**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Flammable. May form explosive peroxides. Harmful by inhalation and
if swallowed. Irritating to eyes, respiratory system and skin. Toxic
to aquatic organisms, may cause long-term adverse effects in the
aquatic environment.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. A single prolonged skin exposure is not
likely to result in the material being absorbed in harmful amounts.
Ingestion:
Harmful if swallowed. May cause digestive tract disturbances. May
cause central nervous system depression.
Inhalation:
Causes respiratory tract irritation. May cause headache.
Overexposure produces central nervous system depression.
Chronic:
Not available.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, flush skin with plenty of water. Remove
contaminated clothing and shoes. Get medical aid if irritation
develops and persists. Wash clothing before reuse.
Ingestion:
If swallowed, do not induce vomiting unless directed to do so by
medical personnel. Never give anything by mouth to an unconscious
person. Get medical aid.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
**** SECTION 5 - FIRE FIGHTING MEASURES ****
General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors may form an explosive mixture with air. Use
water spray to keep fire-exposed containers cool. Containers may
explode in the heat of a fire. Liquid will float and may reignite on
the surface of water. Flammable liquid and vapor. May polymerize
explosively when involved in a fire. Vapors are heavier than air and
may travel to a source of ignition and flash back. Vapors can spread
along the ground and collect in low or confined areas. May accumulate
static electricity.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. For large fires, use water spray, fog, or
alcohol-resistant foam. Water may be ineffective.
**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****
General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Keep
container tightly closed. Keep away from heat, sparks and flame. Use
and store under nitrogen. Do not pressurize, cut, weld, braze,
solder, drill, grind, or expose empty containers to heat, sparks or
open flames. Use only with adequate ventilation. Avoid breathing
vapor or mist.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Flammables-area. Storage under a nitrogen
blanket has been recommended. Containers should be dated when opened
and tested periodically for the presence of peroxides. Should
crystals form in a peroxidizable liquid, peroxidation may have
occurred and the product should be considered extremely dangerous. In
this instance, the container should only be opened remotely by
professionals. All peroxidizable substances should be stored away
from heat and light and be protected from ignition sources.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

**** SECTION 10 - STABILITY AND REACTIVITY ****
Chemical Stability:
Under normal storage conditions, peroxidizable compounds can form
and accumulate peroxides which may explode when subjected to heat or
shock. This material is most hazardous when peroxide levels are
concentrated by distillation or evaporation. DCPD will decompose to
cyclopentadiene at temperatures > 150C.
Conditions to Avoid:
Ignition sources, excess heat, evaporating to near dryness, prolonged
exposure to air, loss of inhibitor.
