Section 3: Hazards Identification
Acute Health Effects Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of breath.
Chronic Health Effects Chronic exposure may cause asbestosis, interstitial fibrosis of the lung tissue, which may develop within 4 years to 9 years, but onset may be typically delayed 20 years to 40 years after first exposure. Death from asbestosis may be due to respiratory or cardiac failure. Secondary lung infections may also occur. Chronic exposure of asbestos to workers may also cause pleural effusion as early as 3 years to 4 years after initial exposure. Chronic exposure of asbestos to workers also increases the chance of pleural and peritoneal mesotheliomas, bronchogenic carcinoma, lung cancer, and cancers of the gastrointestinal tract and larynx. The latent period for mesothelioma is 3 years to 40 years; for lung cancer, 15 years to 30 years.
Aggravation of
Pre-existing Conditions
Persons with respiratory function may be more susceptible to the effects of this substance.
Acute Health Effects May cause gastrointestinal irritation.
Chronic Health Effects Exposure to asbestos fibers may be involved in cancers of the buccal cavity and pharynx, esophagus, stomach, colon, and rectum.
Aggravation of
Pre-existing Conditions
Medical conditions that may be aggravated by exposure: None anticipated.
Eye Contact
Acute Health Effects Contact with eye may cause irritation.
Chronic Health Effects Prolonged or repeated contact may cause severe irritation.
Aggravation of
Pre-existing Conditions
Medical conditions that may be aggravated by exposure: None anticipated.
Skin Contact
Acute Health Effects May cause irritation, depending on duration of contact.
Chronic Health Effects Asbestos fibers may penetrate the skin and result in "asbestos corns," due to thickening of the skin around the implanted fiber. These corns usually occur on the hands and forearms, and they disappear on removal of the fibers.
Aggravation of
Pre-existing Conditions
Persons with pre-existing skin problems may be more susceptible to the effects of this substance.
  Health effects described above are based on published scientific information available for review and evaluated on behalf of this product. Actual signs and symptoms experienced may vary due to conditions at the time of exposure.
Section 4: First Aid Measures
After Inhalation Remove to fresh air. If conscious, have victim clear nasal passages. Restore breathing (e.g., artificial respiration, CPR). Seek medical attention, as necessary, if symptoms develop or persist.
After Skin Contact In case of contact, wipe off excess material from skin then immediately flush skin with plenty of water for at least 15 minutes. Wash clothing before reuse. Call a physician, if irritation occurs.
After Eye Contact Holding eyelids open, do not allow victim to rub their eyes. Gently flush eyes for 15 minutes with large quantities of water. Seek medical attention if irritation develops or persists.
After Ingestion Never give anything by mouth to an unconscious person. Do NOT induce vomiting. Get medical attention if symptoms appear.

Section 6: Accidental Release Measures
Spill Procedures Protect against identified hazards through use of prescribed personal protection equipment, proper work and hygiene practices. Limit foot and vehicular traffic to minimize mechanical agitation and dispersion. Employ a vacuum, equipped with HEPA (High Efficiency Particulate Air) filter, for clean-up of the spill material. If no vacuum is available, use a broom and shovel to collect excess powder in the area. Residual material should then be cleared, utilizing the process of wet sweeping, to avoid dust generation.
Containment Techniques This is a solid material and will not travel far from the spill location unless mechanically agitated. Therefore, no specific containment techniques are recommended outside of restricting access to the spill location. During spill cleanup, residual wash waters should be contained and collected for proper disposal.
Spill Response Equipment The following equipment is recommended for spill response:
• vacuum, equipped with a HEPA filter
• broom, wet mop
• dustpan, shovel, or scoop
• bags, drums, or sacks for collection

Note: Non-sparking equipment may be selected, based on location specific requirements and individual work site evaluations.
Personal Protective Equipment Employees should utilize the following protective equipment when performing spill response activities:
• gloves (rubber or leather)
• cotton or Tyvek coveralls
• chemical/safety impact goggles
• respiratory equipment recommended in Section 8
Section 7: Handling and Storage
Handling When handling this product, all personnel are directed to:
• Wear all specified elements of PPE, as directed by this document, or under location specific requirements, whichever is more conservative.
• Avoid creating dust, where possible.
Storage The following information provides the appropriate and recommended methods for safe storage and maintenance of product integrity:
• Store in a cool, dry, well-ventilated area.
• Product containers (paper bags, nylon bags, drums, etc.) are prone to physical damage. Care should be taken in storage and handling in order to prevent damage.
• Avoid contact with oxidizers and chemically active metals, since violent reactions may occur.
Section 8: Exposure Controls / Personal Protection
Engineering Controls If user operations generate dusts, use process enclosures, local exhaust ventilation, or other engineering controls to keep airborne levels below recommended exposure limits.
Respiratory Protection If the exposure limit is exceeded and engineering controls are not feasible, a full facepiece particulate respirator (NIOSH type N100 filters) may be worn for up to 50 times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids. glycerine, etc.) are present, use a NIOSH type R or P filter. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye/Face Protection Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
Work Hygiene Practices To control potential exposures, avoid creating dust. Always wear appropriate protective equipment when handling. To avoid skin contact, gloves (leather or rubber) should be worn when handling containers of this substance. Do not eat, drink, smoke or apply cosmetics while using/handling. Always wash hands and face after handling.
• Avoid direct skin contact when possible.
• Do not eat, drink, smoke, or perform other hand-to-mouth activities in product use or handling area.
• Wash thoroughly after handling this product.
