HSE LIFETHE NATIONAL OIL&GAS INDUSTRY STANDARD FOR PROFESSIONALS

HIGH PRESSURE

Work safely or don’t work at all There are strict procedures when working on installations and systems. After all, there’s a risk for noxious substances to be released. Therefore read the Permit to Work carefully and check if the described control measures have been taken. Then take the precautionary measures which belong to your job.

Speaking the same clear language regarding Health, Safety and Environment, and harmonisation of regulations by focusing primarily on agreements between companies and contractors.

That is the goal the member parties of HSElife Unio pursue.

HIGH PRESSURE

Gas is extracted from the ground in a highly pressurized state. When an installation is in full operation, all pipes and storage facilities are under high pressure. Pressures of up to 200 bar are not exceptional. According to legislation, ‘high pressure’ technically occurs from a pressure of 100 bar. However, pressures of less than 10 bar can also be dangerous.

WHAT ARE HIGH PRESSURE SITUATIONS?

Examples of situations and installation parts were high pressure can occur:• wells, barrels and fittings• gas and liquid carrying pipes• hydraulic and pneumatic high pressure hoses

HIGH PRESSURE

WHAT IS THE CORRECT WORKING METHOD?

Ensure that any installation parts, pipes, barrels or tanks on which you are going to work are free of liquid, gas and/or pressure before opening.

Always inspect hoses, fixings, couplings and safety measures (e.g. safety lines or cables) before use.

Use hydraulic and pneumatic equipment in the prescribed way.

Roll up hoses you are not using and store immediately.

Determine the correct equipment to be used in the work permit.

Report all spills directly to the CCR. Never touch a spill and never undertake independent action.

HIGH PRESSURE

WHAT ARE THE HAZARDS OF SPILLS?

Serious injury from inhalation or bodily contact.Explosion hazard through friction (suspended particles)Explosion hazard through static electricityExplosion hazard through mixing with air (oxygen)Irreparable damage to the environment

HIGH PRESSURE

PERSONAL PROTECTIVE EQUIPMENT

Always use the correct personal protective equipment.• prescribed clothing• safety footwear• helmet• safety glasses• gloves

Use it in the prescribed way and keep it in good condition.

Extra protective equipment may be required for work that entails a specific risk. This equipment is recorded in the work permit. All persons are required by law to use the prescribed protective equipment.

HSE LIFE

LMRA Last Minute Risk AnalysisASK YOURSELF THE FOLLOWING QUESTIONS: Do I know what I need to do? Is the workplace safe? Are all safety procedures explained to me? Am I familiar with the hazards of my work (assignment)? Do I have proper safety equipment (PPE)? Do I have the right tools? Are my tools certified? Have I done everything possible to minimise the risk? If anything goes wrong, do I know what I’m supposed to do?

All YES: start (of continue) the activity.If NO or in doubt: go to your supervisor and discuss the situation.
