10 Standard applicability
The OSHA standard requires construction employers to: identify and evaluate fall hazards provide fall protection train employees The requirements are performance-oriented 3a

11 Standard applicability
The standard does not cover construction workers who are inspecting, investigating, or assessing workplace conditions: prior to the actual start of work; or after all work has been completed 3b

12 Standard applicability
Other OSHA standards also contain fall protection requirements, but they may not outline specific rules for fall protection during all parts of the job 3c
