Safe use of nickel in the workplace Module 1: toxicology and hazard classifi cation of nickel substances
SUMMARY - Nickel is a naturally occurring element that exists in nature
mainly in the form of sulfide, oxide, and silicate minerals.
Because it is ubiquitous, humans are routinely exposed to
nickel in various amounts. “Zero exposure” to nickel is thus
not possible. Nickel has been shown to be an essential
element in certain microorganisms, animals, and plants. The
generally held view is that nickel is probably an essential
element for humans as well.
Nickel is an extremely important commercial element. Factors
which make nickel and its alloys valuable commodities
include strength, corrosion resistance, high ductility, good
thermal and electric conductivity, magnetic characteristics,
and catalytic properties. Its principle use is in stainless steels
which are particularly valued for their hygienic properties.
In some applications, nickel alloys are essential and cannot
be substituted with other materials. Nickel plays important
roles in environmental technologies to mitigate climate
change, and alternative sources of energy. In recent years, the
applications of nickel in the energy field, such as in electric
batteries and energy storage, have increased. Given its many
beneficial properties, nickel is used in a wide variety of
products discussed below.CONTINUE READING ON: nickelinstitute.org
