Fire prevention in pig farm

Now pig farms will introduce various types of pig raising equipment. In order to avoid unnecessary losses, we must do a good job in safety protection, especially fire prevention. Once a fire occurs in the pig farm, not only a large number of pigs are burned, but even the pigsty will be burned. So the following is a brief introduction to the specific work of fire prevention in the pig farm.
1. Pig farm construction
Pig farms must be located far away from residential areas and factories, not too close to the forest, so as to prevent people from accidentally using fire! When planning the layout of pig farms, each pig house should be separated as far as possible, and a fire passage should be drawn in the middle. Choose fire-resistant building materials as far as possible, and use less flammable materials, such as wood, plastic cloth must be used with caution!
2. Wire circuit
The installation, use, laying, maintenance and detection of electric appliances and their lines and pipelines in the pig farm must conform to the technical standards and management regulations for fire protection. The circuits in the shed shall be checked regularly, and the old wires shall be repaired and replaced in time to prevent the short circuit of wires from causing fire, and leakage protector shall be installed.
3. Heating equipment
No inflammable materials can be placed near the power generation equipment and heater of the pig farm. The boiler for heating by fire is used, and the wall contacting the chimney is separated by fire-resistant and heat insulation materials to prevent sparks, thus causing a large area of fire in the pig farm.
4. Fire fighting equipment
The pig farm shall be provided with fire-fighting channels, fire extinguishers and fire pumps, and the fire-fighting equipment shall be checked regularly, all obstacles of the fire-fighting equipment shall be removed, and the old and damaged fire-fighting equipment shall be replaced! The personnel safety fire-fighting training and drill shall be carried out regularly every year.
5. Personnel quality
Pig farmers should develop good habits, try not to smoke in the pigsty, cigarette butts should not be thrown around! In addition, pig farmers should deal with the relationship between good people, never make trouble, and make enemies with others, for a small thing, it is not worth causing a big disaster.
