Workplace overcrowding rules require safe space, hazard signs, separated pathways, and controlled vehicle movement. Employers must prevent overcrowding in workplaces by ensuring that floor space, dock areas, machinery placement, and material storage do not create danger to employees. Sufficient space must be provided around machines for normal operation, repairs, and handling of materials, and adequate safeguards must be used to prevent overcrowding where employees work or assemble. These safeguards include warning signs, separation of vehicle and pedestrian routes, and effective vehicle management, subject to limited exceptions for certain categories of work.
