Potential Health Effects
----------------------------------
Inhalation:
Inhalation has a narcotic effect. Symptoms include headache, dizziness,
nausea and dullness. Following exposures of high concentrations, victim may
become unconscious, and if exposure is not terminated, death can result
from respiratory failure.
Ingestion:
Abdominal pain, vomiting, diarrhea, visual disturbances, dizziness and
unconsciousness can occur. Severe gastrointestinal upset progressing to
serious kidney and liver damage can occur. Death can occur immediately or
be delayed for as much as one week.
Skin Contact:
Can be absorbed through skin, with symptoms paralleling ingestion exposure.
A dermatitis may be produced following long or repeated contact. Skin oils
are removed upon contact, and the skin becomes red, cracked, and dry.
Eye Contact:
Severe irritant as vapor or liquid. Symptoms of burning and intense
irritation occur.
Chronic Exposure:
Affects nervous system. Delayed effects from exposure include damage to the
heart, liver and kidneys. Repeated or prolonged exposures may cause skin
irritation, optic nerve damage with possible blindness, and hearing loss.
Symptoms of darkened urine and liver cirrhosis have been reported.
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
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
immediately.
Skin Contact:
Immediately flush skin with plenty of 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.
Note to Physician:
To minimize hepatorenal damage, consider intravenous acetylcysteine.
Hyperbaric oxygen is also utilized for significant exposures. Dialysis has
also been suggested in severe cases. Give cardiorespiratory support as
indicated and carefully monitor fluid and electrolytes. Closely monitor
hepatic and renal functions. Avoid epinephrine because of myocardial
sensitization and potential for inducing ventricular arhythymias.
5. Fire Fighting Measures
Fire:
Not considered to be a fire hazard. Under fire conditions, produces
hydrochloric acid and phosgene.
Explosion:
Not considered to be an explosion hazard.
Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.
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
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
(vapors, liquid); observe all warnings and precautions listed for the
product.
8. Exposure Controls/Personal Protection
Airborne Exposure Limits:
- OSHA Permissible Exposure Limit (PEL):
10 ppm (TWA); ceiling = 25 ppm, maximum 200 ppm (5-minute maximum peak in
any 4 hours);
- ACGIH Threshold Limit Value (TLV):
5 ppm (TWA), 10 ppm (STEL), skin; A2 suspected human carcinogen
- NIOSH Recommended Expoisure Limits (RELs):
2 ppm, 60-minute (STEL).
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, wear a supplied air, full-facepiece
respirator, airlined hood, or full-facepiece self-contained breathing
apparatus.
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 a full face shield where splashing is
possible. Maintain eye wash fountain and quick-drench facilities in work
area.
