Car DVD Installation Specialist Speaks Out – Why Audio Fans Shouldn’t Do DIY
One of the widest searched for items by most aftermarket DVD player buyers is a guide with information on how to install a car DVD player.But this can be the profitable nightmare of car DVD installation experts who have to come in afterwards to tidy up all the bits that the DIY fan missed or fix ‘little shortcuts’ that often turn into big problems if not caught in time.So what is it that DIY fans are doing wrong?The common mistakes that first-timers or amateurs make during installation include:# Overly hasty removal of existing entertainment systems# Improper Wiring# Poor connector choices# Voltage mismatch ** Overly Hasty Removal Of Existing Entertainment Systems **Most car DVD buyers are often so eager to get their new audio DVD players in that they yank out the old system, cut through the wiring and cabling where possible and, in general leave a horrible mess for experts to tidy up.Not only does hasty removal make extra work for installers it also prevents the customers from taking their new DVD player with them when they replace their car as the old system is unfit to put back into the car.** Improper Wiring **This can often too be attributed to haste and often cause major problems later on. Some more common things that car DVD installation experts see include:# People working around car interiors: Simply put most first-timers and DIYers do not want to bother with having to remove the seats, carpets and mats to install the wires. They leave the upholstery in the car when fitting the wires. It is impossible to do a proper fitment without first taking off the insides because you are invariably left with wires hanging loose.# People putting source and power wires together: It is also common for beginners to lay the source and power wires together. This results in inductance, which reduces the amount of currant being carried through the signal cables and drastically limits the capabilities of the person’s brand new powerful speakers.# Improper earthing: It is important that stereos and car DVD players are earthed, but, if they are earthed too long it will cut down the amount of energy going through the system.Again this reduces the performance of the audio and video of the unit.** Poor Connector Choices And Badly Connected Wires **Novice can also make mistakes with their choice of connectors, that is if they use them at all.In fact, if there was one thing that car DVD installation experts wanted DIY fans to learn it would be that twisting two wires just doesn’t cut it. But that’s not all the DIY fan does:# Remove Factory harnesses: If the car has come with a factory-fitted stereo system, chances are it has a custom wire harness as well. Most users usually snip this off and install the one compatible with the DVD player. It is actually better to get a wire-harness adapter for the car DVD that fits the car as it will allow for the old system to be re-installed in future.# Use tape instead of connectors: Most of us having used black tape to hold wires together, while this is good for the short-term and in stable environments it will not work for long durations, as the tape wears off. In a moving environment like a car it is even more dangerous as it could lead to fires.# Wire nuts: These last, but they are bulky and do not always fit properly behind the entertainment system. It is best to go with the right kind of connectors, which an expert would be able to provide.** They Don’t Get The Correct Voltage **It is critical to read the voltage requirement of the entertainment system and to figure out the voltage output of the car. While most systems will play off the box, it is not necessarily the case with older cars and the new entertainment systems.The implications of a botched job can vary from a disgusting looking interiors, poor video and audio quality, damage to the entertainment system, overall damage to the car wiring or more serious the chances of a fire which could endanger the passengers as well as cause serious damage to the car. It is for these reasons that installation is best left to the experts. It can cost as little as USD 45 and take less than half a day to get an expert to do the job.The consequences of an ill-advised DIY attempt can be felt by you the reseller as well. It is always convenient and easy to blame the product for any drop in sound and video quality. Buyers would also be expecting you to give the right installation advice. Ensure the FAQs on your site, clearly state the dangers of self-installation. If this goes against the popular “DIY anthem”, so be it. In the long run, your customers will thank you for being right, not for attempting to be popular.Now you know what not to do, find out one thing to do.

