Buyer question

Should edge and spare-parts stock be part of our snow emergency plan, and what minimum stock, owners and trigger points should it name?

Main answerSENTHAI Editorial Team

Main answer

Short answer
Yes, as a readiness item, since a plan that assumes trucks can keep plowing is exposed if edges run short in a long event. The plan should state minimum stock, who counts it, when it is counted and what happens at a trigger point. I do not cite any plan or standard; this is a planning guide to adapt to your own emergency documents.

What a plan should say about stock

Element Example wording to adapt
Minimum stock Each depot holds at least [N] sets of edges per truck type and [N] sets of hardware
Count date Counted before the season and before each forecast event
Owner Named role responsible for the count and for ordering
Trigger point When stock falls below [N], order and notify the manager
Fallback Share stock between depots; use mutual aid; prioritise routes
Supplier contacts Names, numbers and after-hours contacts for edges and hardware
Record Log of use during the event

The bracketed numbers are placeholders for you to set from your own usage records.

Readiness checklist

The readiness check is done before the season, when fixes are still possible.

  1. Count edges and hardware per truck type and compare with the minimum.
  2. Check that spare edges fit the trucks currently in service.
  3. Check tools and lifting gear for changing edges.
  4. Check that the call list and supplier contacts work.
  5. Check that crews know how and where to swap an edge.
  6. Agree who decides to move stock between depots.

Trigger points

Triggers turn a plan into an action without a meeting.

  • Forecast of a long or severe event: count stock and top up.
  • During the event: log use per shift and compare with the minimum.
  • After the event: restock and review.

How to set the minimum

Use your own records: the number of edges used in your heaviest recent week, plus a buffer. If you have no records, start with a simple estimate and revise after the first season.

Limits

No official requirement is cited. Check your own emergency plan and any rules that apply to your agency or contract.

Boundary: No official requirement is cited and the bracketed numbers are placeholders; adapt the wording to your own emergency plan and rules.

Set minimum stock from your own heaviest recent week, then agree reorder triggers with suppliers. Keep after-hours contacts current and test them before the season. Record usage during events so that next year’s minimum rests on data. Make sure the plan says who can approve emergency purchases and up to what amount.

Count stock before the season and before every forecast event. Check that spares fit trucks currently in service, and that lifting gear and tools are in place. Practise an edge swap with a crew, and record the time. After the event, restock and write down what ran short, so that the plan improves each year.

Field-check perspective

↳ Replying to Maintenance perspective

Walk the depot shelves with the plan in hand and count by eye against the system. Look for damaged or mislabelled stock. Check that the call list works by ringing the numbers. If the plan says stock can move between depots, check who has the key and the vehicle to move it, since plans often fail at that detail.
