In this tutorial, we are going to learn about Best tutorial on how to Safe Electrical Devices.
- Electrical safety is a critical when working around electrical equipment, electronic components, batteries or wiring. A very small levels of voltage, as low as 35 volts can be fatal. Think of voltage as the speed of a bullet and current as the size of the bullet. Even a small bullet can harm you if it travels at great speeds. Alternatively, a large bullet travelling at slow speed can also be fatal or cause a great deal of physical harm. Another way to look at safety would be to be run over slowly by a large truck, the pressure is low but the weight of the truck is high, this can be deadly. All of these events would be avoided by most same and reasonable people.
- When you receive an electrical shock, the pressure you feel is the voltage, damage is done to human tissue by the particles of electrical current that runs through unprotected human cells. This can include burns, deep holes, loss of body parts and scarring. In additional, the voltage pressure will cause muscles to contract and can propel you into other object or dangers, or cause disruptions in organ run from electrical impulses, electrical safety is critical if you work around this dangerous thing called electricity.
The dangers of an electrical shock can include the following:
- Damage to human tissue.
- Removal of limbs or critical body parts.
- Changes in human electrical responses that include brain damage, nerves damage, or heart damage.
- Further injury from being physical thrown into other dangers or objects.
- Temporary or lifelong nerve damage, mental disability, or heart damage.
From this list please see the value of working safety around electricity. In additional to dangers to yourself, you can cause damage to the electrical devices you handle in your job. Stored charge within your body can discharge into electrical devices and damage the device. This damage may occur at the time of the discharge or later after the device has been in use for a period of time.
Workplace safety procedures are a critical element of employment. Follow all safety procedures for your protection and protection of the manufactured product. Safe interactions during repair, manufacture and handling, or maintenance of equipment and devices are critical job functions.
General safe practices
- Grounding – Electrical circuits have a high voltage wires called the hot wires and a grounding side that connects to the neutral wire, the neutral wire is the return side to the circuit‘s power source.
- You must remain isolated from the power source. Never come in contact with an energized power line, this include both the hot side of a critical and neutral side, in some circuits, multiple ground exist, some at elevated voltages. The level of current that flows will be dependent on how much resistance exists between the source of the voltage and ground. For example if you are standing in water and come in contact with a power source the resistance to ground will be very low. If you were standing on a made up if insulation mater, your resistance to ground could be high, thus limiting the current that would be flow.
- Another factor to keep in mind when you are in the area of energized circuit is the path of grounding if you should receive a shock. Holding one hand on a steel pipe connected to ground and standing on mat of insulation material will provide little protection. The path for current flow you have created is from one hand through your heart. If you receive an electrical shock, it will travel your body between the voltage sources to ground.
Safe Workplace Tools-
When working around open energized equipment or power source, avoid grounding yourself. Avoid any grounding of body part is that would allow a follow of current through internal organs should you receive a shock. Placing insulated mats around where you work is a good practice to prevent grounding of arms, your back, or head.
Step forward protection –
- Always work on insulation material, normally rubber floor mats designed for this purpose.
- Do not wear jewelry including rings on fingers or other body parts.
- Use electrical insulated tools in good condition.
- If you must comes into contact with conductive surfaces – try to drape the insulation mat over the contact points to avoid direct avoid.
- Clear water away from all work areas as well as clutter or other trip hazards.
- Use proper ladders designed for electrical work area.
- Always check cord conditions and work area prior to the start of work.
- Be aware of your environment and others around you at all times while working in and around electrical equipments.
How to prevent static electricity damage to equipment and board components?
An important safety considerations within the workplace is handling equipment, circuit assembles and electronic components. Many subs – assembly parts and circuit board can be damaged by static electricity in our bodies or in environment. The damage may destroy or even weaken parts what will fail at a later time. There are static safe plastic bags, static free foam, and static free work mats, ankle and wrist straps to help ensure safe transportation and handling of static sensitive parts. One time damage is one time too much. When handling these parts it is essential that you use static controls. To remove static safety from your body, you connect yourself to ground through a wrist or ankle strap and special connecting cord to ground. It is essential for your safety that you use the special cord that comes with the wrist or ankle strap. The resistance of the cord is high enough to prevent a dangerous level of current to flow to ground while not allowing static electricity to build up in your body. This protects the components from static damage while protecting the worker from current levels travelling to ground if they receive a shock. Never connect the wrist strap directly to ground without the proper cord that is too be used within mat.
Best Tips for Electrical Safety –
- Protect yourself from electrical shock.
- Protect the equipment and components from static damage.
- The practical that flow down electrical circuit is electrical current. The push of this current is the voltage. Voltage can cause current to travel through this air if the voltage is high enough. Current hurt or even kill at fairly small levels. When working with circuits, it is important to follow workplace federal, state and local safety regulations. Most areas requires locked out a circuit, recheck the area and circuit to be energized. Even through you have locked out a circuit, re-check the area and circuit if you have been away from the area of control. Don’t return from a lunch break and assume no one has tampered with your safety devices.
- No level of electrical shock is acceptable – every circuit is capable of harm to you or devices. Know your risk and take appropriate precautions. In the real work, world are faced with risk so we have procedures to minimize the events that could cause us harm. Follow preventive measures and the life you save may be your own.
