Starters, or oil heater until you are sure ALL POWER IS OFF and no residual voltage can leak from capacitors or solid-state components. Refrigerant in contact with an open flame produces toxic gases.ĭO NOT USE eyebolts or eyebolt holes to rig machine sections or the entireĭO NOT work on high-voltage equipment unless you are a qualified electrician.ĭO NOT WORK ON electrical components, including control panels, switches, Traces of vapor should be displaced with dry air or nitrogen and the work area should be well ventilated. (liquid and vapor) has been removed from chiller. Use only refrigerant or dry nitrogen.īE SURE that all pressure relief devices are properly installed and functioningĭO NOT WELD OR FLAMECUT any refrigerant line or vessel until all refrigerant NEVER EXCEED specified test pressures, VERIFY the allowable test pressure byĬhecking the instruction literature and the design pressures on the equipmentĭO NOT USE air for leak testing. Oxygen gas reacts violently with oil, grease, and other common substances. Decomposition products are hazardous.ĭO NOT USE OXYGEN to purge lines or to pressurize a machine for any purpose. Vapor is heavier than air and reduces the amount of oxygen available for breathing. Harmful and may cause heart irregularities, unconsciousness, or death. Inhalation of high concentrations of vapor is PROVIDE adequate ventilation in accordance with ASHRAE 15, especially forĮnclosed and low overhead spaces. Refrigerant in an enclosed space can displace oxygen and cause asphyxiation.
