As a ChemicalMan, the first and foremost aspect of dealing with any chemicals (or potential of exposure to chemicals) regardless of what they are is to handle them safely. The excerpt from the material safety data sheet shows the need for risk assessment even with minute quantities or residue. That assessment must be done by qualified people (i.e., chemical people.) SAFETY FIRST, debates later!
Which is why in the MSD you have this:
Personal protection
Safety glasses, gloves, good ventilation. Treat as a possible carcinogen. Remove all sources of ignition from the working area. Prepare a risk assessment before starting work.
