Section 7: Key Points

What We've Covered

This section made the following main points:
  • Standards are legally acceptable exposure levels or controls set by Congressional or Executive mandate.
  • Guidelines are recommended maximum exposure levels and are voluntary and not legally enforceable.
  • Consumer products
    • The U.S. Consumer Product Safety Commission (CPSC) protects the public from unreasonable risks of harm connected with consumer products.
    • The CPSC establishes consumer exposure standards for hazardous substances and articles.
    • The CPSC requires warning labels on containers of household products that are toxic, corrosive, irritating, or sensitizing.
  • Drugs
    • FDA approval is required before pharmaceuticals can be marketed.
    • Animal studies and human clinical trials are required to determine toxic dose levels.
    • The New Drug Application (NDA) contains guidance for drug usage and warnings regarding side effects and interactions.
    • Information about a drug's harmful side effects must be provided through labeling and package inserts, publication in the Physicians' Desk Reference (PDR), and direct-to-consumer marketing.
  • Food additives
    • The FDA is responsible for approving food additives.
    • Direct additives are intentionally added to foods for functional purposes and include processing aids, flavors, appearance agents, and nutritional supplements.
    • Indirect additives are not intentionally added to foods and are not natural constituents of foods, but become constituents during production, processing, packaging, and storage.
    • FDA scientists must review new direct food additives before they can be used in foods.
    • Generally Recognized as Safe (GRAS) additives are generally accepted as safe for an intended use and can be introduced into the food supply without prior FDA approval.
  • Environment
    • The EPA establishes exposure standards for pesticides, water pollutants, air pollutants, and hazardous wastes.
    • Pesticides must be registered with EPA after undergoing extensive analyses.
    • The EPA prepares health advisories (HAs) as voluntary exposure guidelines for drinking water contamination.
    • Ambient water quality criteria help control pollution sources at the point of release into the environment.
    • National Ambient Air Quality Standards (NAAQS) protect public health and welfare from air pollution.
    • Hazardous wastes are regulated under the Resource Conservation and Recovery Act (RCRA) and Superfund.
    • RCRA regulates hazardous and non-hazardous solid waste.
  • Occupational Safety
    • The Occupational Safety and Health Administration (OSHA) establishes legal standards for worker exposure in the United States.
    • Permissible Exposure Limits (PELs) list air concentration limits for chemicals, but not skin absorption or sensitization.
    • Short Term Exposure Limit (STELs) PELs are concentration limits of substances in the air that workers may be exposed to for 15 minutes without adverse effects.
    • Ceiling limits are concentration limits for airborne substances that must not be exceeded.
    • Immediately dangerous to life or health (IDLH) designates an airborne exposure or atmosphere that could lead to death or immediate or delayed permanent adverse health effects.
    • Control banding (CB) determines a control measure based on a band of hazards, such as skin irritation or carcinogenic potential, and exposures.
