What colors must all hoistway entrance bars and gates be painted with?

All hoistway entrance bars and gates must be painted with diagonal contrasting colors to ensure visibility and safety. The use of contrasting colors allows for clear differentiation between the entrance and the surrounding material, making it easier for individuals to recognize the opening and understand the presence of an elevator or hoistway. The diagonal pattern is particularly effective in catching the attention of individuals, reducing the likelihood of accidents by creating a visual warning. This practice serves to enhance safety measures within buildings where elevator access is present, ensuring that people are alert to changes in elevation and movement.
