Beryllium Standard Final Rule: Do You Machine Beryllium?

Posted August 07, 2018 1:17 PM by Milo

The 2017 final rule established new permissible exposure limits.

It also included provisions to protect employees from exposure to Beryllium, such as

  • requirements for exposure assessment,
  • methods for controlling exposure,
  • respiratory protection,
  • personal protective clothing and equipment,
  • housekeeping,
  • medical surveillance,
  • hazard communication,
  • recordkeeping

Do you machine Beryllium in your shop?

Have you evaluated your compliance to the above 8 points of regulatory concern?

Do you know the key regulatory enforcement and compliance dates?

Beryllium Copper is not only used in electrical applications!

If your shop machines any of the following Beryllium Copper grades, it does apply to you:

Beryllium Coppers C17000, C17200, C17300, C17410, C17500, C17510

The rule applies to occupational exposure to Beryllium in all forms, compounds, and mixtures in
general industry, construction, and shipyards.

  • Employers that are covered under the rule must use engineering and work practice controls to
    keep exposures at or below the PELs.
  • Engineering controls include using process isolation, ventilated enclosures, or local
    exhaust ventilation to keep beryllium from being dispersed throughout a work area.
  • Examples of work practices to control beryllium exposures include keeping surfaces
    clean by using a HEPA-filtered vacuum or by wetting down dust before sweeping it up.
  • If engineering and work practice controls cannot keep exposures at or below the PEL,
    employers must provide respiratory protection to affected employees.

PMPA is providing members with sensemaking regarding this final rule, compliance dates and strategies, and helpful links to better understand their responsibilities.

7 Industry Trends to Think About, New Technology Isn’t One of Them

Posted December 26, 2017 10:30 AM by Milo
Pathfinder Tags: machining manufacturing trends

You may be surprised that Technology as a stand alone item is not one of them.

Our future is not about shinier flying saucers.

We will master and implement whatever technologies are developed.

But our future is being impacted by these 7 items today:

  1. Loss of experienced workers taking tribal and craftsman knowledge out of our shops.
  2. Lower average wages as experienced workers with seniority leave and younger workers start at trainee wages, making it difficult to attract talent with facts about “increasing wages”- even though they are.
  3. Training growing in percent of spend as many shops are unable to purchase new technology to quote new work because they do not have trained workforce.
  4. More and more jobs being quoted out of more challenging, non free machining materials;
  5. A bit of relief from new regulations, but more uncertainty as Washington turns to trade issues which can impact availability and cost of imported materials, and tooling, as well as impact the exports of finished goods that contain our parts.
  6. Increasing demands for certification of production to a wide variety of customer demanded requirements regardless of legal obligations- Conflict Minerals, REACH, RoHS, Animal- Free; Ca. Prop 65. Etc.
  7. Possibility of an “Association Healthcare Insurance solution” in 2019 or beyond.

What do you see as the trends shaping our company and industry future?

Please don’t say technology- as Humans, we’ve been successfully implementing new technologies for quite some time.

Craft Advice for Machinists: How Good Can You Get?

Posted December 21, 2017 10:30 AM by Milo

Gary Chynne uses his skills with the longbow to explain and demonstrate the fundamentals of mastery by having and following the process in “Guy Language.”

How good can you get?

At 3:10 into this video, he summarizes his lesson: ” So how good can you get? If you know all your steps- you take your front step, your back step. Get your head, get your bow at 45 degrees, get it back to your anchor, relax your arm. If you can follow those steps and get bulls-eyes, THEN DO IT!

“Do not short draw. Do not overdraw. Do not draw to the right of your anchor. Do not draw to the left of your anchor. Don’t let your bow waver around. Don’t let it wiggle. If its supposed to be 45, make it 45.

“That’s how you’re going to hit the target. So its just a matter- once you know how to shoot- how good can you get- at taking the steps to shoot properly?”

Probably the best advice you’ll ever get about machining as well. Follow the process. Be true to the process. Don’t take shortcuts or deviate from your known process.

His follow up is TRUTH as well

Anyhow, it’s kind of a blast, and its kind of a bit harder than you would wish, sometimes. Anyhow, when you do that stuff, you start to hit the target.”

Or, as one of the commenter’s posted:

Don’t just practice until you can get it right. Practice until you never get it wrong.

I think that this is probably some of the best machinist advice I’ve run across. What about you?

Top Ten OSHA Violations in 2017

Posted December 19, 2017 10:30 AM by Milo
Pathfinder Tags: osha safety top ten

Deputy Director of OSHA’s Directorate of Enforcement Programs Patrick Kapust presented the agency’s preliminary list at the National Safety Congress and Expo on September 26.

Powered Industrial trucks 1910.178 makes the TOP TEN again in 2017

Here are the Top Ten, along with the number of citations.

  1. Fall Protection – General Requirements (1926.501) – 6,072
  2. Hazard Communication (1910.1200) – 4,176
  3. Scaffolding (1926.451) – 3,288
  4. Respirator Protection (1910.134) – 3,097
  5. Lockout/Tagout (1910.147) – 2,877
  6. Ladders (1926.1053) – 2,241
  7. Powered Industrial Trucks (1910.178) – 2,162
  8. Machine Guarding (1910.212) – 1,933
  9. Fall Protection – Training Requirements (1926.503) – 1,523
  10. Electrical – Wiring Methods (1910.305) – 1,405

If you are just now reviewing your OSHA training performance, these standards would be a great place to start.

The items numbered 1910 are General Industry, those numbered 1926 are Construction.

Foaming: Why Base Oil Differences Matter In Your Shop.

Posted December 15, 2017 10:00 AM by Milo
Pathfinder Tags: CNC manufacturing oil

You don’t need a degree in Organic Chemistry to understand the differences in your shops’ metalcutting fluid base oils and what they mean to you.


Synthetic base oils clearly are less prone to foaming than mineral oil base stocks.

A recent discussion on PMPA’s member’s only Technical Listserve centered around the issue of foaming in our machines and its relation to the type of cutting oil selected for use in our CNC and Swiss machines.

John Wiley, Business Development Manager for PMPA Technical Member Qualichem, Inc. contributed a nice piece of sensemaking regarding the role that the selection of base oil plays in the foaming we encounter on the machine.

“In this picture you can clearly see the differences in a base oil’s tendency to foam. These are pure base oils, nothing added. Poly Alpha Olefin (PAO) and Gas To Liquid (GTL) synthetics are identical, while the two mineral oils foam considerably more than the synthetic stocks. If you are a shop that has yet to experiment with new cutting oil technology, now is the time. The benefits are firmly within your budgets. If you are doing medical work, the GTL oils are ideal. If you are running lights out operations, the GTL are ideal. If you want a cleaner shop, cleaner machines and cleaner parts, GTL is ideal.”

John went on to describe the scenarios where PAO’s and GTL’s would be expected to be the best choice for certain operations (like high pressure pumps) and applications, as well as compared the economics of PAO’s and GTL’s. Our members got actionable insight as to the effects of the base oil in their metalcutting fluids in terms of both performance and economics.

You may not know a lot about Organic Chemistry, but the photo above is worth a semester in class (as well as a thousand words!) to show us why now is the time to consider Synthetic base oils in our CNC and High Pressure coolant metalcutting operations.
