w/ Change 1
4.3.2.6 Stowage. If a TSP stowage tank is not large enough, do not mix a solution stronger than as specified in
4.3.2.5 and attempt to dilute it in the piping system. Failure to maintain the temperature of a solution stronger than as specified in 4.3.2.5 at 160 to 180 °F can result in the TSP precipitating and developing a harden mass. This hardened mass is difficult, if not impossible, to remove. The preferred stowage tank material is stainless steel. Bulk
shipboard stowage of TSP shall be in accordance with NAVSEA S9086-WK-STM-010/CH-670 for alkalies.
4.3.3 Non-ionic detergent (NID).
4.3.3.1 Applicability. NID is a concentrated non-ionic hydrocarbon surfactant that is mixed with water, NOC, or TSP solutions to prepare an aqueous detergent cleaning solution acceptable for use as a pre-cleaner. NID shall be in accordance with MIL-D-16791, Type I, or commercial equivalent, such as Triton X-100.
4.3.3.2 Safety precautions. Follow the safety precautions recommended in the vendor's material safety data sheet (MSDS). In the event any adverse health effects are experienced, cease operations involving NID and consult the cognizant medical department representative for additional guidance.
4.3.3.3 Disposal. Disposal of NID shall be in accordance with local, state, and federal regulations.
4.3.3.4 Compatibility. Appendix A gives the compatibility of NID solutions with various materials. The compatibility of solutions of NID with NOC or TSP shall refer to the respective compatibility tables for NOC or TSP specified in Appendix A. If necessary, perform compatibility testing as specified in A.3.1 of Appendix A.
4.3.3.5 Solution preparation. Prepare NID solution by adding 0.1 to 0.5 ounces of NID to each gallon of water. Prepare NOC and NID solution by adding 0.1 to 0.5 ounces of NID to each gallon of NOC diluted 50 percent with water. Prepare TSP and NID solutions by adding 0.1 to 0.5 ounces of NID to each gallon of water containing 8 to
12 ounces of TSP. NID solutions shall be used at temperatures not greater than 140 °F. At temperatures greater than 140 °F, the solubility of NID will decrease leading to possible precipitation of NID.
4.4 Cleaning solvents.
4.4.1 NAVSEA approved halogenated solvents.
4.4.1.1 Applicability. A NAVSEA approved halogenated solvent, as specified in Appendix E, shall be used as
a final cleaner for instruments as specified in 5.4, for liquid oxygen generating plants and plant piping as specified in
5.8, and for field wipe as specified in 5.10.1.1 and 5.12.4. Use of a NAVSEA approved halogenated solvent for any other application requires local engineering, environmental, and industrial hygiene approval.
4.4.1.2 Safety precautions. For any NAVSEA approved halogenated solvent, follow the safety precautions recommended in the vendor's material safety data sheet and the following:
a. At least two people shall be present at all times while solvent is being used. Do not leave the area unattended while cleaning is in progress.
b. When a halogenated solvent is being transferred by hose or pipe from a remote location, communication shall be established between the pumping station and the space involved.
c. To permit escape in the event of an accidental spill, a self-contained breathing device shall be immediately available to each person in any space where operations involving a halogenated solvent are taking place or occupied spaces where leaks may occur while systems containing halogenated solvents are being cleaned, tested, serviced, or repaired. Each person shall have received instruction and practice in the use of the particular self-contained breathing device to be used. When a spill occurs, a high concentration of solvent vapor may rapidly fill the space and dilute the air in the space. Breathing this diluted, contaminated air can result in rapid (10 to 15 seconds) loss of consciousness caused by oxygen being washed from the lungs. It is therefore necessary to stop breathing until the self-contained breathing device has been put on and is supplying air. The Navy "Emergency Escape Breathing Device" (EEBD) may be used for emergency escape.
