An organisation's culture can have as big an influence on safety outcomes as the safety management system. 'Safety culture' is a subset of the overall organisational or company culture. Many companies talk about 'safety culture' when referring to the inclination of their employees to comply with rules or act safety or unsafely. However we find that the culture and style of management is even more significant, for example a natural, unconscious bias for production over safety, or a tendency to focus on the short-term and being highly reactive. Success normally comes from good leadership, good worker involvement and good communications.
