Prevention
P201 Obtain special instructions before use. P202 Do not handle until all safety precautions have been read and understood. P210 Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking. P243 Take action to prevent static discharges. P280 Wear protective gloves/ protective clothing/ eye protection/ face protection/ hearing protection. Contaminated work clothing should not be allowed out of the workplace.
Response
P308 + P313 IF exposed or concerned: Get medical advice/ attention. P377 Leaking gas fire: Do not extinguish, unless leak can be stopped safely. P381 In case of leakage, eliminate all ignition sources.
Storage
P410 + P403 Protect from sunlight. Store in a well-ventilated place. P405 Store locked up.
Disposal
P501 Dispose of contents and container to appropriate waste site or reclaimer in accordance with local and national regula- tions.
Other hazards which do not result in classification
Vapours may cause drowsiness and dizziness. Slightly irritating to respiratory system. Exposure to rapidly expanding gases may cause frost burns to eyes and/or skin. Vapours may be irritating to the eye. Possibility of organ or organ system damage from prolonged exposure; see Section 11 for details. Target organ(s): Blood forming organs Reproductive system. This material is a static accumulator. Even with proper grounding and bonding, this material can still accumulate an electrostatic charge. If sufficient charge is allowed to accumulate, electrostatic discharge and ignition of flammable air- vapour mixtures can occur. Highly reactive. May form explosive peroxides. The vapour is heavier than air, spreads along the ground and distant ignition is possible. May form flammable/explosive vapour-air mixture.
