Caution ! Activated Carbon affects the Respiratory and Cardiovascular systems.
Potential Health Effect
Inhalation : No adverse effects expected. May cause mild irritation to the respiratory tract.
Ingestion : No adverse effects expected. May cause mild irritation to the gastrointestinal tract.
Skin Contact : Not expected to be a health hazard from skin exposure. May cause mild irritation and redness.
Eye Contact : No adverse effects expected. May cause mild irritation, possible reddening.
Chronic Exposure : Prolonged inhalation of excessive dust may produce pulmonary disorders.
First Aid Measures
Inhalation : Remove to fresh air. Get medical attention for any breathing difficulty.
Ingestion : Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice.
Skin Contact : Not expected to require first aid measures. Wash exposed area with soap & water. Get medical advice if irritation develops.
Eye Contact : Wash thoroughly with running water. Get medical advice if irritation develops.
Fire Fighting Measures
Fire : As with most organic solids, fire is possible at elevated temperature or by contact with an ignition source. Activated carbon is difficult to ignite and tends to burn slowly (smolder) without producing smoke or flame. Wet Activated Carbon depletes oxygen from the air materials. Allowed to smolder for long periods in enclosed spaces, may produce amounts of carbon monoxide which, may reach the lower explosive limit for carbon monoxide of 12.5% in air, contact with strong oxidizers such as ozone or liquid oxygen may cause rapid combustion.
Explosion : Fine dust dispersed in air in sufficient concentrations and in the presence of an ignition source is a potential dust explosion hazard. Minimum explosible concentration 0.140 g/l.
Fire Extinguishing Media :
Water spray, dry chemical, alcohol foam or carbon dioxide.
Special information :
In the event of a fire, wear full protective clothing NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Remove all sources of ignition. Ventilate area of leak or spill. Wear appropriate person protective equipment as specified in Section 8. Spills: Clean up spills in a manner that does not disperse dust into the air. Use non-sparking tools & equipment. Reduce airborne dust and prevent scattering by moistening with water. Pick up spill for recovery or disposal and place in a closed container. Warning! Spent product may have absorbed hazardous materials.
Handling and Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Keep away from moisture & oxidizers. Avoid dust dispersal. Wet activated carbon deplets oxygen from the air and therefore dangerously low levels of oxygen may be encountered in confined spaces. Work procedures for potentially low oxygen areas should be followed. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warning & precautions listed for the product.
Exposure Controls / Personal Protection
Airborne Exposure Limits
OSHA Permissible Exposure Limits(PELs) : Activated Carbon (graphite, synthetic) : total particulate = 15 mg/m3 (TWA), respirable fraction = 5 mg/m3 (TWA)ACGIH Threshold Limit Values (TLVs) : Graphite, all forms except graphite fibers: 2 mg/m3 (TWA)
A system of local and/or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area.
Personal Respirators (NIOSH Approved)
For conditions of use where exposure to the dust or mist is apparent, a half-face dust/mist respirator may be worn. For emergencies or instances where the exposure levels are not known, use a full-face positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen deficient atmosphere.
Wear protective gloves and clean body – covering clothing.
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
