Rated to shelter 47 people at FEMA occupancy and up to 80 at maximum capacity, the TornadoLock™ CSB3008 is a transportable 8′ × 30′ solid-steel storm shelter available for rent. Its integrated ballast base anchors with helix augers or concrete piers, so it deploys without a poured slab and relocates when the oil and gas project moves. Two 36-inch ICC 500 certified exit doors provide code-compliant egress, and the unit is certified to FEMA P-361 and ICC 500 and rated for EF-5 winds up to 250 MPH.
300 sq ft of welded steel protection on an integrated transport base, engineered to FEMA P-361 and ICC-500 criteria for EF-5 events at 250 MPH. The 10-foot width gives a squarer interior than our long-format units, protecting a full shift on sites where a narrower footprint would feel cramped.
Both entry points are ICC-500 code-compliant and debris-impact rated, with three stainless sliding locks apiece, six total, every one operated from inside. The shelter cannot be locked from the outside, and it's rated to remain operable after impact so nobody is sealed in waiting on rescue.
Occupancy runs off the FEMA and ICC-500 formula: 5 sq ft per person for design, 3 sq ft per person at maximum. Bench seating is integrated into the shell rather than added after, high-grit flooring handles wet boots, and ADA full-size access doors are standard per ICC-500.
Roof-mounted solar and a backup battery keep the interior lit through a grid outage, so the CSB3010 works whether or not the building beside it still has power. Steel-plate-shielded vents meet ICC-500 net-free-area for natural ventilation while resisting debris and wind-driven rain.
1/4-inch structural steel plate in ASTM A36 and A572, solid-welded across wall, roof, and floor, with an interior truss system engineered for extreme load at 250 MPH. This is not a converted shipping container or a light-gauge storm box; the engineering is independently third-party reviewed against published standards.
The CSB3010 ships on its own transport base and sets on prepared grade — no poured foundation, no cure time before it's ready for occupancy. Add CS units later to phase capacity as headcount grows, a modular path that beats over-building a single site-constructed safe room up front.
Engineered, built, and independently third-party reviewed to recognized life-safety standards for violent tornadoes.

Occupancy is calculated by the FEMA / ICC-500 method — protected area divided by 5 sq ft per person for design occupancy and 3 sq ft per person for maximum capacity. Usable-area deductions for fixtures and accessibility are applied per the site’s certified plan.
Engineered to the standard, not to a price point. This is not a converted shipping container or a light-gauge storm box.
Designed to FEMA P-361 and ICC-500 criteria for EF-5 / 250 MPH events, with engineering independently third-party reviewed.
A ¼" welded steel envelope in structural ASTM A36 / A572 — built to resist wind-borne debris, the true killer in a violent tornado.
300 sq ft yields 60 FEMA-design / 100 maximum occupants, served by 2 code-compliant doors and engineered ventilation — no guesswork.
An integrated transport base ships, places, and protects without a poured foundation — ideal for rentals, field ops, and phased build-outs. Nationwide.
EF-5 shelter, large-hail and high-wind refuge, and a hardened multi-use field facility — all in a single unit.
Use the free Tornado Shelter Planner to size occupancy, choose a model, and build your emergency plan — or talk it through with a US Tornado Shelter specialist.
The same sealed steel envelope that stops 250 MPH debris keeps out rain, hail, heat, and cold — so the CSB3010 doubles as a hardened field asset between storms.
Add lighting, outlets, and equipment power to turn the unit into a working field station.
Heating/cooling provisions create a warm-up / cool-down station for crews in extreme heat or cold.
Because it’s already the crew’s break room, it’s staffed and occupied the moment the sirens sound — zero travel time to shelter.
Scroll through the engineered features that protect your people — from the welded steel envelope to the anchorage that keeps the CSB3010 planted through an EF-5 event.
300 sq ft of welded steel protection on an integrated transport base, engineered to FEMA P-361 and ICC-500 criteria for EF-5 events at 250 MPH. The 10-foot width gives a squarer interior than our long-format units, protecting a full shift on sites where a narrower footprint would feel cramped.
US Tornado Shelter units are engineered to ICC-500 and FEMA P-361 compliant air circulation and ventilation requirements for each shelter's occupant load.
The CSB3010 ships on its own transport base, so there is no poured foundation and no cure time on your site. The unit is set on prepared grade and leveled, which is what makes a rental deployment possible in the first place.
These panels charge the emergency battery backups for our interior solar lighting. This ensures your lights are ready anytime they're needed.
Our heavy steel storm rated doors have been impact tested and approved to meet EF-5 tornado rated protection.
Each door is heavy gauge 1/4-inch plate steel construction with added structural reinforced framing across the door for extra security and impact safety.
Each access door has three (3) 1-inch stainless steel sliding security locks. These locks ensure no debris impact will shudder the door open in an extreme tornado event.
Integrated bench seating is standard in all our shelters, running along both side walls as a comfort feature when occupied. A rental unit is built to the same interior specification as a purchased one.
The same high-grit surface is used on the interior floor as on the exterior transport base foundation. This helps occupants keep traction when entering and repositioning inside the unit if shoes or surface become wet.
Beyond the 1/4-inch solid plate steel shell, our shelters use premium steel reinforced structural trusses throughout, creating extreme load bearing capacity for impact, debris, and extreme conditions.
On both sidewalls you'll find handrails helping standing occupants find comfortable positions and support without coming into contact with the external shell wall.
Our shelters come standard with battery backup solar lighting for off-grid emergency use.
Emergency lit exit signage is standard at each access door on our tornado shelters.
A privacy screen for the emergency toilet facilities is provided in each shelter with toilet facilities.
Emergency toilet facilities are available for any unit and included standard on larger capacity shelters.
