attention and care taken in the management of their systems, processes and raw materials. Their
laboratory, LAS-003, was deemed an accredited laboratory on 2 November 2011 by the local
accreditation body, TTLABS. This certifies that their laboratory fulfils the requirements of the ISO/IEC
17025:2005 Standard for physical testing, namely ASTM C109 and ASTM C191. A significant aspect of
being an accredited laboratory is a thorough and continuous evaluation of the laboratory’s Quality
Management System against the ISO/IEC 17025 Standard for compliance in both Management and
Technical criteria. Therefore, the products offered will meet or exceed local and international
standards.

6.1 Dust Screens

Dust is screened by the use of a piece of equipment called the DustBoss which uses a high-pressure
system to create an ultrafine mist of water which attracts dust particles, resulting in agglomerated
particles falling to the ground or back onto the stockpile.

Potential Health Effects

Inhalation (Acute)
Breathing cement dust may cause nose, throat or lung irritation and choking. The severity of the
effects depends on the degree of exposure.

Inhalation (Chronic)
Prolonged or repeated exposure may cause lung injury including silicosis. The product may contain
crystalline silica, which is classified as a human carcinogen. Long term exposure resulting in silicosis
may also lead to other health problems.

Eye Contact
The cement dust may cause eye irritation, severe burns and damage to the cornea.

Skin Contact
It may also cause dry skin, redness, discomfort, irritation, severe burns, allergic reactions and
thickening of the skin (scleroderma).

Ingestion:
Ingestion of large amounts may cause intestinal distress.

6.2 First Aid measures

Inhalation
Move the individual to fresh air and seek medical attention.
Eye Contact
Thoroughly rinse the eyes with water. Seek medical attention for any abrasions.

Skin Contact
Wash the area with soap and water. Seek medical attention for burns. Use moisturising creams for
irritation.

Ingestion
DO NOT INDUCE VOMITING. Drink plenty water. Seek medical attention.
