Important Safety Information 

b.  It is irresponsible and dangerous to misuse equipment or ignore instructions, 

regulations or warnings. 

c.  Do not exceed specified maximum operating conditions (eg. temperature, 

pressure, speed etc). 

2. Installation 

a.  Use lifting tackle where possible to install heavy equipment. Where manual 

lifting is necessary beware of strained backs and crushed toes. Get help from 
an assistant if necessary. Wear safety shoes where appropriate. 

b.  Extreme care should be exercised to avoid damage to the equipment during 

handling and unpacking. When using slings to lift equipment, ensure that the 
slings are attached to structural framework and do not foul adjacent pipework, 
glassware etc. When using fork lift trucks, position the forks beneath 
structural framework ensuring that the forks do not foul adjacent pipework, 
glassware etc. Damage may go unseen during commissioning creating a 
potential hazard to subsequent operators. 

c.  Where special foundations are required follow the instructions provided and 

do not improvise. Locate heavy equipment at low level. 

d.  Equipment involving inflammable or corrosive liquids should be sited in a 

containment area or bund with a capacity 50% greater than the maximum 
equipment contents. 

e.  Ensure that all services are compatible with the equipment and that 

independent isolators are always provided and labelled. Use reliable 
connections in all instances, do not improvise. 

f.  Ensure that all equipment is reliably earthed and connected to an electrical 

supply at the correct voltage. The electrical supply must incorporate a 
Residual Current Device (RCD) (alternatively called an Earth Leakage Circuit 
Breaker - ELCB) to protect the operator from severe electric shock in the 
event of misuse or accident. 

g.  Potential hazards should always be the first consideration when deciding on a 

suitable location for equipment. Leave sufficient space between equipment 
and between walls and equipment. 

3. Commissioning 

a.  Ensure that equipment is commissioned and checked by a competent 

member of staff before permitting students to operate it. 

4. Operation 

a.  Ensure that students are fully aware of the potential hazards when operating 

equipment. 

b.  Students should be supervised by a competent member of staff at all times 

when in the laboratory. No one should operate equipment alone. Do not leave 
equipment running unattended. 

c.  Do not allow students to derive their own experimental procedures unless 

they are competent to do so.
