What is the golden rule of safety?
It is necessary to identify danger and to assess risks prior to start of any activity. With every change of process, person or natural circumstance the danger and risks must be re-assessed. Each person must be trained, prepared and able to carry out his duties.
What are the safety precautions in using electricity?
Top 10 rules for electric safety
- DON’T plug a bunch of stuff into one outlet or extension cord.
- DO make sure all electric cords are tucked out of the way.
- DON’T ever play near or on a green transformer box or climb the fence around an electrical substation.
- DON’T yank an electrical cord from the wall.
What is the most common electrical injury?
Electrical burns are the most common shock-related, nonfatal injury. They occur when a worker contacts energized electrical wiring or equipment. Although electrical burns can occur anywhere on the body, they most often occur on the hands and feet.
How do I get rid of static electricity in my body?
Stop Being Zapped: Skin Tips
- Stay Moisturized. Keeping your skin hydrated is one way to reduce the effects of static shock.
- Wear Low-Static Fabrics & Shoes. Rubber-soled shoes are insulators and build up static on your body.
- Add Baking Soda to Your Laundry.
What are some examples of static charge?
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons. The electrons cling to your body until they can be released. As you reach and touch your furry friend, you get a shock.
Why do we feel the current when we touch something?
When you touch a doorknob (or something else made of metal), which has a positive charge with few electrons, the extra electrons want to jump from you to the knob. That tiny shock you feel is a result of the quick movement of these electrons.
Why do I keep getting electric shocks?
Heating warms the air and reduces its humidity. Static shocks are often noticed in cold dry weather, especially when in a centrally heated environment, and may disappear when the weather gets more humid. Static shocks may also be encouraged by air conditioning in hot weather.
Why do I keep getting shocked by metal?
If you carry a metal object like a coin, key or paper clip around with you, and touch it to something metal in your house, any electrons stuck to your body will flow through the metal and away, preventing the “jumping” effect that causes a shock.
What is the effect of electric shock on human body?
A shock can affect the nervous system When nerves are affected by an electric shock, the consequences include pain, tingling, numbness, weakness or difficulty moving a limb. These effects may clear up with time or be permanent. Electric injury can also affect the central nervous system.
How does static electricity affect humans?
According to the current knowledge, static EF can cause effects on the body via changes in the distribution of electric charges on the surface of the body. A sufficiently large surface charge density may be perceived through its interaction with body hair and by other effects such as spark discharges (micro-shocks).
What happens when something becomes positively charged?
An electrical charge is created when electrons are transferred to or removed from an object. Because electrons have a negative charge, when they are added to an object, it becomes negatively charged. When electrons are removed from an object, it becomes positively charged.
