Acid

Stability:	Incompatibilities:	Hazardous Decomposition Products:	Conditions to Avoid:
Stable under ordinary conditions of use and storage.	Fluoboric Acid is incompatible with alkalis, acetic anhydride, heaxafluoroisopropylidene amino lithium, metals (forms flammable hydrogen gas).	Hydrogen fluoride and boron may be released when heated to decomposition.	Exposure to metals and other incompatibles.

Personal Respirators (NIOSH Approved): If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece respirator with an acid gas cartridge and particulate filter (NIOSH type N100 filter) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P particulate filter.

Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in section 8. Isolate hazard area. Keep unnecessary and unprotected personnel from entering. Contain and recover liquid when possible. Neutralize with alkaline material (soda ash, lime), then absorb with an inert material (e. G. , vermiculite, dry sand, earth), and place in a chemical waste container. Do not use combustible materials, such as saw dust. Do not flush to sewer!
