heal.abstract	The management of hazards and risks associated with the inherent characteristics of chemicals constitutes one of the biggest challenges of our modern world. Relative ranking and hazard indices are among the widespread hazard assessment techniques. In this paper, a new approach for the relative hazard assessment is introduced, treating the issue as a multi-criteria decision making problem, as quite often more than one parameters, or criteria, should be taken into account. Based on this approach, a methodology has been developed, aiming at the rapid assessment and relative ranking of chemical hazards, employing a multi-criteria technique, the Analytic Hierarchy Process, AHP, and also Fuzzy Logic as a more efficient tool in handling both linguistic variables and uncertainties present in hazard assessment. Using the proposed methodology, a number of hazard indices have been developed and are presented: The Substance Fire Hazard Index, proposed as a tool for the relative ranking and assessment of chemicals based on their fire hazard properties, the Substance Toxicity Hazard Index, introduced as a screening / relative ranking tool of toxic substances, and the 'Consequences Index', for ranking installations based on their 'consequences potential', the consequences that would result from the worst case accident scenario (fire, explosion, toxic release) at an installation that uses, produces, stores hazardous materials. Finally, the challenges and limitations of using the multicriteria approach for the development of relative ranking and assessment indices are also discussed.	en
