The first thing we have to do is establish the etymological origin of the term salvage that we are now dealing with. In doing so we will discover that it emanates from the Latin and more exactly from the verb I will save, which in turn comes from salvus. This word can be translated as “healthy or whole.”
Rescue is the action and effect of saving or being saved (to protect, to free from a risk or danger, to insure). The concept can refer to a bodily rescue or spiritual.
The rescue of body, also know as lifeguard, refers to the physical help that is provided to someone in an emergency situation to allow their survival. This rescue can be provided spontaneously by one or more persons, or organized by a professional service (firefighters, paramedics, civil protection, etc.).
Precisely in this line we have to underline the existence of what is known as marine rescue, which is the entire set of actions that are carried out with the clear objective of ensuring the safety of all boats and people who at that time they are found in the waters of a certain place.
Thus, for example, in the case of Spain there is the Maritime Rescue and Safety Society, which is in charge of undertaking the aforementioned work. So much so that its main functions are to carry out rescue and search tasks, control what is maritime traffic or fight against what is pollution of the coasts and seas.
In order to carry out these tasks, it has a large fleet of vehicles, among which we should highlight both maritime units, such as tugboats or rapid intervention vessels, as well as air units.
On the other hand, there is also what is called water rescue, which is what lifeguards carry out on the beaches. Specifically, this type of rescue is divided into three specific areas: aquatic rescue, aquatic safety and preventive rescue.
Physical rescue usually requires the intervention of various equipment or materials, such as ropes, ladders, boats, stretchers, mats or hoses, as the case may be. Critical situations require great effort and courage on the part of the person performing the rescue. For this reason it is common for salvage to involve the intervention of some hero, as in the case of the rescues that took place after the terrorist attacks of the September 11, 2001 in the city of New York (USA).
The spiritual salvage, for its part, refers to the salvation of the soul. Whoever agrees to spiritual salvation manages to free his soul from eternal damnation, which includes torture and punishment after death and for all eternity.
The concept of eternal salvation depends on each religion. For Catholicism, saving the spirit implies reaching the heaven to spend eternity with God, something that is achieved when the person manages to get rid of sins. Otherwise, the subject ends up confined to hell.
