It retains most of the contents of the first edition, starting with the challenging first chapter titled 'Open Your third eye' exhorting readers to experience the world around them with a fresh expanded awareness of the hazards from various sources, so that they may learn to assess their importance and potential for injury to themselves and others, and damage to other assets or the environment etc., and to eliminate the harmful effects of the risks or at least minimise their adverse consequences. It has new chapters on work at height and ergonomics … and free access to author’s papers.
