What is the minimum safe level of oxygen?

The minimum oxygen concentration in the air required for human breathing is 19.5 percent. The human body takes the oxygen breathed in from the lungs and transports it to the other parts of the body via the body’s red blood cells.

What are the minimum and maximum safe oxygen levels?

OSHA dictates that the minimum “safe level” of oxygen in a confined space is 19.5\%, while the maximum “safe level” of oxygen in a confined space is 23.5\%.

What is the safe range for oxygen in a work area?

19.5 percent
OSHA Oxygen Level Standards To meet the minimum standard set by OSHA, your employer’s workplace must have an oxygen concentration of at least 19.5 percent. This minimum is slightly lower than the normal concentration of oxygen of 20.8 to 21 percent in our atmosphere.

What is normal oxygen level in air?

Human beings must breathe oxygen . . . to survive, and begin to suffer adverse health effects when the oxygen level of their breathing air drops below [19.5 percent oxygen].

What percentage of oxygen is safe for humans to breathe?

Safe Oxygen Levels For humans and many animals to sustain normal functions, the percentage of oxygen required to sustain life falls within a small range. The Occupational Safety and Health Administration, OSHA, determined the optimal range of oxygen in the air for humans runs between 19.5 and 23.5 percent.

What should your oxygen level be in the UK?

The aim here in the UK is to keep saturation levels at around 92\% as a low. But be aware. Different countries have vastly different ideas on what levels is needed and what is not. If you notice your blood oxygen level is 88\% or below get in contact with your medic as soon as possible and ask if you need oxygen.

What happens if your oxygen level is 88?

Some get very breathless even though blood oxygen levels are good. But if your oxygen level is 88 or below you will without doubt be prescribed oxygen as to stay at such low levels almost certainly will cause harm. The aim here in the UK is to keep saturation levels at around 92\% as a low. But be aware.

What are the dangers of oxygen?

Handle with extreme caution. * Contact with liquid Oxygen can cause severe skin and eye irritation and burns as well as frostbite. * Breathing pure Oxygen at high pressures can cause nausea, dizziness, muscle twitching, vision loss, convulsions (fits), and loss of consciousness.
