Task NO.: SEAM Proposal Request

TASK TITLE: Emergency Mask Trainers

REQUIREMENTS/REFERENCES:

1. Reverse engineer and build 10 ea. Emergency Mask trainers from provided documentation and photos.

1.1 Hardware Overview

The Emergency Mask is a secondary response emergency Personal Protection Equipment (PPE) designed to provide respiratory protection to the ISS crew in response to a post-fire event or ammonia leak. One size fits all, the fit ranges from the 5th percentile Japanese female to the 95th percentile American male. The Emergency Mask is designed to use two Fire Cartridges (FCs), or two Ammonia Cartridges (ACs. The Emergency Mask will seal around the neck to prevent a crewmember from inhaling contaminants

2.0 Hood Design:

2.1 Hood shall be dark Navy Blue gore fabric with a white Gore lining.

2.1.1 Yoke assembly for the hood adjustment straps

2.2 Hood adjustment strap shall be black 1 inch strapping, nomex or similar material

2.2.1 Attaches to the Yoke assembly

2.2.2 Uses 2 ea “d” rings for adjustment on each side of the yoke, II B fidelity

2.2.3 2 ea retaining loops integrated onto the hood

2.3 Visor is 0.010” thick clear PET polyester film or equivalent

2.3.1 Visor should be resistant to deformation that would prevent the user from reading a checklist/procedure, i.e.

crinkling

2.3.2 Visor material shall be pliable.

2.3.3 Visor shall be treated for Anti-Fog. Material treatment or wipe on application

2.3.4 The visor shall be replaceable

2.3.5 2 ea spare visors shall be provided for each mask

2.4 Nose cup: integrated with respiratory interfaces

2.4.1 Exhalation port 1 ea

2.4.2 inhalation ports with bayonet fittings to support the 3M cartridges 2 ea

2.4.3 Dual bayonet connectors accommodate either:

2.4.3.1 Fire Cartridges 2 ea

2.4.3.2 3M Ammonia Cartridges 2 ea Note: Training cartridges will be provided for testing/fit check and alignment DOT placement

2.5 Neck Seal Design

2.5.1 Neck dam is JSAM neck dam

2.5.2 Material is molded bromo-butyl rubber or similar material

2.5.3 Neck Dam shall be replaceable

2.5.3.1 2 ea spare neck dams shall be provided for each mask.

2.6 Fabricate and install mask labels. See provided photos. Serial numbers will start with SVMF0001

2.7 Option to procure an additional 6 ea Emergency Mask Trainers with spares

3.0 Operational requirement: Hood should inflate when the user “clears” the mask by covering the exhalation port.

Seals at the neck, seal does not need to be maintained after demonstrating the “clearing process”.
