What Carbon Monoxide level requires the use of SCBA?

Using Self-Contained Breathing Apparatus (SCBA) in environments with elevated levels of carbon monoxide is essential for ensuring the safety and health of responders. Carbon monoxide is a colorless, odorless gas that can cause serious harm or even be fatal, as it binds to hemoglobin in the blood more readily than oxygen, effectively reducing the blood's ability to carry oxygen.

The specific level of 35 PPM (parts per million) is significant because it is recognized as a threshold where the risk of acute exposure becomes more pronounced. At levels above this concentration, individuals may experience symptoms such as headaches, dizziness, and confusion, which can impair their ability to operate effectively in hazardous environments.

Thus, when carbon monoxide levels exceed 35 PPM, it is advisable to don SCBA to protect against inhalation of toxic gases. The use of SCBA ensures that responders have a secure supply of breathable air, significantly mitigating the risks associated with carbon monoxide exposure.
