First Action for Chemical Spill Exposure: Decontamination Protocol

The first action when a client is exposed to a chemical spill must be immediate decontamination before entering the healthcare facility to prevent secondary contamination and minimize health risks to the patient and healthcare workers. 1, 2

Rationale for Immediate Decontamination

• Decontamination directly benefits patients' health by saving lives and reducing toxicity severity by terminating further exposure and preventing systemic absorption 2
• Chemical toxicity may manifest rapidly (minutes to hours after exposure), making immediate decontamination critical 2
• Contaminated victims often self-refer to healthcare facilities and attempt to access clean areas in pursuit of treatment, potentially contaminating staff and facilities 1
• Secondary exposure of medical staff to chemical agents has been documented when treatment was provided inside closed rooms without proper decontamination 1

Decontamination Protocol

Initial Steps

• Remove all contaminated clothing, shoes, and jewelry immediately to prevent chemicals from being trapped against skin 3
• For dry chemicals, brush off powder before irrigating with water 3
• Irrigate affected areas with copious amounts of running water for at least 15 minutes 3
• Approximately 70-95% of decontamination can be accomplished by removing outer clothing and shoes 1

Location and Process

• Decontamination should be completed in the field or at least outside the medical center 1
• Healthcare facilities should have decontamination capabilities that can be operational within minutes 1
• Separate decontamination pathways should be established for different exposure risk groups to minimize cross-contamination 1

Staff Protection During Decontamination

• Healthcare staff must wear adequate protective equipment when assisting with decontamination 1
• Level C personal protective equipment (splash suits, gloves, boots, air-purifying respirators) should be available for healthcare facility decontamination teams 1
• Ordinary surgical masks and latex gloves do not provide adequate protection from toxic vapors 1

After Decontamination

• Once properly decontaminated, patients can receive further medical interventions such as:
  • Oxygen therapy
  • IV access
  • Administration of specific antidotes (if identified and available) 1
• Monitor for respiratory or systemic symptoms that would require emergency medical attention 3

Common Pitfalls to Avoid

• Delaying decontamination while waiting for specialized equipment 4
• Using alcohol-based products on damaged skin as they may cause further irritation 4
• Allowing contaminated individuals to enter clean areas of healthcare facilities 1
• Failing to protect healthcare workers with appropriate personal protective equipment 1
• Neglecting to wash exposed jewelry, glasses, and other personal items 1

By following this protocol, healthcare providers can minimize the health impacts of chemical exposure while protecting themselves and their facilities from secondary contamination.
