Safety
One of the desirable qualities of QC Eco-Green Heat Transfer Fluid is its ease of handling from a personal safety viewpoint. However, a few reasonable precautions are necessary.

Due to QC Eco-Green Heat Transfer Fluid’s high viscosity, slight heating is usually required to lower the viscosity for easy transfer. It’s important to note, however, that QC Eco-Green Heat Transfer Fluid may degrade to oxidation by-products. QC Eco-Green Heat Transfer Fluid by-products have different toxicological and physical properties from QC Eco-Green Heat Transfer Fluid itself. See the Material Safety Data Sheet for more information. To minimize quality degradation, QC Eco-Green Heat Transfer Fluid should be used and stored below 54°C (130°F). In the presence of powerful oxidizing agents such as sodium hypochlorite or hypochlorous acid, a violent reaction may occur. Review the following exposure hazards and first aid procedures to establish and maintain safe working conditions.

EYES
May cause slight, transient irritation. Upon eye contact, flush the eyes with plenty of water.
 

SKIN
 A single prolonged exposure to QC Eco-Green Heat Transfer Fluid is not likely to be absorbed in significant amounts through the skin and so is not likely to cause significant irritation. Upon contact, skin may feel warm due to the absorption of moisture from the skin. QC Eco-Green Heat Transfer Fluid can be removed by washing with water. QC Eco-Green Heat Transfer Fluid may be absorbed in potentially harmful amounts when applied in large quantities to severe burns (second or third degree) over large areas of the body as part of a cream or other topical application. Absorption under such circumstances can elevate serum osmolality and may result in osmotic shock.

 INHALATION
 No significant irritation. The ACGIH Threshold Limit Value is 10 mg/m3 as a nuisance mist. If irritation occurs as a result of inhalation, remove person to an area of fresh air.
 

BIODEGRADATION DATA
Biodegradation under aerobic static laboratory conditions is high (BOD20 or BOD28/ThOD greater than 40 percent). It is expected that biodegradation will be achievable in a secondary wastewater treatment plant. The inhibitory concentration of QC Eco-Green Heat Transfer Fluid (IC50) in OECD “Activated Sludge, Respiration Inhibition Test” (Guideline #209) is greater than 1,000 mg/L. The five-day biochemical oxygen demand (BOD5) is 0.54 p/p, the 10-day biochemical oxygen demand (BOD10) is 0.98 p/p, the 20-day biochemical oxygen demand (BOD20) is 1.0 p/p and the theoretical oxygen demand (ThOD) is calculated to be 1.22 p/p.
