A great mask that leaks at the sides protects far less than people think. Make a clear, visual guide to fitting a respirator and the most common mistakes.
In a severe pandemic, good protective equipment used correctly could keep essential workers safe. The source list highlights fit-testing guides and better communication as open gaps.
Output: A printable one-page guide or infographic.
Read reputable guidance on respirator fit checks (look for occupational health or public health sources). Note the difference between a fit check and a fit test.
Beards, gaps at the nose, wrong size, loose straps, reusing damaged filters. Rank them by how often they likely happen.
Plan one page: three to five steps with simple drawings or photos, plus a “common mistakes” box.
Use any free design tool. Keep words short, text large and contrast high so it works when printed in black and white.
Hand it to a friend with a mask. Watch where they hesitate, then fix those parts.
All steps done
Share what you made, then try another project. The PDF version has room for notes.
Reusable respirators could protect essential workers in a severe pandemic. Many projects here are about evidence, communication and distribution.
The field lacks a friendly wiki. Pick one concept (far-UVC, DNA screening, elastomeric respirators, metagenomic surveillance) and write the clear, well-sourced page you wish existed.
When is it safe to publish something like “this mask might fail because…”? Review the infohazard literature and propose clearer guidance.
How many critical workers would a city need to protect? How much indoor space is there? What data would a government want on day one of a crisis?
