Respondent owns and operates a pulp and paper mill. Respondent operates the pulp mill using the Kraft process to digest wood chips under pressure in batch digesters for pulp production. The finished cooked Wood chips are blown to blow tanks, Which reduce the pressure and separate steam and digester gases from the pulp. Uncondensed steam and gases generated by this process include regulated substances and other extremely hazardous substances. The un-condensed stream and gases are transferred via ducts through the Munters Mist Eliminator to the blow heat accumulator. The gases continue though the blow heat evaporators and additional processing that eventually recovers the gases into turpentine, removes the thermal energy, and condenses the steam.
One day a safety professional was walking his job site when he came across two workers using a forklift and stack of pallets unsafely. He/She intervened and instrcuted the workers and their supervisor that they would need to use the forklift basket to lift the worker(s) safely. They all agreed and the safety professional went on his way, assuming that the workers and supervisor would be able to correct this unsafe act with no more instruction as they had used the basket many times before. The next day he comes across this...
In my emergency response training around the country it is always an interesting discussion when Anhydrous Ammonia (NH3) comes up and the level of PPE necessary for a "safe response". I have always stuck to my 25 years of training that NH3 qualifies for LEVEL A as it meets all the LEVEL A criteria. However, there are a lot of folks who challenge me on this level of protection and many would even ask me to provide them with a reputable source that stated LEVEL A is necessary. Until now, those reputable sources were wishy-washy at best as to the level of PPE needed for NH3. Until now...
OSHA’s PSM standard requires Operating Procedures to address “special or unique hazards”
1910.119(f)(1)(iii) Safety and health considerations:
This item is often not necessary with many of the PSM standard’s Highly Hazardous Chemicals; however, HFO-1234yf has a unique property that falls into this requirement. HFO-1234yf is…
Examples of catastrophic failure of NH3 refrigeration vessels caused by stress corrosion cracking (FMCSA)
Cases of Stress Corrosion Cracking (SCC) in steel vessels using NH3 have been reported by members of the ammonia refrigeration industry. When NH3 is used as a refrigerant, it is kept at -33° C (-28° F). While it was once believed that NH3 SCC)could not occur at such low temperatures, both practical experience and experimental studies have shown otherwise. The Industrial Refrigeration Consortium (IRC) has developed classes and issued technical bulletins for its members to address the causes and prevention of NH3 SCC.
The IRC has identified non-stress-relieved (non-annealed) welds and areas exposed to condensing NH3 vapor as “hot spots” for SCC. In one incident, a SCC attack formed a hole through a high-pressure receiver line from an NH3 refrigeration system. The hole initiated on the inside of the vessel and grew completely through the weld and heat-affected zones to the exterior surface. After the leak occurred, the interior surface of that pressure vessel was examined with a liquid penetrant, and this showed that several SCC 5 to 10 cm long cracks were present, all oriented perpendicular to the weld line.
Other cases of failure have been reported by the International Institute of Ammonia Refrigeration:
The Chlorine Institute Pamphlet 65, Personal Protective Equipment For Chlor-Alkali Chemicals, has been updated and is available in the bookstore. This edition was updated to include new guidance on the use of contact lenses. Additionally, guidance on exposure limits, respiratory protection, and maintenance of PPE was expanded. Pictures and examples of levels of PPE and types of respirators were also included.
