Alberta’s pipeline sector is moving again. With new oilfield and pipeline projects recently approved across the province, construction and operations teams are returning to the field — and with them comes the full range of access challenges that any active pipeline site presents. Workers need to cross over pipe runs and berm walls. Technicians need safe, stable platforms to reach valves, actuators, and instruments. Metering stations need compliant work surfaces built to support routine inspection and maintenance.
Modular access platforms address all of these needs faster and more cost-effectively than most project teams expect. Here’s what they are, where they fit on a pipeline site, and how Northern Platforms can get them to your project.
Three Applications for Modular Platforms on Pipeline Projects
Pipeline sites create access demands at every stage of construction. The three most common requirements we see on Alberta pipeline projects are crossovers, valve access platforms, and metering station decks.
Pipeline Crossovers
Above-ground pipe runs, containment berms, and valve manifolds create obstacles that workers need to cross safely, repeatedly, and quickly. When no crossover is in place, workers might resort to unsafe crossings. This is when slips, trips, and falls happen.
A modular pipeline crossover provides a safe stairway over the obstruction. ErectaStep crossover units are available in configurations to accommodate a wide range of pipe and berm heights, with anti-slip grating, full guardrails, and self-closing safety gates at both landings.
Because the platforms bolt together without welding or cranes, they can be positioned and reconfigured as construction progresses and pipe routing changes. When the project phase is complete, the same units can be disassembled and redeployed elsewhere on site or at a different facility entirely.
Valve Access Platforms
Isolation valves, check valves, and actuators are often located at height, in tight quarters, or in positions that require a worker to lean, overreach, or improvise access. On the other hand, a properly configured valve access platform puts a stable, compliant work surface directly at the valve—at the right height, with handrails and a safety gate, and enough deck space for a technician to work with both hands.
Metering Station Platforms
Much like valve access platforms, safe access to metering stations is crucial on active worksites. Modular platforms for metering station applications can be configured to provide access at multiple elevations within a single station, with interconnected walkways, stairs, and landings sized to the specific equipment layout. The ErectaStep system’s modular design means platforms can be specified to fit around existing piping and structures without requiring custom engineering drawings — the configuration tool produces accurate schematics in hours, not weeks.
Key Features of Modular Pipeline Platforms from Northern Platforms
The advantages of modular access platforms come down to four things that matter on an active project site:
Speed. ErectaStep units are prefabricated, in stock, and ship immediately. Northern Platforms carries ErectaStep inventory in Alberta, which means no border delays and no waiting on fabrication queues. For a project with a tight construction schedule, that availability can mean the difference between a compliant site and a work stoppage.
Simplicity. ErectaStep platforms bolt together using standard tools. No welding, no crane lifts, no specialty contractors required. A small crew can assemble a complete crossover or valve access platform in hours.
Compliance. Every ErectaStep unit is OSHA and Alberta OHS compliant out of the box — guardrails, anti-slip surfaces, load ratings, and safety gates included. No additional engineering certification required for standard configurations.
Flexibility. Modular platforms aren’t single-use infrastructure. Once a pipeline construction phase wraps up, the same units can be disassembled and reconfigured for a permanent installation at the completed facility — valve access platforms around new equipment, crossovers at permanent piping manifolds, or work platforms at compression and metering stations. The investment travels with the project.

Does your operation have the equipment it needs? If not, Northern Platforms is here to help. As a leading Western Canada supplier of SafeRack and OPW products, our team specializes in building railcar loading and unloading systems that protect workers and maintain throughput at the same time. Keep reading to learn more about the different types of railcar loading arms and platforms that we offer, broken down by application.
