  In­ter­locks are an im­por­tant fea­ture of both per­son­nel and ma­chine pro­tec­tion sys­tems for mit­i­gat­ing risks in­her­ent in op­er­a­tion of dan­ger­ous equip­ment. The pur­pose of an in­ter­lock is to se­cure spe­cific equip­ment or en­tire sys­tems under well de­fined con­di­tions in order to pre­vent ac­ci­dents from hap­pen­ing. De­pend­ing on spe­cific re­quire­ments for the level of re­li­a­bil­ity, avail­abil­ity, speed, and cost of the in­ter­lock, var­i­ous tech­nolo­gies are avail­able. Dif­fer­ent ap­proaches are dis­cussed, in par­tic­u­lar in the con­text of per­son­nel safety sys­tems, which have been built or tested at CERN dur­ing the last few years. Tech­nolo­gies dis­cussed in­clude ex­am­ples of pro­gram­ma­ble de­vices, PLCs and FPGAs, as well as wired logic based on re­lays and spe­cial logic cards.
