Transfer of heat through the air by electromagnetic waves
Air = 21%

As little as 3 minutes in a home
Roll Over – Re-ignition of carbon in smoke
Carbon in smoke re-ignites around 1,100 degrees
Back Draft – Introduction of Oxygen to a suffocating fire
Home fires begin to suffocate in about 3 minutes
Early detection and fire department notification
Prevents spread and growth – Ceiling tiles
Utilize power strips with a surge protector
Windows and doors when leaving the office
