Breathing powdered lead oxide is surely bad for everyone, especially
children.  (The eating of a lead paint chip the size of a fingernail
is enough to gravely affect a child's mental development.)

I don't know how much blows around a house during the normal operation
of an old player piano in which it hasn't been replaced with rubber,
but surely some does, and some is too much for me!

As with every aspect of preparing an old piano or player piano for
restoration (cleaning up, bellows cloth removal, etc.), I strongly
recommend removing the old lead tubing _outdoors_ while wearing an
appropriate mask (if possible, one made for use in lead paint removal)
and disposable gloves, with a good breeze, induced by a fan if need
be, blowing the various forms of century-old detritus _away_ from you!

Disposable paper suits from paint stores and departments are another
cheap and easy way to keep unseemly residues of The Past from defiling
Your Future, and, in lieu of them, an extra layer of clothing that can
be bagged for the washing machine prior to re-entering your house can
do much for "Domestic Tranquility".
