If leak is verified to be vapor only, per flight rules, contamination is only suspected. MCC will direct crew to perform blocks 7,8,10, then repress followed by blocks 12 through 15.

2

Bakeout should be performed for the remainder of orbit day.

3

During orbit night, the EMU should be in the Crewlock which is a warm environment. This raises the surface temperature of the EMU which increases the sublimation of the contaminant. Block 10 should be done only if more than 10 minutes of orbit night remain.

During EVA, When Crew Visually Detects Plume, White Crystals, or “Snow” Coming From Orbiter/Station.

When Orbiter/Station Chemical System Leak Suspected Due to Steady (not Step Function) Decrease in Pressure or Temperature.

DCS TREATMENT (ISS EVA/7A - ALL/BAS) Page 1 of 4 pages

1

EVA terminated to prevent progression to Cuff Class 4. If Cuff 2, affected crewmember will assist other EV with minor worksite cleanup, if possible, to expedite cleanup and then terminate EVA.

2

If estimated time reqd for DCS treatment exceeds Metox canister consumables, a changeout should be performed. If 10 or 12 reqd, minimum treatment is ~3 hr.

3

For Cuff Class 3 only, affected crewmember waiting in Crewlock needs to be in contact with Surgeon via PMC due to severity and potential progression of symptoms.

4

Cuff Class 4 symptoms may be secondary to Type 2 DCS which is a medical emergency. Unstowing the resuscitator enables IV crew to be prepared to administer CPR, if reqd. Because it is critical to repress a Class 4 quickly, this may result in a one crewmember repress.

DCS Signs and Symptoms Associated with Each Cuff Class Defined in Cuff C/L

1

• Determine Cuff Class Cuff Class 1

Cuff Class 2 or 3 (Report to MCC-H)

Cuff Class 4 (Report to MCC-H)

• Report to Surgeon next PMC.

• Terminate EVA (Cuff C/L, 7).

• Unaffected crewmember stow safety tether, perform worksite cleanup and/or ISS safing.
