747-400 MAINTENANCE MANUAL
 S 014-034
 CAUTION: LET THE SOLVENTS FROM THE CORROSION-INHIBITING COMPOUND (CIC)
_______ FULLY EVAPORATE. IF CIC GETS ON THE INSULATION BLANKETS BEFORE THE SOLVENTS EVAPORATE, THE INSULATION BLANKET WILL BECOME LESS FLAME-RESISTANT. APPLY CIC (BMS 3-23, BMS 3-26, BMS 3-29, OR EQUIVALENT) ONLY TO METALLIC AIRPLANE COMPONENTS.
 (1)  If Corrosion-Inhibiting-Compound (CIC) contamination of insulation blankets occurs, adhere to the following steps:
 (a)  
Replace the insulation blanket if CIC contamination occurs along the seam.

 (b)  
For all areas except along seams, remove the CIC with Biogenic SE377C, Aliphatic Naptha, Citra-Safe, or equivalent.

 NOTE: If the CIC cannot be removed, replace the blanket.
____
 (c)  In order to prevent corrosion-inhibiting compound (CIC) contamination of insulation blankets, obey the following steps prior to blanket installation:
 NOTE: Adjust the ventilation times of the following steps
____ upward to achieve satisfactory drying. Drying depends on the temperature, humidity, and quantity of CIC.
 1) Ventilate areas, after application of CIC such as BMS 3-23, for a minimum of 1 hour. 2) Ventilate area, after application of CIC such as BMS 3-26 or BMS 3-29, for a minimum of 4 hours.
 S 624-009
 (2)  
Apply the corrosion preventative compound, BMS 3-23, to the structure, as necessary (AMM 51-24-13/701).

 S 434-010

 (3)  
Repair or install the dacron cord for the insulation blankets to be installed at the bottom of the lower lobe, if necessary.

 S 114-019
 WARNING: DO NOT GET SOLVENTS IN YOUR MOUTH, OR YOUR EYES, OR ON YOUR
_______ SKIN. DO NOT BREATHE THE FUMES FROM SOLVENTS. SOLVENTS ARE HAZARDOUS MATERIALS. SOLVENTS MAY BE FLAMMABLE OR HARMFUL TO THE ENVIRONMENT. REFER TO PRODUCT MATERIAL SAFETY DATA SHEETS (MSDS) AND LOCAL REQUIREMENTS FOR PROPER HANDLING PROCEDURES.
 (4)  Use methyl ethyl ketone or Acetone to clean the structure before you install velcro tape or double-back tape to the structure.
