I've watched a lot of these 3rd world repair jobs. No safety glasses, maybe hold up a tinted lens with one hand weld with the other, no shoes or boots just sandals while cutting, welding, grinding and jacking. No jack stands either, They repair everything, weld cranks and camshafts back together then true them on a lathe, still not wearing glasses. Rebuild a wrecked heavy duty truck on the side of the road. Straighten u-bolts, rebuild spring packs, beat a wheel straight, it's amazing. there is no word in their language for OSHA.