Common equipment considerations: Loading arm, grounding/bonding, vapour management where required, overfill protection, spill containment, gangway or access platform, fall protection, heated or jacketed components
Railcar Loading Systems for Refined Fuels (Gasoline, Diesel, Jet Fuel)
Refined fuels such as gasoline, diesel, and jet fuel require loading systems that support fast, controlled, and clean transfer. Because these products are flammable or combustible, the system must be designed to reduce ignition risk, control vapours where required, prevent spills, and keep workers safely positioned during loading. Key design considerations for refined fuel loading systems include:
Type of railcar: General service tank car for flammable or combustible liquids
Type of loading: Top or bottom loading; gasoline is commonly handled with closed loading and vapour recovery (where required)
Common equipment considerations: Loading arm, dry disconnect or tight-fill couplers, vapour recovery arm or line, grounding/bonding, overfill protection, emergency shutoff system, gangway or access platform, fall protection
Railcar Loading Systems for Natural Gas/LPG (Propane, Butane)
Liquified petroleum gas (LPG) is transported in pressurized tank cars and presents a very different risk profile than crude bitumen or refined fuels. Loading systems must maintain proper pressure during loading and unloading. Additionally, platforms and racks must meet strict industry standards (NFPA 53). Key considerations for these loading systems include:
Common equipment considerations: Pressure-rated loading arm, secure couplers, emergency shutoff valves, breakaway protection, vapour return or equalization line where required, gas detection, gangway or access platform, fall protection
Railcar Loading Systems for Ammonia (NH3)
Railcar loading systems for LPG and ammonia share several characteristics. Both products are transported under pressure, both require secure connections, and both rely on closed transfer systems to maintain containment. However, ammonia introduces an additional layer of risk: it is highly hazardous to workers if released. As a result, ammonia loading systems must be designed with particular attention to leak prevention, emergency shutoff, vapour or vent management, and safe operator access. Key design considerations for ammonia loading systems include:
Common equipment considerations: Loading arm, emergency shutoff system, secure couplers, vapour/vent management, gas detection, eyewash and safety shower access, gangway or access platform, fall protection
Railcar Loading Systems for Molten Sulphur
Molten sulphur is one of the more complex bulk liquid loading applications because the product must be kept hot enough to remain in a liquid state. If the product cools during transfer, it can begin to solidify inside the loading arm, piping, valves, or railcar connection point. Details about molten sulphur loading systems:
Type of railcar: Insulated tank car designed for molten sulphur service
Type of loading: Heated top loading through the railcar hatch
Key loading concern: Maintaining product temperature, preventing solidification, managing H₂S exposure, avoiding spills or residue, and protecting operators from burns
Common equipment considerations: Steam-jacketed or heat-traced loading arm, heated piping, vapour management or venting provisions, spill control, gangway or access platform, safety cage, fall protection, eyewash and safety shower access
Crude, LPG, refined fuels, ammonia, and molten sulphur all move by rail, but they all require different infrastructure. Each product has its own requirements for tank car fittings, loading arms, vapour control, fall protection, safety systems, and more.
As a full-service provider, Northern Platforms specializes in designing and installing complete turn-key railcar loading solutions for crude oil, refined fuels, propane, butane, ammonia, molten sulphur, and more. We have nearly 30 years of experience and have worked with some of the largest industrial operations in Western Canada.

Are you looking to buy railroad blue flags for your railyard in Alberta or BC? Northern Platforms supplies a variety of railyard safety signage, including blue flags and blue lights. Keep reading to learn more about these signs, the provincial requirements in Alberta and British Columbia, and the options available at Northern Platforms. Plus, we’ll also cover some additional railcar safety equipment you can purchase for a complete, fully protected railyard.
What are Blue Flags?
Blue flag railroad safety signs are cautionary signals indicating that workers are on, under, or in the vicinity of rail equipment. They serve as a universal indicator that other workers or locomotives should not approach, move, or couple with the impacted railcar.
When are Blue Flags Required?
Blue flags are required for all rail sites whenever railcars are being worked on, loaded, or unloaded, regardless of what material is being dealt with.
Depending on your jurisdiction, there may be additional requirements or regulations that apply to blue flags on your site. For example, in Alberta, some key additional requirements include:
Placement of the blue flag on a section of track or on a railway vehicle
The same crew that places the blue flag must also remove it.
Operators must be trained on proper blue flag procedures. Written instructions are also required.
Curious about the blue flag requirements in your location? The team at Northern Platforms has extensive knowledge of safety requirements in both Alberta and British Columbia. Contact us today for more information.
Types of Railroad Blue Flags Available at Northern Platforms
While all blue flags serve the same fundamental purpose, these safety signs are available in many different options, including:
Blue Flag Signs (Daytime)
The standard railroad blue flag sign is a physical sign plate constructed of durable material, minimum 30 cm × 38 cm, printed on a blue background with the word “STOP” in white capital letters at least 10 cm high. It is mounted on a pole, affixed to the rail, positioned at right angles to the track, and raised to approximately five feet above the top of the rail so it is clearly visible to approaching movements.
Northern Platforms carries several Aldon railroad blue flag signs. Common sign plate options include “DO NOT MOVE,” “STOP – Employees Working,” “STOP – Tank Car Connected,” “STOP – Crew At Work,” and “No Locomotives Beyond This Point,” among others. Custom signage is also available, and signs can be ordered in English, French, or Spanish.
Blue Lights (Nighttime and Low-Visibility)
Under Canadian Rail Operating Rule (CROR) 26, blue flag protection requires both a blue flag by day and a blue light by night. Northern Platforms can also provide blue lights, including solar-powered, flashing, and magnetic options.

Additional Products for Complete Railyard Safety
In addition to railroad blue flags, Northern Platforms also supplies a variety of railyard safety equipment, including:
Derails
A derail is a physical mechanical device mounted to the rail that, when engaged, will intentionally guide a railcar or locomotive off the track before it can reach the protected work zone. Derails are often paired with blue flags and offer an extra layer of protection if a locomotive or car somehow passes a blue flag that should have stopped it. In this case, the derail forces it off the track rather than allowing it to continue into the area where workers are present.
Wheel Chocks
Even a small gust of wind or the vibration from a nearby loading operation can send an unsecured railcar rolling. To help prevent dangerous “runaway” situations, railcar wheel chocks are essential.
Steel-spur railcar wheel chocks bite into the rail to hold the car in place, preventing this uncontrolled movement during loading, unloading, or maintenance operations. They are available in a variety of styles, including options for both exposed rail and flush rail.
Normally, railyards use standard placards to indicate which way a track switch is thrown. While this system works during the daytime, it can create serious safety concerns at night. If an incoming crew can’t easily read the switch direction, they could send a railcar down the wrong track and directly into a loading operation. To solve this problem, Northern Platforms supplies Aldon switch cubes.
Switch cubes are illuminated and reflective indicators that clearly show which direction a switch is thrown, regardless of visibility conditions. This product comes in a variety of configurations and options and is particularly useful for facilities with multiple tracks and loading positions.

Promoting safe access is the cornerstone of all industrial sites. From routine inspections to maintenance, loading, repairs, and equipment operation, workers need reliable ways to reach the areas where work actually happens.
But safe access does not look the same in every facility. Some sites need permanent platforms built around fixed equipment. Others need mobile platforms that can move between work areas. Understanding the difference between these platform types is key to choosing the right solution for your application. In this article, we’ll break down the differences between modular, mobile, and fixed industrial work platforms, including where each option is commonly used and how they support safer, more efficient work.
What Are Industrial Access Platforms?
Industrial access platforms are engineered systems that provide safe, elevated work areas for inspection, maintenance, and operations tasks. They typically combine:
A work deck or platform
Stairs or ladders for access
Guardrails, toe boards, and gates for fall protection
Generally speaking, industrial access platforms fall into three major categories: fixed, modular, and mobile. Let’s break down some key details about all these systems.
Mobile Access Platforms
Mobile access platforms are rolling or movable platforms that can easily be repositioned to where they’re needed and locked in place during use. Typically, you’ll find mobile platforms in applications where:
The work moves around the site (e.g., maintenance on multiple pumps, valves, or vehicles)
Equipment of similar height is spread across a large area
You need temporary access during shutdowns, turnarounds, or project phases
Installing a permanent structure is not practical or cost‑effective
Some examples from Northern Platforms include:
RollaStep MP Series mobile work platforms, which combine the stability of a fixed platform with the mobility of a rolling stair. Ideal for flatbed truck loading and unloading.
SafeRack MAUI Mobile Truck Loading Platform is a mobile tank truck access platform designed for safe loading access. It includes a stable base, telescoping ladder, and safety cage, with optional powered movement for easier positioning.
While mobile platforms can be useful, they should be avoided for high-traffic sites with consistent loading and unloading operations. In these situations, opt for a permanent/fixed loading rack.
Modular Access Platforms
Modular access platforms are built from standardized, pre-engineered components, like stairs, platforms, handrails, ladders, and supports, that bolt together easily. Generally, modular access platforms are ideal for:
Sites where access needs evolve over time
Projects on tight schedules that can’t wait for custom fabrication
Facilities that prefer bolt-together, no-welding installations for safety and speed
Applications where reconfiguration and expansion are expected
Systems like ErectaStep use a small set of standard components (universal platforms, stairs, ladders, tower supports, handrails) that can be combined into almost any configuration: crossovers, valve platforms, mezzanine access, ladder platforms, and more.
In practice, modular systems cover the majority of common industrial use cases, especially for valve access, pipeline crossovers, metering stations, industrial catwalks, rooftop access, and more. However, they are generally not used for truck and railcar loading and unloading.
Fixed Access Platforms
Fixed access platforms are permanently installed structures tied into the building, steelwork, or foundations. They don’t move and are engineered for long-term service in a defined location. Fixed platforms make sense when:
The access need is permanent and clearly defined (e.g., top of a tank, a mezzanine, or a fixed conveyor)
Loads are high or frequent, and continuous anchoring is required
Integration with existing building structure or process equipment is critical
The site must satisfy specific code or insurer requirements for permanent access
Northern Platforms has extensive experience building permanent loading platforms for a variety of applications. For further details about these projects, contact our office.

Portable stairs are one of those pieces of equipment that look simple from the outside but come in more configurations than most buyers expect. The right choice depends on what you’re accessing, how often you’re accessing it, whether the stairs need to move around the site, and what height variability you’re dealing with. This guide covers the four main types of portable stairs Northern Platforms carries, what each one is built for, and how to decide which is right for your application.
