The measurements of a staircase according to the building site

My home (I build or I renovate my house)

I measure my staircase as I see fit, knowing that safety standards exist and provide me a basic level of safety as with the NF P21-210 standard.

  • Recommended step height : between 170 and 210 mm
  • Recommended step tread: between 210 and 270 mm
  • Recommended step width : > 700 mm
  • Recommended guard-rail height : minimum 900 mm (minimum 1000 mm for a mezzanine)
  • Free guard-rail design or according to NF P01-012

My property (I rent an apartment, a house, a building, a store)

Fire escapes

The safety against fire in France are governed by the Regulation of 25 June 1980 of the building code. These measures are applicable to all institutions, regardless of the age of the buildings and facilities. ‘s Rules relating to stairs are: CO34 to CO42 – General rules CO49 and CO56 to – Clearing stairs

Some concepts to know:

Clearing : In case any part of the construction for the escape route of the occupants (door, exit, entrance, circulation area, staircase, passage…).
The type of institution : the establishment is classified according to its nature of business.
The type of establishment : depending on the size of the workforce at the facility, the stairs in their number and dimensions will be differentiated.
Unit pitches : the width of the stairs is defined as a function of passage units ranging from 600 to 900 mm. When a staircase comprises of only two passage units, the width of the clearance is increased from 600 to 900 mm and 1200 mm to 1400 mm.

 

« The design of the stairway evacuation will be following the advice of the committees site security of these four concepts and analysis by our height specialists. ».
