11. Polyurethane
Reactive
("PUR")
Hot Melt Material
(contd.)
Because isocyanate ingredients are found
in various concentrations in
reactive materials
produced
by ditferent manufacturers, it is imperative
that the material
manufacturer's MSDS or material information sheet
be
consulted BEFORE using reactive material.
Pay
particular
attention
to the
discussion of materialtoxicity,
health
effects,
and reactivity condition.
There are certain universal safety
guidelines
that should be followed
when using any reactive material:
O
a
Recommended
processing
temperatures must
not be exceeded.
When handling and
using reactive material, always wear thermally
protective gloves
and long-sleeved clothing.
Wear chemical
goggles
to reduce the
potential
of eye contact.
Have eye washes available and
provide
a cold water source
for burn
treatment.
The regular use of barrier cream for hands and face is recommended
for
skin
protection.
Do
not
eat, drink, smoke, or store food in working areas where
PUR
material
is being
processed.
Wash hands thoroughly after
working with reactive material.
Remove hot melt materialvapors using suitable
extraction ventilation
equipment.
Use appropriate respiratory equipment
where
there
is
the danger
of
inhaling isocyanate
vapors
or other
ingredients contained in the PUR
material in concentrations exceeding
permissible
limit values.
ln case of
very high
concentrations
of harmful substances, or if
you
are unsure of the environmental conditions,
respiratory
protective
equipment
(operating
independent of the surrounding
air) must be
used.
Do not operate the unit with PUR materials if
you
are unsure that
ALL
adequate safety measures have been taken.
