Safety Precautions: Attention and adherence to safety considerations is important in a power electronics laboratory. Power electronic circuits can involve voltages of several hundred volts and currents of several tens of amperes. General precautions for the power electronics laboratory are: 1 Be calm and relaxed, while working in laboratory. 2 Keep the work area neat and clean and remove papers lying on table or nearby circuits. 3 When working with voltages over 40V or with currents over 10A, take extra care. 4 A switch should be included in each supply circuit so that when opened, these switches will de-energize the entire setup. Place these switches so that you can reach them quickly in case of emergency, and without reaching across hot or high voltage components. 5 Use only isolated power sources, i.e., either the isolated power supplies or AC power through isolation power ransformers. This helps using a grounded oscilloscope and reduces the possibility of risk of completing a circuit through your body or destroying the test equipment. 6 When connecting the power supply and load to the experimental board, the sequence of the connection to be made is from the load to the power supply, which helps to avoid any floating wire or connector to be charged or shorted to each other. Never let connection wires connected to the power supply or the out put port of the experimental board to be floating. 7 Check for all the connections of the circuit and scope connections before powering the circuit, to avoid shorting or any ground looping, which may lead to electrical shocks or damage of equipment. 8 Check your wiring and circuit connections point-to-point of the circuit diagram.

SAFETY SCREEN To avoid any chance of burning from chemical reaction and any other experiment which can cause injury at time of observing the results of that experiment a safety screen made of a transparent thick acrylic sheet divided into three parts (300 x 600) mm approx. each can be used. Outer sides can flap across their vertical axis as per the requirement of the experimental set up. Folding assembly give an advantage to store it easily. Overall dimensions (900 x 600) mm approx.

FIRST AID FOR LABORATORY CHEMICALS

ACCIDENTS CAUSED DUE TO ACIDS

BODY BURNS Wash with plenty of water first and then with Sodium bicarbonate solution. After the wash, apply a paste of Sodium bicarbonate –Petroleum jelly mixture on the burnt part for 10-15 minutes. Again Wash with plenty of water and apply Carron oil (An equal quantity of Lime water and Linseed oil)

SPILLAGE IN THE EYES Wash with plenty of water first and then with 2% Sodium bicarbonate Solution followed by water again. Wipe out the water from your eyes And then put 2-3 drops of Olive oil.

SPILLAGE ON CLOTHS Use dilute Ammonia solution to neutralize the acid. Then wash with Plenty of water.

ORAL INTAKE Gargle with water first and then drink atleast 1 litre of milk or water Followed by lime juice.

ACCIDENTS CAUSED DUE TO ALKALI

BODY BURNS Wash with plenty of water first and then Boric acid solution. Make a paste of Boric acid, apply on the burnt part and after 10-15 minutes wash it off.

SPILLAGE IN THE EYE Keep open the eyelids and wash with plenty of water first and then with Dilute Boric acid solution (0.5%). Again clean your eyes with water. Wipe out the water and put 2-3 drops of Olive oil.

SPILLAGE ON CLOTHS Neutralise the alkali with dilute Acetic acid solution (3%). Then wash with plenty of water.

ORAL INTAKE Gargle with water first and then drink atleast 1 litre of milk of water. Eat Orange.

BURNS CAUSED BY BROMINE Wash the burnt part with either Alcohol or Petrol and then apply Olive Oil.

BURNS CAUSED DUE TO FIRE Apply either Petroleum jelly or Burnol on the burnt part.

WOUND First remove any foreign particle (like glass pieces etc.) from the wound. Clean well with water and apply Tincture iodine, put a bandage and seek medical attention.

GENERAL ADVICE For serve burns caused due to acid keep the burnt part in Sodium bicarbonate – Petroleum jelly mixture and for those burns caused due to alkali, keep in the Boric acid solution for atleast half an hour.

While packing compounds of Cobalt, Chromium, Cadmium, Bismuth, Barium, Lead, Tin etc., it is necessary to wear the respective safety Equipments/guards (like gloves, goggles, face mask etc.). In case these Chemicals are accidentally consumed try to spit it out even by vomiting.

