Accidental Release Measures
· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
· Keep combustibles (wood, paper, oil, etc.) away from spilled material.
First Aid
INGESTION: induce vomiting and follow with thorough gastric lavage, demulcents, glucose I.V., fluid therapy, and antibiotics. Tracheostomy may be lifesaving. (USCG, 1999)
General First Aid:
Firefighting Hazards
The material itself is noncombustible but it will accelerate the burning of combustible material. If the combustible material is finely divided the mixture may be explosive. Contact with liquid combustible materials may result in spontaneous ignition.
Exposure Control and Personal Protection
· Wear positive pressure self-contained breathing apparatus (SCBA).
TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
0.2 [mg/m3], as MN (inhalable fraction), 0.02 mg/m3, as Mn (respirable fraction)[German Research Foundation (DFG)]
Fire Fighting Procedures
If material on fire or involved in fire: Flood with water. Cool all affected containers with flooding quantities of water. Apply water from as far a distance as possible.
Evacuation: If fire becomes uncontrollable - consider evacuation of one-half (1/2) mile radius.
Cleanup Methods
Environmental considerations: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Add sodium bisulfite (NaHSO3).
Environmental considerations: Water spill: Add dilute caustic soda (NaOH). Add sodium bisulfite (NaHSO3). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Disposal Methods
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Spillage Disposal
Personal protection: chemical protection suit including self-contained breathing apparatus. Do NOT let this chemical enter the environment. Sweep spilled substance into covered containers. Carefully collect remainder. Then store and dispose of according to local regulations. Do NOT absorb in saw-dust or other combustible absorbents.
毒理信息
Treatment
EYES: irrigate opened eyes for several minutes under running water. INGESTION: do not induce vomiting. Rinse mouth with water (never give anything by mouth to an unconscious person). Seek immediate medical advice. SKIN: should be treated immediately by rinsing the affected parts in cold running water for at least 15 minutes, followed by thorough washing with soap and water. If necessary, the person should shower and change contaminated clothing and shoes, and then must seek medical attention. INHALATION: supply fresh air. If required provide artificial respiration.
Interactions
IN STUDIES OF RETINOTOXIC EFFECTS OF FLUORIDE IN ANIMALS, POTASSIUM PERMANGANATE HAS BEEN UTILIZED SYSTEMICALLY AS OXIDIZING AGENT TO ENHANCE TOXICITY.
4-Deoxypyridoxine (4-DPD) is a potent antagonist of Vitamin B6 coenzyme which inhibits IL-1, lymphocyte proliferation & has demonstrated that tolerance to skin grafts can be induced by administering splenic cells to pyridoxine-deficient mice. Chronic inflammation induced by dorsal injections of 200 microliters of a 1:40 saturated crystal soln of potassium permanganate (KMnO4) in mice treated or untreated with 4-DPD (400 micrograms/dose), has been investigated. After 7 days all mice developed a subcutaneous granulomatous tissue indicative of a chronic inflammatory response, at the site of injection. KMnO4-treated mice injected ip with 4-DPD (400 micrograms/dose) on 5 consecutive days (the first at the same time of induction of the granuloma) show a significant decr in size & weight of granuloma when compared to mice not treated with 4-DPD (Controls). In addition, in all mice treated with 4-DPD there was a strong inhibition of TNF alpha in serum (P < 0.01) & in supernatant fluids (P < 0.05) from minced granuloma, while IL-6 was inhibited in the supernatant fluids (P < 0.05) of minced granulomas but was not detected in the serum of treated & untreated mice. In this study we show for the first time the antiinflammatory effect of 4-DPD on chronic inflammation & the inhibitory effect of TNF & IL-6 generation in supernatant fluids from minced granulomas.
Health Effects
Manganese mainly affects the nervous system and may cause behavioral changes and other nervous system effects, which include movements that may become slow and clumsy. This combination of symptoms when sufficiently severe is referred to as “manganism”. (L228)

Toxicity Summary
Manganese is a cellular toxicant that can impair transport systems, enzyme activities, and receptor functions. It primarily targets the central nervous system, particularily the globus pallidus of the basal ganglia. It is believed that the manganese ion, Mn(II), enhances the autoxidation or turnover of various intracellular catecholamines, leading to increased production of free radicals, reactive oxygen species, and other cytotoxic metabolites, along with a depletion of cellular antioxidant defense mechanisms, leading to oxidative damage and selective destruction of dopaminergic neurons. In addition to dopamine, manganese is thought to perturbations other neurotransmitters, such as GABA and glutamate. In order to produce oxidative damage, manganese must first overwhelm the antioxidant enzyme manganese superoxide dismutase. The neurotoxicity of Mn(II) has also been linked to its ability to substitute for Ca(II) under physiological conditions. It can enter mitochondria via the calcium uniporter and inhibit mitochondrial oxidative phosphorylation. It may also inhibit the efflux of Ca(II), which can result in a loss of mitochondrial membrane integrity. Mn(II) has been shown to inhibit mitochondrial aconitase activity to a significant level, altering amino acid metabolism and cellular iron homeostasis. (L228)
Signs and Symptoms

