![]() Remove: WHEN WET OR CONTAMINATED (LIQUID) - If this chemical is in liquid form, work clothing that becomes wet or significantly contaminated should be removed and replaced.Ĭhange: No recommendation is made specifying the need for the worker to change clothing after the workshift. Wash skin: WHEN CONTAMINATED (LIQUID) - If this chemical is in liquid form, the worker should immediately wash the skin when it becomes contaminated. Skin: PREVENT SKIN CONTACT (LIQUID) - If this chemical is in liquid form, wear appropriate personal protective clothing to prevent skin contact.Įyes: PREVENT EYE CONTACT (LIQUID) - If this chemical is in liquid form, wear appropriate eye protection to prevent eye contact. Įxcerpt from NIOSH Pocket Guide for Hydrogen fluoride : Contact with many silicon compounds and metal silicides causes violent evolution of gaseous silicon tetrafluoride. Emits highly corrosive fumes of hydrogen fluoride gas when heated. Reacts violently with arsenic trioxide, phosphorus pentachloride, acetic anhydride, alkali metals, ammonium hydroxide, chlorosulfonic acid, ethylenediamine, fluorine, potassium permanganate, oleum, propylene oxide, vinyl acetate, mercury(II) oxide. Reacts explosively with cyanogen fluoride, methanesulfonic acid or glycerol mixed with nitric acid. Can catalyze (increase the rate of) chemical reactions. ![]() Additional gas-generating reactions may occur with sulfites, nitrites, thiosulfates (to give H2S and SO3), dithionites (SO2), and carbonates. May generate flammable and/or toxic gases with dithiocarbamates, isocyanates, mercaptans, nitrides, nitriles, sulfides. ![]() Reacts with cyanide salts and compounds to release gaseous hydrogen cyanide. Can initiate polymerization in certain alkenes. Reacts exothermically with chemical bases (examples: amines, amides, inorganic hydroxides). May react with common metals (iron, steel) to generate flammable hydrogen gas if diluted below 65% with water. HYDROGEN FLUORIDE, ANHYDROUS attacks glass and any other silica containing material.
