Hi-Vis Clothing Standards Changes

The AS/NZS 4602.1.2011 Hi Vis clothing standards workwear is being updated in 2017.


I expect that a recommendation in the current 2011 Standard will be mandated in the 2017 Standard.
Current Standard AS/NZS 4602.1:2011, page 17, Appendix B, Recommended use of retro-reflective strips on sleeves and legs of garments (informative) includes:

Recent research has shown that where a high visibility garment has sleeves or legs, or both, significant visual benefits can be obtained by adopting an optimum bio-motion configuration of retro-reflective strips on the sleeves and legs. This entails placing the strips as shown in Figure B1, as follows:

  1. Sleeves – A 50mm wide hoop of material around each sleeve, just above the elbow and around each wrist.
  2. Legs – A 50mm wide hoop of material around each leg just above each knee and at each ankle.
This configuration enhances the long distance recognition of the wearer as a human figure when viewed by retro-reflected light.

You have probably seen workers with the extra bands of tape on their shirts, jackets and pants. Bio-motion taping has already happened overseas.

The benefits of Bio-motion have been well researched and documented by a collaboration at Queensland’s University of Technology: School of Optometry and Vision Science – Professor Joanne Wood, Minerals Industry Safety and Health Centre – Professor Robin Burgess-Limerick and Professor David Cliff. One of their conference papers can be found here: Qld Mining Safety Conference 2015 paper

Rail

Metro Trains Melbourne (Vic Rail) (partnership of John Holland, UGL and MTR) includes Bio-motion in its November 2014 clothing standards for contractors, stipulating that Bio-motion taping is a requirement for their rail track staff.
Extract from Metro Trains Safety and Environmental Requirements for Contractors working on MTM Premises, April 2013, Clause 6.8.5. High Visibility Safety Garments Policy, page 17.

… Where a high visibility garment has sleeves or legs or both (such as overalls), significant visual benefits can be obtained by adopting an optimum bio-motion configuration of retro-reflective strips on the sleeves and legs. This entails placing strips as follows:

  1. Sleeves – A 50mm wide hoop of material around each sleeve just above the elbow and around each wrist;
  2. Legs – A 50mm wide hoop of material around each leg just above each knee and at each ankle.
  3. NOTE: This requirement is in addition to positioning of the strips on garments in accordance with the Australian Standard AS4602.1:2011. Read more.

Roads

Queensland’s Transport and Main Roads


From 1 July 2016 QTC has mandated that Class R tape strips to create a “bio-motion” (or “biological motion”) effect must be applied to all traffic shirts.
Extract from Transport and Main Roads - Queensland Traffic Controller Clothing Standard July 2016, page 3.

7. Enhancements to garments for extra visibility and conspicuity ... Mandatory Requirement from 1 July 2016 From 1 July 2016 Class R tape strips to create a “bio-motion” (or “biological motion”) effect must be applied to all traffic controller shirts, weatherproof garments, and trousers worn by traffic controllers undertaking traffic control functions in periods of darkness.

Mining

Low light levels are a constant hazard in mines. Collisions between vehicles and workers accounted for 28% of the 112 fatalities in the mining industry in Australia during 1998–2008 *

NSW 2015 Coal Operators’ Conference Feb 2015


Translating road safety research on night-time visibility to the context of mining.
Extract from above paper:

By adding bio-motion markings to standard retro-reflective clothing can enhance the night time conspicuity of mining workers especially in low light. This has the potential to be an affordable and convenient way to provide a sizable safety benefit.

Extract from above paper:

Low illumination is a hazard in underground mines and for night time operations at surface mines. Biomotion clothing has the potential to be a low cost and practical way to provide safety benefits in the mining industry. Does not involve modifications to vehicles, drivers or infrastructure.
