General Product Information   Trace Elements: Ready-mixed concrete is made from materials mined from the earth. Trace amounts of naturally occurring elements might be detected during chemical analysis of these materials.
Inhalation Remove to fresh air. Seek medical help if coughing and other symptoms do not subside. (Inhalation of gross amounts of the dry ingredients in Ready-mixed concrete requires immediate medical attention.)
Skin contact Wash skin with cool water and pH ‐ neutral soap or a mild detergent intended for use on skin. Seek medical treatment if irritation is caused by prolonged exposure to wet concrete, liquids from wet concrete products, or prolonged wet skin exposure to the dry ingredients in Ready ‐ Mix concrete.
Eye contact Immediately flush eyes thoroughly with water. Continue flushing eye for at least 15 minutes, including under eye lids, to remove all particles. Call physician if irritation persists.
Ingestion Do not induce vomiting. If conscious, have the victim drink plenty of water and call a physician immediately.
Suitable extinguishing media Non‐flammable. Use appropriate extinguishing media for surrounding fire.
Unsuitable extinguishing media None known
General Fire Hazards See Section 9 for Flammability Properties. Non ‐ combustible.
Hazardous Combustion Products None
Firefighting equipment/instructions No Specific precautions.
Recovery and Neutralization Stop the flow of material, if this is without risk.
Materials and methods for containment and clean-up Collect dry material using a scoop. Avoid actions that cause dust to become airborne. Avoid inhalation of dust and contact with skin. Scrape up wet material and place in an appropriate container. Allow the material to harden before disposal.
Emergency Measures Keep unnecessary personnel away.
Personal precautions and emergency procedures Wear appropriate protective equipment and clothing during clean‐up of materials that contain or may liberate Limestone dust.
Prevention of Secondary Hazards None
Environmental Precautions Avoid discharge of fine particulate matter into drains or water courses.
Handling Procedures Avoid contact with eyes and skin. Promptly remove clothing which is wet with concrete and launder before reuse. Wash thoroughly after exposure to wet concrete mixtures.
Incompatibilities Wet ready-mixed concrete is alkaline. As such it is incompatible with acids, ammonium salts and aluminum metal.
Engineering Measures Use local exhaust or general dilution ventilation to control exposure within applicable limits.
Personal Protective Equipment: Respiratory Use local or general ventilation to control exposures below applicable exposure limits. NIOSH or MSHA approved particulate filter respirators should be used in the context of respiratory protection program meeting the requirements of the OSHA respiratory protection standard [29 CFR 1910.134] to control exposures when ventilation or other controls are inadequate or discomfort or irritation is experienced. Use appropriate respirator/filter cartridge selection.
Personal Protective Equipment: Hands Where prolonged exposure to unhardened concrete products might occur, wear impervious gloves to eliminate skin contact. Periodically wash areas contacted by wet cement or its dry ingredients with a pH neutral soap and water. Wash again at the end of the work. If irritation persists, immediately wash the affected area and seek treatment.
Personal Protective Equipment: Eyes When engaged in activities where wet concrete or its dry ingredients could contact the eye, wear safety glasses with side shields or goggles.
Personal Protective Equipment: Skin and Body Where prolonged exposure to unhardened concrete products might occur, wear impervious clothing to eliminate skin contact. Where required, wear boots that are impervious to water to eliminate foot and ankle exposure. If clothing becomes saturated with wet concrete, it should be removed and replaced with clean dry clothing.

Incompatible Products Wet Ready‐Mix concrete is alkaline. As such it is incompatible with acids, ammonium salts and aluminum metal.
Hazardous Decomposition Products Will not spontaneously occur.
Acute Toxicity Wet concrete is not known to be toxic. Toxicity related to major components of concrete: cement, fly ash, and silica sand are negated in wet concrete form. The matrix precludes the inhalation of these constituents which could normally be of an occupational safety concern. The admixture and air entraining agents are sulfonate solutions which are not considered toxic.
Potential Health Effects: Skin Corrosion Property /Stimulativeness Discomfort or pain cannot be relied upon to alert a person to a hazardous skin exposure. Consequently, the only effective means of avoiding skin injury or illness involves minimizing skin contact, particularly contact with wet concrete. Exposed persons may not feel discomfort until hours after the exposure has ended and significant injury has occurred. Exposure during the handling or mixing of the dry ingredients in Ready‐Mix concrete may cause drying of the skin with consequent mild irritation or more significant effects attributable to aggravation of other conditions. Exposure to wet concrete may cause more severe skin effects including thickening, cracking or fissuring of the skin. Prolonged exposure can cause severe skin damage in the form of (caustic) chemical burns.
Potential Health Effects: Eye Critical Damage/ Stimulativeness Exposure to airborne dust during the sawing of hardened concrete or handling/mixing of the dry ingredients in Ready‐Mix concrete may cause immediate or delayed irritation or inflammation. Eye contact by splashes of wet concrete may cause effects ranging from moderate eye irritation to chemical burns. Such exposures require immediate first aid (see Section 4) and medical attention to prevent significant damage to the eye.
Potential Health Effects: Ingestion Although inadvertent ingestion of small quantities of wet concrete or its dry ingredients are not known to be harmful, accidental ingestion of larger quantities can be harmful and requires immediate medical attention.
Potential Health Effects: Inhalation The ingredients in Ready‐Mix concrete contain crystalline silica. Exposure to these ingredients in excess of the applicable TLV or PEL may cause or aggravate other lung conditions. Exposure to the dry ingredients in Ready‐Mix concrete may cause irritation to the moist mucous membranes of the nose, throat, and upper respiratory system.


A: General Product Information May cause cancer. Crystalline Silica: Exposures to respirable crystalline silica are not expected during the normal use of this product. Prolonged and repeated exposure to airborne free respirable crystalline silica can result in lung disease and/or lung cancer. IARC states that crystalline silica in the form of quartz or cristobalite from occupational sources is carcinogenic to humans (Group 1).
