Types of Possible Burns inAgricultural Mechanics
BURNS are injuries that destroy or
damage layers of skin and some-
times underlying tissue. Burns can be
caused by heat, electricity, chemicals,
radiation, and frostbite. When an acci-
dent results in a burn, everyone should
know what action is required. Adminis-
tering first aid may save a life. A burn
injury is often very painful to the victim.
The severity of a burn depends on the
depth to which it penetrates and the
size of the area involved.
Be prepared to treat burns by keeping a first-aid kit, in a dustproof container, easily
accessible. Check the first-aid kit often, reviewing the expiration dates on products and the
quantities of items present.
Objective:
� Identify the different categories of burns and describe the treatment for each.
Key Terms:

Types of Burns and Their Treatment
Although precautions are taken, hazards for getting burned or scalded often exist in agricul-
tural mechanics. Thus, knowing how to respond when someone receives such an injury is very

could occur.
Scalding occurs when skin comes into con-
tact with a hot liquid. Scalds from hot oil are usu-
ally more damaging than those from hot water
because oil heats to a higher temperature and the
thicker liquid sticks to the skin longer. Clothing
keeps hot liquid in contact with the skin, allowing
an injury to become more severe. Even steam can
cause an injury.
Summary:
� Burns are injuries that destroy or dam-age layers of skin and sometimesunderlying tissue. Burns can be causedby heat, electricity, chemicals, radia-tion, or frostbite. When a burn occurs,knowing first aid can reduce the sever-ity of the injury or even save a life.
Burns are given category, or degree,designation to assist with proper treat-ment. Minor burns can be treated withfirst aid, whereas more serious burnsrequire professional attention.
If the burn area is whitish, charred black, brown, yellow, or cherry red, professionalmedical attention is needed. Any of these colors indicates a third- or even fourth-degree burn. A second-degree burn usually shows redness. A first-degree burn isrecognized by a pinkish-red color.
Certain chemicals can produce severe burns. Hot liquids can cause scalding. Scaldsfrom hot oil can be especially severe.
Checking Your Knowledge:
� 1. Describe the appearance of a first-degree burn.
2. Describe the appearance of a second-degree burn.
3. Describe the appearance of a third-degree burn.
4. Describe the appearance of a fourth-degree burn.
5. Describe the recommended first aid for a chemical burn.
6. Explain why hot oil can cause a more severe burn than hot water.

Expanding Your Knowledge:
� Arrange a field trip to the local emergency response unit in your area. Request apresentation on how to treat burn victims. If a field trip is not practical, the emer-gency response unit may be able to attend a class session and share information onresponding to burn victims.
