- Removing a patient from a simulated trench collapse during a training exercise in Sierra Vista, Arizona. This class was held for the Sierra Vista Fire Department in 2012.
Specifically, students will learn:
- Basic soil mechanics and trench failure patterns.
- General requirements for working safely below ground.
- Scene assessment and control.
- Constructing safe zones in the trench.
- Patient packaging and extrication.
There are various levels of training that D2000 Safety can provide. These training levels correspond to the NFPA guidelines (1670) and include:
Trench Rescue Operations: Teams operating at the operations level can perform rescues from non-intersecting trenches less than about eight-feet deep. In addition there are no severe environmental hazards present. This level of training requires about three days.
Trench Rescue Technician: Teams operating at this level can perform extrications from deeper trenches that may include intersections, T’s and bends. There may be severe environmental hazards present such as hazardous atmospheres. This level of training requires five days.
