Potential Health Effects
----------------------------------
Inhalation:
Irritation of mucous membranes.
Ingestion:
Stomach pains vomiting, diarrhea.
Skin Contact:
Irritation, May be absorbed through the skin with possible systemic effects.
Eye Contact:
Irritation, with discomfort, tearing.
Chronic Exposure:
No information found.
Aggravation of Pre-existing Conditions:
No information found.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Prompt action is essential.
Ingestion:
Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention.
Skin Contact:
In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Thorough cleansing of the entire contaminated area of the body including scalp and nails is of the utmost importance.
Eye Contact:
Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention.
Fire:
Not expected to be a fire hazard.
Explosion:
Emits toxic fumes under fire conditions.
Fire Extinguishing Media:
Use water spray, carbon dioxide, dry chemical powder or appropriate foam.
Special Information:
Firefighters should wear proper protective equipment and self-contained breathing apparatus with full facepiece operated in positive pressure mode. The protective clothing should prevent contact with skin and eyes.
Evacuate area. Wear self-contained breathing apparatus, rubber boots and heavy rubber gloves. Wear disposable coveralls and discard them after use. Sweep up, place in a bag, and hold for waste disposal. Avoid raising dust. Ventilate area and wash spill site after material pickup is complete.
Keep container tightly closed. Store in cool, dry, well-ventilated area away from heat, sparks, or flame. Handling operations should be conducted in a chemical fume hood. Do not add any other material to the container. Do not wash down the drain. Do not allow smoking and food consumption while handling. Do not get in eyes, on skin, or on clothing. Wash thoroughly after use. Since empty container retains product residue, follow label warnings even after container is empty.
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.
