SAFETY DATA SHEET
TANNER INDUSTRIES, INC.
(National Ammonia, Northeastern Ammonia, Hamler Industries, Bower Ammonia & Chemical)
5811 Tacony St., Philadelphia, Pa 19135
CHEMICAL NAME: Ammonia, anhydrous CAS REGISTRY NO: 7664-41-7
SYNONYMS: Ammonia, liquefied
CHEMICAL FAMILY: Ammonia FORMULA: NH3 MOL WT: 17.03
COMPOSITION: 99+ % AMMONIA
STATEMENT OF HEALTH HAZARD
HAZARD DESCRIPTION: Irritant and corrosive to skin, eye, respiratory tract and mucous membranes. May cause severe burns, eye and lung injuries. Skin and respiratory related diseases aggravated by exposure.
Not recognized by OSHA as a carcinogen.
Not listed in the National Toxicology Program annual report.
Not listed as a carcinogen by the international Agency for Research on Cancer.
EXPOSURE LIMITS: Vapor: OSHA 35 ppm, 27 mg/m3, STEL, 15 minutes
25 ppm, 18 mg/m3, PEL
ACGIH 25 ppm, 18 mg/m3, TLV, 8 hour TWA
35 ppm, 27 mg/m3, STEL, 15 minutes
EFFECTS OF OVEREXPOSURE: Eye: lachrymation, edema, blindness. Skin: irritation, corrosive burns, blister formation. Contact of liquid with skin freezes the tissue, then produces a caustic burn. Inhalation: heavy, acute exposure may result in severe irritation of the respiratory tract, glottal edema, bronchspasm, pulmonary edema, respiratory arrest. Chronic effects: bronchitis. Extreme exposure (5000 ppm) can cause immediate death from spasm, inflammation or edema of larynx.
EMERGENCY AID: Eye: Flush with copious amount of water for 5 min. Eyelids: should be held open and away from eyeball to ensure thorough rinsing. SPEED AND THOROUGHNESS IN RINSING THE EYES IS MOST IMPORTANT IN PREVENTING LATENT PERMANENT INJURIES. Inhalation: move to fresh air. Administer oxygen or artificial respiration if necessary. Skin: flush affected area with copious amount of water for 15 min. Remove contaminated clothing while flushing. Do not rub affected areas. Do not apply ointments to skin burns. SEEK IMMEDIATE MEDICAL HELP.
NOTE TO PHYSICIAN: Eye injury may appear as delayed phenomenon. Pulmonary edema may follow chemical bronchitis. Supportive treatment with necessary ventilatory actions, including oxygen, may warrant consideration.

FIRE AND EXPLOSION HAZARD DATA
FLASH POINT: None. AUTOIGNITION TEMP: 651 C. (1204 F.) catalyzed by iron,
FLAMMABLE RANGE IN AIR: 16% to 25% by volume. 850 C. (1562 F.) uncatalyzed.
EXTINGUISHING MEDIA: Water spray or fog.
SPECIAL FIRE-FIGHTING PROCEDURES. Must wear protective clothing and respiratory protection. See PROTECTIVE EQUIPMENT. Stop source if possible. Cool fire exposed containers with water spray. Stay upwind and use water spray to knock down vapor and dilute. Let fire burn.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Not generally a fire hazard. If relief valves are inoperative, heat-exposed storage containers my become explosion hazards. Contact of ammonia with chemicals such as mercury, chlorine, iodine, bromine, silver oxide, or hypochlorites can form explosive compounds, Special hazard with chlorine to form chloramine gas, also a primary skin irritant and sensitizer. Combustion may from toxic nitrogen oxides. Revision: Nov. 94
STABILITY: Stable at room temperature. Exothermic reaction with acids.
CONDITIONS TO AVOID: Avoid mixing with chlorine bleach, sulfuric or other strong mineral acids, contact with galvanized steel, copper, brass, bronze, gold, mercury, silver, strong oxidizers, hypochlorites and halogens.
See EXPLOSION HAZARDS.
HAZARDOUS DECOMPOSITION PRODUCTS. Hydrogen and nitrogen gases above 450 C.
SPILL OR LEAK PROCEDURES
STEPS TO BE TAKEN: Wear respiratory protection and protective clothing, see PROTECTIVE EQUIPMENT. Shut off source if possible. Stay upwind from spills or leaks. Use water spray to absorb ammonia gas and dilute. Caution: Adding water to large spills may increase volatilization of ammonia, thus may increase possibility for exposure.
WASTE DISPOSAL: Listed as hazardous substance under CWA (40 CFR 116.4, 40 CFR 117.3 Reportable Quantity, 100#/45.4 kg.) Classed as a hazardous waster under RCRA (40 CFR 261.32 Corrosive, No. D002). Comply with all regulations. Spill will evaporate. Contaminated water may be used on agricultural land as fertilizer. Keep spill from entering streams or lakes.
SPECIAL PROTECTION AND PROCEDURES
RESPIRATORY PROTECTION: MSHA/NIOSH approved air-purifying type with full facepiece for work purposes; self-contained breathing apparatus for entry and escape in emergencies. Refer to 29 CFR 1910.134 and ANSI Z88.2 for requirements and selection.
VENTILATION: Engineering control to 25 ppm or less. Respiratory protection for higher vapor concentration. Refer to 29 CFR 1910.134 and ANSI: Z9.2 for requirements and selection.
PROTECTIVE EQUIPMENT: Gas-tights chemical goggles, respiratory protection, impervious outer clothing, gloves, overshoes as needed. Cotton work clothes recommended. Refer to 29 CFR 1910.132 to 1910.136 for requirements.
HANDLING AND STORING: Store in cool, well-ventilated area with containers tightly closed, OSHA 29 CFR 1910.111 prescribes handling and storage requirements for anhydrous ammonia as a hazardous material.
WORKPLACE PROTECTIVE EQUIPMENT as discussed above should be near, but outside of ammonia area. Eyewash and safety shower in immediate vicinity. See 29 CFR 1910.141 for workplace requirements.
DISPOSAL: Anhydrous ammonia is listed under RCRA and FWPCA. See WASTE DISPOSAL. Suitably diluted, ammonia may be disposed of on agricultural land as a fertilizer.
PERSONAL: Check availability of emergency equipment. Follow proper procedures. Wear needed protective equipment. Do not wear contact lenses.

Under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (CERCLA), Title III, Section 304, any accidental environmental release of this chemical equal to or over the reportable quantity of 100 lbs. must be reported promptly to the National Response Center, Washington, D.C. (1-800-424-8802). Any consumer product containing 5% or more ammonia requires a POISON label under FHSA (16 CFR 1500.129 (1). This material is subject to the reporting requirements of Section 313.

The information, data, and recommendations in this material safety data sheet relate only to the specific material designated herein and do not relate to use in combination with any other material or in any process. The information, data, and recommendations set forth herein are believed by us to be accurate. We make no warranties, either expressed or implied, with respect thereto and assume no liability in connection with any use of such information, data, and recommendations.
Effective June 21, 1999, companies with certain hazardous chemicals at specific threshold quantities must have developed, implemented, and registered a Risk Management Plan.
As part of the Clean Air Act Amendments of 1990, Congress directed the EPA to establish a regulatory program to prevent serious chemical accidents (Section 112(r)). The EPA published the final RMP rule on June 20, 1996, in 40 CFR 68. Anhydrous ammonia (TQ-10, 000 lb.) is one of the regulated chemicals.
Attached is a program comparison table and a program classification flow chart. The comparison table compares the different elements of each program. The classification flow chart will help in figuring out which program your plant will comply with.
The Baker Refrigeration staff is ready to assist you in meeting the requirements of the Process Safety or Risk Management standards.
Process Safety Management
Safety has become the most important issue in a plant’s operations. Baker Refrigeration’s services include all areas required by OSHA’s Process Safety Management (PSM) program and EPA’s Risk Management (RMP) program. The PSM standard is identical to the prevention program required by the RMP rule. The key elements of these programs include the following:
- Employee Participation
- Process Safety Information
- Process Hazard Analysis
- Operating Procedures
- Mechanical Integrity
- Management of Change
- Pre-Startup Safety Review
- Compliance Audits
- Incident Investigation
- Hot Work Permit
- Emergency Planning & Response
- Trade Secrets
Baker Refrigeration has been involved in the development and review of all elements of the PSM/RMP system. Our knowledge of the various ways these standards have been implemented at various client locations can assure that tailored, cost effective solutions can be developed should there be any improvement opportunities in your program.
