a concern; I work offshore on oil rigs and I often spend 30 days with my hard hat on for 6 - 8 hours a day, with also super sweaty head an scalp. Is it safe to get 1 or 2 months off for the surgery then get back to this routine? Also, I'm planning to leave this job in a year, would you recommend I wait till I leave this job completely then do the HT? or is it 100% safe if I just wait 1-2 months recovery then back to work?
