Trace Elements
As masonry cement is made from materials mined from the earth and is processed using energy provided by
fuels, trace amounts of naturally occurring, potentially harmful chemicals might show up during chemical
analysis. For example, these products may contain up to 50% of insoluble residue, some of which may be up to
15% crystalline silica. Other trace components may include potassium and sodium sulphate compounds,
chromium compounds and nickel compounds.
SECTION 3 - HAZARDS IDENTIFICATION
Emergency Overview
Masonry cement is a light grey powder that poses little immediate hazard. A single short-term exposure to the
dry powder is not likely to cause serious harm. However, exposure of sufficient duration to wet masonry cement
can cause serious, potentially irreversible tissue (skin or eye) destruction in the form of chemical (caustic) burns,
including third degree burns. The same type of tissue destruction can occur if wet or moist areas of the body are
exposed for sufficient duration to dry masonry cement.
Potential Health Effects
Relevant routes of exposure: eye contact, skin contact, inhalation, and ingestion.
Effects Resulting from Eye Contact:
Exposure to airborne dust may cause immediate or delayed irritation or inflammation. Eye contact by larger
amounts of dry powder or splashes of wet masonry cement may cause effects ranging from moderate eye irritation
to chemical burns and blindness. Such exposures require immediate first aid (see Section 4) and medical attention
to prevent significant damage to the eye.

Masonry Cement Material Safety Data Sheet
Effects Resulting from Skin Contact:
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
cement. Exposed persons may not feel discomfort until hours after the exposure have ended and significant injury
has occurred.
Exposure to dry masonry cement may cause drying of the skin with consequent mild irritation or more
significant effects attributable to aggravation of other conditions. Dry masonry cement contacting wet skin or
exposure to moist or wet masonry cement 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. Some individuals
may exhibit an allergic response upon exposure to masonry cement, possibly due to trace amounts of chromium.
The response may appear in a variety of forms ranging from mild rash to severe skin ulcers. Persons already
sensitized may react to their first contact with the product. Other persons may first experience this effect after
years of contact with masonry cement products.
Effects Resulting from Inhalation:
Masonry cement may contain trace amounts of free crystalline silica. Prolonged exposure to respirable free
crystalline silica may aggravate other lung conditions. It also may cause delayed lung injury including silicosis, a
disabling and potentially fatal lung disease, and/or other diseases. Also see Carcinogenic Potential below.
Exposure to masonry cement may cause irritation to the moist membranes of the nose, throat, and upper
respiratory system. It may also leave unpleasant deposits in the nose.
Effects Resulting from Ingestion:
Although small quantities of dust are not known to be harmful, ill effects are possible if larger quantities are
consumed. Masonry cement should not be eaten.
Carcinogenic Potential:
International Agency for Research on Cancer (IARC), The National Toxicology Program (NTP), or
Occupational Safety and Health Administration (OSHA) do not list masonry cement as a carcinogen.
IRAC has designated crystalline silica, a potential trace contaminant in masonry cement, to be carcinogenic to
humans (Group 1). The NTP indicates that crystalline silica is reasonably anticipated to be a carcinogen (Group
2).
Medical conditions which may be aggravated by inhalation or dermal exposure:
- Pre-existing upper respiratory and lung diseases.
- Unusual (hyper) sensitivity to hexavalent chromium (chromium +6) salts.
SECTION 4 - FIRST AID
Eyes:
Immediately flush eyes thoroughly with water. Continue flushing eyes for at least 15 minutes, including under
lids, to remove all particles. Call physician immediately.
Skin:
Wash skin with cool water and pH-neutral soap or a mild detergent intended for use on skin. Seek medical
treatment in all cases of prolonged exposure to wet cement, cement mixtures, liquids from fresh cement products,
or prolonged wet skin exposure to dry cement.
Inhalation of Airborne Dust:
Remove to fresh air. Seek medical help if coughing and other symptoms do not subside. Inhalation of gross
amounts of masonry cement requires immediate medical attention.

SECTION 6 - ACCIDENTAL RELEASE MEASURES
Collect dry material using a scoop. Avoid actions that cause dust to become airborne. Avoid inhalation of dust
and contact with skin. Wear appropriate personal protective equipment as described in Section 8.
Scrape up wet material and place in an appropriate container. Allow the material to dry before disposal. Do not
attempt to wash masonry cement down drains.
Dispose of waste material according to local, state and federal regulations.
SECTION 7 - HANDLING AND STORAGE
Keep masonry cement dry until used. Normal temperatures and pressures do not affect the material. Promptly
remove dusty clothing or that which is wet with cement fluids and launder before reuse. Wash thoroughly after
exposure to dust or wet cement mixtures.
SECTION 8 - EXPOSURE CONTROLS/PERSONAL PROTECTION
Skin Protection:
Prevention is essential to avoiding potentially severe skin injury. Avoid contact with unhardened (wet) masonry
cement products. If contact occurs, promptly wash affected area with soap and water. Where prolonged exposure
to unhardened masonry cement products might occur, wear impervious clothing and gloves to eliminate skin
contact. Where required, wear boots that are impervious to water to eliminate foot and ankle exposure.
Do not rely on barrier creams; barrier creams should not be used in place of gloves.
Periodically wash areas contacted by dry masonry cement or by wet cement or concrete fluids with a pH neutral
soap. Wash again at the end of the work. If irritation occurs, immediately wash the affected area and seek
treatment. If clothing becomes saturated with wet mortar , it should be removed and replaced with clean dry
clothing.
Respiratory Protection:
Avoid actions that cause dust to become airborne. Use local or general ventilation to control exposures below
applicable exposure limits.
Use NIOSH/MSHA-approved (under 42 CFR 84) respirators in poorly ventilated areas, if an applicable
exposure limit is exceeded, or when dust causes discomfort or irritation. Advisory: Respirators and filters
purchased after July 10, 1998 must be certified under 42 CFR 84.
Ventilation:
Use local exhaust or general dilution ventilation to control exposure within applicable limits.

Date of previous MSDS: October 2004
Masonry cement should only be used by knowledgeable persons. A key to using the product safely requires the
user to recognize that masonry cement chemically reacts with water, and that some of the intermediate products of
this reaction (that is, those present while a masonry cement product is setting) pose a far more severe hazard than
does masonry cement itself.
While the information provided in this material safety data sheet is believed to provide a useful summary of the
hazards of masonry cement as it is commonly used, this sheet cannot anticipate and provide all of the information
that might be needed in every situation. Inexperienced product users should obtain proper training before using
this product.
In particular, the data furnished in this sheet do not address hazards that may be posed by other materials mixed
with masonry cement to produce masonry cement mortar. Users should review other relevant material safety data
sheets before working with this masonry cement or working on masonry cement products, for example, masonry
assemblies.
