2. HEALTH HAZARD INFORMATION
2.1 Health Effects - Acute Swallowed
Moderately toxic to human by ingestion. It may cause gastrointestinal irritation with nausea, headaches, dizziness and vomiting. Eye
May cause irritation to eyes. Skin
Prolonged or repeated exposure is not likely to cause significant skin irritation. A single prolonged exposure is not likely to result in the material being absorbed through skin in harmful amounts. Repeated skin exposure 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. Inhaled
At room temperature, the substance has such a low vapour pressure, inhalation of the vapour is unlikely. High vapour concentration caused by heating the substance in a confined and poorly ventilated area may cause coughing, chest pains, nausea and vomiting. High concentration exposure may cause central nervous system depression and progress to stupor and finally coma. 2.2 Health Effects - Chronic
Repeated excessive exposures may cause severe kidney and also liver and gastrointestinal effects. Signs and symptoms of excessive exposure may be central nervous system effects, nausea and/or vomiting and anesthetic or narcotic effects. Observations in animals include formation of bladder stones after repeated oral doses of diethylene glycol. Reports of kidney failure and death in burn patients suggest that diethylene glycol may have been a factor. The use of topical applications containing this material may not be appropriate in severely burned patients or individuals with impaired renal function.
2.3 First Aid
Swallowed
If swallowed and the person is fully conscious, give two glasses of water to drink. Induce vomiting. Seek medical attention.
Eye
Immediately flush eye with water for at least 15 minutes. If irritation develops consult a physician.
Skin
Remove any contaminated clothing and/or shoes. Wash affected skin area with soap and water for at least 15 minutes. If irritation develops, get medical attention. Wash contaminated clothing before reuse.
Inhaled
Move to fresh air, if breathing is difficult give oxygen. If symptoms develop induce vomiting. Seek medical attention.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
No specific antidote. Treat symptomatically based on judgement of doctor and individual reactions of patient. Repeated excessive exposure may aggravate preexisting liver and kidney disease.
2.6 Toxicity Data
Oral LD50 = 14.8 g/kg (rat) Dermal LD50 = 11.9 g/kg (rabbit) Inhalation TCL2 = 130 mg/m3/2hr (mouse).
3. PRECAUTIONS FOR USE
3.1 Exposure Standards
Diethylene glycol = AIHA WEEL - TWA = 55 ppm (vapour)
3.2 Engineering Controls
Ensure adequate ventilation to maintain exposure levels below standard.
3.3 Personal Protection
Respiratory protection - Use NIOSH/MSHA approved organic vapour cartridge for exposures less than 500 ppm. Above that level wear NIOSH/MSHA approved full facepiece self-contained breathing apparatus or a supplied air respirator. Eye protection - Wear chemical safety goggles. Skin protection - Where contact is likely, wear protective clothing and nitrile rubber gloves. Do not eat, drink or smoke in work area. Wash hands thoroughly after handling, especially before eating, drinking, smoking, chewing or using restroom facilities. Contaminated clothing and shoes should be thoroughly cleaned before reuse or properly disposed of.
3.4 Flammability
Material stable under normal conditions of storage and use. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Keep in tightly closed container. Store in cool, dry, well ventilated area. Protect against physical damage. Separate from oxidising agents, strong bases and strong acids. Use with adequate ventilation, avoid contact with eyes, skin and clothing. Avoid materials reactive with hydroxyl compounds.
4.2 Packaging / Labelling UN No. N/A Class C.2 Sub Risk None Allocated Hazchem Code N/A Pack Group 0 EPG No. N/A Shipping Name DIETHYLENE GLYCOL Hazard HARMFUL
Risk Phrases R19 May form explosive peroxides. R20/22 Harmful by inhalation and if swallowed.
Safety Phrases S24/25 Avoid contact with skin and eyes.
4.3 Spills and Disposal
Spills
Prevent product from entering waterways. Evacuate non essential personnel. Remove all sources of ignition. Ventilate area.
Stop the discharge if this can be done safely. If a substantial quantity is spilled, recover with pump or vacuum truck, otherwise, use an absorbent to remove the spill appropriate safety proceduresand protective equipment should be used. Notify appropriate authorities if necessary.
Disposal
Must be disposed of in accordance with Federal, state and local environment control regulations. Empty containers must be handled with care due to possible residue.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Product may decompose if heated to elevated temperatures, this product may burn and generate acrid smoke, irritating fumes, carbon dioxide, carbon monoxide. Hazardous polymerisation will not occur. Avoid contact with incompatible materials such as strong acids, strong bases, oxidising agents and materials reactive with hydroxyl compounds.
Extinguishing Media
Use dry chemical, water fog, alcohol foam or carbon dioxide. In the event of a fire, wear a NIOSH approved, positive pressure, self-contained breathing apparatus (SCBA) and full protective gear. Move container from fire area if it can be done without risk. Use water spray to keep fire-exposed containers cool. 5 OTHER INFORMATION
Other Information
Material is practically non-toxic to fish on an acute basis (LC50 > 100 mg/L) Material is highly toxic to aquatic invertebrates on an acute basis (0.1 mg/L < LC50 < 1.0 mg/L). Appreciable volatilisation from water to air is not expected in the environment. Log octanol/water partition coefficient (log Kow) is estimated using the Pomona-MedChem structural fragment method to be -1.305. Partition from water to n-octanol is low (log Kow < 0) Biodegradation under aerobic static laboratory conditions is high (BOD20/ThOD > 40%). Biodegradationis expected in a wastewater treatment plant. Inhibitory concentration (IH50) in OECD "Activated Sludge, Respiration Inhibition Test" is > 1000 mg/L.
