The purpose of risk assessment

This entry is part 3 of 9 in the series Risk Assess­ment

I’m often asked what seems like a pretty simple ques­tion: “Why do we need to do a risk assess­ment?” There are a lot of good reas­ons to do risk assess­ments, but ulti­mately, the pur­pose of risk assess­ment is best summed up in this quo­ta­tion: “Risk assess­ments, except in the simplest of cir­cum­stances, are not designed for mak­ing judge­ments,…

Manufacturing Automation Roundtable

I had the great pleas­ure today of par­ti­cip­at­ing in a round table dis­cus­sion that was held by Man­u­fac­tur­ing Auto­ma­tion magazine at their headquar­ters in Aurora, Ontario. Around the table were: Eliza­beth Rankin – CSA, Wayne De L’Orme – Ontario Min­istry of Labour, Dave Lawson – Advanced Motion & Con­trols, Jeff Math­yssen – Elec­tro-Mag, Rick Sauer – Festo,…

The “Inconceivable” Consequences of Failure

A col­league of mine poin­ted me to this inter­est­ing art­icle by Don­ald Chris­ti­ansen that was pub­lished in the August edi­tion of IEEE USA’s Today’s Engin­eer magazine.
As engin­eers design­ing equip­ment, we nor­mally con­duct some form of risk assess­ment. Although many com­pan­ies are still using inform­al and undoc­u­mented meth­ods, meth­od­ic­al, doc­u­mented risk assess­ments are becom­ing the norm in industry.

Since under­stand­ing the risk related to our designs is fun­da­ment­al

Hazard Identification – Engineered Nanoparticles

Under­stand­ing the haz­ards presen­ted by pro­cesses is crit­ic­al to pro­tect­ing work­ers. Nan­o­particles are enter­ing the work­place in new products and pro­cesses, but the haz­ards are not well under­stood. Read this art­icle to learn more.

Safety is Good Business

In this excel­lent art­icle from Rock­well Auto­ma­tion’s The Journ­al, Mike Miller and Wayne Sol­berg explain how EN ISO 13849 – 1 and EN IEC 62061 mesh for machine build­ers.

Well worth the read in my opin­ion!

Interlocked gate testing

Did you know that inter­locked gates require stop­ping per­form­ance test­ing?

Machinery needs to be able to stop in the time it takes a per­son to open the guard and reach the haz­ard. If the dis­tance from the guard open­ing to the haz­ard is short enough that a per­son can reach the danger point before the haz­ard can be con­trolled, the guard is use­less. The res­ult­ing situ­ation may be worse
