subject: The Importance Of Proper Confined Space Rescue Training [print this page] Although some confined spaces may not seem like a threat of danger, there are certain conditions within confined spaces that may not be apparent at first glance, such as sufficient oxygen levels, for example, or unstable surfaces. Confined space rescue involves special training and experience in order to rescue and recover victims trapped in restrained, hazardous areas. One of the first steps to understanding the importance of proper confined space rescue training is to learn what qualifies as a confined space and the potential dangers involved upon entering. Below, find a basic overview of confined space rescue.
What is a Confined Space?:
There are several characteristics that define a confined space. They include the limitations regarding entry, exit and accessibility, whether the space is large enough that an employee can enter and perform work, whether or not the space was meant to be occupied for long periods of time, and if there is sufficient ventilation in the space. Examples of confined spaces that are hazardous to workers include silos, railroad tans and chemical storage tanks. Confined spaces are also present in public areas, such as malls or swimming pools that have underground pumps and vaults that are rarely entered yet still pose a threat of danger.
The Dangers of Confined Spaces:
Confined spaces present many risks to any entrant, making prevention and rescue plans extremely critical should an accident occur. Spaces with small openings or walls that converge inward can trap entrants or limit accessibility to an entrance or exit. Another potential hazard involves the ventilation within confined spaces. Hazardous gases and vapors within small spaces, in addition to limited ventilation, are very dangerous and can lead to asphyxiation or explosions. Unstable surfaces, such as large piles of grain or sawdust, can suffocate victims if they become trapped. Besides the specific hazards related to confined spaces, more general hazards such as falling objects and slippery surfaces are also present.
Types of Rescue:
There are different types of rescue that can be used in confined space rescue. The rescue approach used depends on each specific case. Self-rescue is often the preferred method of rescue, as it provides victims with a plan of escape without putting other people at risk. However, self-rescue is not always possible, in which case non-entry rescue is the next approach. Non-entry rescue involves the use of rescue equipment and aids in recovering the victims. Some situations require entry rescue, which is when rescuers must enter the space.
Elements of a Proper Rescue Plan:
In the event that entry rescue is the only option, a rescue plan must be developed ahead of time in order to gather enough information about the victims and situation to safely recover the entrants. Rescuers must know where exactly the emergency is taking place and how many victims must be recovered. The cause of the accident is also vital information, as well as the length of exposure to the victims. Other important elements of a proper rescue plan include protective clothing, sufficient lighting, additional methods of ventilation, a standby rescue team, appropriate equipment for retrieving the victims, medical personnel, and clear communication at all times.
Understanding the appropriate procedures and reactions during confined space rescues requires extensive training and experience. If you or your workers are exposed to confined spaces on a regular basis, be sure to have access to a trained confined space rescue team and the necessary equipment.
