In inherently safer design, the following concepts are used to reduce risk:
a) Reduction, e.g. reducing the hazardous inventoriesthe frequencyduration of exposure;
b) Substitution, e.g. substituting hazardous materials with less hazardous ones (but recognizing that there could be some trade-offs here between plant safetythe wider productlifecycle issues);
c) Attenuation, e.g. using the hazardous materialsprocesses in a way that s their hazard potential, such as segregating the process plant into smaller sections using ESD valves, processing at lower temperaturepressure;
d) All of them
Factors that will influence the ion of measures to reduce the risk include
a) Technical feasibility of the risk-reducing measure.
b) Contribution of the risk-reducing measure
c) Degree of uncertainty associated with the risk
d) Production time lost by implementing the measure (checklist, procedures…)

Jet fire is an ignition of a continuous leakage of flammable gasesvapours contained in pipescontainers with overpressure.
The probit equation is independent of the phenomena evaluated.
The Individual risk (or Cumulative Escalation risk) is the summation of risks all the outcomes affecting any locationis usually calculated on a grid
The screening criteria are the targetsstandards used to judge the tolerability of an identified hazardeffect.
The general hierarchy of risk-reducing measures is: prevention, detection, control, mitigation, emergency response.
BLEVE is suitable in atmospheric tanks
