1. Background This project will repair and inspect three fire suppression systems at James A. Garfield National Historic Site.

All three structures need existing fire suppression inspected for readiness and capability to hold a UL listed antifreeze. Antifreeze needs to be UL listed, have a temperature rating of -13 degrees Fahrenheit for upcoming 2022 NFPA deadline for antifreeze systems.

Location #1: The Main House fire suppression system is a water system with full antifreeze holding approximately 320 gallons in piping. The Main House system also supplies suppression services to the neighboring Campaign House Location #2. These systems are connected by underground fire suppression piping.

Location #3 Visitor Center is a water-based system with an antifreeze loop holding an unknown amount of antifreeze. All three systems will be repaired, brought up to code as per SOW and applicable NFPA codes and have UL Listed antifreeze installed.

The Main House fire suppression system had exterior sprinkler heads freeze, burst the pipe, and expelled the antifreeze. The system was shut down in February of 2021, broken head was replaced and the remaining diluted mixture was drained into two 270 gallon holding tanks for an approximated 540 gallons (there was existing fluid in the tanks before failure), the tanks are integrated into the suppression system and completely full. Due to weather conditions and upcoming code changes for antifreeze requirements on September 2022, the system remains shut down. In May 2021 it is planned to activate the system with water only until a permanent fix is made.

The Visitor Center has a water system with an antifreeze loop that holds an unknown amount of antifreeze. This system is currently out of NFPA code and will be repaired.

All three systems will be repaired and inspected per applicable NFPA code, to include the 5-year internal inspection.

2. Objectives At the completion of the project, three fire suppression systems and their alarm function will be 100% operational, inspected and completely NFPA compliant.

1.2 Changes

October 2020. Interim revision. Revisions were made addressing recommendations for inspection, testing and maintenance of hybrid fire extinguishing systems (Sections 2.11.4.1 and 2.11.4.2.)

2.0 LOSS PREVENTION RECOMMENDATIONS

2.1 Introduction

Automatic fire protection systems are a reliable and effective means of mitigating fire risk, provided the systems are properly designed, installed, and maintained. After system installation and acceptance testing, implementing an ITM program will help ensure the fire system can be depended on to protect your facility.

It is equally important that, when inspection, testing, and maintenance operations are carried out, proper planning and impairment procedures are followed to minimize the amount of time systems are out of service, and to have in place a means to readily return the system to service in the event of an emergency during these procedures. Coordination with the in-house emergency response team, as well as close supervision of any outside contractors performing these services, are essential to minimize the hazard involved and reduce the risk to the facility.

Tables 1-10 contain both frequency-based and event-driven ITM activities. Frequency-based activities are listed with a baseline frequency, and references to any additional technical detail are included in the tables.

Appendix D contains sample forms to serve as checklists and/or to document the results of ITM activities.

These forms may be customized to meet the individual needs of a facility.

2.1.1 Fire Protection System Impairment Precautions

Routine inspection, testing, and maintenance of fire protection equipment can create an impairment to the system, and these impairments need to be properly managed. Whenever fire protection water supplies, sprinklers, fire pumps, or special protection is impaired, an unusual fire protection hazard exists and specific fire prevention procedures are necessary. Follow procedures based on the FM Global Red Tag Permit System

Fire Protection System Inspection 2-81 FM Global Property Loss Prevention Data Sheets Page 3

(or equivalent) and as outlined Data Sheet 10-7, Fire Protection Impairment Management, to ensure complete precautionary measures are taken and ignition sources are controlled.

2.2 Inspection, Testing, and Maintenance Programs

2.2.1 Use trained personnel or qualified contractors to perform ITM.

2.2.1.1 Provide initial and annual refresher training for facility personnel performing ITM. Ensure personnel are knowledgeable on: location of critical system components (e.g., control valves); system operation; relevant procedures; and identifying abnormal conditions that may render a system inoperable. Train and maintain a competent group of back-up facility personnel in the event primary personnel suddenly become unavailable (e.g., illness or transfer).

2.2.1.2 Select qualified contractors who meet the requirements of local codes and authorities having jurisdiction. Supervise fire protection contractors performing ITM in accordance with Data Sheet 10-4, Contractor Management.

2.2.2 Document completed ITM activities. At a minimum, include the following in the documentation:

• Specific systems and equipment covered

• Type of ITM

• Results

• Comments or corrective actions needed

Retain ITM documentation for auditing by management and/or authorities having jurisdiction for a minimum of one year.

2.2.3 Audit the fire protection system ITM program.

A. Establish an audit frequency based on facility conditions, such as the past program audit results, but at least annually.

B. Review program documentation, including policies and procedures (to ensure they remain current);

completed ITM documentation (for thoroughness and unresolved corrective actions); record retention;

timeliness of ITM work-order completion and outstanding work-orders; and training.

