AUTO - AIR BAGS |
|
An airbag, also known as a Supplementary/Secondary Restraint System (SRS) or as an Air Cushion Restraint System (ACRS), is a flexible membrane or envelope, inflatable to contain air or some other gas. Air bags are most commonly used for cushioning, in particular after very rapid inflation in the case of an automobile collision.

DROWNING |
|
Drowning is death caused by the filling of the lungs by a liquid, usually water, rendering breathing ineffective and leading to death due to asphyxia. Near drowning is initial survival of a drowning event, and can lead to serious secondary complications including death later on; cases of near drowning therefore also require attention by medical professionals. Secondary drowning is death due to chemical and biological changes in the lungs after a near drowning incident or exposure to chemicals. In many countries, drowning is one of the leading causes of death for children under 14 years old.

EARTHQUAKES |
|
An earthquake is a sudden and sometimes catastrophic movement of a part of the Earth's surface. Earthquakes result from the dynamic release of elastic strain energy that radiates seismic waves. Earthquakes typically result from the movement of faults, planar zones of deformation within the Earth's upper crust. The word earthquake is also widely used to indicate the source region itself. The Earth's lithosphere is a patch work of plates in slow but constant motion (see plate tectonics). Earthquakes occur where the stress resulting from the differential motion of these plates exceeds the strength of the crust. The highest stress (and possible weakest zones) are most often found at the boundaries of the tectonic plates and hence these locations are where the majority of earthquakes occur. Events located at plate boundaries are called interplate earthquakes; the less frequent events that occur in the interior of the lithospheric plates are called intraplate earthquakes (see, for example, New Madrid Seismic Zone). Earthquakes related to plate tectonics are called tectonic earthquakes. Most earthquakes are tectonic, but they also occur in volcanic regions and as the result of a number of anthropogenic sources, such as reservoir induced seismicity, mining and the removal or injection of fluids into the crust. Seismic waves including some strong enough to be felt by humans can also be caused by explosions (chemical or nuclear), landslides, and collapse of old mine shafts, though these sources are not strictly earthquakes. These sources will also show a different seismogram than earthquakes

SAFETY |
|
Safety is the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological or other types or consequences of failure, damage, error, accidents, harm or any other event. Protection involves here both causing and exposure. It can include physical protection or that of possessions. Safety is often in relation to some guarantee of a standard of insurance to the quality and unharmful function of a thing or organization. It is used in order to ensure that the thing or organization will do only what it is wanted to do.

SEAT BELT / SAFETY BELT |
|
A seat belt, sometimes called a safety belt, is a harness designed to hold the occupant of a car or other vehicle in place if a collision occurs. Seat belts are intended to reduce injuries by stopping the wearer from hitting hard interior elements of the vehicle or from being thrown from the vehicle. In cars seat belts also prevent rear-seat passengers from crashing into those in the front seats.
