Potential Health Effects

Eye Contact: May cause severe eye irritation. May cause corneal injury. Vapor of amines may cause 

swelling of the cornea resulting in visual disturbances such as blurred or hazy vision. Bright lights may 

appear to be surrounded by halos. Effects may be delayed and typically disappear spontaneously. 

Skin Contact: Prolonged contact may cause severe skin irritation with local redness and discomfort. 

Skin Absorption: Prolonged skin contact is unlikely to result in absorption of harmful amounts. 

Repeated skin contact may result in absorption of harmful amounts. Massive contact with damaged 

skin or of material sufficiently hot to burn skin may result in absorption of potentially lethal amounts. 

Inhalation: Prolonged excessive exposure may cause adverse effects. In confined or poorly 

ventilated areas, vapor can easily accumulate and can cause unconsciousness and death due to 

displacement of oxygen. May cause respiratory irritation and central nervous system depression. 

Symptoms may include headache, dizziness and drowsiness, progressing to incoordination and 

unconsciousness. Symptoms of excessive exposure may be anesthetic or narcotic effects; dizziness 

and drowsiness may be observed. Excessive exposure may increase sensitivity to epinephrine and 

increase myocardial irritability (irregular heartbeats). Excessive exposure may cause severe irritation 

to upper respiratory tract (nose and throat) and lungs. 

Ingestion: Oral toxicity is expected to be moderate in humans due to diethylene glycol even though 

tests with animals show a lower degree of toxicity. Small amounts swallowed incidentally as a result of 

normal handling operations are not likely to cause injury; however, swallowing larger amounts may 

cause serious injury, even death. May cause nausea and vomiting. May cause abdominal discomfort 

or diarrhea. Excessive exposure may cause central nervous system effects, cardiopulmonary effects 

(metabolic acidosis), and kidney failure. 

Effects of Repeated Exposure: Contains a component which is reported to be a weak 

organophosphate-type cholinesterase inhibitor. Excessive exposure may produce organophosphate 

type cholinesterase inhibition. Signs and symptoms of excessive exposure may be headache, 

dizziness, incoordination, muscle twitching, tremors, nausea, abdominal cramps, diarrhea, sweating, 

pinpoint pupils, blurred vision, salivation, tearing, tightness in chest, excessive urination, convulsions. 

Contains component(s) which have been reported to cause effects on the following organs in animals: 

Liver. Heart. Respiratory tract. Central nervous system. Bladder. Contains component(s) which 

have been reported to cause effects on the following organs in humans: Kidney. Gastrointestinal 

tract. 

Birth Defects/Developmental Effects: Contains component(s) which did not cause birth defects in 

animals; other fetal effects occurred only at doses toxic to the mother. Diethylene glycol has caused 

toxicity to the fetus and some birth defects at maternally toxic, high doses in animals. Other animal 

studies have not reproduced birth defects even at much higher doses that caused severe maternal 

toxicity. 

Reproductive Effects: In animal studies on component(s), effects on reproduction were seen only at 

doses that produced significant toxicity to the parent animals. Diethylene glycol did not interfere with 

reproduction in animal studies except at very high doses.

4. First-aid measures 

Eye Contact: Immediately flush eyes with water; remove contact lenses, if present, after the first 5 

minutes, then continue flushing eyes for at least 15 minutes. Obtain medical attention without delay, 

preferably from an ophthalmologist. Eye wash fountain should be located in immediate work area. 

Skin Contact: Immediately flush skin with water while removing contaminated clothing and shoes. Get 

medical attention if symptoms occur. Wash clothing before reuse. Destroy contaminated leather items 

such as shoes, belts, and watchbands. Safety shower should be located in immediate work area. 

Inhalation: Move person to fresh air. If not breathing, give artificial respiration; if by mouth to mouth 

use rescuer protection (pocket mask, etc). If breathing is difficult, oxygen should be administered by 

qualified personnel. Call a physician or transport to a medical facility. 

Ingestion: Do not induce vomiting. Seek medical attention immediately. If person is fully conscious 

give 1 cup or 8 ounces (240 ml) of water. If medical advice is delayed and if an adult has swallowed 

several ounces of chemical, then give 3-4 ounces (1/3-1/2 Cup) (90-120 ml) of hard liquor such as 80 

proof whiskey. For children, give proportionally less liquor at a dose of 0.3 ounce (1 1/2 tsp.) (8 ml) 

liquor for each 10 pounds of body weight, or 2 ml per kg body weight [e.g., 1.2 ounce (2 1/3 tbsp.) for a 

40 pound child or 36 ml for an 18 kg child]. 

