on compliance with the safety procedures in chemical and specialized laboratories

of M.Auezov South Kazakhstan State University




We, the representatives of the student body of M.Auezov South Kazakhstan State University gathered within the walls of our university in Shymkent city for the meeting of the Student Council, held on 22 December, 2014. On behalf of the students of our University, we have taken the following initiative to observe the following safety procedures when working in chemical and specialized laboratories.




The Student Council of M.Auezov SKSU considers this initiative as an important step to understanding of the importance of safety procedures by students when working in laboratories. This initiative is taken by all students of the University, specialties that include laboratory classes in chemical and specialized laboratories. The basis for the adoption of this initiative was a misunderstanding of the importance of compliance with safety procedures by students when working in laboratories and the need to improve familiarization procedures of students with safety requirements.


Possible risks


We are aware that the requirements of safety rules when working in chemical and specialized laboratories are aimed at reducing the dangerous risks in conducting laboratory and practical works. Risk factors consist in thermal and chemical injuries, poisoning by toxic fumes, cuts and electric shock. We realize that it is very important to know, understand and strictly comply with the requirements of labor safety instructions when working in a chemical or a specialized laboratory. We confirm that before working in the laboratory we have to pass the instructions on labor safety, medical inspection and have no contra-indications for health.








Safety requirements

We undertake to comply with:

- the following safety requirements before starting the work:


1. Pre-plan the work with a teacher;

2. Prepare personal protective means for using in working with toxic and corrosive materials;

3. Wash hands thoroughly with soap and water;

4. Prepare necessary equipments, laboratory glassware, reagents, devices, materials and supplies for working;

5. Make sure that ventilation system, a fume hood and a dry box is in good condition;

6. Check the individual fire-fighting equipment and rendering the first aid for consistency of: the first aid kit, fire extinguisher, felted cloth or woolen blanket, sand box;

7. Immediately inform the supervisor at detection of hardware malfunction or any signs of possible errors (smoke, flame, smell, etc.).


- the requirements for the use of personal protective means:


1. Working in a laboratory we should wear a denim coats. The hair should be taken away;

2. Carrying out the works with the release of toxic gases and dust, we should use respirators or gas masks and other protective means for respiratory organs;

3. Working with corrosive and toxic substances we should use also protective aprons, personal protective means for eyes and hands;

4. We should use rubber gloves to protect hands from the impact of acids, alkalis, salts, solvents;

5. Gloves should not have cuts, punctures or other damages. Before wearing gloves we should sprinkle them with talc on the inside;

6. For eye protection we must wear glasses of various types, shields, masks.


- the next safety requirements during the work:

1. Working in the laboratory we should keep it clean, follow silence and order in the workplace;

2. We should not taste any substance;

3. If we need to identify the smell of gases released during the reaction we need direct gas from the neck of a flask to the nose slightly by palm and gently breathe it;

4. During the work we must be sure that the matter will not fall on the skin of our face and hands, because many substances can cause irritation of the skin and mucous membranes;

5. Experiments should be performed only in a clean container;

6. We should take vessels with substances or solutions in one hand by the neck, and in another one support the bottom of it;

7. Solutions should be poured from the vessel so that when tilting the label should be above (the label - in hand!)., we should remove the drop, remaining on the container neck with the top edge of the flask which is filled with liquid;

8. When using a pipette it is strictly forbidden to draw fluid by mouth;

9. Take solid chemical agents only with a spatula, tweezers or a spoon (not with hands!).

10. Carry out the work with solid alkali only in protective glasses and gloves;

11. Pour liquids out using chemical funnel. To avoid the damage of the label of a flask from which we pour the liquid out, we should keep it with the label in hand;

12. When heating liquid and solid substances in test tubes and flasks we should not direct their holes to ourselves and neighbors. It is also forbidden to look from the top in open vessels heated to avoid possible injury as a result of a chemical reaction;

13. We should carry out all experiments with toxic and odorous substances in a fume hood;

14. When heating substances and solutions in the tube we should use a holder. Opening the tube should be directed away from yourself and other students;

15. When dilution of concentrated acids and alkalis in small portions we should pour acid (or concentrated alkali solution) in water, not vice versa;

16. Hazardous reactions we should pour out only the relevant banks in the hood;

17. We must abide by all rules of using electrical appliances.

Before plugging in the unit we should check visually the serviceability of conductor wires and grounding. During the experiment we should not left the device unattended. It is not allowed to take parts of the device by hand that are in motion, to take the pulley of the electric motors and electrically conductive parts of the instrument. We should not lubricate and clean the device while it is running. At the end of the operation of a unit we must disconnect it from electricity. In case of accidental electric shock, immediately turn off the electricity and call a doctor;

18. Do not leave the electric heating and other electrical devices switched on after completion of a work;

19. Never touch the exposed contacts on laboratory shields, as well as the contacts on the electric motors, electric heaters, etc.;

20. When working on installations with the details, we must be especially careful: not to touch these parts and ensure that overhanging edge of clothing does not fall on them;

21. With all arising issues we must immediately refer to the teacher;

22. It is strictly forbidden to pour concentrated solutions of acids and alkalis into washbasins, as well as various organic solvents, strong-smelling and flammable substances. All wastes must be drained into a special glass container with a capacity of not less than 3 liters with cover (for later neutralization);

23. It is strictly forbidden to take food in the laboratory.


- the following safety requirements at the end of the work:


1. Put the workplace in order;

2. Do not spill unspent reagents out and pour them back into those vessels, where they were taken;

3. Pour the spent solutions of reagents out into a special glass container with a lid, with a capacity of not less than 3 liters (for later neutralization and destruction);

4. Turn laboratory equipment, drawing ventilation and other electrical appliances off;

5. Remove the protective clothing and personal protective means;

6. Wash hands thoroughly with soap and water;

7. Thoroughly ventilate the area.


- the following safety requirements in emergency situations:

Stated below

1. In cases of broken glassware, do not collect the shards with bare hands, and use brush and shovel for this purpose;

2. Clean spilled and scattered reagents with the requirements of instructions for working safely with the appropriate chemical reagents;

3. In the case of spilled flammable liquid and their ignition immediately inform the nearest fire station and start fire extinguishing with the help of primary fire extinguishing means (fire extinguishers, sand or cover with felted cloth);
