Lockout Hasps are integral to a successful safety lockout program or procedure as they can provide effective multi-person lockout. Multiple padlocks can be applied to Lockout Hasps, this allows an energy source to be isolated by more than one worker. This means that the energy source is completely locked out and can’t be operated until each worker unlocks their padlock from the hasp.

Lockout Hasps clip on to several different areas of a hazardous energy source, ensuring that it can’t be switched on (LOCKED OUT) and tagging it visually (TAGOUT). By clearly marking the lockout hasp with a date and name and attaching a padlock to the hasp, the hasp is efficiently used in a successful safety lockout program.

Our hasps are available in several different sizes which means that workers can effectively isolate any energy source required. Padlocks applied to the hasp can be colour-coded depending on which engineer has the key, this will mean added safety.
