Food and Beverage Production Facility Fire Safety
Food and beverage production facilities bring very different fire characters under one roof: high-temperature oil and hood grease build-up on commercial cooking and frying lines, milk powder in spray dryers, explosive dust such as flour/starch/sugar, flammable liquid in distillation and alcoholic-beverage production, toxic/flammable gas in ammonia refrigeration, and high-rack storage of cardboard/plastic packaging. This article covers the real fire risks in food and beverage facilities, the measures to take, and the recommended suppression systems (wet-chemical hood, spark detection on spray dryers, foam, sprinkler/ESFR, and gas detection).

Food and beverage production facilities bring very different fire characters under one roof: hot oil in the deep fryer, explosive dust in the spray dryer, flammable liquid in distillation, toxic/flammable gas in ammonia refrigeration, and the high fire load of packaging. This article covers the real risks, measures, and recommended suppression systems.
Risk: fire character varies by process
- Deep fryer / cooking oil and hood grease build-up — oil fire that cannot be extinguished with water,
- Spray dryer (milk powder), flour/starch/sugar — explosive dust,
- Distillation / alcoholic beverage — flammable liquid and vapor,
- Ammonia refrigeration — toxic and flammable gas,
- Cardboard/plastic packaging — high-rack fire load.
Measure: cooking and hood grease fire
Hot oil cannot be extinguished with water; water splashes and enlarges the fire. The solution:
- Wet-chemical hood suppression — coats the surface through saponification, cutting off oxygen,
- The system also cuts the fuel/gas supply,
- Grease build-up in the hood and exhaust ducts is cleaned regularly (the most frequent fire cause).
We covered hood suppression in our hood article.
Measure: dust explosion (dryer, mill)
- Housekeeping that limits dust accumulation,
- Spark detection-extinguishing at dryer outlet and pneumatic transport,
- Equipment grounding + hot-surface monitoring.
Measure: alcohol / distillation
- Separate, ventilated design away from ignition sources,
- Gas/vapor detection + ATEX-compliant equipment,
- Foam + containment for flammable-liquid surface/spill.
Recommended suppression systems
| Section | Recommended system |
|---|---|
| Cooking/frying + hood | Wet-chemical hood suppression |
| Spray dryer, mill, dust transport | Spark detection-extinguishing |
| Distillation/alcohol, oil storage | Foam addition + containment |
| Ammonia machine room | Gas detection + ventilation |
| Packaging / high-rack storage | Sprinkler / ESFR |
| Electrical, control room | Clean-agent gas |
Summary
Food and beverage facility fire safety is built section by section: protecting hot oil with wet-chemical hood, dust with spark detection, alcohol/oil with foam + containment, ammonia with gas detection, and storage with sprinkler/ESFR. All are based on NFPA 96/UL 300 + NFPA 13/11 + EN 12845/BYKHY (Article 57). For the general approach see our factory/industrial facility article. At A-Pro Engineering we design hood suppression, spark detection, foam, and sprinkler/ESFR for food and beverage facilities in an integrated way; contact us for your project.
This content is for information purposes. Binding design must be done on a project basis based on each process section, fire load, and actual facility conditions, together with NFPA 96, UL 300, NFPA 13/11/2001, EN 12845, and the current edition of BYKHY.

Frequently asked questions
What is the biggest fire risk in a food production facility?+
There is no single risk; a food facility holds very different fire characters together. On commercial cooking/frying lines, high-temperature vegetable oil and grease building up in the hood create an oil fire that ignites easily and cannot be extinguished with water. Spray dryers (milk powder production) and processes handling flour/starch/sugar carry an explosive dust risk. Flammable liquid comes in with distillation and alcoholic-beverage production, and toxic/flammable gas with ammonia refrigeration. To these is added the high fire load of cardboard/plastic packaging. So the risk varies by process section, and each section must be protected by its own method.
How is a deep-fryer and hood grease fire fought?+
High-temperature cooking oil ignites when it reaches its flash point and cannot be extinguished with water — water flashes to steam on the hot oil, splashes the oil, and enlarges the fire. So a wet-chemical hood suppression system is used on commercial kitchen and cooking lines; a special chemical forms a layer on the hot oil surface through saponification, cutting off oxygen and preventing re-ignition. The system also cuts the fuel/gas supply at the same time. Grease build-up in the hood and exhaust ducts must be cleaned regularly; this build-up is one of the most frequent fire causes. We covered hood suppression in a separate article.
How are milk powder, flour, and sugar dust explosions prevented?+
Spray dryers (milk/whey powder), mills, and flour/starch/sugar transport lines create an explosive atmosphere because of fine organic dust suspended in the air; a spark or hot surface can trigger a dust explosion in an enclosed volume. As a measure, housekeeping that limits dust accumulation, spark detection-extinguishing on pneumatic transport and dryer outlets, equipment grounding, and monitoring of hot surfaces are applied. Spray dryers are high-risk equipment and are handled together with the manufacturer's process safety measures. Early detection provides the most effective protection by catching the triggering spark at its source.
What measures are taken in beverage and alcohol production?+
Distillation and high-proof beverage production (whisky, liqueur, spirits, etc.) carry flammable liquid and vapor risk; ethanol vapor can form an explosive mixture with air. These sections should be designed separately, ventilated, and away from ignition sources; gas/vapor detection and ATEX-compliant equipment should be used. Water alone is not enough for suppression; foam addition is considered for flammable-liquid surfaces and spills, and containment is provided in storage and filling areas. Fermentation and bottling areas carry more of an electrical and packaging fire character and are protected accordingly.
Which suppression systems are recommended in a food and beverage facility?+
The system is selected by section: wet-chemical hood suppression for cooking/frying lines and hoods; spark detection-extinguishing for spray dryers, mills, and dust transport lines; foam addition + containment for distillation/alcohol and oil storage; gas detection + ventilation for the ammonia machine room; sprinkler/ESFR for packaging and high-rack storage; clean-agent suppression for electrical and control rooms. On the detection side, aspirating systems add value in a dusty environment. The right set is evaluated separately for each process section and designed in an integrated way.
Which standards govern food and beverage facilities?+
NFPA 96 (and UL 300 for wet-chemical systems) for commercial cooking hoods, NFPA 13/EN 12845 for high-rack storage, and NFPA 11 for foam are the basis. For spray dryers and dust-handling processes, spark suppression and dust safety approaches (NFPA 61/652 framework) are considered; NFPA 2001 applies for clean-agent suppression. In Türkiye, commercial kitchen hoods fall under BYKHY Article 57 and design is based on these standards together with BYKHY. For related topics see our hood and chemical storage articles.
