Sample handling warnings
Always handle all substances in accordance with the
COSHH (Control Of
Substances Hazardous to Health) regulations
(UK) or any local regula-
tions concerning sample handling safety.
Before using any substance, check the
Material Safety Data Sheets
for safe
handling information.
Use the instrument in a well ventilated room, or preferably a fume cupboard, if
fumes from the sample or dispersant are toxic or noxious.
Wear personal protective equipment as recommended by the
Material Safety
Data Sheets
if toxic or hazardous samples are being handled, particularly dur-
ing sample preparation and measurement.
Wear protective gloves when handling hazardous materials, or those that cause
skin infections or irritations.
Do not smoke during measurement procedures, particularly where inflamma-
ble samples are used or stored.
Do not eat or drink during measurement procedures, particularly where haz-
ardous samples are used or stored.
Take care when handling glass (e.g. beakers). Hazardous materials may enter a
wound caused by broken glass.
Always test a new sample or dispersant for chemical compatibility before use.
After measuring hazardous samples, scrupulously clean the system to remove
any contaminants before making another measurement.
Always 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
handling of dangerous materials.
It is important to keep a record of all hazardous substances used in the system
for protection of service and maintenance personnel.
Always 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. For rec-
ommendations see the
Materials Safety Data Sheets
.
The surfaces of the system may be permanently damaged if samples are spilt
onto them. If a spillage occurs, disconnect the system from the power supply
before scrupulously cleaning it up.
