Crush and impact hazard posed by components falling or toppling over accidentally.
When working with heavy components that have been removed or are yet to be installed,
injury may result if the components start moving in an uncontrolled manner, e.g., fall
down
from the working surface or topple over.
Place removed components exclusively on level, horizontal working surfaces with enough
load-bearing capacity.
If necessary, secure removed components so that they will not fall or topple over.
Wear the required personal protective equipment.
