3. Wear gloves and goggles when handling the glassware. Carefully rinse
the glassware several times with water to decontaminate it.
4. Wipe the exterior surfaces of the Digesdahl apparatus (heating mantle,
electrical controls, etc.) and other laboratory surfaces several times
with a damp or wet cloth or paper towel.
5. Do not rinse or spray the apparatus directly; this could damage
the equipment.
6. Discard any paper towels or cloths in an appropriate manner; they may
be contaminated from the sample or chemical residues.
Hazardous waste disposal regulations were promulgated in accordance
with the Resource Conservation and Recovery Act (RCRA) and are given
in Title 40 Code of Federal Regulations (CFR), parts 260 to 280. Waste
must be managed and disposed of in accordance with federal, state and
local regulations. Refer to Section VIII of the Hach Material Safety Data
Sheet that come with reagents for basic disposal information on Hach
Products. The USEPA maintains a hotline number for questions regarding
RCRA. It is 1-800-424-9346
This manual does not contain all the regulatory requirements. Additional
state and local laws may apply to waste that you generate. It is each
generator's responsibility to know which regulations apply to them and to
adhere to these regulations. Check with your environmental compliance
staff for specific instructions.
