Carbon Dioxide – Friend and Foe?

Carbon dioxide (CO2) gas is commonly used in the manufacture of popular beverages. The leak at the Greene King brewery in Bury St Edmunds (UK) last week, is a reminder of the importance of effective gas detection. It resulted in twenty workers having to be rescued by emergency services and local residents being evacuated. So what is carbon dioxide, why is it dangerous and why do we have to monitor it carefully?

Accurate monitoring of exposure to toxic gases using TWA

Unique to T4, the TWA Resume function ensures toxic gas exposure is calculated accurately over an entire shift, even if T4 is switched off for a break or during travel to another site.

When most portable detectors are turned off, the algorithm that assesses TWA exposure assumes that it’s the end of the shift. When turned on again, these detectors act as if it is a new work shift, ignoring all previous measurements. The TWA Resume function however, provides the option to include previous measurements from within the correct time frame.

Do you give a STEL about your TWA?

By answering this short survey on use of alarms on your portable gas detection device, it will help us improve our training materials, as well as our communication generally. We would very much appreciate your input, It takes less than two minutes, and your responses are completely anonymous.

If you would like further information on exposure limits, please take a look at our blog entry from 21st August 2014.

What is a time-weighted average? Chris explains the importance of them when toxic substances are involved

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.
