OSHA Standard 29 CFR 1926 Subpart AA: Construction vs. Maintenance Work

The addition to OSHA Standard 29 CFR 1926 was designed to protect employees engaged in construction activities at work sites with one or more confined spaces.

A confined space is not designed for human occupancy. It has limited means of entering or exiting and can have a potentially hazardous atmosphere. Confined spaces may be poorly ventilated and, as a result, lack adequate oxygen or contain dangerous levels of toxic gases.

Before standard 29 CFR 1926, OSHA’s confined space regulations only applied to general industry. A gap grew obvious when the department of labor statistics reported most confined space fatalities were occurring during construction activities.

The new standard is very similar to the previous one, but applies directly to work in construction. It requires a permit to enter, pre-entry testing and continuous monitoring while inside the confined space.

While this new standard closes the gap in construction work, it leaves out one important component: maintenance.

TSI introduces environmental DustTrak for long-term monitoring

I know, I know. I haven’t posted anything in a while. I’d like to think of it as a summer vacation, but it reallyenvdt_closed wasn’t. But enough about me…

Over the summer, TSI introduced its new DustTrak which has been specifically redesigned for long-term outdoor environmental monitoring. While throwing the desktop version into a Pelican case or the other environmental enclosure works fine for short-term projects, the newer version is more rugged and designed specifically for long-term outdoor use.

Construction Workers Should Have More Protection From Silica Dust

roadconstructionIf you haven’t heard that silica dust can cause silicosis and can also lead to lung cancer, you’ve had your head in the sand for too long.

Sand. Silica dust. Get it? Ok, that was lame…

Anyway, it shouldn’t come as a surprise that this continues to be an area of concern. In the most recent issue of CA: A Cancer Journal for Clinicians, a new report finds that more should be done to reduce workers from exposure to silica dust. Researchers call for stronger regulations, increased awareness and prevention, and greater attention to early detection of silicosis and lung cancer using low-dose CT scanning.

The article on the NIH website states:

Noises off (a study in hearing protection)

Forgive the theater reference. I was reading a study from the University of Washington about noise exposure and found something interesting.  It stated that sheet metal workers were wearing hearing protection around 90% of the time when noise levels were above 85 dBA (OSHA’s standard for maximum exposure) when maintaining and fabrication metal products.

So they wear hearing protection when they are working? That makes sense, right? Don’t get me wrong: 90% compliance is great. But what I found interesting was how much that number dropped when workers were doing everything else.
