Night (N) Only garments are developed to be worn during the night time only as the retroreflective taping offers visibility from vehicle headlights.
The design of garments for this Standard are based primarily on the needs of workers in situations where vehicles may be approaching them at speed, in time for any necessary safety action to be taken, or any other industrial situation of similar risk levels where workers need to be seen at distance, against a complex visual background, in conditions of poor visibility or where they may appear suddenly in the path of moving plant equipment. Garments designed to AS/NZS 4602.1:2011 must have at least 0.2m2 of high visibility fabric (AS/NZS 1906.4:2010) on the front and on the back to meet the Day and/ or Day/ Night Standard. Garments designed to AS/NZS 4602.1:2011 for Day/ Night or Night Standard must have a compliant retroreflective taping configuration in, what is commonly known as, a ‘H’ Pattern or ‘Hoop’ Pattern. High visibility material must encircle the upper body, underarm ventilation panels must be no more than 10cm wide x 10cm high.
