CONTAINER: Store liquid nitrogen container securely in upright position in a dry, well ventilated area and away from incubator intakes and chicken boxes.
Liquid nitrogen container and vaccine should be handled only by properly trained personnel regarding the use of, precautions and safe practices for liquefied atmospheric gases (particularly liquid nitrogen).
When removing ampule cane, handling frozen ampules, or adding liquid nitrogen, wear long sleeves, a plastic face shield and gloves to protect the skin from contact with the liquid nitrogen. All storage and handling of the liquid nitrogen container must be in a dry, ventilated area. Do not inhale liquid nitrogen vapors. If drowsiness occurs, get fresh air quickly; then ventilate entire area. If breathing difficulty occurs, apply artificial respiration. If any of these difficulties persist or there is a loss of consciousness, summon a physician immediately.
Care should be exercised to prevent contaminating your hands, eyes and clothing with the vaccine.
Preparation Of Vaccine
READ ABOVE SAFETY PRECAUTIONS ON HANDLING VACCINE AMPULE. AMPULES HAVE BEEN KNOWN TO EXPLODE ON SUDDEN TEMPERATURE CHANGES. DO NOT THAW IN HOT OR ICE COLD WATER.
1. Before withdrawing vaccine from liquid nitrogen canister, protect hands with gloves, wear long sleeves and use a facemask or goggles. It is possible an accident could occur with either the liquid nitrogen or the ampules of vaccine. When removing an ampule from the cane, hold palm of gloved hand away from body and face.
2. When withdrawing a cane of ampules from canister in liquid nitrogen container, expose only the ampules to be used immediately. We recommend handling a maximum of 4 ampules at a time. The remaining ampules should be replaced immediately in the canister of the liquid nitrogen container.
3. The contents of the ampule are thawed rapidly by immersing in a container of clean water at a temperature range of 20-30°C (68-86°F). Once the vaccine has thawed remove ampule from water bath. Gently swirl the ampule to disperse contents. Then break ampule at its neck and immediately proceed as below.
4. Dilute the vaccine for administration. Use 100 ml sterile diluent for each 1,000 doses of vaccine to administer 0.1 ml dose per chicken embryo or use 50 ml for each 1,000 doses of vaccine to administer 0.05 ml per chicken embryo by the in ovo route. Use 200 ml sterile diluent for each 1,000 doses of vaccine to administer 0.2 ml dose per chicken by the subcutaneous route.
5. Draw contents of ampule into a sterile 10 ml syringe, mounted with an 18 gauge needle.
6. Dilute immediately by filling the syringe slowly with a portion of the diluent.
IMPORTANT: THE DILUENT SHOULD BE AT ROOM TEMPERATURE 16-27°C (60-80°F) AT TIME OF MIXING.
7. Slowly empty the syringe into the prepared diluent bag. Withdraw a portion of the diluent with the syringe to rinse ampule. Remove the remaining diluent from the ampule and inject gently into the diluent bag. Mix gently.
8. Fill the previously sterilized automatic syringe or egg inoculation machine according to the manufacturer’s recommendations.
9. The vaccine is now ready for use.
