1. OSHA and ACGIH recommended exposure level is 1 fiber/cc and NIOSH recommended exposure level is 3 fibers/cc. This material is slag wool. Other generic terms that are used or have been used to classify this material include mineral wool, stone wool, man-made mineral fiber (MMMF), and man-made vitreous fiber (MMVF). A more recent generic term that has appeared in the literature to describe these glass-like materials is synthetic vitreous fiber (SVF).
2. Portland cement is made essentially of hydraulic calcium silicates contained in crystalline mass not separable into individual components. Substances known to be present are 3CaO.SiO2, 2CaO.SiO2, 3CaO.Al2O3, 4CaO.Al2O3Fe2O3, CaSO4XH2O. Small amounts of CaO, MgO, K2SO, Na2SO4 may be present.

SECTION III
HAZARD IDENTIFICATION

POTENTIAL HEALTH EFFECTS:
ACUTE: The primary component of this product is mineral wool fiber. During application or when dusty conditions exist, mineral wool fiber and cement dust may cause transitory mechanical irritation and caustic burns to skin, eyes or respiratory tract.
EYES: Direct contact with eye can cause mechanical irritation and chemical burns.
SKIN: This material (in wet state or as dust) is not chemically harmful if it gets on the skin and is immediately washed off. However direct contact of Portland cement dust and mineral wool fibers with skin can cause skin irritation (mechanical), itchiness and caustic burns.
INHALATION: Inhalation of dust can cause nose, throat, lungs and upper respiratory tract irritation. Persons exposed to dust may be forced to leave area because of nuisance conditions such as coughing, sneezing and nasal irritation and chemical burning.
INGESTION: If ingested drink plenty of water and contact a physician.
CHRONIC: Persons with chronic or systemic skin or eye disease should use precautions and wear all personal protective equipment when working with this product.

SECTION IV
FIRST AID MEASURES

EYES: In case of contact, immediately flush thoroughly with copious amounts of water occasionally lifting the lower and upper lids (to remove particulates). Get medical attention immediately. Contact lenses should not be worn working with this product.
SKIN: Skin contact is a chemical hazard with Portland cement. Wet cement can dry the skin and cause caustic burns. Mechanical action of fibers on skin can cause itchiness. Irritation of skin may occur with prolonged and repeated contact. Rinse with cool water, followed by washing with soap and warm water. A commercially available skin cream or lotion may be helpful to treat dry skin areas and apply sterile dressing. Wash hands before eating or using restroom.
INHALATION: If exposed to excessive levels of dust, leave area of dust exposure and remain away until coughing and other symptoms subside. Other measures are usually not necessary, however if conditions warrant, get medical attention.
INGESTION: If ingested drink plenty of water and contact a physician.
TARGET ORGANS: Eyes, skin, lungs and respiratory system.
MEDICAL CONDITIONS WHICH MAY BE AGGRAVATED: Pre-exist-ing upper respiratory and lung disease such as, but not limited to, bronchitis, emphysema and asthma.
PRIMARY ROUTS OF ENTRY: Inhalation, eyes and skin contact.
Note to physician: This product is a mechanical irritant, and is not expected to produce any chronic health effects from acute exposures. Treatment should be directed toward removing the source of irritation with symptomatic treatment as necessary.

SECTION V
FIRE FIGHTING MEASURES

The products are none-combustible and do not pose a fire hazard. However, packing material may burn.
Extinguishing Media: Carbon dioxide (CO2), water, water fog, foam, dry chemical
Special Fire Fighting Procedures: No special procedures are expected to be necessary for this product. Normal fire fighting procedures should be followed to avoid inhalation of smoke and gases.
Unusual Fire and Explosion Hazards: None.
Special Fire Fighting Protective Equipment: Observe normal fire fighting procedures.
Flash Point (Method Used): Not applicable.
Upper and lower flammable limits in air: Not applicable.
Autoignition temperature: Not applicable.
Hazardous Combustion Products: Carbon dioxide, carbon monoxide and traces gases.

SECTION VI
ACCIDENTAL RELEASE MEASURES

CONTAINMENT: Not necessary. Treat as inert material.
CLEAN UP: Pick up large pieces. Use gloves to avoid skin irritation. Vacuum dust, preferably with an industrial vacuum cleaner with high efficiency air filiter. If sweeping is necessary, use dust suppressant such as water. Do not dry sweep dust accumulation or use compressed air for clean up. These procedures will help minimize potential exposures.
DISPOSAL: Dispose in sanitary landfill in accordance with local, state and federal requirements.

SECTION VII
HANDLING AND STORAGE

HANDLING: Use protective equipment to avoid irritation as described in Section 8.
STORRAGE: Warehouse storage should be in accordance with packing directions. Material should be kept dry and protected from the elements.

SECTION VIII
EXPOSURE CONTROL/PERSONAL PROTECTION

ENGINEERING CONTROLS: Provide general ventilation and local exhaust ventilation to meet TLV requirements of individual ingredients (see Section 2) and to control dusting conditions.
If cutting or trimming with power equipment, dust collectors and local ventilation should be used.
Avoid unnecessary exposure to dust and handle with care. Keep work area clean of dust and fibers by using an industrial vacuum cleaner with high efficiency filter or wetting down area with water. Never use compressed air and avoid dry sweeping.
EYE PROTECTION: Wear safety glasses with side shields or goggles to avoid eye irritation.
SKIN: Avoid prolonged contact with wet cement from application or perspiration. Workers should shower immediately with soap and water after prolonged contact. Cement burns with little warning because little heat is sensed.
RESPIRATORY PROTECTION: Wear a NIOSH/MSHA-approved dust respirator in poorly ventilated areas, where local exhaust is not feasible, if TLV is exceeded, and/or when dusty conditions exist.
OTHER CLOTHING: Wear tight fitting goggles and gloves when dusty conditions exist. Wear long-sleeved, loose fitting clothing at the neck and wrists and minimize skin contact. Wash work clothing separately from other clothing. Rinse washer thoroughly after use.

CARCINOGENICITY CLASSIFICATION OF INGREDIENTS:
Material IARC NTP
Man Made Vitreous Fiber Group 3 None
Portland Cement Not Listed Not Listed

In October 2001, the International Agency for Research on Cancer (IARC) classified mineral wool fibers (rock or slag) as Group 3 (not classifiable as to carcinogenicity to humans). IARC noted specifically: “no evidence of increased risks of lung cancer or mesothelioma (cancer of the lining of the body cavities) from occupational exposures during manufacture of these materials, and inadequate evidence overall of any cancer risk.” This was a reversal of the IARC finding in 1987 of a Group 2B designation (possibly carcinogenic to humans) based on earlier studies in which animals were injected with large quantities of slag wool fibers.

Portland cement is not listed as a carcinogen by NTP, OSHA, or IARC. It may, however, contain trace amounts of substances listed as carcinogens by these organizations.

Crystalline silica, a potential trace level contaminant in Portland cement, is now classified by IARC as a known carcinogen (Group 1). NTP has characterized respirable silica as “reasonable anticipated to be (a) carcinogen”.
