International Chemical Safety Cards SALICYLIC ACID ICSC: 0563 SALICYLIC ACID 2-Hydroxybenzoic acid o-Hydroxybenzoic acid C7H6O3 / HOC6H4COOH Molecular mass: 138.1 CAS # 69-72-7 RTECS # VO0525000 ICSC # 0563 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Combustible. NO open flames. Carbon dioxide, water spray, powder. EXPLOSION Finely dispersed particles form explosive mixtures in air. Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE PREVENT DISPERSION OF DUST! INHALATION Cough. Sore throat (see Ingestion). Local exhaust or breathing protection. Fresh air, rest. Refer for medical attention. SKIN Redness. Protective gloves. Remove contaminated clothes. Rinse and then wash skin with water and soap. EYES Redness. Pain. 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 take to a doctor. INGESTION Nausea. Vomiting. Ear ringing. Do not eat, drink, or smoke during work. Rinse mouth. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting (extra personal protection: P2 filter respirator for harmful particles). Separated from strong oxidants.

International Chemical Safety Cards SALICYLIC ACID ICSC: 0563 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS CRYSTALLINE POWDER OR NEEDLE-SHAPED CRYSTALS. 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. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and by ingestion. INHALATION RISK: Evaporation at 20°C is negligible; a nuisance-causing concentration of airborne particles can, however, be reached quickly by dispersing powder. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. The substance may cause effects on the central nervous system and the acid-base balance in the body , resulting in delirium and tremors. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Sublimation point: 76°C Melting point: 159°C Relative density (water = 1): 1.4 Solubility in water, g/100 ml at 20°C: 0.2 Vapour pressure, Pa at 130°C: 114 Relative vapour density (air = 1): 4.8 Flash point: 157°C Auto-ignition temperature: 540°C Octanol/water partition coefficient as log Pow: 2.2
