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.
