When deciding to organize on-site cooking to provide portions meals for workers When things get heated, the Board of Directors and HR department often focus all their attention on menus, pricing, or certificates. food safetyHowever, the real "shock" often comes from the technical infrastructure assessment phase by the authorities.
An industrial kitchen discharges hundreds of liters of grease, dirty water, and consumes a huge amount of gas every day. If strict regulations are not followed... Emission and fire safety standards (Fire safety), businesses not only face fines of hundreds of millions of dong but also risk fire and the suspension of their entire production chain.
So, the Emission and fire safety standards What are the current regulations? What infrastructure needs to be prepared? building communal kitchens Does it meet standards? Let's find out in detail with Tan Loc's technical experts.
1. Why are Emission and Fire Safety Standards a "Crucial" Issue?
Emission and Fire Safety Standards In communal kitchens, the State mandates a set of technical standards to control environmental impacts (grease-contaminated wastewater, smoke and dust) and prevent fire and explosion risks from industrial gas and electrical systems. Compliance with these standards is a prerequisite for factories to obtain legal canteen operating licenses and to ensure the safety of thousands of workers.
Many factories in industrial parks in Ho Chi Minh City and Binh Duong have had their electricity and water supply cut off, or their business licenses revoked, by the industrial park management board simply because the wastewater from their canteens had high levels of pollutants. BOD, COD Exceeding permissible levels, or a gas leak threatening adjacent warehouses containing flammable materials.
2. Discharge Standards: Solving the Problem of Oil, Grease, and Odor
Cook thousands industrial meals This means generating an extremely complex amount of waste. The treatment system must be designed comprehensively right from the blueprint stage.
2.1. Grease Trap System – Mandatory Requirement
Animal fats and food scraps, if discharged directly into the sewer, will quickly solidify, clogging the entire drainage system of the factory and killing the microorganisms in the central wastewater treatment system.
- Standard: Emission and Fire Safety Standards Requirement 100%: The kitchen sink and floor drain gratings must be directly connected to... 3-compartment grease trap Made of 304 stainless steel.
- Mechanism: Wastewater entering compartment 1 will retain coarse debris. In compartment 2, the flow design slows the water speed, causing the lighter grease to float to the top, while the clear water sinks. Compartment 3 will discharge the water (filtered with 85% grease) into the common wastewater collection system.
- Maintenance: Supplier industrial catering service They are responsible for regularly removing grease (daily or weekly) and transferring it to a hazardous waste disposal unit.
2.2. Floor Drains and Slope
When building communal kitchensThe floor area is always wet due to food preparation and industrial cleaning processes.
- An open drainage system made of stainless steel must be installed along the cooking equipment and tray washing area. The minimum floor slope must be 1.5% – 2% towards the drainage channels to ensure the floor remains dry, prevent slipping for kitchen staff, and ensure safety. food safety (Avoid stagnant, dirty water that breeds bacteria).
2.3. Exhaust Hood Systems
The smoke produced from frying contains many tiny oil and grease particles and CO2 gas. If left untreated, these will stick to the factory ceiling, creating unsanitary conditions and increasing the risk of fire.
- The range hood must be installed to completely cover the entire Asian or European kitchen system.
- Emission and Fire Safety Standards It is recommended to use exhaust hood systems with integrated grease filters (baffle filters) or electrostatic/water-based filtration systems. The airflow must be deodorized and filtered to remove grease before being released into the environment, ensuring it does not affect nearby residential areas or medical/electronic equipment manufacturing plants.
3. Fire Safety Standards: Absolute Prevention – Immediate Response
The kitchen is where all three elements of a fire converge: a heat source (stove), combustible materials (cooking oil, gas), and oxygen. Therefore, applying Emission and fire safety standards The rules here are much stricter than in the office area.
3.1. Fire compartment design and refractory materials
- Location: The canteen and cooking area must be located in a separate area, or completely isolated from the main production area by fire-resistant walls (minimum fire resistance time of 120 minutes).
- Fireproof doors: The passageways between the kitchen and the production workshop must be equipped with fire-resistant steel doors that automatically close upon alarm. The kitchen ceiling and floor must be made of non-combustible materials (such as stainless steel, ceramic tiles, or fire-resistant drywall).
3.2. The central gas system is absolutely safe.
This is the "heart" but also the "ticking time bomb" of the kitchen. When building communal kitchensUsing small, scattered 12kg gas cylinders in the kitchen is a serious violation.
- Independent gas storage: Industrial LPG (liquefied petroleum gas) storage tanks must be located outside the building, enclosed by a protective fence, with adequate ventilation, and at least 5-10 meters away from any open flames.
