Page 2 of 6 Revised: 03/01/14 Section 3: HAZARD IDENTIFICATION (continued)

Emergency Overview: Cement is a solid, grey, off white, or white odor less powder. It is not combustible or explosive. A single, short-term exposure to the dry powder presents little or no hazard. Exposure of sufficient duration to wet ceme nt, or to dry cement on moist areas of the body, can cause serious, potentially i rreversible tissue (skin, eye, respiratory tract) damage due to chemical (caustic) burns, including third degree
burns.

Potential Health Effects:

Eye Contact: Airborne dust may cause immediate or delayed irrit ation or inflammation. Eye contact with large amounts of dry powder or with wet cement can cause moderate eye irritation, chemical burns and blindness. Eye expos ures require immediate first aid and medical attention to prevent significant damage to the eye.

Skin Contact: Cement may cause dry skin, discomfort, irritation, severe burns, and dermatitis.

Burns: Exposure of sufficient duration to wet ceme nt, or to dry cement on moist areas of the body, can cause serious, potentially irreversible d amage to skin, eye, respiratory and digestive tracts due to chemical (caustic) burns, i ncluding third degree burns. A skin exposure may be hazardous even if there is no pain or discomfort.

Dermatitis: Cement is capable of causing dermatiti s by irritation and allergy. Skin affected by dermatitis may include symptoms such as, redness, i tching, rash, scaling, and cracking.

Irritant dermatitis is caused by the physical prope rties of cement including alkalinity
and abrasion.

Allergic contact dermatitis is caused by sensitizat ion to hexavalent chromium (chromate) present in cement. The reaction can rang e from a mild rash to severe skin ulcers. Persons already sensitized may react to the first contact with cement. Others may develop allergic dermatitis after years of repe ated contact with cement.

Inhalation (acute): Breathing dust may cause nose, throat or lung ir ritation, including choking, depending on the degree of exposure. Inhalation of high leve ls of dust can cause chemical burns to the nose, throat and lungs.

Inhalation (chronic): Risk of injury depends on duration and level of exposure.

Silicosis: This product contains crystalline silica . Prolonged or repeated inhalation of respirable

crystalline silica from this product can cause sili cosis, a seriously disabling and fatal lung disease. See Note to Physicians in Section 4 f or further information.

Carcinogenicity: Cement is not listed as a carcino gen by IARC or NTP; however, cement contains trace amounts of crystalline silica and hexavalent chromium which are classified by IARC and NTP as known human carcinogens.

Autoimmune Some studies show that exposure to resp irable crystalline silica (without silicosis) or Disease: that the disease silicosis may be associat ed with the increased incidence of several autoimmune disorders such as scleroderma (thickeni ng of the skin), systemic lupus erythematosus, rheumatoid arthritis and diseases a ffecting the kidneys.

Tuberculosis: Silicosis increases the risk of tube rculosis.

Renal Disease: Some studies show an increased inci dence of chronic kidney disease and end-stage renal disease in workers exposed to respirable crys talline silica.MSDS: Lafarge Portland Cement

Page 3 of 6 Revised: 03/01/14 Ingestion: Do not ingest cement. Although ingestion of small quantities of cement is not known to be harmful, large quantities can cause chemical burns in the mouth, throat, stomach, and digestive tract.

Medical Conditions Individuals with lung disease (e.g. bronchitis, e mphysema, COPD, pulmonary Aggravated by Exposure: disease) or sensitivity to hexavalent chromium can be aggravated by exposure.

Section 4: FIRST AID MEASURES

Eye Contact: Rinse eyes thoroughly with water for at least 15 minutes, including under lids, to remove all particles. Seek medical attention for ab rasions and burns.

Skin Contact: Wash with cool water and a pH neutral soap or a mild skin detergent. Seek medical attention for rash, burns, irritation, dermatitis, and prolonged unprotected exposures to wet cement, cement mixtures or liquids from wet cement.

Inhalation: Move person to fresh air. Seek medical attention for discomfort or if coughing or other symptoms do not subside.

Ingestion: Do not induce vomiting. If conscious, have perso n drink plenty of water. Seek medical attention or contact poison control center immediately.

