6.5.1 Emergency Egress Routes

To facilitate evacuation consider these measures.

• Provide positive pressurization of stairwells and vestibules.
• Provide battery packs for lighting fixtures and exit signs.
• Harden walls using reinforced CMU block properly anchored at supports.
• Use non-slip phosphorescent treads.
• Do not cluster egress routes in single shaft. Separate them as far as possible.
• Use double doors for mass evacuation.
• Do not use glass along primary egress routes or stairwells.
