Ordinary, untempered glass doors will shatter into big, sharp pieces. These are quite hazardous. Other big pieces of shattered glass may fall off the door as a result of the collision, while other jagged-edged fragments may stay in the door frame. Each year, hundreds of people are killed by broken glass scattered on the streets after a storm, and thousands more are injured.
Glazed doors are safer than ordinary glass doors because they're made of tempered glass that's been specially treated to be resistant to breakage. Glazed doors also tend to be thicker and better constructed overall - which means they're less likely to break in the first place. However, even glazed doors can cause injury if someone is hit by one of them. The glass could cut or stab the person.
It's best not to open a door when someone isn't home. That way, they have time to clear the doorway before entering or exiting their house. If it's necessary for you to enter their house, go from room to room until you find a way out. Don't wait for the owner to warn you that you can come in - even if they do have an "open house" sign up. You never know what might happen to someone who is sick or injured if you don't act quickly enough.
People sometimes use broomsticks to make holes in closet doors so they can smoke inside the closets.
Tempered safety glass has a distinct breakage pattern than conventional clear glass. Tempered safety glass, unlike regular window panes or mirrors, does not shatter into sharp, jagged fragments of shrapnel-like glass when struck. Instead, it crumbles into little pebble-like fragments with no sharp edges. This makes tempered safety glass less dangerous if it is broken into small pieces.
In addition, the thin film of metal used in tempered safety glass (usually steel or aluminum) acts as an effective barrier to blunt any sharp fragments that may be released during trauma-induced shattering. These fragments are well-bound to the metal film and so do not pose a risk of serious injury or death if they land outside of the victim.
The protective qualities of tempered safety glass can also be attributed to the fact that it is more brittle than other types of glass. If someone tries to break tempered safety glass, they will usually be able to do so only after considerable effort. This makes shattered pieces less likely to be thrown with enough force to cause serious injury or death if they hit someone or something solid.
However, just because tempered safety glass is more fragile than other types of glass doesn't mean it is completely immune to harm. If enough pressure is applied to one piece, it could still break. The key word here is "enough." Pressing too hard on tempered safety glass might cause it to break into sharp fragments.
Temperature variations are the most common cause of breaking. For example, if it's cold outside and a heat vent is positioned extremely close to the glass door pane, the fast heating of the glass may cause the pane to expand rapidly, resulting in a crack that leads to shattering. The same thing would happen if there was a space heater near the glass door frame but not directly under the glass.
Lightning is another cause of window breakage. If a bolt of lightning strikes near a house with glass doors, it can be strong enough to break glass panels inside the house.
If you use storm windows, high winds can be the cause of broken glass. Storm windows are often made of thin plastic instead of wood, which can be damaged by high winds.
Finally, vandalism is also a cause of window breakage. This includes acts of violence like shooting out car lights or throwing rocks through windows. Vandalism can also mean people who enjoy causing chaos when there's no one around. For example, someone might use spray paint to write "party" on a wall then cover it up when they leave. In this case, the damage has been done but not necessarily by a person.
In conclusion, temperature variations, lightning, wind, and vandalism are all causes of glass breakage. These factors should be considered when choosing where to place storm windows or light curtains.
Warning. Physical risks include broken glass and other sharp items. Broken glass can also pose a health risk if it is tainted with harmful chemicals, blood, or infectious agents that enter the body via a cut or puncture. The U.S. Occupational Safety and Health Administration (OSHA) regulates many forms of hazardous materials exposure, including for employees working with broken glass.
Toughened glass, such as that used in shower screens, is the only form of glass that has the potential to "explode." Other varieties of glass, of course, can shatter and break. Exploding glass is a phenomena that occurs when toughened (or tempered) glass abruptly breaks (or explodes) for no apparent cause. The term "explosion" may be somewhat misleading, as there is no fire or spark involved; instead, the glass simply breaks into many small pieces.
People have been killed by broken glass from exploding windows. While this type of damage might happen with enough force to kill someone, it's very unlikely. More likely dangers include being hit by flying glass or broken furniture.
Tempered glass does not explode like novelty items or party glasses. Instead, it breaks into small sharp-edged fragments that are capable of cutting people. If you are asked to clean up shattered window panels, take the time to do so carefully. You could be exposed to dangerous chemicals if you aren't careful with your work space.
If you are the owner of a business that uses glass, you should know how to prevent exploding glass. One way to do this is by using protective film on glass that is subject to high levels of traffic. This will help reduce the chances that something will get through and cause an explosion.
Of course, the best way to keep everyone safe at your site is to use proper safety procedures.
The hazard of having glass in or near your door is that prospective burglars can shatter it and reach through to gain in without having to pick or break a lock. That implies that even if the robber manages to smash the glass, they'll still want a key to gain in. You could reduce this risk by installing security locks or bars on all window frames.
There's also the risk of injury from broken glass. Even if you don't suffer a cut or bruise, you could be exposed to bacteria that live in floorboards and walls. These organisms can cause diseases such as strep throat and diarrhea.
The best way to avoid these risks is with deadbolts instead of keys. This will make breaking into your home much more difficult. It also helps if you keep vegetation trimmed close to your house so intruders won't be able to use it for cover while trying to break in.
If you have glass doors, you should check with your contractor or building inspector to make sure that they're up to code before you move in. Some states require doors to have metal inserts to prevent glass panels from being used as weapons or projectiles.
You should also know that not all burglaries are committed by criminals. Your neighbor might be using information from crime scenes when putting together their home invasion lineup.
