Created by HSE experts, the safety climate tool (SCT) explores your workers’ attitudes and perceptions in key areas of health and safety, while guaranteeing anonymity.

It measures an element of safety culture – the ‘way things are done’ in your organisation. The results can help you identify areas for improvement and raise health and safety standards.
