Polyurethane Reactive
("PUR")
Hot Melt Material
(contd)
Because isocyanate ingredients
are
found in various
concentrations
in
reactive
materials
produced
by
different
manufacturers, it is imperative
that the material manufacture/s MSDS or material information
sheet be
consulted BEFORE using reactive material. Pay
particular
attention to the
discussion of material
toxicity,
health effects, and reactivity condition.
There
are certain universal safety
guidelines
that should be
followed
when using any reactive material:
a
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.
