    Study Notes

    Emergency Types and Priorities

    • Emergencies happen suddenly, disrupting routines and requiring immediate action.
    • Disasters are major emergencies causing injuries, deaths, property damage, or both.
    • Types include natural forces, fires, explosions, and system failures.
    • Priorities for people in emergencies focus on life and safety first, followed by property protection and restoring normalcy.

    SARA and EPCRA-SARA III

    • Superfund Amendments and Reauthorization Act (SARA) of 1986 mandates chemical plants develop emergency response plans.
    • EPCRA-SARA III helps communities plan chemical emergencies and requires industries to report on hazardous substance storage, use, and releases to federal, state, and local governments.

    Radiological Accidents and Chemical Transportation

    • Radiological accidents and chemical transportation emergencies require specific planning and reporting procedures.
    • Agencies such as FEMA and NRC provide resources for handling such emergencies.

    Disaster Dilemma and Fire Safety

    • Technology solutions can create new types of emergencies.
    • Monthly visual, hydrostatic, and annual internal evaluations and documentation are key for fire extinguishers and emergencies. A disaster dilemma is when technologies introduce emergencies.
    • Procedures for evacuation, those who remain, rescue, and medical duties need to be included in the written plan. Names for contactors will also be needed.
    • Employees need to be accounted for after the incident.

    Elevator Emergency Procedures

    • Elevators are designed to return to the primary recall floor in case of a fire to allow for the fastest evacuation possible
    • The primary recall floor is indicated on the control panel with an asterisk.
    • The elevator will stop one floor above or below the fire floor if it occurs in the primary recall floor.
    • Travel distance to an exit should not exceed 150 ft from any location within a building and 200 or 250 ft for industrial buildings without and with sprinklers respectively.
    • Stairways and corridors must be at least 44 inches wide.

    Fire Prevention Plans and Practices

    • Plans outline crucial information about handling different hazards, ignition sources, and fire protection procedures.
    • Maintain, store, and use fire protection equipment to control and prevent accidents.
    • Proper safety measures to control and avoid fire emergencies including potential factors and risks.
    • Procedures and materials to control hazardous substances.

    Interior Finishes and Construction

    • Interior finishes with lower flame spread and smoke indexes are preferable.
    • Proper design and construction techniques reduce fire hazards. Construction, materials, and procedures for preventing fire related to explosions.
    • Construction and design must prevent the spread of fire. Proper implementation of fire prevention plans to prevent the propagation of fires.
    • Fire protection measures should be implemented in new constructions.

    Bloodborne Pathogens and Workplace Safety

    • Hepatitis B vaccination series and annual bloodborne pathogens training required for employees with occupational exposure.
    • Provide initial and annual training to employees for all employees.
    • Understanding and adherence to all bloodborne pathogens, hepatitis B vaccination, and occupational safety regulations.

    Chemical Hazards Emergency Procedures

    • Escape procedures and escape route assignments must be known for chemical hazards.
    • Special protocols and systems needed for employees involved in critical operations.
    • Reporting systems and processes for fire and other emergencies
    • Training related to first aid, CPR, and self-contained breathing apparatus (SCBA) essential. Protocols for Chemical Spill Control Procedures,
    • Chemical spill control procedures need to be documented.

    Process Safety Management (PSM)

    • Companies must conduct regular Process Hazard Analyses (PHAs) and revalidate them every five years.
    • Emergency shutdown procedures should be incorporated into operating procedures.
    • Procedures related to an emergency action plan and mechanical integrity are required for PSM emergency systems.
    • Include employee training on how to appropriately respond to emergency releases, using the proper safety gear.
    • Provide appropriate safety instructions and supplies for hazardous material emergencies,
    • Conduct a hazard analysis (What-if, checklists, etc.)
    • Conduct a risk assessment, including analysis, for all of the above
    • Training related to safety protocols, equipment, and procedures in the scenario of emergencies, must be well recorded and documented.

    Fire Prevention and Control

    • Types and classes of fires (A,B,C,D,K); appropriate types of extinguishers to use;
    • Prevention measures (proper storage, safety devices, etc.).
    • Location of fire extinguishers should be visible and easily accessible.
    • Clear, well-maintained escape routes, exit routes and designated hazard zones.
    • Materials that can be combustible should be separated from areas that can burn.
    • Sprinkler systems, alarm systems, and other fire detection devices must operate as designed to prevent fires from spreading.
    • Prevent explosions and control sources of ignition.
    • Flammable materials should be properly stored and handled.
    • Training and awareness programs (periodic trainings) for employees regarding fire safety and safety procedures.

    Safety from Workplace Violence

    • Employers need a zero-tolerance policy toward workplace violence.
    • Workplace violence incidents must be documented.
    • Employee training on safety and response systems for emergencies
    • Security systems and practices need to be well-documented.
    • Measures to deter, detect, delay, and defend against violence should be included in the plan.

    Explosions and Dust Explosions

    • Preventing explosions, minimization of the spread of dust.
    • Preventing explosions by keeping oxygen levels low and controlling dust ignition.
    • Ensuring that the workplace has properly equipped fire detection devices, evacuation plans, and other safety measures for employees.

    Risk Communication and Media Relations

    • Preparing for an effective and credible communication plan in case of risks.
    • Identifying criteria for speaking with the media; ability to communicate the information in a clear and convincing manner
    • Training for effective communication, including speaking clearly, and with compassion
    • Coordinating with credible sources for accurate information.
    • Meeting media needs and responding in a timely manner
