Worked example
Opened with its default case — Number of employees issued with PPE: 30 · Safety helmet (EN 397) — weight %: Yes · Safety helmet (EN 397) — weight %: 0.25 — the calculator returns the figures below. The headline result is 458 pcs / year (total ppe pieces per year). They are written out here so the output is readable without running JavaScript: in print, with scripts disabled, or by a search engine.

How often does PPE need replacing?
There is no single interval, and any table that gives one without conditions is wrong. Replacement is triggered by whichever comes first of four things: the manufacturer’s stated service life in the instructions for use, which is a condition of the CE marking and therefore the governing figure; damage or contamination found at inspection; a single incident for impact and fall-arrest equipment, which are scrapped after one event regardless of appearance; and the end of a disposable item’s shift or task. The planning intervals in this calculator — helmets on about four years, footwear annually, gloves monthly, disposable masks and plugs per shift — are budgeting figures for a normal industrial environment, not a compliance schedule. Where the manufacturer states a shorter life, that figure wins.
What actually triggers a replacement
| Trigger | How it is detected | What it applies to |
|---|---|---|
| Manufacturer’s stated service life | The instructions supplied with the product; often a date of manufacture plus a period | All PPE — this is the governing figure and overrides any general table |
| Damage, wear or contamination | Pre-use check by the wearer, plus a periodic documented inspection | All PPE; the only trigger for items with no fixed life |
| A single incident | Reported at the time; the item is removed from service immediately | Helmets after an impact, harnesses and lanyards after arresting a fall, eye protection after a strike |
| End of shift or task | By design — the item is not intended to be reused | Disposable masks, disposable ear plugs, single-use gloves and coveralls |
Regulatory duties around PPE selection, provision, training and inspection differ by country. What is universal is the precedence: the manufacturer’s instructions for the specific product are the starting point, and no general interval overrides them.
Planning intervals for budgeting
For a budget you need an expected quantity per person per year. The defaults below are our own planning assumptions, not published norms — change them to match your own environment, which is the point of the input fields.
| Item | Typical standard | Quantity per person per year | What shortens it |
|---|---|---|---|
| Safety helmet | EN 397 | 0.25 (about one every four years) | UV exposure outdoors, any impact, visible crazing of the shell |
| Eye protection | EN ISO 16321-1 | 1 | Scratching from grinding or dust; a strike scraps it |
| Work gloves | EN 388 | 12 | Cut and abrasion exposure; chemical contamination |
| Safety footwear | EN ISO 20345 | 1 | Wet or oily floors, high walking distance, sole wear |
| Ear defenders | EN 352-1 | 0.5 | Hardening of the cushions; the seal, not the cup, sets the life |
| Disposable ear plugs | — | 220 (one pair per shift) | Nothing — they are single use |
| FFP2/FFP3 mask (NR) | EN 149 | 220 (one per shift) | Breathing resistance, dampness, any loss of face seal |
| Full body harness | EN 361 | 0.2 (about one every five years) | Any fall arrest scraps it; also UV and chemical exposure |
| Workwear | — | 2 | Laundry cycles; hi-vis loses retroreflection |
| Hi-vis vest | EN ISO 20471 | 1 | Washing degrades the retroreflective bands before the fabric fails |
The standard designations identify what to specify; the standards themselves are copyrighted documents and their requirement tables are not reproduced here. Marked on the product, they are also how you verify that a replacement is genuinely equivalent to what it replaces.
Items scrapped after one use
Two categories deserve to be separated from the rest, because reusing them is not a saving but a failure. Impact and fall-arrest equipment — helmets, harnesses, lanyards, energy absorbers — is designed to be destroyed by the event it protects against. A helmet that has taken an impact may look intact and have absorbed its capacity; a harness that has arrested a fall has stretched its absorber. Both are scrapped, and the way to make that happen is to have a replacement available so nobody has to choose between the rule and the job.
Disposables — NR-marked masks, foam ear plugs, single-use gloves — are the largest quantity line in almost every PPE budget and the one most often under-forecast, because they are counted per shift rather than per year. One pair of plugs per person per shift over 220 shifts is 220 pairs; budgeting “a few boxes” guarantees a mid-year shortfall.
Storage and shelf life
PPE ages in the store as well as in use. Filtering facepieces and chemical-protective gloves carry an expiry date and degrade in heat and humidity; helmet shells and harness webbing degrade under ultraviolet light, which includes daylight through a window. Two practical rules prevent most of the loss: store PPE in its packaging away from sunlight and solvent vapour, and issue oldest stock first so nothing expires on the shelf. Both of these also mean that buying several years of disposables to secure a discount is usually a false economy.
Records: what to keep and why
Whatever the local requirement, the same short record set answers every question that arises later: what was issued, to whom, on what date, and on what date it is due for review; the periodic inspection result for items that need one; and the manufacturer’s instructions for each product in use. Keeping the delivery notes and declarations of conformity with those records means the specification of what was supplied can be demonstrated rather than remembered.
What to send us for a quote
Send the calculator output with the size breakdown for footwear, gloves and workwear, and the hazards each group faces — cut level, chemical contact, noise level, work at height. Sizes and hazards are what turn a quantity list into a correct specification. We quote line by line with the standard designation stated for each item, supply the declarations of conformity, and can schedule deliveries so consumables arrive against usage rather than in one lot that ages in the store.
Frequently Asked Questions
How often should a safety helmet be replaced?
Follow the manufacturer’s stated service life in the instructions supplied with it — commonly a period from the moulding date, which is stamped inside the shell. About four years is a normal planning assumption for budgeting, but any impact scraps the helmet immediately regardless of age, and UV exposure outdoors shortens the life.
Can a harness be reused after arresting a fall?
No. Fall-arrest equipment is designed to absorb the energy of one event; the energy absorber has deployed and the webbing has been loaded. Remove it from service immediately, and keep a replacement in stock so the rule is never in competition with the work.
How many disposable masks should I budget per person?
One per shift for an NR-marked FFP2 or FFP3 — about 220 a year on a normal shift pattern. Masks are also discarded within a shift when breathing resistance rises, when they become damp, or whenever the face seal is broken, so the real figure is usually a little higher.
Do hi-vis garments wear out before they look worn out?
Yes, and this is the common failure. The retroreflective bands degrade with washing well before the fabric does, so a vest can look serviceable and no longer perform. Manufacturers state a maximum number of wash cycles — treat that as the life, not the appearance of the garment.
Does PPE expire in storage?
Filtering facepieces and chemical-protective gloves carry expiry dates, and helmet shells and harness webbing degrade under ultraviolet light including daylight. Store in packaging out of sunlight, issue oldest stock first, and be cautious about bulk-buying disposables far ahead of use.
Can you supply PPE with the conformity documents?
Yes. Every item is quoted with its standard designation and supplied with the declaration of conformity, so the specification of what was delivered can be demonstrated rather than remembered. Send the calculator output with the size breakdown and it comes back within one business day.
