Product Overview

Summary: This Thermal Processing Safe Operating Procedure sets out clear, practical steps for safely operating ovens, kilns, dryers, pasteurisers, furnaces and other heat-treatment equipment. It helps Australian businesses control burn, fire, explosion and product quality risks while maintaining compliance with WHS duties and relevant food, manufacturing and engineering standards.

Thermal processing sits at the heart of many Australian operations, from food and beverage plants and commercial bakeries to metal fabrication, ceramics, chemical processing and waste treatment. With high temperatures, pressurised systems, combustible materials and complex automation, the risk profile is significant – ranging from burns and heat stress to fires, explosions and major product recalls. This Thermal Processing Safe Operating Procedure provides a clear, step-by-step framework for planning, operating and shutting down thermal equipment in a way that protects workers, product integrity and plant assets.

Developed for the Australian WHS environment, this SOP translates regulatory expectations and industry best practice into practical on-the-floor instructions. It covers pre-start checks, safe start-up and shutdown sequences, control of temperature and dwell time, monitoring of critical control points, and robust responses to alarms or process deviations. By implementing this procedure, your business can reduce the likelihood of serious incidents, demonstrate due diligence under WHS legislation, and ensure consistent, repeatable processing outcomes across shifts, sites and contractors.

Key Benefits

• Ensure safe, consistent operation of ovens, kilns, furnaces and other thermal equipment across all shifts.
• Reduce the risk of burns, fires, explosions and heat-related illnesses through structured hazard controls.
• Improve product quality and shelf life by standardising temperature, time and verification steps.
• Demonstrate WHS due diligence and support compliance with Australian standards and food safety requirements.
• Streamline training and competency assessment for new operators, contractors and relief staff.