- Automatic shut-off valve: The gas supply pipe to the stove must be made of cast steel (impact-resistant). Emission and Fire Safety Standards Regulations require that this system be equipped with gas leak detectors installed directly under the kitchen floor. When a gas concentration exceeding the threshold is detected, the sensor will activate an alarm and automatically shut off the solenoid valve at the gas storage area, completely cutting off the supply.
3.3. Equipped with specialized fire-fighting equipment (Class F)
Many factories make the fatal mistake of equipping their kitchens with conventional powder or CO2 fire extinguishers.
- In the event of a Class F/Class K fire, spraying water or a high-pressure CO2 extinguisher will scatter the boiling oil around, causing the fire to intensify.
- Kitchen areas must be equipped with specialized wet chemical fire extinguishers. When sprayed onto boiling oil, this chemical creates a thick layer of soapy foam, instantly lowering the temperature and isolating oxygen, safely extinguishing the fire. In addition, fire blankets are also mandatory to cover burning pans of oil.
4. Infrastructure Differences Between Industrial and School Meals
The consulting capabilities of an industrial catering service provider are demonstrated through their understanding of the specific infrastructure of each project, enabling them to design a system that is both legally compliant and cost-effective. A prime example is the significant difference in wastewater discharge and fire safety standards between factory catering models and other catering models. school meals:
| Evaluation Categories | Industrial Kitchen (Factory/Workshop) | School Canteen (Boarding School) |
| Processing characteristics | Stir-fry or deep-fry large quantities over high heat to cook the dish quickly. Worker. | The dishes are mainly stewed, braised, and boiled. Deep-fried or stir-fried dishes are rarely used. |
| Emission Standards | Requirements: Extra-large capacity grease trap, industrial-scale organic waste (food scraps) collection system. | Medium-sized grease trap. Less grease, but requires stricter requirements for safe cleaning water discharge. |
| Fire protection system | The central gas storage facility has a large volume of gas and the highest level of fire protection due to its location within an industrial complex. | Use industrial induction cooktops or small gas systems, prioritizing solutions that do not produce toxic fumes in schools. |
| Layout space | The wind direction must be carefully calculated to prevent smoke and fumes from blowing back into adjacent production workshops. | Completely separate from the classroom area, with a dedicated access route for food delivery trucks. |
5. Five Steps to Assess the "Health" of Your Corporate Canteen Infrastructure
If your factory has already built and is operating a canteen, the Board of Directors and HR need to immediately audit the system following these 5 steps to avoid violations. Emission and fire safety standards:
- Check the fire safety inspection certificate expiration date: Is the fire safety design approval certificate for the kitchen area still valid? Have the fire extinguishers been refilled every 6 months?
- Gas sensor test: Try activating the gas leak sensor to see if the alarm sounds and the main valve closes automatically. (It is recommended to have a technician perform this.)
- Cleaning the range hood: Observe the filter on the exhaust hood. If grease is forming thick droplets, this is a warning sign of an extremely dangerous fire. A professional industrial cleaning service should be called immediately.
- Inspect the grease trap: Open the grease trap lid to check for grease backflow. If the sink area is draining slowly, it indicates a localized blockage in the system.
- Food Safety & Environmental Profile: Ensure that discharge logs, organic waste collection contracts, and septic tank/grease trap pumping invoices are fully documented.

7. Frequently Asked Questions About Canteen Infrastructure
1. My company rents a pre-built factory and now wants to renovate a corner for a kitchen, but the landlord won't allow us to dig the foundation to install a grease trap. Is there any solution?
In cases where excavation is not feasible, businesses can use floating grease traps made of 304 stainless steel, placed directly under the sink. Wastewater from the sink will flow directly into this floating grease trap before entering the main sewer line. However, this solution is only suitable for small-scale kitchens, and kitchen staff would have to manually remove grease daily, which is very laborious. The best solution remains outsourcing. industrial catering service Home delivery available.
2. Do fire safety standards prohibit the use of gas stoves in high-rise buildings?
While not entirely prohibited by law, the requirements for ventilation systems, sensors, and fire-resistant compartments are extremely expensive and stringent. Therefore, the current trend for canteens located on upper floors or in shopping malls is to switch to using 100% industrial induction cooktops. Induction cooktops do not produce open flames or CO2 emissions, minimizing the risk of fire and explosion.
3. Will the Department of Natural Resources and Environment fine those who release smoke from industrial kitchens into the environment?
Yes. According to environmental protection regulations, emissions from industrial kitchens must be treated. If a factory directly releases smoke containing grease and food odors into the environment, affecting nearby residential areas or factories and receiving complaints, authorities will measure the concentration of emissions. If the levels exceed the standards, the business will be fined and required to install a filtration system (water/electrostatic membrane) immediately.
