Colorado’s diverse economy spans sectors from agriculture and mining to healthcare, retail, and energy—many of which involve employees working alone in the field, at remote sites, or during off-hours. These “lone workers” face increased risks due to their isolation. While Colorado does not operate its own OSHA-approved occupational safety and health plan, employers are still required to meet federal OSHA standards.
This guide outlines how lone worker safety is managed in Colorado and what employers can do to ensure their teams stay safe and compliant.
As a federal OSHA state, Colorado follows regulations set by the Occupational Safety and Health Administration rather than enforcing its own workplace safety laws. OSHA does not have a regulation specific to lone workers, but various standards and general duty requirements still apply. For example, employers must assess job-related hazards and ensure employees have the training, tools, and procedures necessary to perform their jobs safely, even when working alone.
This is especially relevant in Colorado, where employees often work in remote areas, extreme weather conditions, or high-risk settings like oil and gas fields or mountain terrain. OSHA’s General Duty Clause (Section 5(a)(1)) requires employers to provide a workplace free from recognized hazards that are likely to cause serious harm. This duty includes evaluating the additional risks that arise when workers are isolated from others.
There is no official definition of a “lone worker” in Colorado legislation. However, the concept is widely recognized in occupational health and safety circles. A lone worker is typically defined as someone who performs duties without close or direct supervision and cannot be readily seen, heard, or assisted by coworkers.
Lone workers in Colorado can be found in a wide range of environments, including:
In these scenarios, employees may face increased delays in receiving help during emergencies or incidents, which places a greater burden on employers to plan for and mitigate those risks.
Employers in Colorado must meet federal OSHA requirements when managing employees who work alone. This includes identifying risks specific to working in isolation and implementing procedures to protect lone workers from injury, illness, or other workplace hazards.
Recommended steps include:
Employers should also take into account weather-related hazards, especially in Colorado’s mountainous or high-altitude areas, where help may be delayed due to location or travel conditions.

The Safe Lone Worker app offers a practical solution for employers looking to enhance safety for isolated employees. Its features—including GPS tracking, automatic fall detection, panic button alerts, and timed check-ins—can significantly reduce response time during emergencies and help meet OSHA’s general safety requirements.
Given Colorado’s varied terrain and sometimes unpredictable weather, technology that ensures real-time monitoring and communication is especially valuable. These digital tools also help employers demonstrate due diligence and maintain records of safety compliance for audit or legal purposes.
Colorado does not administer its own state-run occupational safety program, meaning all workplace safety regulations are governed by federal OSHA. As such, there are no state-specific laws that directly address lone workers. However, employers are still fully responsible for ensuring that any employee working alone is protected under OSHA’s broader health and safety framework.
Colorado employers are encouraged to consult federal OSHA guidelines and, when applicable, coordinate with industry associations or safety consultants to stay current on best practices for lone worker safety.
