Are indoor fire hydrants installed in the hardware warehouse of my own company?

We haven’t set it up. The reason is that the area is too small, and an outdoor fire hydrant is installed near the warehouse entrance.

According to Code 8.3 – Locations for installation of indoor fire hydrants, etc., 8.3.1: Except as provided in Article 8.3.4 of this code, the following buildings shall be equipped with DN65 indoor fire hydrants: 1 Factories (warehouses) with a floor area greater than 300 m2； 2 Buildings such as station, port, and airport waiting halls for trains (ships, planes), exhibition buildings, shops, hotel buildings, ward buildings, outpatient buildings, library buildings, etc., with a volume greater than 5000 m3 ； 3 First-class and A-class theaters, theaters and cinemas of other categories with over 800 seats, as well as auditoriums, gyms, etc. with over 1200 seats ； 4 Other civil buildings such as office buildings, school buildings, and non-residential residential buildings with more than 5 floors or a volume of over 10,000 m3 ； 5 Residential buildings with more than 7 floors shall be equipped with an indoor fire hydrant system; when this is truly difficult, dry fire risers and indoor fire hydrants of DN65 without hydrant boxes may be installed instead. The diameter of the fire service riser shall not be less than DN65. Note: Single-story or multi-story factories (warehouses) of Classes D and E with a fire resistance rating of Class 1 or 2 and a low amount of flammable materials, as well as factories of Class D with a fire resistance rating of Class 3 or 4 and a building volume of 3000 m3 or less, and factories of Class E with a fire resistance rating of Class 3 or 4 and a building volume of 5000 m3 or less (warehouses), may not be equipped with indoor fire hydrants. Grain warehouses and vaults do not require such installations either. Interpretation of the provisions: In single-story factories with fire resistance ratings of Class 1 or Class 2, where there are areas with different production functions, it is necessary to determine whether indoor fire protection water supply systems should be installed in each area based on its fire hazard level. In a multi-story factory building with fire resistance ratings of grade 1 or 2, if there are fire compartments with different production functions, and these compartments are separated vertically by fire barriers (such as fire walls), it is possible to determine whether fire protection water supply systems should be installed for each compartment based on its respective fire hazard level. In factory buildings with multiple floors rated as fire resistance class I or II, if fire protection water supply facilities are installed, fire hydrants shall be provided on each floor. In single-story or multi-story factories (warehouses) of categories D and E with fire resistance ratings of Class I or II, where there is little combustible material and a fire, if it occurs, will not result in a large area of fire damage – for example, if the affected area does not exceed 100 m2 and no significant economic losses are incurred – then fire protection water supply systems may not be necessary for such buildings. Indoor fire protection water supply systems should still be installed in Class D and E factories where there is a large amount of combustible materials, such as quenching tanks; and in Class D and E warehouses where there is plenty of combustible packaging material, including wooden boxes for packaging machines and cardboard boxes for packaging light bulbs. I’m stunned~ I can now make judgments by referring to building codes and other relevant materials.

3# National Spirit: Our unit’s hardware warehouse doesn’t have indoor fire hydrants because of its small size.

What was said upstairs is correct. In single-story or multi-story factories (warehouses) of categories D and E with fire resistance ratings of level 1 or 2 (including those containing both flammable and non-flammable materials), there is little combustible material; therefore, even in the event of a fire, it will not cause a large-scale fire. For example, if the area affected by the fire does not exceed 100 m2 and no significant economic losses occur, then it may not be necessary to install fire-fighting water supply systems in such buildings. In Class D and E factories, there is a large amount of combustible materials, such as quenching tanks; in Class D and E warehouses, there is also plenty of combustible materials, including various combustible packaging materials, wooden boxes used for packaging machines, cardboard boxes used for packaging bulbs, etc. Nevertheless, indoor fire protection water supply systems should still be installed. Factories (warehouses) with a floor area of more than 300 m2 need to be equipped with fire hydrants, while those with a smaller area do not necessarily require them. This is merely my personal opinion

Our factory’s fuel storage area consists of buildings with a fire resistance rating of level 2. Strict management systems have been established for the oil pump rooms, fuel storage tanks, and oily wastewater tanks, with dedicated personnel in charge of their supervision!

Our hardware warehouse is a dedicated storage facility; aside from metal items, there are very few flammable substances in the warehouse. Nevertheless, we have installed four fire extinguishers. Additionally, there is an underground fire hydrant located near the warehouse, which can be used to control a fire in case one breaks out!

According to the regulations, it is not necessary to set anything up; just placing a few fire extinguishers is sufficient.

Our company’s hardware warehouse stores metal products such as bolts, flanges, valves, drill bits, etc.; there are no fire hydrants installed. There are two dry powder fire extinguishers. However, after reading Guohun’s post, I believe we meet the safety requirements.

Fire hydrants should be installed; there are also flammable items in the hardware warehouse. For example, electric fires
