resctrictive access to power switch

[LONDONDERRY]

The company I work at designs kiosk systems and recently a customer has requested we restrict access rom the public to the ac
on/off switch. Currently we have lock boxes on the external ac power cords to prevent the public from pull out the plug, but I don't think you can completely restrict access to prevent shut off because of safety issues. Can someone weight on this matter is there a safety guidelines I can read up on?
