Product Overview

Summary: This Metal Detection System Use SOP sets out clear, step‑by‑step instructions for safely and effectively operating fixed and conveyor-based metal detectors in Australian workplaces. It helps you protect workers, safeguard product quality, and demonstrate due diligence under WHS and food safety regulations by standardising how metal contamination risks are controlled and responded to.

Metal detection systems are critical control points in many Australian industries, particularly food and beverage, pharmaceuticals, packaging, and bulk materials handling. When they are not set up, operated, or verified correctly, businesses face serious risks: physical contamination of product, product recalls, brand damage, regulatory non‑compliance, and potential injury from interacting with moving plant and high‑voltage equipment. This Safe Operating Procedure provides a clear, practical framework for how metal detectors are to be used, tested, and maintained on site, so that frontline operators and supervisors know exactly what is expected of them on every shift.

The SOP covers the full lifecycle of use: pre‑start inspection, safe start‑up, verification with test pieces, normal operation, response to alarms and rejects, fault finding, and shutdown. It also details how to manage contaminated or suspect product, including hold, rework, and disposal decisions that align with HACCP and food safety plans where relevant. By implementing this SOP, organisations can demonstrate that their metal detection controls are systematic, repeatable, and defensible under Australian WHS and food safety law, while reducing downtime caused by false rejects, misuse, or equipment damage.

Whether you operate a small packing line or a large, automated facility, this document helps you integrate metal detection into your broader safety and quality systems. It clarifies roles and responsibilities between production, QA, and maintenance teams, embeds record‑keeping requirements for audits, and supports consistent training of new staff and contractors. The result is a safer workplace, more reliable contamination control, and stronger protection of your customers and your brand.
