2. Read the text and make up a the report “Ecological and Safety Concerns: Problems and Solutions.” Use the answers for the questions given below.

  1. Why are the gas types extinguishers considered the most suitable for fires involving computers?

  2. What happens when the operator squeezes a handle of extinguisher?

  3. Why was the pro­duction of Halon banned?

  4. Why is it important to protect the layer of ozone?

Both carbon dioxide and Halon extinguishers have the gas in liquid form under pressure in the container. When the operator squeezes a handle, the liquid flows out of the container and becomes a gas that covers the fire. Liquefied gas extinguishers leave no water or powder. For this reason, the gas types are the most suitable for class C fires involving computers or other delicate electrical equipment that could be damaged by other types of extinguishers. In 1992, more than 85 nations agreed to ban the pro­duction of Halon by Jan, 1, 1994, because Halon harms the ozone layer in the earth's upper atmosphere. This layer of ozone protects plants and animals from most of the sun's ultraviolet rays. The agreement, which also allowed for the continued use of stored or recycled Halon, was an amendment to the 1987 Montreal Protocol on Substances That Deplete the Ozone Layer
