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. Risk of explosion on contact with many substances.
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
PREVENT DISPERSION OF DUST! AVOID ALL CONTACT! AVOID EXPOSURE OF (PREGNANT) WOMEN!

 •INHALATION Blue lips or finger nails. Blue skin. Headache. Dizziness. Nausea. Confusion. Convulsions. Unconsciousness.
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
 •SKIN MAY BE ABSORBED! (See Inhalation).
Protective gloves. Protective clothing.
Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer for medical attention.
 •EYES
Face shield.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
 •INGESTION (See Inhalation).
Do not eat, drink, or smoke during work. Wash hands before eating.
Rinse mouth. Give plenty of water to drink. Refer for medical attention.
SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING
Consult an expert! Personal protection: chemical protection suit including self-contained breathing apparatus. Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place.
Fireproof. Separated from strong bases,food and feedstuffsoxidants,strong reducing agents. Well closed. Keep in a well-ventilated room.
Do not transport with food and feedstuffs.

PHYSICAL STATE; APPEARANCE:
YELLOW , BROWN TO RED 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 and corrosive fumesincluding nitrogen oxides even in absence of air. Reacts with reducing agents , strong bases and oxidants causing explosion hazard.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.2 mg/m as TWA; (skin); A3 (confirmed animal carcinogen with unknown relevance to humans); BEI issued; (ACGIH 2004).
MAK: skin absorption (H);
Carcinogen category: 2;
(DFG 2004).
TLV and MAK are for mixed isomers (CAS 25321-14-6)


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, especially if powdered.

EFFECTS OF SHORT-TERM EXPOSURE:
The substance may cause effects on the blood , resulting in 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 formation of methaemoglobin. This substance is possibly carcinogenic to humans. Animal tests show that this substance possibly causes toxicity to human reproduction or development.

DATA

N O T E S
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. UN number for molten form: UN1600. See also ICSC0465 Dinitrotoluene (mixed isomers).
