pH solutions.
Hazardous Properties/Exposure Symptoms
Corrosive. Severe burns. Fever, cough, dyspnea, cyanosis, pulmonary edema, blood spitting. Latency
period up to 2 days.
PPE - Personal Protective Equipment
Skin and eye protection. Wear impervious protective clothing. Neoprene, natural rubber, nitrile, Silver
Shield. LDPE storage bottle and Teflon carrying container that holds 3x the volume of the storage bottle
capable of fully containing a chemical spill. Avoid inhalation of fumes. Users will wear clean room
coverall garments, extra length chemical gloves and full face shield. All HNA activities must be carried

Always use in an exhausted acid cabinet. Always use in area equipped with an emergency shower and
eyewash.
Special Handling Procedures and Storage Requirements
Read MSDS prior to use. Containers should tightly closed and stored in a cool, dry, well ventilated area
away from incompatibles including glass, most metals, arsenic trioxide, calcium oxide, phosphorus
pentoxide, mercury oxide, nitric acid, sulfuric acid, sodium, sodium or potassium tetrafluorosilicate, nphenyl azopiperidine. Place storage bottle into the clean Teflon carrier at the designated area in the Clean
Room. Transport solution to third floor lab. Contact with water releases corrosive fumes. Do not store
with flammables. Place containers in trays to contain any accidental spills while in storage. Be mindful of
