Considering a Survey Job - Respiratory Concerns

Hi,

I’m thinking about a potential job as a surveyor at an open pit coal mine in the Rockies. I love the area, the people at the mine seemed really friendly at the site visit, and the pay/schedule/benefits are hard to beat elsewhere. The massive fear I have is the damage to my lungs. I’m an avid trail runner and backcountry skiier. I plan to get and maintain a PAPR and wear it 24/7 365 days a year whenever I’m there, and only take it off when I enter the site office. Will that be enough though? I’m planning on keeping the job for 10 years maximum.

Are there any outdoor roles here like surveyors that can speak to this? Especially ones that are runners?
