Final answer:
Per OSHA, this situation requires the employer to provide a safe workplace, follow safety standards, and address hazards.
Step-by-step explanation:
Per the Occupational Safety and Health Act (OSHA), if Drake slips, falls, and injures his back while cleaning the back access road, his employer is responsible for providing a safe workplace and must follow OSHA safety and health standards.
In this situation, Drake's employer would be required to have fall protection measures in place, such as safety harnesses or guardrails, to prevent accidents like slipping and falling. They should also have a system to address hazards and find feasible ways to eliminate or reduce risks in the workplace.
Drake and his colleagues have the right to receive safety training, be informed about hazards on the job, and file a complaint with OSHA if they believe there is a serious hazard or if their employer is not following OSHA standards.