Note to Physician: The three types of silicosis include:

• Simple chronic silicosis – which results from long -term exposure (more than 20 years) to low amounts of respirable crystalline silica. Nodules of chronic inflammation and scarring provoked by the respirabl e crystalline silica form in the lungs and chest lymph nodes. This disease may f eature breathlessness and may resemble chronic obstructive pulmonary dise ase (COPD).

• Accelerated silicosis – occurs after exposure to l arger amounts of respirable crystalline silica over a shorter period of time (5 -15 years). Inflammation, scarring, and symptoms progress faster in accelerat ed silicosis than in simple silicosis.

• Acute silicosis – results from short-term exposure to very large amounts of respirable crystalline silica. The lungs become ver y inflamed and may fill with fluid, causing severe shortness of breath and low b lood oxygen levels.

Progressive massive fibrosis may occur in simple or accelerated silicosis, but is more common in the accelerated form. Progressive massive fibrosis results from severe scarring and leads to the destruction of normal lun g structures.

Section 5: FIREFIGHTING MEASURES

Flashpoint & Method: Non-combustible Firefighting Equipment: Cement poses no firerelated hazard. A SCBA is recommended to limit exposures to combustion products when fighting any fire. General Hazard: Avoid breathing dust. Wet cement is caustic.

Extinguishing Media: Use extinguishing media appropriate for surrounding fire. Combustion Products: None. Section 3: HAZARD IDENTIFICATION (continued)MSDS: Lafarge Portland Cement

Page 4 of 6 Revised: 03/01/14 Section 6: ACCIDENTAL RELEASE MEASURES

General: Place spilled material into a container. Avoid actions that cause the cement to
become airborne. Avoid inhalation of cement and co ntact with skin. Wear appropriate protective equipment as described in Se ction 8. Scrape wet cement and place in container. Allow material to dry or solid ify before disposal. Do not wash cement down sewage and drainage systems or into bod ies of water (e.g. streams).

Waste Disposal Method: Dispose of cement according to Federal, State, Pro vincial and Local regulations.

Section 7: HANDLING AND STORAGE

General: Keep bulk and bagged cement dry until used. Stac k bagged material in a secure manner to prevent falling. Bagged cement is heavy and poses risks such as sprains and strains to the back, arms, shoulders and legs d uring lifting and mixing. Handle with care and use appropriate control measures.

Engulfment hazard. To prevent burial or suffocatio n, do not enter a confined space, such as a silo, bin, bulk truck, or other storage c ontainer or vessel that stores or contains cement. Cement can buildup or adhere to th e walls of a confined space. The cement can release, collapse or fall unexpected ly.

Properly ground all pneumatic conveyance systems. The potential exists for static build-up and static discharge when moving cement po wders through a plastic, nonconductive, or non-grounded pneumatic conveyance sy stem. The static discharge may result in damage to equipment and injury to wor kers.

Usage: Cutting, crushing or grinding hardened cement, conc rete or other crystalline silicabearing materials will release respirable crystalli ne silica. Use all appropriate measures of dust control or suppression, and Person al Protective Equipment (PPE)
described in Section 8 below.

Housekeeping: Avoid actions that cause the cement to become airbo rne during clean-up such as dry sweeping or using compressed air. Use HEPA vacuum o r thoroughly wet with water to clean-up dust. Use PPE described in Section 8 b elow.

Storage Temperature: Unlimited. Storage Pressure: Unlimited.

Clothing: Promptly remove and launder clothing that is dus ty or wet with cement. Thoroughly wash skin after exposure to dust or wet cement.

Section 8: EXPOSURE CONTROLS AND PERSONAL PROTECTIO N

Engineering Controls: Use local exhaust or general dilution ventilation o r other suppression methods to maintain dust levels below exposure limits.

Personal Protective Equipment (PPE):

Respiratory Under ordinary conditions no respira tory protection is required. Wear a NIOSH Protection: approved respirator that is properly f itted and is in good condition when exposed to dust above exposure limits.

Eye Protection: Wear ANSI approved glasses or sa fety goggles when handling dust or wet cement to prevent contact with eyes. Wearing contact lenses w hen using cement, under dusty conditions, is not recommended.MSDS: Lafarge Portland Cement

Page 5 of 6 Revised: 03/01/14 Section 8: EXPOSURE CONTROLS AND PERSONAL PROTECT ION ( continued )
