How long does the safety flag need to be?
When we talk vehicle safety flags, there can sometimes be confusion.
For starters, it’s never just about the flag. An assembly comes with flag, pole, and base – all of which play an important part in keeping a vehicle safely visible.
Secondly, the increasing popularity of safety flags mounted on LED poles has given that part of a flag assembly more importance.
But for all the discussion we can have around the flag pole, there’s one question that counts more than anything else:
How long is long enough?
Well, to answer that, we’re going to go through some “rules” that help you determine what you’ll need, as the answer is a little more complex than you’d first think…
Rule 1: The Mine Site Standard
To comply with most Australian mine site standards, the flag pole generally stands between 3.2mtrs to 4.2mtrs from the ground to the very top of the flag pole.
Rule 2: The Mounting Points
So knowing the height the safety flag has to reach, you must then work out where the flag will be mounted to achieve that. The two mounting points on any vehicle are the bull bar and the headboard / roof.
Because the bull bar is lower, flag pole lengths for this mounting tend to be longer. The most common lengths for this are 2.4, 2.5, and 3 metres.
With the headboard higher, the flag poles are smaller, with common lengths being 1.2, 1.5, 1.8, and 2 metres.
Rule 3: When In Doubt, Ask The Mine Safety Officer
Having said all that, every mine site can have their own specifications that may vary slightly to the basic site standard.
So, if you’re unsure about what length your safety flags have to be meet the site standard, simply ask the mine safety officer. They should be able to give you the exact details, or even better, a spec sheet for reference.
Rule 4: Under and Over
An exception to the 3.2mtr to 4.2mtr rule are underground mines.
This is due to the confined space, leaving flag poles to be very short – in most cases, no more than 60 or 90cm.
The longer flag poles are used only around open cut and above ground mine sites.
