If help is needed, the operator should contact the Hines Police Department via the two-way radio.

The on-duty operator will initiate a call to the Hines Police Department via the telephone at extension 22379 at the beginning of the shift and the middle of the shift to ensure that the ability to perform assigned duties has not been impaired due to accident or other event.

In the event the operator does not contact the Hines Police Department at the beginning or middle of the shift via telephone, the Police Department will initiate a phone call to the Boiler Room Plant at extension 22387. If there is no answer, the Police will send an Officer to the Boiler Plant to physically check on the operator.

It is VHA policy that Boiler Plant Operators, Boiler Plant Supervisors and Boiler Plant Service Managers successfully complete appropriate Boiler Safety Education.

A 12-part video and handbook on the boiler safety education program titled "Keep it Steamin':

Keep it Safe" has been developed by the Employee Education System (EES) as the basic VHA boiler safety education course.

The 12-part course is mandatory for all VHA boiler operators and their immediate supervisors.

Parts 10-12 are mandatory for Chief Engineers, Facility Managers, and Safety Specialists.

NOTE: Nothing in this Directive is to be construed to mean that the 12-part "Keep it Steamin':

Keep it Safe" courses are to be the only educational programs for boiler plant staff

VA Hospital Policy Memorandum 578-12-138A-078 (R-1) Hines, IL. 60141 February 1, 2018

BOILER PLANT OPERATIONS

1. PURPOSE: This Hines VA Hospital; Engineering Service policy on the operation of the Boiler plant at Hines VA Hospital campus.

2 POLICY: It is Hines VA Hospital policy that the Boiler plant located at Hines campus be operated in a safe and economical manner recognizing its importance and the potential for pressure vessel and/or furnace explosion. Physical plant safety is paramount and is the first priority for Hines VA Hospital Boiler plant operations.

The Boiler plant is essential to the operation of the medical center providing steam and hot water required for sanitation, infection control and a healthful environment for the delivery of health care.

Boiler plant safety is dependent on well-trained operators, properly functioning safety equipment, proper operational procedures, well-maintained boilers and support equipment, and a commitment to continuous quality improvement.

3. PROCEDURES: All safety devices installed on the physical plant boilers, or installed as part of the fuel systems, steam distribution systems and condensate return systems, shall be periodically tested to ensure their proper function in accordance with the VHA Boiler Plant Safety Devices Testing Manual. Results of the testing will be documented on the Boiler Safety Devices Sheet. Boiler plant safety is paramount and is the first priority for Boiler plant operations. Boiler plant safety shall not be compromised in order to maintain steam service.

a. Operational rounds are an integral part to Boiler plant safety and are the first line of defense against a catastrophic failure of a boiler safety device. Operational rounds shall be made on the hour by all shifts and shall include a complete cataloging of the major operating equipment.

The logbook will be reviewed and initialed by the oncoming operator and filled out throughout the shift with the following information but not limited to;

(1)Any situation that requires action on the part of the operator other than routine maintenance activities (i.e. trouble calls, disaster drills, fire alarms, bomb threats, etc.)

(2)Name of caller, time called & reason for call.

(3)Equipment that is off line due to breakdown or maintenance will be listed with a cause and potential repair date.

b. The safety of the Boiler Room Operator is of paramount importance. All Boiler

Plant Operators on duty during the off hours shall adhere to the following:

(1)During the following shifts 12:00 a.m. to 8:00 a.m. and 4:00 p.m. to 12:00 a.m. including all weekend shifts and Federal holidays, the on-duty operator will carry either a cell phone (with police department programmed within) or a two-way radio issued to the Boiler Plant for his safety. If help is needed, the operator should contact the Hines Police Department via cell phone or two-way radio.

(2)The on-duty operator will initiate a call to the Hines Police Department via the telephone at extension 22379 at the beginning of the shift and the middle of the shift to ensure that the ability to perform assigned duties has not been impaired due to accident or other event.

(3) In the event the operator does not contact the Hines Police Department at the beginning or middle of the shift via telephone, the Police Department will initiate a phone call to the Boiler Room Plant at extension 22387. If there is no answer, the Police will send an Officer to the Boiler Plant to physically check on the operator.

c.The Boiler Plant Operator will review and acknowledge all alarms. All active alarms will be entered into the log when action is required and the action taken. At the change of shift all alarms will be signed over to the oncoming operator who will accept responsibility for the corrective action required.

d. Notification of a non-functioning safety device — Normal Operating Hours: The on-duty operator upon discovery of a non-functioning safety device shall immediately notify the Boiler Plant Foreman or the Chief of Maintenance and Repair. If the safety device cannot be readily repaired, or replaced, thereby, rendering the boiler out-of-commission. The on-duty operator shall log the findings in the daily log. After Normal Hours of Operation: The on-duty operator shall log the findings in the daily log. The oncoming dayshift operator shall notify the Boiler Plant Foreman or the Chief of Maintenance and Repair of the non-functioning device.

e.At any time where an emergency condition(s) exist that would compromise boiler plant safety, (i.e.) boiler safety device is recognized as non-functional) or reduction in steam-generating capability, the on-duty operator shall contact the Boiler Plant foreman for proper authorization to call in a contractor for repairs, and authorization to implement steam load shedding procedures. If it is determined that boiler operations cannot be readily restored, the Chief of ENGINEERING or the designee will notify the Medical Center Director.

f. Boiler plant operators shall be knowledgeable of the location, purpose, and proper functioning of all physical plant safety devices. Physical plant operators shall at no time leave any high-pressure boiler (above 15psig) unattended except for brief moments to use the restroom In addition, unqualified persons shall not relieve physical plant operators.

g.Physical plant operators shall participate in an ongoing training program to develop, maintain, and regularly refresh proficiency in safe boiler operations and shall be proficient in properly performing the following:
