HEALTH WARNINGS

Halon 1211, when applied to fire or to heated surfaces above 900 °F (482 °C), can produce toxic by-products. These by-productsresulting from the decomposition of Halon 1211 have a sharp irri-tating odor. The by-products are principally halogen acids, free halo-gens and carbonyl halides. These decomposition by-products, evenin low concentrations, are dangerous and in sufficient concentra-tions may result in personal injury or death. The quantity of theseby-products that may be generated depends on the size of the fire,the concentration of Halon 1211, and the length of time the halon isin contact with the fire or heated surface. If these irritating odors aredetected, evacuate the area immediately.

In addition, inhalation of concentrations of the Halon 1211 agentitself of three to four percent by volume for one minute may causedizziness and tingling of the extremities. At concentrations of four tofive percent by volume, effects such as dizziness, impaired coordi-nation and reduced mental acuity become more definite with expo-sure of from one to two minutes duration. At concentrations ofgreater than five percent, in addition to the above symptoms, thereis a risk of unconsciousness and possible death if the exposure isprolonged. It is difficult for the human senses to detect the presenceof Halon 1211 or the concentration level, since Halon 1211 is a col-orless gas with a very faint odor. The effects of exposure to Halon1211 should disappear quickly upon removal from exposure.

Avoid inhalation of toxic by-products or concentrations of halon1211 by evacuating and ventilating the area. Where Halon 1211 hasbeen released in a confined space, prohibit smoking and use ofelectric and gas heaters and furnaces in the immediate area untilthe space has been completely ventilated.

Do not use the Halon 1211 extinguisher in confined spaces lessthan the applicable volume per extinguisher indicated below. If partof the confined space is occupied by equipment or other objects,this should be taken into account when calculating volume. The fol-lowing calculations are based on a concentration of 2% of Halon1211.

For further information, refer to Ansul Technical Bulletin No. 47.

In the event a person is overexposed to the agent, or exposed totoxic by-products, the person must be removed from exposure andgiven fresh air; summon medical assistance immediately.

! WARNING

FE-36 may decompose when applied to a fire or to a heated sur-face above 900 °F (482 °C). The product of this decomposition isgaseous hydrogen fluoride. Hydrogen fluoride has an irritating odor.This decomposition product, even in low concentration is danger-ous and in sufficient concentration may cause injury or death. Thequantity of by-product that may be generated is dependent upon firesize, agent concentration, and the length of time FE-36 is in contactwith the fire or heated surface. If this irritating odor is detected,evacuate the area immediately.

Avoid unnecessary inhalation of toxic by-products or concentrationsof FE-36 by evacuating and ventilating the area. Where FE-36 hasbeen released in a confined space, prohibit smoking and use ofelectric and gas heaters and furnaces in the immediate area untilthe space has been completely ventilated.

Toxicity tests on FE-36 have demonstrated no remarkable clinicalsigns in 90-day inhalation studies. All genotoxicity tests were nega-tive and cardiac sensitization studies have shown favorable results.The NOAEL is 10% and the LOAEL is 15%. General safety prac-tices should be followed when using FE-36. Avoid unnecessarycontact. If inhaled, immediately remove to fresh air. Remain calm.For skin contact, flush area with lukewarm water. Do not use hotwater. If frostbite has occurred call a physician. In case of eye con-tact, immediately flush eyes with plenty of water for at least 15 min-utes. Call a physician.

FE-36 extinguishers should not be used in confined spaces lessthan the applicable volume per extinguisher listed below. If part ofthe confined space is occupied by equipment or other objects, thisshould be taken into account when calculating volume. The follow-ing calculations are based upon the FE-36 LOAEL of 15%.

TABLE OF CONTENTS

FOREWORDThe Occupational Safety and Health Administration (OSHA) – Rulesand Regulations state that ‘‘the National Fire Protection Association(NFPA) provides excellent guidelines in its standard for portable fireextinguishers.’’ NFPA Pamphlet 10 – ‘‘Portable Fire Extinguishers’’ isavailable from the National Fire Protection Association, BatterymarchPark, Quincy, MA 02269.

