SECTION 4: First aid measures
Description of necessary first-aid measures
Fresh air, rest. Refer immediately for medical attention.
Take off contaminated clothing immediately. Wash off with soap and plenty of water. Consult a doctor.
Rinse with pure water for at least 15 minutes. Consult a doctor.
Rinse mouth with water. Do not induce vomiting. Never give anything by mouth to an unconscious person. Call a doctor or Poison Control Center immediately.
Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 119 [Gases - Toxic - Flammable]: TOXIC; may be fatal if inhaled or absorbed through skin. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Arsine and related compounds
SECTION 5: Firefighting measures
Suitable extinguishing media
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide. Special protective equipment for fire-fighters: Wear self contained breathing apparatus for fire fighting if necessary. Use water spray to cool unopened containers.
Specific hazards arising from the chemical
Excerpt from ERG Guide 119 [Gases - Toxic - Flammable]: Flammable; may be ignited by heat, sparks or flames. May form explosive mixtures with air. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Vapors from liquefied gas are initially heavier than air and spread along ground. Vapors may travel to source of ignition and flash back. Some of these materials may react violently with water. Cylinders exposed to fire may vent and release toxic and flammable gas through pressure relief devices. Containers may explode when heated. Ruptured cylinders may rocket. Runoff may create fire or explosion hazard. (ERG, 2016)
Special protective actions for fire-fighters
Shut off supply; if not possible and no risk to surroundings, let the fire burn itself out. In other cases extinguish with carbon dioxide, dry powder. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Remove all ignition sources. Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation.
Environmental precautions
Evacuate danger area! Remove all ignition sources. Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation.
Methods and materials for containment and cleaning up
Personal precautions: Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Methods for cleaning up: Wipe up with absorbent material (e.g. cloth, fleece).
SECTION 7: Handling and storage
Precautions for safe handling
NO open flames, NO sparks and NO smoking. Closed system, ventilation, explosion-proof electrical equipment and lighting. Handling in a well ventilated place. Wear suitable protective clothing. Avoid contact with skin and eyes. Avoid formation of dust and aerosols. Use non-sparking tools. Prevent fire caused by electrostatic discharge steam.
Conditions for safe storage, including any incompatibilities
Fireproof.Keep container tightly closed in a dry and well-ventilated place. Contents under pressure.

SECTION 9: Physical and chemical properties and safety characteristics
-
Physical state：
Germane is a colorless gas with a pungent odor. It is flammable. The gas is heavier than air and a flame can flash back to the source of leak very easily. It is toxic by inhalation. Prolonged exposure of the containers to fire or intense heat may result in their violent rupturing and rocketing. It is used in making electronics.

SECTION 10: Stability and reactivity
Reactivity
The substance may ignite spontaneously on contact with air. Heating may cause violent combustion or explosion. Reacts with halogens and oxidants. This generates fire and explosion hazard.
Chemical stability
no data available
Possibility of hazardous reactions
The gas is heavier than air and may travel along the ground; distant ignition possible.Hydrides, such as GERMANE, are reducing agents and react rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols. Hydrides are incompatible with acids, alcohols, amines, and aldehydes.
Conditions to avoid
no data available
Incompatible materials
Ignites spontaneously in air.
Hazardous decomposition products
Hazardous decomposition products formed under fire conditions. - Germanium oxides
