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 .
