The considerations that responders would have to keep in mind at this scene

  • The responders should bear in mind that the scene could be a potential danger zone. As such, they need to ensure their safety before assessing the situation. For instance, one may wear a face shield to protect themselves from inhaling the chemical odors.
  • One should also consider time. Acting fast would ensure that the person who was reported ill is saved and receives medical treatment as soon as possible.
  • Additionally, responders should keep in mind the need to have adequate and right tools. This facilitates proper assessment of the scene.

The actions of first arriving units

  • First arriving officers should initially ensure their safety, that of other officers, as well as other people present in the scene. This involves making sure that there are no immediate threats that can render you and other individuals as victims. If CBRNE agents are involved, responders the suitable agency.
  • To protect oneself, an officer needs to use personal protection equipment (PPE). PPE is intended to safeguard an individual from harm that may result from contact with chemical, physical, radiological, and biological hazards (Fish et al., 2013).
  • Respiratory protection equipment such as lightweight respirators is one of the PPE that responders in this situation may need. This is to protect them from harm that may result from breathing in contaminated air.
  • They may also use eye and face PPE such as safety glasses or visors. This would shield them from any chemical splashes that may come out of the structure.
  • The responders may also require hand and foot protection apparatus such as gloves and boots respectively. This may protect them from coming into contact with the unusual debris identified in the scene.
  • After ensuring safety, the first-arriving units should seek medical attention for the victims. If the individual initially reported as ill is still alive, they should be provided with immediate medical treatment. If there is a possibility for the victim to die, a dying declaration should be obtained.
  • While attending to the victims, care should be taken not to contaminate the scene (Fish et al., 2013). This ensures that possible physical evidence is not altered.
  • After that, is necessary for the initial responders to control and identify persons within the scene. By restricting their movement, one prevents physical evidence from being destroyed (Fish et al., 2013). Recognizing people enables the responders to know who are the suspects or witnesses.
  • Next, they should secure the scene by establishing physical barriers such as ropes or barrier tapes used in crime scenes, among others based on the area and type of crime. Setting up boundaries maintains the integrity of the situation.
  • The responders should then, allow the investigator(s) in charge to take control of the situation. They should brief the officer(s) about the scene.

Protocol for processing the crime scene

  • Interview individuals at the crime scene to come up with the case’s theory. The crime investigator(s) asks the first responders or witnesses about what supposedly took place, the nature of the wrongdoing, and how it was executed, among other questions (Maloney, Housman & Gardner, 2014).
  • The next procedure involves examining the situation to substantiate the developed theory. This can be achieved by identifying and marking evidence.
  • The crime scene expert(s) then photograph the scene including the evidence. This is done to obtain a pictorial appearance of everything as it was.
  • The fourth step involves creating a sketch. A sketch shows the arrangement of the victim and evidence within the scene (Maloney, Housman & Gardner, 2014).
  • After that, investigators process the crime scene. This involves gathering evidence for further examination and for use in court. For instance, the debris in this crime scene may be collected for testing in the crime laboratories.

Evidence preservation

  • Bodily fluids such as blood, urine, and semen just to mention a few should be preserved in items such as clean paper bags or envelopes and labeled appropriately (Lee & Pagliaro, 2013). One should avoid exposing body evidence to extreme heat or strong light.
  • Any Ammunition collected from the scene should be placed in paper containers. The opening of the container should be sealed using evidence tape.

How emergency responders can help to prevent and prepare for events involving CBRNE agents

  • Emergency responders should report to the relevant agencies as soon as possible if they identify any CBRNE material. Reporting early facilitates early analysis and mitigation measures to be applied to prevent a CBRNE occurrence.
  • Finding more information about a CBRNE even if it has already taken place. This helps to come up with risk mitigation measures.
  • They can also assist by setting up a focal control point (FCP) just in case a CBRNE event occurs. The FCP should be large and should be established based on the wind direction (Noll et al., 2014).
  • Communicate and cooperate with other departments and service providers. This makes it easy for emergency responders to obtain the equipment they need to attend to the situation.
  • Preventing more danger through decontamination. For instance, after identifying chemical contamination, one may remove the casualty’s clothes in a cautious manner.
