Who Should Attend the Course

Anyone that is required to manage and/or evaluate the slip resistance of surfaces including property managers, risk/loss control, Forensic Engineers, Materials Engineers, and Walkway Auditors. Graduates of the course receive a discounted rental rate and a $250 coupon towards purchase of GS-1. We will be supplying GS-1s for course (average 2-3 people per GS-1) to ensure maximum hands-on use.

Note: Limiting course to 10 people to maximize hands-on use of GS-1.

GS-1 Operator Certificate Course Level 1 and II

Measuring the Static and Dynamic Coefficients of Friction of a surface requires use of a tribometer like the GS-1. The GS-1 can be used on most surfaces to measure wet and dry static and dynamic coefficients of friction.

In this 8.0-hour in-person Johnson Forensic Labs-approved course you’ll be trained how to use the GS-1 to measure wet and dry static and dynamic coefficients of friction.

The course explains the science of slip resistance, the physics of coefficient of friction (COF), and the difference between wet and dry static coefficients of friction (SCOF, DCOF). Proper preparation and calibration of the GS-1 is essential to measuring SCOF and DCOF. The B101.1 and B101.3 procedures to measure SCOF and DCOF are explained and demonstrated.

The in-person course provides hands-on training to properly use the GS-1. Further study is required to assess slip resistance and provide walkway safety services.

How You Will Benefit
- Understand slip resistance
- Understand the physics of coefficient of friction and the difference between SCOF and DCOF
- Learn the proper procedures to prepare and calibrate the GS-1 prior to use
- Learn how to measure wet static and dynamic coefficients of friction following the B101.1 and B01.3 procedures
- Identify resources available to aid in further study of walkway safety and tribometry
