Study Notes
Emergency Personnel Goals
- Ensure the safety of rescue personnel during hazardous materials incidents.
- Remove patients from danger and perform patient decontamination.
- Provide definitive treatment following standardized protocols.
- Hazmat units have expanded drug inventories and specialized antidote therapy initiated by certified Hazmat Medics.
Patient Assessment Protocols
- Treat patients suspected of chemical contamination while considering potential underlying conditions.
- Identify the hazardous substance using reference guides:
- North American Emergency Response Guidebook
- NIOSH Pocket Guide
- Emergency Care for Hazardous Materials Exposure
- Handbook of Poisoning
- Poison Control Center (1-800-222-1222)
- Separate victims from hazardous agents, using trained personnel equipped with appropriate PPE.
General Care (EMR/BLS)
- Conduct primary assessment while initiating gross decontamination.
- Address life-threatening emergencies before focusing on decontamination and supportive measures.
- Chemical-specific ALS treatments only for identified contaminants or symptomatic cases consistent with known exposures.
Carbon Monoxide (CO) Overview
- CO is a colorless, odorless gas, a byproduct of incomplete combustion.
- Binds with hemoglobin to form carboxyhemoglobin, impairing oxygen transport in blood.
- Symptoms include headache, dizziness, chest pain, and severe cases can lead to seizures or coma.
BLS for CO Exposure
- Remove patients from contaminated environments.
- Use RAD-57 Procedure 44 to measure SpCO levels.
- Administer oxygen via NRB mask at 15 L/min or ventilate with BVM if unresponsive.
ALS for CO Exposure
- Initiate airway management if needed; intubate if required.
- Administer Narcan (0.5 mg IV/IM) for respiratory depression signs, following CO poisoning protocols.
- Transport based on SpCO levels; higher levels necessitate ALS transport to appropriate facilities.
Organophosphates & Carbamates
- Organophosphate insecticides are absorbed through skin, GI tract, and respiratory tract; Carbamates less so.
- Inhibit cholinesterase, leading to excess acetylcholine accumulation and overstimulation of the nervous system.
- Symptoms can be remembered using mnemonics “SLUDGE” (muscarinic symptoms) or “DUMBELS” (nicotinic symptoms).
BLS for Organophosphate Exposure
- Administer oxygen via NRB mask and suction airway as needed.
ALS for Organophosphate Exposure
- Administer Atropine (2 mg IV/IO) based on symptom severity; repeat as needed.
- Manage seizures with Midazolam (5 mg slow IV/IM/IO) until control is achieved.
Cyanide (CN) Symptoms
- Extremely toxic; affects oxygen utilization at the cellular level.
- Exposure can lead to rapid onset neuro, cardio, and respiratory symptoms.
- Death can occur within minutes after inhalation.
BLS for Cyanide Exposure
- Document carboxyhemoglobin readings and initiate oxygen therapy.
ALS for Cyanide Exposure
- Implement airway management and establish vascular access.
- Administer Hydroxocobalamin (5 gm IV over approximately 15 minutes); Sodium Thiosulfate if necessary.
Hydrogen Sulfides & Mercaptans
- H2S is a colorless gas with a rotten egg odor; highly toxic and can cause olfactory paralysis.
- Exposure leads to acute respiratory symptoms or syncope in high concentrations.
BLS for Hydrogen Sulfide Exposure
- Administer oxygen via NRB mask.
Adult Care for Hydrogen Sulfide Exposure
- Use Amyl Nitrite inhalants while providing oxygen.
- Administer Sodium Nitrite IV after Amyl Nitrite therapy.
Nitrogen-Containing Compounds
- Found in household products and associated with methemoglobinemia.
- Cyanotic appearance indicates significant impairment in oxygen transport.
BLS for Nitrogen-Containing Compounds
- Administer oxygen via NRB mask.
Adult Care for Nitrogen-Containing Compounds
- Methylene Blue (1-2 mg/kg IVP) if altered mental status is evident.
Hydrofluoric Acid (HF) Characteristics
- HF exposure causes intense painful burns exceeding visible injury areas.
- Systemic absorption can lead to severe outcomes like cardiac arrest.
BLS for HF Exposure
- Provide oxygen via NRB mask.
Adult Care for HF Exposure
- Use PPE and decontaminate affected skin; apply Calcium Gluconate Gel.
Aromatic Hydrocarbons & Gasoline
- Inhalation can cause serious cardiac dysrhythmias.
Adult Care for Inhaled Hydrocarbons
- Treat tachydysrhythmias per protocols; avoid administering Epinephrine.
Acid Mist/Chlorine & Ammonia Gas
- Low concentrations produce irritations; higher levels can lead to pulmonary edema.
BLS for Acid Mist/Chlorine Inhalations
- Administer oxygen via NRB mask, followed by ALS for further management.
Chemical Nerve Agents
- Organophosphates (e.g., Tabun, Sarin) require immediate care due to severe absorption through skin.
BLS for Chemical Nerve Agents
- Provide oxygen and manage airway issues promptly.
ALS for Chemical Nerve Agents
- Administer Atropine and manage seizures with Midazolam; continuous monitoring of symptoms is essential.
