HEALTH HAZARD INFORMATION
Acute Health Effects
Swallowed: Ingestion is unlikely under normal conditions of use, however swallowing
of quarry products may result in abdominal discomfort and possibly
increase the risk of gastro-intestinal infections.
Eye: Dust from this product may irritate eyes causing watering and redness.
Skin: Dust from this product may be irritating and abrasive to the skin
Inhaled: Dust may irritate nose, throat and respiratory tract and can exacerbate
pre-existing conditions such as asthma and bronchitis.
Chronic Health Effects
Repeated inhalation of these products may lead to respiratory irritation, inflammation or
sensitisation. Because Quarry Products may contain crystalline silica, repeated inhalation of high
concentrations of respirable dust may cause scarring of the lung (silicosis), lung cancer, and
chronic bronchitis. It is not recommended to repeatedly swallow this material or repeatedly allow
it to come into contact with eyes.
FIRST AID
Swallowed: The patient should be given water to drink and consult a doctor if
abdominal symptoms persist.
Eye: Flush eyes thoroughly with running water for at least ten minutes. If
irritation or redness persist, seek medical attention.
Skin: Wash affected area thoroughly with mild soap and water. Clean
abrasions and cuts and apply a sterile dressing.
Inhaled: Remove patient to fresh air. If respiratory irritation, dizziness or nausea
occurs, seek immediate medical assistance.
FIRST AID FACILITIES
Eye wash station and suitable facilities available to carry out the first aid procedures outlined
above.
ADVICE TO DOCTOR
Treat symptomatically.
PRECAUTIONS FOR USE
Exposure Standards: There is no specific standard for Quarry Products. However
Worksafe Australia Exposure Standard:
Silica-crystalline: 0.2 mg/cubic metre time-weighted average
(TWA). Inspirable dust NOS (not otherwise specified:
10mg/cubic metre time-weighted average (TWA) for dust
containing 1.0% or less of crystalline-silica. (Inspirable dust is
equal to or less than 180 micron size).
Engineering Controls: Any involvement with these products should be conducted in a
way as to avoid contact with the skin and eyes as well as
swallowing and inhalation. Keep exposure to dust as low as
practicable, with the aim of maintaining respirable crystalline
silica dust levels to below 0.05 mg/m3 TWA. Work in open air
and the opening or external openings (such as doors and
windows in buildings) generally provides adequate ventilation.
Special Considerations for Repairs/Maintenance: Avoid breathing dust. Where possible
vacuum or wash down all gear,
equipment or mobile plaint prior to
maintenance and repair work. If
compressed air cleaning cannot be
avoided, were eye and respiratory
protection, and clothing as listed below.
PERSONAL PROTECTION
Skin Protection: Wear loose comfortable clothing and boots and standard duty
leather or equivalent gloves. Long sleeved shirts and long
trousers are recommended if a skin irritation occurs or a person
has a history of skin conditions. All work clothes should be
washed regularly. Clothing according to AS 2161.
Respiratory Protection: When exposed to dust an approved respirator should be worn
that is suitable for respirable particulate and which conforms
with AS/NZS 1715 and AS/NZS 1716. The standards should be
followed in the selection, fit testing, use, storage and
maintenance of the respiratory equipment.
Eye Protection: Dust resistant non-fogging safety goggles or glasses (AS/NZS
1336) should be worn if exposed to dust.
FLAMMABILITY
Quarry products are not flammable, do not support combustion of other materials, and do not cause dust explosions.
SAFE HANDLINE AND STORAGE
Storage and Transport: Avoid breathing dust. Respirable dusts may be generated during
processing, handling, and storage. Use proper control measures, including ventilation, enclosure of materials, covering loads on trucks and wetting down material whilst in use. When stockpiling and handling large quantities of quarry products, care should be taken to avoid having the faces of the stockpile steeper than the natural angle of repose of the material. Steep faces can fall without warning and trap persons resulting in
injury and possible suffocation. When transporting by road, all
loads should be covered.
Spills and Disposal: Spilled material should be wet down with water to reduce dust
generation before cleanup. Clean Quarry materials can be
reused, otherwise dispose of waste quarry materials in
accordance with local authority guidelines.
Fire/Explosion Hazard: Quarry products are non flammable.
OTHER INFORMATION:
Smoking and other dusts: Smoking increases the risk of occupational respiratory diseases.
It is recommended that all storage and work areas should be
smoke-free zones.
