2. THE RISK MANAGEMENT PROCESS
2.1 Identifying the hazards
The first step in the risk management process is to identify the hazards associated with demolition work. Examples of demolition hazards include:
• unplanned structure collapse
• falls from one level to another •falling objects
• the location of above and underground essential services, including the supply of gas, water, sewerage, telecommunications, electricity, chemicals, fuel and refrigerant in pipes or lines
• exposure to hazardous chemicals – These may be present in demolished material or in the ground where demolition work is to be carried out( contaminated sites)
• hazardous noise from plant and explosives used in demolition work
• the proximity of the building or structure being demolished to other buildings or structures.
2.2 Assessing the risks
Under the WHS Regulations, a risk assessment is not mandatory for demolition work however it is required for specific situations, for example when working with asbestos or explosives. In many circumstances a risk assessment will assist in determining the control measures that should be implemented. It will help to:
• identify which workers are at risk of exposure
• determine what sources and processes are causing that risk
• identify if and what kind of control measures should be implemented
• check the effectiveness of existing control measures.
When assessing the risks associated with demolition work consider the following:
• the structure to be demolished and its structural integrity
• the method of demolition including its sequencing
• the scheduling of the work
• the layout of the workplace, including whether there are fall hazards both for people and objects
• what plant and equipment will be used and the skill and experience required by the people who will use it safely
• what exposures might occur, such as to noise or ultraviolet( UV) rays
• the number of people involved
• local weather conditions.
