Chemical Hygiene Officer Practice Exam

Chemical hazard categories describe the inherent properties of a chemical that can cause harm, such as the ability to ignite or burn. Flammability is one of these categories because it indicates how readily a substance can catch fire or sustain combustion, which is essential for safe storage, handling, and labeling. This concept guides controls like proper separation from ignition sources and appropriate fire protection measures. The other items are hazards related to equipment or physical injury (a glass rod is a physical hazard from breakage or sharp edges; pinch points and gears are mechanical hazards), not hazards arising from the chemical’s properties. Understanding flammability helps you apply the right safety controls for chemicals, such as using flammable storage cabinets and avoiding sparks or open flames around such substances.
