In the likely event of the loss of containment, a lab ventilation is designed to ensure that the chemical fumes do not remain in the lab for an extended period. In the absence of an adequately designed LVS, these escaped contaminants settle on the furniture and fume hood surfaces, leading to the corrosion.
If treated and coated metal is corroding in these environments, the impact on the lungs of our users can only be imagined.
Fume hoods and other ECDs are complicated devices within the complex Lab Ventilation Systems. The systems are always in a state of flux, leading to continuous shifts in differential pressure.
If the LVS is not properly designed and operated, even the best ECDs cannot function as expected, leading to a major compromise in containment confidence. Thus, large sums of money are being spent to run systems that don’t really deliver the expected level of safety.
