Employers are responsible for making decisions about the details of emergency medical care in their workplaces, depending upon the size of the workplace, the kinds of hazards present, the history of accidents, and the costs of various options. The federal Occupational Safety and Health Act (OSH Act), which governs Colorado workplace safety and health in the private (businesses and nonprofit organizations) sector, requires every employer to ensure that medical personnel are readily available for advice and consultation and that when an infirmary, clinic, or hospital is not within close proximity to the workplace, there is at least one individual who is adequately trained to administer first aid (29 CFR 1910.151).
There are no state laws or regulations that govern workplace safety and health in the public sector (state and local offices and operations, school systems, commissions, etc.) in Colorado. Therefore, there are no first-aid requirements for public sector workplaces, except those that may be required under county or municipal codes.
