WARNING: Not a Stand-Alone Safeguarding Device
This Banner device is not a stand-alone point-of-operation guarding device, as defined by
OSHA regulations. It is necessary to install point-of-operation guarding devices, such as safety light
screens and/or hard guards, to protect personnel from hazardous machinery. Failure to install point-
of-operation guards on hazardous machinery can result in a dangerous condition which could
lead to serious injury or death.
