A picker in stiff, heavy fabric is one symptom. A forklift driver who cannot see that picker in a shaded aisle is another. Both can result from the same buying mistake: one uniform for every role. The right warehouse workwear is chosen role by role. Base it on vehicle traffic, temperature, manual handling and the goods stored. Then check it against the standards that apply, mainly EN ISO 20471 for visibility and EN 342 or EN 14058 for cold or cool conditions, before you place a bulk order. Hi-vis supports visibility alongside adequate lighting, vehicle controls and separation of pedestrians from moving equipment.
This guide shows safety managers, procurement heads and operations managers how to do that in practical steps. It covers role matching, hi-vis classes, cold store layering, fit, climate, branding, standards and a pre-order checklist.
Key Takeaway
- Specify warehouse workwear by role and zone, not one uniform for everyone.
- Set hi-vis class from vehicle speed, lighting and background, using EN ISO 20471 or ANSI/ISEA 107.
- Cold and cool zones need suitable layers checked against EN 342 or EN 14058, with the tested clothing combination and exposure conditions reviewed.
- Stretch, breathability and a full size range decide whether workers wear garments correctly.
- Keep logos off reflective and fluorescent areas, and test branding against your wash process.
- Run a size survey and wear trial before a bulk order, and keep reorders identical.
- Ask for certificates and test documentation, not claims.
How Do You Match Warehouse Workwear to Each Role?
Start with a zone-by-zone hazard map, not a catalogue. Each area of a warehouse carries a different mix of risks, so each needs a different garment priority.
| Zone or role | Main hazard | Garment priority | Standard to check |
| Picking and packing (ambient) | Repetitive bending, reaching, heat | Stretch panels, breathable fabric, strong seams | Task-specific fit and durability requirements; EN ISO 13688 alongside a relevant protective-performance standard where PPE is required |
| Forklift and reach-truck aisles | Collision with moving equipment | Hi-vis with well-placed reflective strips | EN ISO 20471 |
| Loading docks and yards | Moving trucks, rain, low light | Risk-assessed hi-vis class plus a suitable weather layer | EN ISO 20471 |
| Cold store and freezer | Sustained low temperature | Layered insulated system, with hi-vis where vehicle risks require it | EN 342 for cold environments at or below −5°C; EN 14058 for cool environments above −5°C |
| Flammable atmospheres | Incendiary electrostatic discharge | Electrostatic dissipative garments within an earthed system | EN 1149-5 |
| Handling ESD-sensitive electronics | Electrostatic damage to products | ESD-control garments selected within the site’s ESD programme | IEC 61340-5-1 programme requirements |
| Supervisors and visitors | Walking through live traffic zones | Hi-vis overlay, easy identification | EN ISO 20471 |
Writing the requirement per role also prevents over-specification. A cold store coat issued to an ambient picker costs more and can increase heat stress, while a light vest issued to a freezer worker fails on protection.
Staff who move between zones, such as dock teams who enter chillers, need adjustable layers that provide protection for each exposure without overheating in warmer areas.

