Some of the dirtiest surfaces in your plant are the ones nobody can get to — the inside of a silo, the walls of a process vessel, a kettle forty feet up, the structure above a production line. We reach them on rope instead of scaffolding, and clean them with dry ice so nothing has to be carried back out.
Most plants don't have a cleaning problem in these spaces — they have an access problem, and the access cost is what kills the work order. Rope access removes the scaffolding bill; dry ice removes the cleanup that follows.
A technician on rope is positioned where the work is in hours, not days — no erect-and-dismantle cycle occupying the asset while nothing gets cleaned.
Grit and water both leave you with something to remove from a space you needed a permit to enter. Dry ice sublimates — only the removed contamination remains.
Confined space work runs under your entry program: permit, atmospheric monitoring, ventilation, attendant, retrieval and an agreed rescue plan.
No rinse step and no media recovery means fewer entrant-hours inside — which is the number your safety team actually cares about.
Dry ice lifts buildup without eroding vessel walls, liners or weld seams — you clean the deposit, not the equipment.
Descending into a silo or vessel is rope access and confined space entry simultaneously. We plan it as one operation, not two.
Industrial kettle cleaning performed via rope access at the CertainTeed (Saint-Gobain) plant in Phoenix. Complex machinery cleaned in place — no disassembly, no scaffolding build, no secondary waste stream. Alpine's largest documented single project.
Yes. Dry ice sublimates into CO₂ gas, which is heavier than air and displaces oxygen in an enclosed space. That is a genuine confined-space hazard, and any contractor who waves it away should not be entering your vessel. It is also entirely manageable — which is the whole reason this is a planned, permitted, monitored operation rather than someone with a blast hose and a good attitude.
O₂ and CO₂ monitored before entry and continuously throughout the job — not spot-checked at the start and forgotten.
Air movement sized to the volume of the space and the blast rate, so sublimated CO₂ is removed as fast as it is produced.
We work under your site's confined space entry program and permit system, coordinated with your entry supervisor.
An attendant stationed outside in constant communication with the entrant, with a retrieval system rigged before anyone enters.
Rescue arrangements settled with your team before entry — never worked out after something has already gone wrong.
Scope, monitoring notes and before/after photography provided for your job file and audit trail.
For most interior and at-height cleaning, the cleaning is the cheap part. What you are really pricing is how a person gets to the surface and how long the asset is tied up while that happens.
If access is the reason a surface hasn't been cleaned in years, it's probably a job for us.
Interior walls, agitators, baffles and internals — cleaned in place with no wash water to pump out afterward.
Bridged and caked product removed from walls and cones, reached on rope from the top rather than from a build.
The scope behind our largest documented project — complex machinery cleaned at height without disassembly.
Interior duct runs, plenums and stacks where buildup restricts flow and conventional access is impractical.
Below-grade spaces with restricted entry, cleaned without introducing water into an area that already drains poorly.
Rafters, beams and equipment reached on rope where lifts can't position. See combustible dust & high-ceiling cleaning.
Yes — and anyone who tells you otherwise should not be entering your vessel. Dry ice sublimates into CO₂ gas, which is heavier than air and displaces oxygen in an enclosed space. That is exactly why confined space dry ice work is a planned, permitted, monitored operation: continuous O₂ and CO₂ monitoring before and throughout entry, forced-air ventilation and extraction sized to the space and the blast rate, an attendant stationed outside, and a rescue plan agreed before anyone goes in.
Scaffolding a tank interior or a high kettle can cost more and take longer to erect and dismantle than the cleaning itself, and it occupies the space for the duration. Rope access puts a technician exactly where the work is within hours, with a far smaller footprint — which usually means the asset comes back online sooner.
Yes — that combination is much of what we do. Descending into a silo, tank or vessel to clean interior walls and structure is rope access and confined space entry at the same time, and it is planned as one operation: entry permit, atmospheric monitoring, ventilation, fall protection and a retrieval system rigged before entry.
Tanks, silos, hoppers and bins, process vessels and kettles, ductwork and stacks, pits and tunnels, plus overhead structure reached on rope rather than from a lift. If access is the reason a surface has not been cleaned in years, it is probably a job for us.
Because nothing has to come back out. Water leaves you with contaminated wash water to pump and treat, and grit or media leaves spent abrasive to shovel out of a space you just spent a permit getting into. Dry ice sublimates — only the removed contamination remains, which means less time in the space and no secondary waste stream.
Yes. We work under your confined space entry program and permit system, coordinate with your entry supervisor, and follow your site's rescue arrangements. If you need documentation for the job record, we provide scope, monitoring notes and before/after photography.
We serve industrial facilities throughout the Phoenix metro and travel for large-scale access work. Our largest documented project — the CertainTeed / Saint-Gobain kettle — was rope access work in Phoenix.
