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.
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.
Discharge flow: The amount of water flowing from a fire hydrant when it is opened; compare to static flow and residual flow. Determinate: (Response determinate) The level and type of response needed based on information provided by a caller reporting an incident. Often utilizing a structured questioning flow chart or algorithm.
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.
These are systems used to supply breathing gas on demand in a chamber which is at a pressure greater than the ambient pressure outside the chamber. [1] The pressure difference between chamber and external ambient pressure makes it possible to exhaust the exhaled gas to the external environment, but the flow must be controlled so that only exhaled gas is vented through the system, and it does ...
The use of lockout–tagout is not currently enforced in the UK but has been proven to be best practice for multiple UK industries. BS7671:2008 is a regulation in the UK that ensures that all wiring and electrical installations completed within any building is of the highest standard. It also states that "Every employer shall ensure that where ...
A manhole (utility hole, maintenance hole, [1] or sewer hole) is an opening to a confined space such as a shaft, utility vault, or large vessel. Manholes, typically protected by a manhole cover, are often used as an access point for an underground public utility, allowing inspection, maintenance, and system upgrades.
In confined spaces, common in urban warfare, even the operators themselves may be at risk due to deflection of backblast by walls or sturdier civilian vehicles behind them. Soft launch methods diminish backblast by ejecting the projectile some distance before its main rocket motor ignites. Backblast can also be reduced by adding a countermass ...
