Hazard Analysis Techniques for Mobile Construction Robots*

35 This paper introduces the problem of safety for mobile construction robots and explains the concept of a "hazard " in safety analysis. The well known Safety Lifecycle Model is described. This model is then expanded to illustrate the hazard analysis process in more detail. The documents required for the hazard and risk analysis are detailed, and three well known hazard analysis techniques reviewed- HAZOP, FMECA and Fault Tree Analysis. The shortfalls of these techniques are described, and a new technique known as Consequence Led Analysis of Safety and Hazards (CLASH) is proposed