RESPONSIBILITYThe owner or occupant of a property in which fire extinguishers arelocated has an obligation for the care and use of these extinguishers atall times. By doing so, he/she is contributing to the protection of life andproperty. The nameplates and instruction manual should be read andthoroughly understood by all persons who may be expected to usethese extinguishers.

RECHARGEAll extinguishers shall be recharged immediately after use. They shallalso be recharged when dictated by an inspection or when performingmaintenance. Recharge is the replacement or replenishment of theextinguishing agent. It also includes the replenishment of the expellantfor certain types of extinguishers. When performing the recharge, useonly those materials specified on the nameplate. The use of otherrecharging materials may impair the efficiency, cause malfunction, ordamage the extinguisher resulting in possible injury to the operator.

INSPECTION‘‘Inspection’’ is a ‘‘quick check’’ that an extinguisher is available and willoperate. It is intended to give reasonable assurance that the extin-guisher is fully charged and operable. This is done by seeing that it isin its designated place, that it has not been actuated or tampered with,and that there is no obvious physical damage or condition to preventoperation. The value of an inspection lies in the frequency, regularity,and thoroughness with which it is conducted. Extinguishers shall beinspected at regular monthly intervals, or at more frequent intervalswhen circumstances require.

MAINTENANCEExtinguishers shall be maintained at regular intervals, not more thanone year apart, or when specifically indicated by an inspection.Maintenance is a ‘‘thorough check’’ of the extinguisher. It is intended togive maximum assurance that an extinguisher will operate effectivelyand safely. It includes a thorough examination and any necessaryrepair, recharging, or replacement. It will normally reveal if there is aneed for hydrostatic testing of an extinguisher.

Extinguishers removed for maintenance or recharge shall be replacedby spare extinguishers of the same type and at least equal rating.

Halon 1211 has been classified under the Montreal Protocol as anozone depleting chemical. Its release into the atmosphere for any rea-son other than fire extinguishment MUST be minimized. For this rea-son, an appropriate Halon recovery system should be used when dis-charging Halon for servicing.

SIX YEAR TEARDOWNRefer to NFPA 10, “Portable Fire Extinguishers” for detailed instructionsconcerning six-year teardown.

NOTICEAt the six year teardown, SENTRY Halon 1211and CLEANGUARD (FE-36) extinguishersrequire replacement of the valve stem assem-bly and valve body quad ring. Lightly lubricatenew valve stem O-ring and valve body quadring with Silicone Grease (Part No. 9030). Donot lubricate valve stem seat.

HYDROTESTExtinguishers shall be hydrostatically tested at regular intervals asrequired in the NFPA Pamphlet 10 – ‘‘Portable Fire Extinguishers,’’ ormore frequently when inspection or maintenance indicates a specificneed. Such tests are required on extinguisher shells.

IF, AT ANY TIME, AN EXTINGUISHER SHOWS EVIDENCE OF COR-ROSION OR MECHANICAL DAMAGE, IT SHALL BE SUBJECTEDTO A HYDROSTATIC PRESSURE TEST, OR REPLACED.

THE EXTINGUISHER SHALL BE DISCHARGED AND HYDROTEST-ED AT TWELVE YEAR INTERVALS IN ACCORDANCE WITH THEAPPROPRIATE PROCEDURES. The periodic hydrostatic retest maybe conducted within twelve months of the specified interval. Refer toAnsul Portable and Wheeled Fire Extinguisher Hydrostatic TestInstructions, Form No. F-7602.

RECORD KEEPINGEach extinguisher shall have a tag or label securely attached that indi-cates the month and year the maintenance was performed and shallidentify the person performing the service. The same record tag or labelshall indicate if recharging was also performed. The tag shall not beplaced on the front of the extinguisher where it could obscure operat-ing instructions. At least monthly, the date the inspection was per-formed and the initials of the person performing the inspection shall berecorded.

A separate label shall also be affixed to the extinguisher following asuccessful hydrostatic test. This label shall include the month and yearthe test was performed, the test pressure used, and the name or initialsof the person performing the test. This label shall be self-destructivewhen removal from the extinguisher is attempted, and shall not beplaced on the front of the extinguisher where it could obscure operat-ing instructions.

