The total costs of fatal and nonfatal injuries in the construction industry were estimated at $11.5 billion in 2002, 15% of the costs for all private industry. The average cost per case of fatal or nonfatal injury is $27,000 in construction, almost double the per-case cost of $15,000 for all industry in 2002.

- New construction
- Behind schedule and over budget
- Injuries have plagued the worksite
- A foreman is on the top step of a 14' stepladder screwing in a light bulb 20' above the ground
- The foreman is in charge of a key group of workers and is vital for the completion of the project.
- The foreman is a hothead and has consistently given you problems, but does good work, and his journeymen and apprentices are loyal to him.
- All his workers are overworked and stressed. They are busy doing their work, so he is forced to use leftover supplies (i.e. the ladder) to do this simple task unsafely.
Ladder is placed incorrectly. Ladder should be extended out with its spreaders locked. If the work area is too small, an alternative should be used.

Unsafe posture. Worker should be facing the ladder and on a lower rung. A taller ladder facing the opposite direction may be necessary.

Unsafe posture. Worker should be on a lower rung; a taller ladder is needed.

Extension ladder should extend past the roof by at least three feet. Worker is in an unsafe posture. He should be standing on a rung and should be wearing fall protection.

Considerations…
- Planning
- Alternatives
- Communication
The portable stairs on the right are able to be reused on several projects while allowing the workers a safer angle for ascent and descent compared to the gang-ladder on the left.

The lift on the right allows a worker to reach heights while providing a safe working platform and small footprint in the hallway compared to the very tall stepladders on the left that are still not tall enough for the workers to safely reach their job tasks.
