Section 437-002-0210 - Additional Oregon Rules for Compressed Air and Compressed Gas Equipment

(1) Air and Gas Compressors -- General:

(a) Workers shall not use compressed gases to clean clothing which is being worn nor shall it be intentionally directed at any other person;

NOTE: Use of compressed air for cleaning work and work areas is also prohibited except under special conditions. See OAR Chapter 437, Division 2/P, Hand and Portable Powered Tools and Other Hand-Held Equipment.

(b) Hose connections shall be securely made and maintained in safe working condition. Effective means shall be used to prevent hose from whipping.

(2) Piping Systems:

(a) All piping systems and their component parts which are installed to carry air, steam, or other material at more than atmospheric pressure shall be of adequate design and strength to safely withstand pressures to be placed upon them without the resulting stresses exceeding the allowable stress for the material used in their construction. The allowable stresses to be used shall be determined by referring to recognized standards for materials and design as developed by the American National Standards Institute;

(b) The only non-metallic pipe acceptable for pressure line service with gaseous substances is that which is recommended and listed by its manufacturer as designed for compressed air or gas service. PVC pipe can only be used for compressed air if it is buried or encased;

(c) All compressed air or gas piping systems which use plastic pipe must be "project specific"; that is, designed by a competent person to specifications suited for a particular application or project. Design and operational specifications and information must be kept with the system for as long as it is in use;

(d) Only a competent person(s) may install any compressed air or gas piping system described in subsections (b) and (c) of this section.

(3) High Temperature Piping:

(a) All steam and other high temperature pipe lines within seven feet of the floor or work platform or passageway shall be covered with non-combustible insulating material or otherwise protected against accidental contact with persons;

(b) Steam hose connections shall be securely made and maintained in safe working condition. Effective means shall be used to prevent hose from whipping.
