Using two independent physical controls to secure a portable gauge in a vehicle is the correct approach because it significantly enhances safety and accountability. This method ensures that the gauge is properly immobilized, reducing the risk of accidental exposure or unauthorized access during transport. The use of two independent controls creates redundancy, making it less likely for the gauge to be dislodged or accessed by someone who should not be handling it.

In contrast, securing the gauge in a locked case may provide a basic level of protection; however, relying solely on this method can be insufficient if the case itself could be accessed or compromised. Likewise, placing a gauge in the vehicle's trunk or leaving it unsecured on the open floor does not provide the robust security necessary for hazardous materials, which could lead to potential safety risks or legal ramifications. Hence, implementing two independent controls establishes an effective deterrent against both accidental and intentional breaches of safety protocols.
