R Ratings

German Ramp Test: R Ratings

Problems of R Numbers and Ramp tests

Measuring the R number of a sample of floor in a lab is relatively easy, if quite expensive. However, a lab test tells only a part of the story and may be misleading. It is easy to be misled by a lab test value that does not reflect how the floor will behave when laid. A flooring supplier may make false claims relating to the floor R number rating 9either by accident or design), and the actual value of slip risk once the floor is laid may differ from the “factory tested” R number.

Another common problem, according to the UK HSE is interpreting the data produced. Each ‘R’ value contains a range of possible, results making it difficult to ascertain how slippery a floor is. It is suggested that floors need a PTV of 70 or better to match R13, in fact we know that PTV of 36+ is low risk and PTV of 40+ is considered perfectly safe for pedestrian walking.

Many people assume R9 is good, but many floors that gain R9 certification are not safe for use in wet conditions

Is someone in your business accountable for slip injuries?

Historically, few businesses have trained staff to understand slip risk. A few H&S Managers may see presentations “talking ” about slip risk and “hydrodynamic squeeze film” but few appreciate how to measure or managing slip risk. Teaching staff will reduce accidents, reduce injuries and reduce claims. It will save you money in the short-term and it will reduce your risk of longer term problems caused by poor floors or poor cleaning.

Slip Prevention Workshops

We provide slip prevention training workshops for H&S managers, EHO’s, cleaning staff, architects and for anyone involved in specifying or managing floor safety. These interactive an informative workshops include everything you need to know to keep floors safe. 

New - Certificate in Slip Risk Asessment

We are pleased to announce that we now offer certificate courses in slip risk assessment. You can train your staff how to measure and manage slip risk in your business. We tailor the courses to the specifics of your business.

Staff Involvement & Training

The principles of sustainability and safety demand that floors will provide adequate slip resistance at the end of an economically reasonable working life.

Slip prevention has been the “Cinderella” of health and safety. H&S manager in every business need a slip prevention policy and management systems that align with procurement, cleaning and flooring maintenance. Each floor area should merit its own slip prevention compliance plan.

Small changes to the cleaning schedule, cleaning methods or cleaning materials can make a big difference to overall slip risk. Green cleaning can be safe. Property owners and Facility Managers must educate staff to fully understand and manage slip risks.
