New safety standards released for plastics machinery

The Plastics Industry Trade Association and the American National Standards Institute (ANSI) recently published two recently revised and approved American National Standards on plastics machinery safety. ANSI/SPI B151.20 - 2013 Safety Requirements for Plastics Sheet Production Machinery, and ANSI/SPI B151.27 - 2013 Safety Requirements for the Integration of Robots with Injection Molding Machines, both of which address detailed safety requirements for the specific machine or group of machines.

New safety standards released for plastics machinery

Both standards represent significant and substantive changes from the previous editions and both are considered Type-C standards according to the ISO Type A-B-C standard level structure. ISO Type A standards (basis standards) provide basic concepts, principles for design, and general aspects that can be applied to machinery. ISO Type B (generic safety standards) address one or more safety aspects or one or more types of safeguards that can be used across a range of machinery.

B151.20 specifies the requirements for the manufacture, care, and use of plastics sheet production machinery to minimize hazards to personnel associated with machine activity. The newly revised standard includes updates to reflect changes in technology and provides additional explanatory materials, illustrations and definitions.

B151.27 addresses the integration, care, and use of robots used with injection molding machines to minimize hazards to personnel associated with robot and machine activity. Complicated by the variety and sizes of machines and robots manufactured, the standard approaches the problem of integration safety from three different areas: to eliminate recognized hazards by design criteria, establish standard approaches to design, and safeguard the point of operation to protect the operator from recognized hazards.

To assist in the interpretation of these requirements in both standards, responsibilities have been assigned to the supplier, the remanufacturer, the modifier and the user.

Other SPI/ANSI Standards address the safety requirements for injection molding machines, extrusion machines and blowmolding machines.
