TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Extremely flammable. Heating will cause rise in pressure with risk of bursting.	NO open flames, NO sparks, and NO smoking.	Alcohol-resistant foam, foam , water spray .
EXPLOSION	Vapour/air mixtures are explosive.	Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). Do NOT use compressed air for filling, discharging, or handling. Use non-sparking handtools.	In case of fire: keep drums, etc., cool by spraying with water.

EXPOSURE		STRICT HYGIENE!
•INHALATION	Cough. Sore throat.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Seek medical attention if you feel unwell .
•SKIN	Redness.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse skin with plenty of water or shower.
•EYES	Redness. Pain.	Safety goggles or eye protection in combination with breathing protection.	Rinse with plenty of water (remove contact lenses if easily possible). Refer for medical attention.
•INGESTION	Sore throat.	Do not eat, drink, or smoke during work.	Rinse mouth. Do NOT induce vomiting. Refer for medical attention if breathing difficulties and/or fever develop.

PHYSICAL STATE; APPEARANCE:
VERY VOLATILE COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. coholic order),18(benzene-like order), 20(ethereal order),24;

PHYSICAL DANGERS:
The vapour is heavier than air and may travel along the ground; distant ignition possible. As a result of flow, agitation, etc., electrostatic charges can be generated.

CHEMICAL DANGERS:
The substance may polymerize violently under the influence of base(s), acid(s) and metal chlorides with fire or explosion hazard. Reacts violently with chlorine, ammonia, strong oxidants and acids causing fire and explosion hazard. 35,43;

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA; A3 (confirmed animal carcinogen with unknown relevance to humans); SEN; (ACGIH 2009).
MAK: skin absorption (H);
Carcinogen category: 2;

OSHA PEL†: TWA 100 ppm (240 mg/m³)
NIOSH REL: Ca See Appendix A
NIOSH IDLH: Ca 400 ppm See: 75569

ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes , the skin and the respiratory tract . If swallowed the substance may cause vomiting, and could result in aspiration pneumonitis. of high concentrations may cause lung oedema (see Notes). rat oedema of pulmonary tissues 5000 mg/m³ 4h; oedema repeated exp; t high level could cause central nervous system depression. lack of data peer review;

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. This substance is possibly carcinogenic to humans. arc Cat 2),8(IARC 2B); ===> Carc (GHS Cat 2);
