Communication allows people, tasks, processes and systems to interact purposively and co-operatively to achieve health, safety and environment (HSE) objectives. The way we communicate about safety will influence whether or not people will understand and participate in the safety process, and the language we use will often determine whether the process is accepted or rejected. Merely training people to work safely will often not be sufficient. It may be necessary to provide forms of motivation and publicity to encourage them to take responsibility for their own health and safety, and that of others. The methods used will need to create an atmosphere that promotes safe behaviour, and reminds and reinforces the benefits for employees and the organisation of working safely.
