Smoke detectors (smoke alarms) are one of the most important safety devices in your home. If your home has well-maintained smoke detectors, the chances of your family surviving a house fire are greatly increased. From 2003 to 2006, 66% of fatalities due to house fires occurred in homes without working detectors (National Fire Protection Association).

Most homes have smoke detectors, but many times they are not located properly or are not working due to lack of maintenance. Of course, a smoke detector in the wrong location or one that no longer works because it has a dead battery provides no protection for your family. The Electric Connection, a fully licensed, bonded and insured electrician in Burbank CA, knows the most current code rules for smoke detector placement and they can install or replace your smoke detectors for you.

Maximizing Protection

Your family will have maximum protection if:

Can I install them myself or should I have my Burbank electrician install my smoke detectors?

You can purchase battery-operated smoke detectors from a hardware store and install them yourself. (If you decide to install your own smoke detectors, check your local building code for placing them.) For detectors that are wired into your electrical system, the U.S. Fire Administration recommends that detectors be installed by a qualified electrician. The Electric Connection, a local electrician in Burbank, can often schedule an electrical service call appointment for the following day.

Are they expensive?

Depending on the type of detector you decide on, they can run from $10-$40 each, not including installation costs. You can often get a ballpark price over the phone for installation pricing from a Burbank electrician.

How should they be maintained?

Most detectors start “chirping” when batteries have run down. In addition, the U.S. Fire Administration recommends testing them monthly. They recommend:

Are your detectors properly positioned?

The guidelines given here can help you determine if existing smoke detectors are properly positioned. If you are going to install battery-operated ones yourself, follow the placement requirements of your local building code. In general, it’s recommended that you have a smoke detector:

Within these general guidelines, detectors should be placed where smoke can be readily detected — high up on walls or on the ceiling (smoke rises) and at a distance from windows, fans, and vents that might blow smoke away from the detector.

If the smoke detector is wired into your electrical system, it should not be on a circuit that can be turned off with a wall switch. It’s always best to consult with a licensed Burbank electrician when it comes to hard wire some detector installations.

If a smoke detector is placed too close to a kitchen stove or shower, it can be triggered unnecessarily by steam or normal cooking smoke. Better to move it to a different location that also meets general safety guidelines and your local building code.

If you are uncertain about placement or need help with installation or battery replacement, call a qualified electrician in Burbank, such as The Electric Connection or visit our website.

High temperatures cause conductors to expand and hence increase in length. The converse is true for low temperature conditions. The change in length varies from one conductor to another depending on its thermal expansivity. The length of copper conductors, for instance, changes by 5 feet per 1000 feet of length when the conductor temperature changes from 100 – 0°, while aluminum changes by about 7 feet. The length increases with increase in temperature and reduces with reduction in temperature.

This increase or decrease in length is of great concern when installing power transmission lines between poles and towers, or when installing other power connectors. There must be an allowance for this change in length since it can cause catastrophes if it’s not there.

Weather changes are associated with increase and decrease in temperature and thus affect power transmission lines and other conductors. However, change in temperature is only one factor that affects power lines. Below are the changes that occur to power lines and other conductors as a result of weather changes:

The amount of heat dissipated from power conductors is reduced during hot and calm weather conditions. Basically, if the temperature of air around the cable is low, more heat is lost from the cable to the air. If the air is already hot, the exchange of heat is lesser. This low heat dissipation causes the lines to overheat. However, the rise in conductor temperature (overheating) worsens when cables are transmitting too much power than required. The first effect of this increased conductor temperature is snagging, which is the downward bulging of the cable between two poles, caused by the increase in the length of cables.

Snagging is largest during extreme hot weather (largest increase in temperature) conditions experienced in summer. The increase in length results to downward bulging of the cable due to the effect of gravity. Excessive sagging is dangerous if it goes below the accepted height clearance – cables could come into contact with trees, buildings and other structures underneath, causing electrocution and fires.

Excessive sagging represent an added weight on the power line and this increase may cause the line to fail or to pull down weak poles and towers. The effects can be small but gradual and so the poles and towers will finally come down or require some adjustment/replacement after some time, which is costly. This sagging can also cause the lines to short out. Excessive sagging is also costly since it leads to increased electrical resistance. This means that a sagged power line transmits lesser current than it normally does, thus causing under-feeding of electrical equipment and industries. It is also costly and time consuming to rectify a sag.

Do me a favor and imagine that you are in need of suggestions for a Fourth of July party. You head to via Wikipedia

Of course, I’m not talking about snap pops, black cats, m-80s, or even those cool little paper cars that gush sparks, travel four feet, and then burn to death in a microblaze reminiscent of a 1970s action film.

I am talking about the ones that explode up there, the ones you have to tilt your head back to see. That the fireworks explode in the night sky is important because the very act of looking up immediately takes you out of the mundanity that the rest of the holiday will surely deliver – the planning, the decorating, the complications. No more overflowing trashcan with wing sauce-smeared cocktail napkins. No more ordinary stuff.

At the heart of the Fourth of July is a spirit of independence that is, actually, a big deal. When your eyes are on what’s going on at ground level, it can be hard to realize how big a deal ideas like independence and sacrifice are. Once your attention is arrested by the spectacle of fireworks happening up there in the sky, you’re taken out of the everyday and able to reflect on these things, which is important, I think.

2. They are glorious.

“And the rockets’ red glare/ The bombs bursting in air,” goes the song. Did you know that the word “rocket,” in the sense of the combustion-fueled projectile, dates all the way back to 1566? The Oxford English Dictionary notes that rockets have historically been “used for signalling, in maritime rescue, for entertainment, and as a weapon.” Fireworks symbolize communication, violence, and entertainment: A strangely fitting mix for the complex human heart.

The red glare of the rockets in “The Star-Spangled Banner” refers to the bombardment of Fort McHenry in the War of 1812. That the fort was not taken during the battle is indeed glorious, and fireworks are a reminder of the fortitude of the people who fought and suffered to keep America independent in 1776 and again in 1812. Boom. (Literally: boom!)

3. They are beautiful.

So, those are my three reasons that fireworks are the most important part of any holiday festivity: They happen above you; they are glorious; and they are beautiful. I think these are pretty good reasons for making sure you see some fireworks this Fourth of July.

Take a moment out of the hectic festivities to reflect on the spirit of rebellion, creativity, and inspiration that is involved in claiming and defending independence from parties eager to exploit the vulnerable. This is about more than just us. This unites us across time and space. Fireworks reflect the beauty of standing together for what is right, even when it hurts.
