A contractor finishes a shutdown repair, the equipment gets bolted back together, and someone hits start without checking whether the guards are back on or the isolation points are cleared. A pre-startup safety review exists to stop exactly that moment. This PSSR template gives cement plants a structured sign-off covering equipment readiness, safety verification, and documentation, so nothing restarts until every box is actually checked, not assumed. Sign up to run PSSR sign-offs through your own CMMS instead of a paper form.
Why It Exists
Most equipment incidents after maintenance work happen in the first few minutes of restart, not during the repair itself. A PSSR forces a deliberate pause between "the work is done" and "the equipment is running," so guards, isolations, and documentation get verified by someone other than the person who just finished the job.
Four Readiness Categories
Equipment Condition
Guards reinstalled, bolts torqued, lubrication topped up, no tools or debris left in the work area
Isolation Status
Lockout-tagout points confirmed removed only after every worker is verified clear
Safety Systems
Interlocks, emergency stops, and alarms tested and confirmed active before restart
Documentation
Work permits closed, redline drawings updated, and the maintenance record completed
The Sign-Off Chain
Maintenance Lead Confirms Completion
Verifies the physical work is finished and the equipment condition checklist is complete
Operations Verifies Isolation Removal
Confirms every isolation point is cleared and every worker is accounted for before power is restored
Safety Officer Tests Protective Systems
Checks interlocks, e-stops, and alarms respond correctly before the equipment is cleared to run
4
Shift Supervisor Approves Startup
Gives the final go-ahead once all three prior sign-offs are logged against the equipment record
Make Every Sign-Off A Recorded Step
Oxmaint lets each approver complete their part of the PSSR on a phone, with the equipment locked from restart until every sign-off is logged. Sign up for a free trial to build this sign-off chain into your own CMMS, or book a demo to see it on a live equipment record.
Skipping PSSR vs Following PSSR
| Moment |
Without PSSR |
With PSSR |
| Guard verification |
Assumed complete because the job is "done" |
Checked and signed off before power is restored |
| Isolation removal |
Left to whoever's near the switch |
Confirmed by operations only after everyone is clear |
| Accountability |
One person's word that everything is fine |
Four separate sign-offs recorded against the equipment |
| Incident investigation |
No record of what was checked before restart |
Full sign-off history available immediately |
The Payoff
A PSSR takes a few extra minutes before startup. Skipping it can cost a lot more than a few minutes if a guard is missing or an isolation point was never cleared. A structured template with four clear sign-offs makes the review fast enough to actually happen every time, not just when someone remembers.
Frequently Asked Questions
Q
When exactly should a PSSR be triggered?
A PSSR should run any time equipment is restarted after a shutdown, major repair, modification, or extended idle period, not just after large capital projects.
Q
Does one person's sign-off cover the whole review?
No, the review works best split across maintenance, operations, and safety roles, since each is checking a different failure point rather than one person confirming the entire restart alone.
Q
Can a PSSR sign-off be linked to the equipment's maintenance record?
Yes, in a CMMS the PSSR can be attached directly to the work order that triggered it, so the restart approval sits alongside the repair history for that same asset.
Never Restart Equipment On Assumption Alone
Oxmaint keeps equipment locked from restart until every PSSR sign-off is logged, so nothing runs until it's actually verified. Sign up for a free trial to build your own sign-off chain, or book a demo to see it working on your equipment.
