Glas Craft MH II User Manual page 40

If a person accidentally swallows isocyanate, large
amounts of water should be swallowed immediately.
Vomiting should then be induced by patient sticking his
finger down his throat, or by swallowing large quantities
of warm salt water or warm soapy water. After vomiting,
more water should be taken to dilute isocyanate further.
CONTACT PHYSICIAN IMMEDIATELY.
Ventilation
WARNING
Hazardous concentrations of some chemical vapors ex-
ist before they can be smelled. Chemical component
suppliers should be contacted to determine at what
concentrations the vapors of the chemicals they supply
become dangerous, and the procedures and equipment
needed to detect such dangerous concentrations. Such
equipment should be obtained.
Adequate ventilation must be provided in any area where
foam chemicals are sprayed or poured, and wherever
the material containers are opened.
In industrial applications, foaming operations should be
restricted to specific areas, and proper ventilation should
be provided in these areas to prevent chemical vapors
from spreading. Spray foaming operations MUST be re-
stricted to a spray booth where a minimum exhaust of
100 feet per minute at the face of the booth is provided.
Special care should be taken to prevent unsuspecting
personnel both inside and outside of the plant from be-
ing exposed to chemical vapors. The chemical vapors
should be exhausted to atmosphere in such a manner
and at a sufficiently low concentration that personnel
outside the plant are not exposed to dangerous concen-
trations of chemical vapors. Refer to OSHA Standards,
sub-part G, 1910.107 and particularly sub-section (m)
for Federal standards. State and local authorities may
have applicable statutes or regulations concerning ven-
tilation.
In contractor applications (for example, at a construction
site, inside building or other enclosed space), the forced
ventilation normally provided is likely to be inadequate.
These applications, therefore, usually REQUIRE the use
of forced, fresh air respirators for all persons in the areas
where foaming operations are conducted or where the
chemical vapors are likely to spread.
Safety
In industrial and contractor applications, it is advisable
to run frequent tests to determine the exact concentra-
tion of isocyanate vapor in the air. Industrial equipment
is available for making such determinations. Your chemi-
cal supplier can recommend such equipment and pro-
cedures.
Proper Safety Equipment
All persons spraying or working is areas where forced
air ventilation is not adequate to remove isocyanate va-
pors from the air MUST use an approved (U.S. Bureau
of Mines) fresh air supplied respirator.
Respirators should be regularly inspected, cleaned and
disinfected according to good practices. Records must
be kept of the inspections. The user MUST have a medi-
cal clearance indicating that he can safely use a respira-
tor.
Respirators must fit securely; beards prevent a tight seal
around the face. Eye glasses have to be given special
attention and contact lenses are prohibited.
Safety goggles, gloves and other protective devices are
suggested for operators of foaming equipment. Refer to
OSHA Standards, sub-part 1, 1910.132, 1910.133 and
1910.134 for Federal standards.
