Basic disaster prevention measures for indoor installations
classification index of disaster prevention measures 0-20 index 20-40 index 40-90 () above 90 1. the supply of fire water shall comply with the fire protection law and damage protection standards, the same as the left 2. Fire prevention of buildings and pillars 1. Usually not required. However, special occasions or combustibles such as storing ammonia or acetone should be considered according to their quantities. As for the support of containers, adequate countermeasures should be taken. According to the quantity of combustibles, the time required to be able to withstand complete combustion should be considered, and within this range, it should be treated as being able to withstand full load even in case of fire. In addition, as for the support of containers, adequate countermeasures must be taken, and the countermeasures that can withstand the time of 20-40 times of the index should be considered. Other measures are the same as those of left 2 and 3. The scope of countermeasures is expanded compared with that of classification 1. The same as left 4. It is usually not necessary to be the same as left 3. Automatic water spray, sprinkler, etc. 1, 2 and 3 are determined according to the building structure and internal storage. For containers or devices in projects with combustibles, they should be designed to directly cover the fire wall or liquid with spray. In addition, "scientific research should not excessively seek short-term goals, but hope to set up spray devices in the whole area. The spray volume should comply with the fire protection law and damage protection standards, etc. the spray volume should refer to the fire protection law and damage protection standards, etc. others are the same as the left, usually do not need to be the same as the left. 4. Endoscope (rotating floating direct reading flowmeter, observation window, etc.) When handling combustibles at a temperature above 80% of the flash point, use a camera equipped with a one-way valve or a facility based on this standard. Use a camera equipped with a one-way valve or an excess flow valve or a facility based on this standard. Close the camera or use a camera equipped with a one-way valve or a facility based on this standard. 5. Special measuring or operating devices are not usually required. For fire, the outflow of combustibles should be controlled at or to a minimum, Or install a block valve or a hazard prevention device of a container (reactor, etc.) to take dual hazard prevention measures or install a safety valve, etc. (installed on each unit of equipment respectively) 6. It is very important that all discharge, isolation and cooling equipment do not usually need discharge equipment, isolation equipment or cooling equipment to move combustibles from the building to other places, Sufficient equipment is required. 7. Explosion proof countermeasures for containers. All fire-proof equipment (such as inert gas filling or electrostatic elimination equipment, etc.) are set as special equipment maintained at the explosion limit, and the dilution or explosion-proof devices using inert gas are the same as the left, However, it is also necessary to install safety valves, etc. (ibid.) 8. Combustible gas detectors do not usually need to be set up in the whole area. Detectors that alarm below the explosion limit are directly connected with the fire protection system, and the others are the same as the left. 9. Countermeasures to prevent dust explosion are all in the hopper, piping and other places where powder explosion can occur, Connect inert gas or set electrostatic elimination device, the same as left, the same as left. 10. The explosion-proof and disaster prevention countermeasure 1 of fire water system usually does not need to be separated due to explosion. In order to protect the fire water piping or fire hydrant, it is necessary to separate the disposal of underground burying and barrier isolation from left 2, 3, 4, The disposal of underground burying and barrier isolation is the same as above, which makes the experimental machine unable to operate normally. 1. Remote operation 1 usually does not need to set up remote operation and monitoring devices. 2, 3, 4. The research of remote operation and monitoring devices is the same as above. 12. Explosion proof wall 1 usually does not need to be outside the danger, and each device should be set up in 2, 3, 4 particularly dangerous places, Each device should be set as the same as the left and the same as the above 13. Physical separation 1 separates the range of each process flow to control its loss below the preset maximum loss. The separation method is to set up a firewall or maintain a sufficient safety distance. Take measures to prevent fire from being led to other areas by drainage ditches. The method to separate from the left is to set up firewalls or maintain a sufficient safety distance. The rest are the same as the left 2, 3, 4. In order to reduce damage, we should fully study the layout of equipment, Separate the control room from the device on the same left as on the left 14. The ventilation of the building is all installed. The device with more than two air changes per hour is set. The device with more than 10-15 air changes per hour is set. The device with more than 15-30 air changes per hour is set. 15. Safety countermeasures to prevent building explosion 1 usually do not need to be for buildings exposed to explosion hazards, Measures to eliminate blast blast blast wave are the same as those on the left. 2.3.4 for buildings exposed to explosion hazards, measures to eliminate blast blast blast wave are the same as those on the left. 16. Fire resistant building structure 1 uses flame retardant jianjixi. When the original coal production capacity of 31million tons of building materials are stored in 7kl, the combustion time is at least 30 minutes. If approved sprinklers are installed, the pillars can be fully flame resistant. In addition, when there are combustibles of more than 7kl, they should be strengthened in proportion to their quantity, and the girders, ceilings, etc. should also be fully studied. The time of withstanding the index of 20-40 should be considered to be more than one time. The other is the same as the left 2, 3. Ibid., expand the disaster prevention area, and increase the strength by adding various additives, modifiers and fillers. The rest is the same as above, 4 is the same as above, and the left is the same as the left
