TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Explosive. Many reactions may cause fire or explosion.
NO open flames, NO sparks, and NO smoking.
Water in large amounts. Do not attempt to extinguish large fire, evacuate area.
EXPLOSION Risk of fire and explosion upon rapid heating or strong shock.
Do NOT expose to friction or shock. Do not expose to heat and keep wet with at least 30% water.
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE
PREVENT DISPERSION OF DUST! STRICT HYGIENE!
IN ALL CASES CONSULT A DOCTOR!
Inhalation Headache. Blue lips or finger nails. Blue skin. Cough. Sore throat. Laboured breathing. Vomiting. Abdominal cramps. Unconsciousness. Symptoms may be delayed (see Notes).
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin MAY BE ABSORBED! Redness. Pain. Yellowish staining. (Further see Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention. Wear protective gloves when administering first aid.
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. Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Wear protective gloves when inducing vomiting.
SPILLAGE DISPOSAL PACKAGING & LABELLING

2,4,6-TRINITROTOLUENE ICSC: 0967
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
COLOURLESS TO YELLOW CRYSTALS

CHEMICAL DANGERS:
May explosively decompose on shock, friction, or concussion. Explodes on heating to 240C. Upon heating, toxic fumes are formed. Reacts violently with many chemicals (seek expert help) causing fire and explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m as TWA; (skin); (ACGIH 2004).
MAK: 0.11 ppm, 0.1 mg/m; Peak limitation category: II(2); skin absorption (H); Carcinogen category: 3B; Pregnancy risk group: IIc; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation of its aerosol, through the skin and by ingestion.

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

EFFECTS OF SHORT-TERM EXPOSURE:
The substance is irritating to the eyes, the skin and the respiratory tract. The substance may cause effects on the blood, resulting in hemolysis, formation of methaemoglobin. Exposure may result in death. The effects may be delayed (see Notes). Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the liver, blood and eyes, resulting in jaundice, anaemia, cataract.
PHYSICAL PROPERTIES
Boiling point (decomposes): 240C
Melting point: 80.1C
Density: 1.65 g/cm
Solubility in water, g/100 ml at 20C: 0.013
Vapour pressure, Pa at 20C: negligible
Relative vapour density (air = 1): 7.85
Octanol/water partition coefficient as log Pow: 1.60
ENVIRONMENTAL DATA
The substance is toxic to aquatic organisms. The substance may cause long-term effects in the aquatic environment. It is strongly advised not to let the chemical enter into the environment because it persists in the environment.
NOTES
Combustion in a confined space may turn into detonation. Depending on the degree of exposure, periodic medical examination is suggested. Specific treatment is necessary in case of poisoning with this substance; the appropriate means with instructions must be available. Do NOT take working clothes home.
Card has been partly updated in April 2005. See sections Occupational Exposure Limits, Emergency Response.
