Environmental gas displacement Confined spaces, combined with accidental gas leaks, such as mines, [1] submarines, [2] [3] refrigerators, [4] or other confined spaces [5] Fire extinguisher systems that flood spaces with inert gases, such as computer data centers and sealed vaults [4]
A confined space is a space with limited entry and egress and not suitable for human inhabitants. Alternative names for a confined space are enclosed space and dangerous space. [1] An example is the interior of a storage tank, occasionally entered by maintenance workers but not intended for human occupancy.
These shafts are typically placed at regular intervals along the tunnel to ensure that airflow reaches all parts of the mine. This distribution of airflow is essential for diluting hazardous gases, such as methane and carbon monoxide, which can accumulate in confined spaces and pose serious risks of explosion or poisoning.
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.
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.
In some of the most hazardous conditions, SCBAs can be worn in conjunction with gas tight suits, which also aids in decontamination procedures. In the industrial setting, especially in confined spaces, a user will often be supplied air through a pressurized airline and will only carry compressed air cylinders for emergency escape and ...
The Minnesota Department of Public Safety State Fire Marshal (SFM) determined that the 100-pound propane cylinder, which was believed to be empty, contained enough leftover gas to fill the storage ...
A utility vault is an underground room providing access to subterranean public utility equipment, such as valves for water or natural gas pipes, or switchgear for electrical or telecommunications equipment. A vault is often accessible directly from a street, sidewalk or other outdoor space, thereby distinct from a basement of a building. [1] [2]
