	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Above 67°C explosive vapour/air mixtures may be formed.	NO open flames. Above 67°C use a closed system and ventilation.	Use powder, AFFF, foam, carbon dioxide. In case of fire: keep drums, etc., cool by spraying with water.

AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Burning sensation. Cough. Nausea. Headache. Shortness of breath. Dizziness.	Use ventilation, local exhaust or breathing protection.	Fresh air, rest. Half-upright position. Refer for medical attention.
Skin	MAY BE ABSORBED! Redness. Pain.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower. Refer for medical attention .
Eyes	Watering of the eyes. Redness. Pain. Blurred vision. Severe deep burns.	Wear safety goggles 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	Abdominal pain. Diarrhoea. Vomiting. Burning sensation.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention .

BENZYL CHLORIDE

ICSC: 0016

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance COLOURLESS LIQUID WITH PUNGENT ODOUR. Physical dangers Chemical dangers The substance polymerizes under the influence of all common metals except nickel and lead. This produces corrosive fumes (hydrogen chloride - see ICSC 0163). This generates fire or explosion hazard. On combustion, forms toxic and corrosive fumes of hydrogen chloride. Reacts vigorously with strong oxidants. Attacks many metals in the presence of water.	Formula: C₇H₇Cl / C₆H₅CH₂Cl Molecular mass: 126.6 Boiling point: 179°C Melting point: ~-43°C Relative density (water = 1): 1.1 Solubility in water, g/100ml: <0.1 (none) Vapour pressure, Pa at 20°C: 120 Relative vapour density (air = 1): 4.4 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 67°C c.c. Auto-ignition temperature: 585°C Explosive limits, vol% in air: 1.1-14.0 Octanol/water partition coefficient as log Pow: 2.3

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Effects of short-term exposure The substance is corrosive to the eyes. The vapour is irritating to the eyes, skin and respiratory tract. Inhalation of the vapour or aerosol may cause lung oedema. See Notes. The substance may cause effects on the central nervous system. This may result in unconsciousness.	Inhalation risk A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C , on spraying much faster. Effects of long-term or repeated exposure The substance may have effects on the liver and kidneys. This may result in tissue lesions. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C , on spraying much faster.

Effects of long-term or repeated exposure
The substance may have effects on the liver and kidneys. This may result in tissue lesions. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

OCCUPATIONAL EXPOSURE LIMITS
MAK: skin absorption (H); carcinogen category: 2

ENVIRONMENT
The substance is toxic to aquatic organisms.

NOTES
Depending on the degree of exposure, periodic medical examination is suggested. 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. Immediate administration of an appropriate inhalation therapy by a doctor, or by an authorized person, should be considered. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert.
