Wondering where everyone stands on Hot /Cold Tapping?

Does your team perform Hot or Cold Tapps?

If Yes:
What did your training consist of (length, content, etc)?
What type of equipment are your using?
What are your policies / procedures?

If No:
Do you have a contractor / resource that you plan to call in the event you need to tapp?

Also do your view Hot / Cold Tapping as the repsonsability of Emergency Responders or a Specialized Response Agency?

Thanks,
