Safety Halo™: laser and LED exclusion zones for mining machinery

Safety Halo™ projecting an exclusion zone around heavy machinery on a mine site

Safety Halo™ is an Incident Zero (Australia) system that projects a laser or LED exclusion zone onto the ground around mobile plant, and the zone moves with the machine. The Class 3R laser marks it at up to 50 m, the Class 2 at up to 10 m, and the 30 W LED covers compact equipment. Every model is IP68 rated, and Endeavant S.A.C. distributes them in Peru.

Why don't fixed barriers protect people around moving machinery?

The danger zone around an excavator, loader or forklift changes with every manoeuvre, and a cone or chain marks a perimeter that stops meaning anything as soon as the machine moves. From the cab, the operator can't see everything at ground level, and a worker on foot may not realise they are inside the machine's swing radius. Fixed barriers also get moved, forgotten or never put back.

LED mining vehicle ID tells you which machine is which, but it doesn't show where the risk is. That takes an exclusion zone that travels with the machine.

How does a laser exclusion zone work?

The Safety Halo™ laser exclusion zone mounts on the machine and projects laser or LED light lines around it, marking on the ground the perimeter nobody should cross while it operates. The zone moves with the machine and shows the risk in real time through every manoeuvre.

The design is grounded in neuroscience: an obvious "red zone" triggers the natural response in operators and pedestrians to step away from danger. According to Incident Zero it is understood regardless of language or education level and needs little training. The colour is highly saturated, visible even to people with red-green colour blindness, and it sets the exact distance to keep from the machine.

The line also organises the work: it guides trucks to the ideal distance from the excavator and helps them line up at ROM hoppers.

Which Safety Halo™ models are there?

Safety Halo™ has three models that share the same principle and install with the same kits. The choice depends on machine size and how far the zone needs to be projected:

The Laser Safety Halo™ weighs 0.38 kg, has a 6063 aluminium housing and a 304 stainless steel bracket, and is made in the USA. The LED is vibration tested to 7 g, with a powder-coated cast aluminium body and a polycarbonate lens.

Laser or LED: which suits each machine?

Laser projects further; LED draws an even zone around compact equipment. Incident Zero recommends them as follows:

  • Laser Safety Halo™ Class 3R (long range): for large-scale plant: shovels, draglines, dozers, loaders and haul trucks. Projects to under 50 m (model LSHx-B).
  • Laser Safety Halo™ Class 2 (mid range): 1:1 line to mounting height: mounted 3 m off the ground, it draws a 3 m line. Projects to under 10 m (model LSHx-A).
  • LED Safety Halo™ SHXL-30 (compact plant): for forklifts, skid steers, small excavators, rollers, compactors, telehandlers, pavers and aisle marking in workshops or yards.

What do the red, green and blue colours mean?

All three Safety Halo™ models come in red, green and blue, and each colour says something different: red marks a danger zone, blue is a presence warning and green shows a boundary or guide, such as a truck alignment line at a ROM hopper or the limit between machine and personnel underground. On the lasers the wavelengths are 638 nm (red), 520 nm (green) and 450 nm (blue).

How is Safety Halo™ installed on a machine?

Laser and LED units ship as plug-and-play kits of 2 to 7 lights. Each kit includes the lights with sealed Deutsch DT2 connectors and 1.2 m sheathed cable, an IP68 junction box with surge protection and a 40 A rectifier, and 304 stainless steel brackets with 3M VHB structural adhesive for horizontal or vertical mounting. Installation takes eight steps:

  1. Clean the area with alcohol: no dust or grease.
  2. Peel the adhesive liner and stick the bracket in place.
  3. Fix the light to the bracket with the supplied bolts.
  4. Peel the junction box adhesive and fix the box in place.
  5. Connect the junction box input cable to the power source.
  6. Connect the lights to the box with the supplied connectors.
  7. Secure the cables to the machine, away from areas where they can be damaged.
  8. Switch the lights on.

Thanks to its low draw, the laser can run off the machine's existing lighting circuits; each light takes a 1 A slow-blow fuse. As with any laser product, avoid direct eye exposure to the beam.

What certifications and warranty does Safety Halo™ carry?

  • Laser Safety Halo™: CE, EMC (EU) and FCC; laser safety to EN/IEC 60825-1:2014 and AS/NZS IEC 60825.1; DO160; IP68. Two-year manufacturer's warranty on parts and labour, excluding impact damage, misuse or operation outside specification.
  • LED Safety Halo™: ECE R10, CE, EMC 2014/30/EU and IP68, with EMC Class 4 anti-interference performance so it doesn't disrupt machine systems.
  • Junction box: IP68, UL E78996 and RoHS 2002/95/EC.

Where is Safety Halo™ used?

According to Incident Zero, Safety Halo™ runs in mines in Australia and Chile, in open pits, underground, at ROM hoppers and on night shift, fitted to front-end loaders, excavators, telehandlers, elevated work platforms and forklifts. In Peru it applies to the same situations: loading faces, maintenance workshops, yards and warehouses where people and machinery share space.

An exclusion zone is one layer of site traffic management. To see how it fits with equipment ID, read our guide to mining vehicle signage. On light vehicles and crew buses, Endeavant smart cameras alert the driver in the cab while Endeavant's 24/7 Control Center validates every event.

Each model is sold as a single light or as a kit, and we help you set the number of lights, colour and position for each machine: forklift, loader, excavator, dozer, grader, crane or dragline. Part numbers are on the Safety Halo™ page, and the rest of our range is under mining safety solutions.

Safety Halo™ FAQ

What is Safety Halo™ and how does it work?

Safety Halo™ is an Incident Zero (Australia) system that projects laser or LED light lines onto the ground around machinery, marking an exclusion zone that moves with the machine. The obvious "red zone" triggers the natural response to step away from danger and needs little training.

What is the difference between laser and LED Safety Halo™?

Laser Safety Halo™ projects further: under 50 m for Class 3R and under 10 m for Class 2, for large-scale plant. LED Safety Halo™ SHXL-30, at 30 W and 1,950 lm, draws an even zone around compact equipment such as forklifts and skid steers.

Can Safety Halo™ handle mine-site conditions?

Yes. Every Safety Halo™ model is IP68 rated against dust and water. The laser has a 6063 aluminium housing and 304 stainless bracket; the LED is vibration tested to 7 g and runs from −40 to +65 °C.

What colours does Safety Halo™ come in?

All three Safety Halo™ models come in red, green and blue. Red marks a danger zone, blue is a presence warning and green shows a boundary or guide, for example to line up haul trucks at ROM hoppers.

How is Safety Halo™ installed?

Safety Halo™ ships as plug-and-play kits of 2 to 7 lights, with Deutsch DT2 connectors, an IP68 junction box with surge protection and 304 stainless brackets with 3M VHB adhesive. Installation takes eight steps, from cleaning the surface to switching the lights on.

Who distributes Safety Halo™ in Peru?
