USM Ice Arena Ammonia Chiller/Emergency Response Refresher 2015
Objectives: • Identify and understand the hazard(s) • Review operational requirements • Review emergency response procedures
A Brief History of Ammonia: • Romans: Mined ammonium chloride • Europeans: Used for alchemy • Germans: First industrial use (WWI) • Today: • Fertilizers • Pharmaceuticals • Commercial cleaning products • Refrigeration
What Is It? • Ammonia - compound of Nitrogen and Hydrogen (NH 3 ) • Anhydrous- without water Boiling Point -28°F Weight per gallon of liquid at -28°F 5.69 pounds Weight per gallon of liquid at 60°F 5.15 pounds Specific gravity of the liquid (water=1) 0.619 Specific gravity of the gas (air=1) 0.588 Flammable limits in air 16-25% Ignition temperature 1204°F Vapor pressure at 0°F 16 psi Vapor pressure at 68°F 110 psi Vapor pressure at 100°F 198 psi One cubic foot of liquid at 60°F expands to 850 cubic foot of gas
Properties: • Becomes a liquid when pressurized/cooled. Colorless gas at standard pressure/temperature • Expands 850 times when evaporating • Easily absorbed by water • Lighter than air and will rise in dry air, but reacts immediately with humidity in the air and may remain close to the ground • DOT: Nonflammable • Alkali (irritant/corrosive) • Can corrode copper, zinc, and many alloys. Incompatible with mercury
Hazards: OSHA PEL (8 hr) • Repeated exposure does not produce chronic effects • “The dose makes the poison” • Eyes: Mild irritation to destruction of eye tissue • Throat/Lungs: Irritation, convulsive coughing, difficult or painful breathing, pulmonary congestion, death • Skin: Freezing burns, liquidation of skin tissue
Basic First Aid: • Exposure to Eyes/Skin: • Decontaminate all affected areas with water immediately. Flush for at least 15 minutes. • Ingested: • Have victim drink large amounts of water. Do not induce vomiting. • Inhaled: • Go to a clean, uncontaminated area. Remember- in the event of any significant exposure, seek advanced medical care immediately.
Ammonia at USM • Anhydrous ammonia system • Provides cooling for Ice Arena • Approx. 725 lbs. of ammonia (99% concentration) on site in compressor.
Basic Monitoring Available: • Building is equipped with ammonia detection. The Manning meter is located in the Olympia Room. The detection module is located behind the control panel in the lower level compressor room. • The meter offers a visual indication of ammonium concentration in parts per million (ppm). • At 25ppm, building alarm and exhaust fan (low) are activated. • At 50 ppm, building alarm, exhaust fan (high), and exterior warning lights are activated. • A separate Cimco detector/alarm activates at 150ppm
Preventative Maintenance: • Establish and maintain up-to-date records of system readings and equipment maintenance. • Space and equipment should be kept reasonably clean with minimal rust and corrosion. • Equipment should be cleaned and lubricated according to manufacturers recommendations. • All leaks should be repaired ASAP. • Annual servicing required; • Electrical connections • Pressure gauges • Ammonia detection system • Room ventilation system • Safety controls and interlocks
Ammonia Chiller Room Access Authorization • Employee and vendor access is limited. • A minimum of two authorized people may enter the space at any one time. • The Ammonia Chiller room access log is maintained by Ice Arena management. • The Log requires the following information: • Employee/Vendor name • Reason for Access • Date/Time entering space • Date/Time exiting space • The access log will be checked regularly by EHS & DFM. • Notify Public Safety before entering and after exiting. • Annual training is required for Ammonia Chiller room access.
Ammonia Chiller Room Authorized Employee/Vendors • Ice Arena Manager • Ice Arena Maintenance staff • Miller Refrigeration Technicians • USM Public Safety • Gorham Fire Department • USM EH&S Director & Staff • Trained DFM Management and Trades • Card Services
Emergency Response Outline: University of Southern Maine Ice Arena Gorham, Maine Ammonia Chiller System EMERGENCY RESPONSE PLAN
Alarm Activation: • Alarm system activates. Strobe lights are triggered, and audible alarm states: “MAY I HAVE YOUR ATTENTION PLEASE MAY I HAVE YOUR ATTENTION PLEASE THERE HAS BEEN A FIRE REPORTED IN THE BUILDING PLEASE PROCEED TO THE NEAREST EXIT AND LEAVE THE BUILDING” • All spectators, officials, athletes, coaches and personnel are to evacuate the arena and adjoining rooms immediately.
Emergency Evacuation: • Upon hearing the alarm and announcement, arena occupants are to exit the front doors and proceed immediately out onto the sidewalk and to the side of Hill Gym. • USM employees are asked to assist in facilitating the evacuation. • Evacuees are to proceed down the sidewalk to the front end of the gym and wait for further instructions. • Evacuees need to be aware of rescue vehicles approaching. • This process is vital to ensure that emergency response personnel, equipment and units can respond without crowd interference.
Emergency Evacuation: • Before leaving the ice and/or locker rooms, ice skating participants are to remove their skates. • Parents/guardians may wish to wait for small children before evacuating the ice arena. • Coaches/instructional personnel are to accompany their athletes/participants out of the arena.
Emergency Evacuation: • Upon evacuation, ice arena personnel are to assist evacuating arena occupants outside, and wait outside the arena front doors for the arrival of the USM Police and the Gorham Fire Department. • Alternate Evacuation: • If downwind of an outdoor ammonia release, or faced with a hazardous weather condition, alternative refuge may be taken in the Fieldhouse or the Brooks Dining Center. Note: Gorham FD can require evacuation of all Athletic facilities depending on the state of the emergency. • Off-campus evacuation routes are to be determined by the Police/Fire when necessary.
