Projects
Safety (assemblies)
faceplanting
Hazard: not cane detectable (too high)
lowest, nearest edge higher than knee & lower than top of head
e.g. signs, spheres, phone booths, guy lines, branches, underside of stairs
Fix: make it detectable and/or blocked
put something solid under it at floor level to prevent walking into faceplant zone
e.g. backpacks, speakers, large cable cover
Please no backpacks etc. This is a fire safety hazard.
Maybe put special textured tape on floor? [Pixtxa]
yes! or bumps like cable covers - Sai
Exceptions: light, smooth-edged furniture (e.g. tables, chairs) that won't hurt to run into
tripping & shin bruises
Hazard: not cane detectable (too small or movable)
cane might pass over it
e.g. cables smaller than ultra-thick power cables, bollards lower than elbow height, small robots / toddlers, small bags in walking area
Fix: make it detectable, safe/padded, or gone
e.g. cable covers; padding around short bollards; child care services; sound generator on robots; clean up trash; stow bags on tables or along the wall; tactile paving indicator for upcoming hazard (eg stairs up)
falling
Hazard: walking surface drops (ledge or very steep slope)
e.g. stairs down, edge of platform/stage
Fix: hazard warning or barrier
e.g. tactile paving (bumps or horizontal lines); cable covers with prominent texture (like crosshatch); tape with very prominent texture (strands, bumps, etc)
for stairs, mark both start and end
