1.5.MANAGEMENT OF NON-EXPLOSIVE HAZARDS

The frequency and complexity of non-explosive hazards in an urban environment pose significant challenges to an MA organisation. Considering the situation shown in Image 15, if the threat assessment specifies a need to search the electrical boxes, then the clearance plan would need to specify which procedures in the organisation’s SOPs would be applied. Other hazards that need to be considered are the following:
• Questionable structural integrity of buildings;
• Chemicals and substances, domestic or industrial, that are hazardous to health may be present and not in a controlled state; • Spaces in the worksite that are hazardous environments and pose additional risks due to their construction. These are generally referred to as ‘confined spaces’; • Areas of the worksite at height, where risks can arise from lack of fall protection, and fragile surfaces. These areas are generally referred to as ‘working at height’; • Infrastructure and bulk substances that may enhance the effect of planned or un-planned explosions or cause additional hazardous environments if damaged by explosions. These are generally referred to as ‘secondary hazards’ and may consist of bulk fuel, gas and chemical storage or electricity supply.