C. Witness employees or contractors performing ITM activities.

2.3 General Inspection, Testing and Maintenance Practices

2.3.1 Use an impairment management program (FM Global Red Tag Permit System or equivalent) when protection is taken out of service to conduct ITM. Refer to Data Sheet 10-7 for examples of fire protection systems impaired during ITM.

2.3.2 Incorporate an impairment alert into ITM work orders, procedures, or contracts if the activity renders a protection system out of service.

2.3.3 Conduct alarm device testing that initiates fire alarms outside of normal operating or production hours to limit disruption within the facility. Prohibit the use of jumpers or forces to temporarily bypass an alarm device that initiates a fire or supervisory alarm to facilitate testing.

2.3.4 Conduct alarm device testing that initiates an automatic shutdown of building’s system or process equipment during planned or unplanned maintenance outages. However, if bypassing an alarm device is unavoidable, either of the following alternatives are tolerable if an impairment management program is also used.

A. Install a lockable switch with exterior position indication (i.e., open or closed) in the alarm circuit. Locate the isolation switch near the alarm device, allowing for periodic inspection of the switch conditions (secured and closed position).

B. Use a jumper or force to temporarily bypass an alarm device.

2.3.5 Use an impairment management program (FM Global Red Tag Permit System or equivalent) when fire protection systems are discovered to be out of service through ITM. Inoperable components, poor system

2-81 Fire Protection System Inspection Page 4 FM Global Property Loss Prevention Data Sheets performance, and poor physical condition are instances in which a fire protection system may be considered out of service. See Data Sheet 10-7 for examples of fire protection systems discovered to be out of service through ITM.

2.4 Fire Protection System Inspection, Test, and Maintenance Frequencies

2.4.1 General

Sections 2.4 through 2.12 contain recommendations for the scope and frequency of fire protection system ITM activities. Some of these activities may be modified based on positive or negative factors present at the facility. Clients of FM Global can discuss modifying ITM activities with an FM Global field engineer.

2.4.2 Fire Protection Control Valves in Automatic and Manual Fire Protection Systems

2.4.2.1 Perform control valve inspection and test activities for automatic and manual fire protection systems in accordance with Table 1.

Table 1. Control Valves in Automatic and Manual Fire Protection Systems

ID ITM Activity & Scope Frequency Details 1a Visually inspect icontrol valves for full-open, secured, and accessible conditions.

Weekly Record visual inspection results on a form listing all control valves and their locations and areas. See Appendix D for a sample form.

1b Inspect control valves installed in waterflow alarm sensing lines when the alarm actuates process or building interlocks for full-open and locked conditions.

1c Visually inspect enhanced security indicating control valves for full-open, secured, and accessible conditions.

Semiannually Record visual inspection results on a form listing all control valves and their locations and areas. See Appendix D for a sample form.

2 Physically test control valves for full-open position.This includes post-indicating valves (PIV); wall-mounted post-indicating valves (WPIV); non-FM Approved indicating-butterfly valves (IBV); non-rising stem (NRS) valves;

curb-box/road-way (CB/RW) valves; and non-indicating butterfly valves.

Monthly Record physical inspection results on a form listing all control valves and their locations and areas. See Appendix D for a sample form.

3 Test control valve supervisory alarms and enhanced security control valves (e.g., tamper switches).

Semiannually

4 Full-travel exercise all control valves recording number of turns-to-close and turns-to-reopen.

Annually

2.4.2.3 Secure control valves using the following methods. Note that a control valve is considered secured when the valve operator is prevented from being manipulated more than one turn toward the closed position, or at all for quarter-turn valves (e.g., ball valves).

A. Secure each control valve separately with a dedicated lock and chain. Secure control valves with a sturdy, key-operated lock and chain capable of withstanding breakage except by heavy-duty bolt cutters or similar hand tools. Do not use combination locks. Do not use seals or breakaway locks except when valves are 1.5 in. (38 mm) nominal diameter or smaller, or control five or fewer sprinklers. Treat valves in the waterflow alarm sensing lines actuating process and building interlocks as control valves in automatic fire protection systems.

B. For a wall-mounted post-indicating valve, ensure the valve hand-wheel cannot be removed from the valve stem when the valve is secured.

C. For a curb-box/road-way valve, secure all operating wrenches with a sturdy lock and chain, and inspect valve sleeve for cover.

2.4.2.4 Limit the distribution of control valve keys to only individuals responsible for fire protection system ITM, and local management.

Fire Protection System Inspection 2-81 FM Global Property Loss Prevention Data Sheets Page 5

2.4.2.5 Ensure control valves remain accessible in case of an emergency. Additionally, verify the appropriate signage is in place to identify the control valve and, where necessary, signage is in place to quickly locate control valves not readily visible.

2.5 Automatic Sprinkler Systems

2.5.1 All Sprinkler Systems

2.5.1.1 Conduct the ITM activities recommended in Table 2a for all types of sprinkler systems (wet, dry, preaction, deluge, fixed water spray, antifreeze, and refrigerated area).

