I. Purpose and Introduction This emergency action plan has been developed for the University of New Hampshire’s (UNH) Whittemore Center Arena to comply with Occupational Safety and Health Administration (OSHA) standard 29 CFR 1910.38 for potential emergency situations related to the anhydrous ammonia refrigeration system. This plan does not apply to small leaks and mishaps which can be successfully covered under the facility’s hazard communication program required by 29 CFR 1910.1200. The key points of UNH’s hazard communication response are that partial or total evacuation is not necessary and employees in the immediate work area of the release or mishap can safely handle the situation. The purpose of this emergency action plan is to provide information to the employees and establish employee actions for the response to an accidental release of anhydrous ammonia at the Whittemore Center that is beyond UNH’s capabilities under its hazard communication program. OSHA standard 29 CFR 1910.120(q) (emergency response program to hazardous substance release) does not apply per 1910.120(q)(1) since UNH will evacuate their employees from the danger area when an emergency occurs and will rely on an outside party to provide emergency response.

UNH will review this plan annually in conjunction with the annual employee training and will update it as necessary.

The Whittemore Center Arena maintains a closed loop anhydrous ammonia refrigeration system for year round ice rink temperature control. Ammonia is a widely used refrigerant because it can be liquefied easily by compression or cooling, and when returned to its gaseous state can absorb large amounts of heat. The Whittemore’s system consists of three compressors (two in operation and one for back-up), an exterior holding tank for the liquid phase, an internal holding tank where the ammonia transitions from liquid to gas and a cooling tower above the exterior tank. The exterior tank and cooling tower are located directly outside the compressor room. The exterior tank holds a maximum of 1,000 pounds of anhydrous ammonia. Return and supply pipes connect the exterior equipment to the compressors. The compressors, internal tank and piping are located in the compressor room. The system is an indirect heat transfer system where the energy from the refrigeration process is transferred to a brine solution which is circulated in the piping underneath the ice rink. Therefore, ammonia is limited to the compressor room and exterior storage tank adjacent to the cooling tower.



II. Hazard Evaluation Anhydrous ammonia is a clear, colorless gas with a pungent, irritating odor. Anhydrous means without water. Refrigerant grade anhydrous ammonia is at least 99.95% pure ammonia. Ammonia is extremely soluble in water. Anhydrous ammonia boils at a temperature of -28° F. Liquid anhydrous ammonia is stored in tanks under pressure. When the pressure is released, the liquid evaporates rapidly, generally forming an invisible vapor or gas. The rapid evaporation causes the temperature of the liquid to drop until it reaches the normal boiling point of -28° F. Liquid and gas ammonia expand and contract with changes in pressure and temperature. Anhydrous ammonia is considerably lighter than air and will rise in dry air. However, due to ammonia’s affinity for water, it can react with the humidity in the air and may remain close to the ground and form a dense, visible white cloud. The safety data sheet (SDS) for anhydrous ammonia, included in Attachment A, is maintained on file in the operations office (arena staff), compressor room and the fire command station. These areas are identified on the site plan contained in Attachment B. Detection level: According to OSHA, ammonia has an odor detection threshold of 5 to 50 ppm. The pungent and distinctive odor of the vapor, even at low concentrations provides adequate warning so that no person will voluntarily remain in concentrations which are hazardous. Exposure Limits: The OSHA regulations establish a permissible exposure limit (PEL) of 50 parts per million (ppm) as an 8-hour time weighted average (TWA). The National Institute of Occupational Safety and Health (NIOSH) have recommended airborne exposure limits of 25 ppm as a 10-hour TWA and 35 ppm not to be exceeded during any 15 minute period. The American Conference of Industrial Hygienists (ACGIH) has established threshold limit values of 25 ppm (8-hour TWA) and 35 ppm for short term exposure. The OSHA limit is a regulatory limit and the NIOSH and ACGIH limits are recommended levels. Flammability: Ammonia is classified by the U.S. Department of Transportation as a nonflammable gas. First Aid: As a result of its affinity for water, ammonia gas can be irritating to the eyes, throat and breathing passages. Ammonia in either the vapor or liquid state primarily affects the eyes, lungs and skin. Accordingly, the best means of providing first aid for an injury caused by ammonia contact with the eyes or skin is to flush immediately with clean water. Remove contaminated clothing, but only after flushing with water to prevent skin from sticking to clothing. Promptness in initiating treatment, using adequate quantities of water and continuing its application for at least fifteen minutes or longer if necessary, are all essential in successful first aid management of an eye or skin injury resulting from contact with ammonia. Immediate medical attention should also be obtained. In the event of inhalation, the exposed individual should be taken to a clean uncontaminated area. For severe exposure to high concentrations, the individual should receive immediate medical attention.



