What compressed gas cylinder does not require a safety relief device?

1. FLAMMABLE

2. OXIDIZER

3. POISON-A

4. NON-FLAMMABLE

The correct answer is: POISON-A

The correct answer is the option referring to non-flammable compressed gas cylinders, which do not require a safety relief device. Safety relief devices are essential for certain gases that could pose substantial hazards, such as flammable and oxidizing gases, which could react under pressure or heat, resulting in dangerous situations like explosions or fire. Non-flammable gases, typically inert substances, have a lower risk profile regarding reactions under pressure. As a result, they generally don’t produce the same potential hazards associated with the other types of gases, rendering safety relief devices unnecessary for their storage and handling. Understanding the nature of these gases allows for a focus on safety regulations and standards tailored to specific risks associated with each gas category, reinforcing the importance of proper handling and storage protocols in relation to the properties of the gases involved. Non-flammable gases maintain lower volatility and are less reactive, making their containment processes simpler and safer in many contexts.
