Standard Operating Procedure for Responding to Hazardous Material Exposure Incidents
1) Purpose
The purpose of this SOP is to establish clear guidelines for managing hazardous material exposure incidents, minimizing health risks, and ensuring timely and effective medical intervention for affected personnel.
2) Scope
This SOP applies to all employees, contractors, and visitors who may be exposed to hazardous materials, including chemicals, biological agents, or radioactive substances, during operations in laboratories, manufacturing units, and storage areas.
3) Responsibilities
- Emergency Response Team (ERT): Manage exposure incidents, provide first aid, and coordinate medical assistance.
- Supervisors: Ensure personnel are trained on hazard identification and response procedures.
- Safety Officers: Oversee the response to exposure incidents and ensure compliance with safety protocols.
- Exposed Personnel: Report exposure incidents immediately and follow instructions for decontamination and medical evaluation.
4) Procedure
4.1 Identifying Hazardous Material Exposure
- Types of Exposure:
- Skin or eye contact with hazardous materials (e.g., corrosive chemicals).
- Inhalation of toxic fumes, vapors, or dust.
- Ingestion of hazardous substances.
- Accidental injection of chemical or biological agents.
- Symptoms of Exposure:
- Burning or irritation on the skin or eyes.
- Difficulty breathing, coughing, or dizziness.
- Nausea, vomiting, or abdominal pain.
- Neurological symptoms such as confusion or loss of coordination.
- Immediate Reporting:
- Exposed personnel must notify their supervisor or the ERT immediately after the

incident.
4.2 Immediate Response to Exposure Incidents
- Skin Contact:
- Remove contaminated clothing immediately.
- Rinse the affected area with copious amounts of water for at least 15 minutes.
- Use soap to remove chemical residues, if safe to do so.
- Eye Contact:
- Flush eyes with water using an eyewash station for at least 15 minutes.
- Keep eyelids open to ensure thorough rinsing.
- Seek immediate medical attention after rinsing.
- Inhalation:
- Move the affected individual to fresh air immediately.
- Loosen tight clothing and ensure the airway is clear.
- Administer oxygen if breathing is difficult and personnel are trained to do so.
- Ingestion:
- Do not induce vomiting unless instructed by a medical professional or the material’s Safety Data Sheet (SDS).
- Rinse the mouth with water and provide small sips of water to the individual.
- Injection:
- Immediately clean the injection site with soap and water.
- Cover the area with a sterile dressing and seek medical attention.
