Machine safety discussions have risen to new heights with the advent of improved technology and the availability of Internet communication. Beware: pay attention to the details. An EU (European Union) discussion may not fully apply here in the U.S.
ANSI Z10-2005 is a machine safety concern and an opportunity, as recently discussed. I barely finished that blog post when I was informed about a brand new ISO Project Committee (PC) 283 tasked to take Z10 to the international stage. The new ISO 45001 is planned for approval in late 2016, but what would happen to the ANSI Z10-2012 safety standard?
Cloud computing has been discussed by all the big guys (Microsoft, Apple, Cisco Systems, IBM, Google, Facebook, HP, Sony, etc.) for several years. Some suppliers have already developed hardware products that only store data in “the cloud.” And, machine safety experts have begun assessing how, or even if, “the cloud” can play any role in providing machine...
Category 3 and 4 architectures typically call for a control reliable (that is, redundant) circuit design no matter what safe logic solver under consideration: safety relay, safety PLC, safe drive, and so forth. So why would there be any confusion?
ANSI Occupational Health and Safety Management Systems standard ANSI Z10-2005 was updated, and the update approved on Sept. 5, 2012. This remarkable accomplishment created a national consensus standard for all types of organizations and companies regardless of size. A standard is not a guideline, and it carries compliance requirements. OSHA says ignorance...
Know the differences, when considering machine safety, between wireless and cableless. As an analogy, is your hand held smart phone, with all its Internet, social media, photograph and movie capabilities, wireless or cableless?
Can’t original equipment manufacturers (OEMs) have one design for global customers? For at least 15 years we’ve heard about “global harmonization” of machine safety standards. Perhaps OEMs can finally enjoy the economies of scale of one design for global customers?
Safety devices and e-stop machine safety requirements consistently raise questions and merit review. The universal (and global) emergency stop device is not so universally understood. An e-stop is NOT a safeguarding device and certainly an e-stop is NOT a reset button. Review these e-stop device requirements according to machine safety standards.
Know the 5 steps of the functional safety lifecycle. To perform functional safety and comply with safety standards like ISO 13849-1 and ISO 13849-2, design engineers need to know how to perform verification and validation measures; they are not the same step.
The standards march: where are they headed? Which will litigation reference? For compliance? As international standards (IEC and ISO) are increasing worldwide adoption they are cited in U.S. domestic machine safety standards from ANSI, NFPA, SEMI, ASTM, ASME, NEMA, etc. Are these standards adopting or referencing IEC or ISO requirements for compliance?
