Dicyclopentadiene emergency treatment

Leakage emergency treatment

Cut off the fire. Emergency personnel should wear gas masks and general fire protective clothing. Sweep carefully, place in a bag and transfer to a safe place. Such as a large amount of leakage, collection and recycling or harmless disposal after waste.

Protective measures

Respiratory protection: Wear a mask when possible contact with toxins.

Eye protection: Generally no special protection is required.

Body protection: Wear antistatic work clothes.

Hand protection: Wear protective gloves if necessary.

Others: Smoking is strictly prohibited on site. Shower and change after work. Maintain good hygiene.
