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

AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat. Laboured breathing. Shortness of breath.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.
Skin	Redness. Pain. Skin burns.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Redness. Pain. Burns.	Wear 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		Do not eat, drink, or smoke during work.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Evacuate danger area! Consult an expert! Personal protection: gas-tight chemical protection suit including self-contained breathing apparatus. Ventilation. NEVER direct water jet on liquid. Remove gas with fine water spray. Do NOT absorb in saw-dust or other combustible absorbents.	According to UN GHS Criteria Transportation UN Classification UN Hazard Class: 2.3; UN Subsidiary Risks: 8
STORAGE
Separated from incompatible materials. See Chemical Dangers. Cool. Keep in a well-ventilated room.

NITROSYL CHLORIDE

ICSC: 1580

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance YELLOW GAS WITH PUNGENT ODOUR. Physical dangers The gas is heavier than air and may accumulate in lowered spaces causing a deficiency of oxygen. Chemical dangers Decomposes on heating and on contact with water. This produces toxic and corrosive fumes including hydrogen chloride and nitrogen oxides. Reacts violently with strong oxidants. Attacks metals. The substance is a strong oxidant. It reacts with combustible and reducing materials.	Formula: ClNO Molecular mass: 65.46 Boiling point: -5 - -6°C Melting point: -64°C Density: g/cm³ Solubility in water: reaction Vapour pressure, kPa at 20°C: 340 Relative vapour density (air = 1): 2.3 Relative density of the vapour/air-mixture at 20°C (air = 1): 5.2

EXPOSURE & HEALTH EFFECTS
Routes of exposure 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.	Inhalation risk A harmful concentration of this gas in the air will be reached very quickly on loss of containment. Effects of long-term or repeated exposure

EXPOSURE & HEALTH EFFECTS

Routes of exposure

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.

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

Effects of long-term or repeated exposure

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is harmful to aquatic organisms.

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 are therefore essential. Rinse contaminated clothing with plenty of water because of fire hazard. Check oxygen content before entering area. High concentrations in the air cause a deficiency of oxygen with the risk of unconsciousness or death.
