FIRST AID
SKIN: EYES: INHALATION: INGESTION: Wash immediately with plenty of water. Remove contaminated clothing and do not reuse until thoroughly laundered. Seek medical help promptly. NOTE: Potassium hydroxide burns may be painless . . .!! Wash eyes with plenty of water, holding eyelids open. Seek medical assistance promptly if irritation persists. Remove from contaminated area promptly. CAUTION: Rescuer must not endanger himself! If victim’s breathing stops, administer artificial respiration and seek medical aid promptly. Give plenty of water, or milk if available, to dilute and/or neutralise product. Do not induce vomiting. Keep victim quiet. If vomiting occurs, lower victim’s head below the hips to prevent inhalation of vomited material. Seek medical help promptly. NOTE: Inadvertent inhalation of vomited material may seriously damage the lungs. The danger of this is greater than the risk of poisoning through absorption of this relatively low-­‐toxicity product. The stomach should only be emptied under medical supervision, after the installation of an airway to protect the lungs.

Leak Precaution Handling Spill dyke to control spillage and prevent environmental contamination recover free liquid with corrosion resistant pumps; neutralise residue with sodium bicarbonate (NaHCO3) or dilute acetic acid or dilute hydrochloric acid; absorb on an inert sorbent, sweep, shovel & store in closed containers for disposal; neutralised residue may be rinsed to sewer with a large volume of water 7
HANDLING & STORAGE
Store and use in a cool, dry environment, away from substances named in Part 10. Do not use or handle this product without appropriate protective clothing – water-­‐proof gauntlet-­‐style gloves, full head protection, apron, and water-­‐proof (never leather!) boots as a minimum; consider wearing a complete “bunker suit” of appropriately resistant material. Never add water to this product! To dilute, add product to water gradually, with continuous agitation. Ensure that the solution temperature remains well below the boiling point. If diluting in a plastic container, make sure that the temperature remains well below the temperature at which the plastic begins to soften! Note that spilled product is odourless and looks like water! Do not touch suspicious puddles in the vicinity of stored potassium hydroxide solution! Avoid all contact with skin and wash work clothes frequently. An eye bath and safety shower must be available close to the workplace. Avoid creating product mist. If mist forms in use, install adequate ventilation to comply with regulated limits (Part 8, below) NOTE: Corrosive burns due to potassium hydroxide may be painless, inadequately warning the victim that they are affected.

Clean Water Act Requirements: Designated as a hazardous substance under section 311(b)(2)(A) of the Federal Water Pollution Control Act and further regulated by the Clean Water Act Amendments of 1977 and 1978. These regulations apply to discharges of this substance. EPCRA EXTREMELY HAZARDOUS SUBSTANCES (40 CFR 355.30): Not regulated EPCRA SECTIONS 311/312 HAZARD CATEGORIES (40 CFR 370.10): Acute Health Hazard EPCRA SECTION 313 (40 CFR 372.65): Not Regulated Transport Methods and Regulations: No person may /transport,/ offer or accept a hazardous material for transportation in commerce unless that person is registered in conformance ... and the hazardous material is properly classed, described, packaged, marked, labeled, and in condition for shipment as required or authorized by ... /the hazardous materials regulations (49 CFR 171-­‐177)./ The International Air Transport Association (IATA) Dangerous Goods Regulations are published by the IATA Dangerous Goods Board pursuant to IATA Resolutions 618 and 619 and constitute a manual of industry carrier regulations to be followed by all IATA Member airlines when transporting hazardous materials. The International Maritime Dangerous Goods Code lays down basic principles for transporting hazardous chemicals. Detailed recommendations for individual substances and a number of recommendations for good practice are included in the classes dealing with such substances. A general index of technical names has also been compiled. This index should always be consulted when attempting to locate the appropriate procedures to be used when shipping any substance or article.

Product Name: Potassium Hydroxide, solution 6 FIFRA Requirements: Residues of potassium hydroxide are exempted from the requirement of a tolerance when used as a neutralizer in accordance with good agricultural practices as inert (or occasionally active) ingredients in pesticide formulations applied to growing crops or to raw agricultural commodities after harvest. Potassium hydroxide meeting Food Chemicals Codex specifications is exempted from the requirement of a tolerance when used as a neutralizer in accordance with good agricultural practice as inert (or occasionally active) ingredients in pesticide formulations applied to animals. As the federal pesticide law FIFRA directs, EPA is conducting a comprehensive review of older pesticides to consider their health and environmental effects and make decisions about their future use. Under this pesticide reregistration program, EPA examines health and safety data for pesticide active ingredients initially registered before November 1, 1984, and determines whether they are eligible for reregistration. In addition, all pesticides must meet the new safety standard of the Food Quality Protection Act of 1996. Pesticides for which EPA had not issued Registration Standards prior to the effective date of FIFRA, as amended in 1988, were divided into three lists based upon their potential for human exposure and other factors, with List B containing pesticides of greater concern and List D pesticides of less concern. Potassium hydroxide is found on List D. Case No: 4065; Pesticide type: fungicide, herbicide, antimicrobial; Case Status: RED Approved 09/92; OPP has made a decision that some/all uses of the pesticide are eligible for reregistration, as reflected in a Reregistration Eligibility Decision (RED) document.; Active ingredient (AI): Potassium hydroxide; AI Status: The active ingredient is no longer contained in any registered pesticide products ... "cancelled." FDA Requirements: Substance added directly to human food affirmed as generally recognized as safe (GRAS) ... when used in food at levels not to exceed current good manufacturing practice. Potassium hydroxide used as a general purpose food additive in animal drugs, feeds, and related products is generally recognized as safe when used in accordance with good manufacturing or feeding practice. 16
