Next in our series of short videos is our hydrogen sulphide detection factoid.
Where is H2S found?
Hydrogen sulphide is a significant danger to workers in many industries. It is a by-product of industrial processes, such as petroleum refining, mining, paper mills, and iron smelting. It is also a common product of the biodegradation of organic matter; pockets of H2S can collect in rotting vegetation, or sewage itself, and be released when disturbed.
The nature of gas hazards posed by some working environments can be complex and complete protection is not available from a single solution. This week, our guest blogger, Richard, takes a look at VOCs: how they pose a hazard and what we can do to protect against them.
Last week we looked at the toxic gas, Hydrogen sulphide, and briefly went through TWAs, so I thought this week I’d go into more detail about TWAs and the importance of them, especially when coming into contact with toxic gases.
As mentioned last week, toxic gases are considered to be those gases that can cause injury, illness or a reduced length or quality of life. Low concentration may not cause a problem or be noticed, but prolonged exposure may cause chronic illness or even premature death. The regulatory bodies are constantly working on acceptable exposure limits and these must be remembered when considering the purchase of a toxic gas detector.
