EMERGENCY OVERVIEW

RISK

Contact with combustible material may cause fire.
Irritating to eyes.

Repeated exposure may cause skin dryness and cracking.
Very toxic to aquatic organisms, may cause long- term adverse effects in the
aquatic environment.

POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  Although ingestion is not thought to produce harmful effects, the material may still be damaging to the health of the individual following ingestion, especially where pre-  existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally based on doses producing mortality (death) rather than those producing morbidity (disease, ill-health). Gastrointestinal tract discomfort may produce nausea and vomiting. In an occupational setting however, ingestion of insignificant quantities is not thought to be cause for concern.  Considered an unlikely route of entry in commercial/industrial environments.  Ingestion of organic peroxides may produce nausea, vomiting, abnormal pain, stupor, bluish discoloration of skin and mucous membranes. Inflammation of the heart muscle may also occur.  

EYE

  This material can cause eye irritation and damage in some persons.  Eye contact with organic peroxides can cause clouding, redness, swelling and burns of the eye on prolonged contact.  

SKIN

  Skin contact with the material may damage the health of the individual; systemic effects may result following absorption.  The material is not thought to be a skin irritant (as classified using animal models). Temporary discomfort, however, may result from prolonged dermal exposures. Good hygiene practice requires that exposure be kept to a minimum and that suitable gloves be used in an occupational setting.  Toxic effects may result from skin absorption.  Bare unprotected skin should not be exposed to this material.  Sensitization may result in allergic dermatitis responses includingrash, itching, hives or swelling of extremities.  Sensitization reactions may appear suddenly after repeatedsymptom free exposures.  All organic peroxides are irritating to the skin and if allowed to remain on the skin, may produce inflammation; some are allergenic.  

INHALED

  There is some evidence to suggest that this material, if inhaled, can irritate the throat and lungs of some persons.  Although inhalation is not thought to produce harmful effects, the material may still produce health damage, especially where pre-existing organ (e.g. liver, kidney) damage is evident. Present definitions of harmful or toxic substances are generally confined to doses producing mortality (death) rather than those producing morbidity (disease, ill-  health).  Not normally a hazard due to non-volatile nature of product.  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 edema.  Inhalation of vapor may aggravate a pre-existing respiratory condition such as asthma, bronchitis, emphysema.  Decomposition products may be highly toxic if inhaled.  The inhalation of organic peroxide dusts or vapors can produce throat and lung irritation and cause an asthma-like effect. Over-exposure can cause tears, salivation, lethargy, slow breathing, breathing difficulties, headache, weakness, tremor, stupor and swelling of the lung.  

CHRONIC HEALTH EFFECTS

  Skin contact with the material is more likely to cause a sensitization reaction in some persons compared to the general population.  Ample evidence exists, from results in experimentation, that developmental disorders are directly caused by human exposure to the material.  

  Principal routes of exposure are usually by skin contact inhalation of vapor.  Persistent exposure over a long period of time to peroxides produces allergic skin reactions ( redness and scaling of the skin ) and asthmatic wheezing.  Diluted forms of benzoyl peroxide when used as acne and skin bleach  treatment results in 1-2% of these applications showing allergic responses  and / or sensitisation.  Ingestion of material results in abdominal pain, cyanosis and severe  depression.
