Personal Precautions, Protective Equipment and Emergency Procedures
General measures:

Wear proper protective equipment and avoid contact with skin andinhalation of vapor. Conduct operations from upwind and evacuatepeople downwind.

:

Attention should be given to avoid discharge of spilled productinto rivers and resulting environmental damage. When diluting
spill with large amounts of water, discharge of untreatedwastewater into the environment must be avoided.

13. Disposal considerations: Add the chemical in a large amount of calcium hydroxide
solution gradually to precipitate. Filter the precipitation
and bury in a landfill site approved for hazardous waste
disposal.

Ecological waste information

Drain the filtrate after pH control.
Or entrust approved waste disposal companies with thedisposal.
The pH of the neutralization should be above 8.5. The
precipitation does not form completely below pH 8.5.
Comply with applicable laws and regulations when draining
wastewater.
As unreacted toxic gas may be emitted at the disposal work,
wear appropriate protective equipment. Even a small amount of
the gas has the toxicity.
Contaminated container andpackaging: In case of disposal of empty bottles, dispose bottles after
removing the content thoroughly.
