The most general type of falls involving buildings are "falls from roof". Another category, usually for new construction sites, is "falls from roof structural member".
Falls from roof can be from "unprotected" walking surface, that is, no guard rail or no parapet wall of proper height. This is quite common, and can be easily avoided.
There is another particular classification of falls, the "falls thru roof", as follows:
- roof opening
- sky lights
- non-supportive materials (old, weak, deteriorated)
Many falls are caused simply due to carelessness or lack of fall prevention equipment. Most fall injuries can be avoided or minimized via the use of fall protection equipment.
