Which category does the trichloroethylene storage tank belong to?

The flash point is 32.2°C; according to the classification criteria for fire resistance levels, since 28°C ≤ 32.2°C ≤ [upper limit], it falls into Category B1. (The data below is sourced from http://www.chemyq.com/xz.htm) Molecular formula: C2HCl3 Molecular weight: 131.39 CAS number: 79-01-6 Properties: Colorless, stable, low-boiling-point heavy oily liquid. It has a smell similar to chloroform. It is non-flammable, volatile, and does not react chemically with ordinary metals. It is miscible with common organic solvents and slightly soluble in water. Melting point: -87.1°C, boiling point: 86.7°C at 20.0°C (8.0 kPa); relative density (20/4°C): 1.4649; refractive index: 1.4782; flash point: 32.2°C; autoignition temperature: 410°C; critical temperature: 271°C; critical pressure: 5.02 MPa. It has low viscosity, and in humid air it can be slowly decomposed by light to produce hydrochloric acid. Triethanolamine, stearates, or cresol are often added as stabilizers, or 1% ethanol is added as an antioxidant.

I’m not sure if the information gathered is accurate or not! There are also those without a flash point available online.
