· For advice, contact a Poisons Information Centre or a doctor at once.
· Urgent hospital treatment is likely to be needed.
· If swallowed do NOT induce vomiting.
· If vomiting occurs, lean patient forward or place on left side (head-down position, if possible) to maintain open airway and prevent aspiration.
· Observe the patient carefully.
· Never give liquid to a person showing signs of being sleepy or with reduced awareness; i.e. becoming unconscious.
· Give water to rinse out mouth, then provide liquid slowly and as much as casualty can comfortably drink.
· Transport to hospital or doctor without delay.


■ If this product comes in contact with the eyes:
· Immediately hold eyelids apart and flush the eye continuously with running water.
· Ensure complete irrigation of the eye by keeping eyelids apart and away from eye and moving the eyelids by occasionally lifting the upper and lower lids.
· Continue flushing until advised to stop by the Poisons Information Centre or a doctor, or for at least 15 minutes.
· Transport to hospital or doctor without delay.
· Removal of contact lenses after an eye injury should only be undertaken by skilled personnel.


■ If skin or hair contact occurs:
· Immediately flush body and clothes with large amounts of water, using safety shower if available.
· Quickly remove all contaminated clothing, including footwear.
· Wash skin and hair with running water. Continue flushing with water until advised to stop by the Poisons Information Centre.
· Transport to hospital, or doctor.


· If fumes or combustion products are inhaled remove from contaminated area.
· Lay patient down. Keep warm and rested.
· Prostheses such as false teeth, which may block airway, should be removed, where possible, prior to initiating first aid procedures.
· Apply artificial respiration if not breathing, preferably with a demand valve resuscitator, bag-valve mask device, or pocket mask as trained. Perform CPR if necessary.
· Transport to hospital, or doctor.
· Inhalation of vapours or aerosols (mists, fumes) may cause lung oedema.
· Corrosive substances may cause lung damage (e.g. lung oedema, fluid in the lungs).
· As this reaction may be delayed up to 24 hours after exposure, affected individuals need complete rest (preferably in semi-recumbent posture) and must be kept under medical observation even if no symptoms are (yet) manifested.
· Before any such manifestation, the administration of a spray containing a dexamethasone derivative or beclomethasone derivative may be considered.
This must definitely be left to a doctor or person authorised by him/her.


■ Hydrogen peroxide at moderate concentrations (5% or more) is a strong oxidant.
· Direct contact with the eye is likely to cause corneal damage especially if not washed immediately. Careful ophthalmologic evaluation is recommended and the
possibility of local corticosteroid therapy should be considered.
· Because of the likelihood of systemic effects attempts at evacuating the stomach via emesis induction or gastric lavage should be avoided.
· There is remote possibility, however, that a nasogastric or orogastric tube may be required for the reduction of severe distension due to gas formation"
Fisher Scientific MSDS.
Depending on the degree of exposure, periodic medical examination is indicated. The symptoms of lung oedema often do not manifest until a few hours have passed and
they are aggravated by physical effort. Rest and medical observation is therefore essential. Immediate administration of an appropriate spray, by a doctor or a
person authorised by him/her should be considered.

From IERG (Canada/Australia)
Isolation Distance 25 metres
Downwind Protection Distance 100 metres
IERG Number 31


1 PROTECTIVE ACTION ZONE is defined as the area in which people are at risk of harmful exposure. This zone assumes that random changes in wind direction confines the
vapour plume to an area within 30 degrees on either side of the predominant wind direction, resulting in a crosswind protective action distance equal to the downwind
protective action distance.
2 PROTECTIVE ACTIONS should be initiated to the extent possible, beginning with those closest to the spill and working away from the site in the downwind direction.
Within the protective action zone a level of vapour concentration may exist resulting in nearly all unprotected persons becoming incapacitated and unable to take
protective action and/or incurring serious or irreversible health effects.
3 INITIAL ISOLATION ZONE is determined as an area, including upwind of the incident, within which a high probability of localised wind reversal may expose nearly all
persons without appropriate protection to life- threatening concentrations of the material.
4 SMALL SPILLS involve a leaking package of 200 litres (55 US gallons) or less, such as a drum (jerrican or box with inner containers). Larger packages leaking less
than 200 litres and compressed gas leaking from a small cylinder are also considered " small spills" .
LARGE SPILLS involve many small leaking packages or a leaking package of greater than 200 litres, such as a cargo tank, portable tank or a " one- tonne" compressed
gas cylinder.
5 Guide 143 is taken from the US DOT emergency response guide book.
6 IERG information is derived from CANUTEC - Transport Canada.


