TASK 38-31-61-210-001-A
Detailed Inspection of Cleanliness inside the Waste Tank

WARNING: DO NOT DO WORK ON THE TOILET WASTE SYSTEM AND THE POTABLE WATER SYSTEM AT THE SAME TIME. THIS WILL PREVENT CONTAMINATION OF THE POTABLE WATER SYSTEM. SUCH CONTAMINATION CAN BE DANGEROUS TO HEALTH.
WARNING: ALWAYS USE RUBBER GLOVES WHEN YOU DO WORK:
  • ON THE TOILET WASTE SYSTEM, OR
  • ON PARTS THAT HAVE CONTAMINATION FROM THE WASTE SYSTEM.
WHEN YOU COMPLETE THE WORK PROCEDURE, CLEAN YOUR HANDS WITH SOAP AND WATER. THIS WILL PREVENT INFECTION (TOILET WASTE IS DANGEROUS FOR HEALTH).
WARNING: WHEN YOU REMOVE A COMPONENT OF THE TOILET WASTE SYSTEM, ALWAYS DISINFECT THE PART BEFORE YOU PUT IT IN A PLASTIC BAG, THEN SEAL THE BAG. DO NOT PUT DOCUMENTS INTO THE PLASTIC BAG. SEAL THE BAG FIRST,THEN ATTACH THE DOCUMENTS TO IT. THIS WILL PREVENT INFECTION OR ILLNESS. CONTAMINATION FROM THE WASTE CAN BE DANGEROUS TO HEALTH.
WARNING: BE CAREFUL WHEN YOU USE CONSUMABLE MATERIALS. OBEY THE MATERIAL MANUFACTURER'S INSTRUCTIONS AND YOUR LOCAL REGULATIONS.
