C. 1. Read the text WORKPLACE FIRE SAFETY and answer the questions:

1. What does fire protection involve?

2. What are two important components of fires?

Fire protection is the study and practice of mitigating the unwanted effects of potentially destructive fires. It involves the study of the behaviour, suppression and investigation of fire and its related emergencies, as well as the research and development, production, testing and application of mitigating systems. Firefighters, fire investigators, and other fire prevention personnel are called to mitigate, investigate and learn from the damage of a fire. Lessons learned from fires are applied to the authoring of both building codes and fire codes.

As important as it is for each of us to take measures to prevent fires from happening, serious life-threatening and property-destroying fires occur. It is therefore important that measures be instituted to extin­guish the blaze. How this is accomplished will be determined somewhat by what type of fire is burning, by what fire-fighting equipment is avail­able, and the skills of those available to use the equipment.

Two important components of fires are smoke and flame. Flame is the luminous part of the fire that most of us associate with a blaze. A burning building with high shooting flames will attract attention. But a fire may not always have a flame. If there is little oxygen, for example, there is not likely to be a flame. A field of dry grass burning high in the mountains will have little flame because of the absence of oxygen at high elevations.

There is always visible smoke from any kind of fire. Smoke is made up of gaseous products that result from the burning of organic materials. Smoke is not only destructive at the scene of the fire, but it may be blown some distance and cause additional damage. More in­juries and deaths occur from smoke inhalation than from exposure to the heat and the flames generated by a fire. As the result of inhaling smoke, an individual becomes asphyxiated because the body cells do not receive the needed oxygen.

Even though most people think of fires as essentially identical, it is important to understand that there are several different types of fires. The particular classification of fire is based upon what objects are burning - which, in turn, impacts the measures needed to be taken to combat the fire. Even though we normally think that spraying water on a fire will effectively extinguish the blaze, there are certain kinds of fire for which such measures are ineffective and actually may serve to spread the fire.

Injuries from fires are the fifth leading cause of unintentional-injury deaths in the United States. It is estimated that fires cause more than 4,000 fatalities a year. Fires resulting in injury and death occur at all times of the year, though the peak mortality period is in the winter months - with January being the highest. This is because heating equipment such as furnaces, electric heaters, and stoves are in greatest use during this time. Every effort should be made to assure that any heating device is properly maintained.

Although many behavioral risk factors contribute to fires, three merit consideration are: use of alcohol, smoking, and activities associated with the use of matches and cigarette lighters.
