A supervisory system is a typical feature of an anti-collision system that covers an entire construction site. It allows a site supervisor to have a complete view of tower crane operations on a construction site. It also allows for centralised configuration and maintenance of the system. [2]
Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks. Construction is an often hazardous, predominantly land-based activity where site workers may be exposed to various risks, some of which remain ...
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
Deformation monitoring is primarily associated with the field of applied surveying but may also be relevant to civil engineering, mechanical engineering, construction, and geology. The measurement devices utilized for deformation monitoring depend on the application, the chosen method, and the preferred measurement interval.
In functional safety a safety instrumented system (SIS) is an engineered set of hardware and software controls which provides a protection layer that shuts down a chemical, nuclear, electrical, or mechanical system, or part of it, if a hazardous condition is detected.
The ATEX Directive has also adopted a functional safety standard, it is BS EN 50495:2010 "Safety Devices Required for the Safe Functioning of Equipment with Respect to Explosion Risks" covers safety related devices such as purge controllers and Ex e motor circuit breakers. It is applied by notified bodies under the ATEX Directive. The standard ...
Safety valves – Various devices that operate with fluids use fuses or safety valves as fail-safe mechanisms. Railway semaphore signals. "Stop" or "caution" is a horizontal arm, "Clear to Proceed" is 45 degrees upwards, so failure of the actuating cable releases the signal arm to safety under gravity.
When adding equipment is impractical (usually because of expense), then the least expensive form of design is often "inherently fail-safe". That is, change the system design so its failure modes are not catastrophic. Inherent fail-safes are common in medical equipment, traffic and railway signals, communications equipment, and safety equipment.
