    I gather from this thread that your not certified to work with ammonia in such concentrations found in absorption refrigeration, household ammonia is between 5 and 10%. Ammonia in higher concentrations would require certification.

    One mistake and the Hazmat team will be all over you like fleas on a dog, your first mistake is taking on a project your not qualified to do.You'll end up paying more money in fines and court costs that you'll make on this project.

    I see your from Kamloops, why not contact the fellow on the highway heading into Armstrong and another shop in Enderby who repairs RV fridges and see if they are interested in buying some of your cooling units.

    Ammonia is considered a high health hazard because it is corrosive to the skin, eyes, and lungs.

    Exposure to 300 ppm is immediately dangerous to life and health. If the possibility of exposure above 300 ppm exists, use a MSHA/NIOSH approved self-contained breathing apparatus with a full facepiece operated in a pressure-demand or other positive-pressure mode.

    Ammonia is also flammable at concentrations of approximately 15 to 28% by volume in air. When mixed with lubricating oils, its flammable concentration range is increased. It can explode if released in an enclosed space with a source of ignition present, or if a vessel containing anhydrous ammonia is exposed to fire.
