We know confined spaces are challenging work environments. But have you ever wondered about the quality of air in these tight spots?
Oxygen, a vital component of the air we breathe, plays a pivotal role in such environments. Let’s delve into its significance.
What is a Confined Space?
A confined space is typically an area not intended for continuous human occupancy. It has limited entry and exit points, making regular tasks more challenging.
The Importance of Oxygen:
Air Composition: On average, the air we breathe contains about 20.9% oxygen.
Safety Thresholds: For any workspace, the safe oxygen concentration lies between 19.5% and 23.5% as per the international standards. Anything outside this range can be harmful. For Confined Space Rescue training contact us
Fluctuations in Oxygen Levels in Confined Spaces:
Decreases: Oxygen levels can fall due to rusting metals, microbial processes, fire or displacement by other gases.
Increases: Chemical reactions or processes releasing oxygen can lead to higher concentrations.
Potential Risks with Imbalanced Oxygen Levels:
Low Oxygen (Below 19.5%): Symptoms include difficulty in breathing, rapid heartbeat, clumsiness, unconsciousness even death.
High Oxygen (Above 23.5%): Elevates the risk of fire & explosion and may cause breathing difficulties.
Importance of Oxygen Monitoring and Training:
Monitoring Devices: Before entering into a confined space, it’s essential to use monitoring devices that measure oxygen levels. These devices ensure workers safety at the environment they’re stepping into.
Safety Training: Training equips individuals with knowledge about potential risks and prepares them with action plans for different types of emergencies. But still there are situations to maintain the oxygen levels to less than 5% in a confined space, a comprehensive training definitely can help the learner to understand how to work in those situations.
Conclusion and Takeaway:
The dynamics of oxygen levels in confined spaces are critical safety concern. Being aware, continually monitoring, and obtaining necessary training are essential steps to ensure your safety during the work. Get in touch with us for confined space entry training.
