Description of first aid measures
If inhaledArtificial respiration may be needed. Refer for medical attention.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Refer for medical attention .
Most important symptoms and effects, both acute and delayed
Inhalation or ingestion causes flushing of the face, pulsatile headache, disturbing tachycardia, cyanosis (methemoglobinemia), weakness, confusion, restlessness, faintness, and collapse. Contact with eyes or skin causes irritation. (USCG, 1999)
Indication of any immediate medical attention and special treatment needed
Absorption, Distribution and ExcretionAmyl nitrite vapors are absorbed rapidly through the pulmonary alveoli, manifesting therapeutic effects within one minute after inhalation.
Extinguishing media
Excerpt from ERG Guide 129 [Flammable Liquids (Water-Miscible / Noxious)]: CAUTION: All these products have a very low flash point: Use of water spray when fighting fire may be inefficient. SMALL FIRE: Dry chemical, CO2, water spray or alcohol-resistant foam. Do not use dry chemical extinguishers to control fires involving nitromethane (UN1261) or nitroethane (UN2842). LARGE FIRE: Water spray, fog or alcohol-resistant foam. Do not use straight streams. Move containers from fire area if you can do it without risk. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: 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. 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. (ERG, 2016)
Specific Hazards Arising from the Chemical
Special Hazards of Combustion Products: Toxic oxides of nitrogen are formed. Behavior in Fire: Containers may explode. (USCG, 1999)
Advice for firefighters
Wear self-contained breathing apparatus for firefighting if necessary.
NFPA 704
Personal precautions, protective equipment and emergency procedures
Avoid dust formation. Avoid breathing mist, gas or vapours.Avoid contacting with skin and eye. Use personal protective equipment.Wear chemical impermeable gloves. Ensure adequate ventilation.Remove all sources of ignition. Evacuate personnel to safe areas.Keep people away from and upwind of spill/leak.
Environmental precautions
Evacuate danger area! Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Ventilation. Remove all ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent. Then store and dispose of according to local regulations. Do NOT wash away into sewer.
Methods and materials for containment and cleaning up
Collect and arrange disposal. Keep the chemical in suitable and closed containers for disposal. Remove all sources of ignition. Use spark-proof tools and explosion-proof equipment. Adhered or collected material should be promptly disposed of, in accordance with appropriate laws and regulations.
Precautions for safe handling
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. Separated from strong oxidants. Cool. Well closed.

Exposure controls
Ensure adequate ventilation. Handle in accordance with good industrial hygiene and safety practice. Set up emergency exits and the risk-elimination area.
Individual protection measures
Eye/face protectionWear tightly fitting safety goggles with side-shields conforming to EN 166(EU) or NIOSH (US).
Wear fire/flame resistant and impervious clothing. Handle with gloves. Gloves must be inspected prior to use. Wash and dry hands. The selected protective gloves have to satisfy the specifications of EU Directive 89/686/EEC and the standard EN 374 derived from it.
If the exposure limits are exceeded, irritation or other symptoms are experienced, use a full-face respirator.

Information on basic physicochemical properties
- Physical state
Amyl nitrite is a clear colorless to yellowish liquid with a fragrant, fruity odor and pungent aromatic taste. Flash point below 73°F. Boiling point 205-210°F (96-99°C). Less dense than water and insoluble in water. Hence floats on water. Vapors are heavier than air. Produces toxic oxides of nitrogen during combustion. Used in medicine and to make other chemicals.
- ColourClear, yellowish liquid
- Odour
no data available
- Melting point/freezing point
91°C(lit.)
- Boiling point or initial boiling point and boiling range
104°C(lit.)
- Flammability
Highly flammable. Many reactions may cause fire or explosion. Heating will cause rise in pressure with risk of bursting.

Reactivity
May explode on heating. Decomposes on burning. This produces toxic gases including nitrogen oxides. Reacts with oxidants. This generates fire and explosion hazard.
Chemical stability
no data available
Possibility of hazardous reactions
The vapour is heavier than air and may travel along the ground; distant ignition possible.AMYL NITRITE is an oxidizing agent. May begin a vigorous reaction that culminates in a detonation if mixed with reducing agents, including hydrides, sulfides and nitrides.

Disposal methods
ProductThe material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.
Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
