Template Description for a Permit to Work This includes a template which must be developed by the training provider into a permit to work for use during CoHE training. It details the required elements in a permit to work and some text as a suggestion of what should be included in each section.

Note Please use the terms and definitions from the GWO CoHE Training Standard rather than terms and definitions used in the referenced standards and norms above. The terms and definitions in the GWO CoHE Training Standard were made for the sake of creating this global training standard based on the common ground of different recognised standards. Participants could end up working under any variety of safe system of work, so the language and terminology have been chosen to be as applicable as possible across the most common systems of work.

4. COHE ROLES AND RESPONSIBILITIES 4.1 CoHE Basic Safety Module Note The following roles are for general reference and are not fully aligned with any standard or safe system of work. These definitions were made for the sake of creating this global training standard based on the common ground of different recognised standards. Roles Responsibilities (limitations to what can and cannot be) Qualified Person A person who has demonstrated skills and knowledge related to the construction and operation of equipment and installations specific to their work and has received safety training to identify the hazards and reduce the associated risk. Examples of responsibilities: performing isolations and testing, creating a safe work condition for others to work under, lead job briefing, lead and supervise work parties. Ordinary Person / Unqualified Person A person who is not a Qualified Person and does not have any responsibilities, given that this person generally needs control, instruction, and supervision to carry out assigned working activities. Additionally, a person who can be instructed to apply his personal lockout equipment in accordance with a company specific Lockout-Tagout program, procedures, and rules.

ANNEX 3 - TEMPLATE DESCRIPTION FOR A PERMIT TO WORK

ANNEX 2 - TEMPLATE DESCRIPTION FOR A PERMIT TO WORK This annex includes a template which must be developed by the training provider into a permit to work for use during the Control of Hazardous Energies Standard. It details the required elements in a permit to work and some text as a suggestion of what should be included in each section. The template is incomplete in some areas and is therefore not intended to be used as is. This permit to work must be completed at the point of work. A permit to work must not be filled out retrospectively and/or by a 3rd party not directly involved in the work performed. A permit to work must be filled out clearly. Note Please emphasise to the participants that a permit to work will vary depending on the company and the site of the work taking place, so the participants should seek out and comply with company specific rules and procedures along with national and regional legislation.

This annex includes a template which must be developed by the training provider into a Permit to Work for use during training in the Control of Hazardous Energies Standard. The template details the required elements of a Permit to Work and some text as a suggestion of what should be included in each section but is incomplete in some areas and is therefore not intended to be used as is. Training providers may use an actual Permit to Work of a relevant type from in the wind industry, such as an employer specific permit, as long as it provides the basic features included in the template to facilitate the learning activities. Note Basic principles for carrying out activity under a Permit to Work include: • A permit to work must be completed at the point of work. • A permit to work must not be filled out retrospectively and/or by a 3rd party not directly involved in the work performed. • A permit to work must be filled out clearly. A permit to work will vary depending on the company and the site of the work taking place, so the participants must seek out and comply with company specific rules and procedures along with national and regional legislation.

8.1 Aims and Objectives of CoHE Electrical Safety Initial Training 8.1 Aims and Objectives of CoHE Electrical Safety Initial Training

11.1 Aims and Objectives of the CoHE Electrical Safety Module The aim of GWO’s CoHE Electrical Safety training module is to enable the participants to support and care for themselves and others while working with, and in the vicinity of, electricity in the wind industry and to perform assigned electrical work tasks safely and efficiently. Upon successful completion of GWO’s CoHE Electrical Safety Module, the participants will be able to perform electrical work safely within the wind industry using electrical PPE, precautionary techniques, and electrical safety safe working practices to reduce the associated risks to the electrical hazards.

The aim of the GWO CoHE Pressure Fluid Safety Initial Training is to enable the participants 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 prepares participants to act safely, support and care for themselves and others, while working 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.

8.1 Aims and Objectives of CoHE Electrical Safety Initial Training 8.1 Aims and Objectives of CoHE Electrical Safety Initial Training

Note The GWO COHE Electrical Safety Module is aimed towards improving the participants´ ability to “work safely” with electricity. This means that the CoHE Electrical Safety Module is not aimed at improving candidates´ technical knowledge, skills, and abilities regarding electricity. Participants should already possess the needed 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

The training is not aimed at improving technical capabilities regarding electricity or pressure fluid systems or the acquisition of advanced knowledge, such as troubleshooting. Before attending CoHE training participants should already possess technical knowledge, skills, and abilities in electrical or pressure fluid systems. V4 - V5 02.03.26
