How safe is your kitchen floor?


Commercial kitchens can be a dangerous place; contaminants range from greasy water, milk and oil to food particles and flour. Staff tend to be very busy and it’s often not possible to clean as they go. It’s not simply spillages either; hot oil evaporates into the air, cools and settles on the floor, making it hard to see and a constant hazard. The contaminants found in a kitchen are often more dense than water or, in the case of food particles, dry rather than wet. This prevents the foot making contact with the floor and increases the risk of slipping.

A safety floor that performs well in a standard Pendulum or Ramp Test, which is also commonly used, may not cut the mustard when it comes to a real working kitchen with real and varied contaminants, putting staff at risk.

The Ramp Test results in R9-R13 values which are based on the angle at which a person slips while walking on a motor-oil covered ramp. We quote R values for our products because some of our customers are used to working with them but we don’t believe this test gives a clear enough indication of slip resistance. Starting at a high number, an R9 value appears as though it offers good slip resistance but it actually indicates the least slip resistance. In short, it’s confusing.

Altro Stronghold 30, which measures PTV ≥55, was developed specifically for areas where grease, oils and fats may be present, such as kitchens, canteens and food preparation areas. We decided that it wasn’t enough to use the standard Pendulum Test, which uses water, nor the Ramp Test, which uses motor oil, and carried out our own tests using contaminants that would actually be found in kitchens. *

The results show that flooring with a Ramp Test value of less than R12 cannot prevent slips when vegetable oil or greasy water is present; the risk of slipping is reduced to one in 20, even when the Pendulum Test result is ≥36.
