Safety High-Visibility Vest first aid only P-91911 00, yellow, one size, EN ISO 20471 certified, reflective

The Safety High-Visibility Vest by first aid only (model P-91911 00) is a yellow, one-size garment certified to EN ISO 20471 for high-visibility performance. Designed with reflective strips, this vest increases wearer visibility in low light and roadside conditions. It is lightweight, easy to don over clothing and intended for use where clear visual identification and basic personal safety are required.

Advantages

This high-visibility vest meets the EN ISO 20471 standard, providing verified reflective performance for improved detection by drivers and co-workers. The one-size design accommodates a wide range of body types and layers, making it practical for emergency scenes, roadside assistance, or short-term tasks. Its bright yellow color and strategically placed reflective bands enhance visibility from multiple angles without adding significant bulk.

Suitable for

• Roadside emergencies and vehicle breakdown assistance
• Construction sites and maintenance work near traffic
• Event staff, traffic marshals and safety supervisors
• Warehouse tasks and logistics where enhanced visibility is needed
• Volunteer response teams and first responders requiring quick identification

When it may not be suitable

While the vest improves visibility, it does not provide thermal insulation, impact protection, or flame resistance; it is not a substitute for specialized PPE required in hazardous environments. It is intended for short-term or supplemental use over everyday clothing rather than as the sole protective garment in industrial or high-risk operations.

Key specifications

• Color: Yellow for daytime visibility
• Size: One size designed to fit most adults and to be worn over clothing
• Certification: EN ISO 20471 compliant for high-visibility garments
• Reflective features: Multiple reflective strips for enhanced low-light detection
• Material and fit: Lightweight construction for ease of use and portability

How to use

Put the vest on over your outer clothing and secure any fastenings so it fits comfortably without restricting movement. Ensure the reflective strips are visible from the front and rear and not obstructed by items such as backpacks or tool belts. Use the vest whenever working near traffic, during roadside assistance, or in any situation where increased visibility would reduce the risk of accidents. After use, fold or roll the vest for compact storage and inspect reflective areas regularly for wear or damage.

What to consider before purchase

• Confirm EN ISO 20471 certification if regulatory compliance for high-visibility clothing is required
• Consider whether additional protective features such as flame resistance or impact protection are needed for your tasks
• Check that a one-size design is suitable for users who may need a more tailored fit or have very small or large body sizes
• Plan for how the vest will be stored and maintained to preserve reflective performance

Usage recommendations

Use the vest as a visible layer over clothes in low-light, roadside, or high-traffic situations. Combine with other appropriate safety equipment when working in environments that require protection beyond visibility, and replace the vest if reflective elements become worn or damaged.
