THE CLASS on the label describes the garment as certified when new. It is
important for sites to be aware that wear and washing can take it below that
class while the label stays the same. For logistics sites issuing hi vis
across several shifts, tracking that decline is a substantial workload.
Rental moves much of that work to a provider, while the legal duty stays
with the employer.

The three classes of hi vis clothing under EN ISO 20471

EN ISO 20471:2013+A1:2016 classifies garments by the visible area of two
materials. Fluorescent background material provides daytime conspicuity,
while retroreflective tape returns light from headlights towards its source.
The minimum areas for each class are set out below.

Class	Fluorescent background material (minimum)	Retroreflective material (minimum)
Class 3	0.80 m²	0.20 m²
Class 2	0.50 m²	0.13 m²
Class 1	0.14 m²	0.10 m²

Certification testing uses a sample in the smallest available size, so
larger sizes carry at least the stated area. Class depends on measured area,
so garment type alone never confirms it. Two vests that look identical can
hold different classes.

Class 1

Class 1 typically covers hi vis trousers worn alone, or tops with limited
fluorescent area. Its 0.14 m² background minimum is less than a fifth of the
Class 3 requirement. In logistics, it can suit pick areas fully segregated
from vehicle movement, where the risk assessment supports it.

Class 2

Many vests and tabards are certified to Class 2, though only the label
confirms it. On floors where pedestrians and forklifts share space, it is a
common baseline. Whether it is sufficient depends on lighting, traffic
density and vehicle speed.

Class 3

A Class 3 garment must cover the torso and have banded sleeves, banded
full-length trouser legs, or both. Typical examples are long-sleeved
jackets, coveralls and certified jacket-and-trouser ensembles. In logistics,
it suits yard marshallers, banksmen at loading bays and anyone on foot in
the yard after dark.

Which class does each logistics role need?

No regulation assigns a hi vis class to a warehouse job title. The class
follows the site’s risk assessment under the PPE at Work Regulations.
HSE guidance
sets the main factors: lighting, weather and the wearer’s exposure to moving
vehicles. As a working rule, the darker the conditions, the more hi vis
clothing is needed.

Area	What to assess	Illustrative starting point
Segregated pick and pack areas	Physical barriers, no vehicle access	Class 1 or 2
Forklift aisles and shared floors	Traffic density, blind ends, racking height	Class 2
Loading bays and dock doors	Reversing HGVs, sharp changes in light level	Class 2 or 3
External yards and marshalling	Vehicle speed, darkness, weather	Class 3
Night shifts and dark winter shifts	Reliance on headlights and site lighting	Class 3 for yard roles

 

These examples apply HSE’s principles, but each site’s risk assessment sets
the actual class. Lighting deserves particular care, because fluorescent
fabric depends on daylight. Retroreflective tape only works when a light
source sits near the viewer’s eye, such as headlights. A 6am yard shift in
December may therefore need a higher class than the same shift in June.

Why keeping hi vis in class is hard to manage in-house

HSE guidance says employers must keep hi vis clean, in good working order
and checked before issue for as long as a garment is in use. For sites, this
requires tracking several kinds of decline which can take garments below
their certified class. 

Wash cycle limits

The care label states the maximum number of cleaning cycles the garment was
tested to. If none is stated, the materials were tested after at least five
cycles. Manufacturers note that this count is not the only factor in garment
life. Tracking it is difficult where garments circulate in a shared pool
across shifts. Without a wash log or garment tagging, a site can only
estimate it.

Fading, soiling and tape damage

Fluorescent fabric degrades under UV exposure and repeated laundering. EN
ISO 20471 sets colour (chromaticity) and brightness (luminance) requirements
that the fabric must still meet after washing. A faded vest can look yellow
to the eye while falling outside those values. Retroreflective tape wears
against pallets, racking and vehicle steps, and high drying temperatures can
crack it. On a Class 2 garment near the 0.13 m² minimum, even minor tape
loss can drop it below class.

Ensembles, logos and sizing

A certified ensemble loses its combined class when one half is missing or
swapped for another range. A logo printed over fluorescent fabric removes
that area from the certified total, affecting small sizes most. Unauthorised
modifications can void the garment’s conformity with EN ISO 20471.
Protection also depends on fit, since a garment must be the right size and
properly closed. Peak-season starters add sizing and issue volume to manage
at short notice.

How rental reduces the hi vis workload, and what remains the site’s
responsibility

The PPE at Work Regulations place the hi vis duty on the employer. Since 6
April 2022, that duty also covers limb (b) workers, who generally do casual
or irregular work. The amendment applies in England, Scotland and Wales.
While renting garments does not remove this responsibility from the
employer, it does change who carries out most of the maintenance and who
holds the paperwork that records it.

The table maps HSE’s five employer duties against what a rental service can
cover. The split varies by contract, so each line should be confirmed in
writing with the provider. Anything the contract does not cover stays with
the site by default.

 

HSE employer duty	What a rental service can cover	What stays with the site
Provide hi vis free of charge to workers at risk	Supplies garments in the specified size and class	Specifying the class from the risk assessment, never charging workers
Keep it clean, in good working order and checked before issue	Laundering to the care label, inspection each cycle, withdrawal and replacement	Acting on damage reports between collections
Provide storage when not in use	Collection and delivery points, where agreed	Storage on site
Give information, instruction and training	Garment care and wear information, where agreed	Training on site risks and correct use
Supervise correct use	Not covered	Supervision on the floor

The second duty is where rental changes the most. In-house, every wash,
inspection and replacement relies on site staff and their records. Under
rental, garments are typically laundered, inspected and replaced as part of
each collection cycle. HSE still asks employees to report damage, which
covers faults that appear between collections.

What to ask a hi vis workwear rental provider

The compliance value of rental depends on what the contract commits the
provider to. Logistics buyers should check how a provider handles each of
the points below. Each one maps to a requirement in EN ISO 20471,
manufacturer user information or HSE guidance.

• Current certification: every garment certified to EN
  ISO 20471, with no stock marked only to the withdrawn EN 471.
• Class by role: the class specified for each role
  recorded in the contract, so replacements arrive at the same level.
• Wash count tracking: how each garment’s cleaning cycles
  are counted against its stated maximum, and when it is retired.
• Laundering method: a process that matches each
  garment’s care label and the cleaning method it was certified for.
• Inspection criteria: what is checked at each cycle,
  covering label, fabric colour, staining, tape, seams, fastenings and
  fit.
• Sizing for starters: correctly sized garments for new
  and peak-season staff, issued at short notice.
• Audit records: inspection, withdrawal and wash count
  records available to the site on request.

Sites using hi vis workwear rental
should hold these records alongside their own risk assessment. Some
companies, like Lindström UK, offer their own portals where you can track
workwear’s life cycle to ensure compliance.  Together, they show which class
each role needs and that each garment still meets it. An auditor will look
for both halves of that evidence, from the site and from the provider.
Without the provider’s records, the site cannot show the maintenance duty is
being met.
