How to write a method statement
Prepare to write by conducting a risk assessment--an in-depth examination of the task or process.
Identify the work hazards (those that could potentially cause poor health or personal harm) that are inherent in the task. Analyze what has been done about these hazards and if these measures are enough to reduce the harm potential to an acceptable level.
Decide what additional measures need to be taken to reduce harm if an acceptable level has not been met. Begin to write your method statement, starting at the header.
