What is the primary concern when transporting hazardous materials that are volatile?

Controlling the temperature is crucial when transporting hazardous materials that are volatile. Volatile substances can easily vaporize or change state if not maintained within specific temperature ranges. When temperatures rise, the pressure within the container can increase, potentially leading to leaks, ruptures, or even explosions. Additionally, a substantial change in temperature could enable these materials to reach explosive concentrations in the air, creating a hazardous situation.

While maintaining a steady speed, keeping materials away from water, and avoiding sharp turns are all relevant safety considerations during transport, they do not address the specific risks associated with the volatility of certain hazardous materials. Water could react with some substances, but it does not directly affect all volatile materials in the same way that temperature does. Similarly, while sharp turns and speed can impact the stability of a load, they are less critical compared to the necessity of temperature control for volatile materials.
