Immediate first aid: Ensure that adequate decontamination has been carried out. If patient is not breathing, start artificial respiration, preferably with a demand-valve resuscitator, bag-valve-mask device, or pocket mask, as trained. Perform CPR as necessary. Immediately flush contaminated eyes with gently flowing water. Do not induce vomiting. If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain an open airway and prevent aspiration. Keep patient quiet and maintain normal body temperature. Obtain medical attention. Dinitrophenol and Related Compounds

This chemical is a flammable solid. Use flooding quantities of water, applied from a distance More powerful than TNT, picric acid explodes above 572 deg F (300 deg C). Use dry chemical, carbon dioxide, water spray, or alcohol foam extinguishers ... If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Notify local health and fire officials and pollution control agencies. Containers may explode. From a secure, explosion-proof location, use water spray to cool exposed containers. If cooling streams are ineffective (venting sound increases in volume and pitch, tank discolors or shows any signs of deforming), withdraw immediately to a secure position ... The only respirators recommended for fire fighting are self-contained breathing apparatuses that have full facepieces and are operated in a pressure-demand or other positive-pressure mode.

May decompose on shock, friction or concussion. May explode on heating. Mixtures with copper, lead, mercury, zinc and other metals are shock-sensitive. On combustion, forms toxic carbon and nitrogen oxides. Reacts with oxidants and reducing agents.

Very unstable.

Flammable solid.As a result of flow, agitation, etc., electrostatic charges can be generated. Dust explosion possible if in powder or granular form, mixed with air.PICRIC ACID, [DRY] undergoes vigorous reactions with both oxidizing or reducing agents. Apt to explode when shocked or exposed to heat. Very unstable. Readily forms salts on contact with many metals (including copper, lead, mercury, zinc, nickel, iron) that are more sensitive explosives than picric acid itself when subjected to heat, friction, or impact. Contact with concrete floors may form the friction-sensitive calcium picrate [Urbanski, 1964, vol. 1, p. 518]. Contact with metallic zinc or lead can cause detonation. Salts with ammonia, amines and complexes with hydrocarbons are less sensitive [Kirk-Othmer, 1965, vol. 8, p. 617]. Sufficiently pure samples of picric acid have the same order of stability as TNT [Chem. Eng. News, 1979, 57(41), p. 51]. Impure samples are less stable. Mixtures with aluminum and water will ignite after a delay period [Hajek, V. et al., Research, 1951, 4, p. 186].

The substance is mildly irritating to the eyes.

Repeated or prolonged contact with skin may cause dermatitis. Ingestion may cause effects on the gastrointestinal tract, kidneys, liver and blood.

Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.

AEROBIC: Mixed cultures of phenol adapted microorganisms exhibited little or no oxygen uptake in the presence of picric acid(2,3), suggesting that picric acid is resistant to degradation under aerobic conditions. It is reported that nitrophenols can inhibit aerobic microbial growth by uncoupling the metabolic process of oxidative phosphorylation(1). Based upon information pertaining to 2,4-dinitrophenol, possible biotransformation processes of picric acid are: reduction of the nitro group, hydroxylation of the aromatic ring, and displacement of the nitro group by a hydroxyl group(4). Picric acid, present at 100 mg/L, reached 23% of its Theoretical BOD in 4 weeks using an activated sludge inoculum at 30 mg/L in the Japanese MITI test(5).

BCF values of <0.24 and <2.2 were measured in carp (Cyprinus carpio) exposed to 500 ug/L and 50 ug/L of picric acid, respectively, over a 6 week exposure period(1). According to a classification scheme(2), these BCF values suggest that bioconcentration in aquatic organisms is low(SRC).

The Koc of picric acid is estimated as 180(SRC), using a log Kow of 1.44(1) and a regression-derived equation(2). According to a classification scheme(3), this estimated Koc value suggests that picric acid is expected to have moderate mobility in soil. The pKa of picric acid is 0.42(4), indicating that this compound will almost entirely exist in anion form in the environment and anions generally do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(5).

The material can be disposed of by removal to a licensed chemical destruction plant or by controlled incineration with flue gas scrubbing. Do not contaminate water, foodstuffs, feed or seed by storage or disposal. Do not discharge to sewer systems.

Containers can be triply rinsed (or equivalent) and offered for recycling or reconditioning. Alternatively, the packaging can be punctured to make it unusable for other purposes and then be disposed of in a sanitary landfill. Controlled incineration with flue gas scrubbing is possible for combustible packaging materials.
