Gas Monitor Bump Testing vs Calibration
We are often asked to explain the difference between calibrations and bump testing. This is a controversial subject. OHS would have you do a full calibration before each use. In practice, our customers come up with their own intervals. If the gas monitor is used infrequently, say once a month, it should be calibrated every time to give you confidence that the unit is going to respond as it ...

Subsurface Gas Monitoring
So, what can be done to mitigate the potential drastic effects? Whether a landowner, developer or regulator the objective is identical; namely to ensure that any existing or proposed development remains or takes place safely. But because of the temporal or seasonal effects on ground gas migration, monitoring has to be undertaken over a potentially wide geographic area, lasting several ...

Automatic calibration saves big
Automatic gas sensor calibration technology was developed by Rel-Tek and proven over a decade of industrial applications involving large alternative fuel, transit bus garages. CNG, LNG, LPG and hydrogen fuels present the possibility of explosive gas buildup indoors, so sustaining the accuracy of the installed gas monitoring system is a never-ending responsibility for the owner. Rel-Tek's ...

Planning for a Gas Monitoring System
Do you need a gas monitoring system? Then you already know which gases you want to monitor, you probably have an idea of measurement ranges and accuracy requirements, and perhaps you have a budget for the system. But which other aspects have to be considered, and how do you actually design the system? Whether it is about air quality monitoring, continuous emissions monitoring or process control, ...

Lone workers in the hierarchy of safety controls - Case Study
A large oil and gas producer was in the market to outfit lone workers with new safety equipment at one of its operations in the western United States. Lone worker solutions have come a long way in taking full advantage of current technology. While lone worker solutions are important, they only make up a small portion of the PPE (personal protective equipment) market. “Industrial ...

Chlorine Safety and Prevention: How to Protect Yourself from Chlorine Leaks
While chlorine gas is widely used in swimming pools, water treatment facilities, cleaning products, pharmaceutical products, and in many other industries, the gas is highly toxic when handled improperly. Training your workers on how to safely use chlorine is one part of health and safety best practices; monitoring your workplace for chlorine leaks is another. Learn about the hidden dangers in ...

Radius BZ1 area monitor with LENS™ wireless provides ideal solution
Challenge Five area gas monitors, one at each level of a Coker unit, were set up at one of the world’s leading oil refineries. With use of repeaters, each unit was configured to report information back to a central laptop computer. The lengthy setup time and issues with latency and signals burdened by the Coker unit infrastructure made this configuration challenging. Transmission of ...

No Need for Redundant Systems
How many gas monitoring systems does it take to measure a gas concentration? Strangely enough, the answer is not always one. Gas concentration monitoring is not always an easy task. In the ideal world, a monitoring system needs no maintenance, it is infinitely fail-safe, and it operates impeccable irrespectively of the conditions of the gas. However, then reality hits the system with more or less ...

Effects of averaging time on predicted gas concentrations
The potential consequences of a particular gaseous emission usually relate to a specific averaging time. However, the averaging time associated with gas monitoring data in the region of a discharge may differ from the averaging time implicit in a model employed to predict the concentration resulting from that emission. Tables of factors exist for taking account of such differences and recent ...

New gas detection equipment and iNet exchange restore consistency - Case Study
Challenge Two neighboring off-shore rigs owned by one of the world’s largest oil companies set the stage for a much needed unified solution: Platform 1, over twenty years in operation, equipped with an aging gas detection fleet that required ongoing heavy maintenance and replacement of parts; and Platform 2, a much newer counterpart, interchangeably operated by some of the same ...

Offshore gas monitoring for health and safety
Summary The need to maximise availability and to implement the most challenging of drilling plans, while all the time meeting stringent health and safety requirements, places immense pressures on offshore facilities managers. The costs of downtime and any subsequent clean-up due to an incident are unthinkable, and the costs of ill health are growing. Legislation demands the implementation of a ...

The latest ground Gas monitoring innovations
The latest Ground Gas monitoring innovations The traditional methodology for ground gas monitoring has been ‘spot monitoring’ – taking event readings at various set times to predict the sub surface gas regime on both on Brownfield and Landfill sites. This methodology is in general current practice under both the EU Landfill Directive 1999/31/EC which is supported by ...

Municipal solid waste management in Jodhpur city, Rajasthan (India) - current status
Jodhpur city is the second largest city of Rajasthan State, having population of about 1,077,717 and an area of 232 sq km. The city generates around 380 t/d of municipal solid waste (MSW). With the increase in population, urbanisation and industrialisation, the problems of handling MSW have significantly increased in the past few years. There is no arrangement for segregation of waste at source. ...
