B3.2 Logos

 
   

 

Garments must not display any lettering, symbols or logos on any compliant high visibility material except within an area located on the upper front left side of the garment.

The maximum area permitted is 7500mm2 (eg 100mm x 75mm).

Garment designs that include a clear plastic pocket where a business card   or similar identification may be displayed must locate this pocket within the above  described  maximum 7500mm2.

Where required for related safety reasons a fabrics technical recognition

I.D. may be added in an area not exceeding 30mm x 30mm (900mm2) to the upper front right side of a garment.

A manufacturers label to a maximum size of 50mm x 20mm may be sewn or printed on non-compliant material on the lower sleeve or leg.

 
   


Note: The STMS garment is limited to the STMS logo located on the upper front left side of the garment and as specified on the back of the garment and the technical recognition I.D. as appropriate. Other logos or labels may not be added.

 

B3.3 Garment compliance

 
   

 

Garment compliance is based on the Australian and New Zealand Standard AS/NZS 4602.1:2011 High visibility safety garments Part 1: Garments for high risk applications and the additional subsections that follow herein. Because all background high visibility material must comply with the wet test, as specified in subsection B3.1.1 Colour, new compliance letters ‘TTMC-W’of a practicable size must be included on the garment label to confirm that the garment meets the requirements and is compliant with section B3.

Note: Refer also to subsection B3.4.7 Exemption for extra small size garments.

All retro-reflective material applied to garments, including extra small size garments complying with subsection B3.4 Garment design must be in strips no less than 50mm wide. Hoops must completely encircle the torso with no breaks except for the permitted front opening. Braces or the rear cross configuration must meet at the top of the shoulder and at the hoops.

Garment compliance must be achieved for a recognised small garment designed for a size 92-95cm body chest measurement. This design must remain consistent throughout the garment size range, grading increasing or decreasing proportionately with the design integrity of the compliant small size.

 
   


Garment designs must not be altered without the direct authority of the NZTA. The NZTA may request a garment manufacturer to present a compliance certificate to confirm garment design compliance. In such instances the garment manufacturer will be required to forward material compliance certificates covering colour, luminance and retro-reflectivity with the garment to an NZTA approved industrial testing laboratory.

 

 

 

B3.4 Garment design

 

The Australian and New Zealand standard AS/NZS 4602.1:2011 has now been amended by Amendment 1:2016. This amendment has created a variation between CoPTTM and AS/NZS 4602.1. Only one measurement is involved and the implications of this amendment remain under discussion. We are hopeful of having a resolution by 1 May 2017. A CoPTTM Technical Note will be published in the CoPTTM section of the NZ Transport Agency website.

 

B3.4.1 Sleeveless vest

B3.4.1.1 Sleeveless vest  requirements

The sleeveless vest design, based on the Australian and New Zealand standard AS/NZS 4602.1:2011 must include the following additional requirements:

  • when calculating the area of high visibility background material as specified in clause 6.4.2 in AS/NZS 4602.1:2011 the measurement rectangle shown in clause 6.4.5 and Appendix A may be extended below waist level to the bottom of the garment providing such extension for the small  size  does not exceed 680±5mm at the front
  • the design must include a shirt tail back that is 150±5mm longer than the front
  • the garment’s shirt tail may be split, providing an overlap of material ensures that continuity of background material is maintained. It is recommended that a hook and loop product secures the split. This feature may be included if there is a danger that the garment could snag when the wearer alights from any construction equipment. However, good practice dictates that when alighting from any construction equipment the operator faces the vehicle
  • background high visibility material must encircle the torso from the top without the inclusion of any other colour except for:
  1. Specified retro-reflective material
  2. Permitted front opening and
  3. Permitted logo and technical ID area
  • the minimum qualifying area measurement of background high visibility material for the recognised small size vest not covered by retro- reflective material or printing must be:
  1. Front of garment 0.21m2
  2. Rear  of garment including the 150mm shirt tail 0.27m2
  • a permitted front opening to accommodate a zip fastener or similar closing device may be no wider than 25mm. Zip colour may be black but  a colour matching the garment colour is preferred. Any buttons, domes or similar closure devices on any compliant high visibility must match   the colour of the garment (matching colour need not be compliant)
    • compliant retro-reflective material must be positioned to comply with the pattern in Figure 1

 

 

 

 

  • the retro-reflective elements must form a recognised belt and braces pattern with an additional horizontal strip on the shirt tail located 50±5mm above the bottom hem. The braces join the belt at the front, passing over the shoulder to the belt at the back
  • each brace must be spaced a minimum of 150mm apart at the belt, front and back as shown in Figure 1
  • An optional cross configuration permitted for the back only must meet the front braces at the shoulder and the belt at the back vertically below the shoulder position to comply with the pattern in Figure 1
  • The optional retroreflective cross configuration on the back of a garment is not permitted for STMS  garments.

Note: Refer to subsection B3.4.7 Exemption for extra small size garments that follows.

High visibility garments must always be worn correctly fastened.

B3.4.1.2 Application of cross configuration on back of high visibility garment

To date NZTA has seen little evidence that supports any improvements in safety by using the cross configuration on the back of high visibility garments rather than the belt and braces configuration.

Despite this lack of evidence NZTA is allowing the use of an optional cross configuration on the back of high visibility garments.

The optional retroreflective cross configuration on the back of a garment is not permitted for STMS garments.

Contractors will be able to use this optional cross configuration for their staff but will not be able to require subcontractors or any visitors to site to have the cross configuration rather than the belt and braces configuration on the back of their high visibility garments.

The effective date for the introduction of the cross configuration will be 1 October 2016.

B3.4.2 STMS and

MTC garments

Two special purpose garments differ from the standard compliant orange coloured high visibility garment range specified in section B3.4 Garment design.

Although these garment designs must comply with the standard compliant orange garment design the background material colour must become a compliant fluorescent yellow where specified.

Both garments identify the specialised responsibility of the wearer.

B3.4.2.1 STMS sleeveless vest

The STMS sleeveless vest enables the person responsible for TTM at a worksite to be readily identified.

The STMS vest (Figure 2A) has the same specifications as the sleeveless vest specified in subsection B3.4.1 Sleeveless vest except for the following subsections:

  • the background material colour must be fluorescent yellow, commonly known as lime yellow, as specified in clause 2.3, Table 2.1 and Table 2.2 of   AS/NZS 1906.4:2010.

Note: Class NF non fluorescent yellow high visibility background material may be used for an STMS vest when appropriate. (Refer to subsection B3.1.1 Colour)

  • a retro-reflective fluorescent orange red panel measuring 150mm x 150mm (±10mm) must be placed on the upper left front of the garment. This panel may cover some of the retro-reflective element at the front and replaces the permitted logo area. Refer to subsection B3.2  Logos
  • a retro-reflective fluorescent orange red panel measuring 300mm x 150mm (±10mm) must be placed on the upper back of the garment, between the retro-reflective braces. This panel may cover some of the retro-reflective elements at the back.

The optional retroreflective cross configuration on the back of a garment is not permitted for STMS garments.

The STMS sleeveless vest may be substituted by a long sleeved coat, overalls or miscellaneous garment design but must maintain the STMS badging and colour specification.

An STMS on all Level  2  and Level  3  roads must wear this garment.

This garment must also be worn by an STMS on Level LV and Level 1 roads where there are three or more personnel on the site. Where there are less than three personnel on the site the STMS may wear a standard orange red garment.

 

 

 

 

 

 

B3.4.2.2 Optional MTC Garment Sleeve

The optional addition of fluorescent yellow material for the sleeve of the MTC STOP/GO operator is designed to provide additional visibility for this function when thought appropriate for the location.

The only item of difference to the standard compliant orange garment is the sleeve colour and the addition of retroreflective hoops around the arms to enhance this function when required at night. No additional changes may be included.

The sleeve colour must comply with the colour specified for the STMS Sleeveless vest (refer subsection B3.4.2.1 STMS sleeveless vest). Two compliant retro-reflective hoops must be positioned to comply with the pattern in Figure 2B. Each sleeve must have two retroreflective hoops, one positioned above the elbow and one below the elbow and close to the wrist.

B3.4.3 Long-sleeve coat

A worker, supervisor or visitor may, in some instances, find it necessary or practicable to wear a long-sleeve outer coat. If this garment is to act as a high visibility garment it must comply with the general requirements for the high visibility sleeveless vest specified in subsection B3.4.1 Sleeveless vest  as well as the following additional  subsections:

  • the 150mm shirt tail design is to be deleted
  • the minimum qualifying area measurement of background high visibility material for the recognised small size coat not covered by retro- reflective material or printing must be measured in the same way as the sleeveless vest specified in subsection B3.4.1 Sleeveless vest except that the measurement rectangle must extend a minimum of 830mm at the front and back. Sleeves are not included in this area
  • the area of background material must be determined as follows:
  1. Front of garment 0.3m2
  2. Rear  of garment 0.3m2
  • the sleeves of the garment must be the same fluorescent colour as the torso to a point between the elbow and the wrist
  • compliant retro-reflective material must be positioned to comply with the pattern in Figure 3

 

 

 

 

  • An optional cross configuration permitted for the back only must meet the front braces at the shoulder and the belt at the back vertically below the shoulder position to comply with the pattern in Figure 3
  • a hoop of complying retro-reflective material must be located between the wrist and the elbow on each sleeve. This may be at the point of a colour change if the lower arm design includes a different colour.

Note: An optional hoop of compliant retro-reflective material may be located on the sleeves above the elbow

  • a strip of complying retro-reflective material must be located on the back of the garment from side seam to side seam positioned 50±5mm from  the bottom hem.

Note:  An option permits this strip to completely encircle the garment.

  • Non-compliant colours may not be located within the qualifying torso area as trim or pocket flaps. Collar material may be a non-compliant colour but any such material that covers qualifying high visibility material in its normal worn position must be deducted from the qualifying torso area
    • to lessen the effect of wear discolouration, non qualifying material colours may be used:
  1. As noted above for the garment collar
  2. Below the retro-reflective hoop at the midpoint between elbow and wrist.

 

 

 

 

 

 

B3.4.4 Overall garment


Where required, a worker may find it necessary or practicable to wear a one piece overall type garment. If this garment is to act as a high visibility garment it must comply with the general requirements for the high visibility sleeveless vest specified in subsection B3.4.1 Sleeveless vest as well as the following additional subsections:

  • the 150mm shirt tail design is to be deleted
  • the minimum qualifying area measurement of background high visibility material for the recognised small size garment not covered by retro- reflective material or printing must be measured in the same way as the sleeveless vest specified in subsection B3.4.1 Sleeveless vest except that the measurement rectangle must be extended to a point on the leg above the knee.

  • An optional cross configuration permitted for the back only must meet the front braces at the shoulder and the belt at the back vertically below the shoulder position to comply with the pattern in Figure 4
  • a hoop of complying retro-reflective material must be located between the wrist and the elbow on each sleeve and above the knee on each leg  to enhance long distance recognition of the wearer as outlined in Appendix B of AS/NZS 4602.1:2011. These hoops of retro-reflective may be located at a change of colour if a change is  designed.

Note: An optional hoop of compliant retro-reflective material may be located on the sleeves above the elbow and on the legs below the knee

  • non-compliant colours may not be located within the qualifying area as trim or pocket flaps. Collar material may be a non-compliant colour but any such material that covers qualifying high visibility material in its normal worn position must be deducted from the qualifying torso area
  • to lessen the effect of wear discolouration non qualifying material colours may be used:
  1. As noted above for the garment collar
  2. Below the retro-reflective hoop between elbow and wrist on the arm and below the upper hoop on the leg of the overall.

B3.4.5

Miscellaneous garments

Garment types alternative to the primary garment specified in subsection B3.4.1 Sleeveless vest such as Polo shirts, woven shirts, ‘T’ Shirts and polar fleece garments may be granted compliance providing the following  is met:

  • the minimum qualifying area measurement of background high visibility material for the recognised small size garment not covered by retro- reflective material or printing must be:
  1. Front of garment 0.21m2
  2. Rear of garment including the 150mm shirt tail 0.27m2 Note: Sleeves are not included in this area

  • the configuration of compliant retro-reflective material complies with  the configuration specified in subsection B3.4.1 Sleeveless vest including a strip on the shirt tail at the back
  • An optional cross configuration permitted for the back only must meet the front braces at the shoulder and the belt at the back vertically below the shoulder position to comply with the pattern in Figure 5
  • where the design includes short sleeves they must remain the same high visibility colour as the garment. If long sleeves they must remain the same high visibility colour to a point no less than midway between the elbow and wrist
  • if the garment has long sleeves, placement of a compliant retro- reflective hoop on the arm between the elbow and the wrist is required as is specified in subsections B3.4.3 Long-sleeve coat and B3.4.4 Overall garment and Figures 3 and 4.
  1. Material area in the sleeves must not be used to achieve area compliance for high visibility background  colour
  2. An optional hoop of compliant retro-reflective material may be located on the sleeves above the elbow

 

 

 

 

 

  • the area of compliant high visibility background material is measured from material that will be visible when the garment is worn in its normal manner.

Note: Wearers should be aware that such garments will not comply when tucked into trouser type garments

  • non-compliant colours may not be located within the qualifying torso  area as trim or pocket flaps. Collar material may be a non-compliant colour but any such material that covers qualifying high visibility material in its normal worn position must be deducted from the qualifying torso area.

B3.4.6 Fire Service garments

The objective of this subsection is to recognise special requirements for firefighters while working on or near the road at a fire or other emergency where the wearing of safety garments must first meet the unique requirements of either AS/NZS 4967 Garments for structural firefighting or AS/NZS 4824 Garments for Wildland firefighting.

