Cement plant employees protected from dust and dirt
January 1st 2009 At the Holcim (Deutschland)
AG Lägerdorf site in
Germany, employees working
in cement production now wear
limited-use type 5/6 chemical
protective garments made of DuPont
Tyvek Classic to protect them from
dust and dirt.
To keep flames in the kiln
continually burning at temperatures
to 2000°C, necessary to enhance the
quality of the compound and the
end product, the fuels are fed into
the rotary kilns as finely dispersed
powders, flakes and/or fluff. These
substances are prone to creating dust.
Chemical protective garments are
required to protect employees who,
on a daily basis, inspect a large
number of secondary or substitute
fuel metering and conveyor systems
or carry out routine maintenance.
Tyvek material has a high liquid
and particle barrier, low specific
weight and high resistance to tear,
tear growth and abrasion, while
ensuring an effective level of
permeability to air and water vapour.
At Holcim, the garments have proved
a reliable barrier against air-borne
particles, even those with a diameter
of just 1µm and have now been
selected for the company's second
plant near Hanover. More articles from Dupont Personal Protection: |
