2. INGREDIENTS: COMPOSITION/INFORMATION
The value is for inhalable(total) particulate matter containing no asbestos and <1% crystalline silica OSHA Regulatory Status: This material is classified hazardous under OSHA regulations.
3. HAZARDS INDENTIFICATION
EMERGENCY OVERVIEW
Non-combustible black solid or powder. Abrasive particulate may cause minor eye and
skin irritation. Inhalation of high concentrations may cause transient upper respiratory
irritation.
POTENTIAL HEALTH EFFECTS
EYE: Particulate matter may scratch the cornea or cause other mechanical injury to the eye
SKIN: May cause minor irritation. Not absorbed through the skin
INGESTION: Relatively non-toxic.Ingestion is not anticipated under normal working conditions.
INHALATION: Product will act as a nuisance dust. Inhalation of high concentrations of dust may cause coughing and mild, transitory respiratory irritation.
SIGNS AND SYMPTOMS: Scratching or physical damage to the eyes can cause irritation, redness, pain, tear formation, blurred vision, and light sensitivity.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Repeated inhalation of dusts over time may aggravate pre-existing respiratory disease.
4. FIRST AND MEASURES
EYE: Flush eyes with lukewarm water for 15 minutes opening and closing eyelids to ensure adequate rinsing. If redness,irritation, pain, or tearing occurs,seek medical attention.
SKIN: Wash area with soap and water. Wash contaminated clothing. Seek medical attention if symptoms occur.
INHALATION: Not expected. If inhalation of high concentrations occurs, remove to fresh air. Acertified professional should administer oxygen or CPR if indicated.Seed immediate medical attention.
INGESTION: None required for small amounts. If large amounts are ingested, seek medical attention.
5. FIRE FIGHTING MEASURES
FLAMMABLE PROPERTIES
FLASH POINT: Not Applicable
FLAMMABLE LIMITS: LEL: Not Applicable UEL: Not Applicable
NFPA CLASSIFICATION:
HEALTH: 0 FLAMMABILITY: 0 INSTABILITY: 0
EXTINGUISHING MEDIA: Any. Use media apppropriate for surrounding fire.
FIRE AND EXPLOSION HAZARDS: Non-flammable,non-combustible.Product will not burn.
HAZARDOUS DECOMPOSITION PRODUCTS: None.
FIRE FIGHTING INSTRUCTIONS: Firefighters should wear a NIOSH approved full-facepiece self-contained breathing apparatus(SCBA) operated in positive pressure mode and full turnout or bunker gear.
6. ACCIDENTAL RELEASE MEASURES
Isolate hazard area and deny entry to unauthorized and /or unprotected personnel .
Vacuum small amounts. Gently shovel or scoop large amounts into clean dry container for later recycle or disposal. Water mist may be added as necessary to control the level of airborne dusts. Wear appropriate protective equipment( See Section 8)
7. HANDLING AND STORAGE
Store in dry area in closed containers. Storage and work areas should be periodically cleaned to minimize dust accumulation. Avoid dust inhalation and promulgation. DO NOT use compressed air or dry sweeping to remove dust from work area. Dusts should be removed using an appropriately equipped vacuum. If a vacuum is unavailable. Only wet-clean-up methods should be used(I.e.wet sweeping,misting,etc), Moisture should be added as necessary to reduce exposure to airborne respirable dust.
Under dusty conditions, employees should wear coveralls or other suitable work clothing Vacuum grossly contaminated clothing before removal, Practice good housekeeping. Wash thoroughly after handling. Change contaminated clothing. Do not reuse until laundered.
8. EXPOSURE CONTROLS/PERSONAL PROTECTION
RESPIRATORY: Under normal working conditions,below acceptable exposure guidelines.none is required. For concentrations to 10* above the PEL, a NIOSH/MSHA aproved dust mist respirator should be worn. Appropriate respirator selection will be dependent upon the magnitude of exposure and must be selected in accordance with 29 CFR 1910.134.
SKIN: Protective gloves, as necessary to prevent irritation.
EYES: Safety-glasses with side shields or goggles to prevent dust and particles from entering the eye.
ENGINEERING CONTROLS: General ventilation. Local exhaust may be necessary for processes which generate large quantities of airborne dust.
OTHER: None
9. PHYSICAL AND CHEMICAL PROPERTIES
10. STABILITY AND REACTIVITY
STABILITY: Stable under normal ambient conditions of temperature and pressure.
REACTIVITY/INCOMPATIBILITY: None known.
DECOMPOSITION PRODUCTS: Not Applicable.
HAZARDOUS POLYMERIZATION: Will not occur.
11. TOXICOLOGICAL INFORMATION
EYE: Particulate matter may cause physical injury to the eye
SKIN: May cause minor skin irritation
INHALATION: May cause minor transient respiratory irritation
INGESTION: None known.
CHRONIC: Physiologic consequence of particulate overload of the respiratory tract involves altered macrophage function, sequestration of particles and increased lung burden.When large numbers of particles reach the interstitium, interstitial macrophage-fibroblast interactions are stimulated which in turn can stimulate fibrosis. Once overloaded, the macrophages can also become sequestrian compartments. As dust concentrations with in the lung increase, the retention half-life for particulate matter also increases.
SUBCHRONIC: No Data
OTHER: None known
12. ECOLOGICAL INFORMATION
Black silicon carbide does not contain ozone depleting substances. It is not expected to exert an ecotoxic effect or bioconcentrate in the food chain.
13. DISPOSAL CONSIDERATIONS
Dispose of according to applicable federal, state, and local regulations. Dispose per 40 CFR 261 and 262.
