4.3.HOOK AND LINE
4.3.1. INTRODUCTION Hook and line (H&L) provides an MA IEDD operator with the ability to semi-remotely conduct positive actions. Such actions include moving IED component parts to help ensure that they are safe to manually handle, and separating components such as electrical links or parts of an explosive chain during an RSP. H&L requires an IEDD operator to leave the safety of the CP and enter the explosive danger area in order to manually place or connect the line in a non-intrusive manner. The IEDD operator then returns to the CP prior to the line being pulled and the positive action conducted. It can be used when ROVs are not available, or when their use would not be suitable due to the operational conditions. H&L equipment is an essential component of any MA IEDD team. There are many commercially available kits that meet a range of requirements and budgets. However, the majority of items in an H&L kit can be procured or manufactured locally, with limited need to resource specialised components externally. 4.3.2.WHY IS THE USE OF HOOK AND LINE ‘GOOD PRACTICE’? H&L complies with the IMAS 09.31 guiding philosophy of ‘preservation of life’ by observing the IEDD general principles: “Remote (if available) and semi-remote actions should be conducted to neutralise and/ or dispose [of] IEDs”, and “All IED components should be moved remotely or semi-remotely prior to manual handling.”
ADVANTAGES OF HOOK AND LINE
• Provides the ability to conduct positive actions safely when ROVs are not available;
• Highly adaptable with a wide range of utility;
• Can be used on multiple target objects concurrently;
• Relatively inexpensive;
• Limited / no import issues;
• Can often be locally procured;
• Minimal / easy maintenance and cheap to replace damaged items;
• Can be transported manually or in small vehicles.
DISADVANTAGES OF HOOK AND LINE
• The IEDD operator must enter the danger area to set up the H&L equipment. This may require some degree of interaction with the device, or its immediate surroundings;
• A physical link is required between the CP and device, which can restrict the location of the CP;
• Using H&L to conduct component separation during an RSP presents greater risk than neutralisation by disruption or destruction in situ.
