This CQ Dossier focuses on what constitutes an effective safety climate and how to improve workplace safety in general. Recent disasters such as the Grenfell Tower Fire incident illustrate the importance of safety in the work environment. At the Grenfell Tower, people escaped using a single staircase and while more than 65 people were rescued, an estimated 71 people died and countless others were injured. We draw on theory and research to describe how organizational practices can increase the level of workplace safety.
