What is the first action to take before operating unfamiliar equipment?

Reading the manufacturer's manual is essential before operating unfamiliar equipment because it provides critical information tailored to that specific equipment. The manual outlines how to safely operate the device, including operational procedures, safety warnings, and troubleshooting steps. This foundational knowledge is crucial for ensuring not just effective operation, but also the safety of the operator and others around them.

While consulting a colleague for guidance can be beneficial, it relies on the colleague's knowledge rather than the specific instructions from the manufacturer. Visual inspection is important but may not reveal all operational procedures and safety protocols required for safe use. Plugging in the equipment without prior knowledge from the manual could lead to accidents or equipment damage. Thus, familiarizing oneself with the manufacturer's manual is the most responsible and informed first step.
