Safety studies performed during the various stages of the conceptual design of IFMIF have been brought together in a preliminary assessment of the safety of IFMIF, identifying the principal hazards and the means to prevent or mitigate them.
We have taken into account this fundamental distinction to develop a volcanic-hazards zonation (for lava flows and ash fall only) that includes: definition of the principal hazards; identification of the areas that have higher probability of containing emission centres; and numerical modelling of the vulnerable areas to be affected by volcanic hazards.
It is used as an ingredient in red signal flares and phosphors and is the principal health hazard in radioactive fallout.
In three cases, the principal potential hazard of the substitutes is acute eye, skin and/or respiratory irritation.
The influence of the principal risk factors on prognosis were studied and their effect adjusted using a multivariate analysis based on the Cox proportional hazards model.
Whilst the database currently focuses only on large magnitude eruptions, it will be expanded to include data specifically relating to the principal volcanic hazards (e.g. pyroclastic flows, tephra fall, lahars, debris avalanches, ballistics), as well as vulnerability (e.g. population figures, building type) to facilitate risk assessments of future eruptions.
The medical literature published following the 9/11 attacks and other international terrorist incidents has illustrated several principal immediate hazards and long-term consequences.
All market failure mechanisms deserve careful study and respect - externalities, moral hazard, principal-agent problems, market domination, asymmetric information and, I would add, group-think.
A second recommendation that could increase lab worker's ability to improve their own safety calls for "the researcher and principal investigator [to] incorporate hazard analysis into laboratory notebooks prior to experiments, integrate hazard analysis into the research process, and ensure that it is specific to the laboratory and research topic area".
The Peak Ground Acceleration (PGA) is the principal measure of seismic hazard, the Peak Ground Displacement (PGD) represents secondary impacts, and land-use patterns characterize urban vulnerability.
