Piping, hazards

Institution of Chemical Engineers, Safer Piping —Hazard Workshop Module 012 (available as a training kit with a videotape, 105 35mm slides, a teaching guide, etc. by the IChemE). 

But, all of these obvious technical pipeline considerations are sometimes overh>oked, and many of the most infamous incidents have involved poor practices in piping design, in operations, or in piping maintenance systems. The American Insurance Association states Piping hazards are often underrated as compared to pressure vessels although the history of failures does not warrant this... . Piping systems should be located in. serviceable areas. They should be constructed in accordance with appropriate code requirements and inspected by appropriate means.. .. [20]...

Lead and Lead-Lined Steel Pipe Lead and lead-hned steel lipe have been essentially eliminated as piping materials owing to lealth hazards in fabrication and installation and to environmental objections. Lead has been replaced by suitable plastic, reinforced plastic, plastic-lined steel, or high-alloy materials. 

Piping Modifications One resiilt of the inspec tion of the sample locations is a list of sample locations that will require modifications. The mechanical department will be required to make these modifications before the unit test is run. It is likely that the locations that are not typically used will be plugged with debris. The plugs will have to be drilled out before the test begins. Drilling out plugs presents a safety hazard, and those involved must be aware of this and follow the plant safety protocols.