The maximum airborne concentration below which it is believed that nearly all individuals could be exposed for up to one hour WITHOUT experiencing or developing
life- threatening health effects is:
hydrogen peroxide 100ppm
irreversible or other serious effects or symptoms which could impair an individual' s ability to take protective action is:
hydrogen peroxide 50ppm
other than mild, transient adverse effects without perceiving a clearly defined odour is:
hydrogen peroxide 10ppm

■ Hydrogen peroxide
· is a powerful oxidiser
· contamination or heat may cause self accelerating exothermic decomposition with oxygen gas and steam release - this may generate dangerous pressures - steam explosion.
· reacts dangerously with rust, dust, dirt, iron, copper, acids, metals and salts, organic material.
· is unstable if heated. (e.g): one volume of 70% hydrogen peroxide solution decomposes to produce 300 volumes of oxygen gas.
· in presence of a strong initiating source may be explosively reactive
· concentrated or pure material can generate heat and decompose spontaneously; can ignite or explode when heated, shocked, contaminated; or if placed in a basic (>7) environment, especially in the presence of metal ions
· mixtures with combustible materials may result in spontaneous combustion or may be impact- or heat- sensitive - evaporation or drying on towels or mop may cause a fire.
· reacts violently with reducing agents, alcohols, ammonia, carboxylic acids, acetic acid, cobalt oxides, copper(II) chloride, ethers, metal powder, permanganates, acetone, benzenesulfonic anhydride, 1,1-dimethylhydrazine, dimethylphenylphosphine, gadolinium hydroxide, hydrogen selenide, iron oxides, lithium tetrahydroaluminate, magnesium tetrahydroaluminate, manganese(II) oxide, mercury oxide, methyl hydrazine, nickel monoxide, nitrogenous bases, osmium tetraoxide, alpha-phenylselenoketones, phosphorus, phosphorus(V) oxide, quinoline, tetrahydrothiophene, tin(II) chloride, thiodiglycol, thiophane, tin(II) chloride, unsaturated organic compounds, readily oxidisable and combustible materials; avoid contact with combustibles including lubricants and graphite
· reacts with cobalt, copper and its alloys, chromium, iridium, iron, lead, manganese, Monel, osmium, palladium, platinum, gold, silver, zinc, and other catalytic metals, metal oxides and salts - avoid metallic bowls and stirrers.
· violent catalytic decomposition will occur in contact with certain metals such as iron, copper, chromium, brass, bronze, lead, silver, manganese or their salts.
· forms unstable and possible explosive materials with acetic anhydride, aconitic acid, aniline, carboxylic acids, 1,4-diazabicyclo[2,2,2]octane, diphenyl diselenide, ethyl acetate, glycols, ketene, ketones, triethyltin hydroperoxide, 1,3,5-trioxane, vinyl acetate.
· is incompatible with mercurous chloride
· decomposes in presence of alkalis and even ordinary dust or rust
· decomposes slowly at ordinary temperatures and builds up pressure in a closed container; the rate of decomposition doubles for each 10 deg C rise in temperature and decomposition becomes self-sustaining at 141 deg. C
· contact with rough surfaces can cause decomposition
· attacks and may ignite some plastics, rubber and coatings.
· Inorganic reducing agents react with oxidizing agents to generate heat and products that may be flammable, combustible, or otherwise reactive. Their reactions with oxidizing agents may be violent.
· Incidents involving interaction of active oxidants and reducing agents, either by design or accident, are usually very energetic and examples of so-called redox reactions.
· Avoid any contamination of this material as it is very reactive and any contamination is potentially hazardous.
· Inorganic oxidising agents can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air).
· Organic compounds in general have some reducing power and can in principle react with compounds in this class. Actual reactivity varies greatly with the identity of the organic compound.
· Inorganic oxidising agents can react violently with active metals, cyanides, esters, and thiocyanates.
· Avoid strong bases.
· Avoid storage with reducing agents.

