Acute Health Effects

Inhalation: If inhaled, this material can irritate the throat and lungs of some persons. Inhalation of calcium oxide may produce inflammation of the respiratory passages and ulceration and perforation of the septum. Persons with impaired respiratory function, airway diseases and conditions such as emphysema or chronic bronchitis, may incur further disability if excessive concentrations of particulate are inhaled. The material has NOT been classified as "harmful by inhalation" nor has it been designated as "irritating to the respiratory system". This is because of the lack of corroborating animal or human evidence.

Skin contact:  The material can produce chemical burns following direct contact with the skin.  Skin contact is not thought to have harmful health effects, however the material may still produce health damage following entry through wounds, lesions or abrasions. Irritation caused by calcium oxide is a result of local liberation of heat and dehydration of tissues which occurs on "slaking" of the small size particles and the resulting alkalinity of the slaked product. Open cuts, abraded or irritated skin should not be exposed to this material. Solution of material in moisture on the skin, or perspiration, may markedly increase skin corrosion and accelerate tissue destruction.  Entry into the blood-stream, through, for example, cuts, abrasions or lesions, may produce systemic injury with harmful effects. Examine the skin prior to the use of the material and ensure that any external damage is suitably protected.

Ingestion: The material can produce chemical burns within the oral cavity and gastrointestinal tract following ingestion. The material has NOT been classified as "harmful by ingestion". This is because of the lack of corroborating animal or human evidence.

Eye contact: The material can produce chemical burns to the eye following direct contact. Vapours or mists may be extremely irritating. If applied to the eyes, this material causes severe eye damage

EMERGENCY AND FIRST AID PROCEDURES 

Inhalation: Move source of dust or move person to fresh air. Obtain medical attention immediately.

Skin contact: Carefully and gently brush the contaminated body surfaces in order to remove all traces of product. Wash affected area immediately with plenty of water. Remove contaminated clothing. If necessary, seek medical advice.

Ingestion: Clean mouth with water and afterwards drink plenty of water. Do NOT induce vomiting. Obtain medical attention.

Eye contact: Rinse eyes immediately with plenty of water and seek medical advice
