Know the Dangers in Your Older Home
In Malaysia, faulty electrical sources are listed on the top list as cause of homes fires. Like a robbery in the middle night, fire can rob one’s life and property in the blink of eye.
The most tragedy home fire cases is at Darul Quran Ittifaqiyah tahfiz in Kampung Datuk Keramat, Kuala Lumpur that caused 23 people dead and mostly of them are children. Therefore, inspection of fire safety is a must especially when your home is older.
This is because people tend to forget that everyone is potential to be a fire victim and every home has a fire hazard. Implementing fire safety measures including prevention, early detection and control can preventing losses in a long way.
Actually older homes pose an even greater threat as dependence on electricity is increasing.
But as the home are built before many of the electronics and appliances were even invented, the increased demands for energy can be overburden an older home’s electrical system causing fires or electrocutions.
Thus, by using more up-to-date technology and by recognizing warning signs your home may be showing can prevent many electrocutions and home electrical fires. First, you need to educate yourself on the dangers commonly found in home so that you can take an active role in protecting yourself.
Arc Fault Circuit Interrupters (AFCIs)
Figure 1 Arc Fault Circuit Interrupters (AFCIs)
What is arc fault? An arc fault is a high power discharge of electricity between two or more conductors.
This discharge translates into heat, which can break down the wire’s insulation and possibly trigger an electrical fire. In facts, electrical arcing is one the source ignition in more than number of fires annually.
The causes of arc faults are:
- Loose or improper connections, such as electrical wires to outlets or switches, overheated wires and cords
- Damaged electrical appliances
- Cracked wire insulation stemming from age, heat, corrosion, or bending stress
- Electrical wire insulation chewed by rodents
- Frayed appliance or extension cords
- Pinched or pierced wire insulation, such as a wire inside a wall nipped by a nail or a chair leg sitting on an extension cord
How can Arc Faults be prevented in older homes?
We can use Arc Fault Circuit Interrupters (AFCIs). It is a devices that replace standard circuit breakers in the electrical service panel. This devices can detect arc faults and shut down power to a circuit in milliseconds.
Lack of AFCIs among the primary residential hazards can be associated with burns and fire-related injuries. Thus, it is important to have an AFCI breaker installed in home because an AFCI provides a higher level of protection than a standard circuit breaker.
It works by detecting and removing the hazardous arcing condition before it becomes a fire hazard. Hidden electrical fires can spread quickly, delaying detection by smoke alarms.
A report revealed that number of factors that contribute to electrical fires in existing homes, including improper alterations, deterioration due to aging, and faulty products. These factors often cause arc faults, which are a leading cause of home fires.
Figure 2 Tamper-Resistant Outlets
Older homes do not have technology that saves children. Most of the children injured by inserting objects such as keys or hairpins into electrical outlets.
These injuries can be prevented by using a plastic outlet cap which is a common solution to prevent children from sticking objects into outlets, but unfortunately, plastic caps are not the safest option and can be easily removed by a young child. Thus, a safer solution is by installing tamper-resistant outlets.
What is tamper-resistant outlets?
Tamper-Resistant Outlets are standard wall outlets that feature an internal shutter mechanism that protects children from sticking objects into the receptacle (like hairpins, keys and paper clips).
The spring-loaded shutter system in the outlet only allows electricity to flow when equal pressure is applied simultaneously to both shutters such as when an electrical plug is inserted.
During unused conditions, both shutters are closed, and openings are covered. The most important thing, tamper-resistant outlets can be install in older homes as it is easy to modify older home with tamper-resistant receptacles.
