Is There a Risk of Electric Shock in Container Houses?
If the electricity usage in container houses is not standardized or the houses are not properly grounded, there is a risk of electric shock; if the electricity usage is standardized and the houses are properly grounded, the possibility of electric shock can be effectively reduced. Here is a detailed analysis:
Improper electricity usage can easily cause electric shocks
Container houses are mostly connected as a whole with steel components. When users install electrical lighting equipment, if the wires are directly tied to the steel components without setting up wire conduits or wire trough isolation devices, once the wire insulation layer is damaged, the steel components will become electrified, and electric shock accidents are very likely to occur when people come into contact with them. In addition, some containers have the situations of unauthorized wire connections and mixed use of high-power electrical appliances, which will increase the circuit load, cause the wires to heat up and even catch fire, and also increase the risk of electric shock. For example, electric shock accidents caused by improper electricity usage frequently occur in some residential containers at construction sites.
Poor grounding increases the probability of electric shock
In thunderstorm weather, if container houses are not properly grounded, the metal box body, with strong electrical conductivity, is prone to attract lightning. The lightning current may be conducted to the interior through the box body, endangering the safety of personnel. Moreover, when the insulation of electrical equipment is damaged and the outer shell becomes electrified, without proper grounding, when people come into contact with the electrified outer shell, the current will flow into the ground through the human body, causing electric shock.
Standardized electricity usage and proper grounding can reduce risks
If container houses use electricity in a standardized manner, set up isolation devices when installing power lines, do not place circuit cables directly on the surface of steel components, and ensure that the houses are properly grounded, the risk of electric shock can be effectively reduced. After grounding, when the outer shell of electrical equipment becomes electrified or encounters lightning, the current will preferentially flow into the ground through the grounding wire. Since the resistance of the grounding wire is much smaller than that of the human body, the possibility of electric shock to personnel is greatly reduced. For example, according to Michael Faraday's theory, when a closed metal space encounters a thunderstorm, the electric charges shot towards the closed metal container will flow evenly around it instead of passing through the container. Therefore, container houses that are properly grounded are relatively safe in thunderstorm weather.
