Wireless Gas Detectors for Confined Space Entries

Wireless gas detectors can help you perform safer confined space entries. The year 2018 marks the 25th anniversary of the implementation of permit required confined space entry regulations in the United States. Since then, the thousands of entries that take place across the country every day have become, shall we say, standard. We consult the written confined space program, assess the space for potential hazards, and... Read More

Have Stakeholders Kept Pace with Lowered TLVs and RELs?

Have Stakeholders Kept Pace with Lowered TLVs and RELs? 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

Advice for Using Gas Detectors in Cold Weather

Advice for Using Gas Detectors in Cold Weather 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

Infrared LEL Gas Sensors – Risk or Reward?

Infrared LEL Gas Sensors – Risk or Reward? 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

Limiting False Man-Down Alarms

Limiting False Man-Down Alarms 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
