The existence of the potential for harm to public health resulting from a technological failure in any of fields of life, has stimulated in many of those fields a safety activity for preclusion of hazard situation. In retrospect, it appears that there is no Israeli law setting a safety criterion or directive which defines how to handle safety issues. Therefore, there is a significant difference in handling safety-related issues through the different fields.
In order to present a base for a possible common rule for risk-assessment in two fields, we examined the manner of treatment with respect to safety in terrestrial transportation and chemical industry in Israel.
In chemical industries with high risk potential, emphasis was placed on safety. Resources were exerted in order to develop methods for identification and techniques for control of risk factors early in the design phase.
The main conclusion of this work regarding the chemical industry is that a criterion for safety should be set by law, in order to ensure that this activity takes place in all companies.
In transportation, no activity takes place for identification of risk-factors during development of infrastructure. Safety activity focuses on the improvement of infrastructure in dangerous locations where many accidents occur.
Writing guidelines for transportation infrastructure design is the only safety-related activity performed with regard to the infrastructure development. These guidelines combine safety-oriented thinking in order to plan the infrastructure as a "forgiving-infrastructure". A safety expert was not involved and no action took place to identify risk factors in the design phase or upon design completion.
The work goal is to propose rule forming the base for qualitative and quantitative application. The rule shall be three-dimensional, as follows: Damage level, Risks types and Probabilistic criteria.
This work defines criterion for design of infrastructure as well as for the computation of risk level of driving on an existing highway, in a manner similar to that carried out in chemical industries.
The fundamental idea is to formulate a model which requires the engineers during the design phase and not in retrospect, after the occurrence of many accidents in dangerous locations.
No gap was identified which cannot be bridged in setting a criterion and carrying out a risk-assessment for both above mentioned issues.
The objective of this assessment is to identify the risk factors during those phases and to carry out preventive action for mitigation or minimization of the risks.
