| Applies when | hydrofluoric acid, hf acid, hf |
|---|---|
| Avoid | single-wall without secondary containment (Storage Tank) |
| Recommend instead | Poly Processing SAFE-Tank (Storage Tank) |
| Rationale | Hydrofluoric acid penetrates tissue faster than typical acids, alters nerve function so exposure can go unnoticed (delaying treatment), and is absorbed through skin into the blood where it reacts with blood calcium and can cause cardiac arrest. XLPE gives 20x the environmental stress-crack resistance, 10x the molecular weight, and 5x the impact/tensile strength of HDPE. SAFE-Tank's tank-within-a-tank closed containment reduces health/environmental risk from the most dangerous chemical in this vendor's storage lineup; if SAFE-Tank isn't feasible, an IMFO flange reduces hands-on maintenance and therefore employee exposure risk. |
