EC No. : 231-765-0 EC Index no. : 008-003-00-9

Bandon,
Co. Cork. Ireland.
Emergency Telephone No.: (023) 43466
2. COMPOSITION
Solution of Hydrogen Peroxide in water.
3. HAZARDS IDENTIFICATION
Main Hazard - Oxidising. Contact with combustibles may cause fire. Decomposes yielding
oxygen that supports combustion of organic matters and can cause overpressure if
confined. It is corrosive to eyes, nose, throat and lungs. May cause irreversible tissue
damage to the eyes, including blindness. It may also cause skin irritation.
4. FIRST AID MEASURES
Inhalation : Remove to fresh air, keep patient warm and administer oxygen if
necessary. Symptoms may include coughing, sneezing, damage to
the nasal or respiratory tract. If respiration stops or shows signs of
failing apply artificial respiration. Obtain medical attention urgently.
Skin Contact : Drench immediately with copious amounts of water. Remove
contaminated clothing and continue washing the affected areas.
Completely decontaminate clothing and shoes before reuse or
disposal. If irritation persists obtain medical attention.
Eye Contact : Immediately flood the eye with clean water for at least 15 minutes
ensuring the corners and under both eyelids are adequately flushed.

Directors: William Holland & Eileen Holland. Tel: +353 23 43466
Web: http://www.acornwater.ie, Email: info@acornwater.ie Fax: +353 23 43467
Obtain medical attention for all cases where contact with the eye
occurs.
Ingestion : Do not induce vomiting. Provided the patient is conscious, wash
out the mouth with water and give about 500 mls of water to drink.
Obtain medical attention urgently.
Note to physician: Hydrogen peroxide at these concentrations is a strong oxidant. Direct
contact with the eye is likely to cause corneal damage especially if
not washed immediately. Careful opthalmological evaluation is
recommended and the possibility of local corticosteroid therapy
should be considered. Because of the likelihood of corrosive effects on
the gastrointestinal tract after ingestion and the unlikelihood of
systemic effects, attempts at evacuating the stomach via emesis
induction of 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.
5. FIRE FIGHTING MEASURES
The material is non-combustible, but on decomposition releases oxygen which may intensify
fire. Suitable extinguishing media include water, water fog or quenching foam. Unsuitable
substances include carbon dioxide and quenching powder. Oxygen is released during
decomposition and there is a risk of overpressure and burst due to decomposition in
confined spaces and pipes. In case of fire wear respiratory protective equipment
independent of surrounding air and chemical protective suit.
6. ACCIDENTAL RELEASE MEASURES
Refer to points No.8 and No.13 for information on personal protective equipment and
disposal.
Small Spillages : Dilute and wash away with large amounts of water
taking care to avoid splashing.
Large Spillages : Keep unauthorised personnel away from the immediate
area. If appropriate inform the police, fire brigade, local
authority and E.P.A. Contain the spillage using sand or earth for
subsequent disposal. Do not use: textiles, saw dust,
combustible materials. Keep away from drains and prevent from
entering watercourse. (i.e. rivers, canals etc.).
Never return spilled product into its original container for re-use
(risk of decomposition).