· Safety glasses with unperforated side shields may be used where continuous eye protection is desirable, as in laboratories; spectacles are not sufficient where
complete eye protection is needed such as when handling bulk- quantities, where there is a danger of splashing, or if the material may be under pressure
· Chemical goggles.whenever there is a danger of the material coming in contact with the eyes; goggles must be properly fitted
· Full face shield (20 cm, 8 in minimum) may be required for supplementary but never for primary protection of eyes; these afford face protection.
· Alternatively a gas mask may replace splash goggles and face shields.
· Contact lenses may pose a special hazard; soft contact lenses may absorb and concentrate irritants. A written policy document, describing the wearing of lens or
restrictions on use, should be created for each workplace or task. This should include a review of lens absorption and adsorption for the class of chemicals in use
and an account of injury experience. Medical and first- aid personnel should be trained in their removal and suitable equipment should be readily available. In the
event of chemical exposure, begin eye irrigation immediately and remove contact lens as soon as practicable. Lens should be removed at the first signs of eye redness
or irritation - lens should be removed in a clean environment only after workers have washed hands thoroughly. [CDC NIOSH Current Intelligence Bulletin 59], [AS/NZS
1336 or national equivalent].


· Elbow length PVC gloves.
· When handling corrosive liquids, wear trousers or overalls outside of boots, to avoid spills entering boots.
Suitability and durability of glove type is dependent on usage. Important factors in the selection of gloves include:
· frequency and duration of contact,
· chemical resistance of glove material,
· glove thickness and
· dexterity
Select gloves tested to a relevant standard (e.g. Europe EN 374, US F739, AS/NZS 2161.1 or national equivalent).
· When prolonged or frequently repeated contact may occur, a glove with a protection class of 5 or higher (breakthrough time greater than 240 minutes according to EN
374, AS/NZS 2161.10.1 or national equivalent) is recommended.
· When only brief contact is expected, a glove with a protection class of 3 or higher (breakthrough time greater than 60 minutes according to EN 374, AS/NZS
2161.10.1 or national equivalent) is recommended.
· Contaminated gloves should be replaced.
Gloves must only be worn on clean hands. After using gloves, hands should be washed and dried thoroughly. Application of a non- perfumed moisturiser is recommended.
· Where hydrogen peroxide exposure may occur do NOT wear PVA gloves.
· DO NOT use leather or cotton gloves, leather shoes as spill may cause fire.
· Care: Effects may be delayed.
· Hand cream offers no protection for hydrogen peroxide and should not be used.


· Overalls.
· PVC Apron.
· PVC protective suit may be required if exposure severe.
· Eyewash unit.
· Ensure there is ready access to a safety shower.
· Some plastic personal protective equipment (PPE) (e.g. gloves, aprons, overshoes) are not recommended as they may produce static electricity.
· For large scale or continuous use wear tight- weave non- static clothing (no metallic fasteners, cuffs or pockets), non sparking safety footwear.


■ Glove selection is based on a modified presentation of the:
" Forsberg Clothing Performance Index" .
The effect(s) of the following substance(s) are taken into account in the
computer- generated selection: hydrogen peroxide
■ Protective Material CPI *.
____________________________________________ ■ * CPI - Chemwatch Performance Index A: Best Selection B: Satisfactory; may degrade after 4 hours continuous immersion C: Poor to Dangerous Choice for other than short term immersion NOTE: As a series of factors will influence the actual performance of the glove, a final selection must be based on detailed observation. - * Where the glove is to be used on a short term, casual or infrequent basis, factors such as " feel" or convenience (e.g. disposability), may dictate a choice of gloves which might otherwise be unsuitable following long- term or frequent use. A qualified practitioner should be consulted.


