frequently asked questions
Hi-vis trousers are usually part of a full-body high-visibility system and can contribute to achieving EN ISO 20471 Class 2 or Class 3 compliance—depending on how much fluorescent and reflective material they contain. On their own, trousers may be Class 1 or 2, but to meet Class 3, they are typically worn in combination with a hi-vis jacket or coverall. Always check the garment’s label and certification for specific classification.
Hi-vis trousers are commonly used in sectors where visibility is essential for safety, including:
- Rail and infrastructure (often requiring RIS-3279-TOM compliance)
- Utilities and energy
- Construction and highways
- Transport and logistics
- Waste management and emergency response
PPE requirements should always be based on your organisation’s formal risk assessment.
If your team works in low-light conditions, alongside moving vehicles or machinery, or in environments where visibility is a safety-critical factor, hi-vis trousers may be appropriate. A risk assessment will help determine the right level of visibility protection, and whether trousers should be worn alongside other hi-vis garments.
The main standard is:
- EN ISO 20471 – Specifies the minimum area of fluorescent and retroreflective material required for visibility.
Where applicable, the following may also be relevant:
- RIS-3279-TOM – For rail industry compliance in the UK.
Garments must meet the appropriate class and construction requirements to be certified under these standards.
Replacement depends on usage, care, and wear. Over time, colour fading, tape damage, or general wear can reduce visibility performance. Hi-vis trousers should be regularly inspected, and any item that no longer meets visibility or safety requirements should be withdrawn from use in line with your internal PPE policy.
Yes. At alsico, we offer custom-made hi-vis trousers that can be adapted for specific operational needs. This might include alternative leg lengths, added pockets, tool loops, or integration with additional protective standards such as flame resistance or anti-static properties—while still meeting visibility compliance where required.
