why are confined space accidents rarely preventable

the Fatalities in confined spaces are most often the result of an atmosphere that is oxygen-deficient, toxic or combustible.1 According to the Bureau of Labor Statistics, 136 people in the United States died in accidents while working in confined spaces in 2015.2 For this reason, entering confined spaces requires very specific precautions. 0000186770 00000 n data. Nevertheless, they gave examples of a confined space that is enclosed on all sides such as a tank, or as few as two sides such as an enclosed conveyor.

In addition to these inhalation cases, there were 39 cases of depletion of oxygen and 21 cases of drowning. There are numerous reported cases where rescuers entering a confined space lost consciousness, making the entire rescue operation riskier and more complex. Confined spaces include tanks, vaults, pits, manholes, tunnels, equipment housings, pipelines, boilers, furnaces, compactors, sewers, attic spaces, and elevator pits.

Worker Deaths in Confined Spaces NIOSH Publication No. -Et1IYL[&3J0,ZOsUmwaung}Be? Confined space safety is the practice of ensuring safe work conditions in fully or partially enclosed areas such as manholes, pipelines, boilers, utility vaults, and storage bins. These hazards fall into two main categories hazardous atmospheres and safety hazards. Often defined as a space large enough for workers to enter, with limited or restricted means for entry or exit, and not designed for continuous occupancy, a confined space is connected to most of the potential risks found in places such as plants and manufacturing sites.

This is referred to as Apart from the OSHA criteria, confined spaces are defined across countries or regions as follows: Based on the definition of the National Institute for Occupational Safety and Health (NIOSH), a confined space refers to a space that, by design, has limited openings for entry and exit, unfavorable natural ventilation which could contain or produce dangerous air contaminants, and which is not intended for continuous worker occupancy. If the oxygen decreases to 6 to 10 percent, they will experience nausea, vomiting, loss of consciousness, and even death.