•Type B Filter of sufficient capacity. (AS/NZS 1716 & 1715, EN 143:2000 & 149:2001, ANSI Z88 or national equivalent)
■ Selection of the Class and Type of respirator will depend upon the level of breathing zone contaminant and the chemical nature of the contaminant. Protection

■ Explosive reaction may result from the interaction of strong oxidisers and organics.
· Do NOT use strong oxidising agents in fume hoods designed for other purposes. Identify fume hoods used for strong oxidising agents with large warning signs.
· Provide exhaust ventilation and room supply air in accordance with appropriate Standard.
· Utilise local exhaust ventilation within the hood to minimise condensation of vapours inside the hood.
· Locate all utility controls outside the hood.
· Materials of construction for this type of hood and ductwork must be non- reactive, preferably acid resistant and relatively impervious. AVOID ORGANIC MATERIALS
unless known to be safe. Stainless steel type 316 with welded joints is preferred. Unplasticised polyvinyl chloride or an inorganic ceramic coating such as porcelain
is acceptable.
· Ease of cleanliness is paramount. Use stainless steel with accessible rounded corners and all- welded construction.
· The work surface should be water- tight with a minimum of 1 cm (1/2" ) dished front and sides and an integral trough at the rear to collect the washdown water.
· Design washdown facilities into the hood and ductwork. Use daily or more often to thoroughly clean water- soluble oxidisers from the exhaust system surfaces.
· Each hood should have an individual exhaust system. Slope horizontal runs to drain. Avoid sharp turns.
· Construct the hood and ductwork to allow easy visual inspection.
· Where required use a high efficiency (greater than 80%) wet collector constructed for water- soluble oxidiser service. Locate as close to the hood as possible to
minimise the accumulation of the oxidiser in the exhaust duct.
· Use only a metallic fan protected by an inorganic coating (preferably acid- resistant), or an air ejector.
· Lubricate the fan with a fluorocarbon type grease.
· Locate the fan outside the building.
· The exhaust discharge must terminate out- of- doors preferably using a vertical discharge cap which extends well above the roof eddy zone. Air contaminants
generated in the workplace possess varying " escape" velocities which, in turn, determine the " capture velocities" of fresh circulating air required to effectively
remove the contaminant.
Type of Determinant: Air Speed:
solvent, vapours, degreasing etc., evaporating from tank (in still air). 0.25- 0.5 m/s (50-100 f/min.)
aerosols, fumes from pouring operations, intermittent container filling, low speed conveyer transfers, welding, spray drift, plating acid fumes, pickling (released at low velocity into zone of active generation) 0.5- 1 m/s (100-200 f/min.)
direct spray, spray painting in shallow booths, drum filling, conveyer loading, crusher dusts, gas discharge (active generation into zone of rapid air motion) 1- 2.5 m/s (200-500 f/min.)
grinding, abrasive blasting, tumbling, high speed wheel generated dusts (released at high initial velocity into zone of very high rapid air motion). 2.5- 10 m/s (500-2000 f/min.)
Within each range the appropriate value depends on:
Lower end of the range Upper end of the range
1: Room air currents minimal or favourable to capture 1: Disturbing room air currents
2: Contaminants of high toxicity 2: Contaminants of low toxicity or of nuisance value only.
3: Intermittent, low production. 3: High production, heavy use
4: Large hood or large air mass in motion 4: Small hood-local control only
Simple theory shows that air velocity falls rapidly with distance away from the opening of a simple extraction pipe. Velocity generally decreases with the square of distance from the extraction point (in simple cases). Therefore the air speed at the extraction point should be adjusted, accordingly, after reference to distance from the contaminating source. The air velocity at the extraction fan, for example, should be a minimum of 1- 2 m/s (200- 400 f/min.) for extraction of solvents generated in a tank 2 meters distant from the extraction point. Other mechanical considerations, producing performance deficits within the extraction apparatus, make it essential that theoretical air velocities are multiplied by factors of 10 or more when extraction systems are installed or used.



Clear, colourless to light blue, water- like liquid, odourless (or with a characteristic slightly acidic odour). Pure hydrogen peroxide is a transient material

· Presence of incompatible materials.
· Product is considered stable under normal handling conditions.
· Prolonged exposure to heat.
· Hazardous polymerisation will not occur.
Solutions of hydrogen peroxide slowly decompose, releasing oxygen, and so are often stabilised by the addition of acetanilide, etc.

For incompatible materials - refer to Section 7 - Handling and Storage.





