Please note that : All confined spaces must be considered “A” category until tested and verified as a “B” category. 71 71  Classification: Tasnee - General Information Confined Space Requirements ❑ Ventilation Requirements for Confined Space. ❑ For horizontal exchanger which are opened from both ends during the confined space entry, ventilation plan is not required. ❑ Do Not use Nitrogen to ventilate confined spaces, as this could lead to oxygen enrichment/deficiency of the space. ❑ Only pneumatic driven blower, fans and air movers are allowed to ventilate the confined spaces. ❑ Fans and air movers shall be ensured that it is electrically bonded and grounded to the vessel. ❑ Air conditioners can be installed as an alternate of ventilation wherever it is convenient. Air Conditioners capacity will be used to identify the ventilation rate required. However, in case of use of Air Conditioners for ventilation, Air Movers shall be kept ready to use in case of Air Conditioners shutdown or any emergency. ❑ A positive means of ventilating confined space shall be established and kept operated the entire time while work is in progress. ❑ Following tips shall be considered for ventilation: ❑ Positioning of mechanical aspirators, drawing of fresh air, routing of exhaust air. ❑ Ventilation plan shall be prepared and approved as per IMRS 13-02-01-23 Ventilation plan. ❑ Ventilation of a space will also vary depending on the type of material that is being ventilated from the space. 72 72  Classification: Tasnee - General Information ❑ Rescue plan Preparation and requirements for confined Space Entry. Confined Space Requirements If hazard cannot be mitigated, then Rescue shall be prepared prior to entry. ❑ When required ? ❑ Rescue Plan is mandatory for all Confined Space entry types. ❑ Rescue Plan shall consider the following: ❑ The hazards outcome of the JSA. ❑ The location of the work. ❑ Number of workers, even if there will be only single worker. ❑ The duration and period the of work. ❑ The resources needed for the rescue and the number of people required. ❑ Internal Configuration ❑ Elevation ❑ Manway Size ❑ Confined Space Access 73  Classification: Tasnee - General Information ❑ It is important to consider the following conditions when planning for a confined space entry work. ❑ Internal Configuration: Confined Space Requirements ❑ Confined space contains some type of obstruction that a rescuer would need to maneuver. For example, a baffle or mixing blade, large equipment, such as a ladder or scaffold, brought into the confined space for work purposes would be considered an obstruction if the positioning or size of the equipment would make the rescue difficult. ❑ Elevation: ❑ Elevated a confined space entry where the entrance or opening is above ground by 4 feet or more. This type of confined space usually requires knowledge of high angle rescue procedures because of the difficulty in packaging and transporting a victim to the ground from the confined space. ❑ Non-elevated a confined space entry with the entrance located less than 4 feet above ground. This type of space will allow the rescue team to transport an injured worker normally. ❑ Manway Size: ❑ Restricted a Manway of 24 inches or less in the smallest dimension. Manways of this size are too small to allow a rescuer to simply enter the space while using SCBA. The Manway size is also too small to allow normal spinal immobilization of an injured worker. ❑ Unrestricted A Manway of greater than 24 inches in the smallest dimension. These Manway allow relatively free movement into and out of the confined space. ❑ Confined Space Access: ❑ Horizontal the Manway is located on the side of the confined space Use of retrieval lines could be difficult. ❑ Vertical the Manway is located on the top or bottom of the confined space. Rescuers must climb down or up the permit space respectively to enter it. Vertical portals may require knowledge of rope techniques, or special patient packaging to safely retrieve a downed entrant. 74  Classification: Tasnee - General Information ❑ Rescue plan Preparation and requirements for confined Space Entry. ❑ All confined Space Entry shall have a developed Rescue plan as per the method (using Rescue plan form) how to enter, exit, escape, and rescue personnel working in Confined Space Requirements confined spaces it shall be done during the job planning phase and before confined entry Permit issuing. ❑ Confined spaces on a site visit shall be assessed to determine what special equipment or procedures may be involved when conducting a rescue operation ❑ Rescue Plan shall be prepared by task execution Supervisor or above from Tasnee team and contractor. ❑ Familiarize all execution team with the approved rescue plan before starting the activity. ❑ Provision of Rescue Equipment: ❑ Rescue Equipment shall be suitable and sufficient to respond to an emergency in a timely and safe manner. for example, rescue equipment may include: ❑ Full body harness with retrieval line attached. ❑ Hand-cranked mechanical winch and tripod (required when entrant is five feet or more below the entrance). ❑ Lifeline. ❑ Explosion-proof lighting. ❑ Breathing apparatus. ❑ Stretcher. ❑ Based on the type of the confined spaces entry and the condition of the work and location rescue plan need to be devolved. 75
