I'm thinking that it's diesel fuel also. Gasoline would surely have an adverse affect (melting) some of those plastics that they are using/wearing. Too, the fumes aren't quite as volatile as gas and it's not nearly as hard on one's skin as gas. Diesel can be used for tractors, pumps and heating which I am sure, these poor souls deal with on a daily basis.
Now excuse me. I'm off to buy some BP stock.
