A safe operating procedure (SOP) is a document that sets out the approved method of operating a particular machine or carrying out a task.

In workplaces that have large static machines, SOPs are often put on a wall beside the machine to remind workers what the start-up and shut down procedures are, and what to do in the event of a malfunction or problem.

But SOPs can also be written up for hand held tools and work processes, particularly when they involve the use of personal protective equipment or special techniques to avoid injuries.

SOP layout

Although there are various ways of developing an SOP, they generally follow the same layout.

You'll notice that the SOP is divided into the following components:

• Activity description - defining the task.
  
  
• Potential hazards and safety controls - listing the main hazards and how to deal with them (see Section 3 for more details on what a 'hazard' is)'.
  
  
• Pre-start checks - providing a set of safety checks to work through before turning on the equipment.
  
  
• Operational procedure - setting out the main steps involved in using the equipment safely.
