===================== Hazards Identification =====================
Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:YES IARC:YES OSHA:NO
Health Hazards Acute and Chronic:REPEAT/PROLONG CONTACT MAY CAUSE
CHLORACNE IN SOME PEOPLE.SKIN:ABSROBED THRU INTACT SKIN.LOC ACTION
SIMILAR TO COMMON ORG SOLVENTS-REMOVES NATURAL FATS/OILS RESULTING
IN DRYING/CRACKING.EYE:MODERATELY IRRIT.INGEST:SLIGHTLY
TOXIC.INHAL:ANIMAL EXPERIMENTS SHOWED 54% CHLORINATED MATL PRODUCES
MORE LIVER INJURY THAN 42%.
Explanation of Carcinogenicity:PER MSDS:PCBS HAVE BEEN LISTED IN IARC
GROUP 2B & IN NTP.
Effects of Overexposure:CHLORACNE. DRYING & CRACKING SKIN. MODERATELY
EYE IRRITANT. SLIGHTLY TOXIC BY INGEST. LIVER INJURY.
Medical Cond Aggravated by Exposure:A POTENTIAL EXISTS FOR CONTRACTING
OF CHLORACNE IN SOME PEOPLE.
======================= First Aid Measures =======================
First Aid:INGEST:CONSULT PHYSICIAN.DO NOT INDUCE VOMIT OR GIVE ANY OILY
LAXATIVES.SKIN:IF LIQ/SOLID PCBS SPLASHED/SPILLED ON SKIN REMOVE
CONTAMIN CLOTH.WASH SKIN THOROUGHLY W/SOAP/WATER.EYES:IRRIGATE
IMMED W/CO PIOUS QUANT OF RUNNING WTER FOR @LEAST
15MINS.PETROLATUM-BASED OPHTHALMIC OINTMENT MAY BE APPLIED TO
RELIEVE IRRIT EFFECTS.INHAL:REMOVE TO FRESH AIR.IF RASH/RESP IRRIT
PERSIST CALL PHYSICIAN.(SUPPLEM)
===================== Fire Fighting Measures =====================
Flash Point:FIRE-RESISTANT
Extinguishing Media:PCBS ARE FIRE-RESISTANT COMPOUNDS.
Fire Fighting Procedures:STD FIREFIGHTING WEARING APPAREL & SCBA SHOULD
BE WORN WHEN FIGHTING FIRES THAT INVOLVE POSSIBLE EXPO TO CHEM
COMBUST PROD.CLEAN WELL/DECONTAMIN EQMPT AFT USE.
Unusual Fire/Explosion Hazard:IF PCB TRANSFORMER INVOLVED IN
FIRE-RLATED INCIDENT OWENR OF TRANSFORMER MAY BE REQUIRED TO REPORT