Type 1: Fixed Portable Stairs
Fixed portable stairs are prefabricated stair units designed for a set height range — typically used to provide access to a specific entry point, elevated surface, or piece of equipment that doesn’t change. Despite the name, they’re portable in the sense that they can be relocated when needed, but they’re generally positioned and left in place for extended use.
What they’re built for: Trailer and modular building access, elevated platform entry, roof access hatches, construction site office stairs, and any application where a permanent concrete or wood stair isn’t warranted but a stable, compliant access point is needed in one location.
Key specs to look for:
Height range matching your specific application (ErectaStep fixed portable stairs are available in 7 sizes from 28″ to 63″)
IBC, OSHA, and OH&S-compliant construction
Field-adjustable legs for uneven surfaces — essential for outdoor and construction site applications
Slip-resistant tread surface
Platform size adequate for the entry point (4×6′ and 4×4′ platforms available)
Entry configurations: direct, left, right, or multiple entry; double stair options for high-traffic access points
When it’s the right choice: You need a compliant, stable stair at a fixed location and don’t want to build or pour concrete. For temporary site trailers, construction phase access, or any elevated entry that needs to meet code without a permanent structure.
Type 2: Tilt-and-Roll Portable Stairs
Tilt-and-roll stairs are mobile stair units that can be tilted back on integrated rear wheels to move from one location to another, then set down flat for stable use. A single operator can reposition them without equipment or assistance.
What they’re built for: Warehouses, manufacturing facilities, and distribution centres where workers need to access shelving, mezzanines, or equipment at different points throughout a shift. Anywhere that a stair needs to serve multiple locations on the same floor.
Key specs to look for:
Wheel size and material — larger wheels handle uneven or outdoor surfaces better
Load rating on both the platform and the steps
Handrail configuration — full-height handrails on both sides for industrial applications
Locking mechanism when stationary — caster locks should engage quickly and hold firmly
Step width adequate for carrying tools or equipment while ascending
When it’s the right choice: Your workers need stair access at multiple points in a facility, and repositioning needs to be fast and single-operator. A fixed stair at every location isn’t practical; a tilt-and-roll unit serves the whole area.
Type 3: Rolling Self-Levelling Stairs
Rolling self-levelling stairs take mobility a step further. These units are designed to be repositioned frequently and adjust their platform height to match varying access heights — so the same unit can serve different pieces of equipment or vehicles without reconfiguration. The RollaStep G Series is the leading example of this type: a variable-height, self-levelling stair and platform with gas spring height adjustment and a locking pin to secure the set height.
What they’re built for: Process facilities, tank farms, refineries, and maintenance operations where workers access equipment at multiple heights throughout the day. Loading areas where vehicle or equipment heights vary. Any application where a single stair unit needs to replace multiple fixed-height platforms.
Key specs to look for:
Height adjustment range — the RollaStep G Series adjusts to accommodate a wide range of access heights
Self-levelling step and platform mechanism — steps should automatically level at every height setting, not require manual adjustment
Platform load rating — the G Series carries a 300 lb platform load limit
Caster quality — 360° locking casters with no-flat construction for outdoor and uneven surfaces
Platform size — the G Series provides a 6 square foot work surface, accommodating an operator with tools
Non-slip tread — self-draining, aggressive tread for wet and cold weather conditions
When it’s the right choice: You’re dealing with variable access heights across your site and want one unit that handles all of them. Particularly valuable in oil and gas, chemical processing, and maintenance environments where equipment heights vary, and workers move through multiple tasks in a shift.
Type 4: Cantilever Rolling Stairs
Cantilever rolling stairs are the most specialized type of portable stair — designed for applications where the access point is above or beyond an obstacle that prevents a standard stair from getting close enough. The platform extends out beyond the base of the unit, allowing workers to get above piping, containment walls, tank berms, or vehicle rooflines without the stair base contacting the obstacle or the equipment being serviced.
The RollaStep C Series is the industry standard for this type: a counterweighted cantilever platform that extends 2’5″ beyond the base, with 360° locking swivel casters that allow precise placement around sensitive equipment.
What they’re built for: Tank truck and railcar loading and unloading access, tank hatch access in process facilities, equipment access where piping or containment prevents direct approach, and chemical or petroleum handling environments where contact with the equipment must be avoided.
Key specs to look for:
Cantilever extension length — must reach far enough to position the operator above the access point
Counterweight design — a properly counterweighted unit should be stable with an operator on the platform without tipping
Caster locking — must lock securely before any operator climbs; look for total-lock casters that lock both rotation and swivel
Platform and handrail configuration — full handrails, adequate platform depth for working with equipment or hoses
OSHA compliance — non-negotiable for any industrial application
When it’s the right choice: You’re loading or unloading tank trucks or railcars, accessing tank hatches, or working above or around any obstacle that prevents a standard stair from approaching directly. This is the unit that replaces the improvised ladder-over-the-berm solution that no one should be using.
