What are VOCs?

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.

Monitoring and Analysis of Landfill Gases

As recycling becomes more common, use of landfill is reducing, but it is still an important means of waste disposal. For example, 2012-13 figures from Defra (department of the environment, food and rural affairs) for England show that 8.51 million tonnes, or 33.9%, of waste collected by local authorities went to landfill.

How dangerous is CO2 in the home? Chris looks into the importance of looking after your appliances

Last week we looked at Carbon Dioxide from an industry point of view, so this week I thought I’d highlight the dangers of this gas from a domestic side.

What is Carbon dioxide?

Carbon dioxide (CO2) is a gas that the human body produces naturally. Everyone is exposed, to some degree, to this gas every day. It occurs naturally in the Earth’s atmosphere as part of animal metabolism, plant photosynthesis, decomposition, and combustion. The gas is colourless, odourless, tasteless, non-combustible, is soluble in water and makes up slightly less than 0.5% of our atmosphere. CO2 is classed as a ‘greenhouse gas’ and increasing CO2 is debated to be one of the main causes of global warming.

Don’t be Complacent about Carbon Dioxide – how to stay safe

Carbon dioxide is a component of normal air, at around 0.037%. However, it can be produced by the burning of fossil fuels and other chemical reactions, and is a common component in the manufacture of many consumer products, notably beer and other fizzy drinks. Working in these environments risks exposure to levels elevated over the norm. At high levels, CO2 is a suffocation risk, and it can pose a significant toxic threat as well.
