FLAMMABLE TOXIC LIQUEFIED GAS
1. Characteristics
- Can spontaneously lead to violent reaction.
- Forms explosive mixture with air.
- Toxic by inhalation.
2. Hazards
- Exposure to heat, light, mechanical shock or contact with other chemicals lead to spontaneous rise in pressure or self ignition.
- Gives off toxic or irritant gases or fumes when burning.
- Heating of container(s) will cause pressure rise with risk of bursting and immediate release of expanding toxic vapour cloud (risk of BLEVE) which may ignite, leading to explosion (VCE) and creation of a pressure wave.
- The gas may be invisible and may enter sewers, basements or confined spaces.
- Heat may destroy stabiliser. Seek specialist advice.
3. Personal Protection
- Self contained breathing apparatus.
- Protect personnel from radiated heat with water fog curtain or other heat protective measures.
4. Intervention Actions
4.1 General
- No smoking, eliminate ignition sources.
- PUBLIC SAFETY HAZARD - Warn people nearby to stay indoors with doors and windows closed. Stop any ventilation. Consider evacuation of people in immediate danger.
- Work from protected position to reduce risk to personnel. Use unmanned monitors or lances.
- Keep upwind. Put on protective equipment before entering danger area.
- Minimise number of personnel in risk area.
- Warn people to leave and not to re-enter basements, sewers or other confined spaces.
4.2 Spillage
- Stop leaks if possible.
- Check explosive limits.
- Use low sparking hand tools and intrinsically safe equipment.
- Knock down or disperse gas cloud with water spray.
- If substance has entered a water course or sewer, inform the responsible authority.
- Ventilate sewers and basements where there is no risk to personnel or public.
4.3 Fire (involving the substance)
- Keep container(s) cool with water.
- Cut off gas supply if safe to do so.
- Do NOT extinguish leaking gas flame unless ABSOLUTELY necessary.
- Extinguish with water fog (spray) or dry powder.
- Do not use water jet to extinguish.
- Use water spray to knock down fire fumes if possible.
- Avoid unnecessary run-off of extinguishing media which may cause pollution.
5. First Aid
- If substance has got into eyes, wash out with water for at least 15 minutes and seek immediate medical attention.
- Persons who have been in contact with the substance or have inhaled fumes should get immediate medical attention. Pass on all available product information.
- In case of burns, immediately cool affected skin for as long as possible with cold water. Do not remove clothing adhering to skin.
- Mouth to mouth resuscitation should be avoided. Use alternative methods, preferably with oxygen or compressed air driven apparatus.
6. Essential Precautions For Product Recovery
- Do not use standard recovery equipment. Seek specialist advice immediately.
7. Precautions After Intervention
7.1 Undressing
- Remove contaminated clothing as soon as possible and before leaving incident.
7.2 Equipment Clean Up
- Seek specialist advice before leaving incident.
