At what point should long sleeved High Visibility clothing become manadatory over short sleeved vest type?

Is this dependant on road type (i.e. 60mph or over requires long sleeves?)

We supply both to our operatives but have noticed the short sleeved vests are preferred during the nicer weather (obviously) but I believed the long sleeved vests must be worn on certain types of road, am i correct?


Thanks

This all relates to EN471:2003 with regards to hi-vis clothing:
There are 3 classes of garment type based on the levels on conspicuity they provide.On all garments the retro-reflective tape must not be less than 50mm wide. Basically you will need Class 3 garments if working on dual carriageways (50mph+)

CLASS 3: Highest Level of conspicuity
Minimum background material 0.8m2
Minimum Retro-reflective material 0.2m2
i.e. Jackets with sleeves to be worn in accordance with Clause 4.2.4 and to Class 3 on dual carriageway roads with a speed limit of 50mph or above

CLASS 2
Minimum background material 0.5m2
Minimum Retro-reflective material 0.13m2
i.e. 2 Band & Brace Hi-vis waistcoat

CLASS 1
Minimum background material 0.14m2
Minimum Retro-reflective material 0.10m2
i.e. Minimal risk such as off road activities. Hi-vis trousers will commonly meet this standard when worn separately from upper garments.

High Visibility Clothing conforming to BS EN471:1994, Class 2 or 3, which must be worn at all times.

Jackets with sleeves Class 3 must be worn on dual carriageway roads with a speed limit of 50 mph or above, unless operatives stay within the working space at all times.
