Reminder on how to calculate the correct and safe ladder!

First of all, you should pay attention to the following parameters:

• The slope for residential premises is within 30-40 degrees.
• The number of steps is from 3 to 16 for two-march models and 18 for single-march models.
• The size of the site must be no less than the width of the marches leading to it.
• Tread width 290 mm, fluctuations are allowed +/- 30 mm.
• Riser height - 170 mm is considered the standard, nevertheless, the interval of 140-200 mm does not go beyond the norm.
• Pitch is ideal 620 mm.
• The width for a regular staircase to the second floor is at least 800 mm.
