Safety Storage/FPI offers the DOCS drive on/off containment system for field fueling and maintenance of heavy-duty military and industrial vehicles. It features a proprietary self-contained DOCS-LOC certified filtration system that automatically separates oil and water in compliance with EPA storm water regulations. No other add-on oil/water separation system is required. The pre-fabricated DOCS systems are easily moved, installed, and ready to operate. Systems are constructed of heavy-gauge sheet and structural steel treated with a chemical-resistant coating. Other features include drive-on ramps with all-hours reflective safety edges, corrosion-resistant sumps, and optional canopy. For more information call (800) 344-6539 or visit www.safetystorage.com.
