How Much Disposable PPE Does a Food Plant Use?

Procurement teams asking for a quote are usually asked the same first question: how many do you need per month? Most plants do not know offhand, and guessing leads either to stock running out or to cartons piling up. The good news is that a usable estimate takes ten minutes and a spreadsheet. This guide shows a simple method and a worked example. The numbers in the example are illustrative only; replace them with your own.

The basic formula

For each PPE item, monthly consumption is the number of people who use it, times the number of times each person changes it in a day, times the number of working days in the month. Then add visitors and a buffer.

1. People: count by zone, not for the whole site, because not everyone uses every item.
2. Changes per day: one at the start of the shift, plus replacements after breaks, damage and zone changes.
3. Working days: for example 22 for a five-day week, or more for continuous operations.
4. Visitors and contractors: estimate a typical week and scale it to the month.
5. Buffer: add roughly 10 to 15 per cent for damage, spills and growth.

A worked example

Imagine a plant with 100 people working in production on a single shift, five days a week. These figures are examples only.

With a 12 per cent buffer, the hair net figure becomes about 3,700 per month, and the same logic applies to the other lines. Visitors come on top: ten visitors a week with a hair net, gown and shoe covers each adds roughly 40 sets a month.

Where estimates go wrong

• Counting the whole site's headcount for items only used in one zone.
• Ignoring breaks, which often double the number of changes.
• Forgetting seasonal peaks, cleaning shifts and temporary staff.
• Ordering by price per carton without checking pieces per carton, so the stock lasts half as long as planned.

Buffer stock and reorder points

Work out the average daily use, then multiply by the lead time in days, including delivery. Add a safety margin on top. When stock falls to that level, it is time to reorder. For a plant using 150 hair nets a day with a 14-day total lead time, the reorder point would be 2,100 plus a safety margin. The point is to reorder before running low, not after. Lead times for a specific supplier should be confirmed in writing; see the Buyer's Guide.

Check against reality

After the first month, compare the estimate with actual use and adjust. Track by zone where you can, which also shows where colour-coding or training needs attention. For the zone side, see Colour-Coding Disposable PPE by Zone.

Getting a quote that fits

When you send a request to a supplier, include item, size, colour, estimated monthly volume and delivery destination. Disponord manufactures and exports disposable hair nets, beard covers, aprons, sleeve covers, shoe and boot covers, visitor gowns and coveralls, and you can send your figures through the quote form.
