3. Hazards Identification

Emergency Overview: This product contains two (2) strains of Pseudomonas aeruginosa, a species rated BioSafety Class 2 by the Centers for Disease Control, but this pair of strains has been tested deficient for Toxin-A production, making them as safe as species identified as BioSafety Class 1, like the other nine (9) strains in this formula. BioSafety Class 1 microorganisms are defined by the Centers for Disease Control to be unlilkely to cause disease in healthy humans or animals. However, persons with compromised immune systems should avoid contact with open wounds and/or breathing dust or mist from manufacturing processes. These organisms are susceptible to many commonly used antibiotics, and Alken-Murray is willing to supply antibiotic sensitivity information to any doctor or import health authority requesting it.


A pair of autotrophic nitrifier strains, Nitrosomonas europaea and Nitrobacter winogradskyi, included to oxidize ammonia and nitrite, were grown in a sterile aqueous medium containing nutrients identified in section 2 of this MSDS, but following fermentation, ultra-filtration (designed to increase concentration of bacterial cultures, while discarding excess water and micro-nutrients to minimize total volume and weight of finished product). A trio of endospore-forming Bacillus cultures, one strain of Enterobacter cloacae, three strains of Pseudomonas putida and the pair of Pseudomonas aeruginosa, mentioned in the first paragraph in this section, were also grown individually in specialized sterile aqueous media, containing a variety of nutrients, but as heterotrophic bacteria, nutrients used include corn syrup solids, digests of soybean and/or skim milk, glucose or other sugars, vegetable oils, including olive oil, yeast extract, butterfat, starch, mineral salts, etc. The residual concentrations of these nutrients is believed to be below levels capable of triggering irritation, which also assures that product cultures will switch over to using the tank, pond or lake pollution as their sole nutrition, within six to twelve hours after hydration and application.


Since this product is no longer manufactured, we no longer offer its "confidential specifications sheet", protecting our proprietary formulae,except as needed for distributors to import those products to their countries.


Potential Health Effects:

  • Signs and Symptoms of Acute Overexposure: Eye, skin irritation
  • Signs and Symptoms of Chronic overexposure: Dermatitis and skin sensitization
  • Medical Conditions Generally Aggravated by Exposure: Allergies, dermatitis.
  • Ingestion: No effect if ingested in small amounts. Relative to other materials, a single dose of this product is rarely toxic by ingestion. Irritation of the mouth, pharynx, esophagus and stomach can develop following ingestion.

4. First Aid Measures

  • Inhalation: Remove victim to fresh air
  • Ingestion: Give victim water or milk to drink to dilute the product. Get medical advice..
  • Skin Contact: Remove contaminated clothing and footwear. Wash skin with soap and water. Wash clothing before reuse.
  • Eye Contact: Immediately flush eyes with water for 15 minutes. Get medical attention.
  • Note to Physician: If patient's immune system is compromised, request antibiotic sensitivity chart from Alken-Murray Corporation by e-mail:

13. Disposal Considerations

RCRA Hazard Class (if discarded): Neat, unused product is not considered a hazardous waste, according to RCRA regulations 40 CFR 261. . For proper disposal of used materials, an assessment must be completed to determine the proper waste management options permissible under applicable rules, regulations and/or laws governing client's location. Use until less than 1 inch remains in the container. Disinfect container with a 1% sodium hypochlorite solution, triple rinse with clean water, and pour rinse water to sewer. Then remove or deface product label to avoid confusion if pail or drum is later refilled. Clean, empty containers should be recycled or disposed of through an approved waste management facility.
