Weathered Trefoil Warning Symbols in a Grid

Rows of biohazard warning symbols create a striking pattern across different colored backgrounds. Each trefoil emblem appears on yellow, red, green, and black panels with varying textures and wear patterns. Some symbols look freshly painted while others show signs of rust and weathering. The three-dimensional effect makes the hazard signs pop against their vibrant backgrounds, creating an industrial warning aesthetic. The organized grid arrangement showcases the iconic radiation warning design in different states of preservation, from pristine to heavily corroded.
