  • The topmost rung must be at the exit level.
  • From an access height of 10,000 mm, the ladder shall be installed with an off set.
    The maximum length of a ladder section must not exceed 10,000 mm, an intermediate platform shall be designed as a resting platform for lengths in excess of 6,000 mm.
  • The off sets shall be arranged at equal intervals.
    It may, however, be designed at a different height on request or through the online configurator.
  • Distance of the rung-leading-edge of the ladder to the wall must be at least 150 mm.

Exemption:
