Railway Safety Act, FRA Rules and 49 CFR Part 227 Subpart C: EEBA Requirements for Freight Rail Operators

For rail safety teams, the wider conversation around the Railway Safety Act is important. But when it comes to emergency escape breathing apparatus, the most relevant Federal Railroad Administration regulation is more specific: 49 CFR Part 227, Subpart C.

This is the FRA regulation that sets out Emergency Escape Breathing Apparatus Standards for certain freight rail operations. It is particularly relevant to railroads transporting hazardous materials that could create an inhalation hazard if released during an accident.

For operators reviewing their safety equipment needs, the rule raises practical questions. Who needs access to emergency escape breathing apparatus? What type of equipment should be selected? How should it be stored, inspected and maintained? And how can operators source equipment that supports their planning?

Carroll Technologies Group supports railroad operators with safety equipment for demanding rail environments, including the Ocenco M-20.2 Rescuer Breathing Device, gas detection equipment, communications equipment, PPE, lighting and other rail safety products.

What is the Railway Safety Act?

The Railway Safety Act is proposed federal legislation focused on strengthening rail safety in the United States. It was reintroduced in 2026 following the Norfolk Southern derailment in East Palestine, Ohio and is intended to address wider rail safety concerns including freight rail oversight, hazardous materials, emergency response, inspections and penalties.

The Railway Safety Act is not the same thing as the FRA EEBA regulation. It is a broader legislative proposal, while 49 CFR Part 227, Subpart C is the specific regulation rail operators should review when looking at emergency escape breathing apparatus requirements.

However, the two are connected by the same wider issue: how railroads prepare for high-risk operating environments, particularly when hazardous materials are involved.

What does the Federal Railroad Administration do?

The Federal Railroad Administration (FRA), is part of the US Department of Transportation. Its Office of Railroad Safety promotes and regulates safety across the nation’s railroad industry, including compliance and enforcement in areas such as hazardous materials, motive power and equipment, operating practices, signal and train control, grade crossings and track.

For rail operators, FRA rules are central to safety planning. They define requirements across different areas of railroad operations and provide the regulatory framework that operators must use when reviewing equipment, training, maintenance and recordkeeping obligations.

In the case of emergency breathing equipment, the key FRA regulation is 49 CFR Part 227, Subpart C.

What is 49 CFR Part 227, Subpart C?

49 CFR Part 227, Subpart C is the Federal Railroad Administration regulation covering Emergency Escape Breathing Apparatus Standards.

The rule applies to certain freight rail operations involving PIH materials, which are materials that are poisonous by inhalation. In plain terms, the regulation is concerned with protecting covered rail employees who may be in a locomotive cab if a hazardous material release creates an inhalation hazard.

The FRA’s 2024 final rule amended 49 CFR Part 227 to require freight railroads to provide covered employees with appropriate atmosphere-supplying emergency escape breathing apparatus when occupying the locomotive cab of a train transporting hazardous materials that would pose an inhalation hazard if released during an accident.

The rule also requires railroads to establish programmes covering the selection, procurement and provision of EEBAs, as well as inspection, maintenance, replacement and employee instruction.

Who does the FRA EEBA rule apply to?

Under 49 CFR Part 227, Subpart C, the requirement is focused on covered employees in the locomotive cab of an in-service freight train transporting PIH materials.

The rule identifies covered employees as including train employees, direct supervisors of train employees, deadheading employees and other employees designated by the railroad in writing.

The regulation is not a general requirement for every rail employee in every rail environment. It is specific to the circumstances set out in the rule, particularly locomotive-cab occupancy on freight trains transporting PIH materials.

Rail operators should review the full regulation and seek appropriate compliance advice when determining how the rule applies to their operations.

What does 49 CFR Part 227, Subpart C require?

The regulation covers several practical areas of EEBA planning.

Railroads must select an atmosphere-supplying EEBA that protects against the PIH materials being transported. The equipment must meet recognised criteria, including requirements around minimum breathing capacity and accepted standards.

The rule also covers storage. EEBAs must be stored in a way that protects the equipment from damage, contamination, dust, sunlight, extreme temperatures, moisture and chemicals. Storage must also allow subject employees to access the EEBA during an emergency and locate it in adverse conditions, such as darkness or disorientation.

Inspection, maintenance and replacement are also part of the regulation. Railroads must establish and comply with written procedures for inspecting, maintaining and replacing required EEBAs. This includes pre-trip inspection procedures, periodic inspection and maintenance in line with manufacturer recommendations and procedures for replacing defective, failed or used equipment.

Employee instruction is another key part of the rule. Railroads must provide instruction on the purpose, limitations, use, inspection, storage and maintenance of EEBAs.

Why does EEBA selection matter?

EEBA selection is one of the most commercially important parts of the regulation for rail safety teams.

The equipment must be suitable for the materials being transported and the escape purpose it is intended to support. Under the rule, each EEBA must be fully charged and contain a minimum breathing capacity of 15 minutes at the time of the required pre-trip inspection.

The regulation also recognises standards including ISO 23269-1:2008, BS EN 13794:2002 and BS EN 1146:2005, as well as NIOSH certification for escape-only respirators under the relevant criteria.

For rail operators, this means EEBA procurement is not simply about buying any emergency breathing device. The product selected needs to be reviewed against the FRA requirements, the materials being transported, the operating environment and the railroad’s internal safety procedures.

Ocenco M-20.2 Rescuer Breathing Device for railroad EEBA planning

Carroll Technologies Group supplies the Ocenco M-20.2 Rescuer Breathing Device, a self-contained, closed-circuit breathing apparatus designed to support emergency escape from toxic or oxygen-deficient atmospheres.

The Ocenco M-20.2 has a 15-minute performance duration, a donning time of less than 10 seconds and ISO 23269-1:2008 approval. These product characteristics make it a relevant option for rail operators reviewing EEBA needs in light of 49 CFR Part 227, Subpart C.

Rail operators can view the Ocenco M-20.2 Rescuer Breathing Device through Carroll Technologies Group’s online store.

Planning for rail safety beyond the Railway Safety Act

The Railway Safety Act has helped bring rail safety, hazardous materials and emergency response back into focus. But for operators looking at specific equipment requirements, the most important next step is understanding the regulations that already apply to their operations.

For EEBA planning, that means reviewing 49 CFR Part 227, Subpart C, understanding how the Federal Railroad Administration rule applies and identifying suitable emergency escape breathing apparatus for covered employees.

Carroll Technologies Group can help railroad operators source relevant rail safety equipment, including the Ocenco M-20.2 Rescuer Breathing Device, as part of a wider approach to emergency preparedness and worker safety.
