2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Harmful if swallowed. Effects may include gastritis and possibly progressing to necrosis or hemorrage with large overexposures. Eye
Eye contact may cause eye corrosion or ulceration. Severe eye damage may result if not immediately treated. Skin
Skin contact with aqueous solutions or the dry powder upon contact with moisture or perspirations may cause skin burns or ulceration; temporary body hair loss may occur in contacted areas. Skin contact with the product may cause allergic skin reactions in sensitive individuals. Human patch tests with the product diluted in water at concentrations up to 150 ppm did not cause allergic skin reactions. Inhaled
Inhalation may cause nose blleds and irritation of the upper respiratory passages with cougihng and discomfort. 2.2 Health Effects - Chronic
None known. None of the components present in this material at concentrations equal to or greater than 0.1% are listed by IARC, OSHA, NTP or ACGIH as a carcinogen. Individuals with preexisting diseases of the skin or gastrointestinal tract may have increased susceptibility to the toxicity of excessive expsoures.
2.3 First Aid
Swallowed
If swallowed, DO NOT induce vomiting. Immediately give 2 glasses of water. Never give anything by mouth to an unconscious person. Call a physician.
Eye
Irrigate with copious amounts of water for 15 minutes. Seek medical assistance if symptoms persists.
Skin
Wash affected areas with copious quantites of water. In case of contact immediately flush skin with plenty of water for at least 15 minutes, while removing contaminated clothing and shoes. Call a physician. Wash contaminated clothing.
Inhaled
If inhaled, immediately remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Call a physician.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
Treat symptomatically based on judgement of doctor and individual reactions of patient.
2.6 Toxicity Data
Oral-rat LD50 = 2,000 mg/kg Inhalation-rat 4-hour LC50 = > 5mg/L Skin absorption-rabbit LD50 = > 11,000 mg/kg A blend of oxone monopersulfate and anhydrous sodium carbonate caused skin coorosion in tests on animals. Single inhalation exposures produced nonspecific effects such as weight loss and irritation. Repeated inhalation produced eye irritation and reversible corneal damage. By ingestion, the administration of large single doses produced nonspecific effects such as weight loss and irritation as well as gastric ulceration, necrosis, and haemorrhage. The compound does not produce genetic damage in bacterial cell cultures.
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Worksafe TWA : none established (particulates : 10 mg/m3) Worksafe STEL : none established AEL (DuPont) : 1 mg/m3 - 8hr TWA TLV (ACGIH) : none established PEL (OSHA) : particulates not otherwise regulated. 15 mg/m3-8hr TWA - total dust 5 mg/m3-8hr TWA - respirable dust
3.2 Engineering Controls
Keep containers in a well ventilated room. Use sufficient ventilation to keep employee exposure below recommended limits.
3.3 Personal Protection
Wearing of the following personal protective equipment is recommended. Chemical goggles (conforming to AS1336 and AS1337). Additionally wear a face shield where the possibility exists for face contact due to splashing or spraying or material. PVC, neoprene or nitrile rubber glvoes (conforming to AS2161). Appropriate protective clothing (conforming to AS2919). Where there is potential for airbourne exposures in excess of applicable limits, wear approved respiratory protection. Respirators should comply with AS1716 or an equivalent and should be used in accordance with AS1715. Use a positive air supplied respirator if there is any potential for an uncontrolled release, exposure levels are not known, or any other circumstance where air-purifying respirators may not provide adequate protection.
3.4 Flammability
Non combustible. Non flammable. Will release oxygen on heating in fire. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Keep container tightly closed. Do not store or consume food, drink or tobacco in areas where they may become contaminated with this material. Store in a cool dry, well ventilated area away from heat sources such as light fixtures or space heaters. Pallets of 25kg bags can be stacked. Leave open space on all sides of each pallet to provide ventilation. See local fire codes for allowablre limits. Bulk bags should be stored on pallets; if stsacked use pyramid style, no more than 2 pallets high. Closely stacked bags should not exceed 4 ft (1.2m) cude. Keep packages dry. Do not store with combustible materials.
4.2 Packaging / Labelling UN No. 3260 Class 8 Sub Risk None Allocated Hazchem Code 2X Pack Group III EPG No. 37 Shipping Name CORROSIVE SOLID ACIDIC INORGANIC NOS (POT.PEROXYMONOSULFATE) Hazard CORROSIVE
Risk Phrases R8 Contact with combustible material may cause fire. R34 Causes burns.
Safety Phrases S26 In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. S36/37/39 Wear suitable protective clothing, gloves and eye/face protection. S45 In case of accident or if you feel unwell, seek medical advice immediately (show the label whenever possible).
4.3 Spills and Disposal
Spills
Clean up personnel should wear suitable protective clothing including respiratory protection. Prevent contamination of drains and waterways.
Use absorbent (soil or sand, sawdust, inert material, vermiculite). Collect and seal in properly labelled drums for disposal. Wash area down with excess water. Clean up using a shovel. Contain all spills within a bund. Sweep up. Flush area with low pressure water.
Disposal
If approved, flush to sewer to waste treatment plant. Large quantities should be neutralised with soda ash. Treatment, storage, transportation, and disposal of waste must be in accordance with applicable Federal, State and Local regulatory requirements.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Does not ignite. Non combustible. Storage of large masses of this material can trap heat and lead to ignition of paper bags. Grinding or intensive mixing may cause ignition of oxidisable material present. The material is stable. The mixture of this material with compounds containing halidesor active halogens can cause release of the respective halogen if moisture is present. For example, mixture with sodium dichloroisocyanuride or with sodium chloride can cause release of chlorine gas; mixture with cyanides can cause release of hydrogen cyanide gas; and heavy metal salts such as those of cobalt, nickel, copper or manganese cause the evolution of oxygen. Polymerisation will not occur. Decomposition releases oxygen gas.
Extinguishing Media
Fire-fighters should wear full protective clothing including self-contained breathing apparatus. Use an extinguishing media for combustible materials in the area. Avoid breathing decomposition products. 5 OTHER INFORMATION
Other Information
Avoid contaminating waterways. Aquatic toxicity: Potassium sulfate - 96hr Tlm (bluegill sunfish): 3500 mg/l. Magnesium carbonate - 96 hr LC50 (species unidentified): >1000 ppm.
