HEALTH HAZARD INFORMATION
HEALTH EFFECTS
ACUTE
SWALLOWED May irritate mouth, gullet and stomach. If ingested, decomposition may
occur in stomach leading to the production of oxygen gas. This may
cause distension of the stomach. Not toxic in concentration up to 5000
mg/kg (rat).
EYE May cause irritation
SKIN Dermatitis may occur from prolonged or repeated contact. Sensitive
individuals may develop skin irritation on prolonged or repeated contact.
INHALED Inhalation exposures highly unlikely at ambient temperatures due to the
non-volatile, non-dusting nature of the paste.
LD50 700 ppm (mouse) as benzoyl peroxide in air.
CHRONIC
FIRST AID:
SWALLOWED Immediately rinse mouth out with water. Give a glass of water to drink.
Do not induce vomiting. Lean victim forward to reduce the risk of
aspiration. Never give drink to unconscious person. Seek medical advice.
For further advice call Poisons Information Centre.
EYE Hold eyes open & flood with water for at least 15 minutes. Seek
immediate medical advice.
SKIN Remove contaminated clothing and wash area with soap and water.
Remove contaminated clothing, soak in water, then launder before re-use
Seek medical aid if irritation occurs.
INHALED Remove person to fresh air. Lay patient down and keep warm. If
breathing is shallow, apply oxygen and seek medical aid.
FIRST AID FACILITIES Where bodily contact may occur, an eye wash station & safety shower or
supply of clean water should be readily available.
ADVICE TO DOCTOR No specific treatment. Treat symptomatically.
PRECAUTIONS FOR USE
EXPOSURE STANDARDS There is no established TLV for this product mixture. Refer to each
constituent.
TWA
5 mg/ m3
Benzoyl Peroxide
ENGINEERING CONTROLS Ensure ventilation is adequate to maintain air concentrations below
exposure standards. While good natural ventilation is adequate in most
cases, local exhaust ventilation may be required. All electrical equipment
should conform to the requirements of AS3000 for location of Class 1
Zone 1

PERSONAL PROTECTION
Where ventilation is not adequate, respiratory protection may be
RESPIRATOR TYPE (AS 1716): required. Respiratory protection should comply with AS1716 and be
selected in accordance with AS 1715.
GLOVE TYPE: PVC gloves should be worn when handling. Hand protection should
comply with AS 2161
EYE PROTECTION: Full-face shield, chemical goggles or safety glasses should be worn at all
times while handling. Eye protection should comply with AS 1337 and
be selected and used in accordance with AS 1336
CLOTHING: A PVC apron, rubber or PVC boots may be required for some activities
particularly where a risk of bodily contact is present
FLAMMABILITY
FIRE HAZARDS: Flammable. Fire hazard when exposed to heat, spark or flame. Electrical
equipment should conform to the requirements of AS3000 for location
of Class 1, Zone 1.
SOURCES OF IGNITION ADVICE: Avoid all sources of ignition.
HAZCHEM CODE: 2W
SAFE HANDLING INFORMATION
STORAGE AND TRANSPORT: Store in upright original container in accordance with local statutory
requirements and applicable standards for Organic Peroxides e.g. AS
2714. Maximum product temperature 35癈. Transport in accordance
with the requirements of the current Australian Code for the Transport of
Dangerous goods by Road and Rail, the IMO Regulations for sea freight
and the IATA Regulations for airfreight.
SPILLS AND DISPOSAL: Wear personal protective clothing as recommended above. Remove all
ignition sources and ventilate area. Contain the spill with sand, earth or
inert material. Place in a suitable plastic container for waste disposal.
Dispose of in accordance with relevant local regulations. Do not empty
in drains.
UNUSUAL FIRE AND EXPLOSION Burns fiercely when ignited. Containers involved in fire can constitute
HAZARDS an explosion risk if confined. Organic peroxide provides oxygen for
combustion so simple smothering actions are not effective against
established fires. Due to possibility of re-ignition, extinguished residues
must be thoroughly cooled before approaching.
LIST OF DANGEROUS COMPOSITION OR Liberates oxygen, which will support combustion. Liberates heat,
COMBUSTION PRODUCTS noxious, flammable gases and vapour
FIRE FIGHTING RECOMMENDATION Fight fires only from safe distance. Fire 璮ighters and others exposed to
the products of combustion should wear self-contained breathing
apparatus. Prevent spillage from entering drains and watercourses. For
large fires action may need to be limited to cooling adjacent exposures
with water to prevent fire spread. Explosion hazard for product under
confinement, possibility of containers 'rocketing' and production of
fireballs.
TYPES OF EXTINGUISHER / FIRE Large quantities of fine water spray.
