9 percent
Burn injuries 10 minutes of injury need to be __ within approximately the first
Cooled down
Bums are classified according to the___ of injury
Depth
___ damage to soft tissues, but also internal iniuries to the body as a whole burns can cause not only severe
Electrical
A superficial bum is an injury that involves only the ___ layer of the skin
Epidermal
The three layers of the skin are the
Epidermis, dermis, subcutaneous
The tough and leathery dead soft tissue formed in a full-thickness burn injury is called
Eschar
All layers of the skin are damaged
Full thickness
One method that the EMT can use to estimate the body surface area damaged by a burn is the
Rule of 9
A partial-thickness bun is also called a(n) -degree burn
Second
Once the EMT has determined that the scene of a burn emergency is safe to enter, he should immediately take
Standard precautions
Examples of superficial bums include a minor
Sunburn
All of the following are important factors to consider in determining burn severity except
ambient environmental temperature
In managing a burn correctly, an EMT may take all of the following steps except
apply ointments or sprays
When dealing with chemical buns, the EMT should remember that dry chemicals should be

The innermost layer of the skin is the
subcutaneous
An example of a superficial burn would be a(n)
sunbum
