Sommario/riassunto |
|
Do you have trips and safety interlocks in your plant? Are they good enough or are they perhaps over-designed and much more expensive than necessary? Are you or your company aware of how Hazard Studies should define risk reduction requirements? Are you actually using Hazard Studies at all?The answer is the integrated approach to safety management. New international standards combined with well-proven hazard study methods can improve safety management in your company.Practical Hazops, Trips and Alarms for Engineers and Technicians describes the role of hazard studies in risk managem |