Notes to Physician: Due to structural analogy and clinical data, this material may have a mechanism 

of intoxication similar to ethylene glycol. On that basis, treatment similar to ethylene glycol intoxication 

may be of benefit. In cases where several ounces (60 - 100 ml) have been ingested, consider the use 

of ethanol and hemodialysis in the treatment. Consult standard literature for details of treatment. If 

ethanol is used, a therapeutically effective blood concentration in the range of 100 - 150 mg/dl may be 

achieved by a rapid loading dose followed by a continuous intravenous infusion. Consult standard 

literature for details of treatment. 4-Methyl pyrazole (Antizol®) is an effective blocker of alcohol 

dehydrogenase and should be used in the treatment of ethylene glycol (EG), di- or triethylene glycol 

(DEG, TEG), ethylene glycol butyl ether (EGBE), or methanol intoxication if available. Fomepizole 

protocol (Brent, J. et al., New England Journal of Medicine, Feb. 8, 2001, 344:6, p. 424-9): loading 

dose 15 mg/kg intravenously, follow by bolus dose of 10 mg/kg every 12 hours; after 48 hours, 

increase bolus dose to 15 mg/kg every 12 hours. Continue fomepizole until serum methanol, EG, 

DEG, TEG or EGBE are undetectable. The signs and symptoms of poisoning include anion gap 

metabolic acidosis, CNS depression, renal tubular injury, and possible late stage cranial nerve 

involvement. Respiratory symptoms, including pulmonary edema, may be delayed. Persons receiving 

significant exposure should be observed 24-48 hours for signs of respiratory distress. In severe 

poisoning, respiratory support with mechanical ventilation and positive end expiratory pressure may be 

required. Maintain adequate ventilation and oxygenation of the patient. If lavage is performed, 

suggest endotracheal and/or esophageal control. Danger from lung aspiration must be weighed 

against toxicity when considering emptying the stomach. May cause asthma-like (reactive airways) 

symptoms. Bronchodilators, expectorants, antitussives and corticosteroids may be of help. This 

material is a cholinesterase inhibitor. Treat symptomatically. In case of severe acute poisoning, use 

antidote immediately after establishing an open airway and respiration. Atropine, only by injection, is 

the preferable antidote. Oximes, such as 2-PAM/protopam, may be therapeutic if used early; however, 

use only in conjunction with atropine. Attempt seizure control with diazepam 5-10 mg (adults) 

intravenous over 2-3 minutes. Repeat every 5-10 minutes as needed. Monitor for hypotension, 

respiratory depression, and need for intubation. Consider second agent if seizures persist after 30 mg. 

If seizures persist or recur administer phenobarbital 600-1200 mg (adults) intravenous diluted in 60 ml 

0.9% saline given at 25-50 mg/minute. Evaluate for hypoxia, dysrhythmia, electrolyte disturbance, 

hypoglycemia (treat adults with dextrose 100 mg intravenous). If exposed, plasma and red blood cell 

cholinesterase tests may indicate significance of exposure (baseline data are useful). If burn is 

present, treat as any thermal burn, after decontamination. Exposure may increase "myocardial 

irritability". Do not administer sympathomimetic drugs such as epinephrine unless absolutely 

necessary. Exposure to amine vapors may cause minor transient edema of the corneal epithelium 

(glaucopsia) with blurred vision, blue haze and halos around bright objects. Effects disappear in a few 

hours and temporarily reduce ability to drive vehicles. Treatment of exposure should be directed at the 

control of symptoms and the clinical condition of the patient. 

Medical Conditions Aggravated by Exposure: Excessive exposure may aggravate preexisting 

asthma and other respiratory disorders (e.g. emphysema, bronchitis, reactive airways dysfunction 

syndrome).

Emergency Personnel Protection: First Aid responders should pay attention to self-protection and 

use the recommended protective clothing (chemical resistant gloves, splash protection). If potential for 

exposure exists refer to Section 8 for specific personal protective equipment. 

5. Fire Fighting Measures 

Extinguishing Media: Water fog or fine spray. Dry chemical fire extinguishers. Carbon dioxide fire 

extinguishers. Foam. Do not use direct water stream. May spread fire. Alcohol resistant foams (ATC 

type) are preferred. General purpose synthetic foams (including AFFF) or protein foams may function, 

but will be less effective. 

Fire Fighting Procedures: Keep people away. Isolate fire and deny unnecessary entry. Use water 

spray to cool fire exposed containers and fire affected zone until fire is out and danger of reignition has 

passed. Fight fire from protected location or safe distance. Consider the use of unmanned hose 

holders or monitor nozzles. Immediately withdraw all personnel from the area in case of rising sound 

from venting safety device or discoloration of the container. Do not use direct water stream. May 

spread fire. Move container from fire area if this is possible without hazard. Burning liquids may be 

moved by flushing with water to protect personnel and minimize property damage. Contain fire water 

run-off if possible. Fire water run-off, if not contained, may cause environmental damage. Review the 

"Accidental Release Measures" and the "Ecological Information" sections of this (M)SDS. 

