TYPES OF HAZARD / EXPOSURE	ACUTE HAZARDS / SYMPTOMS	PREVENTION	FIRST AID / FIRE FIGHTING
FIRE	Combustible. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames.	Foam, dry powder, carbon dioxide.
EXPLOSION	Above 56°C explosive vapour/air mixtures may be formed.	Above 56°C use a closed system, ventilation.

EXPOSURE
Inhalation	Burning sensation. Cough. Chest tightness. Nausea. Vomiting.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest.
Skin	Burning sensation. Redness.	Protective gloves.	Remove contaminated clothes. Rinse and then wash skin with water and soap.
Eyes	Redness. Pain. Causes watering of the eyes.	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		Do not eat, drink, or smoke during work.

ALLYL PROPYL DISULFIDE

ICSC: 1422

IMPORTANT DATA

PHYSICAL STATE; APPEARANCE:
PALE YELLOW LIQUID, WITH PUNGENT ODOUR.

CHEMICAL DANGERS:
The substance decomposes on burning producing sulfur oxides. Reacts with oxidants.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 2 ppm as TWA, 3 ppm as STEL; Intended change: 0.5 ppm SEN; (ACGIH 2004).
MAK: 2 ppm, 12 mg/mł Peak limitation category: I(1); (DFG 2004).

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

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 irritating to the eyes, the skin and the respiratory tract
