It does, sometimes quite centrally, depending on which jurisdiction you are in. There is a well established principle of English law called "ALARP", which is short for "as low as reasonably practicable", and in English law the providers of equipment and services which are safety-related are required to reduce risks ALARP.
The ALARP principle is also used in other jurisdictions.
Reducing risks ALARP means, roughly, that risks must be reduced until the cost of reducing them further becomes "grossly disproportionate" to the benefits.
