TYPES OF HAZARD / EXPOSURE ACUTE HAZARDS / SYMPTOMS PREVENTION FIRST AID / FIRE FIGHTING
FIRE Combustible. Many reactions may cause fire or explosion. See Notes.
NO open flames.
Water in large amounts.
EXPLOSION Risk of fire and explosion.
Do NOT expose to friction or shock.
In case of fire: keep drums, etc., cool by spraying with water.
EXPOSURE
PREVENT DISPERSION OF DUST!

Inhalation Cough. Sore throat.
Local exhaust or breathing protection.
Fresh air, rest. Artificial respiration may be needed. Refer for medical attention.
Skin Redness. Yellow skin.
Protective gloves. Protective clothing.
Rinse and then wash skin with water and soap. Refer for medical attention.
Eyes Redness. Pain. Yellow vision.
Safety goggles.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor.
Ingestion Headache. Dizziness. Nausea. Vomiting. Diarrhoea.
Do not eat, drink, or smoke during work.
Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Refer for medical attention.
SPILLAGE DISPOSAL PACKAGING & LABELLING
Sweep spilled substance into containers; if appropriate, moisten first to prevent dusting. Carefully collect remainder, then remove to safe place. Personal protection: P3 filter respirator for toxic particles.

PICRIC ACID ICSC: 0316
IMPORTANT DATA
PHYSICAL STATE; APPEARANCE:
YELLOW CRYSTALS WITH NO ODOUR.

CHEMICAL DANGERS:
May explosively decompose on shock, friction, or concussion. May explode on heating. Shock-sensitive compounds are formed with metals, particularly copper, lead, mercury and zinc. On combustion, forms toxic carbon and nitrogen oxides. Reacts vigorously with oxidants and reducing materials.

OCCUPATIONAL EXPOSURE LIMITS:
TLV: 0.1 mg/m as TWA; (ACGIH 2004).
MAK: skin absorption (H); sensitization of skin (Sh); Carcinogen category: 3B; (DFG 2004).
ROUTES OF EXPOSURE:
The substance can be absorbed into the body by inhalation 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.

EFFECTS OF LONG-TERM OR REPEATED EXPOSURE:
Repeated or prolonged contact with skin may cause dermatitis. Skin and hair may be stained yellow.
PHYSICAL PROPERTIES
Melting point: 122C
Density: 1.8 g/cm
Solubility in water, g/100 ml: 1.4
Relative vapour density (air = 1): 7.9
Flash point: 150C
Auto-ignition temperature: 300C
Octanol/water partition coefficient as log Pow: 2.03
ENVIRONMENTAL DATA

NOTES
For safety transportation, 10-20% water is usually added. In normal conditions: combustible; if oxidized may become explosive. Do NOT take working clothes home. Rinse contaminated clothes (fire hazard) with plenty of water. Other UN number is 1344, with not less than 30% water by mass, hazard class 4.1, packing group I. Card has been partly updated in October 2005. See sections Occupational Exposure Limits, Emergency Response.
