Floor Flatness and Floor Levelness can be critical to the safety of people and equipment, especially in areas with high foot and equipment traffic. Imagine walking on a rough, uneven sidewalk. You might stub your toe, scuff your shoes, or trip and fall. The same is true on a larger scale for concrete floors in industrial structures. When personnel are working on rough, uneven floors, workers might hurt themselves, equipment takes on unnecessary wear, and dangerous accidents become far more likely.
Warehouses are one example where the quality of flooring can have a significant effect on safety and productivity. Having flat, level floors allows lift trucks to operate at higher maximum speeds, reduces potential for damage to stock, and creates a smoother environment to reduce wear on lift trucks and similar equipment. Well-made floors also help reduce health and safety risks such as driver fatigue or tilting equipment, resulting in falling machinery or products.
Both Floor Flatness, denoted by an FF number, and Floor Levelness, denoted by an FL number, are evaluated through regulated procedures, and compared to standard allowances to determine if variations are at an acceptable level.
Floor Flatness is the measure of how bumpy or smooth the finished surface of a floor is. The flatness is a statistical measurement of how wavy or bumpy a concrete floor is. Individual measurements are taken at points every twelve inches along a line, and the differences between each adjacent point are calculated, along with the mean and standard deviations of the differences. A bumpy or uneven floor can result in injury to personnel, anything from a stubbed toe to a dangerous fall. It can also result in damage to equipment or damage to product from jarring motions created by the uneven floor. For these reasons it is critically important to ensure that floor flatness is at an acceptable level.
Floor Levelness is the measure of the inclination of the floor compared to its design inclination. The levelness is measured by using the difference in elevation between two points far apart. It is critical to ensure that floors are level within reasonable variation, especially in situations involving tall equipment and narrow aisles. Even a slight variation in floor levelness could result in tall equipment losing its balance or colliding with shelves in a narrow aisle, potentially causing harm to personnel or damage to products and equipment.
There are detailed standard procedures for these evaluations to help ensure the safety of personnel, equipment, and products. These testing procedures can help prevent hefty lawsuits or expenses due to equipment and product loss.
Encorus Group offers high quality testing services for floors, as well as many other aspects of construction and industry. If your construction site has floors that require flatness and levelness testing, contact Jeremy Lake at (716) 592-3980 ext. 133, or email@example.com.
