SECTION 4: First-aid measures
4.1 Description of necessary first-aid measures
If inhaled
Fresh air, rest. Refer for medical attention.
Following skin contact
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
Following eye contact
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Following ingestion
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.
4.2 Most important symptoms/effects, acute and delayed
Inhalation causes intense analgesia; concentrations of over 40-60% cause loss of consciousness preceded by hysteria. Contact of liquid with eyes or skin causes frostbite burn. (USCG, 1999)
Excerpt from ERG Guide 122 [Gases - Oxidizing (Including Refrigerated Liquids)]: Vapors may cause dizziness or asphyxiation without warning. Contact with gas or liquefied gas may cause burns, severe injury and/or frostbite. Fire may produce irritating and/or toxic gases. (ERG, 2016)
4.3 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 if 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. Nitrogen Oxides (NOx) and Related Compounds
SECTION 5: Fire-fighting measures
5.1 Suitable extinguishing media
Suitable extinguishing media: Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.
5.2 Specific hazards arising from the chemical
Behavior in Fire: Will support combustion, and may increase intensity of fire. Containers may explode when heated. (USCG, 1999)
Excerpt from ERG Guide 122 [Gases - Oxidizing (Including Refrigerated Liquids)]: Substance does not burn but will support combustion. Some may react explosively with fuels. May ignite combustibles (wood, paper, oil, clothing, etc.). Vapors from liquefied gas are initially heavier than air and spread along ground. Runoff may create fire or explosion hazard. Containers may explode when heated. Ruptured cylinders may rocket. (ERG, 2016)
5.3 Special protective actions for fire-fighters
In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water. Combat fire from a sheltered position.
SECTION 6: Accidental release measures
6.1 Personal precautions, protective equipment and emergency procedures
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. If liquid: do NOT absorb in saw-dust or other combustible components.
6.2 Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. If liquid: do NOT absorb in saw-dust or other combustible components.
6.3 Methods and materials for containment and cleaning up
ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Evacuate personnel to safe areas; Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains; Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations.
SECTION 7: Handling and storage
7.1 Precautions for safe handling

SECTION 9: Physical and chemical properties and safety characteristics
| Physical state | Nitrous oxide is a colorless, sweet-tasting gas. It is also known as "laughing gas". Continued breathing of the vapors may impair the decision making process. It is noncombustible but it will accelerate the burning of combustible material in a fire. It is soluble in water. Its vapors are heavier than air. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket. It is used as an anesthetic, in pressure packaging, and to manufacture other chemicals. |
|---|---|
| Colour | Colorless gas [Note: Shipped as a liquified compressed gas] |
| Odour | Slightly sweetish |
| Melting point/freezing point | -91ºC(lit.) |
| Boiling point or initial boiling point and boiling range | ?88°C(lit.) |
| Flammability | Nonflammable Gas, but supports combustion at elevated temperatures. |
| Lower and upper explosion limit/flammability limit | no data available |
| Flash point | no data available |
| Auto-ignition temperature | no data available |
| Decomposition temperature | no data available |
| pH | no data available |
| Kinematic viscosity | 0.0145 cP at 25 deg C at 101.325 KPa (gas) |
| Solubility | 0.1 % at 77° F (NIOSH, 2016) |
| Partition coefficient n-octanol/water | no data available |
| Vapour pressure | 51.7 mm Hg ( 21 °C) |
| Density and/or relative density | 1.46 g/cm3 |
| Relative vapour density | 1.53 (15 °C, vs air) |
| Particle characteristics | no data available |
SECTION 10: Stability and reactivity
10.1 Reactivity
The substance is a strong oxidant above 300°C. It reacts violently with reducing agents and some combustible substances. This generates fire and explosion hazard.
10.2 Chemical stability
Stable under recommended storage conditions.
10.3 Possibility of hazardous reactions
Spontaneous ignition occurs when nitrous oxide and lithium hydride or hydrazine are mixed.The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen.NITROUS OXIDE is a weak oxidizing agent. Nonflammable but supports combustion. Can explode at high temperature (after vaporization). Vapors can undergo a violent reaction with aluminum, boron, hydrazine, lithium hydride, phenyllithium, phosphine, sodium, tungsten carbide [Bretherick, 5th ed., 1995, p. 1686]. Contact of the cold liquefied gas with water may result in vigorous or violent boiling. If the water is hot, a liquid "superheat" explosion may occur. Pressures may build to dangerous levels if liquefied gas contacts water in a closed container [Handling Chemicals Safely 1980].
