After describing how the CSE SCSR works, this segment explains the donning procedure with step-by-step demonstrations in both emergency and classroom settings. It stresses the importance of following instructions, keeping calm, and understanding the normal rises in temperature and breathing resistance that occur with the CSE SCSR during use. (09:05)

The time it takes to escape may exceed the duration of the SCSR you first donned in an emergency. If it does, you'll need to change over to a spare unit while the surrounding air is still unsafe to breathe. This segment explains when to change over, and demonstrates the steps for doing it smoothly and safely. (04:49)

Occasionally, under stress, a user disables his or her SCSR by letting vital starter oxygen escape from the mouthpiece while donning. If no backup SCSR is handy, there is still a Plan B- starting the SCSR with lungpower alone. By watching this segment, you'll learn how to perform a manual start, resume donning, and head for safety.

Mine operators must inspect every SCSR four times a year. This segment demonstrates each step in the 90-day inspection process, including visual inspection, field-testing with the CSE acoustic solids movement detector (ASMD), and checking the ASMD's calibration by using the CSE Spot Checker. Applies to both the ASR and SRLD models. (13:15)

Users must inspect their own SCSRs before every shift. This segment shows what to look for, and when to turn an SCSR in for a replacement: how to inspect the carrying pouch, moisture and temperature indicators, and date of manufacture; and how to evaluate external damage. (07:19)

This segment demonstrates CSE SCSR donning practice with the CSE SR-D. The SR-D also offers expectation training for the rise in breathing resistance that normally accompanies SCSR operation, as well as for the fit of the mouthpiece and the size and shape of the SCSR in use. Applies to the SRLD and ASR models. (05:00)

If an SCSR user loses the unit's starter oxygen through the mouthpiece before it can inflate the breathing bag, manually starting the unit can be a life-saving skill. This segment shows how to practice the manual start using the CSE SR-T, which also demonstrates the range of temperature and breathing resistance of an actual SCSR. Applies to all CSE SCSR models. (06:14)

With step-by-step instructions, this segment shows how to conduct expectation training using the CSE SR-MP. Trainees will experience the fit of the mouthpiece and the breathing resistance and heat that build up toward the end of a CSE SCSR's operating duration. Applies to all CSE SCSR models. (03:31)
