Chemical Safety and the Master Cleaning Schedule
- Identify safe chemical handling, labeling, storage, and spill response procedures in compliance with OSHA standards and the FDA Food Code.
- Develop and structure a comprehensive master cleaning schedule detailing what, who, when, and how every surface and piece of equipment is cleaned.
- Apply active managerial control by training staff, monitoring cleaning and sanitation tasks, taking corrective actions, and maintaining necessary records.
Chemical Selection, Safety Data Sheets, and Safe Handling
Chemicals are essential for maintaining a sanitary food establishment, but they present severe physical and chemical hazards if handled improperly. Food service managers are responsible for obtaining chemicals suitable for their intended food-service use from reliable suppliers and verifying their labels and any applicable approvals. Managers must select chemicals that comply with applicable labeling rules, Food Code standards, and local regulatory-authority requirements. While managers must confirm compliance, chemicals do not all require individual regulatory approval, and EPA registration is not a universal requirement for every permitted sanitizing method. However, food-contact-surface sanitizers must meet applicable Food Code and EPA requirements, and staff must always follow the manufacturer's label directions.
Under OSHA's Hazard Communication Standard, employers must have an SDS readily accessible during each work shift for each hazardous chemical covered by the standard that they use; limited exemptions include consumer products used with no greater exposure than ordinary consumer use. Safety Data Sheets contain critical safety information, including chemical hazards, safe handling procedures, required personal protective equipment (PPE), and first-aid measures. Managers must ensure that Safety Data Sheets are readily accessible to all employees in the facility at all times during their shifts. Employers must provide OSHA-required hazard communication training; managers should ensure affected staff know how to access and use Safety Data Sheets (SDSs) before working with hazardous chemicals and during an emergency.
Safe chemical use requires strict adherence to manufacturer instructions. Staff must never mix chemicals together unless specifically directed to do so by the manufacturer label, as combining incompatible chemicals can release deadly gases. Managers must train employees to follow directions precisely regarding chemical dilution ratios, contact times, and water temperatures. Where machinery contains gears or bearings, managers must verify that any lubricant used meets requirements for incidental food contact if it could contact food or food-contact surfaces. Additionally, managers must verify that automatic chemical dispensers deliver the required concentrations using appropriate test devices, arranging for prompt calibration or repair when dispensers fail to meter chemicals accurately.
| Container Type | Labeling Requirements | Operational Rules and Exceptions |
|---|---|---|
| Original Manufacturer Container | Must keep the original manufacturer label intact, complete, and legible. | Staff must follow all hazard warnings and applicable use directions printed on the label. Keep chemicals in these containers whenever possible to prevent accidental misuse. |
| Working Container (Transferred Chemical) | Must be clearly labeled with the common name of the chemical. | OSHA provides a limited immediate-use exception for portable containers, but this does not override applicable food-code labeling requirements. Working containers of cleaners and sanitizers must always show the common name. |
Common mistakes
- Failing to label a working container of cleaner or sanitizer because an employee intends to use it immediately, overlooking that the Food Code requires common-name labeling regardless of OSHA's portable container exception.
- Disposing of dirty mop water into toilets, urinals, handwashing sinks, or warewashing sinks instead of using the designated service sink or curbed cleaning unit.
- Storing toxic chemicals or employee personal medications on shelves directly above food-contact surfaces, prep lines, or clean utensils.
- Mixing different cleaning chemicals together, which violates manufacturer instructions and can generate lethal gases.
Key points
- For hazardous chemicals covered by OSHA's Hazard Communication Standard, managers must ensure SDSs are readily accessible during each work shift and that affected employees receive required hazard communication training, including how to access and use SDS information.
- Chemicals must be obtained from reliable suppliers, used according to manufacturer instructions, and kept in labeled containers; working containers must display the common name.
- Store poisonous or toxic chemicals so they cannot contaminate food or clean items, and do not store them above those items except for cleaners and sanitizers stored safely in warewashing areas; store employee medicines and first-aid supplies so they cannot cause contamination.
- Mop water must be discarded only into a designated service sink or curbed cleaning facility, and cleaning tools must be air-dried and stored away from food-contact items.
- Chemical spills require immediate isolation, reporting, PPE use, SDS reference, and assistance from emergency services or professional responders for severe hazards.
- A master cleaning schedule details what to clean, who cleans it, when to clean it, and how to disassemble, clean, sanitize, and reassemble it safely.
- Active managerial control includes training staff, providing tools, verifying sanitizer concentrations as required, monitoring cleaning work, correcting problems, and updating procedures; managers should use cleaning logs when useful or required by state or local rules.
