Product Overview

Summary: This SOP sets out a structured, preventive maintenance regime for metal fabrication equipment to keep workers safe, minimise unplanned downtime, and protect expensive plant assets. It provides clear, step-by-step guidance for inspections, servicing and record-keeping so your workshop can operate reliably, efficiently and in line with Australian WHS obligations.

Metal fabrication workshops rely on high‑energy equipment such as presses, guillotines, CNC plasma and laser cutters, welders, grinders and overhead lifting gear. When these machines are not maintained systematically, the risk of mechanical failure, entanglement, ejection of parts, electrical faults and fire increases dramatically. This Preventive Maintenance for Metal Fabrication Equipment SOP establishes a consistent, defensible method for inspecting, servicing and verifying the safe condition of all key plant used in cutting, forming, joining and handling metal products.

The procedure translates manufacturer recommendations, Australian Standards and WHS duties into practical maintenance schedules, checklists and responsibilities tailored to a busy fabrication environment. It helps businesses move away from reactive, breakdown-based maintenance and towards a planned, risk-based approach that reduces injuries, protects workers from hazardous failures, and keeps critical equipment compliant with guarding, isolation and electrical safety requirements. By adopting this SOP, organisations can demonstrate due diligence, extend equipment life, and support smooth production flow without sacrificing safety or legal compliance.

The document is designed for Australian workshops of all sizes—from small fabrication shops through to large manufacturing plants and engineering facilities. It supports integration with existing maintenance management systems (CMMS), contractor arrangements and WHS management systems, providing clear guidance on inspections, defect reporting, lock out–tag out during maintenance, and documentation standards that will stand up to regulator or client audits.

Key Benefits

• Reduce the likelihood of mechanical failures that can lead to serious injuries, near misses and costly equipment damage.
• Ensure compliance with WHS legislation and Australian Standards governing plant, machinery guarding, electrical safety and lifting equipment.
• Standardise preventive maintenance tasks, intervals and responsibilities across all metal fabrication equipment.
• Extend the service life and reliability of high‑value machinery, reducing unplanned downtime and emergency repair costs.
• Improve audit readiness by embedding consistent inspection records, maintenance logs and defect close‑out documentation.

Hazards Addressed

• Mechanical failure of presses, guillotines, rollers and folding machines leading to crush and amputation injuries
• Failure or bypassing of machine guarding and interlocks on cutting and forming equipment
• Unexpected start‑up of equipment during maintenance due to inadequate isolation or lock out–tag out
• Ejection of workpieces, tooling or fragments from poorly maintained cutting, drilling and grinding equipment
• Electrical faults, damaged leads and inadequate earthing on welders, plasma cutters and power tools
• Overheating, sparks and fire risks associated with poorly maintained welding and cutting equipment
• Failure of lifting equipment such as overhead cranes, hoists, chains and slings due to lack of inspection
• Excessive vibration, noise and ergonomic strain from worn bearings, misaligned components and unbalanced rotating parts
• Oil, coolant and hydraulic fluid leaks creating slip hazards and potential environmental contamination
