Proper equipment tagging

Periodically complete a site survey to ensure that the Process and Instrumentation Diagram (P&ID, also known as a flowsheet) accurately depicts plant equipment, valves and instruments as installed in the facility.

Effective Practices to Manage and Mitigate Hazards

Defer excavation to a future turnaround or outage

When the risk of excavation is considered unacceptable, consideration should be made to defer it until the plant is in a safer condition.

Identify all underground utilities and pipelines

All utilities and lines should be properly identified and appropriate parties notified before beginning any digging or clean-up work.

Prevent spoil falling back into excavation

Conducting initial field inspection

Ensure that the equipment that will be worked on is identified/tagged prior to issuing the SWP.
Confirm that the location is safe and does not require additional measures to control hazards.
- Safe access is available for the work crew
- Area is safe to move objects required for execution of the job
- Escape routes are clear

Equipment Filling and Mixing - Strategies & Effective Practices to Manage and Mitigate Hazards

Hazard Identification

Identify chemicals that are incompatible if mixed.
Identify places/opportunities when incompatible chemicals may be wrongly interacted and manage their confinements.
Avoid using the incompatible chemicals, if possible, in the process as part of Inherently Safer Design. Use alternate compatible chemicals.
Maintain chemicals and materials interaction matrix.

Site specific written down procedure for hot tapping

Even though there are API codes and guidelines available for conducting welding/drilling on live systems, each facility is unique. It is recommended that each site develop an exhaustive procedure for carrying out hot tapping on live equipment at their premises.

Confined Space Entry - Strategies & Effective Practices to Manage and Mitigate Hazards

cms_chrip — Fri, 21 Sep 2018 21:04:58 +0000

Effective Practices to Manage and Mitigate Hazards

Reduce risk by minimizing confined space entry work on vessels connected to equipment still in operation

Consider deferring confined space entry to a future turnaround or outage when inventories of hazardous materials are at a minimum or eliminated.

Properly isolate line or equipment to be worked on

Use blinds or physical disconnects.
Do not use valves as isolation devices.

Line Opening - Strategies & Effective Practices to Manage and Mitigate Hazards

Effective Practices to Manage and Mitigate Hazards

Reduce risk by minimizing work on lines connected to equipment still in operation

Consider deferring line breaking to a future turnaround or outage when inventories of hazardous materials are at a minimum or eliminated.

Properly isolate line or equipment to be worked on

Use of manual valves.
Use of a double-block-and-bleed configuration to ensure manual valves are not leaking through.

Energy Isolation - Strategies & Effective Practices to Manage and Mitigate Hazards

Effective Practices to Manage and Mitigate Hazards

Reduce risk by minimizing work on lines or equipment still connected to operating portion of the process unit

Consider deferring work activities requiring line or equipment opening to a future turnaround or outage when inventories of hazardous materials are at a minimum or eliminated.
Consider deferring work activities on energized electrical circuits to a future turnaround or outage when these circuits can be properly de-energized.

Temporary Instrumentation and Controls Bypass - Strategies & Effective Practices to Manage and Mitigate Hazards

Reduce risk by elimination of bypass events.

• Select safeguards that would not typically need bypassing for start-up.

Hot Work - Strategies & Effective Practices to Manage and Mitigate Hazards

John Vasko — Fri, 10 Nov 2017 17:12:54 +0000

Effective Practices to Manage and Mitigate Hazards

Reduce risk by elimination or substitution; move in-situ work to a less hazardous location

Fabrication and modification outside hazardous areas is prefera-ble with minimal hook up activities in situ.
Consider deferring hot work to a future turnaround or outage when inventories of flammable materials is the plant at a mini-mum or totally eliminated.
Move spark potential equipment such as air compressors outside hazardous areas and use long hoses.
