This document is a material safety data sheet for Black Slurry produced by New Riverside Ochre Company. It describes the product as a water-based pigment slurry containing carbon black, umber, and chemical additives. The slurry poses little immediate hazard but may cause slight skin or eye irritation if contact occurs. Proper personal protective equipment should be used if exposure limits are exceeded. The slurry is stable and not hazardous unless airborne dust levels exceed recommended limits, in which case ventilation is necessary to control exposure.

The pigment components range from 35% to 55% by solids of the finished product depending on color.
The chemical additives range from 8% to 12% of the wet slurry weight. The range of colors offered are
combinations of the natural and synthetic iron oxides and the chemical additives to produce consistent
and stable color. The three chemical additives include an anionic polymer, a potassium salt of
phosphated alcohol ethoxylate and sodium polyacrylate.

POTENTIAL HEALTH EFFECTS:
INHALATION: In a dry form, inhalation of the dust may cause mechanical irritation to the respirator tract.
Excessive exposure above the TLV can give mild pulmonary irritation. Long term overexposure to silica
causes silicosis. This product is considered a carcinogen by IARC because it contains crystalline silica at
levels greater than 0.1%.
EYE CONTACT: Flush eyes with large amounts of water until irritation subsides. If irritation persists, get
medical attention.
SKIN CONTACT: Not absorbed by the body. Skin contact may cause mechanical irritation due to
abrasion. Wash with soap and water. Get medical attention if irritation develops.
INGESTION: May be harmful if swallowed; non-toxic.
CHRONIC: N/A
4. FIRST AID MEASURES
INHALATION: Remove victim from the area where TLV has been exceeded. If victim is not breathing,
give artificial respiration. Call a physician. Remediate work area as described in Section 8.
EYE CONTACT: Flush eyes with large amounts of water until irritation subsides. If irritation persists, get
medical attention.
SKIN CONTACT: Wash with soap and water. Get medical attention if irritation develops.
INGESTION: If conscious, give large quantities of water. Get medical attention.
5. FIREFIGHTING MEASURES
FLASHPOINT: Non-flammable.
EXTINGUISHING MEDIA: As appropriate for surrounding combustibles. Product does not burn or support
combustion. Not a fire or explosion hazard.
FIREFIGHTING EQUIPMENT: Respiratory and eye protection required for firefighting personnel.
6. ACCIDENTAL RELEASE MEASURES
GENERAL: Refer to local, State or Federal regulations for specific disposal information. Pursuant to 40
CFR Part 261 of the Resources Conservation and Recovery Act (RCRA) regulations currently in effect,
discarded iron oxide would not be classified as a hazardous waste.
LAND SPILL: Vacuum or scoop up spilled material for recovery or disposal.
WATER SPILL: Product is inert and stable. Decomposition and polymerization will not occur.
7. HANDLING AND STORAGE
Slurry should be stored above 32°F. Gentle agitation may be needed if stored for an extended period.
GENERAL: Maintain packaging intact until ready for use. See Section 8.

8. EXPOSURE CONTROL / PERSONAL PROTECTION
ENGINEERING CONTROLS: Use process enclosures, local exhaust ventilation or other engineering
controls to control airborne levels below recommended exposure limits. Provide mechanical ventilation of
confined spaces.
PERSONAL PROTECTION:
EYE PROTECTION: Safety glasses or tight goggles.
SKIN PROTECTION: Rubber, cloth or plastic gloves if appropriate for job conditions.
RESPIRATOR: If exposure limits are exceeded, an appropriate NIOSH dust respirator should be used.
9. PHYSICAL AND CHEMICAL PROPERTIES
Water-based slurry of 40% to 60% inert iron oxide pigmenting agents.
10. STABILITY AND REACTIVITY
GENERAL: This product is stable and hazardous polymerization will not occur.
INCOMPATIBLE MATERIALS AND CONDITIONS TO AVOID: None.
HAZARDOUS DECOMPOSITION: None.
11. REGULATORY INFORMATION
DISPOSAL: Iron oxides are not hazardous waste per 40 CFR Part 261.24 or Part 261.3. However, the
user should consult with the State environmental regulatory agency before disposing of this material.
