Important Safety Information 

Introduction 

All practical work areas and laboratories should be covered by local safety 
regulations 

which must be followed at all times

It is the responsibility of the owner to ensure that all users are made aware of 
relevant local regulations, and that the apparatus is operated in accordance with 
those regulations. If requested then Armfield can supply a typical set of standard 
laboratory safety rules, but these are guidelines only and should be modified as 
required. Supervision of users should be provided whenever appropriate. 

Your
