Updated QA - COTS TrailerModification - 24 Sept 2026.docx

22 Sept 2026 V1 COTS Trailer/Modification Propulsion System Rocket Engine Transport Trailer (PTT2)

RFI Q&A:

1. Q: PSRE Container Envelope: what is the length of each Container? (Ref PWS 3.1) A: It is cylindrical, so the diameter listed is what should be used. The diameter is 70.86” and the height is 61.82.

2. Q: Integrated floor Tie-downs: PSRE Container load anchorage: is there the opportunity to modify the containers to accept standard ISO container attachment points? (Ref PWS 3.2) A: We are open to suggestions but modifying the container is currently out of the scope for this project.

3. Q: Is it possible to get a copy of a basic drawing of the containers? (Ref PWS 3.2) A: The Government will not be distributing actual engineering drawings of the PSRE shipping containers during this RFI market research phase. For the purposes of evaluating trailer floor-space, door clearance, and tie-down feasibility, vendors should utilize the unclassified envelope dimensions provided: the container is a cylinder with a maximum outer diameter of 70.86 inches, a height of 61.82 inches, and a loaded weight of approximately 2,500 lbs.

4. Q: Side Door requirements: Are side doors an absolute requirement; there are other COTS options for quick side loading and unloading? (Ref PWS 3.2) A: Side doors are not required for commercial transport. However, the assets need to be tied down and protect the container from vibration to a level of 3G. Side loading provides the ease of loading while staying connected to bldg. ground system until transferred to trailer grounding system.

5. Q: Chemical Compatibility: Monomethyl hydrazine (MMH) and Nitrogen Tetroxide (NTO), are data sheets available for these chemicals, or should we pull information from the web? (Ref PWS 3.4)

A: See attached data sheets

6. Q: Are there any security requirements for access to the finished and loaded trailer(s)? (Ref PWS 3.4) A: Yes, once loaded and locked no access will be granted to the load until at destination for the ammo in process. 2-man crew is used to ensure asset is attended and route is continuous.

7. Q: Does the COTS trailer solution need to be complaint with DoT, DoW, and AFMAN 91 201 explosive/propellant transport rules?

A: Yes, the trailer will need to be compliant with those regulations in addition to the CFR Title 49.

8. Q: Will this project have requirements for using CUI data? Most COTS trailer suppliers are not CMMC-2 self-assessment compliant.

A: Yes, this project will have CUI data. We are currently looking into tailoring our drawings to a basic level to remove CMMC requirements. More to come.

Vapors are a strong irritant to the pulmonary tract. Contact with liquid causes a severe corrosive action on the skin or eyes. Initial symptoms of inhalation may be moderate and include irritation of the eyes and throat, tightness of the chest, headache, nausea and gradual loss of strength. Severe symptoms may be delayed (possibly for 5 to 7 hours) and include cyanosis, increased difficulty in breathing, irregular respiration, lassitude and possible eventual death due to pulmonary edema in untreated cases.

The vapor is highly toxic and hazardous because of its ability to cause delayed chemical pneumonitis and pulmonary edema. Chronic or repeated exposure may cause permanent decrements in pulmonary function (silo filler’s disease).

The absence of marked acute irritation of nitrogen dioxide limits its warning properties. Contact with the liquid causes a corrosive or chemical etching action on the skin or eyes.

Neither nitrogen dioxide or nitrogen tetroxide are listed in the IARC, NTP or by OSHA as a carcinogen or potential carcinogen

(Continued on Page 4)

PROMPT MEDICAL ATTENTION IS MANDATORY IN ALL CASES OF OVEREXPOSURE TO NITROGEN DIOXIDE.

RESCUE PERSONNEL SHOULD BE EQUIPPED WITH SELF-CONTAINED BREATHING APPARATUS AND WEAR

PROTECTIVE CLOTHING AND BOOTS IF THE LIQUID HAS SPILLED OR IS BEING DISCHARGED.

Inhalation: Conscious persons should be carried (not assisted) to an uncontaminated area and breathe fresh air supplemented with oxygen. Keep the patient warm, quiet and under competent medical observation until the danger of delayed pulmonary edema has passed (at least 72 hours). Any physical exertion during this period should be discouraged as it may increase the severity of the pulmonary edema or chemical pneumonitis. Bed rest is indicated.

Nitrogen dioxide is extremely reactive and is a strong oxidizing agent. It explodes on contact with alcohols, hydrocarbons, organic materials and fuels. Nitrogen dioxide decomposes on contact with water to produce nitric and nitrous acids. It acts as a catalyst for the explosive reaction of oxyqen and hydrogen.

Use only in well-ventilated areas. Valve protection caps and valve outlet threaded plugs must remain in place unless container is secured with valve outlet piped to use point. Do not drag, slide or roll cylinders. Use a suitable hand truck for cylinder movement. Do not heat cylinder by any means to increase the discharge rate of product from the cylinder.

Use a check valve or trap in the discharge line to prevent hazardou back flow into the cylinder.

For additional handling recommendations, consult Compressed Gas Association’s Pamphlet P-1.

Protect cylinders from physical damage. Store in cool, dry, well-ventilated area away from heavily trafficked areas and emergency exits. Do not allow the temperature where cylinders are stored to exceed 125ºF (52ºC). Cylinders should be stored upright and firmly secured to prevent falling or being knocked over. Full and empty cylinders should be segregated. Use a “first in - first out” inventory system to prevent full cylinders being stored for excessive periods of time.

For additional storage recommendations, consult Compressed Gas Association’s Pamphlet P-1.

Anhydrous nitrogen dioxide is noncorrosive to most metals at normal temperatures. It does corrode copper and its alloys. Teflon® is the preferred gasket material.

OTHER RECOMMENDATIONS OR PRECAUTIONS

Keep equipment scrupulously dry. Compressed gas cylinders should not be refilled except by qualified producers of compressed gases. Shipment of a compressed gas cylinder which has not been filled by the owner or with his (written) consent is a violation of Federal Law (49CFR).

HEALTH HAZARD DATA

TOXICOLOGICAL PROPERTIES: (Continued)

Persons in ill health where such illness would be aggravated by exposure to nitrogen dioxide should not be allowed to work with or handle this product.

RECOMMENDED FIRST AID TREATMENT: (Continued) given assisted respiration and supplemental oxygen. Once respiration has been restored, they should be treated as above.

Eye Contact: PERSONS WITH POTENTIAL EXPOSURE TO NITROGEN DIOXIDE SHOULD NOT WEAR

CONTACT LENSES.

Flush contaminated eye(s) with copious quantities of water. Part eyelids to assure complete flushing. Continue for a minimum of 15 minutes.

Skin Contact: Flush affected area with copious quantities of water. Remove affected clothing as rapidly as possible.

Subsequently treat as for a thermal burn.

FIRE AND EXPLOSION HAZARD DATA

SPECIAL FIRE FIGHTING PROCEDURES: (Continued)

Continued application of large quantities of water will eventually dilute the oxidizers so that combustion is no longer supported. The remaining airsupported fire may be extinguished by the appropriate method.

SPECIAL PRECAUTONS

OTHER RECOMMENDATIONS OR PRECAUTIONS: (Continued)

Always secure cylinders in an upright position before transporting them. NEVER transport cylinders in trunks of vehicles, enclosed vans, truck cabs or in passenger compartments. Transport cylinders secured in open flatbed or in open pick-up type vehicles.
