Fresh air, rest. Seek medical attention if you feel unwell.
Remove contaminated clothes. Rinse skin with plenty of water or shower.
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
Rinse mouth. Refer for medical attention .
Inhalation of dust causes irritation of nose and throat. Ingestion may cause severe gastrointestinal irritation, convulsions, circulatory collapse, and death. Contact with eyes causes irritation. Skin contact can cause local discoloration, irritation, eczema, and death; repeated contact can cause sensitization. (USCG, 1999)
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. Phenols and related compounds

The substance is irritating to the eyes and respiratory tract. The substance is mildly irritating to the skin.
Repeated or prolonged contact may cause skin sensitization.
Evaporation at 20°C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
AEROBIC: An aerobic biodegradation study of pyrogallic acid at an initial concentration of 500 ppm, based on BOD measurements, and using an activated sludge inoculum of 5230, 3310, and 6640 ppm, indicated 24, 16, and 23% theoretical BOD, respectively, over a period of 0.5 days(1). An aerobic biodegradation study of pyrogallic acid, based on BOD measurements, using a sewage inoculum at 20 deg C and an unknown pyrogallic acid initial concentration, indicated 2% BODT, over a period of 5 days(2). An aerobic biodegradation study of pyrogallic acid, based on COD measurements, using an activated sludge inoculum of 100 mg/L and an initial pyrogallic acid concentration of 200 ppm, indicated 40% COD removal over a period of 5 days at pH 7.2 and 20 deg C(3). An aerobic biodegradation study of pyrogallic acid, based on COD measurements, using an activated sludge inoculum and an initial pyrogallic acid concentration of 200 ppm, indicated 0, 23, 35, 45, 57, 70, 70, 70, and 69 percent COD removal after 0, 2.5, 5, 10, 20, 30, 40, 50, 60, 63 days, respectively(4).
An estimated BCF of 3.2 was calculated for pyrogallic acid(SRC), using an estimated log Kow of 0.97(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low(SRC).
Using a structure estimation method based on molecular connectivity indices(1), the Koc of pyrogallic acid can be estimated to be 320(SRC). According to a classification scheme(2), this estimated Koc value suggests that pyrogallic acid is expected to have moderate mobility in soil. The pKa of pyrogallic acid is 9.01(3), indicating that this compound will partially exist in the anion form in the environment and anions do not adsorb more strongly to soils containing organic carbon and clay than their neutral counterparts(4).

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.
