SPECIAL FIRE FIGHTING PROCEDURES:
Do not enter fire area without proper protection. Fight fire
from safe distance/protected location. Heat/impurities may
increase temperature/build pressure/rupture closed containers,
spreading fire, increasing risk of burns/injuries. Water may be
ineffective in firefighting due to low solubility. Use water
spray/fog for cooling. Pressure relief system may plug with
solids, increasing risk of overpressure. Notify authorities if
liquid enters sewer/public waters.
UNUSUAL FIRE AND EXPLOSION HAZARDS:
Heat can cause polymerization. Heated containers can explode.
Vapors can travel to a source of ignition and flash back.

EMERGENCY AND FIRST AID PROCEDURES:
ROUTES OF ENTRY:
INHALATION: Move subject to fresh air. Give oxygen.
EYE/SKIN:
Flush eyes with large amounts of water for at least 15 minutes.
Consult physician if irritation persists. Wash affected skin
area with soap & water. Vapor or mist can irritate the nose or
throat. Can cause severe irritation or possible permanent
injury. Irritating to skin upon repeated or prolonged contact.
Material is possible harmful if swallowed.

STORAGE AND HANDLING INFORMATION
______________________________________________________________________
STORAGE TEMPERATURE: 32oC/90oF - Maximum
Store out of direct sunlight in a cool place. Do not store near
radiators, steampipes, and other sources of heat. Do not store under
oxygen-free atmosphere. Leave air space over liquid surface in all
containers; introduce air periodically if stored more than 6 months.
Use material within 1 year of retest for stability. Stability-test
material stored in bulk every month; drums and pails every 3 months.
Use positive pressure to replace air in vapor spaces of containers
after sampling.

SPILL OR LEAK PROCEDURE INFORMATION
______________________________________________________________________
STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED:
Keep spectators away. Eliminate ignition sources. Use
self-contained breathing apparatus (pressure-demand, MSHA/NIOSH
approved or equivalent) for large spills in confined area. Dike
and contain spill with inert material (e.g. sand, earth).
Transfer liquid to containers for recovery or disposal and solid
diking material to separate containers for disposal. Contaminated
monomer can be unstable. Add extra inhibitor to prevent
polymerization. Remove contaminated clothing promptly and wash
affected skin areas with soap and water. Keep spills and
cleaning runoffs out of municipal sewers and open bodies of water.
NOTE: Spills on porous surfaces can contaminate groundwater.
WASTE DISPOSAL METHODS:
Incinerate liquid in approved equipment. Landfill or incinerate
contaminated diking material in accordance with local, State and
Federal regulations.

PERSONAL PROTECTION MEASURES
______________________________________________________________________
RESPIRATORY PROTECTION:
A respiratory protection program meeting OSHA 1910.134 and
ANSIZ88.2 requirements must be followed whenever workplace
conditions warrant a respirator's use. None required if airborne
concentrations are maintained below the TWA/TLV's listed on the
Component Exposure Information section.
Up to 10 times the TWA/TLV: Wear a MSHA/NIOSH approved (or
equivalent) half-mask, air-purifying respirator.
Up to 100 times the TWA/TLV: Wear a MSHA/NIOSH approved (or
equivalent) full-facepiece, air-purifying respirator.
Above 100 times the TWA/TLV or unknown: Wear a MSHA/NIOSH
approved (or equivalent) self-contained breathing apparatus in
the positive pressure mode, or MSHA/NIOSH approved (or
equivalent) full-facepiece airline respirator in the positive
pressure mode with emergency escape provisions.
Air-purifying respirators should be equipped with organic vapor
cartridges.
EYE PROTECTION:
Use chemical splash goggles and face shield (ANSI Z87.1 or
approved equivalent). Eye protection worn must be compatible
4
with respiratory protection system employed.
HAND PROTECTION:
The glove(s) listed below may provide protection against
permeation. Gloves of other chemically resistant materials may
not provide adequate protection: Nitrile, Neoprene.
Rinse and remove gloves immediately after use. Wash hands with
soap and water. Gloves should be removed and replaced
immediately if there is any indication of degradation or chemical
breakthrough.
NOTE: Material is a potential skin sensitizer.
OTHER PROTECTION:
Use chemically resistant apron or other impervious clothing to
avoid prolonged or repeated skin contact.
VENTILATION:
Use local exhaust ventilation with a minimum capture velocity of
100 ft/min. (30 m/min.) at the point of vapor evolution. Refer
to the current edition of INDUSTRIAL VENTILATION: A Manual of
Recommended Practice published by the American Conference of
Governmental Industrial Hygienists for information on the design,
installation, use and maintenance of exhaust systems.
