How To Install A Wall Safe

Locate the wall studs with a stud sensor or hammer and nail. Then, use a level to draw a 14¼-inch square onto the wall between the two studs. Cut out the opening with a drywall saw; work carefully to make sure you don't cut into electrical wiring. (If you find some, you'll have to push it aside or reroute it.)

The left and right edges of the cutout will extend ¼-inch beyond the studs on each side of the opening. Fill in these spaces with wood shims or strips of ¼-inch plywood to build the studs out flush with the edges of the opening. Secure the wood with finishing nails.

With its door open, tilt the safe into the opening and press it flush against the wall.

Fasten the safe to the studs with the four screws provided. Install the two removable steel shelves, if desired. Note that you’ll need both the three-digit combination and the key to open the safe.

Lighting Control Sensor

A lighting control sensor has an integrated light-sensitive element, which changes characteristics depending on the strength of the light.Sensors are a very important element of a lighting control system, as they are the components that register a signal and convert it into a control signal, thus activating the system.

There are many kinds of sensors to choose from, and you must therefore make sure that the sensor you choose satisfies your requirements and needs. Some types can be used inside and outside, while other types should be used indoors.

Lighting control systems are employed to maximize the energy savings from the lighting system, satisfy building codes, or comply with green building and energy conservation programs. Lighting control systems are often referred to under the term Smart Lighting.

Polymer Insulator Resists Thousands of Volts

Polymer insulators are made from resins, a relatively uncommon material for insulator compared with porcelain. With high electrical resistance, it can moderate the voltage for stable operation. Polymer insulator being a common product applied in electronic device, it can moderate the voltage for stable operation with high electrical resistance.

 

An electrical insulator is a material whose internal electric charges do not flow freely, and which therefore does not conduct an electric current, under the influence of an electric field. A perfect insulator does not exist, but some materials such as glass, paper and Teflon, which have high resistivity, are very good electrical insulators. A much larger class of materials, even though they may have lower bulk resistivity, are still good enough to insulate electrical wiring and cables. Examples include rubber-like polymers and most plastics. Such materials can serve as practical and safe insulators for low to moderate voltages (hundreds, or even thousands, of volts).

How Delta Arrestor protects you from high voltage surge

A lightning arrestor (delta arrestor) helps to provide immediate and reliable protection against the high voltage surge (such as that of a lightning strike) on your building or power lines. These units last for a lifetime, except in the extreme cases of rare excess surges. This particular type of surge is particularly devastating to electrical components, almost always rendering them useless. In addition, if you are not protected against high voltage surges, an electrical fire can easily be started within moments as a result of high current levels rushing through building wires.

 

Your breaker box is incapable of providing protection against this “lightning fast” surge of electricity. By the time your breaker has switched off, the surge has literally already done its damage. Note that although a lightning arrestor helps to prevent high voltage spikes from infiltrating your circuits, it does not protect against the common smaller surges.

Remove Decking Screw Easily and Safely

 

Stubborn screws are always a problem whenever you want to replace or repair decking. In fact, you can still remove decking screw easily by follow the instruction which teach you how to finish the work without damaging your decking.

 

Tools included drill-driver, screw extractor set, bit set, tap wrench and reciprocating saw (extreme scenario) are essential to prevent you to get hurt and decking to be destroy. Also, depending on different situations, you might need to take various methods to remove decking screw.

 

For standard removal, place bit in drill-driver that corresponds to screw you wish to remove. Make sure that bit is secure and that drill-driver is set to reverse drive.

Secondly, insert bit into screw head and hold firmly. If enough pressure is not used, the teeth of the screw head may strip. At last, hold down drill-driver trigger until screw is completely extracted from boards.

 

For stripped screws, you need to extract the screw by a normal bit (Phillips are the most commely). Make sure your drill-driver is set for reverse drive. While, if it is useless, insert a drill bit that corresponds to the size of screws you are removing. You can check this by taking the bit and placing it in line with the screw head. The bit has to be smaller than the shaft of the screw. Drill a hole in the broken screw. After that, attach the proper extractor (sets come with a chart that cross-references screw sizes with stamped extractor size) to your tap wrench and insert it into the hole. Turn counterclockwise. The extractor acts in the same way as a wine corkscrew might: gripping the sides of the hole you have made. As you turn, the broken pieces of screw should unthread themselves, leaving the original threaded hole undamaged.

 

However, if it still doesn’t work which means you need to take it as an extreme scenarios.

1. If wood needs to be replaced, cut away board around troublesome screws with a reciprocating saw.

2. Insert a metal-cutting blade into the reciprocating saw and make sure it is secure.

3. Saw off remaining screw posts so that they are level with the beam they are secured in.

Protect the Safety of Your Kids by Personal GPS Tracker!

       It’s good for taking your kids outside for picnic or entertaining. Also, it’s good for letting them playing with other kids in the neighborhood. However, what every parents concern is the safety issue. “How do I make sure that I can always keep an eye on them?” “How can I stop worrying about the possibilities that my kids may lost outside?” This truly matters a lot. Nowadays, hundreds of thousands of children are reported missing every year. The vast majority of them are recovered quickly, but many parents greatly fear discovering that their child is missing. As technology advances, parents are taking greater measures to know where their children are at any given time. One of the resources available is a child tracking device, the so-called personal tracker. Some of these devices use a global positioning system (GPS) to ascertain a child’s location from long distance, and others use radio frequency for nearby locations.

