|
What can impact the intensity of smoke in the cabin? |
Rate of smoke production And Available ventilation |
|
|
What can cabin crew do for fire prevention? |
- eliminate potential hazards - detect source of smoke / fire early - check for paper/debris in bins - pick up excessive paper on galley/lav floors/floor vents - check for foreign objects in coffee maker (ie. Plastic, metal, etc.) - clean up liquid spills on coffee warmer pad - shut off electrical supply to malfunctioning equipment - ensure lavs tidy and smoke detectors unobstructed - if lav has smoke detector sound, investigate asap, take action as needed (ie. Appropriate fire fighting procedures) - no liquids behind lav mirrors - waste bin flaps closed but still accessible in order for better fire detection/firefighting if needed - enforcing no smoking - check correct use of seat power supply/charging |

What are different ways to detect fire ? |
- fire not always obvious - smoke and flames more always visible as open flame Signs: - fumes / unusual odors - electrical malfunction (ie. Circuit Breakers tripping) - noises (popping / snapping / crackling which may indicate electrical arcing) - hot spots should be investigated (ie. In sidewalls, floors, panels) - PAX or FAs suddenly developing eye irritations, sore throats, headaches) - can indicate presence of gas fumes not yet reaching level where they are visible) |

What is flash point? What is flash over? |
Flash Point: Lowest temperature that a combustible gives off vapors that will ignite when a source of ignition or fire is applied to the vapours
Flash Over: - Occurs when flash point is reached - Occurs when combustible gases become heated to the temperature where flames flash over the entire area - this is why speed is imperative in an evacuation when fire is present |
