Eye:
Can cause slight irritation and skin sensitisation
Skin:
Inhalation of vapour or mist can cause irritation of nose and throat.
Inhaled:
Repeated or prolonged exposure can cause headache, nausea, drowsiness,
Chronic:
unconsciousness, allergic skin reaction. Near lethal concentations can cause
kidney and liver damage.

Swallowed:
unconscious person. See a physician.
Immediately flush eyes with copious amounts of water for at least 15 minutes.
Eye:
Consult a physician if irritation persists.
Remove and wash contaminated clothing thoroughly. Wash skin with soap and

PRECAUTIONS FOR USE
Butyl methacrylate: TWA 50ppm STEL 75ppm
Exposure Standards:
Isobutyl methacrylate: TWA 50ppm STEL 75ppm
Use local exhaust ventilation with a minimum capture velocity of 30m/min at
Engineering Controls:
the point of vapour evolution.
A respiratory protection program meeting OSHA 1910.134 and ANSI 288.2
Personal Protection:
requirements must be followed whenever workplace conditions warrant use of
a respirator. None required if airborne concentrations are maintained below the
TWA/TVLs listed above.
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 with emergency escape provisions. Air- purifying
respirators should be equipped with organic vapour cartridges.
Ground all containers when transferring material. An uncontrolled
Flammability:
polymerisation may produce a rapid release of energy with the potential for an
explosion of unvented closed containers.

SAFE HANDLING INFORMATION
Store out of direct sunlight in a cool place. Avoid temperature extremes during
Storage and Transport:
storage. Ambient temperature preferred. Material can burn. Limit indoor
storage to approved areas equipped with automatic sprinklers. Total absence of
oxygen will activate the inhibitor Do not store under oxygen-free environment.
Leave air space over liquid surfaces in all containers, introducing air
periodically if stored more than 6 months. Use monomer within 1 year. DG
class 3. UN2227. Ground all containers when transferring material.
Appropriate protective equipment must be worn when handling a spill of this
Spills and Disposal:
material. Keep spectators away. Eliminate all ignition sources. Contain spills
immediately with inert materials (e.g. sand, earth). Transfer liquids and solid
diking material to separate suitable containers for recovery or disposal.
Contaminated monomer may be unstable. Add inhibitor to prevent
polymerisation. Spills on porous surfaces can contaminate ground water. Keep
spills and cleaning runoff out of municipal sewers and open bodies of water.
After the addition of excess inhibitor, incinerate liquid and contaminated diking
material in accordance with local, state and federal regulations.
Vapours can travel to a source of ignition and flash back. Heat can cause
Fire/Explosion Hazard:
polymerisation. Heated containers can explode. Use the following
extinguishing media when fighting fires involving this material: polar solvent
(alcohol) foam, carbon dioxide, dry chemical, water spray. Wear self-contained
breathing apparatus (pressure-demand MSHA/NIOSH approved or equivalent)
and full protective gear. Use water spray to cool containers exposed to fire.
OTHER INFORMATION
Avoid contact with acids, bases, oxidising agents, reducing agents, UV light.
