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.

Identifying haz­ards is the first step in the risk assess­ment pro­cess, but to do this effect­ively the haz­ards must be under­stood. Engineered nan­o­particles, like car­bon nan­otubes, are begin­ning to show up in a wide vari­ety of products. The prob­lem is that their haz­ards are not well under­stood.

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

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 than not hav­ing a guard because it’s pres­ence leads to a false sense of secur­ity in users.

Test the stop­ping time of guarded haz­ards and make sure that guards are far enough away from the danger zone to be effect­ive. For more on stop­ping per­form­ance require­ments, see CSA Z434, EN 999 (soon to be replaced by EN 13855:2010), and in the USA, 29 CFR 1910.217(h)(9)(v).
