3. If it is a multipurpose stair tower, have provisions been made for falling object protection?

1. Are rest platforms less than 12 feet apart vertically?

2. Are steps a minimum of 16 inches wide and aligned vertically in each flight?

1. Are stringers installed at a 40 to 60-degree angle?

4. Does the stair rail/handrail system have a surface that prevents injuries such as punctures or lacerations to employees?

5. Are all handrails attached in a manner that does not create a projection hazard?

6. Do handrails provide an adequate handhold for employees to grasp to avoid falling?

1. Have falling object hazards been eliminated according to 1926.451?