There are two first aid kits located in the Whittemore Center’s operations office; one is portable and the second is permanent. There are two automated external defibrillator (AED) machines located at the loading dock and in the concourse. An eye wash and emergency shower are located at the loading dock. The eye wash is checked weekly for proper water flow. The loading dock, concourse, eye wash and shower are identified on the attached site plan (Attachment B). All full time arena personnel are trained in basic first aid including cardiopulmonary resuscitation (CPR) and operation of the AED machines. III. Emergency Alarm Systems There are two ammonia sensors mounted 8-10 feet high on a centrally located pillar in the compressor room. One sensor is continuously monitoring the concentration of ammonia in the room. The second sensor is for back-up purposes in the event that the primary sensor malfunctions. Both sensors serve as primary and back-up sensors and their designation is on a pre-set schedule. The sensors are maintained by UNH Facilities and are tested and calibrated once every six months based on manufacturer’s recommendations and industry standards. The controllers for the monitoring system are located in the safety corridor behind the compressor room. The system includes a remote digital readout (safety corridor) of the compressor room ammonia concentration in ppm. A remote digital readout is also located in the fire command station at the bottom level of the glass block tower at the opposite side of the Whittemore Center. The ammonia detection system has two alarm set points which function as follows: Alarm 1: Alarm 1 is activated when the airborne ammonia concentration in the

compressor room reaches 35 ppm. Blinking yellow lights are activated directly outside of the compressor room both inside and outside of the Whittemore Center. These lights notify arena staff and persons inside and outside the Whittemore Center that there is an elevated level of ammonia in the compressor room. Ventilation fans automatically start when the compressor room concentration equals or exceeds 35 ppm. The ventilation fans are independent of the HVAC system for the building. The HVAC system is automatically shut down when the alarm is activated. The alarm is sent to UNH dispatch who notifies Whittemore Center employees and UNH Facilities refrigeration staff. Emergency Contacts are listed in Section IX.

Alarm 2: Alarm 2 is activated when the airborne ammonia concentration in the

compressor room reaches 100 ppm. Blinking white lights are activated outside of the compressor room adjacent to the yellow lights. The HVAC system is automatically shutdown when the alarm is activated. The alarm is sent to the UNH Dispatch who contacts the Durham Fire Department. An emergency evacuation is initiated.

IV. Emergency Shutdown System The ammonia refrigeration system is equipped with multiple emergency shutdown switches that are manually triggered to lock out all compressors and close the liquid line solenoid valve coming



from the receiver located under the cooling tower. Attachment C depicts the following five emergency shutdown switches at the following locations:

• Inside the safety corridor behind the compressor room • Inside the fire command station (key activated) • Inside the operations office (rink level) • On the main compressor control panel in the compressor room • Under the cooling tower

The following personnel are authorized or may designate someone to shut down the ammonia system for a low level alarm (35 ppm) or in the event that ammonia is detected by personnel and it is believed that the sensors are not operating properly (Emergency Contact information may be found in Section IX):

• Assistant Director, Campus Recreation • Senior Facilities Manager • Refrigeration Engineers • Third Party Professional Refrigeration Company • Durham Fire Department • Whittemore Center Operations Staff

