POTENTIAL HEALTH EFFECTS

ACUTE HEALTH EFFECTS

SWALLOWED

  The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion.  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

  The material can produce chemical burns to the eye following direct contact. Vapors or mists may be extremely irritating.  If applied to the eyes, this material causes severe eye damage.  Eye contact with organic peroxides can cause clouding, redness, swelling and burns of the eye on prolonged contact.  

SKIN

  The material can produce chemical burns following direct contactwith the skin.  Bare unprotected skin should not be exposed to this material.  All organic peroxides are irritating to the skin and if allowed to remain on the skin, may produce inflammation; some are allergenic.  

INHALED

  If inhaled, this material can irritate the throat andlungs of some persons.  Not normally a hazard due to non-volatile nature of product.  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

  Principal routes of exposure are usually by skin contact/eye contact with the material and inhalation of vapor/spray mist.  Persistent exposure over a long period of time to peroxides produces allergic skin reactions ( redness and scaling of the skin ) and asthmatic wheezing.
