OSHA Hazards: Flammable solid, Target Organ Effect, Toxic by inhalation., Toxic by ingestion, Toxic by skin absorption, Skin sensitizer
Target Organs: Liver, Kidney, Blood

Risk of explosion by shock, friction, fire or other sources of ignition. Extreme risk of explosion by shock, fire, friction or other sources of ignition. Forms very sensitive explosive metallic compounds.


Toxic by inhalation, in contact with skin and if swallowed.
Highly flammable.



SWALLOWED: Toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 40 gram may be fatal or may produce serious damage to the health of the individual.
Picric acid has an intense bitter taste. Several human poisonings have occurred after the ingestion of 1-2 grams picric acid. Symptoms include gastroenteritis, toxic hepatitis, inflammation of the kidney (nephritis), blood in the urine (haematuria) and other urinary symptoms.
Skin and conjunctiva become yellow due to acidosis and jaundice.
Death may follow renal lesions and anuria (both major kidney dysfunctions). Rarely, jaundice and coma with convulsions proceed death.
The  substance  and/or  its  metabolites  may  bind  to  hemoglobin inhibiting  normal  uptake  of  oxygen.  This  condition,  known  as "methemoglobinemia", is a form of oxygen starvation (anoxia).
Symptoms include cyanosis (a bluish discoloration skin and mucous membranes) and breathing difficulties. Symptoms may not be evident until several hours after exposure.
At about 15% concentration of blood methemoglobin there is observable cyanosis of the lips, nose and earlobes. Symptoms may be absent although euphoria, flushed face and headache are commonly experienced. At 25-40%, cyanosis is marked but little disability occurs other than  that  produced  on  physical  exertion.  At  40-60%,  symptoms  include  weakness,  dizziness,  lightheadedness,  increasingly  severe headache, ataxia, rapid shallow respiration, drowsiness, nausea, vomiting, confusion, lethargy and stupor. Above 60% symptoms include dyspnea, respiratory depression, tachycardia or bradycardia, and convulsions. Levels exceeding 70% may be fatal.

EYE: Although the material is not thought to be an irritant, direct contact with the eye may produce transient discomfort characterized by tearing or conjunctival redness (as with windburn). Strange yellow vision is symptomatic of over-exposure, to picric acid, by this or other routes. Buffered solutions of picric acid produce lesions of significant severity in the range pH 1.5 to pH 9 with little significant difference.
SKIN: Skin contact with the material may produce toxic effects; systemic effects may result following absorption. The material is not thought to be a skin irritant (as classified using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting. Skin absorption of picric acid may cause headache, vertigo with nausea, vomiting and rashes. Hair may be discolored yellow. Topical application may result in local or generalized allergic reaction. Open cuts, abraded or irritated skin should not be exposed to this material. Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.

INHALED: Inhalation of vapors or aerosols (mists, fumes), generated by the material during the course of normal handling, may produce toxic effects. The material is not thought to produce respiratory irritation (as classified using animal models). Nevertheless inhalation of the material, especially for prolonged periods, may produce respiratory discomfort and occasionally, distress. Inhalation of high dust concentrations of picric acid may result in temporary unconsciousness followed by weakness, muscle pain, failure to produce urine (anuria) and later, excess urine production (polyuria).


Limited evidence suggests that repeated or long-term occupational exposure may produce cumulative health effects involving organs or biochemical systems. There is limited evidence that, skin contact with this product is more likely to cause a sensitization reaction in some persons compared to the general population. Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities.

Always seek medical attention after first aid measures are provided.

Where Medical attention is not immediately available or where the patient is more than 15 minutes from a hospital or unless instructed otherwise:
For advice, contact a Poisons Information Center or a doctor.
Urgent hospital treatment is likely to be needed.
If conscious, give water to drink.
INDUCE vomiting with fingers down the back of the throat, ONLY IF CONSCIOUS. Lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration.
NOTE: Wear a protective glove when inducing vomiting by mechanical means. In the mean time, qualified first-aid personnel should treat the patient following observation and employing supportive measures as indicated by the patient's condition. If the services of a medical officer or medical doctor are readily available, the patient should be placed in his/her care and a copy of the MSDS should be provided. Further action will be the responsibility of the medical specialist. If medical attention is not available on the worksite or surroundings send the patient to a hospital together with a copy of the MSDS.

If this product comes in contact with the eyes, immediately hold eyelids apart and flush the eye continuously with running water. Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids. Continue flushing until advised to stop by the Poisons Information Center or a doctor, or for at least 15 minutes. Transport to hospital or doctor without delay. Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.

If skin or hair contact occurs, quickly but gently, wipe material off skin with a dry, clean cloth. Immediately remove all contaminated clothing, including footwear. Wash skin and hair with running water. Continue flushing with water until advised to stop by the Poisons Information Center. Transport to hospital, or doctor.

If fumes or combustion products are inhaled remove from contaminated area. Lay patient down. Keep warm and rested. Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures. Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary. Transport to hospital, or doctor, without delay.

Symptoms of vasodilation and reflex tachycardia may present following organic nitrate overdose; most organic nitrates are extensively metabolized by hydrolysis to inorganic nitrites. Organic nitrates and nitrites are readily absorbed through the skin, lungs, mucosa and gastrointestinal tract.
The toxicity of nitrates and nitrites result from their vasodilating properties and their propensity to form methemoglobin.
Most produce a peak effect within 30 minutes.
Clinical signs of cyanosis appear before other symptoms because of the dark pigmentation of methemoglobin.
Initial attention should be directed towards improving oxygen delivery, with assisted ventilation, if necessary. Hyperbaric oxygen has not demonstrated conclusive benefits.
Institute cardiac monitoring, especially in patients with coronary artery or pulmonary disease.
Hypotension should respond to Trendelenburg's position and intravenous fluids; otherwise dopamine may be needed.
Naloxone, glucose and thiamine should be given if a multiple ingestion is suspected.
Decontaminate using Ipecac Syrup for alert patients or lavage for obtunded patients who present within 2-4 hours of ingestion.
Symptomatic patients with methemoglobin levels over 30% should receive methylene blue. (Cyanosis alone, is not an indication for treatment). The usual dose is 1-2 mg/kg of a 1% solution (10 mg/ml) IV over 5 minutes; repeat, using the same dose if symptoms of hypoxia fail to subside within 1 hour.

The TLV-TWA is thought to be protective against the development of systemic toxicity but may not, however, prevent the development of dermatitis or sensitization in some workers exposed at the 8-hour TWA.

Consult your EHS staff for recommendations

Safety glasses with side shields.
Chemical goggles.
Contact lenses pose a special hazard; soft lenses may absorb irritants and all lenses concentrate them. DO NOT wear contact lenses.

NOTE: The material may produce skin sensitization in predisposed individuals. Care must be taken, when removing gloves and other protective equipment, to avoid all possible skin contact.
Neoprene gloves
Wear physical protective gloves, e.g.. leather.
Wear safety footwear.

Eyewash unit.
Barrier cream.
Skin cleansing cream.
Some plastic personal protective equipment (PPE) (e.g. gloves, aprons, overshoes) are not recommended as they may produce static electricity.
For large scale or continuous use wear tight-weave non-static clothing (no metallic fasteners, cuffs or pockets), non sparking safety footwear.
Respirators may be necessary when engineering and administrative controls do not adequately prevent exposures.
The decision to use respiratory protection should be based on professional judgment that takes into account toxicity information, exposure measurement data, and frequency and likelihood of the worker's exposure - ensure users are not subject to high thermal loads which may result in heat stress or distress due to personal protective equipment (powered, positive flow, full face apparatus may be an option).
Use approved positive flow mask if significant quantities of dust becomes airborne.
Try to avoid creating dust conditions.
Use appropriate NIOSH-certified respirator based on informed professional judgment. In conditions where no reasonable estimate of exposure can be made, assume the exposure is in a concentration IDLH and use NIOSH-certified full face pressure demand SCBA with a minimum service life of 30 minutes, or a combination full face piece pressure demand SAR with auxiliary self-contained air supply. Respirators provided only for escape from IDLH atmospheres shall be NIOSH-certified for escape from the atmosphere in which they will be used.

Local exhaust ventilation usually required. If risk of overexposure exists, wear an approved respirator. Correct fit is essential to obtain adequate protection an approved self contained breathing apparatus (SCBA) may be required in some situations. Provide adequate ventilation in warehouse or closed storage area.
Air contaminants generated in the workplace possess varying "escape" velocities which, in turn, determine the "capture velocities" of fresh circulating air required to effectively remove the contaminant.
For large scale or continuous use:
Spark-free, earthed ventilation system, venting directly to the outside and separate from usual ventilation systems Provide dust collectors with explosion vents

Picric acid when dry is a highly unstable and heat, friction-, and impact- sensitive explosive (explodes at approximately 300 C) explosive sensitivity increases when trace metals are present reacts with nitric acid, alkalis, heavy metals, copper, lead, zinc, transition metals, and other metals and their salts, to form other salts known as picrates; these are initiators which are much more highly sensitive to heat, impact, or shock than the parent compound shock sensitive salts include ammonium salts and calcium salts (the calcium salt may be produced when picric acid comes in contact with plaster or concrete - do NOT store on uncoated concrete) mixtures with perchlorates form extremely powerful, high velocity explosives reacts violently with strong oxidizers is incompatible with ammonia may accumulate static electric charge, when dry, producing explosion is a strong oxidizer in aqueous solution and a strong acid reacts violently with alkalis, reducing agents, combustible materials, organic materials and other easily oxidized materials, aluminium powders, and other metal powders attacks many materials, forming flammable hydrogen gas attacks natural rubber, polyvinyl alcohol, PVC, Polynitro derivatives of mono- and poly- cyclic systems are often explosives liable to detonate on grinding or impact. The presence of two or more nitro groups (each with 2 oxygen atoms) on an aromatic nucleus often increase the reactivity of other substituents and the tendency towards explosive instability as oxygen balance is approached. Aromatic nitro compounds range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.