If levels exceed 100 ppm, indicated by Alarm 2-blinking white light, any individual may shut down the system. If the alarm system malfunctions at any time, UNH Facilities staff will take hourly readings from the remote readout in the safety corridor outside the compressor room and log results of the ammonia concentration in the compressor room until the system resumes normal operation. V. Emergency Response and Notification Compressor Room If an emergency situation (alarm 2 has been triggered and ammonia level in the compressor room equals or exceeds 100 ppm) occurs, employees will evacuate and an outside party will be immediately summoned for emergency response to an ammonia release. A response agreement has been entered into with the Durham Fire Department and will be reviewed annually. A signed copy of the agreement letter is contained in Attachment D. In addition, UNH is in partnership with multiple professional refrigeration companies for mitigation, response and recovery during an ammonia emergency. If an employee detects an odor of ammonia, they should activate the exhaust fans and report the odor to the operations manager or their supervisor. Upon activation of Alarm 1 (35 ppm), the UNH dispatch is alerted and will contact one of the Refrigeration Engineers immediately to check on the status of the alarm. All employees in the Whittemore Center will be notified of the activation of Alarm 1. Upon activation of Alarm 2 (100 ppm), the UNH Dispatch is alerted and the dispatcher will notify the Durham Fire Department and send out a refrigeration engineer to



check the status of the alarm. UNH management staff will also be notified by Dispatch as soon as possible after the response has been initiated. Dispatch will notify the UNH Police Department who will be responsible for making any required notifications to outside emergency management, regulatory agencies, and university officials as necessary. A representative from the Durham Fire Department will be the On-Scene Commander upon arrival on site. When Alarm 2 is activated an emergency evacuation is initiated. In the event of an evacuation, UNH employees and the general public are notified through the public address system or the fire alarms. Exterior Tank The exterior anhydrous ammonia tank (liquid phase) is inspected daily by UNH Facilities staff for leaks or malfunctions. If an inspection reveals that a problem exists, the Assistant Director of Campus Recreation or Facilities Manager is notified and the standard operating procedures for release response contained in Attachment E are followed which includes an immediate shutdown of the HVAC system. VI. Emergency Evacuation and Accountability Attachment D contains evacuation routes to follow in the event of an emergency requiring evacuation of the Whittemore Center or part thereof. Emergency evacuation routes are posted throughout the Whittemore Center. If an evacuation is necessary during a large public event, the Assistant Director of Campus Recreation or on-scene commander will determine the safest place to evacuate to based on wind direction and location of the release. To identify wind condition, there is a wind sock mounted on top of a parking lot light. This light is on the back side of the Woodsides parking lot facing the Whittemore Center which is clearly visible from the loading dock ramp and from outside the fire command station. If there’s a small public event or no public event, employees and other people in the building will evacuate to the main lobby (form of shelter in place). The main lobby is the part of the Whittemore Center farthest from the compressor room. If it is necessary to leave the building, further instructions will be provided from the on-scene commander or his/her designee. If an event is in progress, the public address system will be used to notify patrons of evacuation plans. After UNH staff assist with the evacuation of non-UNH employees (i.e. sport spectators, students, etc.), they will meet at New Hampshire Hall for accountability. The head arena staff person on duty and the event coordinator (if a large public event was in progress) assume the responsibility to account for all employees on duty during the emergency release. Detailed evacuation procedures are contained in the Whittemore Center Arena Emergency Response Plan which is emergency plan for any emergency at the Arena.



VII. Employee Training and Exercises All UNH employees involved in the operation and maintenance of the ammonia refrigeration system or with an emergency response associated with the refrigeration system are trained in emergency evacuation and assisting others in evacuating. Employees are trained initially, annually and any time the plan is changed. In addition, employees with any involvement with the ammonia refrigeration system are provided hazard awareness training in accordance with 29 CFR 1910.1200(h). Training includes information on the physical and health hazards of ammonia, methods for detecting an ammonia release, measures to take to protect individuals from exposure, information on the design of the system and where potential releases may occur. VIII. Regulatory Notifications In the event of an ammonia release equal to or greater than the Emergency Planning and Community Right to Know Act (EPCRA) and Comprehensive Environmental Response, Compensation and Liability Act (CERCLA) reportable quantity of 100 pounds, the following entities should be notified:

Section 5. Fire Fighting Measures

EXTINGUISHING MEDIA:Water Spray, Water Fog, Dry Chemical, Carbon Dioxide (CO2) or foam.

