What are the effects of oxygen depletion?
Effects of exposure to low oxygen concentrations can include giddiness, mental confusion, loss of judgment, loss of coordination, weakness, nausea, fainting, loss of consciousness and death. The immediate effects of low oxygen environments are due to our body’s oxy- gen transport system.
How does an ODS work?
The ODS is an oxygen detection safety pilot system. It is designed to shut off the gas supply to the heater if the oxygen content in the room drops to 18% from a normal 21%+. In this event the pilot flame actually lifts off the thermocouple cooling it down and causing the gas valve to close and the heater to shut off.
What causes oxygen depletion?
Common causes of oxygen depletion include cloudy weath- er, sudden death of algae or plants in the pond, and wind mixing the pond water. Just two to three days of overcast weather can cause oxygen production to diminish. When the oxygen demand remains the same or increases, oxygen levels begin to decrease.
How can oxygen depletion be prevented?
Combatting oxygen depletion Treatments for oxygen depletion include mechanical aeration and the addition of hydrogen peroxide to the water. Oxygen water testing kits and quality meters are available, enabling continual monitoring and fast action as soon as a problem is detected.
Where is the oxygen depletion sensor located?
Where are oxygen depletion sensors used? Oxygen depletion sensors (ODS) are commonly found on vent-free heaters and fireplaces. The sensor is designed to shut off the fuel if the oxygen level in the room drops from 21% (normal air) to 18.5% oxygen by volume or below.
How does a vent-free heater work?
An unvented heating appliance, also called a vent-free appliance, has no chimney vent and is located in the space being heated. Combustion products are discharged into the heated space rather than exhausted to the outdoors through a chimney. Typical fuels are natural gas and LPG (propane).
How do you clean a gas fireplace with compressed air?
If there’s soot stuck in the holes of the burner, use a can of compressed air to dislodge the debris, followed by the vacuum to remove it completely. Wipe the burners with a damp cloth, and use a soft-bristle brush to remove any stubborn residue.
What are oxygen alarms and oxygen depletion alarms?
Safety Gas Detection manufactures oxygen depletion systems and enrichment gas detection systems which measure oxygen levels and provide oxygen depletion alarms and oxygen enrichment alarms. These systems can be supplied to measure other gases simultaneously.
Why is it important to know about oxygen depletion?
Even in situations in which Oxygen depletion does not reach life-threatening levels, the effect of Oxygen starvation on the health of working personnel is still a major health and safety concern. OX-AN® Oxygen Depletion Monitor Systems can detect Oxygen deficiency and warn occupants immediately of any danger.
Why do we need an O2 depletion monitor?
Oxygen (O2) depletion monitors are devices capable of measuring the ambient concentration of atmospheric oxygen and signalling when Ievels have fallen. This can enable action to be taken before an evacuation is required and levels become dangerous. In addition to oxygen depletion, problems arise when oxygen levels are too high.
How does the o2safeguard oxygen depletion system work?
The system is normally set to give a first stage warning alarm at 19.0% oxygen, and then a second stage full alarm at 17.0%. This enables action to be taken before an evacuation is required and evacuation before danger. The oxygen depletion system has a user interface, which for the O2SafeGuard is a full colour touch screen.
