C. 1. Read the text FIRE FIGHTING and answer the questions:

1. What are potentially serious fire hazards?

2. What services do fire fighters deliver?

Fire fighting is an important occupation in our society. Most com­munities have some kind of fire-fighting organization. Different kinds of equipment and training go into the development of an individual fire-fighting system. It is important that increasing research and training be implemented to improve the quality of community fire-fighting equipment and personnel.

Measures need to be taken to inform people what to do in case of a fire. All workers need to be instructed on what to do in the event of a fire, and should be examined from time to time to ensure that they fully understand. Fire drills should be held to consolidate this training in factories where there is a significant fire hazard. All workers should be trained when and how to raise the fire alarm and how to use fire fighting equipment provided on the spot, such as hose reels and extinguishers. In addition, many works have their own fire brigades manned by a full-time crew.

There are numerous categories of skill that the firefighter is expected to achieve. As fire fighting becomes more technical, the training of fire-fighting personnel is more specialized.

Hazards encountered by firefighters include the potential for:

- burns, dehydration and other effects of heat, smoke inhalation, heavy protective clothing, falling materials, or explosions;

- exposure to toxic materials and bacteriological or viral agents;

- physical injury and sensory damage from firefighting activities and noise levels;

- dealing with victims of fire in varying states of fright, panic, and injury, or participating in mob or riot control; and/or

- operating or riding on fire trucks at high speeds under adverse conditions, or flying in aircraft to reach crash sites or fires in outlying areas.

There are ongoing initiatives designed to improve the protective equipment available to fire fighters. Particular interest has centered on the development of lighter, yet more superior fire-fighting equipment and clothing. For example, most fire fighters now have personal alert safety systems. These electronic devices, worn by the fire fighter, emit a loud sound any time the individual doesn't move for over a thirty-second period of time. This helps to locate any fire fighter working in a smoke-filled room. Another piece of equipment that is helpful to fire fighters is the pressure ventilator. The ventilator is placed inside a burning building to blow smoke out of the way so that the fire fighters are able to see more clearly.

In addition to their responsibilities in extinguishing fires, fire fighters also deliver other services in many communities. They often are qualified to deliver emergency medical services, as well as to cope with hazardous materials spills. Fire fighting is obviously one of the more dangerous occupations in the United States. In addition to prob­lems associated with the blaze itself, the firefighter is exposed to various toxic gases, and other hazardous chemicals. More than 100,000 firefighters are injured each year while fighting fires.

In all factories where more than fifty people are employed, it is a statutory requirement that the person in charge of the first aid box must possess a current first aid certificate issued by one of the voluntary first aid societies: the British Red Cross Society, the St. Andrew's Ambulance Association and others.
