Water consumption for emergency spray system
Thread Content
The installation of emergency spray systems is quite important for emergency rescue. The requirements regarding the water consumption of such systems are specified in Article 5.1.1 of the \"Design Code for Emergency Spraying Systems in Petrochemical Industries\" SH/T 3205-2019: \"The water consumption for the emergency spraying system should be determined based on the maximum number of units that can be activated simultaneously. If there are more than two emergency sprayers or eye wash stations within the same system, the calculation should be based on the activation of two units at a time, with the required operation time being no less than 15 minutes.\" ” The interpretation of clause 5.1.1 of the \"Design Code for Emergency Scouring Systems in Petrochemical Industries\" SH/T 3205-2019 states that \"the water volume required in all MSDS (Material Safety Data Sheets) is 15 minutes.\" This water volume is a basic requirement for calculation, and the design standard of international engineering companies is also 15 minutes. The design water volume requirement of this standard is a minimum requirement; it should be increased appropriately as needed depending on the specific circumstances. For a device or unit, this amount of water is a requirement specified for that device; if there are multiple emergency showers and eyewash stations in the device, only one accident is taken into consideration (based on the principle that accidents do not accumulate). However, when two adjacent emergency showers and eyewash stations protect the same area, the situation in which both of them operate simultaneously should be taken into consideration. ” If there are many units within a plant, and the entire plant shares one emergency spray system, is then the water consumption of that system also determined based on the scenario where two emergency shower and eyewash units are in use simultaneously? :Q:Q:Q:Q:Q:Q:Q:Q
Yes, if the entire plant uses the same emergency spray system and there are multiple units, the water consumption of the system should also be determined based on the scenario where at least two emergency shower and eyewash stations are in use simultaneously. This is to ensure that in emergency situations, the system can provide an adequate amount of water for effective flushing. .
I guess you think the devices are all very small, so small that all the devices in a factory can fit inside one building or one laboratory.
Well, I’ve never seen a building this large before; it’s big enough to house a comprehensive petrochemical plant.
I think so too; following the fire water system, the calculation for the entire plant’s fire water system is based on the worst-case scenario requiring the highest amount of fire water, without any cumulative calculation.
