Join this ongoing discussion of machine guarding topics, including solutions assessments, regulatory compliance, gap analysis, operating efficiencies and cost savings, as well as all relevant safety standards, such as those from NFPA, ANSI, RIA, IEC, ISO and OSHA.
Machine guarding and the hierarchy of measures for hazard mitigation
October 25, 2011
Do you know the five levels of hazard mitigation? Machine guarding isn’t completed task that’s checked off a list. Eliminate, isolate, add engineering, implement controls, and use PPE, then repeat. » more

ISO 13849-1 Machine Guarding Adoption, Part 4 - safety standard merger
September 24, 2011
Adopting EN ISO 13849-1 by Dec. 31, 2011 has been taking a lot of attention this year particularly for manufacturers of machinery and global end users. Guess what? The IEC (International Electrotechnical Commission) world and the ISO (International Standardization Organization) world are voting to merge EN ISO 13849-1 and IEC 62061. Yikes – when will... » more

ISO 13849-1 Machine Guarding adoption, Part 3
September 01, 2011
What is your plan to comply with the ISO 13849-1 Machine Guarding standard? By now you’ve attended seminars, read white papers and magazine articles, heard from colleagues, or even read some of these blogs on this subject. So what? We don’t legislate compliance in the US. Instead, we have consensus standards. » more

ISO 13849-1 Machine Guarding adoption, part 2
August 24, 2011
The scope statement in the machine guarding standard reads, “This part of ISO 13849 provides safety requirements and guidance on the principles for the design and integration of safety-related parts of control systems (SRP/CS), including the design of software. For these parts of SRP/CS, it specifies characteristics that include the performance level... » more

ISO 13849-1 Machine Guarding adoption, part 1
August 19, 2011
Let’s assume that adopting ISO 13849-1 for Machine Guarding is unavoidable. That said, the “professorial” view is to train/educate everyone in industry about the requirements for compliance and possible business advantages. Then, there’s the “practical” view... » more

I don’t have to upgrade my machine safety to the latest technology
August 10, 2011
I’ll bet nearly everyone reading this blog has heard someone say, “I don’t have to upgrade my machine safety to the latest technology.” Right? And, the next comment might be something like, “My shop is safe because we haven’t had an accident for umpteen years.” Are these folks wrong? Here are 5 questions to ask about machine safety. » more

Machine Safety Pays
August 03, 2011
Does management in your organization really understand that safety pays back directly to the bottom line? Do they understand that the cost of accidents goes directly to the bottom line and potentially requires several million dollars of incremental sales as an offset? One accident can result in financial chaos at least 10 ways. How? » more

Not Again – E-Stops Do Not Equal Machine Safety
July 19, 2011
How many times does this issue come up? An e-stop device is not a safety device! Therefore, it’s not a part of the safety related parts of a control system (SRP/CS). Then, why is an e-stop device so often confused as being part of the safety design for a machine? » more

Machine safety and degrading component reliability
July 14, 2011
Is your machine downtime sometimes a surprise? Did a component in a safety circuit fail because it simply wore out and nobody knew it was about to fail? Well, maybe help has just arrived. Has anyone heard about EN ISO 13849-1; 2008? See "4 ways to reduce surprise downtime." » more

We’re safe; we’ve had no machine safety accidents for a long time
July 05, 2011
All too often I hear or read about a companies’ great safety record only to read on about a major incident or accident and the devastating human and/or business impacts that occur. One central place to stay current regarding safety in general as well as specific incidents is OSHA’s twice monthly email report titled OSHA Quick Takes. » more
