Safe Use and Storage of Chemicals and ReagentsTapeshwar Yadav
Even in the smallest laboratory, dangerous chemicals are used directly or incorporated into stains and reagents.
Hence the correct handling and storage of hazardous chemicals is essential to prevent injury and damage.
In addition to this, to reduce accidents caused by chemicals, labeling is very important.
Laboratory Hazards, Accidents and Safety RulesTapeshwar Yadav
Injury, damage and loss by fire can be minimized when laboratory staff:
Understand how fires are caused and spread;
Reduce the risk of fire by following fire safety regulations at all times;
Know what to do if there is a fire in their laboratory;
Know how to use fire fighting equipment;
Know how to apply emergency First Aid, for burns.

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

4. General Safety Rules
7. Roll up loose sleeves.
8. Know the location of the fire
extinguisher, fire blanket, eyewash
station, and first aid kit.
9. Keep your work area uncluttered. Take
to the lab station only what is
necessary.
5. General Safety Rules
10. It is suggested that you wear
glasses rather than contact lenses.
11. Never put anything into your mouth
during a lab experiment.
12. Clean up your lab area at the
conclusion of the laboratory period.
13. Never “horse around” or play
practical jokes in the laboratory.
6. Glassware Safety
1. Chipped or cracked glassware should
not be used. Show it to the teacher.
2. Broken glassware should not be
disposed of in a classroom trashcan.
There is a special glass disposal
container for it.
3. When pouring liquids into glassware,
make sure the container you are
pouring into is resting on a table at
least a hands breadth from the edge.
7. Glassware Safety
4. Pour down a glass stirring rod to prevent
liquids from splattering.
5. If a piece of glassware gets broken, do
not try to clean it up by yourself. Notify
the teacher.
6. When inserting glass tubing into a rubber
stopper, apply a lubricant like glycerin to
the glass and use a twisting motion.
8. Glassware Safety
7. Do not place hot glassware in water.
Rapid cooling may make it shatter.
9. Chemical Safety
1. Wear protective goggles and a lab
apron whenever heating or pouring
hazardous chemicals.
2. Never mix chemicals together unless
you are told to do so (and then only in
the manner specified).
3. Never taste any chemicals (you should
never taste anything in the lab).
10. Chemical Safety
4. If you need to smell the odor of a
chemical, waft the fumes toward
your nose with one hand. Do not
put your nose over the container
and inhale the fumes.
5. Never pour water into a
concentrated acid. Acid
should be poured slowly into water.

caught in them.
2. Be sure your hands and your lab
area are dry before using
electrical equipment.
3. Never poke anything into
electrical outlets.
13. Electrical Safety
4. Unplug cords by pulling the plug
and not the cord.
5. Unplug all electrical equipment at
the end of the lab period.
14. Heating Safety
1. Let burners and hotplates cool
down before touching them. Test
to see if they are cool enough by
bringing the back of your hand
close to them.
2. Use tongs and/or protective gloves
to handle hot objects.
3. Never reach across an open flame
or burner.
15. Heating Safety
4. The only type of glassware that may
safely be heated is either Kimax or
Pyrex.
5. Always point the top ends of test tubes
that are being heated away from people.
6. When heating a test tube, move it
around slowly over the flame to
distribute the heat evenly.
16. Heating Safety
7. Only glassware that is thoroughly
dry should be heated.
8. Heat glassware by placing it on a
wire gauze platform on a ring stand.
Do not hold it in your hand.
17. Heating Safety
9. When lighting a burner, wait until the
striker is in place before you turn on
the gas.
10. The amount of air can be adjusted by
the air supply valve below the tube of
the burner. This regulates the flame
temperature and color.
11. Never leave a burner or hotplate
unattended.
19. First Aid
Injury: Cuts, bruises
