Health hazards: When oxygen levels are too low, workers can experience dizziness, confusion, and loss of consciousness, which can lead to falls and other accidents. In severe cases, oxygen deficiency can cause permanent brain damage or death.

Fire and explosion hazards: In some industrial processes, the absence of oxygen can create explosive conditions. For example, in the presence of a fuel source and an ignition source, an oxygen-deficient environment can lead to a combustible mixture that can explode. This can result in injuries to workers, equipment damage, and production delays.

Production issues: Oxygen deficiency can also affect the quality and quantity of the final product. For example, in the production of metals, the absence of oxygen can lead to the formation of impurities that affect the strength and durability of the material. In other processes, oxygen deficiency can result in incomplete reactions or reduced yields, which can impact productivity and profitability.

Regulatory compliance: In some industries, regulatory bodies require the monitoring and reporting of oxygen levels as part of environmental or safety regulations. Failing to maintain safe oxygen levels can result in fines, penalties, and legal liabilities.
