Final answer:
Double-stacked loads should be avoided as a good practice to ensure safety, similar to precautions taken with other hazardous materials and high-risk environments.
Step-by-step explanation:
It is good practice to avoid handling double-stacked loads to ensure safety in environments where materials are being handled, such as warehouses, construction sites, and laboratories. This recommendation is analogous to safety precautions in other fields that aim to prevent accidents and ensure a safe working environment. For instance, in handling fissile materials, they should never be double-stacked due to the risk of criticality accidents. When working with high-power electric circuits, a common safety mantra is to work 'one-handed' or 'keep one hand in your pocket' to minimize the risk of electric current passing through the heart. Moreover, it is critical to pay attention to guidelines such as not attempting certain procedures when they may lead to unsafe conditions, which is exemplified by the provided warning about perspective drawing techniques.
