Possible Causes Of Hazards Or Accidents In A Science Laboratory.

Practical activities and experiment are valuable in science lessons.
Doing things can be fun and it can also be dangerous, especially when the child has not yet reached the appropriate level of reasoning and awareness, or many not have fully grasped the concept of cause and effect.

These activities present some hazards to the student because in an hazardous situation human error easily results in an accident.

This is no reason, however, to stop students learning science by doing scientific activities.
Rather we should make the students/children aware of the dangers inherent in each activity and explain how to avoid them.
Thus the students/children can benefit from "learning by doing" while the possible dangers are minimized.

Practical activities and experiment may involved;
1) lighting a fire.
2) handling hot or heavy objects.
3) handling bottle, knives or other sharp implements.
4) Using caustic or flammable chemicals.
5)Catching and keeping animals.

These activities present some hazards to the students because in a hazardous situation human error easily results in an accident.

Possible Causes Of Hazards Or Accident
1) Water on a polished floor.

2) A student Pouring a liquid from a very large (Winchester) bottle.

3) Spilled acid on a bench in a position such that clothing might mob it up.

4)Liquid been poured above eye level.

5) A flammable solvent (such as acetone) being heated with a naked flame.

6) A dangerous liquid being pipettes by mouth from a vessel in which the tip of the pipette is just below the surface of the liquid.

7) Overcrowding likely to cause student to knock apparatus off the bench.

8) A jar near the edge of a cupboard where it easily fall off.

9) A test-tube stand on the edge of a bench.

10) Unsupported apparatus.

11) Using of one electric socket for many gadgets at a time.

12) Illegal electrical connection in the laboratory.
