Almost every employer needs a formal “Work Alone†policy that:
1) Defines which tasks are not suitable for working alone. OSHA prohibits working alone in at least nine OSHA general industry standards.
2) Defines steps to take — such as communication systems required, or reporting in periodically, or having someone check on the employee periodically — when employees are allowed to work alone on highly hazardous jobs such as working with corrosive chemicals, high voltage, or testing and positioning of machinery.
3) Establishes other controls such as emergency signaling and emergency response and rescue.
In one case, an employee was injured while working alone in a far corner of the warehouse cleaning up the area for about four hours. He was exposed to moving machinery, electrical equipment, harsh chemicals, excessive noise, heat, and vermin such as spiders. In addition, we learned that this employee has hearing loss and could not hear the emergency alarm if it had sounded.
In another example, a park ranger in a national park in the western U.S. was hurt while repairing the walkway through an area of the park. He was exposed to electrical tools, running water, excessive heat (about 95 degrees that day), and heavy lifting. He was a mile or so from the ranger station without a working partner. Occasionally, a hiker would walk by, but on this hot day, that seldom happened.
These examples show the need for communication devices, another co-worker, or having someone check on employees periodically.

But most fixed site jobs in factories, warehouses, and buildings expose employees to hazards when there may not be other people around. When this is the case, a plan (or “Work Alone†policy) should be followed. This plan should include consideration of such steps as:

I assisted one of my clients in developing a “Work Alone†policy several years ago after one of their foresters did not return to the camp one day after being in the forest by himself. No one missed him until the next day when he did not show up for work because he lived alone. After checking with relatives and his favorite watering holes, a search team was sent out. Several days later the search team found the worker’s body; he had suffered a stroke while in the woods. Perhaps nothing could have been done for him, but if he had carried a communication device or other provisions had been made to account for him, the outcome may have been different.
