Hazards
Hazards
LOGIX panels are rated to operate on a voltage of 24 volts DC or less. The LOGIX panel is below the 50 volt limit allowing for Field Service Technicians to access, troubleshoot, diagnosis and replacement of LOGIX panel components. Employees should be aware that units could contain flammable and toxic gasses. Potential for the possible hazards of gas ignition or fire, hot surfaces & fluids, rotating equipment. Risk of possible concentration of H2S. Hazardous gases could be in the units pressure vessels, cooler, or associated piping and risk of inhalation of hazardous gas fumes.
Safety
Safety
If working on a LOGIX panel that has previously been in service in the field, or has been on a running unit when on the Test Loop with natural gas the listed Safety requirements must be met.
All Personal Protective Equipment (PPE) for normal Field Mechanical duties apply for this procedure.
Four Gas Monitor, which is outlined in the Flogistix EHSS Manual, PPE Section 8, Procedure 8.3
Insure Flogistix personnel have proper safety certification or site orientation if required by the Flogistix Customer.
Insure Flogistix personnel adhere to all Customers safety practices.
