Lockout Hasps

A lockout hasp lets several workers lock a single isolation point at the same time. Each worker fits their own padlock through a hole in the jaw, and the hasp cannot be opened until every lock is removed.

This depends on the hasp. The stainless steel tamper proof hasp takes up to seven padlocks. Vinyl coated hasps vary by size, so check the hole count against the maximum crew locking onto that isolation point.

Both hold multiple padlocks on one isolation point. The stainless steel hasp is tamper proof, takes seven locks and resists corrosion. The vinyl coated hasp suits routine duty and comes in more than one jaw size.

A tamper proof hasp is built to resist being defeated or slipped off while locks are fitted. This matters on isolations left in place across shifts, or anywhere unauthorised interference is a credible risk.

Jaw opening decides whether the hasp will close over the isolation point at all. Measure the handle, lever or isolator first, because a hasp that does not close on the point is unusable at that location.

Hasps can be linked to carry more locks than one hasp holds, where the site procedure allows it. This suits large crews working on a single isolation. Confirm the arrangement is permitted before relying on it.

Not necessarily. A single worker can often apply a padlock directly if the isolation point accepts one. A hasp is needed when the point will not take a padlock directly, or when more than one lock must fit.

The vinyl coating protects the jaw and the surrounding equipment from marking and scuffing, and improves grip when handling the hasp. It is the general duty choice for routine isolation work across most sites.

Yes. Group isolation is standard on mining shutdowns, where several trades lock onto the same point. Stainless steel suits corrosive and high wear conditions, while vinyl coated suits workshop and plant duty.

A lockout hasp is one device within a documented lockout tagout procedure. The procedure sets who isolates, how energy is verified as isolated, and the order in which locks and tags are applied and removed.
