Potential Health Effects
----------------------------------

Inhalation:
Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath. Systemic poisoning can cause headache, dizziness, nausea, vomiting, abdominal pain and diarrhea. Heavy exposures can cause red blood cell destruction resulting in bloody urine, liver and kidney damage, convulsions, weakness, muscle pain, coma and death.
Ingestion:
Causes irritation to the gastrointestinal tract. Symptoms may include nausea, vomiting and diarrhea. Other symptoms may parallel those from inhalation. Ingestion of 1 to 2 grams has caused severe poisoning.
Skin Contact:
Causes irritation to skin. Symptoms include redness, itching, and pain. May cause allergic skin reactions. May be absorbed through the skin with possible systemic effects.
Eye Contact:
Fume is irritating to the eyes. Splashes can cause eye injury.
Chronic Exposure:
Prolonged or repeated exposures can cause liver, kidney and blood effects. Hair and skin may become yellow (not jaundice). Conjunctiva of the eye may also become yellow with corresponding yellow vision.
Aggravation of Pre-existing Conditions:
Persons with pre-existing skin, blood, liver and kidney disorders may be more susceptible to the effects of this substance.

4. First Aid Measures

Inhalation:
Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical attention.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact:
Immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention. Wash clothing before reuse. Thoroughly clean shoes before reuse. Keep contaminated clothing wet after removing.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper eyelids occasionally. Get medical attention immediately.

5. Fire Fighting Measures

Fire:
Flash point: 150C (302F) CC
Autoignition temperature: 300C (572F)
Flammable Solid!
Dangerous fire hazard when exposed to heat or flame.
Explosion:
Dangerous explosion hazard when dry. Becomes increasingly shock, heat and friction sensitive as it loses its moisture. Explosive decomposition is likely if material is involved in a fire. Sealed containers may rupture when heated. Sensitive to mechanical impact. Sensitive to static discharge.
Fire Extinguishing Media:
Fight fire from protected location or maximum possible distance. Use flooding quantities of water as spray. DO NOT use carbon dioxide or halogenated extinguishing agents.
Special Information:
In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.

6. Accidental Release Measures

Remove all sources of ignition. Ventilate area of leak or spill. Keep unnecessary and unprotected people away from area of spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Clean-up personnel should be aware of material's explosive capabilities. Wet down spill and absorb with sodium bicarbonate or sand-soda ash mixture (90:10 mix). Carefully scoop into glass containers (make sure material has at least 10% water). Use non-metallic tools and non-sparking equipment. Do not flush to sewer. Large spills may need the attention of explosives experts. If handling picric acid contained in a jar, gently tilt bottle to see if crystals roll over each other. If they do, the acid is dry and capable of explosion--contact personnel trained in explosives. Dried crystals may also be present within threads of screw top containers and present a detonation hazard when opening container.


7. Handling and Storage

Protect against physical damage. Store in a cool, dry well-ventilated location, away from any area where the fire hazard may be acute. Outside or detached storage is preferred. Separate from incompatibles. Containers should be bonded and grounded for transfers to avoid static sparks. Storage and use areas should be No Smoking areas. Use non-sparking type tools and equipment, including explosion proof ventilation. Store in glass (not metal) containers and wet screw tops before sealing. Store in as small a quantity as possible and keep moist (at least 10% water--check periodically). Do not store on concrete floors (can form explosive calcium picrate). Enclose all processes and employ automatic-mechanical handling techniques and wet methods where possible. If handling picric acid contained in a jar, gently tilt bottle to see if crystals roll over each other. If they do, the acid is dry and capable of explosion--contact personnel trained in explosives. Dried crystals may also be present within threads of screw top containers and present a detonation hazard when opening container. Containers of this material are hazardous when empty since they retain product residues; observe all warnings for the product.

8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
OSHA Permissible Exposure Limit (PEL):
0.1 mg/m3 (TWA), skin
ACGIH Threshold Limit Value (TLV):
0.1 mg/m3 (TWA)
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details. Use explosion-proof equipment.
Personal Respirators (NIOSH Approved):
If the exposure limit is exceeded, a half-face dust/mist respirator may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece dust/mist respirator may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or a full face shield where splashing is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Other Control Measures:
Clothing contaminated with this material should be kept soaked with water and disposed of in the same manner as the material itself.
