- Is known or found to be corrosive to living tissue.
- Handle corrosive chemicals with all proper safety precautions,
including wearing both safety goggles and a face shield,
gloves tested for the absence of pin holes and known to be resistant
to permeation or penetration by corrosives, a laboratory coat and a rubberized
