Appleseed Engineering provides the facilitation services necessary to run successful risk workshops. Facilitated workshops are the recognised method of effective risk minimisation for the construction, operation and maintenance, and demolition of infrastructure. Different tools are utilized for the various design elements.
The tools that Appleseed uses are:
CHAIR – Construction Hazard Assessment Implication Review
The CHAIR tool is optimised for ensuring that the design provides the optimum safety in the construction and demolition phases. This tool is recommended for plant modifications as well.
HAZOP – Hazard and Operability workshop
HAZOPs look at the single line diagrams and/or the Process and Instrumentation Diagrams, to establish that the main plant items are configured to ensure the plant can be operated and maintained with as little risk as possible. It also ensures the plant itself will have minimum risk of being damaged.
CHAZOP – Control Hazard and Operability workshop
CHAZOPs concentrate on the instrumentation and control systems. Focusing on the effect of a deviation/failure of any element, CHAZOPs ensure that appropriate back mechanisms are provided for the safest plant operation.
