THE 48-HOUR INSTALLATION CHALLENGE

Emergency lighting installation typically requires 1-2 weeks:

“`
TRADITIONAL TIMELINE:
Day 1-2: Site assessment and design
Day 3-4: Equipment procurement
Day 5-6: Permit processing
Day 7-8: Scheduling coordination
Day 9-10: Installation execution
Day 11-12: Testing and certification
Day 13-14: Documentation and closeout

TOTAL: 2 weeks minimum
“`

Emergency situations demand compressed timelines:

• Fire marshal citations requiring immediate correction
• Building occupancy certificates pending
• Business opening deadlines approaching
• Regulatory compliance deadlines

48-hour emergency lighting installation feasibility depends on systematic execution, pre-positioned resources, and experienced coordination.

This article documents the hour-by-hour process 48Fire uses to deliver code-compliant emergency lighting installation within 48-hour emergency timelines.
