FIRE SAFETY PRESENTATION
Flash point of normal pentane = -49°C (-56°F)
(Low flash points mean that flammability can become a concern
even at room temperature.)
Lower Flammability Limit (LFL) = 1.4% by volume
Upper Flammability Limit (UFL) = 8.3% by volume
Mixtures containing less than 1.4% by volume (too lean) or greater than 8.3 % by volume
(too rich) of pentane in air cannot burn.
Vapor density = 2.5
- Vapor density<1 means that the gas is lighter than air and will rise.
- Vapor density>1 means that the gas is lighter than air and will sink.
Pentane Blowing Agent
- Vapor density<1 means that the gas is lighter than air and will rise.
- Vapor density>1 means that the gas is lighter than air and will sink.
