SOLDERING AND BRAZING
you should use leather gloves with tight fitting cuffs
that fit over the sleeves of the jacket. Many welders
wear a full set of leathers that consists of the following:
cadmium or beryllium can be extremely hazardous.
Jacket or set of sleeves
Fumes from cadmium or beryllium compounds are
extremely toxic. In fact, several deaths have been
reported from inhaling cadmium oxide fumes.
Skin contact with cadmium and beryllium should
also be avoided. An expert in industrial hygiene should
be consulted whenever cadmium or beryllium
compounds are to be used or when repairs are to be
made on parts containing the metals.
