Study Notes

Incident Commander and Hazmat Operations

The Incident Commander oversees on-scene emergency response operations, requiring specific awareness and operational training.
APIET acronym stands for Analyze, Plan, Implement, Evaluate, Terminate, guiding the hazmat response process.

Incident Evaluation Processes

The Eight Step Process outlines fundamental tactical functions necessary for responding to hazardous material accidents.
Analyzing the product and its effects is crucial in the analysis of the incident.

Hazardous Materials Databases

A disadvantage of hazardous materials databases is variability in information across sites, which may be outdated.
Resources for identifying hazardous materials include databases, monitoring equipment, reference manuals, and technical information centers.

Incident Components and Elements

Key components of an incident include the product, container, and environment.
Elements of an incident cover conditions like spills, leaks, and fires.

Incident Subgroups and Toxicity Measures

Subgroups such as hazard, damage, and vulnerability are crucial in understanding incidents.
Counts per Million measures radioactivity, reflecting the level of exposure.

Health and Exposure Limits

Immediately Dangerous to Life and Health (IDLH) refers to conditions posing immediate health threats.
Lethal Concentration (LC50) is a dosage measure that can cause death, whereas Lethal Dose (LD50) indicates a dose likely to kill.

Exposure and Toxicity Regulations

Permissible Exposure Limit (PEL) is the maximum allowable concentration of a hazardous substance under OSHA regulations.
Threshold Limit Values (TLV) include:
- Ceiling (TLV-C): Maximum concentration not to be exceeded.
- Short-Term Exposure Limit (TLV-STEL): Average exposure over 15 minutes, not to be repeated excessively.
- Time-Weighted Average (TLV-TWA): Sustained exposure level for 8 hours daily without adverse effects.

Acute and Delayed Toxicity

Acute Toxicity refers to immediate severe symptom onset from a single exposure.
Delayed Toxicity develops over hours or longer post-exposure.

Exposure Routes and Effects

Routes of exposure include inhalation, ingestion, absorption, and injection.
Synergistic Effects result when the combined impact of multiple chemicals exceeds individual effects.

Types of Hazardous Agents

Biological Agents and toxins cause diseases, while Blood Agents disrupt oxygen transfer.
Nerve Agents affect the central nervous system, and Vesicants cause severe skin damage.

Change Exposure and Stress Management

Altering exposure can involve sheltering, evacuation, and using personal protective equipment.
Modifying applied stress includes moving stressors and shielding systems.

Containment and Mitigation Techniques

Methods for containment include Absorption, Adsorption, Covering, and Damming.
Neutralization chemically reacts with hazardous substances to reduce risks.

Protective Equipment Levels

Level A provides the highest protection for responders.
Level B is suited for high respiratory protection needs, while Level C offers chemical-resistant gear for lower risks.
Level D refers to standard work uniforms.

Incident Management and Control

The Incident Action Plan outlines strategic goals and support needs for the response.
Public Protective Actions (PPAs) include strategies for sheltering-in-place or evacuating populations.

Evacuation Procedures

Limited Scale Evacuations affect a few buildings, while Full-Scale Evacuations relocate large groups from hazardous areas.

Organizational Structure

The Optimum Span of Control typically consists of 5 individuals working under the command staff, which includes the Safety Officer and Public Information Officer.
Branches during incidents manage distinct operational segments, including Decontamination and Hazardous Materials Safety.

Regulatory and Planning Frameworks

SARA Title III requires local planning groups to establish hazardous materials response plans.
The Local Emergency Planning Committee (LEPC) is responsible for coordinating emergency response systems.

Emergency Planning and Authority

Emergency plans must address coordination roles, lines of authority, training needs, and medical response protocols.
Several government agencies oversee the regulation of hazardous material production, transportation, and disposal.
