SECTION 6 - HEALTH HAZARD ASSESSMENT
______________________________________________________________________________________________________________________________________
GENERAL: THIS DESCRIPTION OF TOXICOLOGICAL PROPERTIES IS BASED ON EXPERIMENTAL RESULTS AND EXPERIENCE
--------------------------------------------------------------------------------------------------------------------------------------------------------
INGESTION: THE ACUTE ORAL LD50 IN RATS IS 810 MG/KG (MALES) AND 600 MG/KG (FEMALES). THIS MATERIAL IS CLASSIFIED AS "SLIGHTLY TOXIC" BY INGESTION. IN HUMANS, IRRITATION OF THE MOUTH, PHARYNX, ESOPHAGUS AND STOMACH CAN DEVELOP FOLLOWING INGESTION OF THIS PRODUCT. THE DEGREE OF INJURY WILL DEPEND ON THE AMOUNT ABSORBED FROM THE GUT. SYMPTOMS FOLLOWING INGESTION OF DIQUAT CONCENTRATE MAY INITIALLY INCLUDE NAUSEA, VOMITING, ABDOMINAL PAIN AND SEVERE IRRITATION OF THE MOUTH, THROAT AND ESOPHAGUS. THESE CAN BE FOLLOWED BY KIDNEY FAILURE AND OTHER INTERNAL ORGAN INVOLVEMENT.
--------------------------------------------------------------------------------------------------------------------------------------------------------
EYE CONTACT: THIS MATERIAL MAY IRRITATE HUMAN EYES FOLLOWING CONTACT AND COULD CAUSE PROLONGED (WEEKS) IMPAIRMENT OF VISION. THE DEGREE OF INJURY WILL DEPEND ON THE AMOUNT OF MATERIAL THAT GETS INTO THE EYE AND THE SPEED AND THOROUGHNESS OF THE FIRST AID TREATMENT. SYMPTOMS MAY INCLUDE PAIN, TEARS, SWELLING, REDNESS AND BLURRED VISION.
--------------------------------------------------------------------------------------------------------------------------------------------------------
SKIN CONTACT: SHORT CONTACT PERIODS WITH HUMAN SKIN ARE NOT USUALLY ASSOCIATED WITH SKIN IRRITATION, REPEATED AND/OR PROLONGED CONTACT CAN RESULT IN SKIN IRRITATION AND SKIN SENSITIZATION (ALLERGIC CONTACT DERMATITIS)/
--------------------------------------------------------------------------------------------------------------------------------------------------------
SKIN ABSORPTION: THE DERMAL LD50 IN RABBITS IS 260 MG/KG (MALES) AND 315 MG/KG (FEMALES). THIS MATERIAL IS MODERATELY TOXIC BY ABSORPTION. THE DEGREE OF INJURY WILL DEPEND ON THE AMOUNT ABSORBED. BECAUSE DIQUAT IS AN IONIZED COMPOUND, IT HAS A SLOW RATE OF ABSORPTION THROUGH INTACT SKIN. PROLONGED OR REPEATED CONTACT MAY RESULT IN SKIN DAMAGE, THUS ALLOWING MORE OF THE CHEMICAL TO BE ABSORBED. THIS COULD RESULT IN SYSTEMATIC POISONING AS EVIDENCED BY INJURY TO INTERNAL ORGANS, PRIMARILY THE KIDNEYS. THE NO-OBSERVED-EFFECT LEVEL (NOEL) FOR DERMAL TOXICITY OF DIQUAT TECHNICAL WAS FOUND TO BE 5MG/KG/DAY IN A 21-DAY STUDY IN RATS.

-------------------------------------------------------------------------------------------------------------------------------------------------INHALATION: THE 4-HOUR INHALATION LC50 IN RATS WAS 121 MG/M3 (MALES) AND 132 MG/M3 (FEMALES). THIS SUBSTANCE IS MODERATELY TOXIC TO INTERNAL ORGANS IF INHALED. THE DEGREE OF INJURY WILL DEPEND ON THE AIRBORNE CONCENTRATION AND DURATION OF EXPOSURE. DIQUAT IS A WATER-SOLUBLE SALT WHICH HAS NO MEASURABLE VAPOR PRESSURE. THEREFORE, THERE IS NO INHALATION HAZARD FROM DIQUAT VAPOR, IF THE CONCENTRATE IS SPILLED AND ALLOWED TO STAND, IT CAN DRY TO A HIGHLY IRRITATING DUST. SYMPTOMS OF INHALATION OVEREXPOSURE MAY INCLUDE HEADACHE, NOSEBLEED, SORE THROAT AND COUGHING.
--------------------------------------------------------------------------------------------------------------------------------------------------------
OTHER EFFECTS OF OVEREXPOSURE: NO OTHER ADVERSE CLINICAL EFFECTS HAVE BEEN ASSOCIATED WITH EXPOSURES.
--------------------------------------------------------------------------------------------------------------------------------------------------------
FIRST AID PROCEDURES:
GENERAL: IF A KNOWN EXPOSURE OCCURS OR IS SUSPECTED, IMMEDIATELY START THE RECOMMENDED PROCEDURES BELOW. IF FURTHER TREATMENT IS REQUIRED, CONTACT A POISON CENTER, A PHYSICIAN OR THE NEAREST HOSPITAL, INFORM THE PERSON CONTACTED OF THE TYPE AND EXTENT OF EXPOSURE, DESCRIBE THE VICTIM'S SYMPTOMS AND FOLLOW THE ADVICE GIVEN.
SKIN: WASH MATERIAL OFF OF THE SKIN WITH PLENTY OF SOAP AND WATER. IF REDNESS OCCURS OR DIQUAT CONTACTS A SKIN CUT OR AREA OF ABRASION, GET MEDICAL ATTENTION. WASH CONTAMINATED CLOTHING AND DECONTAMINATE FOOTWEAR BEFORE REUSE.
EYES: IMMEDIATELY FLUSH WITH PLENTY OF WATER FOR AT LEAST 15 MINUTES. IF REDNESS, ITCHING OR A BURNING SENSATION DEVELOP, HAVE EYES EXAMINED AND TREATED BY MEDICAL PERSONNEL.
INGESTION: GIVE 1 OR 2 GLASSES OF WATER TO DRINK AND REFER PERSON TO MEDICAL PERSONNEL (NEVER GIVE ANYTHING BY MOUTH TO AN UNCONSCIOUS PERSON)
INHALATION: REMOVE PERSON TO FRESH AIR, IF NOT BREATHING, GIVE ARTIFICIAL RESPIRATION, PREFERABLY MOUTH-TO MOUTH CONSULT MEDICAL PERSONNEL.
NOTE TO PHYSICIAN: CALL 1 800-FASTMED (327-8633) TO OBTAIN MEDICAL AND TOXICOLOGY INFORMATION. TO BE EFFECTIVE, TREATMENT FOR DIQUAT POISONING MUST BEGIN IMMEDIATELY. TREATMENT CONSISTS OF BINDING DIQUAT IN THE GUT WITH SUSPENSIONS OF ACTIVATED CHARCOAL ON BENTONITE CLAY, ADMINISTRATION OF CATHARTICS TO ENHANCE ELIMINATION, AND REMOVAL OF DIQUAT FROM THE BLOOD BY CHARCOAL HEMOPERFUSION OR CONTINUOUS DIALYSIS.
