Health and Safety
The most important environmental monitoring looks out for conditions that deliver short and long term harm to human health. Personnel and fixed detection look out for dangers caused by flammable and toxic gasses and IAQ monitors look for longer term dangers caused by poor working conditions.
Gas DetectionWessex Power offer a range of portable/fixed gas detectors from the worlds leading suppliers of Oxygen, Toxic and Flammable gas detection systems. BW Technologies by Honeywell Analytics (Neotronics, Sieger) and ION Science.
Oxygen DepletionOxygen depletion monitoring systems are installed to guard personnel who need to enter rooms where either Nitrogen or Carbon Dioxide is used for Cryogenic storage.
These gases are usually used for incubators as well as storage Dewar’s used in the storage of various tissues and cells.
Oxygen should read 21% in normal atmospheres, a drop below 18% should issue a warning clearly visible to personnel accessing the storage area.
Personnel gas detectors set to alarm at 18% are effective if the levels are dropping from 21% to 18% however a fixed gas sensor mounted inside the storage area connected back to a transmitter with a clear display will offer greater protection, preventing personnel entering a room where there are depleted levels of oxygen.
• 14% - Reduces the ability to think , muscular co-ordination and accelerates pulse rate.
• 14-10% - Causes increased pain threshold and heightened emotions.
• 10-6% - Causes nausea and vomiting, and may cause permanent damage of the brain .
• 6% - Causes convulsive movements and breathing stops.
