are correctly connected to earth ground with an electrical
conductor that complies with current codes. Install in accordance
with national and local codes, which apply.
When you have completed the repair or maintenance procedure,
check your work, remove your tools, rigging, and handling
equipment.
Do not restore power to the conveying system until all persons are
clear of the area. DO NOT start and run the conveying system
until you are sure all parts are functioning correctly.
BEFORE you turn the conveying system over to the operator for
production, verify all system enclosure panels, guards and safety
devices are in place and functioning properly.
2-8 Safety
2-8-1 Description and Objectives
This section includes information on safety devices and procedures that are
inherent to the Vacuum/Pressure Conveying System. This manual is not
intended to supersede or alter safety standards established by the user of this
equipment. Instead, the material contained in this section is recommended to
supplement these procedures in order to provide a safer working environment.
At the completion of this section, the operator and maintenance personnel will
be able to:
• Identify and locate specific safety devices.
• Understand the proper use of the safety devices provided.
• Describe the function of the safety devices.
2-8-2 Safety Circuit Standards
Safety circuits used in industrial systems protect the operator and maintenance
personnel from dangerous energy. They also provide a means of locking out or
isolating the energy for servicing equipment.
Various agencies have contributed to the establishment of safety standards that
apply to the design and the manufacture of automated equipment. The
Occupational Safety and Health Administration (OSHA) and the Joint
Industrial Council (JIC) are just a few of the organizations that have joined
with the plastics industry to develop safety standards.
