3. Hazard Identification
Potential Health Effects:
FE-232 HCFC-123 Dupont
Inhalation:
Inhalation of high concentrations of vapor is harmful and may cause cardiac irregularities, unconsciousness, and even death. Intentional misuse and deliberate inhalation of this product may result in death without warning. Vapor reduces the availability of oxygen for breathing because it is heavier than air. This product causes mild eye irritation. Decomposition products are hazardous.
Effects on human health:
Contact with eyes may cause irritation with discomfort, tearing, or blurred vision.
Overexposure via inhalation of vapors may cause temporary depression of the nervous system accompanied by symptoms associated with anesthesia such as: dizziness, headache, confusion, loss of coordination, nausea, and loss of consciousness. With overexposure (>2%), there is a possibility of temporary alterations in the electrical activity of the heart with irregular pulse, palpitations or inadequate circulation. Individuals with pre-existing diseases of the nervous system or the cardiovascular system have an increased susceptibility to toxicity from overexposure to the product.

4. First Aid Measures
Inhalation
If high concentrations are inhaled, immediately move the person to an area with fresh air and keep calm. If the person is not breathing, give artificial respiration. If breathing is difficult, administer oxygen. Call a doctor.
Skin Contact
In case of contact, wash the affected area with plenty of water for 15 minutes. If irritation occurs, call a doctor.
Eye Contact
In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Call a physician.
Ingestion
Material poses an aspiration hazard. If swallowed, do not induce vomiting. Immediately drink two glasses of water. Never give anything by mouth.

Mouth to an unconscious person. Call a physician. If vomiting occurs naturally, tilt the person forward to reduce the risk of aspiration.
Note to Physicians:
THIS MATERIAL MAY MAKE THE HEART MORE SUSCEPTIBLE TO ARRHYTHMIAS.
Catecholamines such as adrenaline and other compounds with similar effects should be reserved for emergencies and used only under special precautions.

5. Fire Fighting Measures
Flammability Properties
Flash Point: Will not burn
Flammability Limits in Air % by Volume:
LEL: Not applicable per ASTM E681
UEL: Not applicable per ASTM E681
Autoignition: Not determined
Extinguishing Media
As appropriate to materials present in the area.
Fire Fighting Instructions
Use water spray to cool cylinders. Self-contained breathing apparatus (SCBA)
is required in case drums rupture and contents are released under fire conditions.
Liquid water residue should be contained and neutralized prior to release.

6. Accidental Release Measures
Ventilate the leak area.
Du Pont Emergency Exposure Limits (EEL) are established to facilitate the task of emergency evacuation of the site or plant and specify the concentrations that, for a short period of time, the human body can withstand without suffering permanent damage to health or interfering with the evacuation process. EELs are expressed in concentrations multiplied by time, maximum 60 minutes and a ceiling concentration.
These limits are used in conjunction with engineering controls and monitoring and as an aid in planning for leaks and random spills.
DuPont’s EEL for FE-232 HCFC-123 is 1000 ppm for up to 60 minutes with a one minute tolerance not to exceed a concentration of 2500 ppm.
Initial Containment
Spill. Prevent liquid from entering drains, waterways or low-lying areas. Ventilate area.
Cleanup
Coup spill with absorbent material and transfer to steel drums for recovery/disposal. Follow applicable Federal, State and Local regulations.

7. Handling and Storage
Handling (Personnel)
Avoid breathing high concentrations of vapors. Provide adequate ventilation for storage, handling and use, especially in enclosed or low-lying areas.
Avoid contact with skin and/or eyes for long periods of time. Do not allow product to come into contact with open flames or electrical heating elements as hazardous decomposition products may be formed.
Recommendations to minimize exposure
. Training of all personnel.
. Maintain closed system as much as possible
. Adequate ventilation in mixing or filling areas
. Continuous monitoring in process areas
. Periodic testing of emissions at worker level
. Communication of handling procedures with repackagers is required
FE-232 HCFC-123 should only be used as a portable extinguishing agent and never used as a total flooding agent where people may be present. The reason is that the concentration required for this product to function as a fire extinguisher is well above the LOAEL (the lowest concentration exposure test at which cardiac sensitization occurs in laboratory animals).
The use of FE-232 HCFC-123 for total flooding in places where humans may be present could put them at risk of serious injury or death.
FE-232 HCFC-123 IS FOR USE ONLY AS A PORTABLE FIRE EXTINGUISHING AGENT IN OUTDOORS, LARGE OPEN SPACES, ENCLOSURES WITH ADEQUATE FORCED AIR EXCHANGE, OR UNOCCUPIED ENCLOSURES.
FE-232 HCFC-123 has cardiac sensitizing effects at concentrations greater than 2 vol.% (LOAEL) by volume in air. The concentration required for extinguishment is 6.3 vol.% (“heptane cup burner value”). When the 30% safety factor is added to the design concentration, the resulting concentration is 8.2 vol.%. This is more than 4 times the concentration that can cause a cardiac event.
Storage
This product must be stored in clean, dry areas. Do not heat above 52°C (125°F)

8. Exposure Controls/Personal Protection
Engineering Controls
Use only with adequate ventilation. Keep container tightly closed.
Vapors are heavier than air and pose a risk of suffocation if trapped in confined or low-lying areas.
Personal Protective Equipment
Wear safety glasses or goggles appropriate for handling chemicals.
Use NIOSH-approved respiratory protection if exposure limits are in danger of being exceeded. If skin contact is possible, have impervious protection available: gloves, apron,pants and jacket.

11. Toxicological information
Animal data
FE-232 HCFC-123
Inhalation 4-hour LC50 : 32000 ppm in rats
ALD Oral : 9000 mg/kg in rats
Skin absorption LD50 : > 2000 mg/kg in rabbitsAnimal tests indicate that FE-232 HCFC-123 is not a skin irritant or skin sensitizer, but is a moderate eye irritant. Toxic effects in animals at single exposures to concentrations equal to or greater than 5000 ppm include; unconditional reflexes, effects on locomotor activity and coordination, suggesting anesthetic effects. Single inhalations caused central nervous system effects such as anesthesia and nonspecific effects associated with lethal symptoms. Cardiac sensitization in dogs occurred at concentrations equal to or greater than 20,000 ppm. Repeated exposures to 300 ppm resulted in decreased cholesterol, triglycerides, or glucose and increased urinary fluoride levels. Concentrations of 5,000 ppm or greater resulted in anesthetic effects, decreased lymphocyte counts, changes in organ weights (including increased liver weight), enzyme alterations, and decreased weight gain. Exposures of dogs, guinea pigs, or monkeys to 1,000 ppm or greater induced mild to moderate liver damage. FE-232 HCFC-123 was not shown to be neurotoxic in animals repeatedly exposed to inhalation of the product at concentrations up to 5,000 ppm. Long-term exposure caused decreased body weight, reduced cholesterol, triglycerides, and glucose, and increased urinary fluoride concentrations in rats. Inhalation of 300, 1000, or 5000 ppm for two years caused an increase in benign testicular tumors in male rats.
An increase in benign pancreatic and liver tumors was observed in rats exposed to 1000 or 5000 ppm. The tumors were considered late-onset and were judged not to be life-threatening. The biological significance of these tumors to humans is limited. Additionally, there is evidence that retinal atrophy was observed during this two-year study in both treated and controlled animals; the significance of this is not yet determined.
Animal data indicate that FE-232 HCFC-123 did not affect the reproductive cycle in rats. Animal data indicate that it does not specifically harm the unborn child.
FE-232 HCFC-123 does not cause genetic damage in bacterial cell cultures or in animals themselves, however, in one study genetic damage was caused in mammary cell cultures.
Inhalation of high vapor concentrations is harmful and can cause cardiac irregularities, unconsciousness and even death.
Overexposure via inhalation of vapors can cause temporary depression of the nervous system accompanied by symptoms associated with anesthesia such as: dizziness, headache, confusion, loss of coordination, nausea and loss of consciousness.
With overexposure (>2%), there is the possibility of temporary alterations in the electrical activity of the heart with irregular pulse, palpitations or inadequate circulation.
Toxic effects in animals from single exposures to concentrations equal to or greater than 5000 ppm include unconditional reflexes, effects on the activity of the heart, and locomotor function and coordination, suggesting anesthetic effects. Single inhalations caused central nervous system effects including anesthesia and nonspecific effects associated with lethal symptoms. Cardiac sensitization in dogs occurred at concentrations equal to or greater than 20,000 ppm
