The CDC has guidelines on building a 'drum' incinerator in their
'Viral Haemorrhagic Fevers' Manual - this manual is designed for use
in Low-Tech situations as might be found in a Third-World setting, or
more specifically, in remote African locales threatened by Ebola.

The above webpage has specific chapters and annexes/appendices of the
manual available as separate HTML and PDF downloads, or you can
download the lot in one go as a PDF document.

Chapter you want is 'Annex 10', down the bottom of the page - the
above webpage states 'Annex 9', but the pictures are in the 'Community
Information Posters' section in the Annex 10 webpage.

This page has the step by step pictorial instructions.

I think ALL survival-minded people should print this CDC document out,
as it contains a LOT of good 'Do-It-Yourself' info - including how to
make your own hospital masks and gowns.
