PPE Replacement Intervals: How Often Should Each Item Be Renewed?

In most businesses PPE is bought "when it runs out". Yet much PPE doesn't run out — it ages: a hard hat consumes its life even sitting in a cupboard, a harness is scrap after a single fall, an FFP respirator has done its job by the end of the shift. Knowing replacement intervals underpins both legal compliance and a sane purchasing plan.

Framing that matters: under Türkiye's Occupational Health and Safety Law no. 6331 and the PPE regulations, providing suitable equipment, tracking its life and replacing expired items is the employer's duty. The intervals below reflect common manufacturer declarations and field practice; what binds you is the manufacturer's declaration for the exact product you use.

Typical service lives, item by item

Hard hats

For industrial helmets (EN 397) manufacturers commonly recommend 3-5 years from the date of manufacture — some split it as "3 years in use, up to 2 in storage". The moulding date is stamped under the brim; it's the first thing an auditor checks. UV, sweat and heat shorten life. Any helmet that has taken an impact is replaced immediately, visible damage or not. Renewing the inner harness yearly is a cheap, common reinforcement.

Safety eyewear and face shields

A scratched lens degrades both vision and protection class — replace on scratching. In heavy use, practical life runs 6 months to 2 years; anti-fog coatings weaken with each wash.

Respiratory protection

FFP1/FFP2/FFP3 filtering half masks are single-shift items; anything marked "NR" (non-reusable) doesn't carry to the next day. Reusable half/full-face masks last years, but filters and cartridges have both shelf life and in-use limits — once opened, manufacturers typically want them consumed within 1-6 months.

Gloves

For mechanical-protection gloves (EN 388) the calendar is irrelevant — wear decides: puncture, thinning, opened seams → replace. On busy sites that's a matter of weeks, so plan gloves by monthly consumption norm, not by piece. For chemical gloves (EN 374) the manufacturer's permeation/breakthrough time per chemical is what counts — past it, an intact-looking glove no longer protects.

Hearing protection

Foam earplugs are single-use. On earmuffs, cushions and foam inserts harden within 6-12 months; a hygiene kit costs far less than a new muff.

Work at height — harnesses and lanyards

This group needs the tightest discipline. Under the work-equipment regulations, height-safety gear takes periodic inspection at least annually by competent persons, with records kept. Manufacturers typically declare a maximum life of up to ~10 years from manufacture for textile harnesses and lanyards (heavy use shortens it drastically). A harness that has arrested a fall is destroyed after that single event.

Safety footwear

On S1P/S3 footwear, sole wear, lost waterproofing and toe impacts set the limit: typically 6-12 months in heavy site use, 12-24 months in mixed office/warehouse duty. A toe cap that has taken a serious impact is considered spent.

High-visibility clothing

Reflective stripes dim with washing; manufacturers declare a maximum wash count (often 25-50). A faded, greyed vest no longer meets EN ISO 20471.

From calendar to stock plan: three steps

1. Keep issue records with dates — who received what, when; add manufacture dates for helmets and harnesses. A simple table suffices.
2. Extract consumption norms for consumable PPE (gloves, masks, plugs) from 2-3 months of data, per person per month.
3. Anchor lifed items to an annual renewal calendar — bulk renewal of helmets, harnesses and footwear at fixed anniversaries cuts prices and keeps the audit file tidy.
