PRODUCT SAFETY
SECTION 1. IDENTIFICATION OF THE PRODUCT AND SUPPLIER
Product Name : Carbon Black Includes all grades as manufactured by Carbon simorgh co.
Recommended Use : Reinforcing filler in rubber products, pigment in polymers and printing inks.
Supplier Name : CARBON SIMORGH CO.
SECTION 2. HAZARDS IDENTIFICATION
Eye:
Carbon black may produce eye irritation.
Skin Contact:
The product is not skin irritant.
Infiltration Trough skin:
Infiltration is not probable, carbon black being a dry solid material.
Ingestion:
Specific effect is not known.
Inhalation:
At high concentrations of carbon black dust (above TLV) inhalation may produce irritation of lungs.
SECTION 3. COMPOSITION / INGREDIENTS INFORMATION
Carbon Black, amorphous (99% by weight))
Chemical formula: C
CAS number: 1333-86-4
SECTION 4. FIRST AID MEASURES
Inhalation :
Take affected persons into fresh air, if necessary. Remove from exposure. Short-term exposures to elevated concentrations may produce temporary discomfort to the upper respiratory tract, which may result in coughing and wheezing.
Eye :
Carbon black is not a chemical irritant. Treat symptomatically for mechanical irritation. Rinse eyes thoroughly with large volumes of water keeping eyelid open to remove dust. If irritation persists or symptoms develop, seek medical attention.
Skin :
Wash hands and other exposed skin with mild soap and water (repeat washing may be necessary to remove carbon black). If symptoms develop, seek medical attention.
Ingestion :
No adverse effects are expected from carbon black ingestion. Do not induce vomiting. If conscious, rinse mouth with water. Never give anything by mouth to an unconscious person.
SECTION 5. FIRE FIGHTING MEASURES
Extinguishing Media :
Use foam, carbon dioxide (CO2), dry chemical powder or water fog.
DO NOT USE high pressure water stream as this may spread burning powder (burning powder will float).
Hazards from Combustion Products:
Products of combustion include carbon monoxide (CO), carbon dioxide (CO2) and oxides of sulphur.
It may not be obvious that carbon black is burning unless the material is stirred and sparks are apparent. Carbon black that has been on fire should be observed closely for at least 48 hours to ensure no smouldering material is present.
Precautions for Fire Fighters and Special Protective Equipment :
Wear full protective fire fighting gear including self-contained breathing apparatus (SCBA) for protection against possible exposure.
Closed containers exposed to fire may be cooled with water.
SECTION 6. ACCIDENTAL RELEASE MEASURES
Wear appropriate Personal Protective Equipment and respiratory protection.
Methods and Materials for Containment and Clean-up Procedures :
Small spills Should be vacuumed when possible. Dry sweeping is not recommended due to the creation of dust in the atmosphere. A vacuum equipped with HEPA (high efficiency particulate air) filtration is recommended. If necessary, light water spray will reduce dust for dry sweeping.
Large Spills Evaluate the possibility of recovering and reusing the material. Large spills may be shovelled into containers.
Environmental Carbon black poses no significant environmental hazards. As a matter of Precautions good practice, minimise contamination of sewerage water, soil, groundwater, and storm water or any other drainage systems or bodies of water.
SECTION 7. HANDLING & STORAGE
Handling:
Avoid dust exposures above the occupational exposure limit. Wash exposed skin daily. Use local exhaust ventilation to control exposures to below occupational exposure limit. Fine dust may cause electrical shorts and is capable of penetrating electrical equipment unless tightly sealed. If hot work (welding, torch cutting,etc.) is required the immediate work area must be cleared of carbon black product and dust.
Storage:
Store in dry place away from ignition sources and strong oxidizers. Before
entering closed vessels and confined spaces containing carbon black test for adequate oxygen, flammable gases and potential toxic air contaminants (e.g.,CO). Follow safe practices when entering confined spaces.
SECTION 8. EXPOSURE CONTROLS / PERSONAL PROTECTION
Maximum carbon black dust content in air by U.S. standards is 3.5 mg/m3, by German standards 6 mg/m3, by U.K. standards 3,5 mg/m3.
Engineering Controls:
Use process enclosures and/or exhaust ventilation to keep airborne dust concentrations below the occupational exposure limit.
PERSONAL PROTECTIVE EQUIPMENT:
Eye/Face Protection:
No special eye protection is normally required. Where splashing is possible, wear safety glasses with side shields as a good safety practice.
Skin Protection:
Wear impervious protective clothing to prevent skin contact. Selection of protective clothing may include gloves, apron, boots, and complete facial protection depending on operations conducted. Users should determine acceptable performance characteristics of protective clothing. Consider physical requirements and other substances present when selecting protective clothing. Suggested materials for protective gloves include: No skin protection is ordinarily required under normal conditions of use.
Respiratory Protection: Wear a NIOSH approved respirator that provides protection when working with this material if exposure to harmful levels of airborne material may occur, such as: Air-Purifying Respirator for Dusts and Mists.
