PPE/Hazardous Materials Flashcards
sem 1 (39 cards)
What percentage of freight trains carry hazardous materials?
Approximately 35% of freight trains are known to carry hazardous materials, posing risks during transit.
What percentage of transport vehicles are involved in hazardous materials movement?
10% of all transport vehicles are involved in the movement of hazardous materials, increasing the likelihood of exposure during emergency responses.
Why is awareness of hazardous materials crucial for emergency responders?
Awareness of hazardous materials is crucial for safety during all emergency calls.
What are the five primary pathways of exposure to hazardous materials?
Exposure to hazardous materials can occur through inhalation, ingestion, injection, absorption, and radiation.
What factors influence the severity of exposure to hazardous materials?
The severity of exposure is influenced by time of exposure, concentration of the material, and the dose received by the body.
What are acute and chronic effects of exposure to hazardous materials?
Acute effects manifest immediately or shortly after exposure, while chronic effects may develop over time, including serious conditions like cancer and respiratory diseases.
What are local and systemic effects of hazardous material exposure?
Local effects can include burns and swelling, while systemic effects may lead to organ failure and birth defects.
What are the four levels of protection for hazardous materials?
The four levels of protection are A, B, C, and D, based on respiratory and skin protection needs.
What does Level A protection include?
Level A provides the highest protection, including SCBA (Self-Contained Breathing Apparatus) and full protective gear, used when the material is identified.
What is the purpose of Level B protection?
Level B offers high respiratory protection but lesser skin protection, suitable when the chemical is not known to absorb through the skin.
When is Level C protection used?
Level C is used when the concentration and type of airborne substance are known, allowing for air-purifying respirators and coveralls.
What does Level D protection indicate?
Level D is the lowest level, indicating no hazards in the atmosphere, where basic protective gear is sufficient.
What should responders do in cases of unknown hazardous materials?
Responders should approach from upwind and maintain a safe distance (approximately 800 meters).
What is advised if hazardous or radioactive materials are suspected?
Withdrawal is advised until safety is confirmed.
What should responders do before attempting patient rescue in hazardous situations?
Do not attempt patient rescue until the area is deemed safe; initiate care and transport only when conditions allow.
What is hydrogen sulfide (H2S)?
Hydrogen sulfide is a toxic, flammable, and colorless gas that poses immediate dangers to life and health (IDLH) at levels of 100 parts-per-million (ppm).
What are the exposure limits for hydrogen sulfide?
Exposure limits for H2S include: 10 ppm (beginning of eye irritation), 50-100 ppm (slight conjunctivitis and respiratory irritation), 100 ppm (severe symptoms can develop), 500-700 ppm (loss of consciousness), and 1000-2000 ppm (immediate unconsciousness).
What immediate tasks should EMS personnel perform in a hazardous materials situation?
Isolate the area, identify the hazardous material from a safe distance, and recognize immediate dangers.
What is the importance of universal precautions in healthcare?
Universal Precautions involve assessing risks and implementing measures to reduce exposure to hazardous substances, including antineoplastic drugs.
What types of communicable diseases are there?
Types include bloodborne diseases (Hepatitis B and C, HIV/AIDS), respiratory diseases (TB, Influenza, Measles, COVID-19), and fecal-oral route diseases (Hepatitis A, C. Diff).
What are key prevention measures for communicable diseases?
Frequent hand washing, proper vaccinations, patient isolation, and use of protective equipment are essential.
What are the guidelines for using personal protective equipment (PPE)?
Always work from ‘clean to dirty’, change gloves if torn, and ensure masks cover the nose and mouth completely.
What rights do patients have regarding confidentiality?
Patients have the right to confidentiality regarding their health information; it cannot be disclosed without consent.
What responsibilities do employers have regarding hazardous materials?
Employers must provide training and equipment to prevent exposure to hazardous materials.
