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

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)

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 ...

New insights concerning intrinsic joint elasticity for safety

2010 IEEE/RSJ International Conference on Intelligent Robots and Systems, 2010
In this paper we present various new insights on the effect intrinsic joint elasticity has on safety in pHRI. We address the fact that the intrinsic safety of elastic mechanisms has been discussed rather one sided in favor of this new designs and intend to give a more differentiated view on the problem.

Intrinsic Safety at Underwriters' Laboratories

IEEE Transactions on Industrial Electronics and Control Instrumentation, 1973
The Underwriters' Laboratories has been investigating intrinsically safe equipment for use in hazardous locations for many years. It has recently published a Standard for Intrinsically Safe Circuits and Equipment, UL913. This presentation traces the development of the intrinsically safe requirements from the initial outlines to the printed Standard ...

SEPARATION FAULT SCENARIOS IN INTRINSIC SAFETY CIRCUITS

Environmental Engineering and Management Journal, 2019
The intrinsic safety type of protection significantly increased in complexity during the last decades. Thus, it even provides the opportunity to use highly complex electronic circuits without involving a significant explosion risk within the oil industry or in power plants, but not limited to those two. In order to achieve this performance, the type of

Evaluation of Systems for Intrinsic Safety

1966
Evaluation of a system, i.e., equipment and associated wiring, to determine whether it is intrinsically safe in accordance with the requirements of ISA Recommended Practice RP12.2, is not, and cannot be, a “cookbook” procedure. ISA RP12.2 adequately states the essential energy limitations and specifies the considerations of failure against which to ...

An intrinsic safety PLC with a graphic programming environment

IECON '98. Proceedings of the 24th Annual Conference of the IEEE Industrial Electronics Society (Cat. No.98CH36200), 2002
An intrinsic safety PLC has been developed. This PLC has been built to be used in dangerous environments, such inside mines, where there are risks of explosions. A MC68000 microprocessor has been used as the processor and the PLC incorporates a security system based on the use of fiber optics and the MC68HC11E2 microcontroller.

Intrinsic safety: explosion proof circuitry

IEEE Technical Applications Conference and Workshops. Northcon/95. Conference Record, 2002
When installing electrical circuits in hazardous locations, some form of explosion protection must be used in the United States and Canada. The traditional method has been to install these systems in explosion proof enclosures and sealed conduit. Since this type of production has proven to be expensive to install and maintain, many users have turned ...

IMPEDANCE SPECTROSCOPY ANALYSIS OF INTRINSIC SAFETY CIRCUITS

SGEM International Multidisciplinary Scientific GeoConference� EXPO Proceedings
The paper presents issues regarding impedance spectroscopy analysis for the identification of intrinsically safe circuits. The first part of the paperwork presents the explosion risk. In industrial applications, the presence of flammable substances leads to additional requirements for technical equipment used in such spaces.
