Laboratory Safety - For Science Teachers

PREFACE

The world is getting more complex and it is getting harder to answer questions in

a simple way. Experimental designs based on hands on activities have been gained

much more importance on science education which is combined with technology,

engineering and math. According to the developments and discoveries in science

field, new experimental designs, elements and chemical reactions have been involved

in practical applications. Today’s technological progress has authorized us

to gather and endorse information with an increasing speed; it has also permitted

us to make experiments more like real-world science.

This guideline can be helpful to support safer working areas in laboratories for

not only science teachers it can be useful also for supervisors, administrators and

the other science curriculum directors. One of the priorities is to have an understanding

of a science teachers’ mission and school science safety regulations and

also make teachers and authorities aware about the high frequency of school science

laboratory accidents.Laboratories are visibly more dangerous areas than the

class environment at schools. For an example, students can break glassware materials

and use the tools with incorrect interactions. These accidents sometimes may

cause simple cuts or injury but may be sometimes it may cause severe burns and

serious injuries. Therefore it needs to have some arrangements and educational

interventions that can minimize the damages by conscious interventions against

such accidents. By the issues have been involved in this guidelines will help to

create a safer learning environment. Transformation of a classroom to a laboratory,

safe storage of chemicals, planning the science activities in the laboratory,

electrical and fire safety, ventilation and use of fume cupboards, use of eye wash

and safety shower, use of heat sources, emergency exit doors, seismic movements,

distribution of science curriculum subjects in terms of laboratory use, order and

cleaning in laboratory and pictograms are the relevant topics that will help a science

teacher to have more awareness on safety.

The manual about “ Laboratory Safety for Science Teachers” created with the

support of sources believed to be reliable and known as the bests in the field. The

aim is to generate a general source for science teachers for daily practices at school

laboratories. It is intended to decrease the accidental risks according to the usage

of school science laboratories.
