Danger Isolate Supply Before Opening Safety Sign
The Danger Isolate Supply Before Opening Safety Sign is designed to protect workers and contractors from the serious risks associated with live electrical equipment. It serves as a critical reminder that all power supplies must be switched off and isolated before opening panels, enclosures, or machinery.
Why You Need This Sign

Opening switchgear, control panels, or machine guards without isolating the supply can lead to life-threatening accidents. This warning sign ensures compliance with workplace safety procedures and reinforces lockout/tagout (LOTO) requirements.
