You need to use a ladder to access a roof but the only place to rest the ladder is on a run of plastic gutter. What two things should you consider doing?

Resting the ladder against the gutter, climbing it and quickly tying it off

Using a proprietary stand-off device that allows the ladder to rest against the wall

Resting the ladder on a gutter support bracket

Positioning the ladder at a shallow angle so that it rests below the gutter

3 / 47

An outdoor tower scaffold has stood overnight in high winds and heavy rain. What should you ensure before the scaffold is used?

4 / 47

When can someone who is not a scaffolder, remove parts of a scaffold?

Only if the scaffold is not more than two lifts in height

19 / 47

If using inflatable airbags as a means of fall arrest, what must you ensure with regard to the inflation pump?

It must be switched off from time to time to avoid over-inflation

It must be switched off when the airbags are full

It must be electrically powered

20 / 47

Why is it dangerous to use inflatable airbags that are too big for the area to be protected?
