UNE-EN 17353:2020+A1:2025. PROTECTIVE CLOTHING. ENHANCED VISIBILITY EQUIPMENT FOR MEDIUM RISK SITUATIONS. REQUIREMENTS AND TEST METHODS. Equivalence with EN 17353:2020 A1:2025.
This standard specifies visibility requirements for garments or devices that are capable of visibly signaling the wearer’s presence.
Enhanced visibility equipment is intended to provide visibility to the user in medium-risk situations, under any daylight conditions or under illumination from vehicle lights or reflectors in the dark.
Requirements include color and retroreflection, as well as the minimum area and location for protective materials.
This standard does not apply to situations with a risk of high visibility (see EN ISO 20471); visible head, hand and foot equipment; equipment with integrated active light (e.g. LEDs); low-risk visibility situations.
TYPES DEPENDING ON USE:
There are 3 types depending on the use:
Type A: Equipment for users to be seen in daylight conditions. These teams use only fluorescent materials as a component.
Type B: Equipment for users to be seen in dark conditions. These equipment use retroreflective materials as a component of improved visibility. This type has 3 levels depending on the area or location of the device on the torso and limbs:
Type B1: Includes only pendant retroreflector devices designed to be visible in motion.
Type B2: includes retroreflective devices or retroreflective material located on the extremities temporarily or permanently designed for visibility in motion. At a minimum, the retroreflective material must be positioned on the limbs as removable material or incorporated into the garment permanently.
Type B3: Includes retroreflective material on the torso and limbs designed to be visible in static and motion. A combination of removable and permanent materials cannot be used in this type.
Type AB: Equipment for users where the risk of not being seen may occur during the day, night or twilight. This equipment uses fluorescent materials and retroreflectors and their combinations as a component of improved visibility. There are two types in this category:
Type AB2: to recognize the user in motion in dark conditions with the requirements of type A and B2.
Type AB3: to recognize the user in static conditions in dark conditions with the requirements of type A and B3.

DESIGN
General requirements according to EN ISO 13688 in addition to those specific to this standard
Protective clothing should protect the torso, neck, arms up to the wrists, and legs up to the ankles during search and rescue activities other than fire.
Protective clothing must be made of materials that are resistant to accidental ignition fires. In addition, it must provide protection to the user against weather conditions, rough surfaces, as well as mechanical strength and visibility requirements.
Clothing may not restrict any movement to the wearer
If the protection is given by means of a 2-piece outer suit, the jacket must be superimposed on the pants at all times and in the face of any movement.
The pockets must be able to close completely. The flaps must be sewn or have the ability to close the pocket. The measurements of these flaps will be 20 mm wider than the opening (10 mm on each side) to prevent the flap from entering the pocket.
The zippers must have a protective flap on the outside of the garment. In the case of using buttons, their maximum distance will be 150 mm. In the case of using zippers, they must be able to be locked when they are completely closed.
The sleeves and bottoms of the pants must not have hems. They may have side openings which must have a means of closure and the opening and closure must be covered.
Protective clothing may not have sharp edges, roughness, or protrusions that could cause injury to the wearer.
The collar of the garment must remain upright when closed around the neck and must be able to open easily.
