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

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 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).
