First Aid Measures

Emergency procedures for chemical exposure incidents

Inhalation

Remove victim to fresh air and keep at rest in a position comfortable for breathing. Do not leave the victim unattended. Keep patient warm and at rest. Immediately seek medical attention. If breathing is difficult, give oxygen. If unconscious place in recovery position and seek medical advice. In the event of unconsciousness, apnea or cardiac arrest (no pulse) apply cardiopulmonary resuscitation.

Symptoms: Inhalation of very high concentrations may cause asphyxia, anesthesia, CNS depression (primarily fatigue, dizziness and loss of concentration, with collapse, coma and death in cases of severe overexposure), and possible cardiac sensitization.

Skin contact

If frostbite has not occurred, immediately flush affected area with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. If frostbite has occurred, seek medical attention immediately; do not rub the affected area or flush with water. To prevent further damage, do not attempt to remove frozen clothing from affected area. Get medical attention immediately if irritation persists.

Symptoms: Non-irritating to the skin. Dermal contact with rapidly evaporating liquid could result in freezing of the tissues or frostbite.

Eye contact

If eye tissue is frozen, seek medical attention immediately. If tissue is not frozen, thoroughly flush the eyes with large amounts of clean low-pressure water for at least 15 minutes, occasionally lifting the upper and lower eyelids. If irritation persists seek medical attention.

Symptoms: Skin or eye contact with rapidly evaporating liquid could result in freezing of the tissues or frostbite.

Ingestion

Ingestion is not a route of exposure for gases.

Immediate Medical Attention

Immediately seek medical attention (inhalation). If frostbite has occurred, seek medical attention immediately. If eye tissue is frozen, seek medical attention immediately.

Medical Treatment

Treat symptomatically. Treatment of overexposure should be directed at the control of symptoms and the clinical condition of the patient. Treat frost-bitten areas as needed.

05

Firefighting Measures

Extinguishing media, specific hazards, and firefighter protection

Suitable media

SMALL FIRE: Use dry chemical, CO2, water spray or regular foam. LARGE FIRE: Use water spray, water fog or regular foam. Do not use straight streams.

Unsuitable media

Do not extinguish a leaking gas fire unless leak can be stopped.

Specific hazards

May polymerize explosively when involved in a fire. Vapors may travel long distances along the ground before reaching a source of ignition and flashing back. Reacts with air to form peroxides.

Instructions

Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Do not direct water at source of leak or safety devices; icing may occur. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. Always stay away from tanks engulfed in fire. For massive fire, use unmanned hose holders or monitor nozzles; if this is impossible, withdraw from area and let fire burn. Move containers from fire area if it can be done without risk.

Firefighter Protection

Wear an approved positive pressure self-contained breathing apparatus and firefighter turnout gear.

06

Accidental Release Measures

Spill cleanup procedures, containment, and environmental protection

Emergency procedures

Use personal protective equipment. Eliminate all sources of ignition. Avoid direct contact with released material. Stay upwind. Keep non-involved personnel away from the area of spillage. Stop leak if you can do it without risk. Isolate area until gas has dispersed.

Environmental

An authoritative evaluation of environmental exposure and risk indicates that no special risk management practices are needed to control environmental release.

Cleanup methods

collect with non-combustible absorbent material, Let evaporate

Materials: non-combustible absorbent material

Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Do not handle near heat, sparks, or open flame. Do not enter storage areas unless adequately ventilated. Metal containers involved in the transfer of this material should be grounded and bonded. Bonding and grounding measures may not be enough if nonconductive flammables are involved. If exposure to liquid butadiene (unusual conditions, such as a leaking pressurized cylinder) were to occur, the rapid evaporation of this substance could cause severe cooling and damage to the skin in the form of frostbite. Check atmosphere for explosiveness and oxygen deficiencies. Wear recommended personal protective equipment. Handle empty containers with care; vapor residue may be flammable/explosive. Isolate, vent, drain, wash and purge systems or equipment before maintenance or repair. All equipment must conform to applicable electrical code. Use only non-sparking tools. Do not pressurize, cut, weld, braze solder, drill, or grind on containers. While moving cylinder, always keep in place removable valve cover. Securely chain cylinders when in use and protect against physical damage. Do not pressurize or expose empty containers to open flame, sparks, or heat. Do not enter areas where used or stored until adequately ventilated.

Storage

Keep storage containers clean, dry and free of oxygen. Store in accordance with the particular national regulations. Oxygen intrusion into the vessel headspace may support the formation of peroxides and promote popcorn polymer growth. Store in tightly closed containers segregated from oxidizers and other combustible material. Provide electrical equipment with spark resistant construction.

Fire prevention

Take precautionary measures against static discharge. Do not handle near heat, sparks, or open flame.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits.

Hands

Wear insulated gloves if contact with liquid is possible. The selected gloves must satisfy the European norm standard EN 511 for protection against the cold.

Eyes

Safety glasses are the minimum requirements. Use chemical type goggles and face shield when handling liquified gases. The selected goggles or glasses must satisfy the European norm standard EN 166.

Respiratory

When workers are facing concentrations above the exposure limit they must use appropriate certified respirators. Use only approved supplied air or self-contained breathing apparatus operated in positive pressure mode. If needed, wear a supplied air respirator conforming to a European norm standard such as EN 139 or equivalent. Wear a respirator conforming to EN 371 with Type AX filter designed for low boiling compounds.

Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

This material is stable when properly handled and stored.

Reactivity

1,3-butadiene may react with oxygen to form unstable butadiene peroxides. Butadiene peroxides are thermally unstable, shock sensitive and may lead to the formation of popcorn polymer.

Hazardous reactions

Polymerization may take place at elevated temperatures or in the presence of oxidizers. The formation of popcorn polymer can build sufficient mechanical force to rupture process equipment. Polymer may also plug safety venting devices.

Avoid

All sources of ignition, high temperature and oxygen intrusion into storage and transportation vessels. Elevated temperature or catalysis can cause violent rupture of containers.

Incompatible

Phenol, ethanol, chlorine dioxide, crotonaldehyde, nitric acid, oxygen and other strong oxidizers, and acetylide forming materials such as copper, magnesium, mercury, silver and monel. Contact may form violently explosive peroxides.

Decomposition

Explosive peroxides. 4-Vinylcyclohexene-1. Thermal decomposition : Note: Carbon dioxide, carbon monoxide, smoke, fumes and unburned hydrocarbons.
