I was looking up information for a friend of mine in regards to blacksmithing (currently we are making a RR spike tomahawk). And I was wondering what are the dangers of blacksmithing? I have read that eye protection would be needed because of infrared radiation, (what kind of eye protection would be needed)? carbon monoxide poisoning (this one is obvious if blacksmithing indoors and not enough ventilation is provided), and I have also read where using poor coal could damage your lungs. (I have also read wood charcoal is the best to use in regards to no sulfer content). Going further in research it also seems that alloys of steel and steel itself along with wrought iron have coatings on them that contribute to metal fume fever. Wrought iron has lead painted on it which is not good in itself. So, how would you protect your lungs? What kind of respirator would one use? Also, what kind of metal? So, my question is, what are the dangers of blacksmithing and how do you protect yourself from these dangers?
