TLV Basis is fluorosis and methemoglobinemia. Dogs and rats exposed to 24 ppm for 6 months showed effects likely resulting from methemoglobinemia. No evidence of lung damage in dogs or rats exposed to 24 ppm; In subchronic studies of rats, dyspnea, cyanosis, methemoglobinemia, fluorosis, lung consolidation, and liver injury were observed. [ACGIH] Listed in the table Examples of Industrial Chemicals for Which Methemoglobin Formation is NOT the Principal Cause of Toxicity; [ACGIH] Possible frostbite from contact with liquid; [NIOSH] May cause respiratory tract irritation and pulmonary edema; Can induce methemoglobinemia; May cause fluorosis; [ICSC] See FLUORIDES.

Excerpt from ERG Guide 124 [Gases - Toxic and/or Corrosive - Oxidizing]:
In case of fire in the surroundings, use appropriate extinguishing media. In case of fire: keep cylinder cool by spraying with water.
Fresh air, rest. Half-upright position. Refer for medical attention.
ON FROSTBITE: rinse with plenty of water, do NOT remove clothes. Refer for medical attention .
First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.
· CALL 911. Then call emergency response telephone number on shipping paper. If shipping paper not available or no answer, refer to appropriate telephone number listed on the inside back cover.
· Do not touch or walk through spilled material.
Excerpt from NIOSH Pocket Guide for Perchloryl fluoride:
General First Aid:
(General first aid procedures)
· Wear positive pressure self-contained breathing apparatus (SCBA).
TIH (Toxic Inhalation Hazard) - Term used to describe gases and volatile liquids that are toxic when inhaled. Some are TIH materials themselves, e.g., chlorine, and some release TIH gases when spilled in water, e.g., chlorosilanes. [ERG 2016].
USUALLY STORED IN CYLINDERS AS LIQUID UNDER PRESSURE.
HANDLE WITH CARE. DO NOT BRING IN DIRECT CONTACT WITH REDUCING AGENTS, ALCOHOLS, ETC.
IN GENERAL, MATERIALS WHICH ARE TOXIC AS STORED OR WHICH CAN DECOMP INTO TOXIC COMPONENTS...SHOULD BE STORED IN A COOL, WELL-VENTILATED PLACE, OUT OF DIRECT RAYS OF THE SUN, AWAY FROM AREAS OF HIGH FIRE HAZARD, & SHOULD BE PERIODICALLY INSPECTED... INCOMPATIBLE MATERIALS SHOULD BE ISOLATED FROM EACH OTHER.
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
AVOID INHALATION, INGESTION & SKIN CONTACT. TAKE SPECIAL MEASURES IN CASES OF LEAK. /FROM TABLE/
SRP: Local exhaust ventilation should be applied wherever there is an incidence of point source emissions or dispersion of regulated contaminants in the work area. Ventilation control of the contaminant as close to its point of generation is both the most economical and safest method to minimize personnel exposure to airborne contaminants.
SRP: The scientific literature for the use of contact lenses in industry is conflicting. The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may be individual substances whose irritating or corrosive properties are such that the wearing of contact lenses would be harmful to the eye. In those specific cases, contact lenses should not be worn. In any event, the usual eye protection equipment should be worn even when contact lenses are in place.

MUCOUS MEMBRANE, SKIN, LUNG, CORNEA IRRITATION & CYANOSIS. /FROM TABLE/
...MEN EXPOSED TO UNKNOWN CONCN OF CMPD /PERCHLORYL FLUORIDE/ FOR BRIEF PERIODS REPORTED SYMPTOMS OF UPPER RESP IRRITATION.
CAUSES METHEMOGLOBINEMIA...
Perchloryl fluoride is a strong irritant of the eyes, mucous membranes, and lungs. In high concn it can produce pulmonary edema as well as methemoglobinemia. Exposure to toxic concn can produce weakness, syncope, and headache as well as severe respiratory tract irritation and pulmonary edema. Skin contact from the liquid form can produce burns.
Clinical symptomatology includes dizziness, headache, cyanosis, and syncope.
DOGS, RATS & MICE EXPOSED TO VAPOR DEVELOPED METHEMOGLOBINEMIA. DOGS EXPOSED... @ 220 TO 450 PPM FOR 4 HR & @ 620 PPM FOR 2.5 HR WERE CYANOTIC & HYPERPNEIC... IN DOGS, DYING FROM EXPOSURE, THERE WERE...PIGMENT DEPOSITION IN LIVER, SPLEEN & BONE MARROW; AREAS OF ALVEOLAR HEMORRHAGE, OF ALVEOLAR COLLAPSE & EMPHYSEMA.
IN REPEATED INHALATION EXPOSURES TO PERCHLORYL FLUORIDE @ 185 PPM FOR 6 HR/DAY, 5 DAYS/WK FOR 7 WK, 18 OF 20 RATS, 20 OF 39 MICE & 10 OF 10 GUINEA PIGS DIED...SIGNS OF TOXICITY & PATHOLOGICAL CHANGES WERE...DYSPNEA; CYANOSIS & METHEMOGLOBINEMIA; FLUOROSIS (PIGMENT ALTERATION IN INCISOR TEETH); PATCHY AREAS OF CONSOLIDATION IN RAT LUNG; SPLENOMEGALY; HEMOSIDEROSIS OF THE SPLEEN, LIVER AND KIDNEY; AND ALVEOLAR EDEMA FOLLOWING THE FIRST EXPOSURE WHICH DEVELOPED INTO BRONCHOPNEUMONIA.
ON SIMILAR EXPOSURES AT 104 PPM FOR 6 WKS, ALL 10 GUINEA PIGS AND 1 OF 20 RATS DIED. SIMILAR SIGNS AND ANATOMIC CHANGES WERE OBSERVED. CIRCULATING /BLOOD/ FLUORIDE CONCENTRATIONS INCREASED FROM 20- TO 30-FOLD, URINARY FLUORIDE LEVELS FROM 5- TO 8-FOLD, & RAT FEMUR FLUORIDE CONCENTRATIONS INCREASED 10-FOLD.
After inhaling perchloryl fluoride for 6 mo @ 24 ppm, 14 of 30 exposed and 1 of 30 control guinea pigs died, but these deaths in exposed animals were attributed to infection by bordetella bronchiseptica; there were no deaths in rats and dogs. Bone fluoride concentrations were increased to four times the control in guinea pigs and almost three times the control value in rats. Dogs had about 50% increase in bone fluoride. All species had congested spleens containing iron-bearing pigments. In guinea pigs, there was an increase in normoblasts and a slight but nonsignificant decrease in total hemoglobin. In dogs, a two fold increase in the indirect fraction of serum bilirubin was demonstrated. There was no evidence of irritation observed in these animals that were exposed to 24 ppm.
