d.  Serious injury can result from touching apparently stationary equipment when 

using a stroboscope to `freeze´ rotary motion. 

5. Maintenance 

a.  Badly maintained equipment is a potential hazard. Ensure that a competent 

member of staff is responsible for organising maintenance and repairs on a 
planned basis. 

b.  Do not permit faulty equipment to be operated. Ensure that repairs are carried 

out competently and checked before students are permitted to operate the 
equipment. 

6. Using 

Electricity 

a.  At least once each month, check that ELCBs (RCCBs) are operating correctly 

by pressing the TEST button. The circuit breaker must trip when the button is 
pressed (failure to trip means that the operator is not protected and a repair 
must be effected by a competent electrician before the equipment or electrical 
supply is used). 

b.  Electricity is the commonest cause of accidents in the laboratory. Ensure that 

all members of staff and students respect it. 

c.  Ensure that the electrical supply has been disconnected from the equipment 

before attempting repairs or adjustments. 

d.  Water and electricity are not compatible and can cause serious injury if they 

come into contact. Never operate portable electric appliances adjacent to 
equipment involving water unless some form of constraint or barrier is 
incorporated to prevent accidental contact. 

e.  Always disconnect equipment from the electrical supply when not in use. 

7.  Avoiding fires or explosion 

a.  Ensure that the laboratory is provided with adequate fire extinguishers 

appropriate to the potential hazards. 

b.  Where inflammable liquids are used, smoking must be forbidden. Notices 

should be displayed to enforce this. 

c.  Beware since fine powders or dust can spontaneously ignite under certain 

conditions. Empty vessels having contained inflammable liquids can contain 
vapour and explode if ignited. 

d.  Bulk quantities of inflammable liquids should be stored outside the laboratory 

in accordance with local regulations. 

e.  Storage tanks on equipment should not be overfilled. All spillages should be 

immediately cleaned up, carefully disposing of any contaminated cloths etc. 
Beware of slippery floors. 

f.  When liquids giving off inflammable vapours are handled in the laboratory, the 

area should be ventilated by an ex-proof extraction system. Vents on the 
equipment should be connected to the extraction system.
