Potential Health Effects
----------------------------------
Inhalation:
Is harmful
Ingestion:
Is harmful
Skin Contact:
Severe irritation or burns.
Eye Contact:
Severe irritation or burns.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
Damaged skin.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Prompt action is essential.
Ingestion:
If swallowed, DO NOT INDUCE VOMITING. Give large quantities of water. Never give anything by mouth to an unconscious person. Get medical attention immediately.
Skin Contact:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Wash clothing before re-use.
Eye Contact:
In case of eye contact, immediately flush with plenty of water for at least 15 minutes.
Fire:
Not expected to be a fire hazard.
Explosion:
Contact with acids may generate spontaneously flammable chlorine dioxide gas. Greatly increases the burning rate of combustible materials. Fire or excessive heat may produce hazardous decomposition products. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion
Fire Extinguishing Media:
Use extinguishing media appropriate for surrounding fire.
Special Information:
Wear self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes. Firefighters should wear proper protective equipment and self-contained breathing apparatus with full facepiece operated in positive pressure mode. Move exposed containers from fire area if it can be done without risk. Use water to keep fire-exposed containers cool. Fight fire from protected location
Flush to sewer with large amounts of water.
Material is a strong oxidizer. Keep from contact with clothing and other combustible materials. Remove and wash contaminated clothing promptly. Do not store near combustible materials. Store in tightly closed container. Since empty container may retain product residue, follow label warnings even after container is empty. Keep away from fire. Fire or high temperatures may cause explosive decomposition.
Airborne Exposure Limits:
None established.
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee exposures as low as possible. 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 substance is apparent and engineering controls are not feasble, consult an industrial hygienist. For emergencies, or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air purifying respirators do not protect workers in oxygen-deficient atmospheres.
Skin Protection:
Wear impervious protective clothing, including boots, gloves, lab coat, apron or coveralls, as appropriate, to prevent skin contact.
Eye Protection:
Use chemical safety goggles and/or full face shield where dusting or splashing of solutions is possible. Maintain eye wash fountain and quick-drench facilities in work area.
