A contractor is using a ladder to access a work platform. According to Cal/OSHA, how far above the landing must the side rails of a portable ladder extend?

  1. AAt least 2 feet
  2. BAt least 1 foot
  3. CAt least 3 feet
  4. DAt least 4 feet
Show answer & explanation

Correct answer: C. At least 3 feet

Cal/OSHA requires that the side rails of a portable ladder used to access an upper landing surface extend at least 3 feet above that landing surface. This provides a secure handhold for safe transition.

Why the other options are wrong

  • A. This extension is insufficient for safe egress and ingress.
  • B. This extension is insufficient for safe egress and ingress.
  • D. While safer, this is not the minimum required extension by Cal/OSHA.

Cal/OSHA Ladder Extension (Portable)

Side rails of portable ladders used for access must extend at least 3 feet (0.91 meters) above the upper landing surface.

  • Applies to portable ladders
  • Used for access to an upper landing

Memory trick: Three feet high, reach for the sky, safely you'll climb!
