TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Not combustible. Gives off irritating or toxic fumes (or gases) in a fire.		NO water. In case of fire in the surroundings, use appropriate extinguishing media.
EXPLOSION			In case of fire: keep cylinder cool by spraying with water. NO direct contact with water.

EXPOSURE		AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
Inhalation	Sore throat. Cough. Burning sensation. Shortness of breath. Laboured breathing. Symptoms may be delayed. See Notes.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Pain. Redness. Blisters. Skin burns. ON CONTACT WITH LIQUID: FROSTBITE.	Cold-insulating gloves. Protective clothing.	ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
Eyes	Pain. Redness. Severe deep burns. Loss of vision.	Wear face shield or eye protection in combination with breathing protection.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion

SPILLAGE DISPOSAL	PACKAGING & LABELLING
Evacuate danger area! Consult an expert! Ventilation. Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus.	Do not transport with food and feedstuffs. EC Classification Symbol: T+; R: 14-26/28-34; S: (1/2)-9-26-28-36/37/39-45 UN Classification UN Hazard Class: 2.3; UN Subsidiary Risks: 8 GHS Classification

EMERGENCY RESPONSE	SAFE STORAGE

IMPORTANT DATA

Physical State; Appearance
GAS OR COLOURLESS FUMING LIQUID WITH PUNGENT ODOUR.

Physical dangers
The gas is heavier than air.

Chemical dangers
Decomposes on heating. This produces toxic and corrosive fumes including hydrogen chloride. Reacts violently with water and moist air. This produces hydrogen chloride and boric acid. Reacts violently with aniline, phosphine, alcohols, oxygen and organic matter such as grease. Attacks many metals in the presence of water.

Occupational exposure limits
TLV (NOT-ESTABLISHED):.

Routes of exposure
The substance can be absorbed into the body by inhalation.

Inhalation risk
A harmful concentration of this gas in the air will be reached very quickly on loss of containment.

Effects of short-term exposure
The substance is corrosive to the eyes, skin and respiratory tract. Inhalation of this gas may cause lung oedema. See Notes. Rapid evaporation of the liquid may cause frostbite. Exposure at high levels could cause death. The effects may be delayed. Medical observation is indicated.

Effects of long-term or repeated exposure

PHYSICAL PROPERTIES	ENVIRONMENTAL DATA
Boiling point: 12.5°C Melting point: -107°C Relative density (water = 1): 1.35 Solubility in water: reaction Vapour pressure, kPa at 20°C: 150 Relative vapour density (air = 1): 4.03

NOTES

Reacts violently with fire extinguishing agents such as water.
The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort.
Rest and medical observation is therefore essential.
Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
