Isometric Stairway Model with Safety Color-Coding System

This drawing depicts a standard five-step stairway in isometric projection, featuring a safety color-coding system with bright yellow tread nosings against white treads, complemented by a red sidewall. This model uses a simple but effective representation technique with 95 entities (42 lines and 53 solids) to create a 3D visualization. Each step maintains consistent rise and run dimensions in accordance with typical accessibility standards. The yellow nosing highlights conform to OSHA visibility requirements for stair edge demarcation in public spaces, providing both visual contrast and slip hazard awareness. The compact design with approximately 87mm width and 100mm height (as per the metadata) makes this suitable for integration into various architectural presentations or safety documentation packages. The minimalist representation effectively communicates essential safety features without unnecessary detail.
