The aim of GWO’s CoHE Pressure Fluid Safety training module is to enable the participants to support and care for themselves and others while working with and in the vicinity of pressure fluids in the wind industry and to perform assigned tasks safely and efficiently. Upon successful completion of GWO’s CoHE Pressure Fluid Safety Module, the participants will be able to reduce the associated risks to and work safely with pressure fluid tasks in the wind industry by being able to select the correct and required PPE for working with hydraulic fluids and fluids under pressure, using safe work practices and establishing a safe work condition when working with and in the vicinity of pressure fluids in the wind industry.

The aim of the GWO CoHE Pressure Fluid Safety Refresher Training is to refresh the participants ability to manage and control the risks related to hazardous pressure fluids in the wind industry and to safely control work when in the vicinity of hazardous pressure fluids or when working on systems and equipment containing hazardous pressure fluids. This training refreshes participants´ ability to act safely, support and care for themselves and others, while working with, and in the vicinity of hydraulic fluids and fluids under pressure in the wind industry and to perform assigned pressure fluids work tasks safely and efficiently in the role of a Qualified Person.

11.1 Aims and objectives of CoHE Pressure Fluid Safety Refresher Training

Note The GWO CoHE Pressure Fluid Safety Module is aimed towards improving the participants´ ability to “work safely” with pressure fluids. This means that the CoHE Pressure Fluid Safety Module is not aimed at improving candidates´ technical knowledge, skills, and abilities regarding pressure fluids. Participants should already possess these technical knowledge, skills, and abilities before attending the module. Similarly, it is not the intention of the GWO CoHE standard to promote the acquisition of advanced knowledge, such as troubleshooting. Note:

Lesson 1 - Introduction to the training ELEMENT 1.7 - HUMAN FACTORS

Note Throughout this training in all lessons the instructor should ensure a holistic integration of human factors where relevant. For incident lessons and safety information shared by global energy companies, as inspiration in scenario development, please visit - https://toolbox.energyinst.org/

The instructor shall: 1.7.1Facilitate an open and honest discussion on workplace safety and personal responsibility, linked to stories about the impact on individuals who decided to "have a go" as opposed to working within the SSOW. Key points to challenge parƟcipants on: a. Why do they think we need a safe system of work? b. Is the SSOW in place to safeguard teams, demonstrate compliance or satisfy customer expectation? Is it there to protect you and what you provide for your loved ones? c. How could you or your coworkers be impacted by an incident? Will financial compensation resolve that? d. If an incident occurs, how do you prove you have performed your role correctly? e. Explain that adhering to a SSOW creates a record of evidence to illustrate your professional behaviour - without that record nothing exists ...it is not what you know...it is what you can prove 1.7.2 Present how human factors have an influence on accidents in the wind industry (relevant statistics may be given) 1.7.3 Lead a discussion about the role of the individual in improving human performance, and how this improvement can benefit safety when working in the wind industry, by considering factors like:
