Nonflammable degreasers are the safest options if they will be used near sparks, open flames, or hot surfaces. Techspray has several nonflammable degreasers available, including G3 Maintenance Cleaner, PWR-4 Industrial Maintenance Cleaner, and Precision-V Maintenance Cleaner & Flux Remover.
The most common method of identifying the flammability rating of a degreaser is the GHS (Global Harmonized System) flammable pictogram (see diamond symbol above). Other standards, like NFPA (National Fire Protection Association) and HMIS (Hazardous Materials Identification System), provide a rating from 0 to 4, zero being the lowest flammability rating equivalent to nonflammable.
