| • HAZARD IDENTIFICATION |
| Chronic Effect: |
Prolonged exposure to crystalline silica dust (<10µm) in significant quantities can lead to silicosis or much more rarely cancer. |
| Inhalation: |
Inhalation of airborne pollutants generated during handling, tipping & loading, pulverization, grinding or crushing may cause silicosis. |
| Ingestion: |
When silica is ingested orally it passes unchanged through the gastrointestinal tract, leaving no trace behind. Small pieces of Silica oxide are equally harmless, as long as they are not large enough to mechanically obstruct the GI tract, or jagged enough to lacerate it's lining. It is indigestible, with zero nutritional value and zero toxicity. |
| Skin: |
Due to the abrasiveness of quartz it may cause irritation to the skin. |
| Eye: |
Airborne particles may cause irritation to eyes. Symptoms may include redness, tearing, stinging and blurred vision. |
| |
|
| • FIRST AID MEASURES |
| Inhalation: |
PPE – 3M FFP2 Type respirators as approved by the Government Mining Engineer. Take all relevant steps to eliminate / minimize the possible source creating airborne pollutants. |
| Skin: |
Wearing of appropriate Personal Protective Equipment – gloves. |
| Ingestion: |
Where applicable wash mouth out with water. |
| Eye: |
Wearing of appropriate personal protective equipment – safety goggles. If contact with the eye(s) occurs, wash with copious amounts of water holding eyelid(s) open. Take care not to rinse contaminated water into the non-affective eye. Seek medical attention. |
| First Aid Facilities: |
Eye wash and normal washroom facilities. |
| Advice to Doctor: |
Treat symptomatically. |
| |
|

|
| • HANDLING & STORAGE |
| Handling: |
Wearing of personal protective equipment to prevent breathing in of airborne pollutants is compulsory. When dealing with this product, repeated or prolonged skin exposure without protection should be prevented in order to lessen the possibility of skin disorders. It is essential that all who come into contact with this material maintain high standards of personal hygiene i.e. Washing hands prior to eating, drinking, smoking or using toilet facilities.
Do not smoke in dusty atmospheres. |
| Storage: |
Where applicable dried silica sand should be stored in a shed preventing the product to become airborne by wind turbulence. |
| |
|
| • EXPOSURE CONTROLS / PERSONAL PROTECTION |
| National Exposure Standards: |
In terms of NOHSA regulation 9.2.(7) the concentration airborne pollutant to which a worker may be repeatedly exposed for normal
8-hour shift (or a 40-hour workweek) constitutes the Time-weighted Average (TWA) limit and is a concentration expressed in milligrams of pollutant per cubic metre of air that may not exceed 0.10mg/m³. |
| Respiratory Protection: |
Where airborne pollutants are generated and exposure standards are exceeded, select and use respirators in accordance with the Mine Health and safety Act – SABS 0338, approved type: 3M FF2 type in accordance with SamQuarz Code of Practise. |
| Eye Protection: |
If possibility of eye contact exists safety glasses with side shields or goggles should be worn as per General Safety Regulations 2 Personal Safety Equipment & Facilities – Occupational Health & safety Act No 85 of 1993. |
| Hand Protection: |
Impervious gloves recommended. Final choice of appropriate gloves will vary according to individuals occupation / tasks. Refer to SamQuarz Code of Practise i.e. Personal Protective Equipment. |
| Body Protection: |
Not normally required. |
| Engineering Controls: |
Ensure sufficient procedures and standards in place to keep airborne concentrations below exposure limits. |
| Biological Limit Values: |
No Biological limit available. |
