1 BTCP/BTRF Standbys (Owner: Risk Management Section Supervisor) Site Safety Standard 5500 Introduction Scope The purpose of this standard is to specify detailed roles and responsibilities of Standby personnel required by permitting procedures. Table of Contents Topic See Page Introduction 1 Definitions 1 General s 2 Responsibilities 3 General Roles and Responsibilities Applicable to All Standbys 3 "Standby Specific" Roles and Responsibilities 5 Breathing Air Bottle Watch 5 Breathing Air Standby 6 Compressed Air Watch 6 Electrically Qualified Standby 7 Confined Space Entry Hazard Watch 7 Fire Watch 9 Hazard Watch 9 Process Watch 10 Definitions Acid Gas - A process stream that contains 20% (200,000 ppm) H 2 S. Combustible Combustible materials includes anything that will burn but is not readily ignited. Paper and wood are ideal examples of combustible materials. Flammable Flammable materials can easily catch fire under normal circumstances with a minimal ignition source. A single spark is sufficient. Propane, gasoline, kerosene are ideal examples of flammable materials. Immediately Dangerous to Life or Health (IDLH) - An atmosphere that poses an immediate threat to life, would cause irreversible adverse health effects, or would impair an individual s ability to escape from a dangerous atmosphere.

2 Standbys Site Safety Standard 5500 Definitions, Continued Standby - A person designated to monitor, control, and/or warn persons of hazardous or emergency conditions that could affect their safety. The term "Watch" is a type of Standby (e.g., Fire Watch). General s Item Determine if a Standby is Required 1 Anyone involved in the activation of the permit may determine the need for a Standby and the Standby requirements. The need for a Standby should be based on (1) permitting requirements and (2) an assessment of the potential hazards that could develop during the course of work. The types of Standbys are listed below: Breathing Air Bottle Watch Breathing Air Standby Compressed Air Watch Electrically Qualified Standby Entry Hazard Watch Fire Watch Hazard Watch Process Watch Permitting Responsibilities 2 As part of the permitting process, the Permit Recipient is responsible for: Discussing Standby requirements and expectations with the Standby. Ensuring that the Standby is qualified to serve in this position and understands his/her roles and responsibilities. Ensuring that the Standby understands precautions, potential changing conditions, hazardous materials and equipment in the area, and any other pertinent safety information applicable to the job being performed. This should include a discussion on both routine and emergency conditions. NOTE: The ExxonMobil Equipment Operator/FLS may choose to be involved in this discussion. Rev. 6, 09/16 Page 2 of 11

3 Standbys Site Safety Standard 5500 General s, Continued Item Permitting Responsibilities, Continued 3 If the Standby works for a different company than the Permit Recipient(s) for which they are providing standby duty, then the Standby must be issued a General Work Permit to perform their Standby duties. 4 The Standby(s) must sign the Standby section of the Permit. This is also required when the Standby works for a different company and has received their own General Work Permit to perform their Standby duties. Exception: Standbys not required as part of the permitting process must not sign on the permit. For example, if the permitted work group chooses to voluntarily wear Breathing Air when it is not required, the Breathing Air Standby and Breathing Air Bottle Watch (when hose line is used) must not sign on the permit. A Standby may perform Standby duties on more than one permit at one location if agreed to by all parties involved. 5 Only required Standbys may sign the Standby section of the Permit. Extra Standbys may not sign the Permit. 6 The Standby may not perform any other duty that would distract from his/her primary Standby responsibilities. However, one person may be used to perform two Standby functions as long as it will not prevent the person from being able to fulfill all the responsibilities of those functions. 7 The Standby must follow transfer procedures if replaced. See Permit Transfers in SSS-5200, Basic Permitting Principles. Responsibilities General Roles and Responsibilities Applicable to All Standbys 1 Understand the roles and responsibilities of the Standby and execute them accordingly. 2 Understand the job scope and the safety implications of the task to be done. Rev. 6, 09/16 Page 3 of 11

4 Standbys Site Safety Standard 5500 General Roles and Responsibilities Applicable to All Standbys, Continued 3 Arrange for, and understand, the methods of communications to be used at the job site (e.g. radios, horns, alarms, etc.). At a minimum, each Standby must: Have access to a radio at the job site that permits communication with a person who has access to an in-plant telephone to summon help (4-3600) in the event of an emergency. NOTE: is accessible only with the in-plant phone system; therefore mobile phones do not meet this requirement. Establish a clear understanding with the people working off the permit on the following: The methods that will be used to communicate with each other during the work (e.g. radios, horns, etc.) The method(s) that will be used to summon help in the event of an emergency Clearly understand how to promptly communicate the need for emergency assistance to ExxonMobil. Clearly communicate any job-related issues to the ExxonMobil person responsible for the area and/or equipment (this is the group that approves work on the equipment). 4 Clearly understand the unit/area alarms and the procedures/actions to take should they activate (e.g. evacuate personnel, etc.). 5 Ensure Standby equipment is in good working order. 6 Understand precautions, potential changing conditions, hazardous materials and equipment in the area, and any other pertinent safety information applicable to the job being performed. 7 Must be able to monitor entire area that may be impacted by the work being performed. As an example, if hot work is being performed at an elevation, the Standby must be able to monitor all locations that could be impacted by falling sparks. This may result in multiple Standbys being required. 8 Ensure applicable barricades are in place and prevent unauthorized entry. Rev. 6, 09/16 Page 4 of 11

5 Standbys Site Safety Standard 5500 General Roles and Responsibilities Applicable to All Standbys, Continued 9 Monitor the well being of all designated personnel. 10 Summon help in the event of an emergency. Assist in rescue only if authorized, trained, and qualified. 11 Rescue cannot be started in confined spaces or regulated areas until trained and qualified help has arrived. Breathing Air Bottle Watch "Standby Specific" Additional Roles and Responsibilities In addition to the General Roles and Responsibilities for all Standbys, each specific type of Standby must comply with the following additional Roles and Responsibilities. 1 Required for all work where Breathing Air hose line equipment is used. 2 Ensure an adequate air supply (including air pressure) is maintained to workers using hose line breathing air equipment. 3 Be stationed at the breathing air bottles. If a regulator manifold is employed, a Breathing Air Bottle Watch must be present at that location as well. NOTE: For Breathing Air supplied by an onsite compressor system (e.g. Cobra System) or tube trailer, a Breathing Air Bottle Watch is not required at the compressor or trailer, but there must be one at each regulator manifold. 4 Be knowledgeable of how to maintain air supply and the respiratory protection equipment in use. 5 Stop work and evacuate personnel if air pressure falls below the low-pressure alarm setpoint. Bottles may not be changed while personnel are working under breathing air (i.e. when using multiple bottles, all must be manifolded together and open at the same time). 6 Prevent fouling and tangling of airlines or lifelines.
