1. What is the main purpose of the NESHAP regulations concerning
asbestos?
• Protect consumers from asbestos-containing products
• Limit use of asbestos in construction
• Minimize the release of asbestos fibers during renovation and
demolition
• Require personal protective equipment use during abatement
• NESHAP regulates asbestos emissions to protect public health during
demolition and renovation.
,2. Which federal agency enforces workplace safety standards for
asbestos exposure?
• NIOSH
• EPA
• OSHA
• DOT
• OSHA enforces workplace safety standards, including permissible
exposure limits for asbestos.
3. What is the current OSHA PEL (Permissible Exposure Limit) for
asbestos?
• 0.5 f/cc
• 0.1 f/cc
• 1.0 f/cc
• 0.01 f/cc
• OSHA's PEL for asbestos is 0.1 fibers per cubic centimeter of air over
an 8-hour TWA.
4. The Class I asbestos work category includes:
• Roofing repairs involving mastic
• Encapsulating vinyl floor tiles
• Removal of TSI and surfacing ACM or PACM
,• Cleaning of HVAC systems

• Asbestos cannot enter the workspace
• The HVAC system remains operational
• Negative pressure pulls outside air into the work area to prevent
asbestos escape.
8. A manometer is used to:
• Measure temperature changes
• Determine fiber concentration
• Monitor pressure differentials in containment areas
• Gauge noise levels
• Manometers confirm the negative pressure required for safe
containment.
9. Which of the following is not considered friable asbestos?
