Final answer:
To prevent static charge on an extinguisher, it should be grounded using a copper wire. This allows any built-up static electricity to safely discharge to the ground.
Step-by-step explanation:
The correct answer is option b) Ground it using a copper wire. To prevent a static charge on an extinguisher, you need to ensure that any static electricity that builds up can be safely discharged. Painting it with non-conductive paint would prevent electricity from flowing, thus it would not dissipate any static charge.
Regularly shaking the extinguisher has no effect on static charge accumulation. The most effective method is to ground the extinguisher so that any static charge can flow to the ground.
Grounding is typically done using a conductive material, such as a copper wire, which is firmly connected to both the extinguisher and a ground point, such as a metal stake driven into the ground or the electrical grounding system of a building.
The correct answer is option B) Ground it using a copper wire. Grounding an extinguisher is an effective way to prevent static charge build-up. When an extinguisher is grounded, any static charge that accumulates on its surface will be dissipated through the copper wire and into the ground. This helps to prevent any potential discharge of static electricity, which could be dangerous.
In everyday life, grounding is commonly used to prevent static electricity from accumulating on objects. For example, many electronic devices are grounded to protect them from damage caused by static discharge.