While packing Formaldehyde or Hydrogen peroxide. If it falls on the body or clothes, wash with plenty of water.

If Copper Sulphate is consumed accidentally, drink a cup of warm water containing a spoon of Sodium chloride or Zinc Sulphate.

It is the duty of everyone to ensure that chemicals do not come into contact with the body through their mouth, eyes, ears and nose. Also ensure that the necessary safety equipments are used.

After providing first aid, seek medical attention, if necessary.

FIRE Do not use water to extinguish an electric fire as it could give you a shock. Use dry powder fir extinguishers.

If solvents lighter than water (like Xylene, Benzene, Acetone. I.P.A. Acetone. Methanol, Petroleum ether, Diethyl ether, etc.) catch fire, use wet blanket to cover the fire or use a suitable fire extinguisher. Splashing water on such fires could spread the flame. Be familiar with the usage of various types of fire extinguishers.

Use full length Apron or protective coat / gown in the laboratory 1199 3125995 Petroleum ether 60 - 800C GD 25 L 2. Wear Safety goggles for the safety of eyes from the splashing of 1200 3126000 Potassium chloride PD 25 kg 1201 3126005 Potassium dichromate PD 25 kg chemicals. 1202 3126010 Poatssium nitrate PD 25 kg 3. Wear suitable inert gloves on the hands while handling chemicals, 1203 3126015 Sodium bicarbonate PD 25 kg specially, corrosive, poisonous or toxic chemicals. Always avoid 1204 3126020 Sodium carbonate anhydrous PD 25 kg 1205 3126025 Sodium chloride PD 25 kg direct contact of chemicals with the naked hands. 1206 3126030 Sodium chloride A.R. PD 25 kg 4. Thoroughly wash hands before and after the job. 1207 3126035 Sodium hydroxide flakes PD 25 kg 1208 3126040 Sodium hydroxide pellets PD 25 kg 5. A rubber bulb should be used for pipetting solutions. 1209 3126045 Sodium sulphate PD 25 kg 6. Experiments involving toxic reagents or solvents or those 1210 3126050 Sodium sulphite PD 25 kg accompanied by toxic gaseous evolutions, must be conducted in 1211 3126055 Toluene rectified GD 25 L 1212 3126060 Xylene rectified GD 25 L an efficient fume cup-board. 1213 3126065 Zinc sulphate PD 25 kg 7. Laboratory must be Kept Clean and tidy at all times. 8. Each person working in the laboratory must ensure that he or she is fully aware of the laboratory safety devices such as Fire Extinguisher, fire Blankets, First Aid Kits, Drench Showers etc., and their normal application or usage. 9. Always prefer separate bins with lids at the top for broken glassware and for flammable material. Always ensure prompt removal of such waste from the laboratory. 10. Each Laboratory must be fully equipped with all safety aids, such as First Aid Box, Fire Blanket etc. 11. After using the Chemicals, the containers should be tightly closed and returned to its original place. Corrosive chemicals should preferably be stored separately in corrosion resistant chamber. 12. Use the minimum desired quantity of reagents. Use of chemicals in excess is hazardous as well as wastage of money. 13. Strong acids used for conducting experiments should be diluted before being poured into the sink directly. 14. When the burners are not being used, lower the flame. As soon as the work is over, thoroughly close the supply to the burners. 15. Once the reagent has been taken out from its container, never pour it back with the original one, even if it is in excess, to avoid contamination. 16. The stoppers or caps of the reagent container should not be changed with that of others to avoid contamination of chemicals. 17. Always use suitable handling device while handling chemicals. 18. Never lift the container or bottle from their neck or cap or stopper. 19. Don't eat, drink or smoke in the laboratory or store rooms. 20. Don't throw filter papers of solid wastes in the sink to avoid their choking. 21. Flammable solvents like benzene, alcohol, ether, carbon disulphide etc., should never be handled in the presence of ON or Chemical packaging and the environment: where possible we use only recyclable or biodegradable operational burners, heaters etc. Also, such solvents should never packing. be kept in open containers.
