work permitting process

3 Process Description – Permit to Work System

3.1 General: The permit to work system defines the process to be followed to control

specific types of work (non-routine) that may present hazards or high risk to personnel, compromise the integrity of the facility, pose environmental risks or conflict with other work activities by introducing hazards or risks not previously identified

Three types of permits are included within the permit to work system. (Permit Colors Noted)

• Safe Work Permit (Black on White) • Hot Work Permit (Red on White) • Confined Space Permit (Green on White)

Each Permit Type will: • Be written in English • Have a unique reference number • Be produced in duplicate • Be color coded

2 Responsibilities

2.1 Leadership in Safety is Everyone’s Responsibility. We Must ALL ensure that we are executing work activities per this policy.

2.2 Safety Manager is assigned responsibility for ensuring that the expectations in respect of the Permit to work procedure are adequately defined and documented, and thereafter, that the process is effectively implemented and maintained. In addition they will ensure that employees and contractor personnel are provided with Work Permit training, as appropriate to their roles within the permit system

2.3 Plant Manager is assigned responsibility for ensuring expectations and requirements in respect of the Permit to Work procedure are effectively communicated throughout the facility and that there is strict compliance with the documented expectations

2.4 Employees & Contractors are responsible for working in accordance with the expectations defined within the permit to work system when performing non-routine tasks that have a potential to impact on safe operations at the site and for ensuring that concerns and/or omissions that may lead to potential unsafe operation are brought immediately to management’s attention. Employees are reminded that all personnel have the authority to stop work if there is any reason to believes that an unsafe condition exists or may exist

6.4 Atmospheric Monitoring at Work Site

Gas testing for oxygen and/or flammable or toxic vapors at the work site will be carried out by a competent person whenever hot work is required. The competent person will perform the required range of gas testing necessary to ensure that the immediate and surrounding work area is confirmed as suitable to allow the proposed works to proceed safely

The Permit Issuer will not authorize the work to start if the flammable vapor reading is greater than 0% LEL, or if there are residues of flammable liquids present. If the gas test result is greater than 0% LEL the source of the flammable vapors must be determined and remedial actions taken to eliminate it prior to work commencing

If at any time during the works a flammable vapor of greater than 0% LEL is detected all hot work will stop immediately and the permit withdrawn. The hot work permit will only be re-issued once the source of the vapors has been identified, action taken to eliminate the source and gas testing carried out to confirm 0% LEL

At the time of the workplace risk assessment the Permit Issuer will determine if there is a requirement for continuous gas monitoring to be carried out during the proposed works. If identified as a hazard mitigation measure the Permit Issuer will record the requirement on the hot work permit

Any hot work that is to be performed inside a confined space will require continuous monitoring for flammable vapors within the confined space during the work activity

7 Confined Space Entry Work Permit – Additional Requirements (continued)

7.4 Atmospheric Monitoring – Confined Space Entry

Gas testing for oxygen and/or flammable or toxic vapors at the work site will be carried out by a competent person whenever confined space entry is required. The competent person will perform the required range of gas testing necessary to ensure that the confined space and surrounding work area is confirmed as suitable to allow the proposed entry works to proceed safely

At the time of the workplace risk assessment the Permit Issuer will determine if there is a requirement for continuous gas monitoring to be carried out during the proposed works. If identified as a hazard mitigation measure the Permit Issuer will record the requirement on the confined space entry and/or hot work permit

If mechanical ventilation system is being used to remove potentially harmful and/or flammable vapors and maintain a continuous airflow, it is essential that the ventilation system is isolated at least 15 minutes before carrying out gas testing to ensure a representative sample is tested. Once a representative sample has been obtained the ventilation system can be re-energized

Any hot work that is to be performed inside a confined space will require continuous monitoring for flammable vapors within the confined space during the work activity

Entry into a confined space known to contain an inert atmosphere (nitrogen blanketed) is only allowed if the entry is to be carried out by specialist contractors using specialist equipment and authorization to proceed is granted by the site manager following consultation with the Safety Manager
