Electrical safety basics involve preventing electric shocks, burns, and fires by maintaining equipment, using proper tools, and following safety procedures. Key principles include de-energizing circuits before work (lockout/tagout), wearing PPE (insulated gloves), grounding tools, keeping water away from electricity, and ensuring only trained personnel handle electrical repairs.  Here are the fundamental electrical safety basics: De-energize Before Working: Always turn off, lock out, and tag out power sources before repairing or maintaining electrical equipment to prevent accidental...
