Introduction Heavy metal like mercury was used directly or indirectly since long ago before it was stopped around the world. Since, the value of the metal and its availability in different use in medical appliances is still one of the burdens in developing country like Nepal. The main uses of mercury are in dental amalgam, sphygmomanometers, and thermometers. The mercury once released into the environment can remain for a longer period. Both acute and chronic poisoning can be caused by it. Half of the mercury found in the atmosphere is human generated and health care contributes the substantial part to it. WHO and UNEP issued new guideline for health care sector to become mercury free.

Aim and methods To find out the Knowledge, attitude and practice due to hazards of mercury contact among paramedics and patients.

Results and conclusion 938 paramedics and 890 patients were asked in­depth structured questions about mercury hazards and update knowledge. Overall 18% of the paramedics have no knowledge of mercury­free with respect to 69% of the patients. Around 49% of paramedics have broken mercury thermometer in their career and contact with skin. However, 1.2% patient only have a similar history in their life time. 4% of the contamination with mercury having SKIN problems. 32% of the patients still have mercury thermometer and sphygmomanometer in their home with respect of 0.6% of paramedics. The above study showed that Healthcare worker has more knowledge of Mercury hazards than patients groups. However, paramedics have broken the mercury instruments than patients party. Similarly, Paramedics have Mercury free device at home than patients groups. It means awareness, literate people having more knowledge towards its practice making mercury free society in a resource poor country like Nepal.
