Potential Health Effects
----------------------------------
REAGENTS, INC.-- MSDS--ALPHA-NAPHTHOL PAGE -2-
Inhalation: Causes irritation to the respiratory tract. Symptoms may include coughing, shortness of
breath. Inhalation may result in symptoms and problems similar to ingestion. Experimental animal
studies with this compound suggest inhalation exposure may be fatal.
Ingestion: Large doses may cause crampy abdominal pain, nausea, vomiting, sweating, intense thirst,
cyanosis, hyperactivity, stupor, liver damage, blood pressure fall, nephritis, diarrhea, circulatory
collapse, anemia, convulsions, and death. Estimated lethal dose 5 grams.
Skin Contact: May cause severe irritation, redness, and pain. May be absorbed through the skin with
symptoms paralleling ingestion and causing kidney damage. Local action may cause peeling of the skin
which may be followed by persistent pigmentation.
Eye Contact: Causes irritation, redness, pain, and injury to the cornea and lens of the eyes.
Chronic Exposure: Prolonged or repeated skin exposure may cause dermatitis and symptoms similar to
acute exposure. Repeated ingestion may also cause symptoms similar to acute exposure.
Aggravation of Pre-existing Conditions: No information found.
4. First Aid Measures
Inhalation: Remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention immediately.
Ingestion: Induce vomiting immediately as directed by medical personnel. Never give anything by
mouth to an unconscious person. Get medical attention.
Skin Contact: Immediately flush skin with plenty of soap and water for at least 15 minutes while
removing contaminated clothing and shoes. Get medical attention. Wash clothing before reuse.
Thoroughly clean shoes before reuse.
Eye Contact: Immediately flush eyes with plenty of water for at least 15 minutes, lifting lower and upper
eyelids occasionally. Get medical attention immediately.
5. Fire Fighting Measures
Fire: As with most organic solids, fire is possible at elevated temperatures or by contact with an ignition
source.
Explosion: Not considered to be an explosion hazard.
Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or carbon dioxide.
Special Information: Use protective clothing and breathing equipment appropriate for the surrounding
fire.
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. Do not
flush to the sewer.
7. Handling and Storage
REAGENTS, INC.-- MSDS--ALPHA-NAPHTHOL PAGE -3-
Keep in a tightly closed light-resistant container, stored in a cool, dry, ventilated area. Protect against
physical damage. Isolate from any source of heat or ignition. Isolate from oxidizing materials.
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.
8. Exposure Controls/Personal Protection
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 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 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.
