TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible.
NO open flames.
Powder, water spray, foam, carbon dioxide.
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.

EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation Cough. Sore throat.
Ventilation (not if powder).
Fresh air, rest. Refer for medical attention.
Skin Redness.
Protective gloves.
Rinse skin with plenty of water or shower. Refer for medical attention.
Eyes Redness. Pain.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Nausea. Vomiting.
Do not eat, drink, or smoke during work.
Rinse mouth. Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. (extra personal protection: P2 filter respirator for harmful particles).

2-(ACETYLOXY)BENZOIC ACID ICSC: 0822
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO WHITE CRYSTALS OR WHITE CRYSTALLINE POWDER, WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
The solution in water is a weak acid.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 5 mg/m^3 (ACGIH 1997). MAK not established.
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation and by ingestion.

INHALATION RISK:
Evaporation at 20C is negligible; a harmful concentration of airborne particles can, however, be reached quickly when dispersed, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes, the skin, and the respiratory tract. The substance may cause effects on the blood and central nervous system, if ingested in large amounts.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Animal tests show that this substance possibly causes toxic effects upon human reproduction.
PHYSICAL PROPERTIES
Decomposes below boiling point at 140C
Melting point: 135C
Density: 1.4 g/cm^3
Solubility in water: poor (0.25 g/100 ml at 15C)
Vapour pressure, Pa at 25C: about 0.004
Octanol/water partition coefficient as log Pow: 1.19
