OSHA #511 Occupational Safety and Health Standards for General Industry course

Which type of liquids includes those with flashpoints at or above 140°F and at or below 199.4°F?

1. Category I liquids

2. Category II liquids

3. Category III liquids

4. Category IV liquids

The correct answer is: Category IV liquids

The classification of liquids based on their flashpoints is an important aspect of understanding fire and safety regulations. Category III liquids are defined as those that have flashpoints at or above 140°F and at or below 199.4°F. This classification is significant because it helps in assessing the potential hazards associated with these liquids in various work environments. These flash point ranges determine how a liquid might behave under heat and are crucial for safety protocols, especially in general industry settings. Knowledge of these categories is vital for properly storing, handling, and using these liquids to mitigate risks of fire or explosion. Understanding this classification allows employers and employees to adhere to OSHA standards for handling potentially hazardous materials safely. In contrast, Category I liquids are those with flashpoints below 73°F, which present a higher risk. Category II liquids have flashpoints at or above 73°F and below 140°F, still indicating flammable characteristics but at different thresholds. Category IV liquids are those with flashpoints at or above 200°F, falling into a lower risk category. This structured classification system helps in determining necessary safety measures and training for working with various types of liquids.
