	ACUTE HAZARDS	PREVENTION	FIRE FIGHTING
FIRE & EXPLOSION	Combustible. Gives off irritating or toxic fumes (or gases) in a fire. Risk of fire and explosion.	NO open flames, NO sparks and NO smoking. Do NOT expose to friction or shock. Use non-sparking handtools. Prevent deposition of dust. Closed system, dust explosion-proof electrical equipment and lighting.	Use water in large amounts. In case of fire: keep drums, etc., cool by spraying with water. Combat fire from a sheltered position.

PREVENT DISPERSION OF DUST! STRICT HYGIENE!
	SYMPTOMS	PREVENTION	FIRST AID
Inhalation	See Ingestion.	Use local exhaust or breathing protection.	Fresh air, rest.
Skin	MAY BE ABSORBED! Redness. Roughness. Yellow staining of the skin. Further see Inhalation.	Protective gloves. Protective clothing.	Remove contaminated clothes. Rinse and then wash skin with water and soap. Refer immediately for medical attention .
Eyes	Yellow vision. Redness. Conjunctivitis.	Wear safety goggles.	First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Ingestion	Nausea. Sweating. Severe thirst. Fever. Increased heart rate. Vomiting. Shock or collapse.	Do not eat, drink, or smoke during work. Wash hands before eating.	Rest. Refer immediately for medical attention. See Notes.

ICSC: 0464

PHYSICAL & CHEMICAL INFORMATION
Physical State; Appearance CRYSTALS WITH CHARACTERISTIC ODOUR. Physical dangers Dust explosion possible if in powder or granular form, mixed with air. Chemical dangers May decompose explosively on shock, friction or concussion. May explode on heating. Mixtures with alkalis, ammonia and most metals are shock-sensitive. Decomposes on heating. This produces toxic gases including nitrogen oxides. See Notes.	Formula: C₆H₄N₂O₅ / C₆H₃(OH)(NO₂)₂ Molecular mass: 184.11 Melting point: 112°C Relative density (water = 1): 1.68 Solubility in water, g/l: 6 (poor) Relative vapour density (air = 1): 6.36 Octanol/water partition coefficient as log Pow: 1.67 (estimated)

EXPOSURE & HEALTH EFFECTS
Routes of exposure The substance can be absorbed into the body through the skin and by ingestion. Effects of short-term exposure The substance may be irritating to the eyes and skin.	Inhalation risk A nuisance-causing concentration of airborne particles can be reached quickly when dispersed. Effects of long-term or repeated exposure Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the metabolism. This may result in cataract, cardiovascular disorders and nervous system impairment.

EXPOSURE & HEALTH EFFECTS

Routes of exposure
The substance can be absorbed into the body through the skin and by ingestion.

Effects of short-term exposure
The substance may be irritating to the eyes and skin.

Inhalation risk
A nuisance-causing concentration of airborne particles can be reached quickly when dispersed.

Effects of long-term or repeated exposure
Repeated or prolonged contact with skin may cause dermatitis. The substance may have effects on the metabolism. This may result in cataract, cardiovascular disorders and nervous system impairment.

OCCUPATIONAL EXPOSURE LIMITS

ENVIRONMENT
The substance is very toxic to aquatic organisms. It is strongly advised not to let the chemical enter into the environment.

NOTES
Use all available methods for reducing body temperature. Because of its explosive properties, the compound is used in the form of a water paste. UN 0076 applies to the dry compound or wetted with less than 15% water (Hazard class 1, Subsidiary Risks 6.1). UN 1320 applies to compound wetted with no less than 15% water CAS 25550-58-7 applies to unspecified isomers of dinitrophenol.
