Hasps

A hasp lets several people lock one isolation point. The hasp goes through the lockout device or switch; each worker adds their own padlock to one of its holes, and the point stays locked until the last padlock is removed. The Safety Hasp with steel hasp and nylon body takes six padlocks and is the standard choice; the Safety Hasp in nylon has a non-conductive body for electrical work.

Steel for strength and everyday use: the Safety Hasp with steel body resists cutting and weather. Aluminium is lighter and does not spark, which matters in ATEX zones: the Safety Hasp in aluminium. Nylon does not conduct and does not scratch painted panels: the right hasp for switchgear. All three take the same padlocks, with a 25 mm or 38 mm jaw depending on the lockout point.

A hasp works when the group is small and everybody can reach the isolation point. When one job has many isolation points, or the team changes over shifts, lock each point with one padlock, put those keys in a lockout box and let every worker add their padlock to the box. Hasps with a thick shackle, like the thick-shackle padlock hasp, fit the larger holes on boxes and stations.
