    Attention should be paid to the forging process
    1 forging process includes: the material is cut into the required size, heating, forging, heat treatment, cleaning and inspection. In the small artificial forging, all of these operations are carried out by several blacksmith overhand and underhand in narrow places. They are all exposed to the same harmful environment and occupation hazards; in large forging workshop, the harm with the jobs vary.
    Despite the different working conditions and working conditions for forging in different forms, but have some common characteristics: moderate intensity physical labor, the microclimate environment of dry heat, noise and vibration, air polluted by smog.
    2 workers are also exposed to high temperature air and heat radiation, cause heat accumulation in vivo, calories plus metabolic heat, will cause the heat imbalance and pathological changes. 8 hours of labor amount of sweat with small gas environment, energy consumption and thermal adaptability vary in general 1.5~5 liters, or even higher. In smaller or more distant from the heat forging workshop, Behar's two index of heat stress is usually 55~95; but in large forging workshop, near the furnace or drop hammer machine work could be as high as 150~190. Easy to cause the lack of salt and heat cramps. In the cold season, exposure to small changes in climate may promote its adaptability to a certain extent, but the change rapidly and frequently, may pose a health risk.
    Air pollution: may contain smoke, carbon monoxide and dioxide, sulfur dioxide as places in the air, or contain acrolein, its concentration depends on the heating furnace fuel type and impurities, and the combustion efficiency, air flow and ventilation condition.
    Noise and vibration: type hammer will produce noise and vibration, but there may also be some high frequency components, the sound pressure level between 95~115 db. Workers exposed to vibration caused by forging, temperament and functional disorders, reduces work capacity and safety.
