When climbing up a ladder, it doesn't
matter how dirty
are your shoes, because as you ascend,
each rung
presents itself as a clean hand hold.
Going down is a
different matter, as you will now
encounter the rungs
where your shoes have been, leaving all
manner of
nefarious matter.
Climb
Down With a Clean Pair of Hands
solves this
problem. It does this by a simple
variation on the
standard ladder. This takes the form of
two additional
vertical supports which run from top to
bottom;
adjacent to, and parallel to the main
supports.
The two extra supports create spaces up
both sides of
the ladder which are too small to permit
the insertion
of a foot, but the perfect size for each
hand. Being
made of light material, because they
have no structural
function, they do not add significantly to
the overall
weight of the ladder.

I take it that holding the sides of the ladder is not an option? |
|

I have been told that ladder safety protocol calls for only moving one foot or one hand at a time. I would think that using the rungs for a handgrip would be safer than gripping the sides. |

Granted, I learned this as a child watching an adult climb down a decaying wooden ladder into an old mineshaft. |

What you need is the "Disposable Roofmat" |
|
| |
For removal of nefarious matter from the feet - which can only come from the roof - before the descent. You did scrape your feet on the bottom rung on the way up, didn't you? |

Tradesmen never wipe their feet. Their union forbids it. |