SPECIAL FIRE FIGHTING PROCEDURES:Must wear protective clothing and a positive pressure SCBA.Stop flow of gas or liquid if possible.Approach fire upwind and evacuate area downwind if needed.Use water spray to keep fire-exposed containers cool and control vapors.If a portable container (such as a cylinder or trailer) can be moved from the fire area without risk to the individual, do so to prevent thepressure relief valve of the trailer or portable container from discharging or the cylinder from rupturing. If relief valves areinoperative, heat exposed storage containers may become explosion hazards due to over pressurization.Stay upwind when containers are threatened.

UNUSUAL FIRE AND EXPLOSION HAZARDS:Outdoors, ammonia is not generally a fire hazard. Indoors, in confined areas, ammonia may be a fire hazard, especially if oil or othercombustible materials are present.Combustion may form toxic nitrogen oxides (NOx).

Section 6. Accidental Release Measures

GENERAL:Only properly trained and equipped persons should respond to an ammonia release.Wear eye, hand and respiratory protection and protective clothing; see Section 8, Exposure Controls / Personal Protection.Stop source of leak if possible, provided it can be done in a safe manner.Leave the area of a spill by moving laterally and upwind.Isolate the affected area. Non-responders should evacuate the area, or shelter in place.

SPECIFIC STEPS TO BE TAKEN:For a hazardous material release response, Level A and/or Level B ensemble including positive-pressure SCBA should be used. Apositive pressure SCBA is required for entry into ammonia atmospheres at or above 300 ppm (IDLH).Stay upwind and use water spray downwind of container to absorb the evolved gas.Do not apply water directly to container, unless there is heat impingement, as ammonia boils at -28 oF (direct water will heatcontainer), and more vapors will be released.Caution: Adding water directly to liquid spills will increase volatilization of ammonia, thus increasing the possibility of exposure.Contain spill and runoff from entering drains, sewers, streams, lakes and water systems by utilizing methods such as diking,containment, and absorption.

Section 7. Handling and Storage

SPECIAL PRECAUTIONS:Only trained persons should handle anhydrous ammonia. Store in well-ventilated areas, with containers tightly closed. Protect fromtemperatures exceeding 120 oF (48.8 oC). Protect containers from physical damage. Keep away from ignition sources, especially inindoor spaces. Do not use plastic. Do not use any non-ferrous metals such as copper, brass, bronze, tin, zinc or galvanized metals. Useonly stainless steel, carbon steel or black iron for anhydrous ammonia containers or piping.OSHA 29 CFR 1910.111 prescribes handling and storage requirements for anhydrous ammonia.Refer to Compressed Gas Association (CGA) G-2.1 for the recommendations for the storage and handling of anhydrous ammonia.

VENTILATION:Local exhaust should be sufficient to keep ammonia vapor below applicable exposure standards.

WORKPLACE PROTECTIVE EQUIPMENT:Protective equipment should be stored near, but outside of anhydrous ammonia area. Water for first aid, such as an eyewash stationand safety shower, should be kept available in the immediate vicinity. See 29 CFR 1910.111 for workplace requirements.

DISPOSAL:See Section 13, Disposal Considerations. Classified as Resource Conservation and Recovery Act (RCRA) Hazardous Waste due tocorrosivity with designation D002, if disposed of in original form.

Section 10. Stability and Reactivity

REACTIVITY:Anhydrous ammonia has potentially explosive reactions with strong oxidizers. Anhydrous ammonia forms explosive mixtures in airwith hydrocarbons, chlorine, fluorine and silver nitrate. Anhydrous ammonia reacts to form explosive products, mixtures orcompounds with mercury, gold, silver, iodine, bromine, silver oxide and silver chloride.

CHEMICAL STABILITY:Stable under normal ambient conditions of temperature and pressure. Heating a closed container causes vapor pressure to increase.Will not polymerize.

POSSIBILITY OF HAZARDOUS REACTIONS:Will react exothermically with acids and water.

CONDITIONS TO AVOID:Avoid anhydrous ammonia contact with chlorine, which forms a chloramine gas, which is a primary skin irritant and sensitizer.Avoid contact with galvanized surfaces, copper, brass, bronze, mercury, gold and silver. A corrosive reaction will occur.

INCOMPATIBLE MATERIALS:Anhydrous ammonia is incompatible with acetaldehyde, acrolein, boron, chloric acid, chlorine monoxide, chlorites, nitrogen tetroxide,perchlorate, sulfur, tin and strong acids.

