In safety practice, what must be done to hot assemblies and tools to communicate their condition?

• A. Disposed of
• B. Set aside until they are cool
• C. Labeled with an appropriate sign
• D. All of the above

Answer: (C)

Clear warning that travels with the item is essential for safety. The best practice is to label hot assemblies and tools with an appropriate sign, such as “Hot Surface” or “Caution: Hot,” placed where it is clearly visible before anyone touches it. This makes the hazard immediately understandable to anyone who encounters the item, even if the original operator isn’t nearby or if the item is moved. Relying on simply setting something aside to cool can fail to communicate the danger to others and might lead to accidental contact while the item is still hot. Disposing of the tool or assembly isn’t required unless it’s unusable, so labeling remains the reliable, standard way to convey the current condition and prevent burns.
