CAUTION: Hand Controls
The environment in which hand controls are installed must not adversely affect the means of
actuation. Severe contamination or other environmental influences may cause slow response or false
On conditions of mechanical or ergonomic buttons. This may result in exposure to a hazard.
Two-Hand Control Safety Distance (Minimum Distance)
Both hand controls must be located far enough away from the nearest hazard point that the operator cannot reach the
hazard with a hand or other body part before the hazardous motion ceases. This is the “separation distance” (“safety
distance”), and may be calculated as follows.
WARNING: Location of Touch Button Controls
Hand controls must be mounted a safe distance from moving machine parts, as determined
by the appropriate standard. It must not be possible for the operator or other non-qualified persons
to relocate them. Failure to establish and maintain the required safety distance may result in
serious injury or death.
U.S. Applications
The Safety Distance formula, as provided in ANSI B11.19:
Part-Revolution Clutch Machinery (the machine and its controls allow the machine to stop motion during the
hazardous portion of the machine cycle)