Whilst carrying out routine maintenance operations such as hydrant testing for a local council high visibility garments must be TTMC-W compliant.

Essential Fire Service related garment recognition patches or printing may exceed subsection B3.2 Logos specifications provided size and number are limited and do not risk overall visibility safety.

Background high visibility material may be yellow green Class F or Class NF conforming to the requirements of clause 2.3, Table 2.1 and Table 2.2 or Table 2.3 in AS/NZ1906.4:2010. Such material must comply in a dry and wet condition as noted in subsection B3.1.1 Colour.

Where practicable a high visibility vest complying with subsection B3.4.1 Sleeveless vest may be worn providing this is appropriate for the situation at hand and the wearing of such a garment does not become hazardous for the wearer.

Fire Service personnel attending such emergencies within the roading network are exempted from wearing TTMC-W compliant high visibility vests in the following circumstances:

  • the fire service personnel are at the immediate fire or potential fire location
  • high visibility is achieved by a garment that in addition to compliance with AS/NZS 4967 or AS/NZS 4824 Standards also complies with AS/NZS 4602.2 High visibility safety garments Part 2: Garments for fire service personnel
  • high visibility is achieved by a garment that in addition to compliance  with  AS/NZS  4967  or  AS/NZS  4824  Standards  also  complies  with AS/NZS 4602.1 High visibility safety garments Part 1: Garments for high risk applications.

Fire service personnel carrying out traffic control support of an emergency are reminded of the need to be visible.

 

 

 

 

B3.4.7 Exemption for extra small size garments

Dispensation for an extra small fitting garment will be permitted provided it meets the requirements of the compliant recognised small size garment with the following exceptions:

  • if on an extra small sized garment designed to fit a chest size of less than 92cm where it is not possible to accommodate the minimum specified area of high visibility background material, the garment must be deemed to comply provided the garment design grading decreases proportionately without affecting the design integrity of the compliant small size of the garment range
  • such extra small size garment must maintain the same configuration of compliant retro-reflective material as specified for the recognised small size of the design.

In addition, the following subsections also apply to extra small fitting garments:

  • a card, which is clearly visible to a purchaser, must be included in the garment’s packaging stating that this extra small fitting garment has reduced visibility in both day and night conditions and that, because of this limitation, those wearing the garment would normally avoid working in areas of high risk
  • an additional separate sewn in label clearly visible to the wearer (refer to Figure 6) must alert the wearer to the reduced visibility of extra small fitting garments.

 

 

 

Figure 6: Extra small garment label

 

 

Management must ensure that any employee wearing an extra small fitting garment is aware of the potential hazards resulting from its lower  visibility.

 

 

 

B3.5 Garment durability

 
   

 

Due care and maintenance of high visibility safety garments is recommended. Garment soiling, colour fading of background high visibility material, abrasion and damage to retro-reflective strips all affect the high visibility performance of safety garments.

Employers and wearers of high visibility safety garments must be aware of the condition of any such garment on the day it is being worn. Garments must be inspected on a regular basis and replaced if they are badly damaged, soiled or faded, or the retro-reflective material has ceased to function.

Note: Refer also to subsection C19.3.6 Evaluation guide: High visibility garments.

To maximise durability of high visibility garments:

  • high visibility garments be kept clean by washing or cleaning as regularly as is practicable ensuring that manufacturer’s instructions are noted and followed
 
   


where ever practicable garments should be stored in such a way as to limit fading of high visibility background material especially fluorescent colours. When not in use place in a dark location away from natural light. High visibility background material colour, especially fluorescent colours, fade when left in natural daylight and especially in direct sunlight.

 

B3.6  Optional illuminated attachments

 
   

 

In specific circumstances within a worksite it may be appropriate to  enhance personal night-time/low light retro-reflective garment conspicuity with the addition of a self illuminating system that will attach to an approved high visibility garment that already complies with one of the options specified in subsection B3.4 Garment design

Such circumstances would normally be limited to specific locations within a worksite where moving vehicles and or equipment do not have or may not be operating an appropriate head light system that is necessary to provide retro-reflective light back to the driver of such vehicles or equipment. In areas where headlights are active the retro-reflective performance provides worker conspicuity and this will typically overpower an illuminated attachment.

The wearer of any such approved system must be aware that its performance is limited and will only be visible to a vehicle or equipment operator when positioned within the driver’s line of sight. The wearer must be instructed to be vigilant whenever working or moving behind operating vehicles that may be reversing and equipment that may swing through an operational circle.

Equally the wearer of an approved illuminated attachment must be responsible for ensuring it is fully charged and suitable for use at the time it is being used and that site management or the STMS is aware of its use on site.
