PHENOLSULFONIC ACID is a strong acid. Reacts exothermically with chemical bases (for example: amines and inorganic hydroxides) to form salts. Dissolution in water or the dilution of a concentrated solutions with water may generate significant amounts of heat. Can serve as an oxidizing agent, but has a much weaker oxidizing action than sulfuric acid [Noller]. Can react with active metals, including iron and aluminum, and also many less active metals, to dissolve the metal and liberate hydrogen and/or toxic gases. Can initiate polymerization in certain classes of organic compounds. Reactions with cyanide salts and compounds release gaseous hydrogen cyanide. Flammable and/or toxic gases may be generated by reactions with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides, and strong reducing agents. Additional gas-generating reactions occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and even carbonates: the carbon dioxide gas from the last is nontoxic but the heat and spattering from the reaction can be troublesome. Can catalyze (increase the rate) of chemical reactions.

SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

If material not involved in fire: Keep material out of water sources and sewers. Build dikes to contain flow as necessary. Attempt to stop leak if without undue personnel hazard.

Personnel protection: Avoid breathing dusts or vapors. Avoid bodily contact with the material. Wear appropriate chemical protective gloves, boots, and goggles. Do not handle broken packages unless wearing appropriate personal protective equipment. Wash away any material which may have contacted the body with copious amounts of water or soap and water.
