TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Flammable.	NO open flames, NO sparks, and NO smoking.	Powder, alcohol-resistant foam, water spray, carbon dioxide.
EXPLOSION	Above 39°C explosive vapour/air mixtures may be formed. Risk of fire and explosion on contact with strong oxidants.	Above 39°C use a closed system, ventilation, and explosion-proof electrical equipment.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		AVOID ALL CONTACT!	IN ALL CASES CONSULT A DOCTOR!
•INHALATION	Sore throat. Cough. Burning sensation. Headache. Dizziness. Shortness of breath. Laboured breathing.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Half-upright position. Refer immediately for medical attention.
•SKIN	Pain. Redness. Skin burns. Blisters.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower for at least 15 minutes. Refer immediately for medical attention.
•EYES	Redness. Pain. Severe burns. Loss of vision.	Face shield or eye protection in combination with breathing protection.	Rinse with plenty of water (remove contact lenses if easily possible). Refer immediately for medical attention.
•INGESTION	Sore throat. Burning sensation. Abdominal pain. Vomiting. Shock or collapse.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. If within a few minutes after ingestion, one small glass of water may be given to drink Refer immediately for medical attention.

PHYSICAL STATE; APPEARANCE:
COLOURLESS LIQUID , WITH PUNGENT ODOUR.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
The substance is a weak acid. Reacts violently with strong oxidants causing fire and explosion hazard. Reacts violently with strong bases , strong acids and many other compounds. Attacks some forms of plastic rubber and coatings .

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 10 ppm as TWA; 15 ppm as STEL (ACGIH 2010).
EU OEL: 10 ppm; 25 mg/mł as TWA (EU 1991).
OSHA PEL: TWA 10 ppm (25 mg/m³)
NIOSH REL: TWA 10 ppm (25 mg/m³) ST 15 ppm (37 mg/m³)
NIOSH IDLH: 50 ppm See: 64197

ROUTES OF EXPOSURE:
Serious local effects by all routes of exposure. inhal. LC50/1 hour =5620 ppm -> LC50 4h =1405 ppm (3513 mg/m³, 3.5 mg/l) LD50 in rats 3310 mg/kg bw; oral LD50 in mice 4960 mg/kg bw;

INHALATION RISK:
A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is corrosive to the eyes, the skin and the respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema, but only after initial corrosive effects on eyes and/or airways have become manifest. 47 igs exposed for one hour to conc. up to 568 ppm of acetic acid developed bronchial constriction.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Lungs may be affected by repeated or prolonged exposure to an aerosol of this substance. Risk of tooth erosion upon repeated or prolonged exposure to an aerosol of this substance.
