What should operators do before attempting to clean an additive manufacturing machine?

Turning off the power before cleaning an additive manufacturing machine is a critical safety measure. This ensures that operators are not exposed to any moving parts or electrical hazards while cleaning the equipment. It eliminates the risk of accidental startup, which could lead to injuries or damage to the machine. Establishing this practice promotes a safe working environment and allows operators to clean effectively without the concern of the machine being operational.

Other options, while seemingly relevant, do not address the immediate safety protocols necessary for cleaning equipment. Wearing a lab coat may provide protection from dust but does not mitigate safety risks related to machine operation. Cleaning with water may not be appropriate for all machines, especially since certain components may be sensitive to moisture. Using a vacuum could be beneficial in removing debris but should only be done after ensuring that the machine is safely powered down.
