    Study Notes

    Hazardous Materials Overview

    • Sensory clues in water for hazardous materials include dead fish, unusual algae growth, and white froth.
    • Exposure to poison in a household incident should be addressed using the product's label as the primary information source.
    • Routes of entry into the body for toxic substances: absorption, injection, ingestion, inhalation.

    Hazard Identification and Safety Regulations

    • NFPA 704 code OXY indicates materials that can easily release oxygen, increasing fire or explosion hazards.
    • Hydrogen cyanide disrupts the body's oxygen transfer to cells.
    • The Occupational Safety and Health Act ensures safe working conditions.
    • Small children are more susceptible to the effects of toxic accidents compared to adults and teenagers.

    Emergency Management and Response

    • A minimum of eight personnel is recommended to manage hazardous materials incidents safely.
    • Decontamination is essential to remove contaminants from people and equipment.
    • Local Emergency Planning Committees (LEPCs) are responsible for developing emergency response plans for hazardous materials incidents.
    • An emergency operations plan must be revised as necessary to ensure effectiveness.
    • The Environmental Protection Agency (EPA) is responsible for environmental protection against hazardous materials contamination.
    • Judiciaries may act to halt pollution immediately in extreme cases with clear and irreparable potential damage.
    • Lease landfills are insufficient for disposing of all national waste needs.
    • The Resource Conservation and Recovery Act of 1976 regulates hazardous waste management.

    Community and Training Measures

    • Effective community plans clarify roles and responsibilities during hazardous materials emergencies.
    • Cross-contamination can occur when contaminated clothing is handled by others.
    • Initial and ongoing training are essential for emergency preparedness and response.
    • Hazardous Materials Response Teams equip personnel to handle incidents effectively.

    Health Effects and Environmental Impact

    • Chronic exposure refers to health effects from long-term contact with hazardous substances.
    • A chemical classified as a mutagen causes permanent changes in genetic material (DNA).
    • Biomagnification describes the increasing concentration of chemicals in organisms higher in the food chain.
    • Point sources of pollution, like smokestacks, are identifiable pollution contributors.

    Safety and Awareness

    • Notify authorities upon encountering suspicious substances.
    • Emergency response preparation includes the understanding that in-place sheltering may be necessary during hazardous material incidents.
    • The Federal Emergency Management Agency provides training and resources to state preparedness for emergencies.
    • Understanding permissible exposure limits is crucial for workplace safety as designated by OSHA.
