Concerns of the hazardousness of lithium sulfur oxide batteries waste were raised as lithium batteries become more obtainable.

The hazardousness of battle plans requiring precise coordination of widely separated elements had been a military truism even on pre-spaceflight Earth, before anyone could have imagined a separationthis wide.

The implications for GIS in the development of 'hazardousness' indices are obvious and if time-series data are available there is the potential to produce a variety of probability maps.

Can we not use GIS technology to construct 'risk mosaics'(Zeigler et al.1983), at a variety of spatial scales, akin to Hewitt and Burton's 'hazardousness' of a place?

Take the example of the regulation on authorisation. We are in the process of banning entire clusters of active substances on the basis of exclusion criteria, simply because of an abstract notion of hazardousness.
