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.
