8 Common Mistakes in Using Breathing Apparatus
Breathing apparatus, such as self-contained breathing apparatus sets (SCBAs), are vital life-saving appliances on ships and in various hazardous environments. These devices are designed to protect users from inhaling harmful substances by providing a steady supply of breathable air. However, the effectiveness of these devices depends heavily on proper usage. Unfortunately, mistakes in using breathing apparatuses are common and can lead to serious consequences. This article highlights eight common mistakes in using breathing apparatuses and provides insights on how to avoid them.
1. Inadequate Training and Familiarization
One of the most common mistakes is the lack of proper training and familiarization with the breathing apparatus. Users often underestimate the importance of regular training, which leads to improper use during emergencies. SCBAs and other life-saving appliances on ships are complex devices that require users to be fully familiar with their operation. Regular drills and training sessions are crucial to ensure that users know how to don the apparatus correctly, operate it under stress, and handle any malfunctions.
2. Failure to Perform Pre-Use Checks
Before using a self contained breathing apparatus set, it is essential to perform a thorough pre-use check. This includes inspecting the equipment for any visible damage, ensuring the air cylinders are fully charged, and checking the seals and valves. Failing to conduct these checks can result in using faulty equipment, which can lead to equipment failure when it is needed the most. Always make pre-use checks a mandatory part of your routine to ensure the apparatus is in optimal working condition.
3. Incorrect Donning of the Apparatus
Donning the breathing apparatus correctly is critical to its effectiveness. A common mistake is not securing the face mask properly, leading to air leaks. This can allow toxic gases or smoke to enter the mask, compromising the user’s safety. It’s essential to follow the manufacturer’s instructions closely and ensure that the mask is fitted snugly, with no gaps. The straps should be adjusted evenly to avoid discomfort and maintain a proper seal.
4. Ignoring the Importance of Air Supply Management
Effective air supply management is crucial when using an SCBA, especially in environments where the air supply is limited. A common mistake is not monitoring the air gauge regularly, leading to an unexpected depletion of air. Users should be aware of the duration of their air supply and plan their activities accordingly. In high-risk situations, it’s essential to conserve air by controlling breathing and avoiding unnecessary movements.
5. Miscommunication During Operations
Communication is key during operations involving breathing apparatuses. A common mistake is the lack of clear communication between team members, which can lead to confusion and mistakes. Users should be trained to communicate effectively, using hand signals or communication devices designed for use with SCBAs. Establishing clear communication protocols can prevent misunderstandings and ensure a coordinated response during emergencies.
6. Neglecting Regular Maintenance and Servicing
Breathing apparatuses require regular maintenance and servicing to remain effective. A common mistake is neglecting this aspect, leading to equipment failure due to wear and tear. Regular maintenance includes checking for leaks, replacing worn-out parts, and ensuring that the air cylinders are serviced according to the manufacturer’s guidelines. Maintenance records should be kept up to date, and any issues should be addressed immediately.
7. Overconfidence in the Apparatus
Overconfidence in the breathing apparatus can lead to risky behavior. Some users may assume that wearing an SCBA makes them invincible, leading them to take unnecessary risks. It’s important to remember that while SCBAs are life saving appliances on ship and in hazardous environments, they have limitations. Users should always remain aware of their surroundings and avoid overextending themselves beyond what is safe, even when wearing an SCBA.
8. Failing to Consider Psychological Stress
Using a breathing apparatus in an emergency situation can be psychologically stressful. A common mistake is failing to prepare for the mental challenges associated with using the equipment under stress. Panic can lead to improper use, such as hyperventilation, which depletes the air supply more quickly. Regular training that simulates real-life scenarios can help users develop the mental resilience needed to remain calm and focused during emergencies.
Conclusion
Proper use of breathing apparatuses, such as self-contained breathing apparatus sets, is critical for ensuring the safety of users in hazardous environments. By avoiding common mistakes like inadequate training, failure to perform pre-use checks, incorrect donning, and neglecting maintenance, users can maximize the effectiveness of these life-saving appliances on ships and elsewhere. Understanding and addressing these common mistakes will help ensure that breathing apparatuses provide the protection they are designed to deliver.
