TASK 30-45-00-040-002-A
Deactivation of the Rain Repellent System

WARNING: DO NOT GET THE FLUID ON YOUR SKIN OR IN YOUR EYES. IF YOU DO:
  • FLUSH IT AWAY WITH CLEAN WATER
  • GET MEDICAL AID.
WARNING: MAKE SURE THAT THE CIRCUIT BREAKERS RELATED TO THE WEATHER RADAR ARE OPENED, SAFETIED AND TAGGED.
WARNING: MAKE SURE THAT YOU DEPRESSURIZE THE RAIN REPELLENT SYSTEM BEFORE YOU REMOVE THE RAIN REPELLENT FLUID-CAN. RAIN REPELLENT FLUID CAN COME OUT SUDDENLY IF YOU REMOVE THE FLUID CAN WITH THE SYSTEM PRESSURIZED.
WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
CAUTION: MAKE SURE THAT THE FLUID DOES NOT STAY ON THE AIRCRAFT STRUCTURE. IF THE FLUID GETS ON THE AIRCRAFT STRUCTURE, WASH IT OFF IMMEDIATELY WITH SOAP AND WATER.
CAUTION: DO NOT APPLY THE RAIN REPELLENT FLUID ON A DRY SURFACE.
NOTE: If there is leakage of FORALKYL 2211, you can smell a pine odor.
