Confined Space Tank Cleaning

When a tank, silo, or underground vault needs to be cleaned, the confined space inside presents real and immediate dangers—toxic atmospheres, engulfment hazards, and limited entry and exit points. Rhino Services approaches every permit-required confined space job with rigorous safety protocols and a crew that lives and breathes those standards.

Our technicians are fully trained and equipped for the challenges of confined space entry. Before anyone steps through a manway, the team establishes continuous atmospheric monitoring to detect low oxygen, flammable gases, or hazardous vapors. We set up forced-air ventilation systems to maintain a safe breathing environment, and we deploy a full rescue retrieval system with a dedicated attendant standing watch at all times. These procedures comply with OSHA confined space regulations and NFPA best practices, giving you the documentation and peace of mind that the job is being done right.

Once the space is verified safe for entry, crews get to work removing the materials that brought you to us in the first place—built-up sludge on the tank floor, hardened scale on interior walls, or product residues that contaminate future batches and prevent accurate inspections. Using vacuum systems, hydroblasting, and manual tools as the situation demands, we extract every pound of material and leave a clean, residue-free interior.

This service supports routine maintenance outages where accumulated solids must be cleared, as well as pre-inspection cleaning that lets your integrity inspectors see every weld, seam, and pitted area without obstruction. Refineries, chemical plants, wastewater facilities, and food processors all rely on Rhino to turn a hazardous, confined entry into a predictable, efficient cleaning event that restores the vessel to full functionality without a single safety incident.
