Characteristics of Oxygen
Oxygen is a gas without color, taste, or smell. While we breathe oxygen in the air, it is generally mixed with nitrogen. Oxygen displacement is a common result of many industrial processes, so it is important to measure oxygen levels and evacuate when the level drops below 19.5% volume, the OSHA-mandated level.

Frequently Asked Questions
What is an oxygen (O2) gas detector?
An oxygen (O2) gas detector is a device that is used to measure the concentration of oxygen (O2) in the air. The O2 detector uses electrochemical based sensors.
The use of an oxygen gas detector, particularly in environments with risk of low or high O2 levels like confined spaces, is essential for maintaining a safe work environment and preventing the risk of injury or death due to oxygen deficiency or enrichment.
At what level should an O2 detector alarm?
Accurate measurement of oxygen levels is crucial in confined spaces as low oxygen concentration is the leading cause of death. Workers must check and continuously monitor the oxygen level before entering such areas. If the oxygen concentration exceeds 23.5%, it becomes too oxygen-rich and may ignite combustible gases.
On the other hand, low oxygen levels below 19.5% of the atmosphere cause nausea, vomiting, and loss of consciousness, impairing judgment and coordination. In case of low oxygen levels, it's essential to identify the gas responsible for the displacement and the reason behind it.
What is O2 deficiency?
When the air we breathe lacks the necessary amount of oxygen to fuel our respiratory systems, it results in oxygen deficiency. The normal concentration of oxygen in the air is around 20.9% by volume, but when it drops below 19.5%, it causes symptoms like dizziness, confusion, rapid heartbeat, and impaired judgment. In severe cases, it can even lead to loss of consciousness, seizures, and death.
Oxygen deficiency can occur in confined spaces like tanks, silos, and tunnels, or in areas with poor ventilation and high-altitude environments where the air pressure and oxygen pressure are low. It's crucial to use appropriate oxygen detection equipment like oxygen gas detectors and follow safety procedures to minimize the risk of oxygen deficiency in the workplace.
