Sample handling warnings
lAlways handle all substances in accordance with the COSHH (Control Of Sub-
stances Hazardous to Health) regulations (UK) or any local regulations concerning
sample handling safety.
lBefore using any substance, check the Material Safety Data Sheets for safe hand-
ling information.
lUse the instrument in a well ventilated room, or preferably within a fume cup-
board, if the fumes from the sample or dispersant are toxic or noxious.
lWear personal protective equipment as recommended by the Material Safety Data
Sheets if toxic or hazardous samples are being handled, particularly during sample
preparation and measurement.
lWear protective gloves when handling hazardous materials, or those that cause
skin infections or irritations.
lDo not smoke during measurement procedures, particularly where inflammable
samples are used or stored.
lDo not eat or drink during measurement procedures, particularly where haz-
ardous samples are used or stored.
lTake care when handling glass (e.g. microscope slides and beakers). Hazardous
materials may enter a wound caused by broken glass.
lAlways test a new sample or dispersant for chemical compatibility before use.
lAfter measuring hazardous samples, scrupulously clean the system to remove any
contaminants before making another measurement.
lAlways label samples for analysis using industry standard labelling, particularly if
they are handled by a number of staff or stored for long periods. Clearly mark any
operator hazard and associated safety precautions that are required for the hand-
ling of dangerous materials.
lKeep a record of all hazardous substances used in the system for protection of ser-
vice and maintenance personnel.
lAlways adopt responsible procedures for the disposal of waste samples. Most
local laws forbid the disposal of many chemicals in such a manner as to allow
their entry into the water system. The user is advised to seek local advice as to the
means available for disposal of chemical wastes in the area of use. Refer to the
Materials Safety Data Sheets.
lThe surfaces of the system may be permanently damaged if samples are spilt on
them. If a spillage does occur, disconnect the system from the power supply
before scrupulously cleaning up the spillage.