Guidance for the prevention of dropped tools and items when working at height
Guidance for the prevention of dropped tools and items while working at heightFallen tools could cause harm to people, damage to machinery as well as generate costs associated with lost output time. Some typical examples of the effects associated with dropping an object shows the likely-hood of injury or even death from falling objects, relative to the mass and height from which a fall happensA bolt dropped from 23 metres is actually equivalent of being dropped from the 6th floor of a building. The actual velocity attained is 50mph / 80kph on impact. The bolt achieves a mass impact weight of 49.5kgs at this time, resulting in a fatal injury even though hit on the head whilst wearing a hard hat.A screw driver dropped from 14 metres is same as getting dropped from the 4th floor of a building. The velocity attained is 38mph / 61kph on impact. The screw driver achieves a mass impact weight of 73.5kgs at this point, causing a fatal injury even though struck on the head whilst wearing a hard hat.A claw hammer dropped from 6 metres is same as being dropped from the 2nd floor of a building. The speed attained is 24mph / 39kph on impact. The claw hammer achieves a mass impact weight of 117kgs at this time, resulting in a fatal injury even if struck on the head whilst wearing a hard hat.A sledge hammer dropped from 3 metres is equivalent of getting dropped from the 1st floor of a building. The velocity attained is 17mph / 27kph on impact. The sledge hammer achieves a mass impact weight of 147kgs at this point, resulting in a fatal injury even when struck on the head whilst wearing a hard hat.This is a guideline only and in fact even a light-weight item fallen from a considerable height may well turn out to be fatal.Prior to when Work StartsPrior to work being carried out there should be a risk assessment and a method statement which in turn details procedures, specifications for tools, equipment, systems and offers where necessary checklists.People today need to have Know-how, Awareness, Expertise, and also ComplianceDropped ToolsThere’s a serious possibility of fallen items while handling tools at height and a number of these kinds of incidents are becoming reported.Before beginning any type of activity, take into account the chance for dropped tools and objects:Recommendationso Any tools used at height need to be anchored against dropping.o Lanyards, tethers together with connectors must always always be used in between the various tools and belt or bag.o There must be a weakened link or safety provision in between the actual tool and tethering system on the belt or bag.o Wrist straps must only be worn if they offer protection against injury a result of de-gloving.o When there is a need for additional tools, a tool bag / belt with structural anchorage loops should be used.o If the method statement requires it, at all times log tools out and in in the tool register, to ensure that no tools have been left behind.o Put in position barriers below the job area and make sure the extent of the barrier area is appropriate for the work being carried out at height.o Make certain that any grating is safe and make full use of mats as well as short-term covers in places you have got the possibility of small items to fall through gaps.o Wherever a scaffolding platform must be used, make certain toe-boards are fitted.o Continue to know about other activities going on close to as well as under youDropped transportable equipmentA number of recorded occurrences relate to dropped radios, pagers, gas detectors as well as other mobile or portable equipment.Recommendationso All portable devices used at height needs to be secured against dropping.o Carrying pouches should be used for radios and all sorts of other mobile or portable equipment without any dedicated connection point.o The locks for the pouches will have to have a double securing mechanism to safeguard against accidental opening.o Belt clips which enable the radio to become detached when turned 180 degrees should not be used.The likelihood for fallen items during repair and installationWork at height is serious and is particularly shown in a significant amount of reported incidents.Recommendationso All repair along with maintenance work at height needs to be risk assessed.o All components, equipment as well as materials used at height must be anchored against dropping.o Small components should be kept in suitable storage containers or similar.o Once the tasks are finished, a final check needs to be completed, to make sure that no materials or equipment has been left at height.Always keep your worksite tidyRecommendationso Just before work begins, visually examine the work location for loose objects and also debris.Check the actual equipment and also structures within the work area to make certain that any type of fasteners, bolting, covers etc are properly secured.o Tools, equipment along with components must be secured in a secure location at the end of each shift.o Once the work is completed, one last check as well as inventory count must be completed to make sure that absolutely no tools, equipment or materials have been left behind at height.o The actual worksite must be left in a tidy and clean condition, and all tools, equipment and materials must be returned to their designated storage place.Additional ConsiderationsEven if you’re current job isn’t at height, think about the environment where you will carry out the task in addition to any other activities which may be taking place around you.Low-level applications include things like preventing tools from falling in to engines as well as gearboxes, food and pharmaceutical manufacturing lines, underground shafts etc.High-level applications can include construction sites, wind turbines, cranes, buildings, bridges, telecom masts, electric power lines, railway gantries, aircraft hangers, steel structures, buildings, Scaffolding, towers etc.Sectors in which control of tools is critical includesAirline Industries, Aerospace, Automotive, Civil Engineering, Construction, Demolition, Energy,Environment, Factory, Food, Inspection at height, Marine, Nuclear, Mechanical and Electrical,Military, Oil and Gas, Onshore and Offshore, Pharmaceutical, Plant and Machinery,Powered Access, Process and Chemical Plant, Rail, Roof and windows, Shipping, Steel, Telecommunication, Utilities, to identify merely a few.The Leading Edge Safety’s response to these pressing needsOne of the greatest issues working with tools at height applies to conduct, work procedures and inappropriate securing of tools and equipment.Leading Edge has produced a range of tool lanyards, tethers, bags and belts to offer satisfactory securing of tools and equipment while working at height.We have developed professional training courses for those working at height as well as now provide a tool tethering course.For additional guidance on dropped tool legislation and your legal
