Signs and Symptoms of Overexposure During Grinding; 
Route of Entry        Acute Effect            Chronic Effect

Eyes            Dusts may irritate eyes            None expected

Inhalation:    Dusts may cause irritation       Continued excessive exposure
                  to nose, throat or lungs         to abrasive grains may affect
                  resulting in coughing or         breathing capacity. Signs of
                  shortness of breath.               excessive exposure might
                                                         include deposit of material in
                                                         the eyes, ears, nasal passages
                                                         and irritation of the mucous
                                                         membranes. 

Ingestion; Non-toxic, but ingestion           None Expected
                 should be avoided.     

Skin; Dust may irritate some                 None Expected
            individuals. 

Medical Conditions Generally Recognized as Being Aggravated by Exposure;
May aggravate existing respiratory problems. 

Dust generated from the intended use of this product may contain trace amounts 
of inorganic fluorides. Excessive exposure to fluoride has been shown in NIOSH 
studies to increase  bone density. Dust generated from the intended use of this 
product may contain trace levels of phonetic resins which may under excessive 
exposure cause skin sensitization and airway obstruction.

Emergency First Aid Procedures;
Route of Entry        First Aid Procedure
Eyes;    Irritant. Treat as a foreign body in the eye. Flush with large 
            amounts of clean water for at least 15 minutes.
            If irritation persist, obtain medical assistance. 

Inhalation;    Classified as a nuisance dust. Remove to fresh air.
            Provide artificial respiration as needed and obtain
            medical assistance. 

Ingestion; Obtain medial assistance. Contact poison control center. 

Skin;    Wash affected areas with soap and water. Obtain medical
            assistance if aggravated skin conditions persist. 

Fire and Explosion Hazard Data;

    Flash Point;    Not applicable. 
    Flammable Limits;    LEL: Not Applicable    UEL; Not Applicable
  Extinguishing Media;     Water, foam or CO2
  Special Fire Fighting Procedures;     Toxic fumes are evolved on burning. 
  Unusual Fire & Explosion Hazards;   Fumes from burning cured     
    Phenol/Formaldehyde
        resin may contain trace amounts of formaldehyde
        which can cause eye, nose and throat irritation. 
        The short term exposure limit for formaldehyde is
        2ppm. Breathing apparatus should be worn to fight
        serious fires in confines spaces.

believed to be accurate as of the date hereof; however, no warranty is made with 
respect to the accuracy of the information or the suitability of the 
recommendations, and no liability is assumed to any user thereof. 

Reactivity Date;
    Stability; Stable
Hazardous Polymerization; Will not occur
Decomposition Products; During use, dust and decomposing organic fumes are 
generated which may contain trace amounts of phenol, formaldehyde and fluorides. 
In most cases, the material removed from the work piece will be significantly 
greater than the grinding wheel components. Coolants or other surface residues 
may produce other decomposition products. 
Conditions to be Avoided; No applicable information found. 

Control Measures; Ventilation; good local exhaust ventilation is essential for 
dry grinding    operations as per ANSI Z88.2, OHSA 29 CFR; 1910.94 
(Ventilation).
Respiratory Protection; Use an approved respirator when airborne contaminant 
levels exceed TLVs and PELs as per OSHA 29 CFR 1910.134 or 139 (Respiratory), 
and OSHA 29 CFR 1910.1000 ( Air Contaminants).
Eye Protection; Wear eye protection as per ANSI Z87.1 and OSHA 29 CFR 1910.33.
Hand Protection; Use Gloves as required. (Arm sleeves or barrier creams may be 
useful in the prevention of dermatitis).
Other Protection; Exercise good personal hygiene. Hearing protection may be 
required as per OSHA 29 CFR 1910.95. (Hearing Protection) during normal use. 

Precautions for Safe Handling and Use;
Spills or Leaks; Collect and pick up materials following normal precautions for 
inert nuisance dusts. 
Disposal; Standard Landfill methods consistent with applicable federal, state 
and local laws. 
Storage; Store in a cool, dry place and as per ANSI B7.1.
Normal Usage; Observe recommended operating speeds. Provide adequate ventilation 
for nuisance dust. Also, see ANSI B7.1.
