Hi, can the emergency stop be used for lock out point (controlled entry) to enter a machine cell for short term activity like cleaning, changing a weld rod, etc. Does any standard restrict such use of lock out point from ANSI/CSA, ISO standard.

The emergency stop device is not an energy isolating device.

When the tasks specified are routine, repetitive, and integral to the production process, or traditional lockout/tagout prohibits the completion of those tasks, alternative methods of control that are based on risk assessment (5.4.1) and that provide effective personal protection shall be used. The key is "BASSED ON RISK ASSESSMENT (DOCUMENTED) and PROVIDE EFFECTIVE PERSONAL PROTECTION SHALL BE USED
