Confined space training outlines the skills and protocols for safe entry to confined spaces, and includes precautions such as locking and tagging out connecting piping, testing of breathable air quality, forced ventilation, observation of workers in the space, and a predetermined rescue plan with appropriate safety harnesses and other rescue ...
The Occupational Safety and Health Administration (OSHA) regulation (1910.134(b)) defines the term as "an atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or would impair an individual's ability to escape from a dangerous atmosphere." [2]
Confined space rescue is a subset of technical rescue operations that involves the rescue and recovery of victims trapped in a confined space or in a place only accessible through confined spaces, such as underground vaults, storage silos, storage tanks, or sewers. A warning label on a storage tank, indicating that it is a confined space.
Only where elevated concentrations of asphyxiant gases displace the normal oxygen concentration does a hazard exist. Examples are: Environmental gas displacement Confined spaces, combined with accidental gas leaks, such as mines, [1] submarines, [2] [3] refrigerators, [4] or other confined spaces [5]
Hazards like entrapment and drowning to asphyxiation and toxic chemical exposure results in the deaths and injuries that occur in these confined spaces. [16] Physical and atmospheric hazards due to confined spaces can be avoided by addressing and recognizing these hazards before entering in the confined spaces to perform work. [17]
Over time immunodeficiency results in the rapid spread of infection among crew members, especially in the confined areas of space flight systems. On 31 May 2013, NASA scientists reported that a possible human mission to Mars [ 56 ] may involve a great radiation risk based on the amount of energetic particle radiation detected by the RAD on the ...
Astronautical hygiene evaluates, and mitigates, hazards and health risks to those working in low-gravity environments. [1] The discipline of astronautical hygiene includes such topics as the use and maintenance of life support systems, the risks of the extravehicular activity, the risks of exposure to chemicals or radiation, the characterization of hazards, human factor issues, and the ...
An inerting system decreases the probability of combustion of flammable materials stored in a confined space. The most common such system is a fuel tank containing a combustible liquid, such as gasoline, diesel fuel, aviation fuel, jet fuel, or rocket propellant.
