  2. CHILLED CARGO: CHEESE, EGGS AND FRESH VEGETABLES. -2 OC TO 6OC.
  3. AIR COOLED CARGO: FRUITS. 2 OC TO 12OC.

PREPARATION OF CARGO HOLD:

  1. THE COMPARTMENT MUST BE CLEAN, DRY AND FREE OF ANY ODOUR OR TAINT,
  2. HOLD MUST BE DEODORISED WITH MILD AGENTS (LIME, OZONE),
  3. BILGES TO BE CLEANED, DRY, DEODORISED AND SUCTIONS CHECKED,
  4. THE INSULATION AND PERMANENT DUNNAGE TO BE CHECKED AND REPAIRED AS NECESSARY,
  5. SCUPPERS TO BE CLEANED,
  6. BRINE TRAPS TO BE CHECKED, TESTED AND REFILLED,
  7. THERMOMETERS TO BE IN POSITION,
  8. VENTILATOR PLUGS IN POSITION AND TIGHTLY WEDGED,
  9. BRINE PIPES TO BE TESTED TO ENSURE THEY ARE NOT CHOCKED AND THAT NO LEAKS OCCUR AT THE JOINTS.

PRECOOLING OF THE COMPARTMENT:

  1. THE COMPARTMENT SHOULD BE COOLED DOWN PRIOR TO LOADING TO A TEMPERATURE SLIGHTLY LOWER THAN THE TRANSIT TEMPERATURE,
  2. DUNNAGE LAID IN THE COMPARTMENT SHOULD ALSO BE COOLED DOWN OTHERWISE IT WILL STAIN THE CARGO,

PRECAUTIONS DURING LOADING:

  1. REEFER CARGO SHOULD BE LOADED ONBOARD ONLY UNDER THE SUPERVISION OF A RECOGNIZED SURVEYOR,
  2.  CARGO SHOULD NOT BE ALLOWED TO WAIT FOR LONG TIME ON THE QUAY,
  3. HOLD SHOULD BE PRE-COOLED TO TEMP BELOW THE CARRIAGE TEMP,
  4. DAMP, WET AND TORN PACKAGES SHOULD BE INSPECTED IF THE CARGO HAS DETERIORATED. IF THE CARGO IS FINE THEN ONLY IT SHOULD BE LOADED AFTER RE-PACKING,
  5. CONTENTS OF AT LEAST 5-10% CARTONS SHOULD BE EXAMINED FROM EACH HOLD ON A RANDOM BASIS,
  6. CARTONS WITH SOFT OR DRIPPING CONTENTS SHOULD BE REJECTED,
  7. REFRIGERATION OF HOLDS SHOULD BE TURNED ON DURING LONG BREAKS AND DURING MEAL BREAKS,
  8. ONCE LOADED, THE CARGO SHOULD BE COVERED WITH TARPAULIN,
  9. DURING OPERATIONS, THE FROST FORMED ON TOP OF THE BRIPE PIPES SHOULD BE BRUSHED CAREFULLY. IT SHOULD NOT FALL ON TOP OF THE CARGO.
  10. IN TROPICAL CLIMATES AVOID LOADING IN THE NOON. TRY TO LOAD CARGO DURING NIGHT TIME,
  11. UPON COMPLETION OF LOADING, THE REEFER CHAMBER MUST BE CLOSED AIR TIGHT AND COOLING RESUMED IMMEDIATELY.

PRECAUTIONS DURING LOADING

  1. CARGO MUST BE STOWED IN ORDER TO ALLOW FREE CIRCULATION OF AIR THROUGH AND AROUND THE STOW.
  2. LAYING OF DUNNAGE SHOULD BE SUCH THAT IT DOES NOT OBSTRUCT DESIGNED AIR FLOW PATTERN IN THE COMPARTMENT,
  3. SIDES AND BULKHEADS SHOULD BE FITTED WITH VERTICAL DUNNAGE TO KEEP CARGO AWAY FROM THE STRUCTURE,
  4. REEFER CHAMBERS MUST BE DIVIDED WITH AIR CHANNELS FOR EACH BLOCK NOT EXCEEDING 3 MTRS. CHANNEL MUST BE ATLEAST 10CMS WIDE AND ALIGNED TO FACE THE COOL AIR OUTLETS. THERE SHOULD BE AN EVEN GAP OF ATLEAST 30 CMS BETWEEN THE CARGO TOP AND THE LOWEST PART OF THE DECKHEAD.
  5. DUNNAGING SHOULD BE EFFICIENTLY CARRIED OUT SO AS TO AVOID STOW COLLAPSING INTO THE AIR CHANNELS,

EACH LOT OF CARGO TO BE LOADED ACCORDING TO THE B/Ls AND SEPARATED BY USING COLOUR TAPES OR NET. AVOID LOADING CARGO FOR MORE THAN 1 PORT IN ONE CHAMBER. CARGO ONCE LOADED SHOULD NOT BE SHIFTED. THESE MEASURES WILL HELP PREVENT TEMPERATURE FLUCTUATIONS.