■ Accidental ingestion of the material may be harmful; animal experiments indicate that ingestion of less than 150 gram may be fatal or may produce serious damage to
the health of the individual.
The material can produce severe chemical burns within the oral cavity and gastrointestinal tract following ingestion.
Hydrogen peroxide may cause blistering and bleeding from the throat and stomach. When swallowed, it may release large quantities of oxygen which could hyper- distend
the stomach and gut and may cause internal bleeding, mouth and throat burns and rupture of the gut. There may also be fever, nausea, foaming at the mouth, vomiting,
chest and stomach pain, loss of consciousness, and movement disorders and death. Large amounts can also cause cessation of breath, dizziness, headache, tremors
weakness or numbness in the extremities and convulsions. Hydrogen peroxide concentrate is corrosive and must not be taken undiluted.


■ The material can produce severe chemical burns to the eye following direct contact. Vapours or mists may be extremely irritating.
If applied to the eyes, this material causes severe eye damage.
Hydrogen peroxide concentrations above 10% are corrosive to the eye and may cause corneal ulceration even days after exposure.


■ The material can produce severe chemical burns following direct contactwith the skin.
Skin contact is not thought to produce harmful health effects (as classified under EC Directives using animal models). Systemic harm, however, has been identified
following exposure of animals by at least one other route and the material may still produce health damage following entry through wounds, lesions or abrasions. Good
hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.
Skin contact will result in rapid drying, bleaching, leading to chemical burns on prolonged contact.
Open cuts, abraded or irritated skin should not be exposed to this material.
Entry into the blood- stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use
of the material and ensure that any external damage is suitably protected.
Hydrogen peroxide is used topically as dental gel and to clean minor wounds. It may cause dose dependent effect on the skin including bleaching, blistering,
reddening and corrosion ( at >50% concentration).


■ Inhalation of vapours or aerosols (mists, fumes), generated by the material during the course of normal handling, may be harmful.
Inhalation of quantities of liquid mist may be extremely hazardous, even lethal due to spasm, extreme irritation of larynx and bronchi, chemical pneumonitis and
pulmonary oedema.
Inhalation of excessive levels of mist or vapour of hydrogen peroxide may result in damage to the various body systems and produce multi- systemic effects made worse
by its poor warning nature. This may lead to extreme irritation of the nose and chest, cough, discomfort, shortness of breath and inflammation of the nose and


■ There has been some concern that this material can cause cancer or mutations but there is not enough data to make an assessment.
Substance accumulation, in the human body, may occur and may cause some concern following repeated or long- term occupational exposure.
Hydrogen peroxide as a human food additive is generally regarded as safe when used in certain limitations. In experimental animals, oral administration of hydrogen
peroxide causes dental, liver, kidney, stomach, and intestinal damage. Inhalation exposure to hydrogen peroxide caused skin irritation and sneezing in dogs, and high
mortality in mice.
Hydrogen peroxide added to food is affirmed to be generally regarded as safe (GRAS) by the U.S. FDA when used to treat certain foods in specified limitations [FDA 21
CFR 184.1366 (4/1/93)]. Hydrogen peroxide may be used as a component of articles for use in packaging, handling, transporting, or holding food in accordance with
prescribed conditions [FDA 21 CFR 175.105 (4/1/93)].
Dose- related growth retardation, induction of dental caries, and pathological changes in the periodontium were observed in young male rats receiving 1.5% hydrogen
peroxide as their drinking fluid (equivalent to approximately 2.1 g/kg/day)2 for 8 weeks .
Effects observed in mice treated for 35 weeks with 0.15% hydrogen peroxide as their drinking fluid (equivalent to approximately 0.29 g/kg/day)3 included degeneration
of hepatic and renal tubular epithelial tissues, necrosis, inflammation, irregularities of tissue structure of the stomach wall, and hypertrophy of the small
intestine wall. Concentrations in excess of 1% (equivalent to approximately 1.9 g/kg/day)4 resulted in pronounced weight loss and death within two weeks. In a
sequential study of mice treated with 0.4% hydrogen peroxide in drinking water (equivalent to approximately 0.76 g/kg/day)5 , gastric erosion was observed at 30 days
and was present consistently throughout the 108 week study period.
Dogs exposed 6 hours/day, 5 days/week for 6 months at an average vapour concentration of 7 ppm (9.73 mg/3 ) of 90% hydrogen peroxide, developed skin irritation,
sneezing, lacrimation, and bleaching of the hair. Autopsy disclosed pulmonary irritation and greatly thickened skin, but no hair follicle destruction. No significant
changes in blood or urinary parameters were observed .
Following eight 6- hour exposures to hydrogen peroxide at a concentration of 79 mg/m3 (56.88 ppm), 7/9 mice died. Following exposure to hydrogen peroxide at 93 mg/m3
, 6 hours/day, 5 days/week for 30 exposures, 1/10 rats died.
Repeated or prolonged exposure to acids may result in the erosion of teeth, swelling and/or ulceration of mouth lining. Irritation of airways to lung, with cough,
and inflammation of lung tissue often occurs. Chronic exposure may inflame the skin or conjunctiva.

