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.