In addition to the required tags or labels, a permanent file record shouldbe kept for each extinguisher. This file record should include the dateand the name of the person and/or agency performing maintenance,recharge or hydrostatic test. A description of dents remaining afterpassing a hydrostatic test should also be noted in this record.

Parts of above were taken from NFPA Pamphlet 10.

INTRODUCTION

Examine interior of agent tank for pitting or corrosion. If found, itindicates that excessive moisture has been introduced into theshell. Mark shell ‘‘REJECTED’’ and return to owner without recharg-ing. Shell is to be properly destroyed to prevent reuse.

! CAUTION

Air or gas should not be used for pressure testing as failure of theshell could be violent and dangerous.

! WARNING

To Operate The Extinguisher:1. Remove the extinguisher from its station.

2. Use the handle to carry the extinguisher to the fire. Walk at a rapidpace. DO NOT RUN.

3. Pull the ring pin and remove the hose from its holder (if soequipped).

4. Proceed to the upwind side of the fire. Stay well clear of theflames. From this position, the air currents help carry the agentinto the fire. It also assures maximum visibility and provides pro-tection from the heat.

5. Position yourself at the distance recommended on the extin-guisher nameplate, and squeeze the operating lever to the fullopen position. Direct the extinguishing agent at the base of the firewith a sweeping motion, covering the full width of the fire. Do notrelease the operating lever until the fire is completely extin-guished.

NFPA 10, 1988 Edition, 4-3.1: Extinguishers shall be inspected wheninitially placed in service and thereafter at approximately 30-day inter-vals. Extinguishers shall be inspected at more frequent intervals whencircumstances require.

NOTICEBecome familiar with the Service and Repairsection prior to performing Inspection.

To inspect the dry chemical, Halon 1211 and CLEANGUARD extinguisher:

1. Make certain the extinguisher is in its designated place, is clearlyvisible and is accessible for immediate use. Any obstructions thatobscure it, or that would otherwise impair its being readily acces-sible, should be removed.

2. Check service date to determine need for inspection or mainte-nance.

3. Check that pointer on extinguisher pressure gauge is in the oper-ating range. (Upper and lower point of operating range normallyreflects the operating temperature range of the extinguisher.)

NOTICEThe operating pressure of the Halon 1211 andCLEANGUARD extinguisher varies with tem-perature. A Halon 1211 and CLEANGUARDstored pressure extinguisher shall berecharged if a loss in pressure occurs, adjust-ed for temperature, exceeding 10% of thecharging pressure. If a pressure loss is sus-pected, condition the extinguisher at 70 °F (21 °C) for 12 hours and then recheck the pres-sure reading. If gauge still shows a 10% pres-sure loss, the extinguisher must be recharged.

4. Remove the extinguisher from its wall hanger or bracket. Checkthat the hanger or bracket is secure enough to hold the extin-guisher safely.

5. Heft (lift up and down slightly) the extinguisher to determine if it ischarged with agent. When hefting a Halon 1211 or CLEANGUARD extinguisher, also shake it side to side and listenfor any rattles. Internal rattling indicates a loose or broken pick-uptube and the extinguisher must be removed from service, dis-charged, repaired and recharged before returning to service.

6. Examine the extinguisher shell and all external parts for evidenceof physical damage, corrosion or other impairments.

NFPA 10, 1988 Edition, 4-1.4: Maintenance, servicing and rechargingshall be performed by trained persons having available the appropriateservicing manuals, the proper types of tools, recharge materials, lubri-cants and manufacturers recommended replacement parts.

NOTICEAlways be alert for any indications of damageor inoperability in the unit. No manual cananticipate everything that could happen to aunit. In the event that something not covered inthe manual is found, ascertain whether anypotential for damage exists and repair orreplace, as necessary. See Service and RepairSection, Page 24.

To maintain the dry chemical, Halon 1211 and CLEANGUARDextinguishers:

1. Make certain the extinguisher is in its designated place, is clearlyvisible and is accessible for immediate use. Any obstructions thatobscure it, or that would otherwise impair its being readily acces-sible, should be removed.

2. Check service date to determine need for inspection or mainte-nance.

3. Check that pointer on extinguisher pressure gauge is in the oper-ating range. (Upper and lower point of operating range normallyreflects the operating temperature range of the extinguisher.)Ensure the gauge is the proper model for the extinguisher beingmaintained. Also check the gauge for mechanical damage. (Forgauge replacement, see Service and Repair Section, Page 24.)

NOTICEThe operating pressure of the Halon 1211 andCLEANGUARD extinguisher varies with tem-perature. A Halon 1211 and CLEANGUARDstored pressure extinguisher shall berecharged if a loss in pressure occurs, adjust-ed for temperature, exceeding 10% of thecharging pressure. If a pressure loss is sus-pected, condition the extinguisher at 70 °F (21 °C) for 12 hours and then recheck the pres-sure reading. If gauge still shows a 10% pres-sure loss, the extinguisher must be recharged.

4. Remove the extinguisher from its wall hanger or bracket. Checkthat the hanger or bracket is secure enough to hold the extin-guisher safely.

5. Weigh the extinguisher. Extinguisher weight MUST fall within thetotal charged weight limits as printed on the nameplate. Any extin-guisher not meeting those limits MUST be properly recharged.

6. Check the date of manufacture stamped on the shell or the dateof last hydrostatic test on the label affixed to the extinguisher tomake certain it does not exceed the test interval of twelve yearsas specified in the current edition of NFPA Pamphlet 10 and AnsulTechnical Bulletin Number 50.

NOTICEDate stamp locations are: top collar, bottomskirt, or (after 1990) bottom dome of shell.These painted surfaces may require closeexamination to distinguish date.

7. Examine the extinguisher shell and all external parts for evidenceof burns, physical damage, corrosion or other impairments.Depending on the degree of corrosion or extent of mechanicaldamage, the extinguisher may constitute a potential hazard topersons in its vicinity, to operators or service personnel; and mayrequire replacement or hydrostatic test.

NOTICEWelding, soldering or brazing repairs to theextinguisher are not permissible.

8. Check the visual inspection seal on metal ring pin models. Checkthat barb is intact on plastic pull pin models.

9. Older model extinguishers have a window (as shown) in the valveassembly. A metal tab should extend through that window. Thetab restricts operating movement to protect the valve stem. If thetab is bent or missing, visually inspect the valve stem by lifting theoperating lever. Refer to the Maintenance section for repair orreplacement procedures.

10. Check that the valve stem is in the full up position and that thestem has approximately 1/16 in. clearance.

NOTICEAt the six year teardown, SENTRY Halon 1211and CLEANGUARD extinguishers requirereplacement of the valve stem assembly andvalve body quad ring. Lightly lubricate newvalve stem O-ring and valve body quad ringwith Silicone Grease (Part No. 9030). Do notlubricate valve stem seat.

11. Check the nameplate for damage and readability. If operatinginstructions are not legible, an instructed (but not necessarilytrained) person may not recall extinguisher operation in theexcitement caused by a fire.

12. Remove hose and inspect hose and nozzle for obstructions, cuts,cracks or other mechanical damage. Insects are a commoncause of obstruction, particularly in warmer climates.

GAUGE REPLACEMENT PROCEDURES1. Invert the extinguisher and press the lever to release all pressure.

(For Halon 1211 and CLEANGUARD models, Reclaim accordingto procedures on Page 18 of Appendix.) Remove valve assembly.

2. Disassemble the valve assembly, removing the pick-up tube,valve stem, and spring.

3. Remove damaged/defective gauge. If gauge is difficult to remove,immerse in hot water to loosen sealant.

4. Clean the gauge port threads. Use 1/8–27 NPT pipe tap to chasethreads, if necessary. Be careful not to tap too deep as gauge willnot tighten properly and valve assembly will have to be replaced.Be sure to select proper replacement gauge for the model extin-guisher being repaired.

5. Apply plastic lead pipe sealant (ARMSTRONG C-4 w/Activator Wor equivalent) to the threads of the new gauge. Be careful not toget any sealant into the hole in the face of the gauge socket. Ansuldoes not recommend the use of pipe tape.

6. Screw the new gauge into the valve body making certain that theoperating range on the gauge face is pointed to the top of thevalve.

7. Clean valve body, lubricate, and reassemble. Recharge extin-guisher and check for leakage (use LEAK-TEC FORMULA 177 orequivalent). If there is leakage through gauge threads, relievepressure from extinguisher and tighten gauge one more turn. Ifleakage cannot be stopped, discard valve assembly.

