HAZWOPER Question… Does a person who will ONLY participate in Decon be required to have Operations or Tech level training?

Scenario Facts:

1. These workers would NEVER enter the warm or hot zone for defensive or offensive actionsrelated to controlling the uncontrolled release.  They will be in the warm zone as they will be participating in Decon, but this places them in the far edge of the Warm Zone (e.g. right at the Cold Zone line). 
2. They are trained in HAZCOM of the chemicals involved in the uncontrolled release and the Decon chemicals. 
3. They are trained in the PPE they will be using. 
4. They are trained in the Decon Procedure which resides in the emergency response plan and all the equipment associated with the Decon procedure(s).

Will their regular safety training on these items make them “compliant” with 1910.120(q)?
