Fume Hood Containment Test Not Approved Before Final Payment Email Template

Use this page when final payment is delayed because the buyer says the fume hood containment test, hood face-velocity acceptance, or containment signoff still lacks approval. This page is for laboratory or process spaces where the blocker is the proven containment performance of the hood, not general extract air balancing. The commercial problem is that the installation may already be complete, but the payer is still holding the final balance until the containment evidence is accepted. Your email should ask whether the fume hood test is the only remaining blocker, whether the latest containment test has already been completed, what hood, sash condition, or velocity result remains unresolved, and whether payment will be released once the report is approved. The goal is to reduce the delay to one exact lab-safety performance deliverable instead of generic comments about incomplete ventilation validation.
