Updates on the Texas fertilizer plant explosion and the Bangladesh factory building collapse, a preview of AIHce 2013 and an OSHA change in who may accompany its inspectors on “walkarounds” were all featured news on ISHN.com this week:

Nearly a month after the fertilizer plant explosion in West, Texas that killed 14 people and injured another 200, investigators are still unable to determine the cause of the tragedy.

The U.S. Chemical Safety Board (CSB) has established a Facebook page devoted to the April 17 West, Texas fertilizer plant explosion – and although a large photo of the memorial for the victims is prominent on the page, the ongoing FB conversation is mostly forward-looking.

Overcoming resistance to near-miss reporting: Easily ignored incidents can be key to improving safety performance. Even though a near-miss incident on a job site may cause no injuries or property or equipment damage, it can give a company a heads’ up about a need for early intervention, thereby enabling it to improve its safety performance.

While investigators in West, Texas, sift through the rubble of a fertilizer plant that exploded last week, killing 15 people, safety advocates are calling for stricter government oversight of potentially hazardous sites like that one. The operator of the plant, West Fertilizer Co., did file an emergency response plan update in 2011 with the EPA listing anhydrous ammonia on site, but did not indicate there was a risk of fire or explosion at the plant.
