ERG Guide
/GUIDE 137 SUBSTANCES - WATER-REACTIVE - CORROSIVE/ Fire or Explosion: EXCEPT FOR ACETIC ANHYDRIDE (UN1715), THAT IS FLAMMABLE, some of these materials may burn, but none ignite readily. May ignite combustibles (wood, paper, oil, clothing, etc.). Substance will react with water (some violently), releasing corrosive and/or toxic gases and runoff. Flammable/toxic gases may accumulate in confined areas (basement, tanks, hopper/tank cars, etc.). Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. Substance may be transported in a molten form. /Sulfuric acid; Sulfuric acid, with more than 51% acid; Sulphuric acid; Sulphuric acid, with more than 51% acid; Sulfuric acid, spent; Sulphuric acid, spent/

Frequently Asked Questions

What is an SDS (Safety Data Sheet)?

A Safety Data Sheet (SDS) is a standardized document that provides information about chemical hazards, safe handling, storage, emergency procedures, and transport classification. SDSs follow the GHS (Globally Harmonized System) format with 16 mandatory sections covering identification, hazards, composition, first aid, fire fighting, accidental release, handling, exposure controls, physical properties, stability, toxicology, ecology, disposal, transport, regulatory, and other information.

What do the GHS pictograms mean?

GHS pictograms are standardized hazard symbols: the flame (flammable), exclamation mark (irritant/harmful), skull and crossbones (acute toxicity), corrosion (corrosive), exploding bomb (explosive), flame over circle (oxidizer), gas cylinder (compressed gas), health hazard (serious health effects), and environment (aquatic toxicity). Each pictogram indicates a specific category of hazard.

What is an NFPA diamond?

The NFPA 704 diamond is a color-coded hazard rating system used by emergency responders. Blue = health hazard, Red = flammability, Yellow = instability/reactivity, White = special hazards. Each color section is rated 0 (minimal hazard) to 4 (severe hazard).
