Confined Space Access Platforms
Confined space access platforms provide safe, engineered structures to reach and work at the entry points of tanks, vessels, pits, and other confined spaces — positioning personnel at manways, hatches, and access openings with stable footing and fall protection. Confined-space work is high-risk, and the access to it is often the first hazard: reaching a tank manway or a pit opening from ladders and improvised platforms adds fall risk to an already demanding job. A confined space access platform delivers a guarded working position at the entry point, engineered to the tank or vessel geometry and the opening location. Modular Solutions builds each platform from T-slot aluminum, shaping the deck and access to reach the confined-space entry safely, with guardrails, gates, and slip-resistant decking. The platform supports safe entry, attendant positioning, and equipment staging at the opening. Note that the platform provides safe access to the space; confined-space entry procedures, atmospheric monitoring, and rescue provisions remain governed by your confined-space program. For operations accessing tanks, vessels, and pits, confined space access platforms make the approach to confined-space work a safe, guarded, engineered part of the procedure.

Key Features
Engineered around your application, environment, and constraints — not a catalog template.
Reaches the Entry Point
The platform positions personnel at tank manways, hatches, and confined-space openings with stable footing.
Shaped to the Vessel
Deck and access are engineered to the tank, vessel, or pit geometry and opening location.
Guarded Working Position
42-inch guardrails, gates, and toe boards engineered to align with OSHA 1910.29 at the access position.
Attendant & Staging Support
Supports safe entry, attendant positioning, and equipment staging at the opening.
Slip-Resistant Decking
Serrated or grated decking for secure footing around the entry point.
Bolted & Reconfigurable
Installs around the vessel and reconfigures as access needs change — no welding.

Why Choose Modular Aluminum T-Slot Construction
Modular aluminum T-slot platforms bolt together without welding and reconfigure without cutting — giving you a purpose-engineered specialty structure today that adapts through every process, environment, and layout change without scrapping steel. Aluminum is the material advantage for specialty applications: it will not rust or shed, resists corrosion in chemical, coastal, washdown, and cleanroom environments, is lighter for heavy-duty and rooftop installations, and anodizes for further protection. Built from 45 Series T-slot extrusion with an integrated 40mm round handrail system, guardrails, decking, and accessories are engineered to the application, and the structure ties into our stair, platform, and guarding ecosystem. Every specialty platform is engineered and manufactured in-house in Auburn Hills, MI so the solution fits your exact requirement rather than forcing your operation to fit a catalog.
Design & Engineering Considerations
How our engineers approach each specialty platform project.
- Vessel and entry survey - We map the tank, vessel, or pit geometry and the entry-point location.
- Access design - The deck and access are engineered to reach the opening safely with a guarded working position.
- Attendant and staging - Positions and staging for attendants and equipment are designed in.
- Environment fit - Weather-rated and corrosion-resistant provisions for process and outdoor vessels.
- Program coordination - The platform supports, but does not replace, your confined-space entry program.
Safety & Compliance Considerations
Every structure is engineered to align with OSHA 1910.28 walking-working-surface and 1910.29 guardrail criteria; installed compliance is verified with your safety authority.
- 42-inch guardrails, toe boards, and gates at the access position engineered to align with OSHA 1910.29.
- Stable guarded working position at the confined-space entry point.
- Slip-resistant decking for secure footing around the opening.
- Structure supports safe access; confined-space entry, monitoring, and rescue remain per your OSHA 1910.146 program.
- Installed compliance verified with your safety authority and confined-space program.

Frequently Asked Questions
Common questions about confined space access platforms design, environment, and compliance.
What is a confined space access platform?
It is an engineered structure that provides safe access to the entry points of tanks, vessels, pits, and other confined spaces — positioning personnel at manways, hatches, and openings with stable footing and fall protection. It addresses the access hazard that surrounds confined-space work.
Does it make confined-space entry itself safe?
The platform provides safe, guarded access to the entry point and supports attendant positioning and equipment staging. Confined-space entry procedures, atmospheric monitoring, and rescue provisions remain governed by your confined-space program under OSHA 1910.146.
Can it be shaped to our tank or vessel?
Yes. We engineer the deck and access to the tank, vessel, or pit geometry and the opening location, so the platform reaches the manway or hatch with a stable, guarded working position.
Can it support attendants and equipment?
Yes. We design guarded attendant positions and staging for entry, monitoring, and rescue equipment at the opening, supporting your confined-space entry procedures.
Is it suitable for outdoor process vessels?
Yes. We provide corrosion-resistant, weather-rated configurations for outdoor tanks and vessels, with drainage decking and weather-rated hardware.
Are these platforms fall-protected?
Yes. Guardrails, toe boards, and gates at the access position are engineered to align with OSHA 1910.29 fall-protection criteria. Installed compliance is verified with your safety authority.