HAZARDOUS DECOMPOSITION PRODUCTS:Anhydrous ammonia decomposes to hydrogen and nitrogen gases above 450 oC (842 oF). Decomposition temperatures may belowered by contact with certain metals, such as iron, nickel and zinc and by catalytic surfaces such as porcelain and pumice.

Section 11. Toxicological Information

Potential health effects: Ammonia is an irritant and corrosive to the skin, eyes, respiratory tract and mucous membranes. Exposureto liquid or rapidly expanding gases may cause severe chemical burns and frostbite to the eyes, lungs and skin. Skin and respiratoryrelated diseases could be aggravated by exposure. The extent of injury produced by exposure to ammonia depends on the duration ofthe exposure, the concentration of the liquid, gas or vapor and the depth of inhalation.

Exposure Routes:Inhalation (vapors, gas), skin and/or eye contact (vapors, liquid, gas).

Symptoms of acute exposure:Inhalation: Exposure may result in severe irritation and/or burns of the nose, throat and respiratory tract. May cause dyspnea

(breathing difficulty), wheezing, chest pain, bronchospasm, pink frothy sputum, pulmonary edema or respiratory arrest.Extreme exposure may result in death from spasm, inflammation or edema. Respiratory injury may appear as a delayedphenomenon. Pulmonary edema may follow chemical bronchitis. Brief inhalation exposure to 5,000 ppm may be fatal.

Skin: Irritation, corrosive burns, blister formation (vesiculation) may result. Contact with liquid may produce freeze burns(frostbite) and caustic burns.

Eyes: Vapors may cause severe irritation. Tearing, eye burns, permanent eye damage or blindness may occur. Effects of directcontact may range from irritation and lacrimation to severe injury and blindness.

Ingestion: Ingestion is unlikely since the material is a gas under normal atmospheric conditions. If ingested, it may cause burns andcorrosion, severe pain of the mouth, throat, esophagus and stomach or may be fatal

Chronic Exposure:Repeated exposure to ammonia may cause chronic irritation of the eyes and respiratory tract.

Toxicity:LC50 - 5131 mg/m3 (7338 ppm) to 11,592 mg/m3 (16,600 ppm), 60 minute exposure, Rat.LD50 - 350 mg / kg (Oral / Rat).

Not listed in the National Toxicology Program (NTP).Not recognized by OSHA as a carcinogen.Not listed as a carcinogen by the International Agency for Research on Cancer (IARC monograph).Germ cell mutagenicity information is not available. Reproductive toxicity information is not available.


Section 12. Ecological Information

Ammonia is harmful to aquatic life at very low concentrations. Notify local health and wildlife officials and operators of any nearbywater intakes upon contamination of surface water.

Toxicity:Terrestrial plants: LOEC = 3-250 ppm NH3.Aquatic plants: LOEC = 0.5-500 mg NH3-N/L.Acute toxicity to invertebrates: 48 h LC50 = 2.94 mg un-ionized NH3-N/L.Chronic toxicity to invertebrates: NOEC = 0.163- 0.42 mg un-ionized NH3/L.Acute toxicity to fish: 96-h: LC50 = 0.09 – 3.51 mg un-ionized NH3/L.Chronic toxicity to fish: NOEC = 0.025-1.2 mg un-ionized NH3/L.

Environmental Fate Information: Ammonia dissipates relatively quickly in ambient air and rapidly returns to the soil viacombination with sulfate ions or washout by rainfall. Ammonia strongly adsorbs to soil, sediment particles and colloids in water underaerobic conditions. Biodegradation of ammonia to nitrate occurs in water under aerobic conditions resulting in a biological oxygendemand (BOD).

Persistence/Degradability:Biodegradable in soil. Ozonation in the air. Soluble in water.Bioaccumulative Potential:Not applicable.Mobility in Soil:No additional information available.Other Adverse Effects:No additional information available.

the system down, activate an emergency shutdown switch. The locations of the five

emergency shutdown switches are as follows: inside the safety corridor, inside the fire

command station, inside the operations office, on the main compressor control panel, and

under the cooling tower.

5. If the source of the odor cannot be determined, Facilities Management will use

monitoring equipment to evaluate the level of ammonia and provide further investigation

if necessary.
