Over the last several years, organizations such as the American Conference of Governmental Industrial Hygienists (ACGIH) have lowered their Recommended Exposure Limits (RELs) on a number of common hazardous gases. For example, the ACGIH dramatically lowered the Threshold Limit Values (TLVs) for both hydrogen sulfide and sulfur dioxide. In similar fashion, the ACGIH has named in its 2017 Notice of Intended Changes list other... Read More
With the month of October comes the beginning of cold weather season in the northern hemisphere and concerns about how well your portable gas detection equipment will function when winter puts its death grip on the thermometer. Some instruments are rated as low as -40 degrees; however, the low temperature rating for continuous operation of most portable gas monitors is -20 degrees Celsius. Even so, most instruments may be... Read More
What are the limitations of infrared LEL gas sensors? There has been a lot of recent discussion about the benefits of infrared LEL gas sensors for the oil and gas industry. There have even been claims that these sensors operate for years without calibration while extending instrument run times from hours to months without recharging batteries. The benefits of infrared technology over the industry standard catalytic bead... Read More
Gas detector manufacturers today are trying to provide end users with functionality that goes beyond gas detection. Slips, trips, and falls are some of the most frequent types of workplace accidents. Due to that fact, several instruments on the market now offer man-down alarms or panic alarm functionality. If a worker becomes disabled and is in need of help, he can trigger the panic alert on his monitor, which will activate... Read More
You see them and drive past them all the time. Every community has one. Chances are that a close neighbor, one of your best friends, or even a member of your family may work in one. When low pressure sets in, and the wind blows in the right direction, the stench is horrific. But the smell is only a hint to the abundant hazards that you might encounter when working at a wastewater treatment plant. The potential for slips,... Read More
