Working alone in Arizona
A starting point for mining safety and working alone.
Authority and scope
Mining safety and working alone
Arizona mining rules address working alone where hazardous conditions could endanger a worker. Rule R11-1-143 requires that the worker be able to communicate with others, be heard or be seen. For underground mines, R11-1-144 also requires a check-in and check-out system and a surface record of people in the mine. Review the requirements for the operation, including applicable federal mining rules.
This is one starting point for the work described, not a complete list of state or federal requirements. Check which agency and rules apply to the employer and task.

Questions for your plan
What communication, staffing and underground accountability arrangements are required for the specific mining operation?
What to review
Review the mine, task and applicable rules, including communication or visual or audible contact, underground accountability, and emergency arrangements. A monitoring service does not replace required mine procedures or equipment.
Some work requires another person on site. Remote monitoring does not replace that requirement or the organization's own assessment, training and emergency procedures.
