HAZARDOUS MATERIALS SAFETY

Carbonic Systems, Inc. stores, handles, sells and transports the following materials:

COMPRESSED GASES - Helium, Nitrogen, Carbon Dioxide, 75% Nitrogen-25% Carbon Dioxide (compressed gases, n.o.s.) and Oxygen. DRYICE (solid Carbon Dioxide) and BULK REFRIGERATED LIQUID CARBON DIOXIDE.

Each of these hazardous materials are considered hazardous for one or more of the following reasons:

1. HIGH PRESSURE: Cylinder gases are stored in cylinders with pressures ranging from 400-2400 psi. The valve is the weakest part of the cylinder, which is why cylinder caps are required on all but the smaller cylinders. If a full cylinder were to fall over and the valve cracked, this cylinder could take off like a rocket and go through a brick wall and still not stop. This is why cylinders are to be secured when transporting and why all cylinders must be hydro-statically re-tested every 5-10 years (depending on the type of cylinder) to prevent cylinder ruptures. Examples of hazardous materials that have this potential hazard: Helium, Oxygen, Nitrogen, Compressed Gases, n.o.s., and Carbon Dioxide.

2. ASPHYXIANT: Most of the gases we handle will not support life and are, therefore, dangerous in small and large concentrations. All of our gases are odorless and colorless making detection next to impossible. At concentrations between 2% and 10% these gases can cause nausea, dizziness, headache, mental confusion, increased blood pressure and respiratory rate. Exposure to these gases can also cause asphyxiation, through displacement of oxygen. If the gas concentration reaches 10% or more, suffocation can occur within minutes. These gases must be handled in a well-ventilated area. Remove exposed victims(s) to fresh air as quickly as possible. Trained personnel should administer supplemental oxygen and/or cardio-pulmonary resuscitation, if necessary. Examples of hazardous materials that have this potential hazard: Nitrogen, Helium, Carbon Dioxide, Compressed Gases, n.o.s., Refrigerated Bulk Liquid Carbon Dioxide and Dry Ice.

3. COLD TEMPERATURES: Liquid, gaseous, and solid carbon dioxide (Dry Ice) are very cold (-70 degrees to -109 degrees Fahrenheit) and can cause frost bite, an injury resembling a burn. Wear protective clothing (gloves and long-sleeved shirt) when handling, delivering or trans-filling containers with these products. First aid of frostbite includes warming the affected area with warm water and then treating the area the same as a burn.

4. ACCELERATES COMBUSTION: Oxygen is non-flammable, but supports and vigorously accelerates combustion of flammables. Do not smoke, use sparks or flames within 25 feet of flammable or combustible materials, especially oil or grease. Keep cylinders away from heat sources. Never lubricate valves or cylinder caps. Avoid exposure to salt or other corrosive chemicals. Oxygen is not a substitute for air. Do not use for cleaning, dusting or powering pneumatic tools.
