SECTION 4: FIRST AID MEASURES
4.1. Description of First-aid Measures
|
First-aid Measures General: Never give anything by mouth to an unconscious person. If you feel unwell, seek medical advice (show the label where possible). If frostbite or freezing occurs, immediately flush with plenty of lukewarm water to GENTLY warm the affected area. Do not use hot water. Do not rub affected area. Get immediate medical attention. |
|
First-aid Measures After Inhalation: When symptoms occur: go into open air and ventilate suspected area. Remove to fresh air and keep at rest in a position comfortable for breathing. Call a POISON CENTER/doctor/physician if you feel unwell. |
|
First-aid Measures After Skin Contact: Remove contaminated clothing. Drench affected area with water for at least 15 minutes. Obtain medical attention if irritation persists. Thaw frosted parts with lukewarm water. Do not rub affected area. |
|
First-aid Measures After Eye Contact: Rinse cautiously with water for several minutes. Remove contact lenses, if present and easy to do. Continue rinsing. Obtain medical attention if irritation persists. |
|
First-aid Measures After Ingestion: Rinse mouth. Do NOT induce vomiting. Get immediate medical attention. |
4.2. Most Important Symptoms and Effects Both Acute and Delayed
|
Symptoms/Injuries: May cause frostbite on contact with the liquid. Natural Gas is an asphyxiant. Lack of oxygen can be fatal. |
|
Symptoms/Injuries After Inhalation: Gas can be toxic as a simple asphyxiant by displacing oxygen from the air. Asphyxia by lack of oxygen: risk of death. May cause drowsiness or dizziness. |
|
Symptoms/Injuries After Skin Contact: Contact with the liquid may cause cold burns/frostbite. |
|
Symptoms/Injuries After Eye Contact: This gas is non-irritating; but direct contact with liquefied/pressurized gas or frost particles may produce severe and possibly permanent eye damage from freeze burns. |
|
Symptoms/Injuries After Ingestion: Ingestion is not considered a potential route of exposure. Non-irritating, but solid and liquid forms of this material and pressurized gas may cause freeze burns. |
|
Chronic Symptoms: None expected under normal conditions of use. |
4.3. Indication of Any Immediate Medical Attention and Special Treatment Needed
If exposed or concerned, get medical advice and attention. If medical advice is needed, have product container or label at hand. This product contains light hydrocarbon material, which is associated with cardiac sensitization following very high exposures or
with concurrent exposure to high stress levels or heart-stimulating substances like epinephrine and catecholamines. Careful consideration should be applied preceeding administration of epinehpherine or similar heart stimulating substances.
SECTION 5: FIRE-FIGHTING MEASURES
5.1. Extinguishing Media
|
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, water spray, fog. |
|
Unsuitable Extinguishing Media: Do not use a heavy water stream. Use of heavy stream of water may spread fire. |
5.2. Special Hazards Arising From the Substance or Mixture
|
Fire Hazard: Extremely flammable gas. |
|
Explosion Hazard: May form flammable/explosive vapor-air mixture. Heating may cause an explosion. Heat may build pressure, rupturing closed containers, spreading fire and increasing risk of burns and injuries. |
|
Reactivity: Hazardous reactions will not occur under normal conditions. |
5.3. Advice for Firefighters
|
Precautionary Measures Fire: Exercise caution when fighting any chemical fire. |
|
Firefighting Instructions: Leaking gas fire: Do not extinguish, unless leak can be stopped safely. In case of leaking gas fire, eliminate all ignition sources if safe to do so. Use water spray or fog for cooling exposed containers. In case of major fire and large quantities: Evacuate area. Fight fire remotely due to the risk of explosion. |
|
Protection During Firefighting: Do not enter fire area without proper protective equipment, including respiratory protection. |
|
Hazardous Combustion Products: Carbon oxides (CO, CO2), Hydrocarbons. |
|
Other Information: Do not allow run-off from fire fighting to enter drains or water courses. |
SECTION 6: ACCIDENTAL RELEASE MEASURES
6.1. Personal Precautions, Protective Equipment and Emergency Procedures
|
General Measures: Use special care to avoid static electric charges. Eliminate every possible source of ignition. Keep away from flames, heat, sparks. - No smoking. Use only outdoors or in a well-ventilated area. Ruptured cylinders may rocket. Do not allow |
6.1.1. For Non-Emergency Personnel
|
Protective Equipment: Use appropriate personal protective equipment (PPE). |
|

|
Emergency Procedures: Ventilate area. |
6.2. Environmental Precautions
Prevent entry to sewers and public waters. Avoid release to the environment.
6.3. Methods and Materials for Containment and Cleaning Up
|
For Containment: Notify authorities if liquid enters sewers or public waters. Use only non-sparking tools. |
|
Methods for Cleaning Up: Clean up spills immediately and dispose of waste safely. Isolate area until gas has dispersed. Use water spray to disperse vapors. For water based spills contact appropriate authorities and abide by local regulations for |
6.4. Reference to Other Sections
See Section 8 for exposure controls and personal protection.
SECTION 7: HANDLING AND STORAGE
7.1. Precautions for Safe Handling
|
Additional Hazards When Processed: Handle empty containers with care because residual vapors are flammable. Extremely flammable gas. Do not pressurize, cut, or weld containers. Do not puncture or incinerate container. Liquid gas can cause frost-type |
|
Precautions for Safe Handling: Keep away from heat, sparks, open flames, hot surfaces. - No smoking. Avoid breathing gas, spray. Use only outdoors or in a well-ventilated area. |
|
Hygiene Measures: Handle in accordance with good industrial hygiene and safety procedures. Wash hands and other exposed areas with mild soap and water before eating, drinking, or smoking and again when leaving work. Do not eat, drink or smoke |
7.2. Conditions for Safe Storage, Including Any Incompatibilities
|
Technical Measures: Proper grounding procedures to avoid static electricity should be followed. Comply with applicable regulations. Use explosion proof equipment. |
|
Storage Conditions: Store in a dry, cool and well-ventilated place. Keep container closed when not in use. Keep in fireproof place. Keep/Store away from extremely high or low temperatures, ignition sources, direct sunlight, incompatible materials. Store |
|