Discuss Your Requirements →Which Hi-Vis Class Does a Warehouse Need?
The required class must come from your risk assessment, considering vehicle speed, lighting, background clutter and sightlines. Class 2 may suit some forklift aisles, while Class 3 may be appropriate for higher-risk yards and docks. These are examples, not fixed warehouse requirements under EN ISO 20471. ACI Workwear’s high visibility clothing range includes vests, polos, jackets and coveralls for these roles.
| EN ISO 20471 class | Minimum fluorescent background | Minimum retroreflective material | Illustrative warehouse use, subject to risk assessment |
| Class 1 | 0.14 m² | 0.10 m² | Lower-risk areas where the site assessment permits this class |
| Class 2 | 0.50 m² | 0.13 m² | Some forklift aisles and loading bays |
| Class 3 | 0.80 m² | 0.20 m² | Higher-risk yards and docks with moving trucks |
The figures above describe the separate background and retroreflective material route. Classification also depends on material performance and garment design, not area alone.
Sites in the USA reference ANSI/ISEA 107, which has its own class system. Check the class against the standard your market recognises, and do not assume the two are interchangeable.
How Should Cold Storage and Freezer Staff Dress?
Use three layers, not one heavy coat. Start with a moisture-wicking base layer. Add an insulating mid-layer. Finish with a wind-resistant outer layer, with hi-vis where vehicle risks require it. Layers let workers adjust when they move between a chiller and an ambient dock.
Moisture matters as much as warmth. Sweat trapped against the skin cools quickly once a worker stops moving, so wicking and breathability are specification points, not extras.
EN 342 covers cold environments at or below −5°C; EN 14058 covers cool environments above −5°C. Check the insulation performance and tested clothing combination, including the specified base layers. Match protection to temperature, air movement, activity level and exposure duration. Select suitable gloves, footwear and separate headwear independently, as these are outside EN 342’s scope. ACI Workwear manufactures insulated coveralls, jackets and trousers within its cold protective and freezer clothing range, and covers cold storage operations as a dedicated industry.
What Fit and Fabric Features Reduce Fatigue on Long Shifts?
Fit decides whether workers keep a garment on, fastened and in good condition. Look for:
- Stretch panels or active cuts at the shoulders, back and knees for bending, reaching and lifting
- Breathable, moisture-managing fabric for hot ambient warehouses, a real concern in India and the Gulf
- Reinforced knees and seams where kneeling and pallet contact wear fabric down
- Pockets placed for scanners and pens, with no loose drawstrings or cords near moving equipment
- A full size range, including women’s cuts, confirmed through a per-person size survey
A hi-vis garment that rides up or hangs loose can hide its reflective areas, so fit is a visibility issue too. Check how it works with other PPE. Trouser hems should sit over safety footwear without catching. Sleeves should work with gloves. Harnesses and scanner holsters should not cover the hi-vis material. For ambient-zone roles, everyday uniforms and utility garments from general workwear are usually the base to build from.
How Does Climate Change the Specification?
Ambient warehouses in hot regions such as India and the Gulf need lighter, breathable garments with fewer layers. Sites in cooler markets such as the UK and Germany need weather layers at docks and yards.
Many operators run a seasonal kit. A summer base set is joined by an insulating or waterproof layer in winter. Ensure each seasonal outer garment, or manufacturer-approved garment combination, meets the required hi-vis class when worn. ACI Workwear’s logistics range includes singlets, polos, softshell jackets and winter parkas for this approach.
Plan the seasonal layers in the original order. Adding them later risks mismatched fabric and fluorescent colour between batches.
How Do You Choose Branding That Survives Washing?
Embroidery and heat transfer printing are the two common options. Durability depends on the embroidery thread or transfer system and the laundry process. Heat transfer suits finer logo detail. Ask for wash-tested branding suitable for the garment. ACI Workwear offers both.
Whichever method you choose, keep logos off retroreflective tape and fluorescent panels. Covering them can cut the exposed area below the minimum for the class, and the garment may then no longer meet that class.
Follow the care label for wash temperature. Aggressive washing can wear down reflective tape and fabric finish. Ask for wash testing against your own laundry process before you commit to a bulk order.
Specifying Hi-Vis and Cold Store Workwear?
Discuss garment options, sizing and wash-tested branding with ACI Workwear before finalising your warehouse team’s workwear specification.

These are general references, not performance claims for a specific ACI garment. Request test documentation for the exact product you plan to order. Confirm local requirements with your safety adviser.
How Do You Order Warehouse Workwear in Bulk Without Mistakes?
Treat the order as a project, not a purchase. Run a size survey and approve samples through a wear trial. Then order in size-curve proportions, with spares for new starters. Keep the specification identical on reorders so fluorescent colour and fit stay consistent across batches.
Ask any supplier for evidence rather than relying on claims:
- Certificates and test reports for the exact garment, not a similar product
- Sample garments for a wear trial across roles and shifts
- Confirmation that fluorescent colour and reflective tape stay consistent across batches
- Packing, documentation and delivery expectations for export orders

FAQ
1. Does every warehouse need hi-vis clothing?
Not always, as it depends on your risk assessment. Any area with forklifts or moving vehicles usually needs it.
2. Which hi-vis class suits forklift areas?
Class 2 may suit some forklift areas, while higher-risk locations may require Class 3. EN ISO 20471 does not assign a fixed class to warehouse roles; your risk assessment decides.
3. What should cold store workers wear?
A layered system matched to the temperature, activity and exposure duration. Check EN 342 for cold conditions or EN 14058 for cool conditions, using the tested clothing combination.
4. Does warehouse workwear need to be flame resistant?
Not for every role. Select suitable thermal protection where heat or flame hazards exist. Electric-arc exposure requires arc-rated protection matched to the assessed incident energy.
5. Can company logos affect hi-vis compliance?
Yes. A logo that covers fluorescent or retroreflective areas can reduce the material below the class minimum.
6. How often should warehouse workwear be replaced?
Replace it when damage, persistent soiling, faded fluorescent fabric or degraded reflective tape compromises protection. Follow manufacturer inspection and cleaning limits, including any declared maximum wash cycles.
7. What order sizes does ACI Workwear handle?
Its enquiry form offers bands from 10 to 50 pieces up to above 500 pieces. Confirm exact terms in a quote.
