Choices for these safeguarding methods may include one or more of the following:
• chip and coolant shields
• guards (fixed, movable, and/or interlocked)
• presence-sensing devices
• two-hand control
• awareness barriers and devices
Correctly applied chip/coolant shields meet OSHA’s minimum requirements for point-of-operation protection for operators of manually operated milling machines.
Automated (CNC) mills—machining centers— require interlocked guards at the point of operation.
Rockford Systems encourages all employers to exceed minimum requirements and abide by the best safety practices found in ANSI B11.8-2011 (R2008) for drilling, milling, and boring machines, and ANSI B11.23-2002 (R2007) for machining centers. The key to employee safety is to observe best safety practices at all times.
