What is necessary when using structural ramps in lieu of steps?

When utilizing structural ramps instead of steps, incorporating cleats or surface treatments for slip prevention is essential. Ramps can become slippery, especially in wet or icy conditions, which poses a significant hazard. Cleats or other surface treatments improve traction and help ensure that individuals using the ramp can move safely without the risk of slipping.

Considering other options, while no extra measures might seem convenient, it overlooks the safety risks associated with using ramps. Railings on both sides can enhance safety but are not universally required, depending on the ramp's height and design. Wide ramps are beneficial for equipment accessibility, but they don't specifically address the concern of slipping, which is critical when ensuring a safe passage. Thus, slip prevention is the primary factor that elevates the necessity of cleats or surface treatments on ramps.
