Always dry your hands! Dry skin is a fairly good insulator, getting them wet turns you into a giant short circuit just waiting to happen.

If your hands are wet when you touch a charged object, you will get an electric shock or electrocuted. Yes but, wet with what? Wet your hands, with water. Because you will get shocked and possibly DIE!! Driving on smooth wet surfaces is dangerous. Log in. Spark Plugs and Wires. Ford Explorer Sport. Home Electricity. Study now. See Answer. Best Answer.

Summertime in the Southern Hemisphere coincides with the festive season and end-of-year travels. It is well-known for long drives to our beautiful beaches as well as inland journeys to various nature reserves and game farms. It is a season we wish to celebrate with family and friends but also sadly a.

Large quantities of freight are transported on our roads daily. To share roads safely and responsibly with other road users there is an onus on the operator to ensure that these loads are safely secured during transport.
But what are the Rules of the Road on Securing loads during transport, what do. South Africa is well known for a rich history in mining and the export of mineral resources.
With the 10th largest road network in the world and a heavy reliance on road freight transport, it is to be expected that motorists often share the roads with the transporters of dangerous goods. Are we. The Arrive Alive website supports those individuals and institutions who take the initiative to arrange road safety conferences in South Africa.
We believe that this contributes to greater awareness of road safety and could assist in planning effective road safety strategies. The website www. The Department of Transport has revealed in a Green Paper that annual road deaths in SA are at a shocking 15, lives lost. These numbers do. Load More Pages. In our homes breakages and excessive wear and tear on electrical equipment can occur frequently so we need regular inspections and take precautions to ensure safety.
If an appliance repeatedly blows a fuse, trips a circuit breaker or gives you an electrical shock, immediately unplug, repair or replace it. What do we need to inspect? Correct labelling when needed eg. Electricity requirements Loose Fixtures or fittings It is also important that we test our equipment regularly - switch it on and off and look for possible problems or faulty connections.
The following tips are for you to use when buying and using plugs. Do not overload plugs - rather use an adaptor. How do we minimise the potential safety dangers caused by electrical cords? Use SABS approved electrical wires or cords. Do not use frayed cords - Do not join cords with tape! Replace worn and frayed cords on appliances immediately. Keep cords well away from hot stoves and other hot surfaces. Avoid running extension cords across doorways or under carpets and rugs.
Make sure that cords are not placed in areas with high traffic where people may trip over them. Do not let cords rest on furniture but rather let them run along walls and around furniture. Do not run cords through hinges or nail them to walls, floors or any other objects.
Extension cords should be used on a temporary basis only. It is dangerous to handle the plug with wet hands. Doing this may result in receiving an electric shock. Unplug the power cord from the wall outlet before you move the machine. While moving the machine, you should take care that the power cord will not be damaged under the machine.
The severity and effects of an electrical shock depend on a number of factors, such as the pathway through the body, the amount of current, the length of time of the exposure, and whether the skin is wet or dry.
Water is a great conductor of electricity, allowing current to flow more easily in wet conditions and through wet skin.
The effect of the shock may range from a slight tingle to severe burns to cardiac arrest. Table While reading this chart, keep in mind that most electrical circuits can provide, under normal conditions, up to 20, milliamperes of current flow.
In addition to the electrical shock hazards, sparks from electrical equipment can serve as an ignition source for flammable or explosive vapors or combustible materials. Loss of electrical power can create hazardous situations. Flammable or toxic vapors may be released as a chemical warms when a refrigerator or freezer fails. Fume hoods may cease to operate, allowing vapors to be released into the laboratory.
If magnetic or mechanical stirrers fail to operate, safe mixing of reagents may be compromised. Electric shock is another hazard common to many pieces of laboratory equipment.
Any electrically powered item of laboratory equipment which is subject to spillage of chemicals or water, or exhibit signs of excessive wear should be used carefully. Electrical shocks occur when the electrical circuit completed by the part of human body.
One way this can occur is by contacting a metallic part of a piece of equipment that has become energized by contact with an electrical conductor. The severity of the electrical shock depends on the following:. A victim of electrical shock could be knocked unconscious.
If the victim is still in contact with the live power source, turn off the live source or press the emergency power cut off button before administering aid.
Do not touch anyone that is still in contact with a live power source, as you could be electrocuted as well. Even if an individual survives a shock episode, there may be immediate and long-term harm on tissue, nerves, and muscle due to heat generated by the current flowing through the body. The heat generated is basically resistive heating such as would be generated in heating coils in a small space heater.
The scope of the effects of external electrical burns is usually immediately apparent, but the total effect of internal burns may become manifest later on by losses of important body functions due to the destruction of critical internal organs, including portions of the nervous system, which is especially vulnerable.
Induction motors should be used in most laboratory applications instead of series-wound electric motors, which generate sparks from the contacts of the carbon brushes.
