Write types of hazards. How general laboratory safety measures help keep safe from hazards?
Answer:
Types of hazards:
Chemical Hazards
A chemistry laboratory presents the greatest combination of potential hazards. However, careful attention to techniques
and the avoidance of known dangers can help to make this area as safe as any other.
Biological Hazards
Laboratories used for teaching biology present the teacher with a wide range of insidious hazards. Besides hazards specific
to biological work, dangers can arise from the presence in the laboratory of animals, micro-organisms, and plants. Becausea possible hazards often does not make itself obvious until several days after infection, biological work must be treated as
a special case.
Radiation Hazards
Each year seems to bring more and more items of equipment into the teaching laboratory that only a short while ago were
confined to research laboratories.
Fire HazardsMost books dealing with fires and fire prevention make the point that for a fire to break out three things must be present
-these being represented by the mnemonic fire triangle.
General Laboratory Safety and Techniques
Systems Checking
The Head of Department in a school or college has the responsibility to see that the laboratories are safe for his staff and
students. Nothing should be taken for granted in this respect and schools and college staff should, on a regular and
methodical basis, check all laboratory services – gas, power, water, drainage, and fume extraction, where appropriate.
Use of Posters
Published posters, aimed at drawing people’s attention to unsafe practices, are frequently grossly misused. If you are lucky
enough to have a set of such posters, do not make the mistake of exhibiting them all at once.
General
Quite often, staff store items of equipment in such a way that frequently used item are in the most convenient position for
regular access. This has a number of advantages but on hazard can result if staff is not on their guard. When storing items
on shelving, etc., always make sure that heavy items are at ground level, very close to it. Each year, staff and students
have accidents as a result of lifting rarely use, but heavy items from a high shelf, which they have reached by standing on
a stool. In addition, a shelf holding more than one line of bottles is dangerous when items are lifted from the back line.
