Solution by job

Sign off the work zone

To sign off a work zone, set up four areas: advance warning, a taper with cones or drums, the work zone and the end. SIMAQ has the full kit: 28″ (71 cm) cones, 91 cm channelizer drums with 2 reflective bands, 115 cm delineator posts, mesh, tape and reflective vests.

Also called: traffic cones, channelizer drums, delineators

Field rules

Do it right the first time

01

The taper is sized by road speed: the faster the traffic, the longer the cone funnel.

02

Clean reflective or no reflective: a dust-dulled cone at 10 pm is invisible. Wash the kit weekly.

03

Vest on BEFORE stepping out of the vehicle: the moment you leave the cab, you're on the road.

04

Working at night → drums and delineators with reflective bands, plus light on the zone: cones alone aren't enough.

Guides for this job

How to sign a single-lane closurePlan view of a two-lane road with traffic moving from bottom to top; the right lane is closed. In order, from where the driver arrives: first the advance warning zone, with a sign ahead of the work. Then the taper: a diagonal row of cones or drums that steers traffic into the other lane. Then the work zone, bounded with mesh or tape, with the crew inside wearing reflective vests. Last, the end of the closure, where cones return the lane. Distances and the number of cones depend on the traffic plan approved for the job, so the diagram has no measurements.!End of closureThe lane opensagain.Work zoneBounded with meshor tape.

FAQ

What people ask before buying

What signage equipment do I need to work on a street?

At minimum: cones or drums for the taper, delineators or mesh to close off the work zone, caution tape and a reflective vest for everyone. How many cones depends on the road speed and your project's traffic plan.

Cones or channelizer drums?

Short job, daytime, slow street → 28″ cones: quick to set and pick up. Fast road, a job lasting days or night work → 91 cm drums: they're more visible and their weighted base stands up better to traffic wind.

How many cones do I need to close a lane?

It depends on the road speed: the faster the traffic, the longer the taper and the more cones. Your project's approved traffic-management plan sets it; the advisor helps you build the kit from that plan.

Why can't a cone be seen at night?

Because the reflective band is dirty: a dusty cone barely reflects headlights. Wash cones and drums every week and replace any with a torn band.

What reflective vest should you wear on site?

A mesh vest with reflective stripes, in orange or cyan — whichever contrasts most with your surroundings or your project requires. Put it on before stepping out of the vehicle, not once you reach the work zone.
