Any fluids will be drained into the containment, removed and disposed of. Perform cleaning and disinfecting as necessary.
3.1.7Upon system opening and after gas free certification is received, blank, cap or bag all openings to prevent spillage from all open components and piping.
3.1.8Accomplish the scope of maintenance or repair as stated in the work specification. . Upon installation aboard ship, an operational test will be conducted IAW the work item.
3.1.9Once the work has been accomplished, all blanks, caps or bags may be removed and the final connection made up. Per the Marine Chemist instructions, either the Marine Chemist or a Shipyard Competent Person shall be present upon blank/spool piece removal to monitor for safe conditions.
3.1.10A copy of this procedure shall be on the job site during the performance of work.

3.3.3Satisfactory operational test, allowable leakage and unobstructed flow none.
3.4DOCUMENTATION FORMS
3.3.1(G) Inspection will be documented on a Test/Inspection Event Authorization form.
3.3.2Shipyard Competent Person Log of Tests and Inspections
3.3.3Marine Chemist Certificate
4.HAZARDOUS MATERIALS / HANDLING REQUIREMENTS:
4.1SAFETY REQUIREMENTS
4.1.1Signs and barrier tape shall be placed surrounding the work area that read: WARNING – CHT Piping System Work. Authorized Personnel Only. No Eating, Drinking, or Smoking.
4.1.2Plastic sheeting will be used to protect equipment from effluent in case of spill.
4.1.3An NFPA Certified Marine Chemist will be present to certify the space and the piping gas free at the initial opening/breaking of all CHT piping to monitor for unsafe conditions. No work shall be accomplished until the space and piping are certified gas free by the Marine Chemist. Per the Marine Chemist instructions, either the Marine Chemist or a Shipyard Competent Person shall be present to monitor for safe atmosphere and conditions when any temporary blanks or spool pieces are removed to facilitate continuing work. Atmospheric conditions shall be monitored and maintained “safe for workers” throughout the duration of the job.
4.1.4Contractor safety department shall ensure all personnel required to wear breathing apparatus are medically qualified and trained.
4.1.5Personnel shall wear protective clothing including overalls, rubber boots, rubber gloves, eye/face shield ( NSTM 593) and hair covering as appropriate when contact with sewage waste is likely during the course of work or cleaning operations. Protective clothing shall not be used for more than one shift.
4.1.6All protective clothing shall be assumed to be contaminated, and handled accordingly. Protective clothing shall be placed in plastic bags at the conclusion of work at the worksite. Fabric clothing shall be placed in one bag for normal laundering. Rubber boots and gloves shall be placed in separate bags prior to being sent out for washing in hot water and a stock detergent prior to reuse by personnel. All bags must be sealed and marked to indicate the nature of its contents before removal from the worksite.
4.1.7All components that are to be removed from the CHT system are to be placed in heavy plastic bags to prevent the spread of contamination.
4.1.8All piping that is removed from the CHT System shall be sealed at all open ends to ensure that the contamination is restricted to the piping.
4.1.9In the event a employee is exposed to CHT and only by direction of a Licensed Health Care Practitioner, a 3-injection series immunization program may be offered to the exposed employee.(This does not apply to nor is it intended as a substitute for the required PPE during work being conducted on shipboard systems, pipes, valves and tanks related to CHT). This immunization series is only in the event of actual personnel exposure.
Because the Hepatitis B virus (HBV) is so aggressive, if you decline this prophylactic treatment, you will be required to sign a waiver to that effect.
4.1.10In case of emergency or spill, notify Prime Contractors Safety Dept and the Ship’s Quarter deck immediately. Suspend all operations, clean up the media using soap and water and a 10% solution of chlorine bleach to disinfect. All “organic material: raw sewage solids found where free liquids are still present – add kitty litter to absorb the liquid. Double bag the media (this is done to discourage vectors and cut down on the smell). Mark the bags with “Raw Sewage Solids” to identify the contents.
At no time may any person contaminated with any sewage leave the immediate area until decontaminated. If personnel are contaminated with sewage, decontaminate with mild soap and water solution or Beta-dine.
Contaminated protective clothing shall be placed in plastic bags at the conclusion of work at the worksite. Fabric clothing shall be placed in one bag for normal laundering. Clothing must not be used for another shift and must be laundered in hot water and detergent. Rain gear must be rinsed and disinfected. Rubber boots and gloves shall be placed in separate bags prior to reuse by personnel. All bags shall be sealed and marked to indicate the nature of its contents before removal from the work site.
All waste generated during the cleaning operation and process will be disposed in accordance wth Environmental, Safety, and Health Requirements. Contractor will be using Bleach, FF Hand Cleaner, Zep-I-Dine and or Detergent as disinfectant only. Waste will be handled in accordance with pre designated WIS. (Contractor expects no Hazardous Waste)
In the event spaces become contaminated with sewage as a result of leaks, spills, or sewage system backflow, the space shall be evacuated immediately. The spill area shall be secured from traffic, a Certified Marine Chemist shall test the area to ensure that the atmosphere is within acceptable gas limits. A safety watch with respiratoryprotection (Supplied Air Respirator/Self-Contained Breathing Apparatus [SAR/SCBA] or air-line mask) shall be posted at the compartment access during cleanup. The spilled sewage shall then be removed or washed down. Respiratory protection shall be used if the atmosphere is not within acceptable limits. If the atmosphere is within acceptable limits, cleanup may be accomplished without respiratory protection; however, respiratory protection shall be kept on hand during the cleanup. The area shall be recertified as gas free at least every two (2) hours and every hour for ambient temperatures above 32.2° C (90° F), or more frequently if deemed necessary bythe Certified Marine Chemist. The need for temporary ventilation shall be determined by a Certified Marine Chemist. A final wash down shall be accomplished with hot, potable water and stock detergent. In addition, food service spaces, berthing areas, and medical spaces shall be treated with an approved disinfectant such as NSN 6840-00-7534797, Disinfectant, Germicidal Fungicidal Concentrate (Phenol Type); or NSN 6840-00-526-1129, Disinfectant, Germicidal and Fungicidal Concentrate (Iodine Type). To be effective, these agents shall be used according to the instructions printed on the labels.
4.1.11List of emergency phone numbers is provided in the attachments and shall be used as appropriate for the spill, causality or other emergency.
