When this work cannot be done in the presence of water or other liquid, it shall be carried out by mechanical means, in covered air-tight apparatus.
If it is impossible to conform to the requirements of either of the first two paragraphs of this section, the work shall be done under a strong draught so arranged that the harmful products may be intercepted by apparatus suitably placed.
Finally, if none of these systems is possible the workmen shall be supplied with respirators.
4. Oxides and other compounds of lead, whether dry or damp, in suspension or solution, shall not be handled with the bare hand.

The same requirement applies to the floors of the workrooms, which shall also be kept damp.
