Safety First at Smiths Concrete

Health & Safety

When working with concrete, it is always prudent to observe the following safety precautions:

  1. Wear protective clothing, as well as a hard hat, goggles, gloves and Wellington boots
  2. Avoid direct contact between concrete and the skin. Wash off immediately if contact is unavoidable
  3. If eyes come into contact with concrete, rinse with plenty of water and seek medical advice

Concrete and Mortar

1 Identification of Substance
(a) SUBSTANCES
Concrete
Mortar

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

Mortar is a mixture of natural aggregates, cementitious material including cement and water together with admixtures and colourings.The resultant mixture is abrasive and alkaline.

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

(b) Concrete and Mortar 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 and MORTAR
(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 and MORTAR 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 and Mortar
Avoid skin and eye contact.
Concrete and Mortar 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.

HEALTH EFFECTS
Wet Concrete and Mortar
Eyes:
May cause irritation and in severe cases alkali burns.
Skin: Short term contact may cause alkali burns. Prolonged contact may cause both irritant and contact dermatitis.

Concrete and Mortar Dust
On Eyes:
May cause transient irritation.
On Skin: Unlikely to cause harm on brief or occasional contact.
By Inhalation: Inhalation of large quantities of respirable silica may lead to progressive lung damage. This may cause permanent disability and, in extreme cases, may be fatal.
By Ingestion: Unlikely to cause harm. Chronic: Exposure to high levels of silica may cause progressive silicosis.
Others: None known.

Natural Aggregates

1. Identification of Substance
(a) SUBSTANCE
Natural aggregates. Typically:- Crushed rock including granite, dolerite, limestone and basalt. All types of sand, washed/unwashed. Stone/crushed stone. Marine dredged and land won gravels.
(b) SMITHS CONCRETE LIMITED
Southam Road, Banbury,
Oxfordshire, OX16 2RR.
Tel: 01295 278177 Fox: 01295 271402

2. Composition
Natural aggregates are produced from naturally occurring rock
or sand and gravel deposits and consist of combinations of
various minerals including silica.

3. Hazards Identification
Respirable dust inhaled over a prolonged period can be hazardous to health. When the respirable dust contains silica, the risks are increased. Advice on the silica content of the dust produced from individual aggregates is available via the supplying unit on request.

4. First Aid Measures
(a) Inhalation
Remove from exposure to fresh air.
(b) Skin Contact
Wash with water.
(c) Eye Contact
Immediately irrigate with copious amounts of water and seek medical attention.
(d) Ingestion
Remove from exposure to fresh air.

5. Fire Fighting Measures
None needed.

6. Accidental Release Measures
Personal Protection
in the event of a spillage or leakage avoid breathing in the dust. Wear dust mask/respirator and goggles as specified in section 8 - Exposure Controls/Personal Protection.
Environmental Measures
The release of dust into the environment does not constitute a significant hazard. Aggregate should be disposed of in accordance with local authority requirements.
Method of Cleaning
Vaccum system. Water spraying to prevent airborne dust where possible. Avoid dry sweeping which creates dust, damp down surfaces.

7. Handling & Storage
The product should be handled and stored to minimise the creation of airborne dust. Engineering control measures such as containment, enclosed silos, local exhaust ventilation should be applied when airborne dust exposure levels are approached. Bagged aggregates should be palletised and kept dry.
