Electrical Shock Prevention Methods
What Causes ShockYou touch electrical parts and that is when the current flows through your body. This is when the injury can start and it usually happens above 30 milliamps. If it goes above 75 milliamps the risk of something bad happening increases.
Basic Protection Rules
You need to be in control of the source of the electricity. You have to make sure your body is isolated from the current.. You have to break the path of the fault.1. Proper Insulation
You keep the conductors covered so they do not touch anything they should not.Actions:
* Use cables that have insulation
* Replace the insulation if it gets damaged and do it fast
* Use tools that are insulated
Example:
If there is a wire that is not covered it ,can increase the risk of getting a shock by 100 percent.
2.. Grounding
You connect the equipment to the earth so the current can flow to the ground if something goes wrong.Actions:
* Connect all the metal parts together
* Test how well the earth is conducting the current
* Make sure the value is below 5 ohms for systems
Result:
If something goes wrong the current will flow to the ground instead of through your body.
3. Use of RCD
You install a current device in the circuits.Key data:
* It trips at 30 milliamps
* It responds in than 0.03 seconds
Result:
The power will cut off before you can get seriously hurt.
4. Isolation of Supply
You disconnect the power before you start working.Actions:
* Switch off the power supply
* Use a lockout tagout
* Check that the voltage is zero
5. Personal Protective Equipment
You protect your body from the current.Use:
* Insulated gloves
* Safety shoes
* Rubber mats
Example:
The rubber can reduce the flow of the current.
6. Safe Working Distance
You stay away from the electrical parts.Typical clearance:
* For voltage stay at least 1 meter away
* For voltage follow the standard limits
7. Warning Signs and Barriers
You control who can access the area.Actions:
* Install signs that say danger
* Use barricades
* Only let trained staff enter the area
8. Regular Inspection
You check the condition of the system.Actions:
* Inspect the cables every week
* Test the breakers and the residual current device every month
* Replace any equipment that's faulty
9. Dry Working Conditions
You avoid working in conditions.Rules:
* Keep your hands dry
* Do not work on floors
* Use equipment that is
Fact:
If your skin is wet it can reduce the resistance by, up to 90 percent.
10.. Awareness
You train the workers on what to do.Focus:
* Identifying the hazards
* Responding to emergencies
* Using tools safely
Emergency Response
If someone gets a shock:* Do not touch the person directly
* Switch off the power
* Use an object to separate the person from the electrical source
* Call the emergency service
* Start CPR if it is needed
Field Checklist
Check the insulation conditionVerify the earthing
Test the current device
Use personal protective equipment
Keep the area dry
You follow these steps and you can reduce the risk of getting a shock. You can protect peoples lives. Electrical shock prevention methods are important. You need to follow these shock prevention methods to stay safe.
