Potential Health Effects
----------------------------------
Inhalation:Inhalation of dusts of a comparable compound may cause irritation to the respiratory tract and cause moderate systemic effects such as methemoglobinemia by absorption.
Ingestion:Comparable compounds are moderately toxic by ingestion and can cause blood circulation problems.
Skin Contact:Comparable compounds are skin irritants. This compound is probably an irritant and may be absorbed through skin.
Eye Contact:Probably an irritant to eyes.
Chronic Exposure:Prolonged or repeated exposure from inhalation or skin absorption of liquid may cause damage to the nervous system, liver, kidneys, and bone marrow. May also cause weight loss, anemia, weakness, and irritability.
Aggravation of Pre-existing Conditions:Persons with pre-existing skin disorders or eye problems, or impaired liver, kidney or respiratory function may be more susceptible to the effects of the substance.


4. First Aid Measures

Procedures that parallel those of diphenylamine (CAS #122-39-4) will be discussed.
Inhalation:If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. CALL A PHYSICIAN IMMEDIATELY.
Ingestion:Induce vomiting immediately as directed by medical personnel. Never give anything by mouth to an unconscious person.
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 reuse. Thoroughly clean shoes before reuse. Get medical attention immediately.
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: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

Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Pick up and place in a suitable container for reclamation or disposal, using a method that does not generate dust.


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.


8. Exposure Controls/Personal Protection

Airborne Exposure Limits:
For Diphenylamine [122-39-4]:
-OSHA Permissible Exposure Limit (PEL): 10 mg/m3 (TWA)

-ACGIH Threshold Limit Value (TLV): 10 mg/m3 (TWA)
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, a half facepiece particulate respirator (NIOSH type N95 or better filters) may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest.. A full-face piece particulate respirator (NIOSH type N100 filters) may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. If oil particles (e.g. lubricants, cutting fluids, glycerine, etc.) are present, use a NIOSH type R or P filter. 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. An OV/particluate (NIOSH type N95 filter or better) respirator may be preferable when odor is a problem.
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.
