Causes severe burns.
Risk of serious damage to eyes.
Very toxic by inhalation, in contact with skin and if swallowed.
Harmful to aquatic organisms, may cause long- term adverse effects in the
aquatic environment.
Severely toxic effects may result from the accidental ingestion of the material; animal experiments indicate that ingestion of less than 5 gram may be fatal or may produce serious damage to the health of the individual. The material can produce severe chemical burns within the oral cavity and gastrointestinal tract following ingestion. The material is considered to be harmful by all exposure routes.
The material can produce severe 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 is extremely painful and may cause rapid corneal damage. The material may produce moderate eye irritation leading to inflammation. Repeated or prolonged exposure to irritants may produce conjunctivitis. The vapour when concentrated has pronounced eye irritation effects and this gives some warning of high vapour concentrations. If eye irritation occurs seek to reduce exposure with available control measures, or evacuate area.
Skin contact with the material may produce severely toxic effects; systemic effects may result following absorption and these may be fatal. The material can produce severe chemical burns following direct contactwith the skin. Bare unprotected skin should not be exposed to this material. Solutions of hydrofluoric acid, as dilute as 2%, may cause severe skinburns. Fluorides are easily absorbed through the skin and cause death of soft tissue and erode bone. Healing is delayed and death of tissue may continue to spread beneath skin. The material may cause skin irritation after prolonged or repeated exposure and may produce on contact skin redness, swelling, the production of vesicles, scaling and thickening of the skin. Solution of material in moisture on the skin, or perspiration, mayincrease irritant effects.
If inhaled, this material can irritate the throat andlungs of some persons. Acute effects of fluoride inhalation include irritation of nose and throat, coughing and chest discomfort. A single acute over-exposure may even cause nose bleed. Pre-existing respiratory conditions such as emphysema, bronchitis may be aggravated by exposure. Occupational asthma may result from exposure. The material may produce respiratory tract irritation, and result in damage to the lung including reduced lung function.
Considered toxic by all exposure routes. Principal routes of exposure are usually by skin contact, eye contact with the material and inhalation of vapor. Hydrogen fluoride easily penetrates the skin and causes destruction and corrosion of the bone and underlying tissue. Ingestion causes severe pains and burns in the mouth and throat and blood calcium levels are dangerously reduced. Symptoms include spasm and twitching of the muscles, high fever, convulsions and general extreme pain. Inhalation may cause corrosion of the throat, nose and lungs, leading to severe inflammation and lung swelling.
