SECTION 03: HAZARDS IDENTIFICATION
------------------------------------------------------------------------------
ROUTE OF ENTRY:....................
SKIN CONTACT.................CAUSES CHEMICAL BURNS. BOTH LIQUID AND
VAPOUR CAN CAUSE SEVERE BURNS WHICH MAY
NOT BE IMMEDIATELY PAINFUL OR VISIBLE.
PRODUCT WILL PENETRATE SKIN AND ATTACK
UNDERLYING TISSUES AND BONE.LARGE BURNS
(OVER 25 SQUARE INCHES) MAY ALSO CAUSE
HYPOCALCEMIA (DEPLETION OF CALCIUM IN THE
BODY) AND OTHER TOXIC EFFECTS WHICH MAY BE
FATAL.SOLUTIONS AS DILUTE AS 2% OR LOWER
MAY CAUSE BURNS WITH PROLONGED CONTACT.
SKIN ABSORPTION..............MAY BE ABSORBED BY THE SKIN.
EYE CONTACT..................BOTH LIQUID AND VAPOUR CAN CAUSE
IRRITATION OR CORNEAL BURNS.SOLUTIONS AS
DILUTE AS 2% MAY CAUSE BURNS.
INHALATION...................MILD EXPOSURE:. INHALATION OF VAPOUR OR
MIST CAN CAUSE IRRITATION OF NOSE, THROAT
AND LUNGS.ONSET OF SYMPTOMS MAY BE DELAYED
FOR SEVERAL HOURS.SEVERE EXPOSURE:. CAN
CAUSE NOSE AND THROAT BURNS, LUNG
INFLAMMATION AND PULMONARY EDEMA (FLUID IN
THE LUNGS).ALSO RESULTS IN OTHER TOXIC
EFFECTS INCLUDING HYPOCALCEMIA (DEPLETION
OF CALCIUM IN THE BODY) WHICH IF NOT
PROMPTLY TREATED CAN RESULT IN DEATH.
INGESTION....................SWALLOWING MAY BE FATAL.CAUSES SEVERE
BURNS OF MOUTH, ESOPHAGUS AND STOMACH.EVEN
WITH SMALL AMOUNTS OR DILUTE SOLUTIONS,
PROFOUND AND POSSIBLY FATAL HYPOCALCEMIA
(DEPLETION OF CALCIUM IN BODY) AND
SYSTEMIC TOXICITY IS LIKELY TO OCCUR
UNLESS MEDICAL TREATMENT IS PROMPTLY
INITIATED.
ADDITIONAL INFORMATION.............THE EFFECTS OF CONTACT WITH DILUTE
SOLUTIONS OF HYDROFLUORIC ACID OR ITS
VAPOURS MAY BE DELAYED. THE POTENTIAL
DELAY IN CLINICAL SIGNS OR SYMPTOMS FOR
DILUTE SOLUTIONS: 20-50% (HF
CONCENTRATION) - 1-8 HOURS (DELAY IN
SYMPTOMS); 0-20% (HF CONCENTRATION) - UP
TO 24 HOURS (DELAY IN SYMPTOMS). CAN ALSO
CAUSE BONE AND JOINT CHANGES IN HUMANS.
EFFECTS OF ACUTE EXPOSURE..........SEE ABOVE.
EFFECTS OF CHRONIC EXPOSURE........CAN CAUSE FLUORIDE POISONING. SEE ABOVE.
------------------------------------------------------------------------------
SECTION 04: FIRST AID MEASURES
------------------------------------------------------------------------------
...................................
