Fresh air, rest.

Remove contaminated clothes. Rinse and then wash skin with water and soap.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Rinse mouth. Refer for medical attention .

LIQUID OR SOLID: Irritating to skin and eyes. (USCG, 1999)

Immediate First Aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR if necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention.

Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.

FLAMMABLE. Flashback along vapor trail may occur. Vapor may explode if ignited in an enclosed area. (USCG, 1999)

Use water in large amounts, foam, carbon dioxide, powder. In case of fire: keep drums, etc., cool by spraying with water.

Remove all ignition sources. Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable containers. Then store and dispose of according to local regulations.

Remove all ignition sources. Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Sweep spilled substance into covered sealable containers. Then store and dispose of according to local regulations.

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas; Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided; Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations.

NO open flames, NO sparks and NO smoking. Above 32°C use a closed system, ventilation and explosion-proof electrical equipment. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.

Store only if stabilized. Store in an area without drain or sewer access. Fireproof. Cool. Keep in the dark. Separated from strong oxidants.Keep container tightly closed in a dry and well-ventilated place. Containers which are opened must be carefully resealed and kept upright to prevent leakage.

The substance can form explosive peroxides. Decomposes above 170°C . Reacts with oxidants.

Stable under recommended storage conditions. Contains the following stabilizer(s): BHT (0.05 %)

Flammable; fire hazardDICYCLOPENTADIENE may react vigorously with oxidizing agents. May react exothermically with reducing agents to release hydrogen gas. Can undergo exothermic polymierization reactions In the presence of various catalysts (such as acids) or initiators, if subjected to heat for prolonged periods, or if contaminated. Many undergo autoxidation upon exposure to the air to form explosive peroxides.

A harmful contamination of the air will be reached rather slowly on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

AEROBIC: Dicyclopentadiene, present at 100 mg/L, reached 0% of its theoretical BOD in 2 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test (OECD 301C) which classified the compound as not readily biodegradable(1). Using OECD Guideline 301F (Ready Biodegradability: Manometric Respirometry Test) with an activated sludge inoculum, a petroleum-cracked stream containing 29% dicyclopentadiene had 0% biodegradation of the dicyclopentadiene fraction after 28 days(2). Very slow biotransformation of dicyclopentadiene was observed when it was inoculated with soil and water obtained from the Rocky Mountain Arsenal(3). Two field studies in Alberta, Canada found biodegradation rates of 37-57% in 266 days and not appreciable to 60% in 116 days(4).

A BCF range of 58.9-384 was measured in fish for dicyclopentadiene using OECD method 305C and carp (Cyprinus carpio) which were exposed over an 8-week period(1). According to a classification scheme(3), this BCF range indicates that bioconcentration in aquatic organisms is moderate to high(SRC). A BCF of 53 was measured in bluegill fish (Lepomis macrochirus) using a concentration of 1 mg/L; however, a "disregarded study" flag was applied for environmental fate assessment as the exposure period was only 96 hours(4).

Using a structure estimation method based on molecular connectivity indices(1), the Koc of dicyclopentadiene can be estimated to be 1500(SRC). According to a classification scheme(2), this estimated Koc value suggests that dicyclopentadiene is expected to have low mobility in soil.

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
