- Report results to mine operators, MSHA and Manufacturers
- Liaison with stakeholders on testing issues
Milestones
- Improved sampling methodology for the LTFE
- Improved LTFE sample handling and recording
- Indentified problem with inspection of field deployed units
- Identified problems with inspection criteria in user instructions
- Identified potential problem with low O2 in the presence of very low O2 in the breathing circuit. Projected)

Outputs
- Draft LTR1 report is in initial review process 93/2/2011)
- 3 CPIP have been opened. One model has been removed from production and an improved model submitted for approval in its place
- A major investigation of the reliability of one model of SCSR is currently underway. This is an comprehensive evaluation of the mine workers risk of using that device
- MSHA and NIOSH have modified their position on manually starting dry chemical bed O2 devices
Outcomes
- Validation that equipment is performing as certified
- Corrective actions by manufacturers to address reported problems
- NPPTL, PRL, and MSHA developed new O2 protocol
