Before an excavation or construction company begins work that takes place on a slope, professionals must make sure that they follow certain guidelines provided by federal law. The Occupational Safety and Health Administration (OSHA) provides guidelines that every business must follow in order to promote a safe workplace for employees. OSHA slope regulations are aimed at protecting laborers from cave-ins, exposure to harmful substances and inhalation of dangerous fumes. The regulations also require companies to provide certain types of safety equipment and gear to workers.
