Activity is not complex

– Examples of complex activities: Integration between multiple work groups; tasks that cannot be performed from memory

Steps performed out of sequence, inadvertently omitted, or performed erroneously are recoverable without significant consequence.

– Examples of significant consequence: Errors have an immediate effect and/or significant impact on personnel health and safety or plant or equipment operability; consequences of errors will not be detected and/or corrected prior to the end of the activity and declaration of operability; error in performance will affect the Hazards Analysis (e.g., AHA, JHA, etc.) or USQ that was done on the procedure, and error could result in a new activity that wasn’t analyzed

Procedure does not require documentation of completed steps

– Examples of steps requiring documented completion: TSR; Criticality; QA Hold Point; RPD Action Step;

Independent Verification; Second Person Verification; Packaging and Transportation

Warning, Caution, or ALARA statements within the procedure do not warrant requiring the procedure be in hand (e.g., procedures do not include hazard controls that are outside of Individual Hazards Analysis (IHA) scope).

If the performance of the procedure meets all of the criteria listed above, then the procedure is properly categorized as a Reference Procedure.

The procedure is technically accurate and can be performed as written

If the procedure cannot be performed as written, then the procedure deficiencies must be corrected prior to release.

The required prerequisite training and/or position qualification are adequate to ensure the user has the skills and knowledge to perform the procedure in a logical sequence to accomplish the task.

APPROVAL AND CONCURRENCE

I have verified that the Reference Procedure is appropriately categorized, technically correct, and personnel are trained to allow performance of the procedure in a logical sequence.

Reviewer (print / sign / date)

CONCURRENCE

Procedure does not require entry of information into the procedure (in any section and/or attachment).

This criterion does not apply if the procedure in review requires completion of a separate data sheet or form.

RESPIRATOR DRYER OPERATION Effective Date: 03/18/2016 Type-Class: Tech-REF Page: 1 of 3

1.0 INTRODUCTION

1.1 Purpose

Provide instructions for operating the respirator dryer at the Satellite Respiratory Equipment Facility (SREF) located in the 766-H Training Facility and at the Respiratory Equipment Facility (REF) located in Building 705-C.

1.2 Scope

This procedure applies to the use of the respirator dryer in the REF when drying respirator equipment.

This is a Reference procedure. The user is not required to have this procedure present while performing the activity.

2.0 GENERAL INFORMATION

2.1 Responsibilities

1. REF Personnel are responsible for operating the respirator dryer.

2.2 Information

1. The respirator dryer is a front-loading cabinet containing a chamber into which dollies (holding racks containing respiratory equipment for drying) are placed.

2. The respirator dryer removes moisture from the respirators by using high-velocity, low-temperature air (120°F) in a laminar linear cross-flow drying chamber. Air recirculates via a 1225 cfm, 3/4-hp blower and is heated by two heater banks. An indicating controller controls temperature. High limit protection is set at 200 degree Fahrenheit. If the red light in the upper left hand corner of the high limit controller is illuminated, the high limit temperature has been tripped, notify the REF Lead to reset the high limit controller by pressing the reset red button.

3. The heated air flows across the drying chamber over the respiratory equipment and back to the blower chamber. Moisture-laden air is removed from the drying cabinet via a 4-inch exhaust duct through the top of the dryer.

Makeup air enters the blower chamber from ambient room air.

4. For energy conservation, the two heater banks can be controlled independently by switches on the control panel. Heat bank operation is indicated by the red light adjacent to the switch. An illuminated red panel light indicates which heater bank is on. The heaters cannot be energized unless the recirculating blower is operating. A timer controller shuts the dryer down after a preset time, normally four hours.

2.2 Information, (cont.)

5. The dryer chamber accommodates two rack-handling dollies at one time with each dolly capable of holding six loaded respirator racks. Each respirator rack holds an average of six respirators.

3.0 PRECAUTIONS AND LIMITATIONS

3.1 Safety

1. A hazard analysis has been performed on this task. (INF-19978)

2. Comply with all facility safety rules per Manual 8Q, Employee Safety.

3. Proper lifting techniques are outlined in Manual 8Q, Procedure 12, General Site Safety Requirements.

4. Handles shall be used to open and close doors on respirator dryer.

5. Pinch points are hazards when closing dryer doors and loading racks on dollies.

4.0 PREREQUISITES

None

5.0 PERFORMANCE

5.1 Respirator Dryer Operation

1. PRESS the recirculation fan START button. The amber pilot light indicates electrical operation.

NOTE

Either one or both of the heater banks can be used. The temperature controller is set so that the heater banks, which cycle automatically, maintain the dryer temperature at about 120°F.

2. WHEN the fan begins operation, THEN

ENSURE that the heater bank toggle switch(es) is ON.

3. PLACE the racked respiratory equipment inside the drying chamber for drying, THEN

CLOSE doors tightly.

5.1 Respirator Dryer Operation, (cont.)

NOTE

A timer controller shuts down the dryer after four hours in the REF. This feature is not used on the dryer in the SREF at 766-H.

4. WHEN the dryer shuts down or is turned off, THEN

REMOVE the dried respiratory equipment if dry.

NOTE

Pressing the OFF button will turn off the dryer.

5. ENSURE the dryer is turned off at the end of each day even if respiratory equipment is not dry.

6. RESTART the dryer the next working day if respiratory equipment is not dry.
