TYPES OF HAZARD/ EXPOSURE	ACUTE HAZARDS/ SYMPTOMS	PREVENTION	FIRST AID/ FIRE FIGHTING
FIRE	Explosive. Many reactions may cause fire or explosion. Gives off irritating or toxic fumes (or gases) in a fire.	NO open flames, NO sparks, and NO smoking. NO contact with hot surfaces.	Powder, water spray, foam, carbon dioxide.
EXPLOSION	Risk of fire and explosion.	Closed system, ventilation, explosion-proof electrical equipment and lighting. Use non-sparking handtools. Do NOT expose to friction or shock.	In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

EXPOSURE		STRICT HYGIENE!
•INHALATION	Abdominal cramps. Blue lips or finger nails. Blue skin. Dizziness. Headache. Laboured breathing. Nausea. Vomiting.	Ventilation, local exhaust, or breathing protection.	Fresh air, rest. Refer for medical attention.
•SKIN	MAY BE ABSORBED! (Further see Inhalation).	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
•EYES	Redness. Pain.	Face shield, 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	(Further see Inhalation).	Do not eat, drink, or smoke during work. Wash hands before eating.	Rinse mouth. Refer for medical attention.

PACKAGING & LABELLING

Evacuate danger area! Consult an expert! Shut off ignition sources. Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. (Extra personal protection: complete protective clothing including self-contained breathing apparatus).

Fireproof. Separated from food and feedstuffs. Well closed. Store only if stabilized.

Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW, VISCOUS LIQUID OR PALE YELLOW CRYSTALS.

PHYSICAL DANGERS:

CHEMICAL DANGERS:
Heating may cause violent combustion or explosion. May explosively decompose on shock, friction, or concussion. On combustion, forms toxic fumes including nitrogen oxides. Reacts with ozone causing explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.05 ppm; 0.46 mg/m³ TWA (skin) (ACGIH 1994-1995).
OSHA PEL: C 0.2 ppm (2 mg/m³) skin
NIOSH REL: ST 0.1 mg/m³ skin
NIOSH IDLH: 75 mg/m³

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

INHALATION RISK:
A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance irritates the eyes. The substance may cause effects on the cardiovascular system and blood , resulting in fall of blood pressure and circulatory collapse, and formation of methaemoglobin in larger amounts. Medical observation is indicated. See Notes.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact may cause skin sensitization. Repeated exposure leads to marked tolerance. Short absence from exposure may lead to sudden death.

PHYSICAL
PROPERTIES

Boiling point: explosion
Melting point: 13°C
Relative density (water = 1): 1.6
Solubility in water: poor

Vapour pressure, Pa at 20°C: 0.03
Relative vapour density (air = 1): 7.8
Auto-ignition temperature: 270°C

ENVIRONMENTAL
DATA

The substance is toxic to aquatic organisms.

N O T E S

Combustion in a confined space may turn into detonation. Use of alcoholic beverages enhances the harmful effect. Other UN numbers are: UN # 0144: nitroglycerin, solution in alcohol with more than 1% but not more than 10% nitroglycerin; UN Haz Class 1.1D. UN # 1204: nitroglycerin, solution in alcohol with not more than 1% of nitroglycerin; UN Haz Class 3, Pack Group II. UN # 3064: Nitroglycerin, solution in alcohol with more than 1% but not more than 5% of nitroglycerin, UN Haz Class 3, Pack Group II.
