4 Purpose and Scope Purpose The purpose of this document is to provide instructions for the safe use of tools and equipment. A tool is defined as a device or implement designed to carry out a particular function Types of tools include hand, electrical, pneumatic, hydraulic and explosive. Tools may also be classified according to their function (i.e. cutting, striking, heating, cooling, measuring, shaping, fastening, etc.) Scope This document has been developed for use by personnel performing tasks using tools or equipment. It provides step-by-step instructions on how to perform these tasks. Pre-requisites Some tools require specialised training or instruction to be completed prior to use. Training requirements will be detailed in the relevant sections of this document. Symbols Symbol Meaning DANGER This prompt is used when there is an immediate hazard that WILL result in severe injury or death if proper procedures are not followed. STOP or DO NOT This prompt is used to indicate a behaviour or action that COULD result in injury and/ or equipment damage. WARNING This prompt is used to warn against hazards that COULD result in injury and/ or equipment damage. Safety Requirements/ PPE List all safety precautions that users must comply with and all safety equipment that must be used while following the operations specified in this work instruction.
