Safety Precautions For Open Roller Gates; Safety Precautions For Grill Type Gates - Chamberlain LiftMaster Professional SL540 Manual

Injuries occur when people get their hands or feet caught between the top or bottom of the gate and the gate roller. This
potential pinch-point should be guarded against at all times. Enclosed style gate tracks are available for refitting of these
rollers from many fence suppliers. Also, roller guards are available for installing over the rollers.
UL325 requires that, when used, contact sensors shall be located at the leading edge, trailing edge, and post-mounted both
inside and outside of a vehicular horizontal slide gate. Non-contact sensors such as photo eyes must protect during both
open and close gate cycles.

Injuries occur when people put their hands and arms through openings in the grill while the gate is operating. They cannot
retract their arm and it gets caught between the moving gate grill and the stationary fence post or fence. This potential
hazard can be averted by placing a 4' screen mesh on the gate to prevent access through openings anywhere the gate may
travel. See Safety Brochure for details.
