Accuracy

Accuracy   When it comes to gas monitoring, accuracy is open to each manufacturer’s interpretation. Officially, accuracy is a statement expressed as a percentage of the closeness of the reading on the gas monitor to the actual concentration; many manufacturers use this as an umbrella term representative of much more, including resolution and sensitivity. To…

Calibration Gas Shelf Life

Calibration Gas Shelf Life Why is calibration gas important? When using your instruments for gas detection, monitors should be properly calibrated or your readings may be inaccurate. To properly calibrate your device, the user will need to use a specific concentration of the gas trying to be detected. This is known as a “calibration gas”,…

How to Reduce Gas Leaks in Industrial Environments

How to Reduce Gas Leaks in Industrial Environments Whether in petrochemical facilities, chemical plants, or refineries, workplaces that utilise or produce various toxic gases during normal operations and processes must meet industry safety regulations and requirements in the event of gas leaks. In addition to following regulations, personnel can take further preventative measures and precautions…

Understanding H2S in the Petroleum Industry

Protection against overexposure to H2S, a highly toxic and explosive gas, starts with understanding the chemical and the inherent risks it carries. Specifically to the petroleum industry, although, it’s not the only industry susceptible to the danger. The colourless gas H2S (known as a sour gas) is naturally produced by the decomposition of organic materials,…

Mine Ventilation

When air enters any mine or other subsurface structure, it has a volume composition of approximately 78 percent nitrogen, 21 percent oxygen and 1 percent other gases on a moisture free basis. However, as the air progresses through the network of underground openings, that composition changes.   There are two primary reasons for mine ventilation.…

The Effects of Methane

Methane is a component of the earth’s atmosphere and is present at low concentrations. We inhale methane along with other atmospheric gases such as nitrogen and oxygen when we breathe. At room temperature and pressure, methane is an odourless and colourless flammable gas and is composed of carbon and hydrogen with the chemical formula of…

What is Hydrogen Fluoride?

“What is Hydrogen Fluoride? Hydrogen fluoride, also known as hydrofluoric acid or HF, is a colourless, corrosive gas made up of a hydrogen atom and a fluorine atom. It is produced by reacting a naturally occurring mineral, fluorspar, with sulphuric acid.   Where Is It Found? Hydrogen fluoride is a raw material that is commonly…
