Which of the following is a reason to always check for oxygen levels in confined spaces?

• A. To ensure proper ventilation
• B. To prevent chemical burns
• C. To avoid asphyxiation
• D. To detect equipment failures

Answer: (C)

Checking for oxygen levels in confined spaces is essential primarily to avoid asphyxiation. In such environments, the concentration of oxygen can become significantly lower than acceptable levels, posing a serious risk to anyone entering the space. Oxygen is crucial for human survival; a lack of it can lead to unconsciousness or even death within minutes. By ensuring there is enough oxygen before entering a confined space, workers protect themselves from this critical hazard. While ensuring proper ventilation is important and can relate to maintaining healthy oxygen levels, the primary focus must be on the specific dangers associated with inadequate oxygen, such as asphyxiation. Other factors like chemical burns or equipment failures are concerns in confined spaces but do not directly relate to checking oxygen levels as a primary concern. Ensuring sufficient oxygen levels is fundamental in maintaining a safe working environment in confined spaces.