■ Asthma- like symptoms may continue for months or even years after exposure to the material ceases. This may be due to a non- allergenic condition known as reactive airways dysfunction syndrome (RADS) which can occur following exposure to high levels of highly irritating compound. Key criteria for the diagnosis of RADS include the absence of preceding respiratory disease, in a non- atopic individual, with abrupt onset of persistent asthma- like symptoms within minutes to hours of a documented exposure to the irritant. A reversible airflow pattern, on spirometry, with the presence of moderate to severe bronchial hyperreactivity on methacholine challenge testing and the lack of minimal lymphocytic inflammation, without eosinophilia, have also been included in the criteria for diagnosis of RADS. RADS (or asthma) following an irritating inhalation is an infrequent disorder with rates related to the concentration of and duration of exposure to the irritating substance. Industrial bronchitis, on the other hand, is a disorder that occurs as result of exposure due to high concentrations of irritating substance (often particulate in nature) and is completely reversible after exposure ceases. The disorder is characterised by dyspnea, cough and mucus production. Exposure to hydrogen peroxide via the skin or oral route can produce toxic effects. Animal studies have shown evidence of damage to the kidney, gut, thymus and liver. Stomach and intestinal lesions including benign and malignant cancers have been observed in mice. It may produce genetic and developmental defects but no reproductive toxicity was reported in mice. The substance is classified by IARC as Group 3: NOT classifiable as to its carcinogenicity to humans. Evidence of carcinogenicity may be inadequate or limited in animal testing.

