Site Rules and Safe Systems of Work
Reading the site
A safe system of work sets out how the job is done safely: traffic routes, speed limits, pedestrian segregation, designated parking and charging areas, load limits, and permit-to-work arrangements. Operators must know the site layout, one-way systems, crossing points, blind corners, overhead obstructions and the location of fire points and first-aid equipment. Site induction and signage communicate these rules, and you are expected to follow them even when a shortcut seems quicker.
Pedestrians and segregation
Pedestrians are the highest-risk group. Physical segregation (barriers, walkways, crossing points) is preferred; where it is not possible, use mirrors, warning devices, speed control and eye contact. Never assume a pedestrian has seen you. Sound the horn at blind corners and doorways as required by site rules, and travel at a speed that lets you stop safely within the distance you can see to be clear.
Traps
Questions often test whether site rules or general good practice take priority - the site's safe system of work applies in addition to, not instead of, safe operating practice. Another trap is the horn: it is a warning device, not a right of way. Also watch for questions about pedestrian priority at crossings and about reversing - reversing should be minimised, and where unavoidable, use aids, spotters and slow speed.
Rule of thumb
"See and be seen" - if you cannot see clearly ahead, slow down, sound a warning where the site requires it, and use a spotter for blind reversing.
Worked example
At a blind corner the site rule requires a horn warning. The correct action is to slow down, sound the horn, and proceed only when satisfied the way is clear - not to assume the horn gives priority.
