It is important to note that the Confined Space Entry is a broad topic that is discussed as the entries differs from time to time even if the equipment used is the same. The same unit can be used to make the entry even though this depends on each occasion. The confined areas are known to contain gases which can catch fire, reduced oxygen levels and gas leakage among other harmful substances. It is easy to suffocate due to the state found in some of the confined areas. Therefore, a permit is needed as per the Confine Space regulations to ensure the safety of the crew entering such places. Motion is limited while inside the confined spaces regardless of their size. Due to the health issues associated with the confined spaces, it is essential to avoid working for extended hours.
The vaults, pits, storage bins, tanks, vessels and storage bins are some of the areas which are classified as confined. A worker who is working in any of the enclosed spaces is expected to learn the hazards they are exposed to as each confined space is associated with specific risks such as flammable gases and other toxins. If you are working in an area with excess oxygen or reduced oxygen content, then you are going affect your wellness. If you are in cramped places, you may suffer from suffocation due to lack of air.
It is hard to operate from the outer areas of a confined space, but it is recommended to use the external areas for health reasons. The employees are expected to establish facilities which they are using to operate and permit space entry programs are required to monitor entry into the confined spaces. The areas regarded as confined are supposed to have signs that the work is going on, and when an accident occurs, the permit which is in writing is used to determine the people using the location. You are supposed to use the signs to know if the space is operational and whether you need a permit to enter them.
The workers are trained well before using the confined areas with several posts being distributed which consist of entrant attendant. If you are trained to become an entrant supervisor, then you will be expected to determine the safety of the confined area as well as terminating the operations taking place. Three atmospheric tests are carried by the entrant supervisor on the location where the hazardous activity will take place. The tests are done in a specific order which is, determining the level of oxygen, checking if there are flammable gases and pointing out to contaminants especially the hazardous one.
The percentage of oxygen should range between 19 and twenty-three and a half to allow the person in the confined place to breathe quickly and also to avoid the case where the level is high to activate explosion or fire from the flammable gases and vapors.
