ReLiabiLity Flooring Descriptions to the sections on the PCAR form. 1. Description of nonconformity: Describe the problem. 2. Corrective (C)/Preventive (P): Indicate whether it’s a problem (corrective) or a potential problem (preventive). Can be both. 3. Reply requested by: Name of person who documented the problem. Reply by Date: Should be no later than one week from date of origin. Reply date isn’t the date by which the PCAR will be resolved. It’s the due date for documenting the actions to be taken (immediate, interim, root cause identification, action to preclude recurrence and remedial action). 4. Reply: Immediate action taken: What you are doing now to address the problem. Might not be applicable to every situation. Also referred to as a “quick fix.” Interim action: Temporary action – what you are going to do before you can correct the problem. Root cause: What caused the problem? This will take some investigation. Action to preclude recurrence: What you are going to do to prevent the problem from happening again. Remedial action: This is where you provide a solution to the nonconformity (problem). Lists specifics, i.e., dates, times resources. 5. Date for full compliance: List the date you will have the problem cleared. 6. Verification: Proposed action is complete? Yes or no: Person who investigated root cause verifies action taken. Is action taken effective? Yes or no: Lead auditor verifies action taken and documents the audit evidence. preclude recurrence of existing floor problems. Information developed during steps 1 through 3 are used in pursuing corrective actions. Other sources might include employee inputs and management observations and needs. After identifying the root cause of the problem and specifying the solution, focus on proper surface preparation. It must be sound, dry and clean before applying any product to ensure optimum substrate adhesion. The preparation methods depend on the type of floor coating or resurfacing system being applied. Choices include: • Vacuum shot blasting: The most popular method, it’s 98% dust-free, thus environmentally friendly. • Scarification: Aggressive, for severely eroded floors. • Milling: Removes badly damaged concrete. • Grinding: Removes the skin of a fresh concrete substrate or old paint layers. • Chemical preparation: Typically, acid etching. The function and resistance of a floor coating provides a variety of solutions depending on the resistance required. Take into account the floor coating properties once the substrate and usage have been analyzed and documented. An important floor coating property is its abrasion resistance. Generally accepted classifications for usage are: • Light traffic: Pedestrian and hand truck usage. • Medium traffic: Fork-lift trucks, wooden pallets, crates. • Heavy traffic: wheeled machinery and equipment, heavy-duty fork-lift trucks and metal pallets, crates. Another important property is chemical resistance. Industrial floors can be subject to chemical attack from acids, oxidizers, alkalis, salts, organic compounds, dyes, solvents of all sorts, fuels, oils and greases. The manufacturer should encourage you to consider the future (short-term versus long-term occupancy, lease or own, changing conditions, crucial factors overlooked, spinoff effects and side-effects). Once the product and application are defined, the manufacturer should furnish a Material Specification Guideline to document the project scope, current floor conditions, problem diagnosis, the root cause and the solution that prevents recurrence. No two concrete floors are alike. Don’t be tempted into comparing and expecting the same solution and outcome as what appears to be a similar-looking floor elsewhere or in a different industry. Follow-up verification The manufacturer should follow up after project completion to verify its effectiveness and to ensure the result meets your needs and satisfaction. All too often, after the floor resurfacing system is installed, end users forget the product name and the company that installed it. Look for a manufacturer that remains with you throughout the project. You want one that partners with you to provide ongoing support and technical assistance that maintains the condition of your flooring and prevents potential problems in the future.
