A rolling scaffold is 9 feet high and not guyed or tied. What is the minimum base dimension?
- a.3 feet✓
- b.9 feet
- c.6 feet
- d.1 foot
The base is not less than one-third of the height, 9 ÷ 3 = 3 feet. One foot is too narrow, 6 feet is two-thirds, and 9 feet is the full height.Title 8 §1646(a)

- a.They are allowed when the height is under six feet
- b.They are allowed when tied off with rope
- c.They are not placed there to gain height✓

Ladders or other unstable objects are not placed on top of rolling scaffolds to gain greater height. Rope, a low height and holders do not make it permitted.Title 8 §1646(f)

- b.To stage a long run of exterior glazing
- c.Only to work at the opening where the jack is placed✓
- d.To store lites at the window opening for later
Window jack scaffolds are used only for working at the window opening where the jack is placed, and jacks do not support planks between jacks. A run of staging or glass storage is not the purpose.Title 8 §1654(a), (b)
How many employees may occupy a window jack scaffold at one time?
- a.Two employees
- b.One employee✓

- b.No protection when the work is brief and low
- c.A warning cone placed on the floor below
- d.A rope tied from the worker to the glass
Window jack scaffolds have guardrails unless safety belts and lanyards are provided and used. Doing without, a cone and a rope to the glass do not protect against a fall.Title 8 §1654(c)
When are danger signs used?
- a.Only where an immediate hazard exists✓
- b.Whenever any general caution is wanted
- c.Only after an accident has happened
- d.Only when visitors come to the site
Danger signs are used only where an immediate hazard exists, and employees are instructed that they indicate immediate danger. A general caution belongs on a caution sign, an accident does not trigger the rule, and a visitor's presence is not the test.Title 8 §3340(c)

- b.They are removed or covered promptly✓
- c.They stay up until the project closes out
- d.They are turned around to face the wall
Temporary signs are visible during work and are removed or covered promptly when the hazard no longer exists. Leaving them up until closeout keeps a false warning, turning them to face the wall is not removal or covering, and painting them white is not the rule.Title 8 §3340(a)(3)
