2. HEALTH HAZARD INFORMATION


2.1 Health Effects - Acute

Swallowed

Unlikely to cause significant effects.

Eye

Physical nature of powder may cause mechanical irritation.

Skin

Unlikely to cause irritant effects.

Inhaled

Acute exposure to dust may cause irritation to respiratory tract.

2.2 Health Effects - Chronic

Fluorspar may contain up to 1.5% silica (amorphous or crystalline) as an impurity. Chronic inhalation exposure to crystalline silica may result in serious adverse health effects particularly if the silica is of respirable size (approximately < 7 micron aerodynamic diameter). Crystalline silica has been shown to induce lung cancer in laboratory animals and there is limited evidence that it may cause lung cancer in humans. The International Agency for Research on Cancer (IARC) has classified crystalline silica as a probable human carcinogen (2A).

2.3 First Aid

Swallowed

If swallowed, give a glass of water. If feeling unwell contact a doctor or .

Eye

If in eyes wash with water for at least 15 minutes. If irritation persists see a doctor.

Skin

Wash affected areas thoroughly with water.

Inhaled

If discomfort or irritation occurs remove to fresh air.

First Aid Facilities

Ensure an eye bath and safety shower are available and ready for use.

2.5 Advice to Doctor

Treat symptomatically based on judgement of doctor and individual reactions of patient.

2.6 Toxicity Data

Oral LD50 = 4250 mg/kg (Rat) Dermal LD50 = not available Inhalation LC50 = not available


3. PRECAUTIONS FOR USE


3.1 Exposure Standards

The following exposure limits have been established by Worksafe : Inorganic fluorides (as F) TWA : 2.5 mg/m3 Crystalline silica TWA : 0.1 or 0.2 mg/m3

3.2 Engineering Controls

The generation of dusts should be avoided. Where possible, dampen material. If dust generation is unavoidable, local exhaust ventilation should be used to achieve concentrations below TWA.

3.3 Personal Protection

A Class P1 particulate filter respirator should be used where dusts may be formed, in accordance with n and New Zealand Standard AS/NZS 1716:1994. Eye goggles should be worn as a general precaution if dust is likely to be formed. Wash hands and face thoroughly after handling and before work breaks, eating, drinking, smoking and using toilet facilities.

3.4 Flammability

Not flammable.
