OEM Pneumatic Lockouts are devices used in industrial applications to isolate energy sources, particularly in pneumatic systems. These systems use compressed air to power various machines and tools, and during maintenance, it is crucial that all energy sources are safely locked out to prevent unintended startup. The lockouts are specifically designed to block the flow of pneumatic energy, ensuring that the equipment remains inactive until maintenance workers can safely work on the machinery. The OEM aspect refers to the fact that these lockouts are often custom-designed or made by the original equipment manufacturer to fit specific machine requirements.
