Hand Tool Hazards and Protection Usually, hand and power tool hazards are caused through misuse and improper maintenance. You should remember the following when handling such tools: Do not use wrenches when their jaws are sprung; Never use impact tools, such as chisels and wedges, when their heads have mushroomed; Tools with loose, cracked or splintered handles should never be used You must never use a screwdriver as a chisel; Tools with taped handles should be checked first for any hidden cracks; Use Personal Protective Equipment, such as safety goggles and gloves; Keep floor surface where working free from debris and tripping or slipping hazards; Keep cutting tools sharp. Power Tool Hazards and Precautions Power tools could be extremely hazardous when used improperly. They must always be fitted with guards and safety switches. Here are some precautions you should take while handling such tools: Remember to disconnect all tools when they are not in use and also when their accessories are changed; Before servicing and cleaning all tools must be disconnected from the power source; People that are not involved with the work must be kept away from the work; Never hold the switch button while carrying a plugged-in tool; Before starting to work, make sure both your hands are free to operate the tool. You can do this by securing your work with clamps or a vice; Do not wear loose clothing and jewelry that can get caught in moving parts; Damaged electric tools must be removed and tagged with the words: ?Do Not Use?; Portable tools should never be carried by their cord; Electric cords must not be used to hoist or lower tools; All cords and hoses must be kept away from oil, heat and sharp edges at all times. Remember, it can only take one mistake! So be sensible and stay safe. Common Mistakes When Building Network Cables Dustin Twiggs When building network cables people often get confused about what's important. It's not hard to see why though. With the money spent in marketing the cable industry most manufacturers want you to think that one particular quality or another that they feature is more important than something else. It's just not true though. Chances are, 90% of the cable manufacturers you are able to buy from are going to be within 5-10% of each other quality wise. So what's really important? Well first off something you should know about CAT5 network cable vs CAT 6. CAT 6 is capable of transmitting data much faster. However, unless you are using the correct components, you will spend extra money on cable and then receive no added benifit! Your connectors for instance... What good is spending all that extra money on nice cable if you are going to bring down it's quality by using cheap connectors? 2nd, pinout. Just straight through won't cut it. There is a particular network cable pinout and the conductors are twisted in pairs to maximize overall quality. Get it right! 3rd, the strain relief. When you crimp the RJ-45, make sure you crimp the pvc (or plenum) jacket of the cat5 or cat6 that you are using. Some folks will strip the jacket to far back and crimp the RJ45 to only the individual conductors which will provide you no strain relief. the cable is much more likely to fall apart with this type of construction. 4th, use a quality crimp tool. Poor quality crimp tools can quickly become damaged and the teeth used for actually crimping the gold contacts can come off center and cause the crimp to miss contact with the conductors. If this happens that it will likely not be fixable and you will have to cut off the connector and try again. For more info on computer cables be sure to visit our homepage.
