Final answer:
Flammable gas storage guidelines are critical due to the physical and chemical properties of different gases, particularly with regards to density and how it affects fire hazards. Temperature plays a key role in the pressure within gas containers, illustrating why safety precautions like temperature limits are necessary. Regulations on storage limits, like the 1000 lbs limit, are established to mitigate these hazards.
Step-by-step explanation:
The question pertains to the safety guidelines and physical chemistry principles involved in the storage of flammable gases. Gas densities and how they relate to fire hazards are critical because different gases have different responses in the event of a leak. Flammable gases like methane, which is lighter than air, will rise, hence can be vented out through an upper window. Propane and butanes, on the other hand, are heavier and can collect near the floor, thus they pose a greater fire hazard as they are harder to remove from an enclosed space.
When considering the safety of gas storage, the warning about temperature is crucial because a high ambient temperature can increase the pressure inside a gas container, potentially leading to an explosion. As in the provided example, a gas initially at 24 °C and 360 kPa inside a can of 350 mL will experience an increase in pressure when the temperature rises to 50 °C. This is due to the direct relationship between temperature and pressure for gases described by the ideal gas law.
Exploring the dangers of gas storage is important in understanding why strict regulations are in place for the maximum allowable quantity of flammable gas in structures, such as the mentioned limit of 1000 lbs.
