Q181 How is fire management carried out in the engine laboratory?

Engine test research is widely used in the development of industrial systems and innovative products such as automobiles, aviation, and marine. The engine described here is an oil-fueled engine. In the test, because the cylinder is ruptured, the flame is rushed, the oil is dripping, or when the carburetor is adjusted, the oil drips on the exhaust pipe (the temperature can reach 900 when it is red), etc., it is easy to fire.

Therefore, the following fire prevention measures should be taken.

1) The test bench of the engine test room should be located in:

In the first and second class fire-resistant buildings, the interior decoration and appliances are required to be non-combustible.

2) The fuel tank and the test bench should be set up separately, and the oil circuit system should be checked frequently for leakage, and the oil pipeline and fuel tank should be equipped with a good electrostatic grounding device.

3) The engine laboratory should be equipped with oil vapor hazard concentration alarm and fixed automatic fire extinguishing facilities, and at the same time equipped with small fire extinguishers to facilitate the extinguishing of the initial disaster.

4) Fireworks should be strictly prohibited indoors, and electrical equipment should meet explosion-proof requirements.

Due to the needs of the experiment, the bench of each laboratory contains a large amount of engine oil, diesel fuel and dangerous gases, which are flammable and explosive and relatively concentrated. Once these items are burned, they will soon form a fire, and if they are not controlled in time, they will ignite the engine body and the corresponding fuel pipeline in the experimental room, and even **, which is very dangerous. At present, most of the engine laboratories use gas automatic fire extinguishing systems to protect the safety of the protection area, and the heptafluoropropane fire extinguishing system is a fire extinguishing product in the engine laboratory, which is clean and pollution-free, has high fire extinguishing efficiency, and can quickly extinguish the fire.

Nianhai Fire is from Suzhou, you can ask.

(1) The person in charge of the construction site shall be fully responsible for the fire safety work of the construction site, and the construction unit shall actively supervise the construction unit to be specifically responsible for the fire management and inspection work on the site.

2) In the event of a fire or fire at the construction site, it should be reported to the public security fire department immediately and organize forces to extinguish it.

3) The construction site should establish and improve the fire prevention inspection system, and the fire hazards must be eliminated immediately.

4) According to the principle of "four do not let go", after the fire accident, the construction unit and the construction unit should jointly do a good job of on-site protection and on-site investigation with the fire department. Make suggestions on the handling of fire accidents and actively implement preventive measures.

5) The construction unit must have fire safety content in the "engineering contract" signed by the construction project, and the contract construction unit must jointly do a good job in fire prevention.

6) The construction site should be clearly divided into areas such as fire operations, flammable and combustible material storage yards, warehouses, flammable waste concentration stations and living areas.

7) There should be lighting equipment at the construction site at night, keep the passage of fire trucks unimpeded, and arrange forces to strengthen the patrol on duty.

8) when compiling the construction organization design, the general construction plan, construction methods and construction technology should meet the fire protection requirements.

9) The construction site should be equipped with sufficient fire-fighting equipment, and designated personnel should be designated for maintenance, management, and regular updates to ensure that it is complete and easy to use.

10) In civil construction, fire-fighting equipment and facilities should be equipped first, and outdoor fire hoses and fire hydrants should be laid if conditions permit.

11) During the construction operation, temporary buildings need to be erected, which must be approved by the technical person in charge of the construction enterprise, and should be dismantled in time after the construction is completed. Temporary structures or combustible materials shall not be erected under high-voltage overhead lines.

12) When thermal insulation and heating measures are used in winter construction, safety education should be carried out; During the construction process, special personnel should be arranged to patrol and inspect, and the hidden dangers should be dealt with in a timely manner.

13) The distance between welding and cutting operation points, oxygen cylinders, acetylene cylinders, and flammable and explosive materials shall comply with relevant regulations; If the above requirements are not met, the fire approval system should be implemented, and effective safety isolation measures should be taken.

14) The construction site should strictly implement the relevant documents of the superiors, strengthen the power management, and prevent electrical fires.

15) The welding and cutting operations on the construction site must meet the fire prevention requirements, and strictly implement the provisions of "ten non-burning electric welding".

Second, let every student learn fire fighting, know fire fighting, and understand fire fighting.

Third, let the children have a sense of fire protection and learn to adapt to changes.

It can be used to use a centralized water supply cooling scheme, composed of a refrigerator (air-cooled, water-cooled), a thermal insulation water tank, a water pump, a pipeline valve, etc., connected to each bench, through the branch water pipe ** cooling water, the temperature is about 20 degrees, which can simulate the centralized water cooling cycle of the cooling system after the engine starts, and does not need to be equipped with a fan fan on the bench, using Kaideli industrial refrigeration equipment, which can be more energy-saving and environmentally friendly.

Fire prevention inspection refers to the organization of the unit to inspect the unit, not only to have an inspection system, but also to the responsibility of the person, there is inspection, there are records, and do a good job of implementation. Carry out regular fire prevention inspections, generally taking a combination of regular inspections and key inspections (i.e., seasonal inspections and major festival inspections). Check the contents:

1. Fire safety in the production, storage, operation, transportation and use of fire, electricity, flammable dangerous goods and other important substances; 2. Whether the building structure, plane layout, water source and road meet the fire safety requirements; 3. Rectification of fire hazards; 4. The implementation of the step-by-step fire prevention responsibility system, the post fire prevention responsibility system and the fire safety system; 5. Whether the fire-fighting equipment and facilities are in good condition.