       GPS personal tracking devices assist in the care of the elderly and vulnerable. Devices allow users to call for assistance and optionally allow designated caregivers to locate the user's position, typically within 5 to 10 metres. Their use helps promote independent living and social inclusion for the elderly. Devices often incorporate either 1-way or 2-way voice communication which is activated by pressing a button or sliding a switch. Some devices also allow the user to call several phone numbers using pre-programmed speed dial buttons. Trials using GPS personal tracking devices are also underway in several countries for use with early stage dementia.

How to Prevent Sport Injury?

       Sports injury is injury that occur in athletic activities. In many cases, these types of injuries are often due to overuse or acute trauma of a part of the body when participating in a certain activity. For example, runner's knee is a painful condition generally associated with running, while tennis elbow is a form of repetitive stress injury at the elbow. Other types of injuries can be caused by a hard contact with something. This can often cause a broken bone or torn ligament or tendon. In fact, the best way to deal with sports injuries is to prevent them. Prevention includes knowing the rules of the game you're playing, using the proper equipment, and far infrared heating pads.

       If unfortunately, even though you play safely, you still get hurt. There are several tips and ways for healing it. Sports injury can be treated and managed by using the principle “P.R.I.C.E.S,” which stands for protect, rest, ice, compression, elevation, and stabilize. The primary inflammatory stage typically lasts around 5 days and all treatment during this time is designed to address the cardinal signs of inflammation – pain, swelling, redness, heat and a loss of function. During this period of time, it’s good to adopt hot and cold therapy, using far infrared heat wraps alternately. This can heal your pain effectively.

The Safety Issue About Ultrasonic Machine

       Ultrasonic machining, also known as ultrasonic impact grinding, is a machining operation in which a vibrating tool oscillating at ultrasonic frequencies. Aided by an abrasive slurry that flows freely between the workpiece, this vibrating tool is used to remove material from the workpiece and the tool. It differs from most other machining operations because very little heat is produced. The tool never contacts the workpiece; as a result, the grinding pressure is rarely more than 2 pounds, making this operation perfect for machining extremely hard and brittle materials, such as glass, sapphire, ruby, diamond, and ceramics.

       Like most industrial equipment, ultrasonic machine poses the risk of some hazards. These include exposure to high heat levels and voltages. This equipment should always be operated using the safety guidelines provided by the manufacturer in order to avoid injury. For instance, operators must never place hands or arms near the welding tip when the machine is activated. Also, operators should be provided with hearing protection and safety glasses. Operators should be informed of the OSHA regulations for the ultrasonic welding equipment and these regulations should be enforced. Therefore, ultrasonic welding machines must receive routine maintenance and inspection. Panel doors, housing covers and protective guards may need to be removed for maintenance. This should be done when the power to the equipment is off and only by the professional operator of this machine.

The Safety and Health Topics for Pressure Vessel

       A pressure vessel is a closed container designed to hold gases or liquids at a pressure substantially different from the ambient pressure. The pressure differential is dangerous and many fatal accidents have occurred in the history of pressure vessel development and operation. Consequently, pressure vessel design, manufacture, and operation are regulated by engineering authorities backed by legislation. For these reasons, the definition of a pressure vessel varies from country to country, but involves parameters such as maximum safe operating pressure and temperature.

       Recent inspections of pressure vessel have shown that there are a considerable number of cracked and damaged vessels in workplaces. Cracked and damaged vessels can result in leakage or rupture failures. Potential health and safety hazards of leaking vessels include poisonings, suffocations, fires, and explosion hazards. Rupture failures can be much more catastrophic and can cause considerable damage to life and property. The safe design, installation, operation, and maintenance of pressure vessels in accordance with the appropriate codes and standards are essential to worker safety and health.

Safe and Airtight Solenoid Valves Can Prevent Liquid of Gas Leakage

       Flow control equipment is not only for industrial use, it also serves functions in buildings and domestic use. The difference is usually seen in the size and complexity of the valve monitor and the stainless steel solenoid valve. Stringent specifications are applied for hazardous factory environments. The key objectives that the stainless steel solenoid valve achieves are safety and automation. Safety and efficiency are extremely important in public utility industries like water treatment plants, power plants and refineries. Different valves move at different angles and distances called travel. Each valve type has a specific actuator. Due to its function in fluid control, a stainless steel solenoid valve must be precision machined to be airtight.

       There are various types of actuators. They are either hydraulic or pneumatic depending on the scale and pressure of the system. A valve limit switch can be specified to be explosion proof, which is called explosion proof solenoid valve. The parts of the valve monitor like the stainless steel enclosure and attachments are standardized. ISO 5211is the European standard that has also been declared as a national standard by several countries. It defines the part turn actuators, including description of keys like square and flat drives.

       The benefits of ISO standardization are; inter-compatible attachments, immersion in water, anti corrosion, flame proof and explosion proof. The standard protects the purchaser. It also facilitates the trade of the manufacturer by quality certification. A valve monitor may incorporate safety features to prevent overloading. This enables the stainless steel solenoid valve to trip when torque limit is exceeded. Another safety function is in thermostat to guard against overheating of the motor. Once again the valve monitor will trip and there will be no feedback signal. The valve monitor controls the flow rate with a modern self adapting position.
