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.

likely if material is involved in a fire.
Hazardous Decomposition Products:
Explosive decomposition is likely if material is involved in a fire.
Hazardous Polymerization:
