METAL FUME FEVER

When galvanized metal is being welded, the fumes may contain zinc oxide from themetallic coating and unless its inhalation is prevented, a feeling of chill with shiveringand perspiring may follow.

This is known as MET! "#ME "E$E%. The effects are usually acute and transitory,coming on a few hours after the fumes have been inhaled and passing off completely in&' hours.

(iven proper planning, there is no reason why these cases should occur at all.)rovision should always be made for the removal of fumes by mechanical means. Thisis best achieved by using localized exhaust ventilation where an elongated hood isplaced near to the seam being welded.

nother practical method is to use an air mover.

*ne of these two methods should always be used when work is taking place inside. *noutside work, some dilution of the fume is already taking place but reliance on the windfactor is not always sufficient.

%espiratory protection need only be worn when mechanical ventilation cannot be used.