Metabolism/Metabolites
Manganese is absorbed mainly via ingestion, but can also be inhaled. It binds to alpha-2-macroglobulin, albumin, or transferrin in the plasma and is distributed to the brain and all other mammalian tissues, though it tends to accumulate more in the liver, pancreas, and kidney. Manganese is capable of existing in a number of oxidation states and is believed to undergo changes in oxidation state within the body. Manganese oxidation state can influence tissue toxicokinetic behavior, and possibly toxicity. Manganese is excreted primarily in the faeces. (L228)
MeSH Pharmacological Classification
Substances used for the detection, identification, analysis, etc. of chemical, biological, or pathologic processes or conditions. Indicators are substances that change in physical appearance, e.g., color, at or approaching the endpoint of a chemical titration, e.g., on the passage between acidity and alkalinity. Reagents are substances used for the detection or determination of another substance by chemical or microscopical means, especially analysis. Types of reagents are precipitants, solvents, oxidizers, reducers, fluxes, and colorimetric reagents. (From Grant & Hackh's Chemical Dictionary, 5th ed, p301, p499)
Absorption, Distribution and Excretion
SYSTEMIC EFFECTS ARE NOT ... /COMMONLY SEEN/ BECAUSE OF POOR ABSORPTION.
Adult channel catfish Ictalurus punctatus were exposed to waterborne potassium permanganate for 12 wk to determine if such exposure would alter the manganese content of axial muscle or liver tissue. Continuous exposure to 0.5 mg KMnO4 or exposure to 1 or 2 mg KMnO4/L on alternate days did not cause a significant incr in manganese in axial muscle or liver tissue. The mean (|SE) concn of manganese in axial muscle of unexposed controls was 0.262 | 0.018 mg/kg (wet weight). Means of scle could be detected within groups. The mean (|SE) concn of manganese in liver tissue of controls was 1.67 | 0.09 mg/kg (wet weight). Manganese concns in liver tissue of the three exposure groups were 1.57 | 0.07 mg/kg, 1.68 | 0.08 mg/kg, and 1.58 | 0.10 mg/kg, for 0.5 (continuous), 1, or 2 mg/L (alternate days), respectively. Manganese was thought to accumulate in liver tissue, however, there were no statistically significant differences between those groups & the controls.

生产方法焙烧法氢氧化钾熔融脱水,与软锰矿粉混合,经冷却粉碎后,在240℃温度下,吸收空气中的氧,氧化焙烧缓慢地转化为锰酸钾,用水或稀溶液浸取后,压滤,配制电解液组成为:锰酸钾160~180 g/L。氢氧化钾(游离)45~60 g/L、碳酸钾<60 g/L。电解终点控制电解液中锰酸钾40~60 g/L,氢氧化钾(游离)90~110 g/L,经离心分离得高锰酸钾粗品,再经重结晶、离心分离、干燥制得高锰酸钾成品。其4KOH+2MnO2+O2→2K2MnO4+2H2O2K2MnO4+2H2O[电解]→2KMnO4+2KOH+H2↑离心分离后的母液经蒸发回收锰酸钾,经苛化回收氢氧化钾。液相氧化法氢氧化钾经预热,在200℃以上吹入富氧空气或空气,与软锰矿粉进行液相氧化反应,二氧化锰先氧化成亚锰酸钾,再进一步氧化生成锰酸钾。氢氧化钾浓度控制在60%~70%,与二氧化锰的摩尔比值为(30~60):1。锰酸钾经沉降分离,上层氢氧化钾回收,再经析晶、压滤、用电解母液溶解,并加入氢氧化钙溶液苛化,然后压滤后配制电解液进行电解,高锰酸钾粗品离心分离,再经重结晶、离心分离、干燥制得高锰酸钾成品。其2MnO2+6KOH+0.5O2→2K3MnO4+3H2O2K3MnO4+0.5O2+H2O→2K2MnO4+2KOH2K2MnO4+2H2O[电解]→2KMnO4+2KOH+H2↑离心分离后的母液,经蒸发回收锰酸钾,再经苛化回收氢氧化钾。
生产方法焙烧法-电解法将软锰矿与氢氧化钾混合成浆料,用压缩空气将物料喷入焙烧转炉,在250~300℃下氧化成锰酸钾。焙烧物用稀碱液或洗涤水浸取,经过滤、除杂质得锰酸钾。2Mn02+4KOH+O2→2K2MnO4+2H2O由于固相法传质、传热困难,操作环境差,设备庞大,能耗高,将逐渐被淘汰。锰酸钾电解氧化制取高锰酸钾的过程与液相法相同。作为食品添加剂的高锰酸钾,还需经重结晶以除去重金属和砷等。液相氧化法-电解法将软锰矿粉(0.074mm)与200℃以上80%的氢氧化钾溶液混合,并在300℃下,在第一反应器中通空气,使二氧化锰氧化成亚锰酸钾,然后溢流至第二反应器进一步氧化成锰酸钾。反应液经热过滤,用100℃、60%的KOH溶液洗涤,滤饼溶于稀碱液或洗涤水,经沉淀、分离和除杂后得锰酸钾。锰酸钾用系统内的电解终液调制成电解始液,组成如下:锰酸钾≥180g/L;碳酸钾<60/L;氢氧化钾50~60g/L。电解始液在60℃下进入钢板制成的电解槽,阳极用镍板(或镀镍钢板),阴极用铁条。阳极与阴极的面积比为1:(8~10),电流容量为1000A/m3,阳极电流密度为60~100A/m2,槽电压2.25~2.5V,板距50~100mm。锰酸钾在阳极被氧化成高锰酸钾,大部分结晶析出。冷却后经离心分离得含量为94%左右的高锰酸钾粗品,经重结晶后得含量为99.3%的高锰酸钾结晶。4MnO2+12KOH+O2→4K3MnO4+6H2O4K3Mn04+O2+2H2O→4K2MnO4↓+4KOH2K2MnO4+2H2O→2KMn04+2KOH+H2↑电解终液呈紫红色,含锰酸300~400g/L,氢氧化钾110~120g/L,以及电解中伴生的碳酸钾,经蒸发分别回收利用,部分电解终液返回系统调制电解始液。
