---|---|---|---|
2016 | 47,700 | 1,250 | 440 |
2017 | 48,000 | 1,350 | 475 |
Electric Shock Risks
When hot and neutral wires touch, not only can it create a short circuit, but it can also pose a serious risk of electric shock. If an individual comes into contact with exposed wires or faulty connections, the consequences can be grave. Electric shock can lead to various symptoms ranging from mild discomfort to severe injuries and even death.
Factors Affecting Severity of Electric Shock
The severity of an electric shock depends on several factors:
- Current Intensity: Generally, the higher the current flowing through the body, the more severe the shock.
- Pathway through the Body: The path the electric current takes can influence the outcome. For example, if the current travels through the heart, the risk of fatality is significantly higher.
- Duration of Contact: The longer the exposure to electrical current, the greater the potential damage.
Preventive Measures to Take
Given the risks associated with hot and neutral wire contact, it’s essential to take preventive measures to avoid dangerous situations.