7. HANDLING AND STORAGE
7.1 Handling : Contact with eyes and skin must be avoided. Refer to
point No. 8 for information on personal protective equipment.
An emergency shower, eyewash station and water supply
should be provided at locations where accidental exposure is
foreseeable, e.g. at filling/discharge points. Never return
unused hydrogen peroxide to original container. Empty drums
should be triple rinsed before discarding.
Materials used in handling should be compatible with the
product and advice should be sought in selection.
7.2 Storage : Only use containers which are specifically permitted for
hydrogen peroxide, and/or for transport, storage and tank
installations. Suitable materials include vanadium steel (1.4571
or 1.4541), aluminium (min. 99.5%), aluminium magnesium
alloys, plastics (PVC, rigid PVC, polyethylene, polypropylene),
glass or ceramics. Store drums in cool areas out of direct
sunlight and use adequate venting devices on all containers. Do
not confine product in unvented vessels or between closed
valves as there is a risk of overpressure and bursting due to
decomposition in confined spaces. Do not store with alkalis,
reducing agents, metallic salts, combustible products and
organic solvents (danger of explosion).
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
Direct contact with the skin must be prevented. Ventilation should be provided to minimise
the release of hydrogen peroxide vapours and mists into the work enviornment. The usual
precautionary measures for dealing with chemicals should be observed and wear suitable
personal protective equipment when appropriate.
1ml/m3 = 1.5mg/m3
Occupational exposure limits OES (GB)
1ml/m3 =1.4 mg/m3
TLV/TWA (USA)
Respiratory Protection : Breathing apparatus should be worn if concentrations exceed
the OEL due to inadequate ventilation of the work area.
Hand Protection : PVC, neoprene or rubber gloves.
Eye Protection : Close fitting chemical goggles or full-face visor if appropriate.
Skin Protection : Cotton or PVC overalls; PVC or rubber boots. Avoid cotton
wool and leather.

10. STABILITY AND REACTIVITY
Hydrogen peroxide is an oxidising agent and is very reactive. It is stable at room
temperature, but there is a risk of decomposition when exposed to heat. When coming in
contact with the product, impurities, decomposition catalysts, incompatible substances,
combustible substances, may lead to self-accelerated, exothermic decomposition and the
formation of oxygen. Mixtures with combustible materials (e.g. solvents) can have explosive
properties. Impurities to be avoided include metal ions, metallic salts, metals, alkalis,
hydrochloric acid, reducing agents, combustible substances and organic solvents.
11. TOXICOLOGICAL INFORMATION
Short Term Effects of Over Exposure:
Inhalation : Inhalation of vapours/ aerosols may lead to severe irritation of
the respiratory tract and may cause inflammation and
pulmonary oedema. Symptoms may occur with delay. LC50 >
0.17 mg/l (rat) (50% H2O2).
Skin Contact : Causes burns. By time of exposure increase locally erythema or
severe irritation (white colouration), even to blistering (burning
may occur). Skin absorption LD50 > 2000 mg/kg (rabbit) (35%
H202).
Eye Contact : May cause irreversible tissue damage to the eyes, including
blindness. Symptoms may occur with delay.
Ingestion : Causes severe damage to the mucous membranes or deeper
tissue of the mouth, throat, oesophagus and stomach and death may
result from subsequent penetration into vital areas. Rapid liberation
of oxygen may cause gastric distension and bleeding and may lead to

severe damage to internal organs, in particular , if larger quantities of
product are swallowed. LD50 = 1193 mg/kg (rat) (35% H2O2).
Long Term Effects Of Over Exposure: Acute effects predominate.
Chronic Effects Of Over Exposure: There are reports of limited evidence of
carcinogenicity of hydrogen peroxide to mice administered high concentrations in their
drinking water (IARC Monograph 36,1985). However , the international agency for research
on cancer concluded that hydrogen peroxide could not be classified as to its carcinogenicity
to humans (Group II carcinogen).
12. ECOLOGICAL INFORMATION
Environmental Fate
Hydrogen peroxide is regarded as generally not endangering water courses. Under
environmental conditions rapid decomposition takes place forming oxygen and water or it is
reduced, generally exerting no significant adverse effects on the environment.
Persistence & Degradation
Hydrogen peroxide half-life in fresh water ranges from 8 hours to 20 days, in air from 10-20
hrs and in soils from minutes to hours depending upon microbiological activity and metal
contaminants.
Eco-toxicity
Aquatic toxicity : (all data related to Hydrogen peroxide 100%).
Acute fish toxicity: LC50 (96h) approx. 27 mg/l, various species
Acute toxicity to crustaceans: LC50 (48h) approx. 5 mg/l, various species
Effects on effluent treatment
Reduction & decomposition to water and oxygen.
13. DISPOSAL INFORMATION
Small quantities of material can be disposed of by diluting with a large amount of water and
allowing the hydrogen peroxide to decompose and running to drain. For large quantities a
specialist waste disposal firm should be used.
