Section VI - Accidental Release Measures
Sweep up and use as fertilizer if non-contaminated.
Small Spill:
Large Spill: Collect with appropriate equipment. If on a hard surface, sweep up residue with brooms. If on soil, remove
and collect the top 5cm of soil.
Potash is highly soluble and can be quickly diluted below the toxic level by relatively large amounts of
Release Notes:
water. Potash which has entered a small non permanent pond should be removed by pumping the pond
dry. If spill could potentially enter any waterway, including intermittent dry creeks, contact the local author-
ities. If in the U.S., contact the US COAST GUARD NATIONAL RESPONSE CENTER toll free number
800-424-8802. In case of accident or road spill notify: CHEMTREC IN USA at 800-424-9300; CANUTEC
in Canada at 613-996-6666 CHEMTREC in other countries at(International code)+1-703-527-3887.
See Section XIII for disposal information and Section XV for regulatory requirements. Large and small
Comments:
spills may have a broad definition depending on the user's handling system. Therefore, the spill cate-
gory must be defined at the point of release by technically qualified personnel.
Section VII - Handling and Storage
Local exhaust to reduce dust concentrations below recommended levels.
Ventilation:
Avoid generating dust by excessive or unnecessary movement.
Handling:
Storage: Store in a dry location. Avoid contact with aluminum or carbon steel to minimize corrosion.
Section VIII - Exposure Controls/ Personal Protection
May be necessary to minimize dust levels.
Engineering
Controls:
Personal Protection:
Eye Protection: Use tight-fitting safety goggles in areas of high dust concentration.
Protective Clothing: Gloves, long sleeve shirts and long pants. Launder work clothing regularly.
Respiratory NIOSH approved dust respirators until engineering controls are implemented.