Special Protective Equipment for Firefighters: Wear positive-pressure self-contained breathing 

apparatus (SCBA) and protective fire fighting clothing (includes fire fighting helmet, coat, trousers, 

boots, and gloves). Avoid contact with this material during fire fighting operations. If contact is likely, 

change to full chemical resistant fire fighting clothing with self-contained breathing apparatus. If this is 

not available, wear full chemical resistant clothing with self-contained breathing apparatus and fight fire 

from a remote location. For protective equipment in post-fire or non-fire clean-up situations, refer to 

the relevant sections. 

Unusual Fire and Explosion Hazards: Container may rupture from gas generation in a fire situation. 

Blowing agent vaporizes quickly at room temperature. Violent steam generation or eruption may occur 

upon application of direct water stream to hot liquids. 

Hazardous Combustion Products: During a fire, smoke may contain the original material in addition 

to combustion products of varying composition which may be toxic and/or irritating. Combustion 

products may include and are not limited to: Carbon monoxide. Carbon dioxide. Hydrogen halides. 

6. Accidental Release Measures 

Steps to be Taken if Material is Released or Spilled: Contain spilled material if possible. Absorb 

with materials such as: Dirt. Sand. Sawdust. Collect in suitable and properly labeled containers. 

Wash the spill site with water. See Section 13, Disposal Considerations, for additional information. 

Personal Precautions: Isolate area. Keep unnecessary and unprotected personnel from entering the 

area. Spilled material may cause a slipping hazard. Keep upwind of spill. Ventilate area of leak or 

spill. Refer to Section 7, Handling, for additional precautionary measures. Use appropriate safety 

equipment. For additional information, refer to Section 8, Exposure Controls and Personal Protection. 

Environmental Precautions: Prevent from entering into soil, ditches, sewers, waterways and/or 

groundwater. See Section 12, Ecological Information. 

7. Handling and Storage 

Handling 

General Handling: Do not get in eyes. Avoid breathing vapor. Avoid contact with skin and clothing.

Exposure Limits

Component List Type Value |

1,1,1,3,3 - Pentafluoropropane AIHA WEEL TWA 1,644 mg/m3 300 ppm ||

Diethylene glycol AIHA WEEL TWA 10 mg/m3 |

N,N-Dimethylcyclohexylamine Dow IHG TWA 1 ppm SKIN 

A "skin" notation following the exposure guideline refers to the potential for dermal absorption of the 

material including mucous membranes and the eyes either by contact with vapors or by direct skin 

contact. 

It is intended to alert the reader that inhalation may not be the only route of exposure and that 

measures to minimize dermal exposures should be considered. 

Personal Protection

Eye/Face Protection: Use chemical goggles. If exposure causes eye discomfort, use a full-face 

respirator. Eye wash fountain should be located in immediate work area. 

Skin Protection: 

Hand protection: Use gloves chemically resistant to this material. Use gloves with insulation 

for thermal protection, when needed. Examples of preferred glove barrier materials include: 

Chlorinated polyethylene. Polyethylene. Ethyl vinyl alcohol laminate ("EVAL"). Polyvinyl 

alcohol ("PVA"). Styrene/butadiene rubber. Viton. Examples of acceptable glove barrier 

materials include: Butyl rubber. Natural rubber ("latex"). Polyvinyl chloride ("PVC" or "vinyl"). 

NOTICE: The selection of a specific glove for a particular application and duration of use in a 

workplace should also take into account all relevant workplace factors such as, but not limited 

to: Other chemicals which may be handled, physical requirements (cut/puncture protection, 

dexterity, thermal protection), potential body reactions to glove materials, as well as the 

instructions/specifications provided by the glove supplier. 

Respiratory Protection: Respiratory protection should be worn when there is a potential to exceed 

the exposure limit requirements or guidelines. If there are no applicable exposure limit requirements 

or guidelines, use an approved respirator. When respiratory protection is required, use an approved 

positive-pressure self-contained breathing apparatus or positive-pressure airline with auxiliary selfcontained air supply. For emergency conditions, use an approved positive-pressure self-contained 

breathing apparatus. In confined or poorly ventilated areas, use an approved self-contained breathing 

apparatus or positive pressure air line with auxiliary self-contained air supply. 

Ingestion: Avoid ingestion of even very small amounts; do not consume or store food or tobacco in 

the work area; wash hands and face before smoking or eating. 

Engineering Controls

Ventilation: Use engineering controls to maintain airborne level below exposure limit requirements or 

guidelines. If there are no applicable exposure limit requirements or guidelines, use only in enclosed 

systems or with local exhaust ventilation. Exhaust systems should be designed to move the air away 

from the source of vapor/aerosol generation and people working at this point. Lethal concentrations 

may exist in areas with poor ventilation.
