| Hazards and Protection. | |
| Storage | Keep away from sources of ignition. Store in a cool, dry place. Store in a tightly closed container. Keep from contact with oxidizing materials. |
| WHMIS | D2A |
| Handling | Use with adequate ventilation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. |
| Protection | Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate gloves to prevent skin exposure. Clothing: Wear appropriate protective clothing to minimize contact with skin. |
| Respirators | Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. |
| Small spills/leaks | Vacuum or sweep up material and place into a suitable disposal container. Avoid generating dusty conditions. |
| Stability | Stable under normal temperatures and pressures. |
| Incompatibilities | May react vigorously or violently when mixed with strong oxidizing agents such as chlorates, bromates and nitrates, especially when heated. Incompatible with chlorinated paraffins, lead oxide, manganese oxide, iron oxide, liquid oxygen, oils, and moisture. . |
| Decomposition | Carbon monoxide, carbon dioxide. |
| Fire. | ||||
| Autoignition, °C | 449 | |||
| Fire fighting | Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. Dust can be an explosion hazard when exposed to heat or flame. Flammable solid. Can be easily ignited and burns vigorously. Extinguishing media: For small fires, use water spray, dry chemical, carbon dioxide or chemical foam. | |||
| Fire potential | Slight risk when exposed to heat or flame. Carbon black can be ignited in the presence of open flames, and burns slowly with production of carbon monoxide. | |||
| Combustion products | Toxic vapors and gases (e.g. carbon monoxide) may be released in a fire involving carbon black. | |||
| Health. | |

| Poison_Class | - |
| Exposure effects | There are no human or animal reports suggesting a teratogenic potential for carbon black. |
| Ingestion | Ingestion of large amounts may cause gastrointestinal irritation. |
| Inhalation | Dust is irritating to the respiratory tract. |
| Skin | May cause skin irritation. |
| Eyes | Causes eye irritation. |
First aid |
|
| Ingestion | If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid. |
| Inhalation | Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. |
| Skin | Get medical aid if irritation develops or persists. Flush skin with plenty of soap and water. |
| Eyes | Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. |
