HEALTH HAZARD INFORMATION
______________________________________________________________________
EFFECTS OF OVEREXPOSURE:
INHALATION: Vapor or mist can irritate the nose and throat.
Extended exposure will lend to headache, nausea,
drowsiness and unconsciousness.
SKIN CONTACT: Slightly irritating to skin.
EYE CONTACT: Moderately irritating to eyes.
DELAYED EFFECTS Substance can cause allergic reaction on skin.
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Move subject to fresh air. Give artificial respiration
if breathing has stopped. SEE A PHYSICIAN.
EYE AND SKIN CONTACT:
Flush eyes with a large amount of water for at least 15 minutes.
See a physician if irritation persists. Wash affected skin areas
with soap and water.
INGESTION: If swallowed, dilute by giving 2 glasses of water to
drink. SEE A PHYSICIAN.

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), impervious clothing and boots. 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 may 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. Product is slightly toxic to fish.
NOTE: Spills on porous surfaces can contaminate ground water.
WASTE DISPOSAL METHODS:
3
When discarded this material is a hazardous waste. RCRA #D-001
ignitable; reportable quantity 100 lbs. (40 CFR Part 302)
"Superfund". Incinerate liquid and the contaminated diking
material, in accordance with local,state,and Federal regulations.

SPECIAL PROTECTION INFORMATION
______________________________________________________________________
VENTILATION TYPE: Mechanical local exhaust ventilation at point of
contaminant release.
RESPIRATORY PROTECTION:
One required if good ventilation is maintained. Otherwise wear
self-contained breathing apparatus (pressure-demand, MSHA/NIOSH
approved or equivalent).
PROTECTIVE GLOVES: Impervious
EYE PROTECTION: Chemical splash goggles (ANSI Z-87.1 or approved
equivalent)
OTHER PROTECTIVE EQUIPMENT:
Eyewash facility, safety shower, impervious clothing.

STORAGE AND HANDLING INFORMATION
______________________________________________________________________
STORAGE TEMPERATURE: Max. AMBIENT Min. (1)
Store out of direct sunlight at ambient temperatures. Leave air
space over liquid surface in all containers. Ground all
containers when transferring material. Use within one year of
date stamped on label. Monitor inhibitor level during storage
using CM-18.
Material stored in bulk should be tested for stability every month;
drums and bails every 3 months.

TOXICITY INFORMATION
______________________________________________________________________
Acute oral LD50, rat: 20,300 mg/kg;
Acute dermal LD50, rabbit: 10,200 mg/kg;
Acute inhalation LC50, rat: >2,900 ppm for 8 hours.

MISCELLANEOUS INFORMATION
______________________________________________________________________
Monomer stability is a logarythmic function of time vs. temperature.
Stability is also dependent on inhibitor concentration, the presence
of air and type of monomer.
NOTE: Use local exhaust ventilation with a minimum capture velocity of
100 ft/min. (30 m/min.) at the point of monomer evolution.
