Submitted 2018-12-18 11:59:03 Almost every type of construction work commences with digging into the ground hydro flask standard mouth 18 oz sale , and in some cases this can mean a long way down. It is known that there are millions of miles of buried services in the UK, including electricity, telecoms, water hydro flask 18 oz sale , gas, and fibre optic cable, and they can be almost anywhere. In fact, best practice suggest that you should assume that there are buried services in the area in which you are going to dig hydro flask 21 oz with sport cap , so you need to use the correct tools to locate them before a spade touches the ground.

The correct tools are the CAT (Cable Avoidance Tool) and the Genny (Signal Generator). It is possible to use the CAT on its' own, but for all practical purposes it should be used in conjunction with the Genny in order to locate and identify as many services as possible.

The CAT detects signals that radiate naturally from metallic services, or in conjunction with the Genny it can detect a signal that the Genny applies to the buried service. The CAT can be operated in three different modes. These are the power mode, the radio mode hydro flask 21 oz sale , and the Genny mode. The CAT can detect most buried cables and pipes, but some services and conductors do not radiate a signal 鈥?even live ones. This is where there is plastic pipework.

In the power mode, the CAT is used to detect power signals that are being radiated by cables which are loaded. This is used to detect buried electricity cables.

In the radio mode the CAT detects VLF radio signals that are being re-radiated by buried metallic cables and pipes, that is gas hydro flask standard mouth 24 oz sale , water, and phone and communication lines.

When in the Genny mode the CAT detects a tone that is radiated to the buried conductor by the Genny. This mode is used to detect and locate all services that are a direct connection to the source 鈥?in other words gas valves, water valves, and plug sockets.

The Genny signal transmitter works in conjunction with the CAT and for optimum accuracy of location is used to supply a direct connection signal mode. It can also produce an induced signal mode if direct connection access is not possible. It works very well for locating pipes and cables from a direct source such as plug sockets for instance.

If the Genny cannot connect directly hydro flask standard mouth 24 oz bottle , or signal clamping is not possible, the Genny can be used in induction mode which induces a signal into a cable or other underground service which can then be detected by the CAT. This is perfect for tracing a cable or service where the direct location of exact access points is unknown. Signal clamping mode applies a signal to a pipe or live cable up to 76mm in diameter without interrupting the supply. Live cable connectors can be used to apply the Genny signal directly to a live cable.

As can easily be seen, the use of the CAT and Genny in all the different modes need thorough learning and understanding of how each piece of equipment works and what it does in the various modes, and also what the limitations of the equipment are. This is why a CAT and Genny course is so important for those whose job it is to locate buried services. CAT and Genny training will enable operatives to fully understand the theory of electromagnetism and also learn all of the associated health and safety aspects that combine with working with underground services. This includes HSG47 advice from the HSE. HSG47 is not a legal requirement but nonetheless covers a considerable amount of advice which hydro flask sale 24 oz , as the HSE itself says, will ensure that you are complying with the law if you follow it.

There are various qualifications that need to be obtained for operatives to work in some areas, and courses can be found in EUSR CAT and Genny training which can result in operatives being awarded an EUSR card which is similar to the CSCS card. Indeed, the two organisations are now affiliated in regard to their cards so that award of one or the other will allow operatives to work in and around electricity substations.
Cycling is an excellent way to stay healthy hydro flask standard mouth sale , exercising muscles and providing aerobic benefits at the same time, as well as giving a person opportunity to enjoy fresh air and (hopefully) sunshine when riding outdoors. But as many men know, there can be some male