INSTRUCTIONS:......................IN CASE OF SKIN CONTACT.REMOVE THE VICTIM
FROM THE CONTAMINATED AREA AND IMMEDIATELY
WASH THE BURNED AREA WITH PLENTY OF WATER
FOR A MINIMUM OF 15 MINUTES OR UNTIL
MEDICAL TREATMENT IS AVAILABLE.REMOVE ALL
CONTAMINATED CLOTHING WHILE WASHING
CONTINUOUSLY.AFTER THOROUGH WASHING FOR AT
LEAST 5 MINUTES, THE BURNED AREA SHOULD BE
IMMERSED IN A SOLUTION OF 0.13% ICED
AQUEOUS "ZEPHIRAN CHLORIDE" UNTIL PAIN IS
RELEIVED.AS AN ALTERNATIVE FIRST AID
TREATMENT, 2.5% CALCIUM GLUCONATE GEL MAY
BE CONTINUOUSLY MASSAGED INTO THE BURN
AREA UNTIL THE PAIN IS RELEIVED.FOR LARGE
BURNS OR BURNS TREATED WITH CALCIUM
GLUCONATE GEL (IN WHICH PAIN IS PRESENT
FOR LONGER THAN 30 MINUTES), A PHYSICIAN
SHOULD INJECT 5% AQUEOUS CALCIUM GLUCONATE
BENEATH, AROUND AND IN THE BURNED AREA.EYE
CONTACT:. FLUSH THE EYES WITH RUNNING
WATER FOR 15 MINUTES. HOLD THE EYELIDS
APART DURING THE RINSING TO ENSURE
FLUSHING OF THE ENTIRE SURFACE OF THE EYE
AND LIDS WITH WATER.SEEK MEDICAL ATTENTION
URGENTLY, PREFERABLY FROM AN
OPHTHALMOLOGIST.IF A PHYSICIAN IS NOT
IMMEDATELY AVAILABLE, APPLY ONE OR TWO
DROPS OF 0.5% "PONTOCAINE HYDROCHLORIDE
SOLUTION" FOLLOWED BY A SECOND IRRIGATION
FOR 15 MINUTES. DO NOT USE THE SOLUTION
DESCRIBED FOR SKIN TREATMENT. USE NO OILS
OR GREASES UNLESS INSTRUCTED TO DO SO BY A
PHYSICIAN. IRRIGATE WITH 1% CALCIUM
GLUCONATE IN NORMAL SALINE FOR 1 TO 2
HOURS TO PREVENT OR LESSEN CORNEAL
DAMAGE.IN CASE OF INHALATION, REMOVE TO
FRESH AIR.KEEP THE VICTIM LYING DOWN,
QUIET AND WARM.GET IMMEDIATE MEDICAL
ATTENTION.IF BREATHING HAS STOPPED, START
ARTIFICIAL RESPIRATION AT ONCE.OXYGEN MAY
BE GIVEN BY QUALIFIED PERSONNEL. DO NOT
GIVE STIMULANTS UNLESS INSTRUCTED TO DO SO
BY A PHYSICIAN. VICTIM SHOULD BE EXAMINED
BY A PHYSICIAN AND HELD UNDER OBSERVATION
FOR AT LEAST 24 HOURS.IN CASE OF
INGESTION:. DRINK LARGE AMOUNT OF WATER TO
DILUTE.DO NOT INDUCE VOMITING.SEVERAL
GLASSES OF MILK OR SEVERAL OUNCES OF MILK
OF MAGNESIA MAY BE GIVEN FOR THEIR
SOOTHING EFFECT.TAKE VICTIM TO A DOCTOR.
NOTES TO PHYSICIAN:................FOR BURNS OF LARGE AREAS, (GREATER THAN 25
SQUARE INCHES), FOR INGESTION AND FOR
SIGNIFICANT INHALATION EXPOSURE, SEVERE
SYSTEMIC EFFECTS MAY OCCUR. MONITOR AND
CORRECT FOR HYPOCALCEMIA, CARDIAC
ARRHYTHMIAS, HYPOMAGNESEMIA AND
HYPERKALEMIA. IN SOME CASES RENAL DIALYSIS
MAY BE INDICATED. FOR CERTAIN BURNS,
ESPECIALLY OF THE DIGITS, USE OF
INTRA-ARTERIAL CALCIUM GLUCONATE MAY BE
INDICATED. TREAT AS CHEMICAL PNEUMONIA.
MONITOR FOR HYPOCALCEMIA. 2.5% CALCIUM
GLUCONATE IN NORMAL SALINE BY NEBULIZER OR
BY IPPB WITH 100% OXYGEN MAY DECREASE
PULMONARY DAMAGE. BRONCHODILATORS MAY ALSO
BE ADMINISTERED.
