Originally published in January, 1990, PMPA’s Safety & Health Bulletin #192 acquaints you with Lockout/Tagout rules and regulations required by OSHA’s Control of Hazardous Energy Sources Standard, which became effective on January 2, 1990.

Certification of PPE Hazard Assessment Is Required Under 29 CFR 1910.132
To certify PPE hazard analysis required under 29 CFR 1910.132, a PPE (Personal Protective Equipment Assessment) must be completed.
We are providing forms for use to identify hazards and the PPE required. We have reviewed a number of forms and formats and believe that these forms will help you make thorough and effective assessments. See Link below.
A job specific analysis can be undertaken, however many of our shops have reported success using a “Shop Operations” approach to identify hazards that all personnel in their shop face.
Here are some tips for your assessment based on my shop visits, review of OSHA citations for our industry, training and experience.
One final note: It isn’t just metal chips, burrs, metal banding, or tools that can cut skin, I once had to transport an employee to the hospital for stitches from a paper cut from the paper we used to wrap steel bundles- 4” gash on forearm, job became long sleeve…

The sample SPCC (Spill Prevention, Control and Countermeasure) Plan was released in January, 1997 by EPA Region V headquarters as a guide to help companies develop their own SPCC plans.

Take a walk through “Anyshop USA” and observe the actions being taken to serve the customer. Rarely will you see someone with an open work instruction book reading about how his or her particular task is to be completed. The vast majority of shop employees know what it takes to ensure that a high-quality product arrives at the customer’s dock on time. They have been instructed in specific tasks and they follow those instructions.
In the Precision Machined Products Industry, there are never-ending discussions concerning
definitions of different hourly measures as well as utilization measures based on these hours.
To assist in getting the thinking consistent throughout the Precision Machined Products Industry
in regard to hour definitions and utilization, this document includes the following:
At the 1997 PMPA Management Update Conference, PMPA members Jim Heller and Peter Rosenkrands, of A. B. Heller Inc., Milford, MI, and Rick Dawes, Enoch Mfg. Co., Clackamas, OR, unveiled spreadsheet applications designed to assist precision machined products manufacturers in making complex capital expenditure decisions.
Project Justification Spreadsheet, created by Jim Heller and Peter Rosenkrands, is an MS Excel workbook consisting of two worksheets which examine cash payback and net present value calculations for two different machine tool purchase options. A third worksheet provides a set of tables and constants used to support the cash payback calculation. You can also download a Readme file which provides an explanation of the input data and calculated data for each of these worksheets.
Click below to download another sample workbook which uses the same methodology to compare payback and net present value of two other machine tools.
You can also download Capital Expenditure Comparison Chart, developed by Rick Dawes, which uses the techniques pioneered by these three members to investigate the optimum payback to a company from a number of different types of investments. The data in this spreadsheet is fictitious and intended for demonstration purposes only. Enter your own data in this spreadsheet (numbers in red) for answers to questions such as “If I had x dollars to spend, would I be better off buying a good CNC machine, or the best CNC machine, or a copier for the office, or a new fork lift?”
Disclaimer
These spreadsheets have been written to assist the developers in their internal capital expenditure decision making. The developers have been kind enough to make them available to the entire membership. PMPA and the developers offer no warranty for the use of these products, nor will they be able to offer any support for their use. These spreadsheets are tools to assist in the decision making process, and members who use them do so at their own risk.

Basically, knurling is broad tolerance cold forming or displacement of material. It is an inexpensive way to increase the diameter of a part without adding much cost (if any). It is not a close tolerance feature. Questions by NSMPA members have prompted us to look at the “normal” and/or standard ways to measure knurls.
