2-Hydroxybenzoic acid o-Hydroxybenzoic acid

CAS #: 69-72-7

EC Number: 200-712-3

	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Finely dispersed particles form explosive mixtures in air.	NO open flames. Closed system, dust explosion-proof electrical equipment and lighting. Prevent deposition of dust.	Use water spray, carbon dioxide, powder. In case of fire: keep drums, etc., cool by spraying with water.

PREVENT DISPERSION OF DUST!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	Cough. Sore throat.	Use local exhaust or breathing protection.	Fresh air, rest. Refer for medical attention.
Skin		Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain.	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	Nausea. Vomiting. Ringing in the ears. Symptoms may appear if large amounts are accidentally ingested. See Effects of short-term exposure	Do not eat, drink, or smoke during work.	Rinse mouth. Refer immediately for medical attention.

SPILLAGE DISPOSAL	CLASSIFICATION & LABELLING
Personal protection: particulate filter respirator adapted to the airborne concentration of the substance, protective clothing, protective gloves and safety goggles. If appropriate, moisten first to prevent dusting. Sweep spilled substance into covered containers. Then store and dispose of according to local regulations.	According to UN GHS Criteria Harmful if swallowed Causes serious eye damage Suspected of damaging fertility or the unborn child Transportation UN Classification
STORAGE
Separated from incompatible materials. See Chemical Dangers.

SALICYLIC ACID

ICSC: 0563

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance ODOURLESS WHITE-TO-YELLOW POWDER. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers The solution in water is a weak acid. Reacts with strong oxidants, fluorine, iodine, lead and iron. Decomposes on heating. This produces carbon dioxide and other gaseous products.	Formula: C₇H₆O₃ / HOC₆H₄COOH Molecular mass: 138.1 Melting point: 159°C Sublimation point: 76°C Boiling point: 256°C (sublimes) Boiling point at 2.7kPa: 211°C Relative density (water = 1): 1.4 Solubility in water, g/100ml at 20°C: 0.2 (slightly soluble) Vapour pressure, Pa at 25°C: 0.02 Relative vapour density (air = 1): 4.8 Flash point: 157°C c.c. Auto-ignition temperature: 570°C 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, by ingestion and through the skin. Effects of short-term exposure The substance is severely irritating to the eyes. The substance may cause effects on the central nervous system, acid-base balance in the body and gastrointestinal tract when ingested in large amounts. This may result in delirium, tremors and coma.	Inhalation risk No indication can be given about the rate at which a harmful concentration of this substance in the air is reached when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. Animal tests show that this substance possibly causes toxicity to human reproduction or development.
