The Purple Line’s location on University of Maryland’s campus introduces unique safety risks for anyone working in or around the construction and operations corridor. In addition to standard jobsite hazards, proximity to an active light rail system and its overhead catenary wires creates elevated risks related to electrical exposure, equipment movement, and restricted right-of-way access.
If you or your team will be working within 25 feet of the nearest Purple Line rail, whether you’re performing maintenance, construction, inspections, landscaping, or general campus operations. It is essential to understand the precautions required in this environment. Please review the training modules below to determine which apply to your specific tasks and ensure all personnel are properly prepared before beginning work.

The following topics below can be used in developing your "Site Specific Work Safety Plan."
Electrical Safety
Working near a light-rail system with overhead catenary wires means there is a high risk of electrical hazards. Training in electrical safety is essential to ensure workers understand how to recognize and avoid contact with live electrical systems, follow safe practices, use appropriate PPE, and coordinate with power shutdowns or isolation procedures.
Fall Protection
Working near the Purple Line may require activities like accessing equipment on ladders or maintaining infrastructure near catenary wires, which introduces a heightened risk of falls.
Hand Protection
Workers performing tasks near the Purple Line may encounter sharp edges, high-heat surfaces, electrical components and other hazards that could result in cuts, punctures, burns, or skin irritation.
Lockout/Tagout
Even when the overhead wires or rail electrification are normally live, maintenance or work near them often requires shutting down or isolating energy sources. Ensuring workers understand lockout/tagout procedures is critical in the context of catenary wires and rail systems.
Trenching and Shoring
Purple-line adjacent work may involve excavation to access utilities or other infrastructure, exposing workers to exposures such as cave-ins, falling loads, underground utilities, and other hazardous atmospheres.

Personal Protective Equipment (PPE)
Tasks near the purple line may expose workers to hazards such as moving equipment, energized systems, sharp objects, noise, dust, chemicals, and so on. Training is especially important for workers to identify the type and limitations that PPE may provide. Certain types of PPE may be required based on the work taking place in the vicinity of the Purple Line.
Hearing Conservation
Routine light rail operations can generate noise levels high enough to damage hearing over time. Workers may be exposed to short, intense bursts of noise or sustained elevated sounds without realizing the risk.
