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.
Powder, water spray, foam, carbon dioxide .
EXPLOSION Finely dispersed particles form explosive mixtures in air.
Prevent deposition of dust; closed system, dust explosion-proof electrical equipment and lighting.
In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.
EXPOSURE
AVOID ALL CONTACT!

 •INHALATION Cough. Sore throat. Blue lips or finger nails.
Local exhaust or breathing protection.
Fresh air, rest. Refer for medical attention.
 •SKIN MAY BE ABSORBED! Redness. Pain.
Protective clothing. Protective gloves.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
 •EYES Redness. Pain.
Safety goggles .
Rinse with plenty of water (remove contact lenses if easily possible).
 •INGESTION Blue lips or fingernails. Blue skin. Dizziness. Headache. Nausea. Confusion. Convulsions. Unconsciousness.
Do not eat, drink, or smoke during work.
Rinse mouth. Give a slurry of activated charcoal in water to drink. Refer for medical attention.

PHYSICAL STATE; APPEARANCE:
YELLOWTO ORANGE-YELLOW CRYSTALS , WITH CHARACTERISTIC ODOUR.

PHYSICAL DANGERS:
Dust explosion possible if in powder or granular form, mixed with air.

CHEMICAL DANGERS:
May explode on heating. The substance decomposes on heating producing toxic fumes , including nitrogen oxides even in absence of air (see ICSC 0727). Reacts with strong oxidants. Reacts with reducing agents , strong bases , amines , zinc , and tin.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: as mixture 0.2 mg/m as TWA (skin) A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued (ACGIH 2004).
MAK not established.
skin absorption (H);
Carcinogen category: 2
(DFG 2004).


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

INHALATION RISK:
A harmful concentration of airborne particles can be reached quickly when dispersed.

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 the formation of methaemoglobin. The effects may be delayed. Medical observation is indicated.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
The substance may have effects on the blood , resulting in the formation of methaemoglobin. This substance is possibly carcinogenic to humans.

ENVIRONMENTAL
DATA
Environmental Hazard placard The substance is toxic to aquatic organisms. It is strongly advised that this substance does not enter the environment.
N O T E S
Combustion in a confined space may turn into detonation. 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. See also ICSC0726 2,3-Dinitrotoluene; 0727 2,4-Dinitritoluene; 0728 2,6-Dinitrotoluene; 0729 3,4-Dinitrotoluene.
