The Need For Evacuation Sirens

A major fire in the downtown core of a major city would leave people stranded and unable to get out. Depending on the severity, some may not even be aware that an evacuation has been called for. Fortunately, many cities implement sirens to warn their residents of dangers such as fires, tornadoes, earthquakes, and other disasters.

Evacuation sirens such as this one provide a clear message during emergencies. In an emergency like a major fire or tornado warning, residents need to know they need to evacuate so they can get home safely while leaving room for accidents and having logistic limitations in mind while setting up evacuation plans. There is no way for everyone at once to get the word out without sirens. Not everyone owns a car, and even those that do would be unable to transport the entire city in time without major traffic jams or accidents occurring.

The siren is also more efficient than other warning signals like helicopters because it covers a larger area over land instead of air. It can warn people not only about emergencies taking place at the moment but upcoming decisions like evacuation plans as well. The sirens are small, too, so they can easily fit on top of buildings with minimal cost for installation or maintenance. Although getting around will still be difficult during emergencies if public transportation stops running due to the disaster, most people have cars that they could use during an evacuation despite the limited availability of parking spots.

At this point, most major cities have sirens as a fail-safe in the event of an emergency. However, older cities might not have this safety measure due to their age and lack of updates. While there are some smaller towns without them, they are less likely to be affected by major emergencies that would require evacuation than a larger city.

After a disaster like a fire or a tornado, people often feel sad about the unnecessary loss of lives due to preventable accidents from being stuck somewhere. A good way to prevent this is through education on using public services such as warning sirens properly, so people do not accidentally become trapped if they hear the warning but aren’t aware of what it means or why it is sounding off. This requires more work on the part of local governments or non-profit organizations.

If you are currently in danger, find your evacuation sirens and get to safety as soon as possible. If you are not, work with your state emergency management to ensure that everyone knows what these signals mean so that no one becomes trapped by an evacuation they didn’t ask for or understand the reason why it was happening. The more people who know about their existence, the better-prepared emergencies can be handled to prevent loss of life due to potentially avoidable accidents.

How Nurse Call Systems Work

When carrying a casualty to the side or foot of a bed. When loading a casualty into an ambulance. Carry the casualty down stairs head first if the lower limbs are injured. Keeping their backs straight, all the bearers should squat and grasp the handles with their inner hands, palms inwards. On the order “lift”. All rise together, holding the stretcher with arms fully extended and keeping it level.

When the patient has been placed on the stretcher the bearers should take tip their positions at each end of the stretcher. At least two trained bearers will be required to carry a stretcher and the person in charge of the casualty should always remain at the casualty’s head. If bystanders are available they should be used to help carry the stretcher to spread the load.

However, there should be at least one trained bearer at each end of the stretcher. Unless a casualty is suffering from shock, the head should be kept higher than the feet. So as a general rule the casualty should always be carried feet first. However, there are a few exceptions: When going up stairs or hills when the lower limbs are not injured. When going down stairs or hills, when the casualty’s lower limbs are injured or the casualty is suffering from hypothermia as shown in Nurse Call Systems .

At the order advance, move off together but walk out of step to avoid bouncing the stretcher. When you reach the ambulance, working together, gently and evenly lower the stretcher to the ground with the casualty’s head nearest the ambulance.

A few ambulances have flat built – in beds with grooves to take the runners of a standard stretcher. Three people will be required to load an ambulance that does not have a self loading stretcher system. The three people will be placed as follows: One to stand on either side of the stretcher and one inside to receive and guide the stretcher into place and secure the stretcher. If there are only two berths, always load the left one first.

If loading a trolley bed into an ambulance, two bearers should take up their positions, one on each side of the trolley bed. Working together, raise the trolley bed to the required height and carry it head first into the ambulance as shown in Nurse Call Systems.

One bearer takes hold of the handles at the rear and gently withdraws the stretcher. As it is withdrawn a second bearer takes up position on the opposite side to the first bearer. (Bearers facing each other) when both have firm grip, the stretcher is withdrawn and once clear of the ambulance, is lowered to the ground.
