To minimize exposure to toxic substances by any route using all reasonable precautions. These precautions are appropriate for substances with moderate chronic or high acute toxicity used in significant quantities.
Hydrofluoric acid is more hazardous than other acids due to how seriously it can burn.
Hydrofluoric acid releases fluoride ions into deep tissue layers causing severe burns which are not easily apparent. Medical personnel can misdiagnose HF burns and treat for hydrochloric acid burns. Material Safety Data Sheets and notification of use must be sent to the KRC Safety Specialist. Lab work with these substances can only be done in the CNTech Process cleanroom, the SRC Chemical Room or other laboratory equipped with a fumehood. Always use a fumehood, previously evaluated to confirm adequate performance with a face velocity of at least 100 linear feet per minute, or other containment device for procedures which may result in the generation of aerosols or vapors containing the substance.
