Food Safety Starts with StopLight™! CRC developed the StopLight™ Food Safety Program in response to a growing need in the food industry to minimize the risk of food contamination from maintenance chemicals across all food processing areas. The StopLight™ Program helps insure proper product usage, maximum regulatory compliance, and minimum risk and cost. CRC also introduced the Perma-Lock® actuator on our H1 aerosol lubricants. Perma-Lock® is a 2-way actuator that features a flip straw that locks into place. Perma-Lock® will not detach, safeguarding against costly recalls. Perma-Lock® - You Just Can't Lose®!
