Carbon monoxide CO is the main occupational disease hazard factor in metallurgical iron and steel enterprises, with many workplaces, wide distribution range, and wide contact with the crowd. The content of carbon monoxide in the gas is about 30%, and carbon monoxide poisoning may occur in the posts exposed to the gas if no attention is paid to the protection.
Harmful gas introduction in metallurgical :
50ppm Permissible exposure concentration for 8 hours of exposure (OSHA).
200ppm 2-3h may cause a mild forehead headache.
400ppm 1-2h Forehead headache with vomiting , 2.2-3.5h vertigo.
800ppm 45min Headache, dizziness, and vomiting, 2h coma and possible death.
1600ppm 20min Headache, dizziness, and vomiting, 1h coma and possible death.
3200ppm 5-10min Headache, dizziness, and vomiting, 30min coma and possible death.
6400ppm 1-2min Headache, dizziness, and vomiting, 1-15min coma and possible death.
12800ppm Immediate unconsciousness. 1-3 min danger of death.
MIC-500S-CO-A , MIC-500S-O2-A
