To avoid fire, observe the following rules:
Burning substances and fluids should be stored away from fire and heating appliances;

-Defective electrical equipment can not be used;

-Do not immerse the power plug into a socket at once;

-Do not forget that the match is not a toy;

-In the event of a fire, it must be free of any accessory floors and balconies so that it does not interfere with the outdoors;
-In case of fire:
-Notify me of immediate notification of firefighting service 101;
-Try to remove the fire by using the available tools (fire extinguishers, water, sand, pallets);
-Limit the airflow to the burning room (do not open the windows and doors if necessary), leave the room immediately with strong smoke and close the door firmly;
-Protect your eyes and respirators with respirator, cotton mask, wet cloth or towel when leaving the room.

Combined fire-fighting vehicles

The fire extinguisher is intended for removal of flammable materials, even when the air is absent. There is no difference in fire extinguishers, electrical appliances, chemicals, archives and museums. It is not afraid of low temperatures.
The fire creates material damage to the people. In a few minutes or hours a huge amount of people's wealth will burn and burn. Smoke, carbon dioxide, and other harmful odors and gases emitted during the fire, are released into the atmosphere and break the air. It also causes injury to people, even death. All this requires joint study of labor protection with fire prevention measures and safe handling practices.
At present, the textile enterprises of the republic have been working to reduce fire risk. In particular, there is a risk of electric shock at enterprises and electrical equipment that is completely hazardous. The mechanized and automated fire-extinguishing systems are increasingly being used.
However, it should not be forgotten that the main responsibility for prevention and debris removal is the responsibility of people and that they fully meet all the requirements of the fire extinguishing technology. In textile factories, these activities should be carried out systematically according to regulations, fire safety rules, guidelines and other documents.

1. The height of the stormy lightning stroke is determined as follows. For a type A zone:

h = (R_X + l,63 • h_X) / l,5 ,
R_x=(64-16)^1/2=4*(3)^1/2
H=(4*(3)^1/2+1,63*3)/1,5=(4*(3)^1/2+13)*2/3=7,88
N = (S + 6 • h_x) • (L + 6 • h_x) • h • 10^-6
N=(4+6*3) * (7+6*3) * 7,88*10^-6 = 22 * 25 * 7,88 * 10^-6 = 4,33 * 10^-6.
2. The height of the stormy lightning stroke is determined as follows. For a type A zone:
R_x = (9+9)^1/2 = 3*(2)^1/2;
h = (R_x + 1,63 * h_x)/1,5,
h = (3*(2)^1/2 + 1,63 * 3)/1,5 = (3*(2)^1/2 + 13) * 3/2 = 6,1
N = (4+6*3) * (7+6*3) * 6,1 * 10^-6 = 22 * 25 * 6,1 *10^-6 = 3,355 * 10^-6
