Safety Management Solutions for Hazardous Chemicals in the Food Industry

With the continuous improvement of people's material living standards, the food industry has developed rapidly. Food factories have been built all over the country, which has led to economic development. At the same time, the risk and cost of control have also increased sharply. In food factories, hazardous chemicals are often used in production and processing, cleaning and disinfection, pest control, facility and equipment maintenance, etc. If the use of these hazardous chemicals is not effectively managed and controlled, it will cause food contamination or accidents.


Safety accidents are frequent, and the management of hazardous chemicals needs to be standardized


An explosion occurred at a bean filling factory in Niulanshan Town, Shunyi District, Beijing, on December 3, 2019.

At around 9 o 'clock on November 29, 2017, employees of Lihejiang Guangtai Food Factory in Qinnan District, Qinzhou City, Guangxi Province, died after inhaling high levels of carbon monoxide and hydrogen sulfide toxic gases.

At 13:00 on March 6, 2003, the refrigeration workshop of Ruilin Food Co., Ltd., Tianyuan Development Zone, Deyang City, Sichuan Province, was broken open by ammonia gas, resulting in large ammonia leakage, resulting in casualties.

Common Hazardous Chemicals and Their Dangers in Food Industry


Food processing uses combustible raw materials. Grain, oil, sugar, dried fruit, algae and starch in the raw materials used in food processing are all combustible items, especially the mixture formed by starch, granulated sugar, flour, cocoa powder, milk powder, grain powder, coffee powder and air will explode. Edible oils such as sunflower seed oil, soybean oil, corn oil, cottonseed oil, sesame oil and linseed oil contain a lot of unsaturated fatty acids, easy to occur spontaneous combustion.

Flammable and explosive dangerous substances are used or produced in food processing. In water treatment, carbon dioxide purification and other processes need to use strong oxidant and other flammable and explosive dangerous goods. Improper storage and use may cause fire and explosion accidents.

The refrigeration technology widely used in the food industry requires a large amount of liquid ammonia refrigeration. Ammonia is a class B combustible gas with explosion limit of 15%-30.2%. Gas, fuel oil and other flammable and explosive dangerous goods used in baking furnace heating, gas fire and explosion risk is very great.

Dust will be produced in the process of conveying, sorting, crushing, separation, mixing and drying. Most of the dust in food processing materials can explode.The cooking process of food is widely used in electricity, oil, gas and other heating;
Because of fuel oil, gas leakage easy to cause fire risk.

There is a fire risk during the packaging of finished products. Modern food industry is widely used in polyethylene, polypropylene and other plastics, aluminum foil composite film, paper composite packaging materials are flammable and combustible materials. Packaging methods mainly include hot plate, pulse, high frequency, ultrasonic heat sealing and other methods, all of which melt plastic products by heating to achieve the purpose of sealing. If the operation is improper, it is easy to cause the combustion of packaging materials.
