What is the recommended time for decontamination?
What is the recommended time for decontamination?
Direct victims through the primary decontamination corridor. Wash time should be at least 30 seconds but no longer than 3 minutes to ensure thorough soaking. (After 3 minutes, tissue damage from increased chemical absorption may occur with some chemical agents.)
What are the 3 steps of decontamination process?
There are three levels of decontamination: cleaning, disinfection and sterilization.
Which method is most effective for the decontamination of individuals?
All infectious materials and all contaminated equipment or apparatus should be decontaminated before being washed, stored, or discarded. Autoclaving is the preferred method. Each individual working with biohazardous material should be responsible for its proper handling.
What are the two types of decontamination?
Besides the two types of contamination, there are also two primary types of decontamination, technical and emergency.
What is the most basic level of decontamination?
What is the most basic level of decontamination? decontamination. The elimination of pathogens or other substances from a spoiled implement or surface; there are at least three levels of decontamination, the most effective being sterilization, then disinfection, and the lowest level, sanitization.
What is the last step in a basic six step decontamination?
Physically remove contaminants by, for example, dislodging/displacement, rinsing, wiping off, and evaporation; Inactivate contaminants by chemical detoxification or disinfection/sterilization; or. Remove contaminants by a combination of both physical and chemical means.
What are the levels of PPE?
Levels of PPE
- Full-face or half-mask, air-purifying respirator (NIOSH approved).
- Chemical resistant clothing (one piece coverall, hooded two piece chemical splash suit, chemical resistant hood and apron, disposable chemical resistant coveralls.)
- Gloves, outer, chemical resistant.
- Gloves, inner, chemical resistant.
Which type of nerve agent is the most persistent?
VX is the least volatile of the nerve agents, which means that it is the slowest to evaporate from a liquid into a vapor. Therefore, VX is persistent in the environment.
What liquid do they use to decontaminate radiation?
You can still use tap water for decontamination. Any radioactive material that gets into surface water or ground water sources will be diluted to very low levels by the water and will be safe to use for washing skin, hair, and clothing.
How is the victim of nerve agent exposure presenting?
How is the victim of nerve agent exposure presenting with convulsions classified? Eyes are the most vulnerable to this agent due to their thin, moist, warm mucosa. Acute Radiation Syndrome results from high-level external exposure to ionizing radiation.
What type of laboratory test S would not be conducted if you suspect a patient has contracted plague?
Gas Chromatography-Mass Spectrometry would NOT be conducted if you suspect a patient has contracted plague. This answer has been confirmed as correct and helpful.
Which of the following bacterial disease is contagious?
Whooping cough is the most contagious bacterial infection.
What form of ionizing radiation can penetrate deeply?
Ionizing radiation is relatively high in energy, and when it collides with an atom, it can completely remove an electron to form a positively charged ion that can damage biological tissues. Alpha particles do not penetrate very far into matter, whereas γ rays penetrate more deeply.
Is there anything radiation Cannot penetrate?
Despite their ability to penetrate other materials, in general, neither gamma rays nor x-rays have the ability to make anything radioactive. Several feet of concrete or a few inches of dense material (such as lead) are able to block these types of radiation.
Which is the most dangerous radiation at a distance?
Gamma rays are the most harmful external hazard. Beta particles can partially penetrate skin, causing “beta burns”. Alpha particles cannot penetrate intact skin. Gamma and x-rays can pass through a person damaging cells in their path.
What is the most penetrating type of radiation?
Gamma rays
What stops different types of radiation?
The only way to stop them is with large quantities of water or other materials made of very light atoms. On the other hand, an alpha particle, because it’s very heavy and has a very large charge, doesn’t go very far at all. This means an alpha particle can’t even get through a sheet of paper.
