Flammable classes

Factory Mutual Research Corporation, Specification Testing Standard for Less Flammable. Class Number 3972, Norwood, MA, May 1989. 

Hazard assessment. A hazard assessment is required to assess the potential effects of an accidental (or intentional) release of a covered chemical/material. This RMP element generally includes performing an off-site consequence analysis (OCA) and the compilation of a five-year accident history. The OCA must include analysis of a least one worst-case scenario. It must also include one alternative release scenario for the flammables class as a whole also each covered toxic substance must have an alternative release scenario. USEPA has summarized some simplified consequence modeling... 

Flammable properties of fipronil product (e.g., Term-idor SC Termiticide) flash point >93°C (199°F) flammability class will burn. Closed containers may explode (due to the build-up of pressure) when exposed to extreme heat. Suitable extinguishing media include water spray, foam, CO2, and dry chemical media. Firefighters should be equipped with self-contained breathing apparatus and turnout gear.

The rating system and performance requirements for curtains are given on this basis by DIN 66 082-1980. Flammability classes, V-a to V-e, are characterized as follows Curtains in classes V-a and V-b are tested according to DIN 4102 concerning the flammability of building materials (cf. Section 3.2.1.1) and should meet the requirements of categories A2 and Bl, respectively. The inferior classes, V-c to V-e, correspond to the test results from DIN 54 336-1986 curtains in class V-c should...

But the first four share another distinction as well — all are classified by the NFPA, based on their flashpoint, as Flammable Class IB (nearly the least safe) because their flash points do not exceed 23 °C. The meaning of this outcome is that all equipment in which these solvents are used cannot have any places in which a spark could be generated. ... 

One can t fail to observe a soil common to both Tables 3.3 and 3.4. It s sperm oil (a waxy liquid obtained from sperm whales), which is printed near the bottom row of each table with a grey background. It s found in both tables because it can be cleaned with either type of cosolvent process — with flammable materials (Class II A), or with those not flammable (Class II B) ". This is frequently the case, and is one reason why the selection process is made with the aid of a spreadsheet — so that various possibilities can be explored.

A preaccelerated, thixotropic, unfilled isophthalic gelcoat formulated for the production of reduced flammability ( Class 1 2 to BS 476. 1971) mouldings, and designed specifically for application by brushing. Offers excellent weathering properties and is recommended for use in construction and land transport applications.
