Primary containment requires using proper storage containers, good microbiological technique, and the use of appropriate safety equipment such as biological safety cabinets. Secondary containment is the protection of the environment external to the laboratory from exposure to infectious materials and is provided by a combination of facility ...
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 ...
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 ...
A physical hazard is an agent, factor or circumstance that can cause harm with contact. They can be classified as type of occupational hazard or environmental hazard. Physical hazards include ergonomic hazards, radiation, heat and cold stress, vibration hazards, and noise hazards. [1] Engineering controls are often used to mitigate physical ...
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.
Examples include high altitudes and unventilated, confined spaces. The OSHA definition is arguably broad enough to include oxygen-deficient circumstances in the absence of "airborne contaminants", as well as many other chemical, thermal, or pneumatic hazards to life or health (e.g., pure helium, super-cooled or super-heated air, hyperbaric or ...
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]
