May cause eye irritation. Skin
Exposure may cause irritation characterized by redness, dryness & inflammation. Inhaled
Inhalation of a mist of this material may cause respiratory tract irritation. 2.2 Health Effects - Chronic
No data available.
2.3 First Aid
Swallowed
If vomiting occurs, keep head lower than hips to help prevent aspiration. If person is unconscious, turn head to side. Get medical attention immediately.
Eye
Wash eyes immediately with large amounts of water or normal saline, occasionally lifting upper and lower lids, until no evidence of chemical remains. Get medical attention immediately.
Skin
Remove contaminated clothing, jewellery, and shoes immediately. Wash with soap or mild detergent and large amounts of water until no evidence of chemical remains (at least 15 - 20 minutes). Get medical attention, if needed.
Inhaled
Remove from exposure immediately. Use a bag valve mask or similar device to perform artificial respiration (rescue breathing) if needed. Get medical attention.
First Aid Facilities
Ensure an eye bath and safety shower are available and ready for use.
2.5 Advice to Doctor
For ingestion, consider gastric lavage. Consider oxygen.
2.6 Toxicity Data

3. PRECAUTIONS FOR USE
3.1 Exposure Standards
No occupational exposure limits established.
3.2 Engineering Controls
Ensure adequate ventilation to maintain exposure levels at a minimum.
3.3 Personal Protection
Eye protection - wear appropriate chemical resistant safety goggles. Skin protection - wear appropraite chemical resistant clothing and chemical resistant gloves. Respiratory protection - under conditions of frequent use or heavy exposure, respiratory protection may be needed. Respiratory protection is ranked in order from minimum to maximum. Consider warning properties before use. Any chemical cartridge respirator with organic vapour cartridges. Any chemical cartridge respirator with a full facepiece and organic vapour cartridges. Any air-purifying respirator with a full facepiece and an organic vapour canister. For unknown concentrations or immediately dangerous to life or health - any supplied air respirator will full facepiece and operated in a pressure-demand or other positive pressure mode in combination with a separate escape supply. Any self-contained breathing apparatus with a full facepiece.
3.4 Flammability
Material is non-flammable but combustible. On heating it emits combustible vapours/fumes which form explosive mixtures with air. SAFE HANDLING INFORMATION
4.1 Storage / Transport
Store in tightly clsoed containers in a well ventilated area. Keep separated from incompatible materials such as acids, bases, oxidising materials. Avoid contact with heat, flames, sparks and other sources of ignition. Containers may rupture or explode if exposed to heat.
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 TRIETHYLENE GLYCOL Hazard

4.3 Spills and Disposal
Spills
Wear full protective gear. Avoid heat, flames, sparks and other sources of ignition. Remove sources of ignition. Stop leak if possible without personal risk. Reduce vapours with water spray.
Small spills - absorb with sand or other non-combustible material. Collect spilled material in appropriate container for disposal. Large spills - dike for later disposal. Keep unnecessary people away, isolate hazard area and deny entry. Stay upwind and keep out of low areas.
Disposal
Dispose of waste material in accordance with all Local, State & Federal regulations.
4.4 FIRE AND EXPLOSION HAZARD Fire / Explosion
Reacts violently with oxidising agents & strong acids. Hazardous decomposition products include carbon monoxide and carbon dioxide. Hazardous polymerisation will not occur.
Extinguishing Media
Use alcohol resistant foam, carbon dioxide, regular dry chemical, water, or alcohol resistant foam. For large fires - use alcohol resistant foam or flood with fine water spray. Move container from fire area if it can be done without risk. Cool containers with water spray until well after the fire is out. Stay away from the ends of tanks. For fire in cargo or storage area: cool containers with water form unmanned hose holder or monitor nozzles until well after fire is out. If this is impossible then take the following precautions: keep unnecessary people away, isolate hazard area and deny entry. Let the fire burn. Withdraw immediately in case of rising sound from venting safety device or any discolouration of tanks due to fire. For tank, rail car or tank truck: Evacuation radius: 800 metres (1/2 mile). Do not attempt to extinguish fire unless flow of material can be stopped first. Fllod with fine water spray. Do not scatter spilled material witg high pressure water streams. Cool containers with water spray until well after the fire is out. Apply water from a protected location or form a safe distance. Stay upwind and keep out of low areas. 5 OTHER INFORMATION
