Hand shields or helmets provide eye
protection by using an assembly of components such as a helmet shell. This
helmet must be opaque to light and resistant to impact, heat and electricity. Outer
cover plate made of polycarbonate plastic which protects from UV radiation,
impact and scratches. This helmet also includes filter lens made of glass
containing a filler which reduces the amount of light passing through to the
eyes.
Filters are available in different shade numbers ranging from 2 to 14.
The higher the number, the darker the filter and the less light passes through
the lens. Clear retainer lens made of plastic prevents any broken pieces of the
filter lens from reaching the eye. Gasket made of heat insulating material
between the cover lens and the filter lens protects the lens from sudden heat
changes which could cause it to break. In some models the heat insulation is
provided by the frame mount instead of a separate gasket.
This sign was created to last in the
toughest industrial environments. These signs are available in the classic OSHA
format as well as in the ANSI spec. You can choose from any format. These signs become encapsulated under high
temperature and pressure inside 50 mils of rigid PVC. They are also resistant to chemicals,
weather, physical abuse and tampering. Many of these signs are enhanced with
OSHA/ANSI symbols. They can be delivered with either brass eyelets or adhesive
mounted. Potential buyers can inquire for prices of semi custom signs and for
signs over a quantity of 50.
