Safety Vest Classes Explained: Class 1, 2 & 3 Differences You Need to Know
By Aquaholic Gifts Malaysia | Published 27 March 2026 | 8 min read
If you are ordering safety vests for your workforce in Malaysia, you have probably seen the terms “Class 1,” “Class 2,” and “Class 3” on product listings and data sheets. These classes are not marketing labels — they are internationally recognised visibility grades defined by EN ISO 20471, the standard that governs high-visibility clothing worldwide.
Choosing the wrong class can leave your workers under-protected or your company non-compliant with DOSH regulations in Malaysia. This guide breaks down what each class means, who needs it, and how to pick the right one when you customize safety vests for your team.
What Determines a Safety Vest’s Class?
The class is determined by two measurable factors: the total area of fluorescent (hi-vis) background material and the total area of retroreflective strips on the garment. More material means a higher class and greater visibility.
The fluorescent fabric (the bright yellow, orange, or red body of the vest) makes the wearer visible during daylight. The reflective strips bounce light from vehicle headlights back toward the source, making the wearer visible at night. Both work together — and the minimum amount of each is what separates one class from another.
For a comprehensive look at the standard itself, see our full EN ISO 20471 guide for Malaysian businesses.
Class 1 vs Class 2 vs Class 3: Side-by-Side Comparison
| Specification | Class 1 | Class 2 | Class 3 |
|---|---|---|---|
| Min. fluorescent material | 0.14 m² | 0.50 m² | 0.80 m² |
| Min. reflective material | 0.10 m² | 0.13 m² | 0.20 m² |
| Visibility level | Basic | Standard | Maximum |
| Traffic speed environment | ≤ 30 km/h | 30–60 km/h | > 60 km/h |
| Typical garment type | Sash or belt | Vest (sleeveless) | Jacket or coverall with sleeves |
Class 1 Safety Vests — Basic Visibility
Class 1 provides the minimum level of visibility and is suitable only for environments where traffic speed does not exceed 30 km/h and the wearer is well-separated from vehicle paths. Think of controlled areas like private car parks, low-traffic warehouse aisles, or supervised indoor facilities.
Because Class 1 only requires 0.14 m² of fluorescent fabric, the garments are often simple sashes, belts, or narrow vests rather than full-coverage torso garments. They are not considered adequate for construction sites, public roads, or any setting where vehicles travel at moderate-to-high speeds.
Who uses Class 1: Car park attendants, visitor pass wearers, retail stock-room staff, and pedestrians in low-risk zones.
Class 2 Safety Vests — The Malaysian Standard
Class 2 is the workhorse of workplace safety in Malaysia. With 0.50 m² of fluorescent material and at least two horizontal reflective bands around the torso, a Class 2 vest provides enough coverage to keep workers visible in environments where traffic moves between 30 and 60 km/h.
This is the class most commonly required on construction sites, in logistics yards, at loading docks, and for general warehouse operations in Malaysia. When companies contact us as a safety vest Malaysia supplier, approximately 80 percent of orders are for Class 2 garments.
Class 2 vests are typically sleeveless, which makes them ideal for layering over uniforms or T-shirts — and they provide the most practical canvas for safety vest printing with your company logo on the front chest and back panels.
Who uses Class 2: Construction workers, warehouse staff, forklift zones, delivery drivers, crossing guards, event marshals, and most general industrial workers.
Class 3 Safety Vests — Maximum Visibility
Class 3 provides the highest level of visibility defined by EN ISO 20471. It requires 0.80 m² of fluorescent material and 0.20 m² of reflective material — meaning the garment must include sleeves with reflective strips, not just a sleeveless vest.
This class is mandatory in high-risk environments: highway shoulders, active road construction zones, night-time work, railway lines, airport tarmacs, and any location where vehicles travel above 60 km/h. In these settings, the wearer’s outline must be visible from all directions, including side-on — something only possible with sleeved garments.
If your team works alongside high-speed traffic, selecting a customized safety vest at Class 3 level is not optional — it is a safety imperative. Consult our guide on DOSH safety vest requirements in Malaysia for the legal perspective.
Who uses Class 3: Highway maintenance crews, road construction workers, railway workers, airport ground staff, emergency responders, and oil & gas site workers near active traffic.
Which Class Does Your Team Need?
The right class depends on two main factors: the speed of nearby traffic and the ambient lighting conditions. Use this quick decision framework:
| Your Work Environment | Recommended Class |
|---|---|
| Private car park, indoor warehouse with no forklifts | Class 1 |
| Construction site, warehouse with forklifts, loading dock | Class 2 |
| Event marshalling, delivery yards, factory floor | Class 2 |
| Roadside or highway work, any night-time outdoor work | Class 3 |
| Railway, airport tarmac, emergency response zones | Class 3 |
Not sure where your workplace fits? Our guide on how to choose the right safety vest for your workplace walks you through every variable — from material type to colour coding.
Can You Print Logos on Classified Safety Vests?
Yes — with one important rule. Your logo must not cover or reduce the minimum fluorescent and reflective areas required by the vest’s class. In practice, this means logos are placed in designated zones: the front chest panel, the upper back panel, or the shoulder area between the reflective strips.
At Aquaholic, when clients order a safety vest with company logo, our design team prepares a mockup that shows exactly where the branding will sit relative to the reflective strips. This ensures compliance is maintained while giving you prominent brand visibility. We have supplied custom-printed Class 2 vests to construction firms, logistics companies, and event organisers across Malaysia.
Frequently Asked Questions
What is the most common safety vest class used in Malaysia?
Class 2 is the most widely used class across Malaysian workplaces. It meets the requirements for construction sites, warehouses, logistics yards, and most general industrial environments where workers are near moving vehicles or machinery.
Can I print my company logo on Class 2 and Class 3 safety vests?
Yes, as long as the printing does not reduce the minimum fluorescent and reflective material. Logos are typically placed on the chest, back, or shoulder areas between the reflective strips.
What happens if my workers wear the wrong class of safety vest?
Your workers may not be visible enough for the risk level. In Malaysia, DOSH can issue fines or stop-work orders for non-compliant PPE. Inadequate visibility is also a leading factor in workplace accidents involving vehicles and heavy machinery.
Is there a Class 4 safety vest?
No. EN ISO 20471 only defines three classes. Class 3 is the highest level of hi-vis protection available under the standard.
