Mutual Aid and Spare Edge Sharing Between Neighbouring Depots

Scenario: a depot runs short of edges mid-season and a neighbouring depot has some on the shelf. Direct answer: agree the rules in advance: what each side lists, how a request is made, how parts are returned or paid for, and who signs. The checklist below is for operational planning and does not replace your agency’s legal and procurement rules.

Checklist

Agree what is shared

• [ ] List edge types, sizes and mounting patterns each depot holds.
• [ ] Add bolts, shoes and other parts you may share.
• [ ] Agree what is not shared, for example the last spare of a critical size.

Agree how to ask

• [ ] Name a contact at each depot, with a backup and phone numbers.
• [ ] Agree what information a request carries: part, quantity, truck, time needed.
• [ ] Agree who decides when stock is low on the lending side.

Agree how to exchange

• [ ] Who delivers or collects, and how fast?
• [ ] How the parts are inspected on handover.
• [ ] Whether they are returned in kind, replaced later or paid for.

Agree how to record

• [ ] A simple form for each transfer, signed by both sides.
• [ ] A shared log of transfers by date.

Agree the formalities

• [ ] Check with procurement and legal what the rules say about transfers between agencies or entities.
• [ ] Put the agreement in writing and review it each year.

Test it

Run a short exercise: one depot requests a part, the other responds, and both fill in the form. Note how long it took and what slowed it down.

A short written agreement

Even a one-page memorandum helps: names, contacts, what is shared, how requests work, how returns are handled and when it is reviewed. Keep it simple enough that supervisors read it, and attach the transfer form so that nobody needs to invent one on the day.

Common problems to plan for

Mutual aid tends to fail on small points: the wrong bolt pattern arrives, nobody answers the phone at night, or the lending depot discovers it needed the part. Agree a rule that the lender keeps a minimum, list the contact for nights and weekends, and mark parts with truck types. Run the practice request in calm weather so these problems appear before the storm does.

Boundary: This is not legal or procurement advice; rules on transfers between agencies or entities vary, so check with your own legal and procurement staff.
