Safety Procedures: True or False?

Platforms need only be inspected once a year.

You shouldn’t work on a platform with a slippery floor.

It’s safe to carry flammable liquids on platforms if there’s a fire extinguisher.

You should maintain voice communication with someone in the building while working on a powered platform.
