I want to know what the "physical" counterpart to safety measures is called. An example: we take safety measures, such as securing our home from illegal entrance. This may take form of installing locks and alarms, but how would you refer to the physical implementations of these safety measures?
I understand safety measures as something abstract, referring to the idea of securing my home with a lock or an alarm. But if I'm about to talk, generally, of these installations taken as safety measures, what do I call them? Especially if the kind of safety measures taken is not fully known to me. I don't think "installing safety measures" or "disabling safety measures" are the proper way to describe the activity of installing alarms and locks, or disabling them.
EDIT: My example may have been a poor one, as it has been suggested that security measures is a better way of describing it that safety measures. I want to emphasize however that I am also interested in the physical counterpart to safety measures, as well as security measures (not restricted to alarms and locks, or even home security), if there is a difference. I suspect that security measures may be only one kind of safety measure, and that there may be other types of measures which may be characterized under the umbrella term of safety measures.
