2. Composition
Concrete is a mixture of natural aggregates, lightweight aggregates which may include Lytag, Blast Furnace Slag and cementitious material including cement, pulverised fuel ash (PFA) and water. Admixtures may be added.

3. Hazards Identification
(a) Wet Concrete
Contact with wet concrete can cause:
1) Irritant Contact Dermatitis
2) Allergic Contact Dermatitis
3) Cement Burn

(b) Concrete Dust
Cutting and surface treatment of hardened concrete can create dust and flying fragments. The dust created could contain particles of a respirable size which may contain silica.
When the respirable dust contains silica, the risks are increased. Extended periods of exposure to high concentrations of such dust can be hazardous to health.

4. First Aid Measures
WET CONCRETE.
(a) Skin Contact
Immediately wash with copious amounts of water. Remove contaminated clothing. Seek medical attention.
(b) Eye Contact
Immediately irrigate with copious amounts of water. Seek medical attention.
(c) Ingestion
Remove from exposure to fresh air. Seek medical attention.

CONCRETE DUST.
(a) Inhalation Remove from exposure to fresh air.
(b) Skin Contact
Wash with water.
(c) Eye Contact
Immediately irrigate with copious amounts of water. Seek medical attention.
(d) Ingestion
Remove from exposure to fresh air.

5. Fire Fighting Measures
None needed.

6. Accidental Release Measures
Personal Protection
Avoid skin and eye contact. Wear protective equipment as specified in section 8 – Exposure Controls/Personal Protection.
Environmental Measures
Prevent entry into drains and water courses
Method of cleaning
To avoid hardening, recover as quickly as possible in the wet or semi dry state using suction system or mechanical loading shovel. Water spray to avoid the creation of airborne dust. Avoid skin contact

7. Handling & Storage
Wet Concrete.
Avoid skin and eye contact.
Concrete Dust.
Cutting and surface treatment of hardened concrete should be worked to minimise the creation of airborne dust.
Engineering control measures such as containment and local exhaust ventilation should be applied when airborne dust exposure levels are approached.

8. Exposure Controls/ Personal Protection
