What must be done with oxygen levels when preparing to enter a confined space?

When preparing to enter a confined space, it is crucial to test and monitor the oxygen levels to ensure the safety of individuals entering the area. Confined spaces can present various hazards, including the potential for oxygen deficiency or enrichment, which can lead to dangerous situations such as asphyxiation or fire. Monitoring the oxygen levels helps determine if the environment is safe for entry and whether additional ventilation or precautions are necessary.

By regularly testing the atmosphere for oxygen concentration, a team can assess the need for further safety measures, such as supplying supplemental oxygen or implementing appropriate ventilation to maintain a safe working environment. This proactive approach is essential to comply with safety regulations and protect the health and safety of personnel involved in confined space work.
