Japan's disaster has raised many questions regarding safety of the public. It has served as a wakeup call to the agencies tasked with protecting the public. Not least of these questions, but certainly the most far-reaching is the question of the safety of nuclear power and radiation contamination of air and water. Way back when nuclear power was first established, in the 1960s public opinion was ...

When storing or using Liquid Nitrogen, Helium, CO2, or Argon cylinders in a confined space, what are the potential risks? Gas leaks are the most common, requiring the need for an oxygen deficiency monitor for protecting employees in the workplace.  With inert cryogenic gases, loose or broken fittings can leak gas into a room displacing oxygen, causing impaired judgment or loss of life to ...

Continuous Monitoring vs. Badges Badges are designed to provide the Time Weighted Average (TWA) data for the total exposure period. They contain an absorption medium that reacts with or absorbs and holds the target chemical from the air to be analyzed later, which indicates the exposure after the fact. Badges, sample tubes, and wet chemical methods were the predominant technologies for monitoring ...

“Before the Cirrus System was installed we could never investigate noise complaints properly because the data from the time of the complaint was not available in retrospect. We needed noise monitoring instruments that would store data continuously, with software to interrogate the monitors and download data, to give us a complete history of the noise levels at our boundaries. We have ...

Abstract An important safety aspect of the workplace environment concerns the severity of its air pollution with nanoparticles (NP; \100 nm) and ultrafine particles (UFP; \300 nm). Depending on their size and chemical nature, exposure to these particles through inhalation can be hazardous because of their intrinsic ability to deposit in the deep lung regions and the possibility to subsequently ...

Abstract A new generation of continuous particulate matter concentration monitoring instruments is presented, covering a measuring range of 0 to 1000 mg/m3. The laser-based scattered light instrument gives an improved stability as well as excellent resolution in the low range. This enables high concentration measurement as well as especially low emission monitoring down to 0.01 mg/m3 with a ...

In 1993, 29 CFR 1910.146 went into effect as the first federal legislation governing entry into permit-required confined spaces in general industry. Because some industries, such as the construction industry, were covered by specific Occupational Safety and Health Administration (OSHA) safety regulations, they were exempt from the confined space entry requirements of the general industry rule. ...
