Safe Electrical Isolation in Practice: Where Food-Site Isolations Go Wrong
The real-world traps in electrical isolation on UK food production lines (hidden supplies, stored energy, shared panels and untested testers) and how to avoid them.
Why this matters in UK food manufacturing Food lines are dense with electrical supplies: main power, separate control circuits, UPS-backed PLCs, drives that store energy and equipment fed from more than one panel. Most electrical isolation incidents do not come from people skipping the procedure. They come from a supply nobody knew about, energy that stayed after switching off, or a tester that had failed. This toolbox talk covers those traps. The full step-by-step method is in the AFME resource AFME-ELE-ISO-001 12 Steps to Safe Electrical Isolation. In plain English Switching off is not the same as safe. Before you touch anything, you must be sure every supply is off, locked so nobody can switch it back on, and proved dead with a tester you have just checked works. 1. Remember the legal basics Electricity at Work Regulations 1989: regulation 12 (means of cutting off supply and isolation), 13 (precautions for work on equipment made dead), 14 (work on or near live conductors only when justified) and 16 (competence).HSE HSG85 sets out safe working practices, and GS38 covers safe test…
