OX-AN's CO2, Temperature & Humidity Monitor Will Help You Provide A Safe & Comfortable Environment

The UK Health and Safety Executive (HSE) states that employers must stick to health and safety at work law by keeping the temperature at a comfortable level, sometimes known as thermal comfort and providing clean and fresh air. https://www.hse.gov.uk/news/workplace-temperature.htm

The Threat of Dangerous CO2 Levels To Our Health & Wellbeing

5000 PPM & above Coma or death
4000 - 5000 PPM Severe hypoxia or permanent brain damage
3000 - 4000 PPM Accelerated heartbeat, mild nausea
2000 - 3000 PPM Feeling dizzy and unable to concentrate
1000 - 2000 PPM Feeling cloudy or drowsy
450 - 1000 PPM Feel comfortable and breathe easily
350 - 450 PPM The air is fresh and refreshing

OX-AN Detection Functions

Managing The Internal Environment


CO2 is naturally present in the air we breathe at a concentration of about 0.037% and is not harmful to health at low concentrations. At room temperature and atmospheric pressure CO2 is a colourless and odourless gas and, because of this, people are unable to see it or smell it at elevated concentrations. CO2 is not flammable and will not support combustion. As the concentration CO2 in air rises it can cause headaches, dizziness, confusion and loss of consciousness. https://www.hse.gov.uk/carboncapture/carbondioxide.htm


In offices or similar environments, the temperature in workplaces must be reasonable. The HSE state that the temperature in a workplace should be established for the 'thermal comfort' of your employees. Thermal comfort describes a person's state of mind in terms of whether they feel too hot or too cold. How the effects of temperature are managed in your workplace depends on whether it is indoors or outdoors and the normal operating temperature of that environment. With regard to indoor workplaces, a reasonable working temperature in workrooms – usually at least 16°C, or 13°C for strenuous work (unless other laws require lower temperatures) https://www.hse.gov.uk/news/workplace-temperature.htm


The UK Health & Safety Executive state that “Very low relative humidity, less than 20%, may sometimes cause skin or eye problems in some individuals. It is unlikely that low relative humidity itself is a cause of SBS, but indirect effects may have a bearing on factors such as static electricity build-up, off gassing, and the presence of airborne dusts and fibres. High relative humidity, in excess of 70%, is uncomfortable, and health may be threatened through the development of surface condensation and mould growth. Levels of relative humidity in the range of 40 to 70% are recommended for the workplace environment.”
