A blast furnace shutdown gives you a fixed number of hours to do work that took weeks to plan, and every hour lost to a missing spare part, an unsigned permit, or a contractor standing around is an hour the furnace stays cold. A pre-shutdown work pack turns that scramble into a sequence, with every task, part, and permit locked in before the furnace ever comes down. This free template lays that sequence out end to end. Sign up to build your next shutdown work pack inside OxMaint.
Why A Work Pack Matters
Without a work pack, shutdown planning happens in someone's head and a stack of emails. Spare parts get ordered late, contractor scope gets argued over on-site, and permits get signed the morning of instead of days ahead. Every one of those gaps eats directly into furnace downtime that was never supposed to happen in the first place.

Critical Path Schedule
The longest chain of dependent tasks that sets the minimum shutdown length
Safety & LOTO Sign-Offs
Isolation points and permit sign-offs tracked task by task, not on paper
Post-Shutdown Punch List
Open items and deferred jobs carried forward to the next planned outage
The Shutdown Countdown
Spare parts ordered, contractor scope finalized
Critical path schedule locked, permits drafted
Parts staged on-site, crews confirmed and briefed
Permits and LOTO sign-offs completed, final walkthrough
Work executed against the sequenced task list in real time
Restart complete, punch list logged for next outage

Frequently Asked Questions
Q
How far in advance should a blast furnace shutdown be planned?
Most plants start locking scope and ordering long-lead spare parts around 30 days out, with the critical path schedule and permits finalized in the final one to two weeks before the furnace comes down.
Q
What is the critical path and why does it matter for shutdown length?
The critical path is the longest chain of tasks that depend on each other in sequence. It sets the shortest possible shutdown length, so any delay on a critical path task delays the entire restart.
Q
What happens to tasks that don't get finished during the shutdown window?
They roll onto the post-shutdown punch list with the reason logged, so they carry forward as a known priority for the next planned outage instead of getting forgotten.
