Hi irheavyd,
Construction:
The particular type of structure, materials, etc. that something has
Maintenance:
The activity of keeping a building, equipment, vehicle, etc. in good condition by checking it regularly and repairing it when necessary
As you haven’t posted in a food safety standard topic I’m going to use SQF to provide examples. If we look at construction requirements in the SQF Food Safety Code Section 11.1 Site Location and Premises 11.1.2 Building Materials:
11.1.2.1 - Floors shall be constructed of smooth, dense, impact-resistant material that can be effectively graded, drained, impervious to liquid, and easily cleaned.
11.1.2.2 - Drains shall be constructed and located so they can be easily cleaned and not present a hazard.
11.1.2.4 - Walls, partitions, ceilings, and doors shall be of durable construction.
11.1.2.4 - Ducting, conduit, and pipes that convey ingredients, products, or services, such as steam or water, shall be designed and constructed to prevent the contamination of food, ingredients, and food contact surfaces and allow ease of cleaning.
11.1.2.6 - Pipes ….. constructed
11.1.2.7 - Doors, hatches, and windows and their frames in food processing, handling, or storage areas shall be of a material and construction that meets the same functional requirements as for internal walls and partitions. Doors and hatches shall be of solid construction, and windows shall be made of shatterproof glass or similar material.
11.1.2.8 - Product shall be processed and handled in areas that are fitted with a ceiling or other acceptable structure that is constructed and maintained to prevent the contamination of products. Drop ceilings, where present, shall be constructed to enable monitoring for pest activity, facilitate cleaning, and provide access to utilities.
11.1.2.9 - Stairs, catwalks, and platforms in food processing and handling areas shall be designed and constructed so they do not present a product-contamination risk and with no open grates directly above exposed food product surfaces. They shall be kept clean (refer to 11.2.5).
Also there are clauses:
11.1.7 Equipment and Utensils
11.1.7.3 - Equipment storage rooms shall be designed and constructed to allow for the hygienic and efficient storage of equipment and containers.
11.3.2 Handwashing
11.3.2.3 Handwashing stations shall be constructed of stainless steel or similar non-corrosive material and at a minimum supplied with:
11.5 Water, Ice, and Air Supply
11.5.1.6 Where water is stored on-site, storage facilities shall be adequately designed, constructed, and routinely cleaned to prevent contamination.
11.5.4 Ice Supply
11.5.4.3 - Ice rooms and receptacles shall be constructed of materials as outlined in element 11.1.2 and designed to minimize contamination of the ice during storage, retrieval, and distribution.
11.6.2 Cold Storage, Freezing, and Chilling of Foods
11.6.2.1 The site shall provide confirmation of the effective operational performance of freezing, chilling, and cold storage facilities. Chillers, blast freezers, and cold storage rooms shall be designed and constructed to allow for the hygienic and efficient refrigeration of food and be easily accessible for inspection and cleaning.
Maintenance - Not so relevant alternative definitions:
The process of keeping or continuing something
The process of making sure that something continues in the same way or at the same level
Regular payments that a person must make by law in order to support their child or previous marriage partner, for example after a divorce
If we look at requirements in the SQF Food Safety Code Section 11.2.1 Repairs and Maintenance
11.2.1.1 The methods and responsibility for the maintenance and repair of plant, equipment, and buildings shall be documented, planned, and implemented in a manner that minimizes the risk of product, packaging, or equipment contamination.
11.2.1.2 Routine maintenance of plant and equipment in any food processing, handling, or storage areas shall be performed according to a maintenance control schedule and recorded.
The maintenance schedule shall be prepared to include buildings, equipment, and other areas of the premises critical to the maintenance of product safety.
11.2.1.3 Failures of plant and equipment in any food processing, handling, or storage areas shall be documented and reviewed, and their repair(s) incorporated into the maintenance control schedule.
11.2.1.4 Site supervisors shall be notified when maintenance or repairs are to be undertaken in any processing, handling, or storage areas.
11.2.1.5 The maintenance supervisor and the site supervisor shall be informed if any repairs or maintenance activities pose a potential threat to product safety (e.g., pieces of electrical wire, damaged light fittings, and loose overhead fittings). When possible, maintenance is to be conducted outside operating times.
11.2.1.6 Temporary repairs, where required, shall not pose a food safety risk and shall be included in routine inspections (refer to 2.5.4.3) and the cleaning program. There shall be a plan in place to address the completion of temporary repairs to ensure they do not become permanent solutions.
11.2.1.7 Food contact equipment and equipment located over food contact equipment shall be lubricated with food-grade lubricant, and its use shall be controlled to minimize the contamination of the product.
11.2.1.8 Paint used in a food handling or processing area shall be suitable for use, in good condition, and not be used on any product contact surfaces.
Also, your Hygiene/Listeria SOP should reflect this GMP requirement in the SQF Code Section 11.2.2 Maintenance Staff and Contractors which is generally required across all food safety standards:
11.2.2.3 Maintenance staff and contractors shall remove all tools and debris from any maintenance activity once it has been completed, and inform the area supervisor and maintenance supervisor, so appropriate hygiene and sanitation can be conducted and a pre-operational inspection completed prior to the restarting of site operations.
Kind regards,
Tony