In view of the reports of previous violent or explosive reactions, heating of polynitroaryl (particularly di- and tri-nitroaryl) compounds with alkalies, ammonia, or O-ethylsulfuric acid salts, in autoclaves should be avoided.

Nitroaromatic and in particular polynitroaromatic compounds may present a severe explosion risk if subjected to shock or heated rapidly and uncontrollably as in fire situations. In addition, when such compounds are heated more moderately with caustic alkalies, even when water or organic solvents are present, there is also a risk of violent decomposition or explosion. Several industrial accidents, which probably were due to such interactions, have occurred; this potential hazard often remains unacknowledged.

A range of exothermic decomposition energies for nitro compounds is given as 220-410 kJ/mol. The relationship between energy of decomposition and processing hazards has been the subject of discussion; it is suggested that values of energy released per unit of mass, rather than on a molar basis (J/g) be used in the assessment. For example, in "open vessel processes" (with man-hole size openings, in an industrial setting), substances with exothermic decomposition energies below 500 J/g are unlikely to present a danger, whilst those in "closed vessel processes" (opening is a safety valve or bursting disk) present some danger where the decomposition energy exceeds 150 J/g.

Avoid reaction with oxidizing agents, bases and strong reducing agents.

Harmful to aquatic organisms.

The nitrates are of environmental concern because of their high water solubility and consequent leaching, diffusion, and environmental mobility in soil and water. Nitrate can contaminate groundwater to unacceptable levels. Nitrite is formed from nitrate or ammonium ion by micro-organisms in soil, water, sewage and the alimentary tract. The concern with nitrate in the environment is related to its conversion to nitrite. Methemoglobinemia is caused following exposure to high levels of nitrite and produces difficulties in oxygen transport in the blood. Thousands of cases involving poisoning of infants, particularly in rural areas, have been reported as a result of drinking nitrate rich well-water. Other concerns deriving from exposure to environmental nitrates relate to the production of nitrosamines following the reaction of food nitrites and secondary amines. Other nitroso-compounds may result following reaction with nitrites and amides, ureas, carbamates and other nitrogenous compounds. Nitrosamines produce liver damage, hemorrhagic lung lesions, convulsions and coma in rats, and teratogenic effects in experimental animals.

The N-nitroso class of compounds include potent carcinogens and mutagens: induction of tumors by single doses of N-nitroso compounds testify to this.

DO NOT discharge into sewer or waterways.

US EPA Waste Number & Descriptions

A. General Product Information
Ignitability characteristic: use EPA hazardous waste number D001 (waste code I)

Disposal Instructions:
All waste must be handled in accordance with local, state and federal regulations.
# Puncture containers to prevent re-use and bury at an authorized landfill.
Explosives which are surplus, deteriorated or considered unsafe for transport, storage or use shall be destroyed and the statutory authorities shall be notified.
Explosives must not be thrown away, buried, discarded or placed with garbage.
This material may be disposed of by burning or detonation but the operation must be performed under the control of a person competent in the destruction of explosives.

Disposal by detonation:
The explosives to be destroyed must be placed in direct contact with fresh priming charge in a hole which is at least 0.6 meter deep and then adequately stemmed.
No detonators shall be inserted into defective explosives.
Personnel must be evacuated to a safe distance prior to initiation/firing of the charge. Disposal by burning:
Make a sawdust bed or trail adequate for the quantity of explosives to be burned, approximately 400mm wide and 40 mm deep, upon which the explosive will be laid.
If sawdust is not available, newspaper may be used.
Normal precautions shall be taken to avoid the spread of fire.
Individual trails should not be closer together than 600 mm and should contain not more than 12 Kg of explosive.
Trails should be side by side, NOT in-line, and not more than four should be set up at one time.
Remove any explosive that is not to be burnt to a distance of at least 300 meter.
Sufficient diesel oil (never petrol or other highly inflammable liquid) should be used to thoroughly wet the sawdust (or paper) at least 4L per trail is recommended.
Light the trail from a long, rolled paper wick which should be placed downwind and in contact with the end 1m of trail that is not covered with explosive. The wind should blow so that the flame from the wick (and later from the burning explosive) will blow away from the unburned explosive as detonation is more likely to occur if the explosive is preheated by the flame.
If plastic igniter cord (slow) is available, its use for lighting is recommended instead of paper. One end should be coiled into the sawdust or under the paper and the other end lit from a minimum distance of 7m from the trail.
Retire at least 300m or to a safe place.
DO NOT return to the site for at least 30 minutes after the burning has apparently finished.
If the fire goes out do not approach for at least 15 minutes after all trace of fire has gone.
DO NOT add more diesel oil unless certain that the flame is completely extinguished.
