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.
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.
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.
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.
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.
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.
