If a Health and Safety Representative is required on your site, you are legally obligated to identify the rep by name, trade, and employer. IHSA provides an 17” x 22” poster to identify the Health and Safety Rep on site. This poster is printed on weather-resistant polystyrene. Holes located in each corner will give you more options to display it around the jobsite (e.g., affixing it to chain-link fences).
