Potential Health Effects
----------------------------------
Inhalation: Dust is mildly irritating to throat and lungs because of
hydrochloric acid.
Ingestion: Toxic effects not fully understood. Extremely large oral
dosages may produce gastrointestinal disturbances. May create a bladder
irritation. Material is slightly acidic.
Skin Contact: May cause irritation. Skin absorption may occur, but the
toxic effects are not well known.
Eye Contact: May cause eye irritation.
Chronic Exposure: No information found.
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: 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. Remove 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 upper and lower eyelids occasionally. Get medical
attention if irritation persists.
5. Fire Fighting Measures
Fire: As with most organic solids, fire is possible at elevated
temperatures or by contact with an ignition source.
Explosion: Fine dust dispersed in air in sufficient concentrations, and
in the presence of an ignition source is a potential dust explosion hazard.
Fire Extinguishing Media: Water spray, dry chemical, alcohol foam, or
carbon dioxide.
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.
7. Handling and Storage
Keep in a tightly closed container. Protect from physical damage. Store in a
cool, dry, ventilated area away from sources of heat, moisture and
incompatibilities. Wear special protective equipment (Sec. 8) for maintenance
break-in or where exposures may exceed established exposure levels. Wash
hands, face, forearms and neck when exiting restricted areas. Shower, dispose
of outer clothing, change to clean garments at the end of the day. Avoid
cross-contamination of street clothes. Wash hands before eating and do not
eat, drink, or smoke in workplace. 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: Similar compound o-Toluidine is ACGIH listed
as a
suspect carcinogen with a TLV of 2 ppm skin -OSHA Permissible Exposure Limit
(PEL):
5 ppm skin for 0-Toluidine
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): If the exposure limit is
exceeded and engineering controls are not feasible, wear a supplied air,
full-facepiece respirator, airlined hood, or full-facepiece self-contained
breathing apparatus. Breathing air quality must meet the requirements of the
OSHA respiratory protection standard (29CFR1910.134).
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. Maintain eye wash fountain
and quick-drench facilities in work area.
