Your coveralls are high-viz. Your backpack isn't.
Underground attire is built for visibility — orange coveralls with 2" reflective striping across the back, the arms, the legs. Put a standard pack on, and the striping across your back disappears under it.
The pack carries the striping it covers.
OPC's Hi-Viz backpacks put fluorescent fabric and 2" reflective tape on the pack itself, so the high-visibility coverage a standard pack takes away stays on the worker — visibly safe with the pack on. Two models — a 26 L daypack and a 32 L pack with helmet pouch and MOLLE points. Safety equipment, not personal kit — both carried under OPC part numbers.
The striping stays visible with the pack on.
Hi-Viz Orange Utility Daypack, 26 L
High-visibility fabric with a reflective X pattern, padded harness with sternum strap, action-back carry, internal organisation, side utility zip pocket and mesh bottle pocket. Sized for supervision rounds and task-specific carry.
Hi-Viz Orange Utility Backpack, 32 L
Abrasion-resistant body, 2" reflective tape front and rear in an X pattern, ergonomic padded harness with sternum and hip straps, front helmet pouch, MOLLE attachment points and an oversized main zipper. Sized for daily respirator and tool carry.
Fluorescent fabrics and 2" reflective tape patterns meeting CSA Z96 high-visibility accessory requirements. Supplied as accessories: they supplement required high-visibility apparel and do not replace it.
Also available through Soucie Salo Safety.
A dry shotcrete helmet out of service stops a face.
Replacing it is full price — and often the helmet does not need replacing. It needs a lens, a seal, a valve, or a battery that still holds a shift.
OPC inspects, repairs and rebuilds dry shotcrete helmet systems: lens and visor components, seals and airflow valves, internal battery replacement, and external battery fitment. Complete rebuilds and refurbishments, returned plug-and-play, on a 7–14 day turnaround, under replacement cost.
OPC does not represent a single manufacturer. Parts are sourced across systems, including the hard-to-find ones, and the work is judged on reliable airflow, clear vision and protective consistency — not on whose badge is on the shell.
Technical support on equipment set-up and parts selection, attached to the repair.
A dry shotcrete helmet system in service.
Charge the battery. Not the helmet.
The battery a dry shotcrete helmet ships with is internal. When it runs down, the helmet goes with it — up to a charging station, out of service until it comes back. One flat battery takes the whole helmet off the job.
OPC fits a compact external pack instead. It holds a longer charge than the internal battery, and it swaps on the fly: a fresh pack goes on and the work carries on. The helmet stays at the job site, underground, where it is needed. Nothing travels to a charger but the battery.
Fitted to the helmets you already own, with power supply optimisation for 5+ hours of service. Returned plug-and-play.
Filters, chargers, plugs, lenses, visors, seals and airflow valves — supplied on their own.
No rebuild required, no helmet off site. OPC sources across systems, including the parts that have become hard to get.
Filters are the repeat line
Consumed on a cycle, and the item most likely to put a helmet out of service for a trivial reason. The easiest thing on this page to put on a standing reorder.
Put it on a safety budget, not a personal one.
