Why We Need More Safety Switches in Our 皇冠APP下注s
安全开关拯救生命. There’s no disputing that fact, and over the past 25 years more and more homes have been fitted with these miraculous devices. 这是好消息!
然而，不太好的消息是 that only around 65% of homes have 安全开关 installed today. 其中, almost none have 安全开关 fitted on all their circuits, with 29% only on power outlet circuits and 39% on power and light circuits. 虽然这是一个 great start to thinking more safely, an electrical fault could still occur on any circuit including the lighting, power outlets, hot water, oven, stove, and 空调. For full protection, most homes would need to have at least 安装四个安全开关.
调查显示，大多数 people believe they are well protected from electrical injury at home, but this isn’t the case when 65% of homes aren’t fully protected by the 安全开关 他们已经安装了. This indicates that our wires have crossed somewhat, and we need to switch our thinking about electrical safety and safety 开关.
安全开关或残余 Current Device (RCD) is a device that’s designed to cut power to an electrical circuit in a fraction of a second in the event of an electrical leakage (0.03 准确地说是秒). The moment a circuit is detected to be leaking (as would be the case if someone touched a bare wire), the flow of electricity would be 心跳停止了. The electrical flow is stopped so fast that the person doesn’t even have time to receive a shock, and that’s why safety 开关 are so important when it comes to electrical safety!
你可以认出一个安全开关 by the button marked ‘test’ on the front, which is what helps to distinguish it from a circuit breaker, which look similar. 许多家庭都有断路器 installed, but these only protect against overloading and short circuits. 这是 a good start, but not enough to protect someone from electrocution.
主要有四种类型 安全开关: •Meter 箱安装 – These are mounted next to circuit breakers in the meter box or distribution 板, •结合 安全开关和断路器 -这些可以防止电 shocks as well as protecting electrical circuits and appliances, and are a popular option for existing meter boxes with limited space, •可移植的 安全开关 – These can be attached to a power board or extension lead to protect the appliances that are connected to them (i.e. 在户外使用电动工具 where they aren’t protected by a meter box safety switch), and •权力 点安全开关 – These are fitted to power points and are ideal for protecting appliances in 比如浴室或车间. •
皇冠APP下注不想诉诸于恐吓 tactics, but to highlight the importance of 安全开关 we’ve got some 证明其必要性的统计数字: •15 people are killed in homes every year in preventable electrical accidents where 未安装安全开关 •300 people are hospitalized every year with serious electrical injuries and burns.
可以有很多不同的 causes of electrical accidents, from a child putting a knife in a toaster to a handyman drilling through a live wire inside a wall. 它也可以来自a frayed cord, damaged plug, or faulty appliance. 电在皇冠APP下注周围无处不在 the home, and all it takes is one small slip for it to become our enemy instead 皇冠APP下注的朋友.
政府法规 安全开关 mandatory in new homes in every state, but this only applies to 电源插座和照明电路. Legislation on existing homes varies from state to state and doesn’t require 安全开关 on all household circuits.
这也是原因之一 somewhat relaxed regulations is cost, but the bottom line is what price is a 人类生命的价值? Airbags and seatbelts were expensive when they first became introduced as mandatory in cars, but they’ve since saved countless lives 在过去的几年里. Their cost has been largely absorbed into new car prices, and the same will be the case for 安全开关.
We’re not talking about huge expenses here, either. It would only cost around $300 to install four 安全开关 in the average new home, which is not much when you consider the benefits they provide! Many people would be resistant to forking out money for extra safety, 然而, and that’s why we need to switch our thinking and maybe introduce 安全开关 in stages. 这可以通过:
•Targeting investment properties and home sales first, •Subsidizing installation as with solar power,
•Providing compensation for low income earners, and
•Providing a phase-in period that allows homeowners to plan for the cost of retrofitting.
Safety 开关 should be in every household to ensure the complete safety of its inhabitants, and when we’re talking about the value of a human life, 这是无法用金钱衡量的. Perhaps it’s time we all switched our thinking to the long-term benefits provided by 安全开关 and started taking advantage of the incredible protection this amazing technology offers.
