Cyclohexamine is a liquid that possesses a strong fishy odor. Some properties of cyclohexamine are provided below:

Boiling point 275 F

Freezing point 0 F

Vapor density 3.4

Specific gravity 0.87

Flash point 90 F

Lower explosive limit 1.5%

Upper explosive limit 9.4%

Requirements:

a. In which range of temperature does the cyclohexamine exist as a liquid at ambient conditions?

b. If closed, steel drums containing cyclohexamine are involved in a fire at a manufacturing facility, would you expect them to rupture when the surrounding temperature reaches 350 F?

c. Steel drums containing cyclohexamine rupture during a fire producing a varying vapor concentration at different locations. In the basement, concentrations were measured to be 12%. In the employee lounge, concentrations measured 5%. At that point, where would you most likely have ignition?

d. If steel drums containing cyclohexamine rupture during a fire and produce a vapor concentration in the air of 25% by volume will the vapor initially collect in low areas or diffuse upwards in the air?
