5. FIRE-FIGHTING MEASURES<br />
Suitable extinguishing media<br />
Use water spray, alcohol-resistant foam, dry chemical or carbon dioxide.<br />
Special protective equipment for fire-fighters<br />
Wear self contained breathing apparatus for fire fighting if necessary.<br />
6. ACCIDENTAL RELEASE MEASURES<br />
Personal precautions<br />
Avoid dust formation.<br />
Environmental precautions<br />
Do not let product enter drains.<br />
Methods for cleaning up<br />
Sweep up and shovel. Keep in suitable, closed containers for disposal.<br />
7. HANDLING AND STORAGE<br />
Handling<br />
Provide appropriate exhaust ventilation at places where dust is formed. Normal measures for preventive fire<br />
protection.<br />
Storage<br />
Store in cool place. Keep container tightly closed in a dry and well-ventilated place.<br />
Keep wetted with water. Do not allow material to become dry.<br />
8. EXPOSURE CONTROLS/PERSONAL PROTECTION<br />
Personal protective equipment<br />
Respiratory protection<br />
Respiratory protection is not required. Where protection from nuisance levels of dusts are desired, use type<br />
N95 (US) or type P1 (EN 143) dust masks. Use respirators and components tested and approved under<br />
appropriate government standards such as NIOSH (US) or CEN (EU).<br />
Hand protection<br />
For prolonged or repeated contact use protective gloves.<br />
Eye protection<br />
Safety glasses<br />
Hygiene measures<br />
General industrial hygiene practice.<br />

10. STABILITY AND REACTIVITY<br />
Storage stability<br />
Stable under recommended storage conditions.<br />
Conditions to avoid<br />
Picric acid forms salts with many metals some of which are rather sensitive to heat, friction, or impact, e.g.,<br />
lead, iron, zinc, nickel, copper, etc., and should be considered dangerously sensitive. The salts formed with<br />
ammonia and amines, and the molecular complexes with aromatic hydrocarbons, etc, are in general not so<br />
sensitive. Contact of picric acid with concrete floors may form the friction-sensitive calcium salt. Dry mixtures of<br />
picric acid and aluminum powder are inert, but the addition of water causes ignition after a delay dependent<br />
upon the quantity added. Storage conditions: records of purchase dates should be maintained for each<br />
container. Material older than 2 years should be disposed. Inspect and add water every six months as needed.<br />
Rotate containers to distribute water every three months.<br />
Materials to avoid<br />
Strong bases, Reducing agents, Heavy metals, Heavy metal salts, Ammonia<br />
11. TOXICOLOGICAL INFORMATION<br />
Acute toxicity<br />
no data available<br />
Irritation and corrosion<br />
no data available<br />
Sensitisation<br />
no data available<br />
Chronic exposure<br />
IARC: No component of this product present at levels greater than or equal to 0.1% is identified as<br />
probable, possible or confirmed human carcinogen by IARC.<br />
Signs and Symptoms of Exposure<br />
Discoloration of the skin., Picric acid dust causes sensitization dermatitis. This usually occurs on the face,<br />
especially around the mouth and the sides of the nose; the condition progresses from edema, through the<br />
formation of papules and vesicles, to ultimate desquamation. Inhalation of high concentrations of dust has<br />
caused unconsciousness, weakness, muscle pain, and kidney problems. Swallowing picric acid may cause a<br />
bitter taste, headache, dizziness, nausea, vomiting, and diarrhea. High doses may cause destruction of the red<br />
blood cells and damage to the kidneys and liver with blood in the urine.<br />
Potential Health Effects<br />
Inhalation<br />
May be harmful if inhaled. May cause respiratory tract irritation.<br />
Skin<br />
May be harmful if absorbed through skin. May cause skin irritation.<br />
Eyes<br />
May cause eye irritation.<br />
Ingestion<br />
May be harmful if swallowed.<br />
