Liquid ammonia is readily available, inexpensive, easy to clean up and the indicator chemicals in the cloth are very sensitive. Codes require audio-visual indication inside the compressor room and outside each entrance to the compressor room at 25 ppm. Phenolphthalein test paper changes from colorless to pink/fuchsia in the presence of ammonia. Mixtures involving ammonia contaminated with lubricating oil from the system, however, may have a much broader explosive range. Controller shall supervise wire runs and indicate a fault if communication with sensors is lost. iii. For a complete Ammonia Gas Detection System, add a QCC Quad Channel Controller with a top strobe, manual shutoff switch and a remote display. | All Rights Reserved |. The test papers are first dipped in distilled water & then exposed to the suspected gas leak. Consider installing ammonia detectors in areas where a substantial leak could occur if the facility is not manned 24 hours/day. The findings of this survey and other published data were used to develop this guidance. It can also be a building monitoring company, an auto-dialer, or other notification system that notifies responsible personnel 24/7. All wire runs should be supervised with the controller indicating a fault if communication with a sensor is lost. An uninterruptable power supply (UPS) that can run the system for a few minutes during the transition to emergency generator power should be utilized. Engineers responsible for refrigeration or process cooling systems will find the new Chillard 5000 Ammonia Leak Monitor from MSA (Cranberry, PA) offers them highly reliable toxic gas detection to protect people and equipment in the food/beverage, pharmaceutical, chemical, electric power generation and other industries. iii.

The controller shall provide three alarm setpoints per channel. Locate sensors in the breathing zone ~ 5 feet off of the floor. Codes require emergency ventilation at 150 ppm. Due to the huge amounts of Ammonia in storage, these industries require Ammonia gas leak detection systems for the safety and protection of personnel and property and to alert adjacent facilities and neighborhoods of a gas release. Ammonia leak detection cloth  can be used to detect leaks in equipment designed to be sealed or air-tight, such as incubators, pharmaceutical isolators, glove boxes, etc. An added benefit is that the test is reversible. Entrance monitor shall have a polycarbonate enclosure to prevent corrosion. Ammonia’s  low molecular weight (17.031 vs water 18.01528) makes it useful a detection tool  but safe handling is required since it can be toxic. Compressor Rooms are the most likely areas to leak ammonia and require at least two 0-250 PPM and one 0-5% fixed ammonia gas detectors connected to an alarm controller. The Ammonia Gas Detector has high sensitivity to ammonia gas. CO2 detection is required instead of ammonia detection in refrigerated and process areas. Locate sensor(s) in the breathing zone ~ 5 feet off of the floor. Ammonia is a simple inorganic molecule with the formula NH3. Chlorine Test Strips-Daycare Disinfection Checklist. One 0-250 PPM detector should be located under the normal ventilation fan. Copyright © 1994-2019 Indigo® Instruments. The sensor shall have a linear 4/20 mA output signal.

Ammonia leak detector(s) shall be stand-alone, wall-mounted unit(s), and have a solid-state instrument panel and sensor capable of sensing ammonia vapor concentrations of 0 to 1000 parts per million (PPM). D. What to do if an ammonia leak occurs? All output functions must be configured to latch, so even if ammonia concentrations fall below the setpoint, a manual reset is required under the supervision of a qualified operator. Not Like pH Strips? A means for monitoring ammonia concentration during a power failure must be provided (§16.1.4). The compressor room is the highest risk location in most plants. v. The sensor shall have a linear 4/20 mA output signal. ammonia leak detection systems and emergency isolation facilities. Safety When Using Ammonia (NH3) Locate sensors in the breathing zone ~ 5 feet off the floor. Others should be spaced in the breathing zone every 2000 square feet, about 5 feet above the floor. Ammonia leak cloth is excellent for leak tests since it is a very small molecule that can pass through very small holes. Use one 0-2% sensor located ~ 5 feet off the floor below the emergency ventilation fan so it samples airflow from throughout the room in an emergency condition. The sensor shall have potted electronics to protect circuit board and components. Ammonia Detection GDS Corp is proud to supply gas and flame detection systems to both national and international clients. Todays post comes from GCAP’s R-717 Tip of the Day brought to you from Jeremy Williams by Garden City Ammonia Program. Provide (1) GG-NH3-2% ammonia gas sensor for each Compressor Room.

Glove boxes are used for handling dangerous materials that are radioactive, chemically toxic or biologically active such as viruses. Any alarm condition should send a signal to a monitored location. Many commercial refrigeration systems have alarms that indicate ammonia leaks. Ultrasonic Leak Detector. This alerts operators to discharges of ammonia to atmosphere through the vent line so they can take action to mitigate the release. The controller shall provide a watertight enclosure to protect electronics and allow for outdoor installations where necessary. A July 2012 article published in the journal Clean Air and Environment1 discusses the difference between leak rate and leak detection and the ISO classification of leak tightness based on volume loss per hour2, 3.

Some insurance companies require shutdown of liquid feed and hot gas solenoids in the event of a leak (but the major codes currently do not). A cloth infused with the chemical indicator bromothymol blue can help pinpoint leak location much more accurately than a simple phenolphthalein test paper. We supply real-time monitoring systems with phone call alert or portable ammonia detectors. More demanding applications such as those in the nuclear industry use even smaller compounds such as tritium which is radioactive & needs specialized equipment. 10,000 ppm - Redundant Emergency Ventilation, Ammonia Compressor Room (0-250 ppm NH3 sensors), Ammonia Compressor Room Shutdown (0-2% NH3 sensor), Ammonia Refrigerated Rooms (0-100ppm NH3 sensor), Machinery under 100 HP not in Machine Rooms, and Equipment Pits, Remote monitoring of gas detection system, Machine Room De-energize compressors, pumps, & NC valves, 40,000 ppm or upper limit of detector. Locate other sensor(s) evenly distributed throughout the room. Refrigeration systems have ammonia detection systems that will alarm according to levels that are stated in the regulations. First and foremost, it’s a well-known fact that the most common refrigerants in use today are harmful to the environment, and the types of refrigerants that fall under this category include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), and hydrofluorocarbons (HFCs). Pharmaceutical isolators can be tested with a small dish of liquid ammonia placed inside the isolator which is then pressurized. See Warning and Alarm setpoints table for recommended setpoints. … A liquid leak will to the floor and if large enough can cool down a room so quickly that high concentrations are found on the floor with very low concentrations at the ceiling.
