Process industry manufacturing technicians run processes involving high hazard inputs to produce products that meet specifications. This may include chemical-based products, stabilised crude, ethane, butane, methane, and hydrogen. The working environment is highly controlled due to the use of high hazard chemicals. Technicians must follow high-level safety systems. Typically, production is on a large scale using a continuous process. This usually means operations are 24 hours per day, seven days per week. Technicians may be required to work shifts.

Technicians run and maintain the process or processes in line with operational parameters. They conduct quality assurance, resolving or escalating any issues, and complete records. Maintaining workplace safety by following health, safety and environmental risk and management systems is a vital part of the role. Preparing equipment for maintenance and bringing equipment back on line is also part of the role. They also support risk assessment, improvement activities, and audits.

On a daily basis, they work with other members of the process team. They also have contact with people in other teams for example, laboratory, maintenance, process engineering, supply chain, and warehouse. They may also have contact with external people such as, customers, service providers, and regulators.

They must ensure that the process and products meet quality specifications and are produced to schedule. They must work to external manufacturing regulations to protect the process, product, plant and equipment, company employees, and the environment. They must also consider sustainability. They may need to wear specialist PPE to protect the product or themselves. This may include, safety glasses, chemical resistant gloves, suits, and footwear, and breathing apparatus. They may work alone or part of a team. They work with minimal supervision, taking responsibility for the quality and accuracy of their work.
