Onsite signage: legal obligations

What type of worksites are we talking about?
Defining a 'worksite'
Worksites on private land
Worksites all or partly situated on public land
What do the regulations say?
This has the following aims:
- informing road users that the layout has been temporarily modified
- guiding traffic appropriately in a diverted manner
- inducing people to modify their behaviour - e.g. speed and clearance for vehicles, crossing times and places for pedestrians
Onsite signage: basic principles
Appropriateness of signage
- the type of roadway, e.g. single vs dual carriageway, A-road vs B-road vs unnamed country lanes, etc.
- the density of traffic (vehicles and pedestrians) making use of the site area, as well as the type of vehicles, i.e. if there are large numbers of motorbikes or heavy goods vehicles in play
- the layout and space available - width of lanes, any obstacles, visibility etc.
So that road users respect temporary signage (which they may not be in the habit of), it's imperative that:
- the instructions given are completely justified in the circumstances
- the signage is updated regularly as works progress
- signs are removed when they cease to apply, and particularly when works are completed
Readability of warning signs
- it should be installed carefully at the correct height, avoding visual obstacles like trees, etc.
- it mustn't flood the user with instructions - maximum of two signs in the same place
- it must be clean, in good condition and above all confirm to regulatory standards concerning different types of signage - sheet metal signs, lighting etc.
Making personnel visibleApart from informative road signage, people coming and going onsite must themselves be 'signposted'.
Signposting a worksite in 4 steps
1. Protecting personnel
This is the first step since protecting people is always the priority. Anyone working onsite must be equipped with the appropriate PPE at all times. Anyone working on or nearby roadways or access routes must wear appropriate hi-vis clothing.
2. Signposting entryways
- 300m before entering the site, a sign to indicate that works are coming up
- 200m before entering, a sign to indicate that the roadway has been modified
- 100m before entering, a sign giving the new temporary speed limit
3. Signposting route changes
4. Signposting the end of works
It's just as important to inform road users that the hazard zone is over. There should be a sign placed immediately at the end of the works area saying very plainly "end of works".
Onsite signage: special cases
- If the worksite is no more than 50m long and the traffic is under 100 vehicles per hour, you just need a few basic signs (indicating priority of access)
- For worksites up to 1200m in length with traffic rates up to 1000 vehicles per hour, a minimum of two attendants communicating by radio are required
- For sites 500m (max) in length with traffic rates of 800 vehicles per hour, freestanding traffic lights should be used.

Electrician by trade, I first worked in industrial estates where I installed, wired and fixed a large number of electrical installations. After this, I managed a team of electricians for this type of work. 10 years or so ago, I turned to building and construction. From the modest family home, to gyms and theatres; I have been able to coordinate, audit and organise all sorts of construction sites.
for 4 years now, I am restaoring and bulding an extrension to a bungalow in the heart of the welsh countyside. My experience in manual work and my knowledge means I am proud to be of service. Terraces, interior design, roofing, plumbing, electricty, anything goes! We have, my wife, daughter and I, built almost everything we have from scratch!
