What is the difference between level "b" and level "c" chemical protective garments

What is the difference between level "b" and level "c" chemical protective garments

• A. Level of respiratory protection
• B. Type of material
• C. Temperature rating
• D. Size

Answer: (A)

The main distinction between Level B and Level C garments is the level of respiratory protection they provide. Level B uses a self-contained breathing apparatus or a supplied-air respirator, giving the wearer air from a separate source and offering a high level of inhalation protection regardless of the surrounding atmosphere. The suit itself is protective, but the key safeguard is the independent air supply. Level C relies on an air-purifying respirator, which filters contaminants from the ambient air or uses a powered filter system. This means the wearer’s inhaled air depends on the surrounding environment meeting certain conditions (such as known contaminants and enough oxygen). In short, Level B offers higher respiratory protection via separate air supply, while Level C uses filtered ambient air and is appropriate when contaminants and conditions are well understood. Material, temperature rating, and size relate to the garment’s construction, but they don’t define the difference between these two levels—the respirator type and the degree of respiratory protection do.
