Appropriate respirators and other PPE may be require d. If possible , stem t he spill and dam spilled liquid with sand or earth. Avoid discharge to the environment and if it occurs i mmediately notify the appropriate federal, state and local authorities. Dispose of the spilled material in accordance with all ap plicable regulations, and subsequently decontaminate all surfaces, clothing and other articles with plenty of water.  For any spills, DO NOT mop up with paper, clot h or other combustible material.  Due to rapid decomposition, hydrogen peroxide will not accu mulate in the environment.

While necessary for sterilization and disinfection , hydrogen peroxide is a highly corrosive chemical. Kn ow the facts for process management and safety. Uses of Hydrogen Peroxide Biocide: Healthcare, aseptic packaging, bottling B leach: pulp & paper , bleaching agent for food Oxidizer: Rocket Propulsion 1 Chemical Properties (H 2 O 2 )  Hydrogen peroxide is a str ong oxidizing agent, and primary irritant but a weak acid (pK a = 11.62 ).  No odor at low concentrations, acid - like odor at high concentrations reported by some people.  M ol. Wt 34.01 g/mol, CAS 7722 - 84 - 1 , MP - 0.43 o C, BP 152 o C . Note : may decompose violently if traces of impurities are present. 1  Its oxidation potential makes it a very efficient biocide, and bleaching agent . This high reactivity also means that it rapidly breaks down in the environment to benign ox ygen and water making it environmentally friendly but hazardous to anyone exposed to it.  Incompatibilities & Reactivities : Oxidizable materials, iron, copper, brass, bronze, chromium, zinc, lead, silver, manganese. Contact with combustible material may re sult in SPONTANEOUS combustion. 2 Microbiocidal Activity Hydrogen peroxide has been shown to be effective against all forms of microorganisms, including dormant forms with known high resistance such as bacterial spores and protozoal cysts, and also infecti ous proteins such as prions depending on the specific use of the chemical. 3 1 Merck Index, 12 th Edition 2 http://www.cdc.gov/niosh/npg/npgd0335.html 3 The Use of Hydrogen Peroxide for Disinfection and Sterilization Applications Pe roxides (2014). Gerald McDonnell; Publ. Wiley, online: 28 APR 2014 Hazard Summary 4  Liquid contact can severely irritate and burn the skin and damage the eyes  Inhalation of vapor can irritate nose and throat and lungs and higher exposures may cau se a pulmonary edema (a medical emergency caused by build up of fluids in the lungs).  Exposure can cause headaches, dizziness, nausea and vomiting.  Hydrogen peroxide is a mutagen – handle it as a possible carcinogen. ACGIH classifies it as a ‘confirmed ani mal carcinogen with unknown relevance to humans.’ 5  Hydrogen peroxide is a reactive and dangerous explosion hazard, and a strong oxidizer, which may enhance combustion of other substances.  Symptoms : irritation eyes, nose, throat; corneal ulcer; erythema (sk in redness), vesiculation skin; bleaching hair . 6 Mutagen, corrosive, reactive, oxidizer, poisonous gases are produced in fire, containers may explode in fire. 7 NFPA R ating with concentration) 8 H 2 O 2 Conc. wt.% Health Flammability Reactivity < 8 0 0 0 8 - 20 1 0 1 20 - 52 3 0 1 52 - 91 3 0 2 > 91 3 0 3 4 http://nj.gov/health/eoh/rtkweb/documents/fs/1015.pdf 5 2014 Guide to Occupational Exposure values, ACGIH 6 http://www.cdc.gov/niosh/npg/npgd0335.html 7 http://nj.gov/health/eoh/rtkwe b/documents/fs/1015.pdf 8 http://www.h2o2.com/technical - library/default.aspx?pid=76&name=Hazard - Classes Oxidizer Class w ith Concentration 9 Concentration Example s <8% , ( Non - Hazardous ) Contact lens sterilizer (2%) , Over - the - counter H 2 O 2 (3%) , Liquid detergent bleach (5%) , Hair bleach (7.5%) 8% - 28% ( Clas s 1 ) E.g.

An oxidizer that causes a severe increase in the burning rate of combustible materials with which it comes into contact. Class 4. An oxidizer that can undergo an explosive reaction due to contamination or exposure to thermal or physical shock and that causes a severe increase in the burning rate of combustible materials with which it comes into contact. 10 NIOSH RTECS #: MX0900000 11 RTECS Compound Description: Tumorigen , Drug , Mutagen , Human Data , Hormone , Primary Irritant Exposure Limits  US OSHA PEL 1 ppm ( 8 Hr TWA) ; 12  Hawaii and 13 Washington State 14 3 ppm short term exposure limit [STEL], ( 15 min TWA) .  UK HSE WEL 1ppm ( 8 hr TWA ) , 2ppm STEL ( 15 min TWA) 15  ACGIH STEL TLV 1 ppm, ( 8 Hr TWA) 16  NIOSH REL 1 ppm (hr TWA) 17 , IDLH 75 ppm. 18 9 http://www.h2o2.com/technical - library/default.aspx?pid=76&name=Hazard - Classes 10 http://codesonline.nfpa.org/a/c.ref/ID00001135745/chapter 11 http:/ /www.cdc.gov/niosh - rtecs/MXDBBA0.html 12 29 CFR 1910.1000 Tbl Z - 1 13 http://labor.hawaii.gov/hiosh/files/2012/12/12 - 60 - General - Safety - Health - Requiremen ts.pdf , retrieved 1/15/2013 14 http://apps.leg.wa.gov/wac/default.aspx?cite=296 - 841 - 20025 15 EH40/2005 Workplace exposure limits (publ. 2011) 16 2014 Guide to Occupational Exposure Values, ACGIH 17 http://www.cdc.gov/niosh/npg/npgd0335.html 18 http://www.cdc.gov/niosh/idlh/intridl4.html
