How to judge the toxicity of SF6 gas?

(1) If the mice exhibit normal activity throughout the 24-hour test and the 72-hour observation period, it indicates that the SF6 gas sample is non-toxic. This observation should be carefully recorded to ensure accurate interpretation of the results.

(2) If one or more mice show abnormal behavior or die during the test, this could suggest that the gas is toxic. In such cases, it is recommended to repeat the experiment using a new group of ten mice to confirm the findings and rule out any random or external factors that may have influenced the outcome.

(3) Whenever possible, any mouse that dies or displays severe signs of poisoning should be subjected to a post-mortem examination. This step helps identify the specific cause of death or poisoning, providing valuable insights into the potential risks associated with the gas sample.

(4) It is important to maintain detailed records of all observations, including the behavior, health status, and any changes in the mice over time. These records are crucial for evaluating the overall safety of the gas and for future reference in similar studies.

(5) The testing environment should be controlled and monitored to ensure that external variables do not interfere with the results. Factors such as temperature, humidity, and air quality can affect the behavior of the animals and must be kept consistent throughout the experiment.

(6) Researchers conducting the test should be trained and experienced in handling laboratory animals and interpreting their responses. Proper care and ethical treatment of the animals should always be a priority during the entire process.

(7) If the results are inconclusive or inconsistent, further investigation or additional tests may be necessary. This ensures that the conclusions drawn from the experiment are reliable and scientifically valid.
