Reduce Risk
Avoid OSHA violations. Eliminate uncertainty that results in injuries and near misses. Lower insurance premiums.

Complete lockout context, integrated with your existing procedures
- 1
Check Out
A worker checks out a Smart Lock. It is now assigned to them.
- 2
Activate
The lock is placed at the isolation point, associating it with the equipment, and the lockout is recorded. Workers associated with that equipment receive a push notification that the equipment is now locked out.
- 3
Deactivate
When work is complete, the lock is removed, deactivating the lockout. The end time of the lockout is recorded and workers associated with the equipment receive a push notification that the lock has been removed.
- 4
Check In
The worker checks the lock in and it returns to the pool of available locks. The full timeline is preserved in the dashboard and reporting.
