Important Safety Information 

g.  Students should not be allowed to prepare mixtures for analysis or other 

purpose without competent supervision. 

8.  Handling poisons, corrosive or toxic materials 

a.  Certain liquids essential to the operation of equipment, for example mercury, 

are poisonous or can give off poisonous vapours. Wear appropriate protective 
clothing when handling such substances. Clean up any spillage immediately 
and ventilate areas thoroughly using extraction equipment. Beware of slippery 
floors. 

b.  Do not allow food to be brought into or consumed in the laboratory. Never use 

chemical beakers as drinking vessels. 

c.  Where poisonous vapours are involved, smoking must be forbidden. Notices 

should be displayed to enforce this. 

d.  Poisons and very toxic materials must be kept in a locked cupboard or store 

and checked regularly. Use of such substances should be supervised. 

e.  When diluting concentrated acids and alkalis, the acid or alkali should be 

added slowly to water while stirring. The reverse should never be attempted. 

9.  Avoiding cuts and burns 

a.  Take care when handling sharp edged components. Do not exert undue force 

on glass or fragile items. 

b.  Hot surfaces cannot, in most cases, be totally shielded and can produce 

severe burns even when not `visibly hot´. Use common sense and think which 
parts of the equipment are likely to be hot. 

10. Eye protection 

a.  Goggles must be worn whenever there is a risk to the eyes. Risk may arise 

from powders, liquid splashes, vapours or splinters. Beware of debris from 
fast moving air streams. Alkaline solutions are particularly dangerous to the 
eyes. 

b.  Never look directly at a strong source of light such as a laser or Xenon arc 

lamp. Ensure that equipment using such a source is positioned so that 
passers-by cannot accidentally view the source or reflected ray. 

c.  Facilities for eye irrigation should always be available. 

11. Ear protection 

a.  Ear protectors must be worn when operating noisy equipment. 

12. Clothing 

a.  Suitable clothing should be worn in the laboratory. Loose garments can cause 

serious injury if caught in rotating machinery. Ties, rings on fingers etc. should 
be removed in these situations. 

b.  Additional protective clothing should be available for all members of staff and 

students as appropriate.
