YSI 9600 - Manual (Page 81)

SECTION 12 9600 SAFETY CONSIDERATIONS
IMPORTANT SAFETY INSTRUCTIONS!
SAVE THESE INSTRUCTIONS!
CAUTION: Operation of the YSI 9600 Nitrate Monitor requires the use of a variety of
chemicals. With one exception (elemental cadmium), the user is required to purchase these
chemicals from a vendor of their choice. Users should consult the Material Safety Data Sheets
(MSDS) supplied by these vendors for all reagents before their use. Users should ALWAYS wear
appropriate personal protective equipment including gloves and safety glasses with side shields when
handling any of these chemicals.
For proper operation of the YSI 9600, cadmium metal MUST be purchased in packaged form as the
YSI Model 9612 Cadmium Column Assembly. An MSDS for the material captured in the cadmium
column is automatically supplied to the user by YSI. To protect against potential hazards
associated with inhalation of cadmium dust, the cadmium column should be handled in a fume hood
during activation. After the reducing capacity of the cadmium column has been exhausted, the entire
sealed column should be disposed of in accordance with regulatory requirements, e.g. hazardous
waste. Users should NEVER open the cadmium column in attempts at regeneration. If the
cadmium is accidentally spilled, appropriate spill measures should be taken.
The waste generated from use of the YSI 9600 contains potentially toxic organic chemicals, but most
importantly, contains Cd
2+
that according to the USEPA is toxic and a probable human carcinogen.
Users should NEVER discharge waste from the YSI 9600 into the environment, instead retaining it in
the waste bags that are provided with the instrument. Likewise, unless specifically approved by the
local wastewater authority, users should NEVER dispose of the reaction waste into a sanitary or
storm sewer. The waste should be disposed of in accordance with regulatory requirements with an
approved waste handler.
SUMMARY
• ALWAYS wear appropriate personal protective equipment including gloves and eye protection
with side shields when handling any chemicals.
• Consult the MSDS for proper handling and disposal of all reagents
• NEVER dispose of waste solution which contains cadmium ions into a sanitary sewer without
prior approval of local wastewater authorities. It is likely that you will be required that you use
an approved waste handler for proper disposal of the waste solutions.
• NEVER dispose of used cadmium columns in your standard trash. Dispose of the used columns
through an approved waste handler.
• NEVER attempt to open a cadmium column assembly.
