3.1 Physical and Environmental
Slightly toxic to aquatic life.
A biodegradable substance. See ecological information.
3.2 Adverse human health affects
The materials are irritant to the skin and mucous membranes and are dangerous to the eyes.
If swallowed the sudden evolution of oxygen could cause internal injury - see toxicological information.
General: Medical Assistance
Symptomatic treatment and supportive therapy as indicated.
Treatment may be needed for pulmonary oedema, or respiratory failure, which may be delayed following severe over exposure.
Inhalation: Remove from exposure. Keep warm and at rest. If there is respiratory distress give oxygen. If respiration stops or shows signs of failing, apply artificial respiration. Do not use mouth to mouth ventilation. Obtain medical attention urgently.
Ingestion: Do not induce vomiting. Wash out mouth with water and give plenty of water and milk to drink, if possible prop up patient to facilitate release of gases formed in the body.
Eye Contact: Irrigate the eye thoroughly with water for at least 15 minutes, holding the eyelids apart if necessary.
Obtain medical attention.
Skin Contact: Immediately wash with plenty of water, preferably under a shower if affected area is large enough to warrant this. Remove contaminated clothing and thoroughly clean and dry all clothes before re-use.
Obtain medical attention if irritation persists or if blistering occurs.
5.1 Special Protective Equipment
Non-flammable. Decomposition may assist combustion of other flammable materials.
Toxic and therefore fire-fighters should wear breathing apparatus and appropriate protective clothing (8) - see exposure control.
5.2 Suitable Extinguishing Media
Select extinguishing medium appropriate to other materials involved in and/or to the circumstances of the fire.
Use fog equipment - in the absence of fog equipment a fine spray may be used (8).
Liberal quantities of water should be used to dilute and wash away escaping peroxide and to fight fires involving the product.
Keep stored drums cool by spraying with water from a distance.
5.3 Special Exposure Hazards
Non flammable. Decomposition may evolve oxygen and assist combustion of other flammable materials.
Decomposes exothermically, releasing a large amount of oxygen at a rate which may become explosive.
There is an explosion hazard if dilute solutions lose water by evaporation. Pressure bursts may occur due to gas evolution.
Can react violently and explosively when in contact with organic materials, oxidising agents, heavy metals and dust contamination. See stability and reactivity.
6.1 Methods for Cleaning
Small and large spills: dilute - may be washed to drain with large quantities of water (8).
Dilute to less than 1% w/w and put to drain with plenty of water.
See disposal considerations and environmental precautions.
Wash the site of the spillage with plenty of water and detergent.
Dispose of hazardous waste in accordance with waste disposal and water authority regulations.
6.2 Personal precautions
Avoid contact with the product. Ventilate the area to dispel airborne concentrations.
Full body protective clothing with breathing apparatus should be worn when dealing with spillage (8) - see exposure control.
Remove all sources of ignition.
6.3 Environmental Precautions
If size of spillage warrants and has contaminated water courses, drains or vegetation - advise appropriate authorities.
Evacuate personnel from the area.
Handling: Exposure by inhalation or skin contact should be minimised by good industrial hygiene practice.
Wear appropriate protective clothing - see exposure control.
Safety showers and eyebaths should be available in areas where accidental exposure is possible.
Ensure adequate ventilation to keep the airborne concentration as low as possible. Extinguish ignition sources - no smoking.
Care should be taken when opening containers as pressure may have built up during storage.
Avoid contact with combustible, flammable or corrosive products.
Scoops, containers and implements used for handing the product must be free of contamination.
Storage: Store in a cool, dry, well ventilated area, away from incompatible chemicals or materials - see stability and reactivity.Do not store containers on wooden pallets.
Avoid exposure to sunlight, heat and ignition sources or contamination by combustion dust.
Store on concrete flooring that can be swilled and drained.
Large quantities must be stored in vented containers fitted with valves to release pressure build up.
For bulk storage, store in passivated stainless steel (Grade 304L or 306L) or HOPE containers.
Containers must be clean and free of organic residues - see stability and reactivity.
Do not store in mild steel or any other metal containers.
Wear PVC or rubber gloves.
Wear close fitting goggles/face shield.
Eyebaths should be provided at places where accidental exposure may be possible.
Wear acid resistant footwear and impervious apron.
Showers should be provided at places where accidental exposure may be possible.
Occupational exposure limits assigned by HSE(1) and ACGIH(2):-
OES-LTEL = 1ppm (1.5mgm-3), OES-STEL = 2ppm (3mgm-3) HSE(1)
In the event where significant exposure is possible (eg In dealing with spillage, fire or exposure to vapour and /or toxic fumes).
Wear self-contained breathing apparatus - see stability and reactivity.
| Appearance | Clear, colourless, mobile liquid. |
| Odour | Pungent, characteristic odour. |
10.1 Conditions to avoid
Avoid exposure to heat sources, high temperatures, pressure build-up and contamination by dusts or combustible materials.
Do not allow product to dry out - see fire fighting measures.
10.2 Materials to avoid
Reacts violently with readily oxidisable organic materials, acids, alkalis, reducing agents and other oxidisers.
Catalytically decomposed by heavy metals and their salts, enzymes and contaminants such as dirt and rust.
May react vigorously with flammable liquids and gases and other combustible materials.
10.3 Hazardous Decomposition Products
Decomposes liberating oxygen which assists the burning of combustible materials.
Decomposition is highly exothermic. Contamination by an oxidisable or an organic material presents an explosion hazard.
Acute Effects:
Liquid and mist cause severe irritation and corrosion to skin, eyes, respiratory and digestive tracts.
Corrosive to eyes and may cause corneal damage.
Causes temporary bleaching of the skin. Prolonged contact may cause blistering.
May be absorbed systematically by inhalation or ingestion after significant exposure.
May cause coughing, sore throat, nausea, lung congestion and possibly pulmonary oedema or unconsciousness.
After ingestion, sudden evolution of oxygen may cause injury by acute distension of the stomach and oesophagus.
Ingestion of large amounts may result in severe abdominal pain, vomiting, diarrhoea, convulsions and collapse.
Chronic Effects:
Ingestion may cause haematemists, oesophageal and gastric perforation.
13.1 Disposal Dangers
Treat as for spillages. Wear appropriate protective clothing - see accidental release measures.
Care should be taken to ensure accidental mixing with acids or reducing agents, in drains, is avoided.
There is a potential explosion hazard if spilt product contaminates finely divided organic material.
Do not attempt to neutralise with strong acids.
Neutralisation generates much heat.
13.2 Disposal Methods
Large and small spillage’s:- dilute. May be washed to drain with large quantities of water (8).
Dispose of any hazardous waste in accordance with waste disposal or water authority regulations.
