Final answer:
The name, address, and phone number of a medical care facility should be posted in the employer's office and might also need to be posted in the service vehicle, depending on specific regulations.
Step-by-step explanation:
The information regarding the name, address, and phone number of a medical care facility that relates to an employer's office or service vehicle is crucial for safety and compliance with regulations. Although the prompt provided does not directly answer the student's question, generally, this information must be easily accessible to employees; therefore, it needs to be posted in the employer's office and sometimes also posted in the service vehicle, depending on the specific regulations applicable.
For some industries or jobs, especially those involving hazardous materials or situations, regulations might require that the information is posted in both locations to ensure that employees have access to it in case of an emergency. Memorizing this information can be helpful as well, but it is not a substitute for having it visibly posted where it is needed.
