A ‘Belt & Braces’ Approach to Personal Safety During Maintenance Shutdowns

by | Jul 30, 2020 | Latest News

Maintenance on plant and equipment is often carried out to prevent problems arising, ensure equipment is working effectively and to increase reliability. Usually, these programs are continuous over the year and present the cost benefits of better productivity and efficiency. For plant maintenance to go as planned, extra gas detection equipment may be needed to accelerate the maintenance program.

Plant shutdowns for planned major maintenance work are the most expensive and time-consuming of maintenance projects because of the loss of production and the expense of the turnaround itself. This level of high quality is usually maintained by a complete plant shutdown every 12 or 18 months.

During plant shutdowns, storage tanks, silos and warehouses may be cleaned or flushed out by maintenance teams. Employees may be required to carry out work in areas that have been inactive for several months; as a result, dormant gases will be disturbed, presenting a higher risk hazard. Therefore, plant managers to must guarantee worker safety upon entry to these areas. Confined space entry equipment must be available to protect maintenance teams against harmful hazardous process chemicals.

The BM25 Area Gas Monitor

BM25 area monitor from Oldham

A popular choice for around the clock protection during plant maintenance is the Oldham BM25 area gas monitor. Packing all the benefits of a fixed gas detector into a portable gas detector, the BM25 is a rugged transportable, area gas monitor that is often used alongside personal gas detectors to provide a tough ‘belts and braces’ safety approach.



Designed to work in hazardous areas for prolonged periods of time, the BM25 area gas monitor is equipped as standard with a high capacity battery pack, offering up to 170 hours uninterrupted battery run time. The BM25 area gas monitor is able to provide an early indication of toxic and combustible gas leaks using powerful audible (103 dB) and bright, flashing visual alarms to alert personnel, giving users peace of mind.




The GMI PS200 Personal Gas Detector

The PS200 is a suitable multi-gas detector usually worn on a belt or clipped to workwear. This multi-gas detector can provide detection of 1-4 gases with a continuous run time of up to 80 hours (when using the low power LEL sensor). Any PS200 with the 5-year O2 cell installed can have an optional man-down alarm sensor installed.

In addition to displaying all gas readings simultaneously, the PS200 retains the last five bump test and calibration data. Once the PS200 is placed in the dock it can be tested, calibrated, and charged. The user can also initiate a manual bump test anytime using the Auto Bump/Calibration (ABC) test station.


This provides the ability to ensure that instruments are properly tested before each use. If you’re unsure how to do this a1-cbiss can provide full product training to ensure that workers understand how their detectors work and what to do in the event of an alarm.





Here at a1-cbiss, our collaborative approach allows safety to remain the number one priority on site.

Using industry-wide best practices gained over the years we will work alongside you during the project, to ensure that everything operates in accordance with onsite health & safety rules, giving your employees the confidence to rely on their gas detectors.
