Stairwell Pressurization

• Proven Success
• 27 Portable Gas powered Fan
• 24,000 cfm cubit feet per minute
• Placement
• 4 to 6 feet back
• 80 Angle

15
Stairwell Pressurization

• Clears Stairwell lt 60 seconds
• Open Bulkhead then Close
• Pressure Equalized at Fire Floor

16
Wind NOT a Factor

• Fan Pressure will Push Smoke Heat
• Back into Fire Apartment

Size Up

• The Ventilation Profile
• Outside Observations
• Inside Observations
