This risk assessment document identifies hazards associated with laying blockwork using access scaffolding and proposes control measures. It addresses six specific tasks: 1) vehicle and plant movements for block delivery, 2) use of access scaffolding and working platforms, 3) loading out blocks and mixing mortar, 4) laying blockwork, 5) disposal of concrete, and 6) worker exposure to direct sun. For each task, the document identifies hazards, assesses initial risk level, lists control measures to reduce risk, and notes any remaining risks. The overall goal is to reduce risks from falls, manual handling injuries, vehicle collisions, cement burns and heat exposure during block laying activities.
