Oxygen: Crucial for life!

Concentrations above the 19-23% safe zone can result in an increased fire risk. Concentrations

below 19% can risk nausea, loss of consciousness and below 16% death.

Flammables: Anything which in the correct concentration can be ignited, e.g. Methane.

ATEX, IECEx & CSA certified so it can be used in areas where flammable gases are present.

CO: Odourless, colourless and with a similar density to air, carbon monoxide is the ‘silent killer’

Present in any process involving incomplete combustion of carbon fuel, naturally present in coal mines, and also

used in some chemical and steel production processes.

High levels can lead to breathlessness, chest pain, seizures, loss of consciousness, and eventually death.

The 4 Main Gases

H2S: Hydrogen sulphide is known for its ‘bad egg’ odour. High levels can lead to

collapse, respiratory paralysis, convulsions, loss of consciousness.

Produced during decay of organic materials, during oil extraction and pretty much anywhere

where sewage is being processed.


Other Gases the Gasman Detects:

SO2: This toxic gas is responsible for the ‘burnt matches’ smell and is a by-product of

copper extraction and volcanic activity. Used in the bleaching process in paper making

and as a preservative in breadmaking. By-product of cement manufacture.

Sulphur dioxide can irritate the respiratory system, especially during heavy physical activity which

is why it is dangerous.

NH3: Ammonia is a combination of nitrogen and hydrogen which form a colourless,

pungent gas. NH3 serves as the starting material to produce many commercially

important nitrogen compounds and can be used as a refrigerant or as a fuel.

Exposure to high concentrations of the gas can cause burning of the nose,

throat and respiratory tract and in extreme cases, can be fatal.

CO2: Carbon Dioxide is a naturally occurring colourless, tasteless, odourless gas.

It is heavier than air which causes issues in cellars where CO2 is commonly stored since it is difficult to ventilate.

Build ups of CO2 can displace oxygen which makes it an asphyxiant as well as toxic depending on its

concentration.



HCN: Hydrogen cyanide is very toxic, even at very low dosages (4.5ppm / 0.00045%

volume) and has a ‘bitter almonds’ taste. HCN can be found in metal mining

processes, plastic production, PCB manufacture, ship fumigation and as a by-

product of fires involving synthetic fibres.

It prevents cells from respiring so symptoms range form dizziness to respiratory failure and

death depending on exposure time and concentration.

O3: Ozone forms naturally in the stratosphere, during thunderstorms and can be

manmade, ether way it has a blue colour and sharp smell.

If O3 is inhaled it can damage the lungs, resulting in chest pain, coughing, shortness of

breath and throat irritation.



CI2: Chlorine is commonly known as a method of sterilising swimming pools and drinking water.

However, most chlorine is used in the chemical industry with typical applications including

bleaching, paper mills (bleaching pulp), disinfection, as well as within the plastics and chemical

Industry.

If chlorine gas is released into the air, people may be exposed through their skin, eyes or through

inhalation. Chlorine is toxic and if inhaled can prove fatal.

NOₓ: This is the term given to NO and NO₂ nitric-oxide and nitrogen-dioxide. Both can be

produced as a by-product of combustion processes within power stations or boilers, as well as

combustion cars and are common urban pollutants. NO2 is also a key constituent of nitrogen-

based fertilisers, while NO is also industrially produced for medical and food applications.

NO can act as an asphyxiant as it replaces oxygen in the blood and can result in loss of

consciousness. NO₂ can inflame airways and with prolonged exposure, can permanently damage

lungs.


H₂: Hydrogen gas is the building block of our universe since it the most common and simple

of all elements. It can explode with air, oxygen, halogens and strong oxidants, causing

obvious dangers. Hydrogen is widely expected to replace traditional carbon-based fuels. Gasman can detect H₂ in %LEL and 2000 parts per million (ppm) ranges, depending on

application and sensor specified.

HF: Hydrogen Fluoride is a colourless gas with a strong odour. When dissolved in water it

creates Hydrofluoric acid which is used in metal extraction, refining, glass finishing and in the

production of refrigerants, herbicides and florescent lightbulbs.

Both fluids are corrosive and can cause significant harm, irritation and burns when in contact

with skin or breathed in. Hydrogen fluoride is deadly.

F2: Fluorine gas is pale-yellow in colour and is used in the chemical industry, within nuclear

plants and has uses with military applications.

It causes irritation to any human tissue it contacts by reacting with it. It also reacts with all

other elements apart from argon, neon and helium.



PH₃: Phosphine is colourless and highly toxic, with concentrations at 50ppm proving fatal,

and far less concentrations causing fatality over an extended period.

It is used in the semiconductor/ microelectronics industry and as a fumigant against pests.

COCl₂: Phosgene is a highly toxic gas with the odour of freshly cut hay, commonly used

industrially in the production of certain plastics, dyes and acidic chlorides.

Known for its historic use as a chemical weapon it quickly irritates eyes, throat and lungs.

ClO₂: Chlorine Dioxide is a yellowish-green corrosive agent that is a common bleaching

agent used in multiple industries, and becoming more common in clean water purification.

It causes damage to any human tissue it touches as well as being flammable at higher

concentrations.

ETO: Ethylene oxide is colourless, with a small exposure limit over 8 hours of just 1 ppm.

ETO is used as a sterilant and fumigant and is also used in in the manufacture of ethylene

glycol, surfactants and other chemicals.

It can cause irritation to eyes, skin and respiratory tissues as well as cancers and other long

term health defects.

Application Showcase

Oil and GasThe oil and gas industry is a dangerous workplace, and

management of hazards a key focus. For the operator,

maintaining a high level of plant safety is a critical concern. The

most obvious and significant threat is the leakage and

combustion of explosive gas. With hazardous gases ever

present during production and processing operations, operators

are constantly faced with the risk of flammable and toxic gas

release and exposure. Gasman is ideal for detecting flammable

gases because it is easily configurable and durable.

Beverage & HOREGAThe Gasman can be specified with an IR CO2 sensor

configuration which is great for cellars and storerooms in the

beverage and HOREGA sectors because of its quick alarm

time.

It protects against CO2 poisoning, the most prevalent hazard

in those environments.
