Proper Use of Your Skedco Tripod

Tuesday, July 27, 2010

Recently, we had a client ask about these specific uses of the Sked-EVAC tripod. Here’s what the manufacturer (Skedco) had to say…

“Is it safe to attach a ‘change of direction’ onto the lower end of one of the tripod legs?”

“No!” According to Bud Calkin, the manufacturer of the tripod. He continues in saying that it is unsafe to pull horizonally on one leg of any tripod because it may cause the tripod to shift and destabilize the system. Skedco recommends the use of a separate anchor in this case.

“Is it acceptable to use the tripod as an ‘A’ frame and lean it over the edge?”

Yes, if you rotate the tripod feet so that the pointed ends of the feet are down and supporting the tripod. According to Skedco, if you are working on a surface that would allow the feet to slip, you must tie or secure the feet in such a manner that they cannot slip and allow the system to collapse.

By using any tripod that has swiveling feet in that configuration (bipod) with the feet flat on a hard surface, you will experience uneven pressure on the edges of the feet as it is leaned over the edge. This could possibly damage the feet because of the angle at which they are turned (i.e., the feet are pointed toward the center of the triangle formed by the tripod). This angle places the weight of the tripod onto the edges of the feet and that is not what they are designed for.

Skedco also says that when using the Sked-Evac tripod as an “A” frame, it is necessary to attach ropes to the two unused anchors that are attached to the head. You can do this by using carabiners. Tie the tripod back in the opposite direction from the load that is being hoisted. This will prevent the tripod from leaning too far over the edge and causing the system to collapse. Check all rigging and attachments for safety prior to lifting any load, especially a human load.

The improper use of any tripod is very dangerous and could be fatal. It is the responsibility of the user to get proper training prior to using a tripod or any other rescue equipment.

Can a munter hitch be used with a two-person load?

Thursday, July 01, 2010

Yes, with a couple of extra precautions.

    •    The rope should run over an edge for extra control.

Does the confined space entrant need to use a harness and lifeline or retrieval system even when a trained rescue team is on site?

Wednesday, June 09, 2010

Yes. A retrieval system should be used whenever an entrant enters a permit space, unless the retrieval system creates a greater hazard to the entrant or does not contribute to the rescue effort.

When considering proper patient packaging, is the patient’s medical condition the only priority?

Wednesday, June 09, 2010

No. The rescuer should also consider the size and configuration of the confined space (i.e., once packaged, will the patient and packaging fit through the opening?) as well as the rescue techniques to be used, the atmosphere inside the space and the exposure to hazards.
