Key Points Fire  Elemental nickel dust and nickel carbonyl are flammable  Nickel is incompatible with acids, oxidizing agents and sulphur  Nickel and nickel carbonyl react violently with oxidants  Nickel and nickel compounds emit toxic fumes and vapours of nickel carbonyl when heated to decomposition  In the event of a fire involving nickel carbonyl, use fine water spray and gas tight kit ...

Welding work is associated with the inhalation of fumes and accumulation of particulates in welders' lungs. It is assumed that particulates deposited in the respiratory system, mainly consisting of iron oxides, are eliminated by several mechanisms, such as muco-ciliary transport and macrophage phagocytosis. In their cross-sectional study of 42 Finnish shipyard arc welders, Kalliomäki et al. ind...

OBJECTIVES To examine the effect of chronic exposure to welding fumes on pulmonary function by a direct estimate of fumes accumulated in the lungs. METHODS The strength of the residual magnetic field of externally magnetised lungs (LMF) was used as an estimate of fumes accumulated in the lungs. The results of forced spirometry manoeuvres obtained in 143 of 153 male welders in the original sam...

in order to evaluate the relationship between the concentration of welding fumes and cigarette smoke on the bronchopulmonary system function, a comparative study of spirometric measurements in 100 welders and 50 healthy volunteers was performed in an automobile manufacturing company. two groups of workers were matched according to their age, height, smoking habit, years of service and social cl...

The type of lung disease caused by metal compounds depends on the nature of the offending agent, its physicochemical form, the dose, exposure conditions and host factors. The fumes or gaseous forms of several metals, e.g. cadmium (Cd), manganese (Mn), mercury (Hg), nickel carbonyl (Nl(CO)4, zinc chloride (ZnCl2), vanadium pentoxide (V2O5), may lead to acute chemical pneumonitis and pulmonary oe...

Poisoning from exposure to fresh cadmium fumes at work has long been described but cases may remain undiagnosed. The diagnosis of acute cadmium poisoning should be considered in any workman who has been occupied in high temperature welding in confined spaces. Surfaces electroplated with cadmium may go unrecognised and present a significant hazard. Freshly formed cadmium oxide fumes may cause pu...
