A new, electronic method for intrinsic safety testing [PDF]

, 2011
Intrinsic safety testing is a method for ensuring that electrical apparatus designed to be used in explosive environments will not provide enough energy to cause an explosion. Under the current international standard an apparatus that is being tested for intrinsic safety is connected to a test device called "Spark Test Apparatus" (STA).

Intrinsic Determinants and Harmonic Measure of Flight Safety

IEEE Transactions on Industrial Electronics, 2020
Awareness of the approaching hazards and assessment of the potential risks are indispensable to continually defend the safety of flight. Hazard identification and risk management involve various aviation events and assessment criteria. A unified mechanism of transforming domain, whereby safety factors are summed up in three intrinsic determinants, was ...

Intrinsic Safety Rules Ok

IFAC Proceedings Volumes, 1985
Abstract The technique of intrinsic safety was originated in England for mine signalling during 1914-16, and is now the predominant solution for process measurements and control in hazardous locations. 1 This paper reviews its basic principles and advantages.

Safety—intrinsic or invulnerable?

Electronics and Power, 1971
Chemical plants and oil refineries rely heavily on electrical and electronic control systems for efficient operation. The techniques by which the safe operation of these systems is ensured is presently undergoing international discussion, although the safety-barrier technique seems to provide invulnerable rather than merely intrinsic safety.

Intrinsic Safety Analysis - Driving Safety Performance to a New Level

Proceedings of IADC/SPE Drilling Conference, 2006
Abstract Safety performance in the drilling industry continues to pose a major challenge to both Contractors and Operators. Historical accident rates, while lower than they were a decade ago, remain at unacceptably high levels despite intense focus by all stakeholders, and the use of a wide range of safety systems.

Intrinsic Safety International Standards

IEEE Transactions on Industrial Electronics and Control Instrumentation, 1973
International Electrotechnical Committee SC31G has been working for several years on a recommendation to cover the requirements for intrinsic safety. The Committee is nearing the completion of the document. Detailed requirements will differ from several of the existing national standards.

Intrinsic safety - the way forward

Fifth International Conference on `Electrical Safety in Hazardous Environments', 1994
This paper discusses the position of intrinsic safety and low power systems in the context of CENELEC. It avoids discussing the impact of possible EC directives which at the time of writing this paper (November 1993) have not been finalised. In the authors opinion unless these directives are considerably modified then it is impossible to be optimistic ...

Intrinsic Safety for Hazardous Area

2009
It is vital need to apply safety measures to the electrical apparatus used in explosive atmosphere as this impedes any damage to the property as well as reduces the risk of life of the workers on duty (Adams, 1990, 1991). There are various protection concepts deployed in sensitive and potentially explosive atmospheres. Among these, intrinsic safety (IS)

Intrinsic road safety: A new approach?

Safety Science, 1995
In 1991 the Dutch Ministry of Transport, Public Works and Water Management concluded that its policy regarding road-safety should be sharpened in order that its goal set for road-safety in the year 2010 would be achieved (i.e. 50% reduction of dead and 40% reduction of wounded persons in comparison with 1986). This new policy is being called “Intrinsic

Protection by intrinsic safety

1994
In conclusion, it will be seen that protection by the method of intrinsic safety has grown rapidly due to its eminent suitability for very low voltage, low power process control and information transfer installations. It differs from other types of protection for electrical apparatus in potentially explosive atmospheres because the flow of energy from ...
