LD50 LC50 Mixture:BORIC ACID/LD50=3450 MIL/KG
Routes of Entry: Inhalation:YES Skin:YES Ingestion:YES
Reports of Carcinogenicity:NTP:YES IARC:YES OSHA:YES
Health Hazards Acute and Chronic:PRIMARY ROUTES OF EXPOSURE ARE
INHALATION OF FUMES, GASES OF PARTICULATE AND INGESTION OF
PARTICULATE. ABSORPTION THROUGH SKIN NOT LIKELY. CHRONIC EXPOSURE
TO COPPER, ZINC AND MANGANESE MAY CAUSE META L FUME FEVER. SYMPTOMS
OF METAL FUME FEVER INCLUDE FEVER, DRYNESS OF THROAT, HEAD AND BODY
ACHE AND CHILL. CHRONIC EXPOSURE MAY AFFECT CENTRAL NERVOUS SYSTEM
LEADING TO EMOTIONAL DISTURBANCES, GAIT AN D BALANCE DIFFICULTIES
OR PARALYSIS. OVEREXPOSURE TO COPPER MAY RESULT IN SKIN AND HAIR
DISCOLORATION. NICKEL HAS BEEN IDENTIFIED AS POTENTIAL CANCER
CAUSING AGENT. GASEOUS REACTION PRODUCTS MAY INCL UDE CARBON
MONOXIDE AND CARBON DIOXIDE.
Explanation of Carcinogenicity:CHROMIUM AND NICKEL MUST BE CONSIDERED A
POSSIBLE CARCINOGEN UNDER OSHA 29CFR1910.1200. IARC HAS INDICATED
THAT CHROMIUM AND NICKEL & CERTAIN OF ITS COMPOUNDS ARE PROBABLY
CARCINOGENIC FOR HUMANS, BUT THE COMPOUNDS CANNOT BE SPECIFIED
PRECISELY.
Effects of Overexposure:SHORT TERM (ACUTE) OVEREXPOSURE TO WELDING
FUMES CAN LEAD TO SIDEROSIS (IRON DEPOSITS IN LUNG) AND AFFECT
PULMONARY FUNCTION. ARC RAYS CAN INJURE EYES AND BURN SKIN. HEAT
RAYS (INFARED RADIATING FROM FLAME OF HOT METAL CAN INJURE EYES.
ELECTRIC SHOCK CAN KILL. NOISE CAN DAMAGE HEARING.
Medical Cond Aggravated by Exposure:PRE-EXISTING MEDICAL CONDITIONS
INDIVIDUALS WITH IMPARIRED RESPIRATORY FUNCTION MAY HAVE SYMPTOMS
WORSENED BY EXPOSURE TO WELDING FUMES.

First Aid:CALL FOR MEDICAL AID. EMPLOY FIRST AID TECHNIQUES RECOMMENDED
BY THE AMERICAN RED CROSS. IF BREATHING IS DIFFICULT, GIVE OXYGEN.
CALL A PHYSICIAN. IN CASE OF ELECTRIC SHOCK, DISCONNECT AND TURN
OFF PO WER. IF NOT BREATHING, GIVE ARTIFICIAL RESPIRATIN,
PREFERABLY MOUTH TO MOUTH. IF DETECTABLE PULSE, BEGIN EXTERNAL
HEART MASSAGE. IMMEDIATELY CALL A PHYSICIAN. IN CASE OF ARC OF
FLAME BURN. CALL A PHYS ICIAN.

Flash Point:NONFLAMMABLE
Extinguishing Media:WELDING ARC AND SPARKS CAN IGNITE COMBUSTIBLE AND
FLAMMABLE PRODUCTS. SEE ANSI 49.1 "SAFETY IN WELDING & CUTTING"
(REFERENCED IN SECTION VII) FOR FIRE PROTECTION INFORMATION.
Fire Fighting Procedures:NEVER USE WATER AS AN EXTINGUISHING AGENT
AROUND MOLTEN METAL.
Unusual Fire/Explosion Hazard:UNUSUAL FIRE AND EXPLOSION HAZARDS: NONE
BUT MATERIAL MAY REACT WITH ACIDS, BASES, OR OXIDIZERS. MATERIAL
DOES NOT PRESENT A SIGNIFICANT HEALTH HAZARD UNDER NORMAL HANDLING
AND STORAGE CONDITIONS.

Handling and Storage Precautions:READ AND UNDERSTAND THE MANUFACTURER'S
INSTRUCTIONS AND THE PRECAUTIONARY LABEL ON THE PRODUCT. SEE
AMERICAN NATIONAL STANDARD Z49.1. SAFETY IN WELDING AND CUTTING,

FL 33135; OSHA PUBLICATION 2206 (29CFR1910).
Other Precautions:THE ACGIH 1984-85 RECOMMENDED PERMISSIBLE LIMIT FOR
WELDING FUME, NOT OTHERWISE CLASSIFIED, IS 5 MG/CUBIC METER

Respiratory Protection:TRAIN THE WELDER TO KEEP HIS HEAD OUT OF THE
FUMES. USE RESPIRABLE FUME RESPIRATOR OR AIR-SUPPLIED RESPIRATOR
WHEN WELDING IN CONFINED SPACE OF WHERE LOCAL EXHAUST OF
VENTILATION DOES NOT KEEP EXPOSUR E BELOW TLV. SELECT AS PER OSHA
29 CFR 1910.134.
Ventilation:USE ENOUGH VENTILATION, LOCAL EXHAUST AT THE ARC, OR BOTH,
TO KEEP THE FUMES AND GASES BELOW TLV'S IN THE WORKER'S BREATHING
ZONE AND THE GENERAL AREA.
Protective Gloves:WELDER'S GLOVES.
Eye Protection:WEAR HELMET OR USE FACE SHIELD WITH FILTER LENS.
Other Protective Equipment:WEAR HAND, HEAD AND BODY PROTECTION WHICH
HELP TO PREVENT INJURY FROM RADIATION, SPARKS, AND ELECTRIC SHOCK.
SEE ANZI 49.1. AT MINIMUM THIS INCLUDES WELDER'S GLOVES, PROTECTIVE
FACE SHIELD.