■ For hydrogen peroxide: log Kow: - 1.36 Environmental fate: Hydrogen peroxide is a naturally occurring substance (typical background concentrations < 1 - 30 g/l). Almost all cells with the exception of anaerobic bacteria produce it in their metabolism. Hydrogen peroxide is a reactive substance in the presence of other substances, elements, radiation, materials and can be degraded by micro- organisms or higher organisms. Air: Hydrogen peroxide may be removed from the atmosphere by photolysis giving rise to hydroxyl radicals, by reaction with hydroxyl radicals, or by heterogenous loss processes such as rain- out. Significantly higher hydrogen peroxide concentrations are found in polluted atmospheres as compared with clean air. These concentrations are believed to arise from photochemically- initiated oxidation of reactive hydrocarbons. Under severe smog conditions, daytime levels of hydrogen peroxide as high as 0.18 ppm have been reported, but atmospheric night- time levels of 2- 5 ppb did not correlate to smog intensity. Soil: No information was found in the secondary sources searched regarding the transformation or persistence of hydrogen peroxide in soil, however, solutions of hydrogen peroxide gradually deteriorate. Water: Hydrogen peroxide is a naturally occurring substance. Surface water concentrations of hydrogen peroxide have been found to vary between 51- 231 mg/L, increasing both with exposure to sunlight and the presence of dissolved organic matter. Hydrogen peroxide degrades by various mechanisms, including chemical reduction and enzymatic (catalase and peroxidase) decomposition by algae, zooplankton, and bacteria. Microorganisms, especially bacteria, account for the majority of degradation, significantly more than all other chemical and biological mechanisms. The rate at which hydrogen peroxide decomposes in natural water can vary from a few minutes to more than a week, depending on numerous chemical, biological, and physical factors. Hydrogen peroxide is rapidly degraded in a biological waste water treatment plant. Hydrogen peroxide adsorbs poorly to sediment particles and is rapidly degraded, thus accumulation in the sediment is also not expected Hydrogen peroxide (log Kow < - 1) is an inorganic substance and therefore shows little potential to bioaccumulate. Ecotoxicity: Fish LC50 (96 h): catfish 37.4 mg/l Fish LC50 (24 h): mackerel 89 mg/l; chameleon gobi 155 mg/l Zebra mussel LC50 (28 h) 30 mg/l; (228 h): 12 mg/l Ecotoxicity data show that microorganisms (i.e., bacteria, algae) and zooplankton present in aquatic ecosystems are generally less tolerant of hydrogen peroxide exposure than are fish or other vertebrates. Effects of short- term exposures on sensitive bacteria and invertebrates (e.g., Daphnia pulex) have been observed at concentrations in the low mg/L (ppm) range, while effects on sensitive algae have been reported at levels less than 1.0 mg/L. Algae are the most sensitive species for hydrogen peroxide. The algal EC50 of hydrogen peroxide was 1.6- 5 mg/l, while the NOEC was 0.1 mg/l. In a 21- d continuous exposure study on Daphnia magna, the chronic no observable effect concentration (NOEC) for reproduction was 0.63 mg/L and the NOEC for mortality was 1.25 mg/L. In chronic toxicity studies with invertebrates (zebra mussels) and hydrogen peroxide shows an NOEC of 2 mg/l. The PNEC of hydrogen peroxide is equal to 10 ug/l. Risk mitigation is needed to ensure that use of hydrogen peroxide will not adversely impact aquatic life. An acute water quality criterion or " benchmark" has been determined. For hydrogen peroxide, the acute benchmark is 0.7 mg/L. This value was calculated using the extensive toxicity database for hydrogen peroxide and procedures in U.S. Environmental Protection Agency guidance for deriving numerical national water quality criteria. The use of hydrogen peroxide in intensive aquaculture in finfish (at up to 100 mg/L for 60 minutes) and finfish eggs (at up to 1, 000 mg/L for 15 minutes) is not expected to have a significant impact on the environment. DO NOT discharge into sewer or waterways. WATER:

· Containers may still present a chemical hazard/ danger when empty.
· Return to supplier for reuse/ recycling if possible.
· If container can not be cleaned sufficiently well to ensure that residuals do not remain or if the container cannot be used to store the same product, then puncture containers, to prevent re-use, and bury at an authorised landfill.
· Where possible retain label warnings and MSDS and observe all notices pertaining to the product.
Legislation addressing waste disposal requirements may differ by country, state and/ or territory. Each user must refer to laws operating in their area. In some areas, certain wastes must be tracked.
A Hierarchy of Controls seems to be common - the user should investigate:
· Reduction
· Reuse
· Recycling
· Disposal (if all else fails)
This material may be recycled if unused, or if it has not been contaminated so as to make it unsuitable for its intended use. If it has been contaminated, it may be possible to reclaim the product by filtration, distillation or some other means. Shelf life considerations should also be applied in making decisions of this type. Note that properties of a material may change in use, and recycling or reuse may not always be appropriate.
· DO NOT allow wash water from cleaning or process equipment to enter drains.
· It may be necessary to collect all wash water for treatment before disposal.
· In all cases disposal to sewer may be subject to local laws and regulations and these should be considered first.
· Where in doubt contact the responsible authority.
For small quantities of oxidising agent:
· Cautiously acidify a 3% solution to pH 2 with sulfuric acid.
· Gradually add a 50% excess of sodium bisulfite solution with stirring.
· Add a further 10% sodium bisulfite.
· If no further reaction occurs (as indicated by a rise in temperature) cautiously add more acid.
· Recycle wherever possible.
· Consult manufacturer for recycling options or consult local or regional waste management authority for disposal if no suitable treatment or disposal facility can be identified.
· Treat and neutralise at an approved treatment plant. Treatment should involve: Neutralisation followed by: burial in a land-fill specifically licenced to accept chemical and / or pharmaceutical wastes or Incineration in a licenced apparatus (after admixture with suitable combustible material)
· Decontaminate empty containers. Observe all label safeguards until containers are cleaned and destroyed.
