Section 4 - Safety Information: General Safety
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
exist 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 restricted 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 being 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 concentrations 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 ventilation.
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.
In industrial and contractor applications, it is advisable to
run frequent tests to determine the exact concentration of
isocyanate vapor in the air. Industrial equipment is available
for making such determinations. Your chemical supplier can
recommend such equipment and procedures.
Proper Safety Equipment
All persons spraying or working is areas where forced air
ventilation is not adequate to remove isocyanate vapors
from the air MUST use an approved (U.S. Bureau of Mines)
fresh air supplied respirator.
Respirators should be regularly inspected, cleaned and dis-
infected according to good practices. Records must be kept
of the inspections. The user MUST have a medical clear-
ance indicating that he can safely use a respirator.
Respirators must fit securely; beards prevent a tight seal
around the face. Eye glasses have to be given special atten-
tion and contact lenses are prohibited.
Safety goggles, gloves and other protective devices are sug-
gested for operators of foaming equipment. Refer to OSHA
Standards, sub-part 1, 1910.132, 1910.133 and 1910.134
for Federal standards.