Table 2a. ITM Activities Applicable to All Types of Sprinkler Systems

ID Recommendation Frequency Details 1 Inspect, test, and exercise control valves in automatic fire protection systems.

Per Table 1 Per Table 1

2 Test waterflow alarms (including flow switches) by flowing water through a system test connection.

Quarterly (Annually for antifreeze systems)

Verify the following:

- Local notification devices (e.g., bell, horn, and/or strobe) activate.

- Alarms register on remote fire alarm control panels in constantly attended locations or at central alarm monitoring stations.

3 Test building and/or process interlocks actuated by waterflow alarms to verify the desired system actions are initiated and achieved.

Annually

4 Flow test from system main-drain to check for significant obstructions in the water supply upstream of each system riser.

Annually If multiple system risers are manifolded together and supplied by a common lead-in, then one main-drain test will sufficiently evaluate the water supply available to all system risers fed from the manifold.

Ideally, main-drain testing is completed after annual control valve exercising, as main-drain testing is often the final step in restoring system impairments such as valve closures.

5 Investigate systems for obstructive debris. When obstructions suspected

See 2.5.1.2.

6 Conduct a complete system flushing.

Physically remove obstructive deposits or replace piping.

When obstructions discovered (debris)

See 2.5.1.2.

7 Inspect system sprinklers, nozzles, piping, pipe support, and seismic protection for damage and/or other poor conditions.

Annually or more frequently based on the operating environment or facility experience.

2.5.1.2.6 During ITM activities or pipe alterations, if deposits (tubercles) are found attached to internal pipe walls, physically remove the deposits or replace the affected sections of pipe. Additionally, refer to Data Sheet 2-1, Corrosion in Automatic Sprinkler Systems, and develop a solution to suppress the existing corrosion mechanism and prevent the tubercles from reforming.

2.5.1.3 Inspect sprinkler system components for damage and/or other poor conditions.

2.5.1.3.1 Conduct a close examination of sprinklers and nozzles to look for damage, including any of the following:

A. Leakage from the orifice button and seal as shown by green discoloration or white deposits.

B. Surface corrosion when exposed in or near atmospheres containing high humidity and temperature, caustic or acidic vapor, solvent vapor, or other corrosive agents.

C. Surface accumulations, including residue or dust.

D. Paint when not properly protected during painting operations, whether occurring at floor or ceiling level.

E. Exposure to temperatures within 50°F (28°C) of their temperature rating (e.g., located above ceiling-level heating equipment or near heated process equipment).

F. Indications of freeze damage, including reduced link tension, metal gaskets forced upward, bent hook pieces, tilted glass or metal buttons, badly dished or distorted diaphragms, or bent struts.

G. Mechanical impact shown by distorted deflector or frame.

H. Sealed concealed sprinklers that have been adhered to the ceiling.

I. Damage to any protective devices (e.g., concealed cover plates, cages, plastic bags) or factory-applied coatings.

2.5.1.3.2 Inspect piping, pipe supports, and seismic protection for physical damage or poor conditions, including the following: bent piping (e.g., from mechanical impact); leaking fittings or piping due to corrosion;

missing, detached, corroded, or broken pipe hanger or seismic brace assemblies; and piping used to support wiring or other materials.

2.5.1.3.3 Tailor inspection frequency and scope based on facility experience (inspection results and/or past instances of sprinkler leakage), and consider if measures have been taken to reduce the susceptibility to sprinkler damage (wax-coatings or corrosion-resistant construction).

Fire Protection System Inspection 2-81 FM Global Property Loss Prevention Data Sheets Page 7

2.5.1.3.4 Complete piping inspections from floor level unless large sections of piping are obstructed from view or difficult to see (e.g., within combustible concealed spaces, automated storage retrieval systems or buildings with tall roofs).

2.5.1.3.5 If damage is discovered during inspections, perform the following:

A. Test a random sample of sprinklers or replace sprinklers in accordance with Data Sheet 2-0.

B. Test a random sample of nozzles or replace nozzles in accordance with Data Sheet 4-2.

C. Protect sprinklers/nozzles, or control the environmental conditions that caused the damage, in accordance with Data Sheets 2-0 and/or 4-2.

2.5.1.3.6 Increase the inspection frequency (from annually) when sprinklers/nozzles are exposed to harsh environmental conditions (corrosives, dirt, dust, oil) or prone to impact.

Examples of harsh environmental conditions include process equipment containing elevated temperatures and high humidity; caustic or acidic vapor, solvent vapor (e.g., dryers/ovens, oil cookers, paint-spray tunnels);

and exhaust ventilation systems conveying particulates or gases/vapor.

Examples of locations where sprinklers/nozzles are prone to impact include in-rack sprinklers within warehouse racking and sprinklers positioned close to conveyor systems.