BRACKETS

Introduction

Brackets are available for each Ansul SENTRY hand portable extin-guisher. Certain applications require extinguishers to be mounted inbrackets for safety and restraint.

Installation and Mounting

Make certain mounting location and position meet NFPA-10 require-ments.

Brackets may be mounted in a vertical, horizontal or sloping position onsufficiently strong, stationary supporting surfaces or within suitablevehicle compartments.

The brackets are provided with mounting holes in the back plate(frame) and /or mounting holes in the base. The mounting surface willusually dictate that either the back or the base of the bracket be usedbut in some cases, both may be used to improve the weight distribu-tion. Use good quality fasteners, one in each mounting hole. Fastenersshould be tightened as recommended for the specific type and gradeof fastener used.

Even though welding is an effective method of securing the bracket inplace, it is NOT recommended because Ansul has no control over theplacement and quality of the welds.

Mounting Location

Two considerations will affect the choice of bracket mounting location.

The first is fire protection needs.

1. The extinguisher must be visible, not hidden in an out-of-the-wayspot.

2. The extinguisher must be easy to reach.

3. The extinguisher should not be placed where a fire is likely tomake it inaccessible.

The second set of considerations deal with keeping the extinguishersafe and secure.

1. Avoid locations where grease or oil could build up on the extin-guisher and bracket.

2. Select a relatively flat mounting surface which is strong enough tosupport the weight of the extinguisher and bracket.

3. Avoid surfaces which may flex enough to cause metal fatigue inthe bracket support.

4. Be sure there is enough space to allow proper mounting of thebracket and easy access to the extinguisher.

5. Avoid locations that may expose the extinguisher to temperaturesdetrimental to its operation (such as too near a motor or exhaustmanifold).

20

APPENDIX

BRACKETS (Continued)

Inspection

Inspection of the bracket should be performed whenever extinguisherinspection is performed.

1. Check for looseness between the extinguisher and the bracket.The band clamp should shut tightly, compressing the band grommet.

2. Inspect the extinguisher and bracket for wear caused by move-ment of the extinguisher within the bracket.

3. Examine the entire bracket closely for loose or worn hinges orhingepins, bent or cracked bands and worn or missing grommets.Avoid future damage by replacing or repairing all components thatare missing, worn or damaged.

Maintenance

Maintenance is a very important factor in the lifespan and reliability ofa bracket. Bracket maintenance should be performed whenever extin-guisher maintenance is performed.

1. Clean any dirt or other foreign material from the extinguisher andbracket using a brush, cleaning cloth or soap and water.

2. Remove the extinguisher from the bracket and clean extinguishersurfaces which were in contact with the bracket.

3. Inspect the bracket. If it is bent or cracked, replace it.

4. Check to see that the bracket is firmly mounted. Tighten orreplace mounting fasteners.

5. Avoid possible rust damage by cleaning and painting wheneverbare metal is exposed.

6. Following extinguisher maintenance, secure the extinguisher inthe bracket. If the bracket does not hold the extinguisher secure-ly or the bracket is difficult to close, replace the affected partand/or the entire bracket.

Nozzle Wrong nozzle Replace with proper model nozzle recommended by Ansul. Refer to Parts List.

Nozzle body corroded, cracked or dented Replace nozzle.

Threads nicked, worn or cross-threaded Replace nozzle.

* The term caked, as applied to dry chemical describes a specific condition that is best identified as dry chemical containing hard lumps. These lumps will render a dry chemical extinguisher inopera-tive. The condition usually follows the absorption and later the evaporation of an unusual amount of moisture. It is often confused with ‘‘packing’’ (a condition produced by normal settling, by vibrationor impact). A simple procedure to determine which condition exists is the UL test in which lumps are dropped from 4 in. (10 cm) onto a clean, hard surface. If the lumps do not break up into individ-ual particles, caking is present. For additional details, refer to Ansul Technical Bulletin No. 45 ‘‘Caking Versus Packing of Dry Chemical Agents’’ (Form No. F-8083).

** Replacement maintenance nameplates from Ansul will not have a UL manifest.
