Zistos remote video inspection tools can increase safety and reduce costs for maintenance/repair operations in a confined space.


The first stage of any maintenance repair operation is a visual assessment of equipment and conditions. There are many instances where these maintenance and repair operations involve equipment and environments that are within a confined space. Confined space entry can be dangerous and there are regulations and safety mandates in place that do increase the safety. These regulations improve confined space safety, but they can also increase the cost and complexity of the confined space entry operation. By using remote video inspection tools from Zistos Corporation, the number of confined space entries can be reduced and in some cases eliminated entirely. By utilizing these tools it is possible to both increase the safety of the confined space entry operation, while at the same time reduce the overall costs to facilitate the maintenance operation.

Dangers of Confined Space Entry

A space is generally recognized to be a “Confined Space” if it:

  • has limited or restricted means of entry or exit;
  • is large enough for a person to enter to perform tasks;
  • is not designed or configured for continuous occupancy;
  • has the potential for a significant hazard to be present.

Confined spaces are inherently dangerous and unfortunately, many confined space industrial accidents have resulted in the death and injury of workers.

As a result of these dangers, OSHA has strict regulations and procedures that must be followed when an individual must make a confined space entry. The implementation of these procedures does increase confined space safety, but they do require additional manpower, equipment, training and administrative considerations.

The First Step of a Maintenance/Repair Operation

In almost every instance, maintenance and repair operations start out by making a visual assessment of operating conditions, environment and equipment. This allows the process to move forward with the knowledge of what, if any, problems exist and how to try to remedy the condition.

The Capabilities and Benefits of Remote Video Inspection

A remote video inspection tool such as the Industrial Zoom Pole Camera from Zistos Corporation, allows the worker to make this visual assessment safely outside of the confined space – without the need for entry. The camera system allows the operator to insert the camera into the confined space envelope and view/record the area and equipment for problems using a variety of different camera technologies, such as zoom, low light and even thermal imaging.

This required first step involving a visual assessment of conditions can be completed outside of the confined space. This has the benefit of increasing the safety and reducing the complexity and cost of the operation. It not only alerts the worker to the status of equipment/environment in the space, it also increases awareness of any hazards that may be present in the confined space prior to entry. If upon completion of the inspection phase it is determined that there are no obvious problems that require attention, the worker does not even need to enter the space.

Cost Analysis

In one application a cost analysis conducted on the use of this video inspection tool had a complete return on investment after less than 40 hours of use. This analysis did not even factor in any consideration to reduction of on the job injury or disability claims from confined space accidents.


The benefits of using a remote inspection tool such as the Zistos video inspection product to keep workers out of confined or dangerous spaces makes sense on every level. The tools facilitate the sound practice of exposing a worker to a potentially hazardous environment only when the need for and safety of entry are confirmed following a visual assessment. The use of this approach benefits both the bottom line of an operation and helps insure the safety and well-being of the primary asset of any industrial concern – their employees.
