The Occupational Safety and Health Act (OSHA) requires employers to run a business free from recognized hazards. OSHA provides comprehensive regulation pertaining to handling of hazardous materials, working under dangerous conditions, and operating all types of equipment.
Just because the jobs you manage are performed in an office setting and not a plant does not make your department exempt from OSHA requirements. For example does your company have an Emergency Action Plan in the event of a fire? How would you and your workers escape the building in such a situation? Work with HR or the Safety function to provide a safe work environment for your employees.
