Machinery Safety 101

New Directions in Plastics Machinery

Canada’s Par­ti­cip­a­tion in ISO TC 270 In Feb­ru­ary of 2016, Canada formed the SCC Mir­ror Com­mit­tee (SMC) to ISO TC 270, Rub­ber and Plastics Machinery. This inter­na­tion­al tech­nic­al com­mit­tee is cur­rently devel­op­ing ISO 20430, the first inter­na­tion­al plastic injec­tion mould­ing machine stand­ard. Until the pub­lic­a­tion of ISO 20430, two stand­ards have been fight­ing for dom­in­ance: EN 201, Plastics and…

Workplace Risk Assessment – CSA Z1002: Love it, Hate it, Tweak it

The CSA Z1002 TC Needs to Know: Love it, Hate it, Tweak it? We need to know: Do you Love CSA Z1002? Hate CSA Z1002? Does it need some tweak­ing? The First of Its Kind In 2012, CSA pub­lished the first OHS Risk Assess­ment Stand­ard of its kind: CSA Z1002, Occu­pa­tion­al health and safety — Haz­ard iden­ti­fic­a­tion and elim­in­a­tion and…

Public Review: CSA Z1006 Management of Work in Confined Spaces.

CSA Z1006 Man­age­ment of Work in Con­fined Spaces  is now avail­able for Pub­lic Review.  As new stand­ards are developed, and exist­ing stand­ards are revised, they are made avail­able for pub­lic review and com­ment. If you are inter­ested in Con­fined Space Entry, and would like an oppor­tun­ity to review the pro­posed changes to the stand­ard, read…

Why should you get involved in Standards Development?

It’s now been more than 30 years since I first learned about stand­ards, in the form of the Ontario Elec­tric­al Code. I was study­ing elec­tri­city and elec­tron­ics in high school, and Steve Struk, the Elec­tri­city Teach­er at Erindale Sec­ond­ary School in Mis­sissauga, intro­duced us to the rules. My first encounter with inter­na­tion­al stand­ards was 25 years ago, when I was tasked…

CSA Z432 Safeguarding of Machinery – 3rd Edition

If you build machinery for the Cana­dian mar­ket, or if you modi­fy equip­ment in Cana­dian work­places, you will be famil­i­ar with CSA Z432, Safe­guard­ing of Machinery. This stand­ard has been around since 1992, with the last major revi­sion pub­lished in 2004. CSA has recon­vened the Tech­nic­al Com­mit­tee respons­ible for this import­ant stand­ard to revise the…

Why YOU need a Product Safety Certification Strategy that Works!

How com­pli­ance efforts go wrong Cli­ents call me when they have prob­lems. They sent some product to a cer­ti­fic­a­tion body, some tests were done, and the product failed. Now what? Usu­ally, the deliv­ery date for the cer­ti­fied product is approach­ing quickly, and no time is avail­able to react. Deliv­ery is delayed, and the cus­tom­er is upset.…

The Third Level of the Hierarchy: Information for Use

This entry is part 3 of 5 in the series Hier­archy of Con­trols

I’ve writ­ten about the Hier­archy of Con­trols in past posts, but I’ve focused on the ‘engin­eer­ing’ side of the con­trol equa­tion: Phys­ic­al changes to machine design to elim­in­ate haz­ards, and mech­an­ic­al or elec­tric­al con­trol sys­tems that can reduce risk. The first two levels of the Hier­archy, Elimination/Substitution and Engin­eer­ing Con­trols, are typ­ic­ally more chal­len­ging to…

31-Dec-2011 – Are YOU ready?

This entry is part 8 of 8 in the series Cir­cuit Archi­tec­tures Explored

31-Decem­ber-2011 marks a key mile­stone for machine build­ers mar­ket­ing their products in the European Uni­on, the EEA and many of the Can­did­ate States. Func­tion­al Safety takes a pos­it­ive step for­ward with the man­dat­ory applic­a­tion of EN ISO 13849 – 1 and ‑2. As of 1‑Janu­ary-2012, the safety-related parts of the con­trol sys­tems on all machinery bear­ing a CE Mark will be…

Inconsistencies in ISO 13849 – 1:2006

This entry is part 7 of 8 in the series Cir­cuit Archi­tec­tures Explored

I’ve writ­ten quite a bit recently on the top­ic of cir­cuit archi­tec­tures under ISO 13849 – 1, and one of my read­ers noticed an incon­sist­ency between the text of the stand­ard and Fig­ure 5, the dia­gram that shows how the cat­egor­ies can span one or more Per­form­ance Levels. If you look at Cat­egory 2 in Fig­ure 5, you will notice…

Standards in Music

Work­ing in a field that is stand­ards heavy, I often get ques­tions from cli­ents and stu­dents about the ori­gin of stand­ards. Recently I heard a dis­cus­sion on CBC radio talk­ing about the ori­gins of music­al nota­tion, and I real­ized that this is prob­ably one of the earli­est examples of stand­ard­iz­a­tion. Here’s the story as I under­stand it. In the early days…
