Where Should Sanitizer Chemicals Be Stored In A Food Establishment


Sanitizer chemicals are an essential component in maintaining a safe and hygienic environment in food establishments. From restaurants to food processing plants, these chemicals play a crucial role in preventing the spread of harmful bacteria and viruses. However, the proper storage of sanitizer chemicals is equally important to ensure their effectiveness and the safety of those working in the food establishment. In this article, we will discuss where sanitizer chemicals should be stored in a food establishment to maintain safety and compliance with regulatory standards.

Types of Sanitizer Chemicals

Before we delve into the storage guidelines, it’s important to understand the different types of sanitizer chemicals commonly used in food establishments. The most prevalent sanitizer chemicals used in the food industry include chlorine-based sanitizers, quaternary ammonia sanitizers, iodine-based sanitizers, and peracetic acid.

Chlorine-based sanitizers are widely used for their effectiveness against a broad spectrum of microorganisms. They are available in various forms such as liquid, powder, or tablets.

Quaternary ammonia sanitizers, also known as quats, are another popular choice in the food industry due to their non-corrosive nature and effectiveness in hard water.

Iodine-based sanitizers are known for their rapid killing action against bacteria and viruses, making them suitable for use in food establishments.

Peracetic acid is a strong oxidizing agent that is gaining popularity due to its ability to effectively sanitize food contact surfaces.

Each type of sanitizer chemical comes with its own set of storage requirements to maintain its efficacy and safety.

Regulatory Standards

The storage of sanitizer chemicals in a food establishment is not only a matter of best practices but also a regulatory requirement. Various regulatory bodies such as the Food and Drug Administration (FDA) and the Occupational Safety and Health Administration (OSHA) have set guidelines for the proper storage of sanitizer chemicals to ensure the safety of employees and consumers.

OSHA’s Hazard Communication Standard mandates that all chemicals, including sanitizer chemicals, must be properly labeled and stored to prevent accidents, spills, and exposure. Employers are required to provide training to employees on the safe handling and storage of chemicals.

The FDA’s Food Code provides specific guidelines for the use of sanitizer chemicals in food establishments, including their proper storage to prevent contamination of food and food contact surfaces.

Adhering to these regulatory standards is crucial for food establishments to avoid penalties, safeguard public health, and maintain a positive reputation.

Ideal Storage Conditions

The efficacy of sanitizer chemicals can be compromised if they are not stored under the appropriate conditions. Factors such as temperature, light exposure, and proximity to other chemicals can impact the stability and effectiveness of sanitizer chemicals. Here are the ideal storage conditions for different types of sanitizer chemicals:

Chlorine-based sanitizers

Chlorine-based sanitizers should be stored in a cool, dry, and well-ventilated area. Exposure to direct sunlight should be avoided, as it can degrade the chlorine content and reduce its effectiveness. Additionally, chlorine-based sanitizers should be kept away from acids, ammonia, and other reactive chemicals to prevent hazardous reactions.

Quaternary ammonia sanitizers

Quats are sensitive to temperature and pH levels, so they should be stored in a cool, dry place away from direct sunlight and extreme temperatures. They should also be kept separate from acids, alkalis, and other chemicals to prevent contamination.

Iodine-based sanitizers

Iodine-based sanitizers are sensitive to light and should be stored in a dark, cool place to maintain their effectiveness. They should also be kept away from direct sunlight and other reactive chemicals.

Peracetic acid

Peracetic acid should be stored in a cool, well-ventilated area and away from direct sunlight. It should be kept separate from incompatible materials such as strong bases and reducing agents to prevent hazardous reactions.

Storage Containers

In addition to the storage conditions, the choice of storage containers for sanitizer chemicals is vital to ensure their safety and effectiveness. Here are some best practices for selecting storage containers:

Chemical-resistant containers: Sanitizer chemicals should be stored in containers made of materials that are compatible with the specific chemical. For example, chlorine-based sanitizers should be stored in plastic containers made of high-density polyethylene (HDPE) or polyvinyl chloride (PVC).

Tightly sealed containers: To prevent evaporation and contamination, sanitizer chemicals should be stored in tightly sealed containers. This also helps minimize the risk of spills and accidents.

Proper labeling: All storage containers for sanitizer chemicals should be clearly labeled with the name of the chemical, hazard warnings, and handling instructions. This ensures that employees can easily identify and handle the chemicals safely.

Storage racks and shelving: Storing sanitizer chemicals on dedicated racks or shelving units helps keep them organized and prevents the risk of accidental spills or leaks. It also ensures that the chemicals are kept away from food and food contact surfaces.

Segregation and Separation

Proper segregation and separation of sanitizer chemicals from other substances is essential to prevent cross-contamination and reactions that could compromise their effectiveness. Here are some key practices for segregation and separation:

Separate storage areas: Sanitizer chemicals should be stored in designated areas away from food storage, preparation, and handling areas. This helps prevent accidental contact or contamination of food or food contact surfaces.

Separate storage for each type: Different types of sanitizer chemicals should be stored separately to prevent unintended chemical reactions. This also helps in the event of a spill or leak, as it limits the potential impact on other chemicals.

Avoid mixing: Under no circumstances should different sanitizer chemicals be mixed together, as this can lead to hazardous reactions and the formation of toxic fumes.

Proper ventilation: Adequate ventilation in the storage area helps dissipate any fumes or vapors from the sanitizer chemicals, preventing the buildup of noxious gases.

Employee Training and Awareness

Ensuring that employees are adequately trained in the proper handling and storage of sanitizer chemicals is crucial to maintaining a safe and compliant environment in a food establishment. Key aspects of employee training and awareness include:

Hazard communication: Employees should receive training on the hazards associated with sanitizer chemicals, including potential health effects and safe handling practices.

Storage procedures: Employees should be familiar with the specific storage requirements for each type of sanitizer chemical used in the food establishment. They should understand the importance of proper labeling, segregation, and separation.

Emergency response: Training should cover the procedures to follow in the event of a spill, leak, or exposure to sanitizer chemicals, including the use of personal protective equipment (PPE) and the steps to take to mitigate the situation.

Regular inspections: Employees should be trained to conduct regular inspections of the storage areas to ensure that sanitizer chemicals are stored correctly and that the storage containers are in good condition.


The proper storage of sanitizer chemicals in a food establishment is paramount for maintaining a safe and hygienic environment. By adhering to regulatory standards, implementing ideal storage conditions, selecting suitable storage containers, and ensuring proper segregation and separation, food establishments can ensure the effectiveness and safety of sanitizer chemicals. Equally important is the training and awareness of employees to handle and store sanitizer chemicals in a responsible manner. These practices not only contribute to food safety but also help food establishments comply with regulatory requirements and maintain a positive reputation in the industry.
