The Recruit will also practice and master certain skills and will be tested on these skills. At the end of each subject there will be a quiz over the material that was taught. The firefighter is responsible for studying the material and practicing the skills.

There are 4 common hazardous atmospheres associated with fires or other emergencies.

Oxygen Deficiency

Elevated Temperatures

Smoke

Toxic Atmospheres

SCBA

Oxygen DeficiencyOxygen Deficiency

The combustion process consumes oxygen while producing toxic gases that either physically displace oxygen or dilute its concentration.

When oxygen concentrations are below 18%, the human body responds by increasing its respiratory rate.

SCBA

Elevated TemperaturesElevated Temperatures

Exposure to heated air can damage the respiratory tract, and if the air is moist, the damage can be much worse.

Excessive heat taken quickly into the lungs can cause a serious decrease in blood pressure and failure in the circulatory system.

SCBA

Con’t

Inhaling heated gases can cause pulmonary edema(accumulation of fluid in the lungs and associated swelling), which can cause death from asphyxiation.

The tissue damage from inhaling hot air is not immediately reversible by introducing fresh, cool air.

SCBA

SmokeSmoke

The smoke at a fire is a suspension of small particles of carbon, tar, and dust floating in a combination of heated gases.

Toxic Atmosphere Associated with FireToxic Atmosphere Associated with Fire

The firefighter should remember that a fire means exposure to combinations of irritants and toxicants whose toxicity cannot be predicted accurately.

In haled toxic gases may have several harmful effects on the human body.

04/21/23 11

SCBA

Con’t

Some of the gases directly cause disease of the lung tissue and impair its functions.

Other gases have no directly harmful effect on the lungs but pass into the bloodstream and to their parts of the body and impair the oxygen-carrying capacity of the red blood cells.

Limitations of SCBALimitations of SCBA

Limited visibility- The facepiece reduces peripheral vision, and facepiece foging can reduce overall vision.

Decreased ability to communicate-The facepiece hinders voice communications

SCBA

Con’t

Increased weight- The protective breathing equipment adds 25 to 35 pounds of weight to a firefighter depending on the model.

Decreased mobility- the increase in weight and the splinting effect of the harness straps reduce the firefighter’s mobility.

That concludes the self study part of the class. Now the student, that’s you, will watch the video Essentials of Firefighting Fire Self Contained Breathing Apparatus 1 & 2, which are located in the dayroom, right side of T.V., 2nd top draw. After the completion of the videos, return to the computer and take the quiz. There should be some answer sheets in the Recruit Training Book.
