3. Hazards Identification



 Emergency Overview

 --------------------------

 WARNING! ACTIVATED CARBON AFFECTS THE RESPIRATORY AND

CARDIOVASCULAR SYSTEMS.



 CAUTION!!! Wet activated carbon removes oxygen from air causing a severe

 hazard to workers inside carbon vessels and enclosed or confined spaces.

 Before entering such an area, sampling and work procedures for low oxygen

 levels should be taken to ensure ample oxygen availability, observing all

 local, state, and federal regulations.

 Inhalation:



 May cause mild irritation to the respiratory tract. The acute inhalation LC50

 (Rat) is >64.4 mg/l (nominal concentration) for activated carbon.



 Ingestion:



 No adverse effects expected. May cause mild irritation to the gastrointestinal

 tract. The acute oral LD50 (Rat) is >10g/kg.



 Skin Contact:



 Not expected to be a health hazard from skin exposure. May cause mild

 irritation and redness. The primary skin irritation index (Rabbit) is 0.



 Eye Contact:



 No adverse effects expected. May cause mild irritation, possible reddening.



 Chronic Exposure:



 Prolonged inhalation of excessive dust may produce pulmonary disorders. The

 effects of long-term, low-level exposures to this product have not been

 determined. Safe handling of this material on a long-term basis should

 emphasize the avoidance of all effects from repetitive acute exposures.



 Aggravation of Pre-existing Conditions:



 No information found.



4. 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, seek medical attention.



 Skin Contact:



 Not expected to require first aid measures. Wash exposed area with soap and

 water. Seek medical attention if irritation develops.



 Eye Contact:

MSDS for Activated Carbon                                                   Page 3 of 7

 Wash thoroughly with running water for at least 15 minutes. Seek medical

 attention if irritation develops.



5. Fire Fighting Measures



 Fire Extinguishing Media: Water or water spray.



 Unusual Fire and Explosion Hazards:



 Contact with strong oxidize such as ozone, liquid oxygen, chlorine,

 permanganate, etc., may result in fire.



 Special Information:



 In the event of a fire, wear full protective clothing and NIOSH-approved

 self-contained breathing apparatus with full facepiece operated in the

 pressure demand or other positive pressure mode.



6. Accidental Release Measures



 Remove all sources of ignition. Ventilate area of leak or spill. Wear

 appropriate personal 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 and 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.



7. Handling and Storage



 Protect against physical damage. Store in a cool, dry well-ventilated

 location, away from any area where the fire hazard may be acute. Outside or

 detached storage is preferred. Separate from incompatibles. Containers should

 be bonded and grounded for transfers to avoid static sparks. Storage and use

 areas should be No Smoking areas. Use non-sparking type tools and equipment,

 including explosion proof ventilation. Containers of this material may be

 hazardous when empty since they retain product residues (dust, solids);

 observe all warnings and precautions listed for the product.

 CAUTION!! Wet activated carbon removes oxygen from air causing a severe hazard

 to workers inside carbon vessels and enclosed or confined spaces. Before

 entering such an area, sampling and work procedures for low oxygen levels

 should be taken to ensure ample oxygen availability, observing all local,

 state, and federal or national regulations.



8. Exposure Controls/Personal Protection



 Exposure Guidelines:



 OSHA PEL*: 5mg/M3 (Respirable)

MSDS for Activated Carbon                                                   Page 4 of 7

 ACGIH TLV*: 10 mg/M3 (Total)



 *PELs and TLVs are 8-hour TWAs unless otherwise noted.



 Ventilation System:



 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. Please

 refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended

 Practices, most recent edition, for details.



 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 atmospheres.



 Skin Protection:



 Wear protective gloves and clean body-covering clothing.



 Eye Protection:



 Use chemical safety goggles. Maintain eye wash fountain and quick-drench

 facilities in work area.
