What confined-space rescue protocol (internal, third party, etc.) have you developed, and why did you choose this plan?

We deal with confined spaces on occasion, but most of the ones we're dealing with are trenches or excavations. I've had jobs where it was a fair bit on the nasty side (underground tanks bedded in a former coal bunker using fly ash with asbestos-wrapped pipe overhead and a very small access hole), so we used third party to make sure we didn't forget anything and due to the rescue aspects. Others times, we've done it internally as it was more akin to what we normally do (excavation), and the overall planning was more straight forward (just the basics for ingress/egress, atmospheric testing / protection and emergency events). The latter case was far more straight forward, and it played into our decision to go internal. Overall, though, unless it is a regular occurrence and you're comfortable with the circumstances, bring in a third party for the assistance.

I can think of fewer more dangerous tasks than cutting open a UST and climbing inside to blast and coat it. We were so advanced at the time that local fire departments would come to our sites to ask us best methods for confined-space entry and rescue. Without writing a lengthy article on the topic, which rescue protocol you choose should depend on the frequency of your entry into confined spaces. If you do it only rarely, you will likely not acquire the skill to do it successfully on a regular basis. You may also not keep your equipment up to date, if you're not using it often. If you enter often, then it's best to develop your own program, and keep your equipment up to date and people highly trained. If this is a routine task, internal is best; if it's non-routine, it would be better to have a third party on-site for supervision and assistance..
