The Safety Knowledge in operation
Before the start of any testing it should be confirmed that all power supplies to the system have
been isolated or that they are in a known condition. The Commissioning engineer is
responsible for the safety of those personnel working of the system Check for the presence of
harmful electrical or mechanical potential energy before starting work.
1.3.2
Project lockout / Tagout(LOTO) procedures must be adhere to all test area.
1.3.3
Fire is strictly prohibited on site, no smoking there must be a warning mark in hazardous area.
1.3.4
Strictly comply with the safety and environmental protection regulations of local government.
1.3.5
In order to ensure the reliable operation of every part of the system, strictly obey the
corresponding procedures.
1.3.6
Have a regular maintenance for the long-time standby equipment
1.3.7
Obey the relevant safety regulations of the power plant during commissioning all along. Ensure
the successful commissioning work.
1.3.8
All personnel directly involved with the commissioning that will attend a kickoff safety meeting to
review for the dangers. Ensure that all personnel understand the process and the operation.
Page 5 of 28
Rev. A
Any personnel involved in the commissioning have the authority to terminate the operation at
any time, if a serious problem or safety issue develops.
