Potential Health Effects
---------------------------
Health effects from exposure to phenylhydrazine hydrochloride are expected to
parallel those from exposure to Phenylhydrazine. The health effects form
exposure to phenylhydrazine are given below. All routes of exposure can produce
hemolytic anemia (breakdown of the red blood cells) with resultant injury to
liver and kidneys. May cause methemoglobinemia.
Inhalation: Poison. Corrosive to the respiratory tract. May produce sore
throat, coughing, labored breathing, dizziness, bluish skin, faintness.
Ingestion: Toxic. May be fatal if swallowed. Corrosive to tissues. May
cause vomiting, dizziness, faintness, and jaundice.
Skin Contact:Corrosive. Contact dermatitis and skin sensitization may
occur. Other symptoms include redness, pain, burns; skin absorption can happen
readily and produce toxic effects noted for inhalation and ingestion.
Eye Contact:Corrosive. Any eye contact is destructive to eye tissue.
Chronic Exposure:Chronic and acute exposures may produce blood effects,
liver and kidney damage. Phenylhydrazine is a possible cancer hazard based on
animal data.
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.
Upon poisoning by PHENYLHYDRAZINE, specific first aid and
treatment are essential. Get Immediate Medical Attention For Any Exposure.
Inhalation:Remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Call a physician.
Ingestion:If swallowed, DO NOT INDUCE VOMITING. Give large quantities of
water. Never give anything by mouth to an unconscious person. Get medical
attention immediately.
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, immediately. 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.
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.
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. US Regulations (CERCLA) require reporting spills and releases to soil, water and air in excess of reportable quantities.
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. Isolate from incompatible substances. 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.
Airborne Exposure Limits:
For Phenylhydrazine:
-OSHA Permissible Exposure Limit (PEL):
5 ppm (TWA), 10 ppm (STEL) skin
-ACGIH Threshold Limit Value (TLV):
0.1 ppm (TWA) skin, category A2, suspect human carcinogen.
-NIOSH recommended exposure limit (REL):
0.6 mg/m3/2H, ceiling concentration
Ventilation System:
A system of local and/or general exhaust is recommended to keep employee
exposures below the Airborne Exposure Limits. 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.
