Rules & regulations

Two Storey / double deck structures larger than 500m2 must provide evacuation calculations for the first floor following the Spanish building regulations (CTE). Please click here to view the Spanish CTE (Código Técnico de la Edificación).

If evacuation time is less than 2.5min (25m is considered less than 2.5min evacuation time):

• The structure around emergency staircases (pillars and buttress) must be treated for fire resistance. R-30
• 50kg fire extinguishers must be provided on the evacuation route near stairs on second deck
• Emergency and evacuation assistants must be placed in each emergency staircase

If evacuation time is more than 2.5min there are two options:

• The entire structure of the upper level must be treated for fire resistance, or
• The number of emergency staircases is increased until evacuation time is reduced to be below 2.5min. Subsequently, the above rules apply for evacuation times less than 2.5min
