Mastering HAZWOPER: Hazardous Waste Operations Compliance Quiz

The correct categories of waste under RCRA are toxic, ignitable waste, corrosive, and reactive. Non-hazardous, bio-degradable, and radioactive are not part of the RCRA categories.

The correct answer is States because they are the administrators of RCRA as per the Resource Conservation and Recovery Act. While the federal government has oversight, states are primarily responsible for implementing and enforcing RCRA regulations.

The concept of 'cradle to grave' implies continuous ownership and responsibility for an item from its creation until its ultimate disposal, even if used unlawfully by another party.

SUPERFUND triple indemnity refers to a situation where the state provides immediate financial assistance, but the recipient will have to repay the amount in the future. It does not mean receiving triple the initial payment or multiple payments without any repayment obligations.

CERCLA, also known as Superfund, is a federal law designed to clean up and manage hazardous waste sites. It imposes liability for the release or threatened release of hazardous substances and pollutants. The correct answer clarifies that if an entity generates a specific amount of waste, there are regulations regarding its disposal frequency to ensure environmental protection and compliance.

The Hazardous Waste Operations and Emergency Response (HAZWOPER) regulation was created in 1981 by the Occupational Safety and Health Administration (OSHA) to protect workers involved in hazardous waste operations.

SARA Title III specifically pertains to the Superfund Amendments and Reauthorization Act, which amended CERCLA to involve the community more and established regulations under EPCRA. It does not relate to healthcare access or transportation safety.

LD5 is based on a healthy 23 year old man as a standard reference point for certain measurements and assessments.

LD50 #s refer to the lethal dose that causes death in 50% of the test subjects. Therefore, a higher LD50 number indicates that the substance is less toxic, as it requires a higher dose to cause harm.

Nephrotoxins are substances that are toxic to the kidneys.

OSHA PEL stands for Occupational Safety and Health Administration Permissible Exposure Limit. It is a measurement of the maximum allowable concentration of a hazardous substance in the air averaged over a specified time period. The correct answer explains that PEL is a time-weighted average based on specific work duration assumptions and is measured in parts per million (ppm). The incorrect answers provide false information about PEL to test understanding of the concept.

OSHA STEL stands for Occupational Safety and Health Administration Short Term Exposure Limit, which refers to the maximum average concentration of a substance that a worker can be exposed to over a short period of time (usually 15 minutes) up to 4 times a day without experiencing adverse effects.

The OSHA Ceiling limit refers to the maximum allowable exposure level that should not be exceeded to ensure safety in the workplace.

NIOSH stands for National Institute for Occupational Safety and Health and provides recommended exposure limits on 10hr TWA. It is important to note that for the state of NY, the use of NIOSH is mandatory.

ACGRH stands for american conference for governmental industrial hygienists which provides threshold limit values (TLV) for various substances to ensure safe working environments.

The 'Action level' in occupational safety and health refers to the approach where when using multiple standards, the more conservative standard is divided by 2 to determine the permissible limit.

The correct standard levels for Acetone are OSHA PEL = 1000ppm, NIOSH REL = 250ppm, ACGIH TLV = 500 ppm. The Action level is calculated as 1/2 of the NIOSH REL, which is 125ppm in this case.

The correct answer provides examples of common types of asphyxiants and how they affect the body by displacing or preventing oxygen uptake. The incorrect options provide misleading information to test the understanding of different types of asphyxiants.

The correct answer is 20.9%. Oxygen levels are considered normal at this percentage. However, problems may start when the levels drop to 16%.

Gases/vapors are commonly measured in parts per million (ppm), which indicates the concentration of the gas in the air or another medium.

The unit mg/m3 typically measures the concentration of air pollutants in the atmosphere, not solids, liquid volume, or temperature.

Z-tables show the probability density functions (PDFs) for a standard normal distribution, representing the probabilities of obtaining a certain z-score in a normal distribution.

Chemical numbering systems are crucial for identifying and categorizing chemicals for various purposes. The correct answer provides information on three commonly used systems - CAS, RTECS, and DOT. The incorrect answers are other organizations or numbering systems that are not primarily focused on chemical numbering.

Skin designation refers to the potential of a substance to be absorbed through the skin and into the bloodstream, rather than measuring physical attributes such as thickness, color, or elasticity.
