Hello, I'm John Gucking from MPSA Safety, and today I'm going to tell you how to use a Gotcha Stick and why it's essential for machine safety. But, before diving in, let's review the goal of any Gotcha Stick.
The primary purpose of a Gotcha Stick is simple: to test barrier guard openings near machine hazards and determine whether or not the guard openings are compliant with OSHA and ANSI machine safety standards.
A Guard Opening Scale, AKA a "Gotcha Stick," is a tool used to ensure machine barrier openings are compliant with up-to-date machine safety standards.
The Gotcha Stick physically tests the measurements between guard openings and machine hazards, quickly determining whether or not the guard openings are safety standard compliant. Testing machine barrier openings with a Gotcha Stick helps ensure the barrier guarding is at a safe distance away from the hazard.

Since the early 1940s, people’s assumptions about machine safety haven’t always been correct. Many people once assumed that as long as a machine had some guarding, the staff was safe from machine hazards. That was swiftly debunked when teams working with presses and lathes without proper machine safety guarding soon faced many injuries, amputations, and even deaths.
So, in 1948 Liberty Mutal Insurance collaborated with the Writing Committee for the ANSI B11.1 Safety Standard on Mechanical Power Presses to engineer a stair-step-shaped measurement tool to determine the minimum safe distance between a guard opening's distance to the nearest point-of-operation hazard. For the last 70 years, the Gotcha Stick has proven to be the most effective way of ensuring barrier guard openings will not allow a dangerous zone to be accessed.
Today, there are two types of modern Gotcha Sticks. The OSHA Compliance Gotcha Stick and the ANSI scale Gotcha Stick. These separate tools test for conformance to the measurements set forth by OSHA regulations from 1971 and by ANSI and CSA standards. Check out our Standards & Regulations page for up-to-date safety standards.

A Gotcha Stick mimics the human hand and forearm to ensure hazards are at a minimum safe distance. Remember, though, that the Gotcha Stick is a two-dimensional representation of three-dimensional human body parts. Thus, engineers must use proper techniques to ensure barrier guards are measured at a minimum safe distance from the hazard.
You'll first attempt to touch the Hazard with the Gotcha Stick by putting the smaller, scaled side of the stick into the guarding that surrounds the hazard you wish to test.
If designed correctly, the barrier guard will stop the small end of the Gotcha Stick from touching the hazard area. However, if the Gotcha Stick touches the hazard, the machine guards are too close to the hazard, which means your machine guarding is not compliant and someone could potentially be injured.
You can fix the unsafe machine guarding in one of two ways; move the guard further away from the hazard, make the adjustable guard opening smaller, or a combination of the two solutions.
Lastly, when using the Gotcha Stick, keep in mind that your machine guard openings size determines the minimum safe distance from a hazard. In addition, different barrier openings have different minimum safe distance requirements and OSHA and ANSI standards. For more information on how to use the Gotcha Stick, review the minimum safe distance measurements for known gap sizes printed on the backside of the tool.
