Types and SOP for Portable Fire Extinguishers Used in the Pharmaceutical Industry

The pharmaceutical industry is highly regulated, with safety being a top priority due to the handling of chemicals, flammable substances, and sensitive equipment. One essential component of workplace safety is the proper use of portable fire extinguishers. These devices play a critical role in preventing small fires from escalating into significant hazards, protecting personnel, equipment, and facilities. In this article, we’ll explore the types of portable fire extinguishers commonly used in the pharmaceutical industry and outline a detailed Standard Operating Procedure (SOP) for their usage, maintenance, and storage.

Importance of Fire Safety in the Pharmaceutical Industry

Pharmaceutical facilities are high-risk environments where fires can occur due to the following factors:

• Handling of flammable chemicals like solvents and alcohol-based solutions.
• Use of high-temperature equipment such as autoclaves and dryers.
• Electrical equipment malfunctions or short circuits.

Given these risks, having the correct type of portable fire extinguisher readily available and ensuring proper training for personnel is critical to maintaining workplace safety and regulatory compliance.

Types of Portable Fire Extinguishers in the Pharmaceutical Industry

Different types of fire extinguishers are designed to tackle specific classes of fire. Understanding the types available and their suitability for particular fire hazards is crucial in the pharmaceutical setting.

1. Water Fire Extinguishers

• Class of Fire: Class A (Fires involving combustible materials like paper, wood, and fabric).
• Description: These extinguishers contain water under pressure and are ideal for tackling ordinary fires involving non-electrical combustible materials.
• Use in Pharmaceuticals: Limited use, as most fires in pharmaceutical facilities involve chemicals or electrical equipment.

2. Carbon Dioxide (CO₂) Fire Extinguishers

• Class of Fire: Class B (Flammable liquids) and Class C (Electrical fires).
• Description: CO₂ extinguishers work by displacing oxygen and cooling the fire, making them ideal for environments with electrical equipment or flammable liquids.
• Use in Pharmaceuticals: Widely used for fires in laboratories, manufacturing areas, and storage facilities housing solvents or electronic equipment.

3. Dry Powder Fire Extinguishers

• Class of Fire: Class A, B, and C.
• Description: These versatile extinguishers use a dry chemical powder to smother fires by interrupting the chemical reaction.
• Use in Pharmaceuticals: Effective for tackling a wide range of fires, including those involving flammable chemicals or gases, but less suitable for enclosed areas due to the mess they create.

4. Foam Fire Extinguishers

• Class of Fire: Class A and B.
• Description: Foam extinguishers create a barrier on the surface of flammable liquids, preventing oxygen from fueling the fire.
• Use in Pharmaceuticals: Suitable for fires involving alcohol-based solutions or flammable liquids used in production processes.

5. Specialized Chemical Fire Extinguishers

• Class of Fire: Class D (Fires involving combustible metals like magnesium, lithium, or sodium).
• Description: These extinguishers contain specific chemicals to address metal fires, which are difficult to extinguish with traditional methods.
• Use in Pharmaceuticals: Primarily used in facilities dealing with specialized metal-based compounds or manufacturing equipment.

Standard Operating Procedure (SOP) for Portable Fire Extinguishers

An effective SOP for portable fire extinguishers ensures that employees are well-prepared to handle fire emergencies while maintaining safety and compliance with regulations. Below is a step-by-step SOP tailored for the pharmaceutical industry.

1. Scope

This SOP applies to all personnel in the pharmaceutical facility responsible for the use, maintenance, and inspection of portable fire extinguishers.

2. Objectives

• To provide guidelines on the proper selection, use, and maintenance of fire extinguishers.
• To ensure compliance with fire safety regulations and industry standards.
• To minimize the risk of fire-related accidents and damages.

3. Responsibilities

• Safety Officer: Oversee the implementation of the SOP and ensure compliance.
• Employees: Follow the guidelines for fire extinguisher use and participate in training sessions.
• Maintenance Team: Conduct regular inspections and servicing of fire extinguishers.

4. Procedure

A. Selection and Placement

1. Identify Fire Risks:
   • Conduct a risk assessment to identify potential fire hazards in different areas (e.g., labs, storage, manufacturing zones).
   • Select fire extinguishers based on the class of fire likely to occur.
2. Placement Guidelines:
   • Install fire extinguishers at accessible locations, near fire-prone areas, and along evacuation routes.
   • Ensure extinguishers are mounted on walls or stands at a height of 3–5 feet for easy access.
   • Mark the locations with clear signage.

B. Usage Instructions

1. Assess the Situation:
   • Determine whether it is safe to use a fire extinguisher (e.g., small, contained fire with no toxic fumes).
   • Alert nearby personnel and raise the fire alarm.
2. Follow the PASS Technique:
   • Pull the pin to break the tamper seal.
   • Aim the nozzle at the base of the fire.
   • Squeeze the handle to release the extinguishing agent.
   • Sweep the nozzle from side to side until the fire is extinguished.
3. Evacuate if Necessary:
   • If the fire cannot be controlled, evacuate the area immediately and wait for emergency responders.

C. Inspection and Maintenance

1. Daily Checks:
   • Inspect fire extinguishers for visible damage, corrosion, or tampering.
   • Ensure the pressure gauge indicates the correct pressure level.
2. Monthly Inspections:
   • Verify that extinguishers are in their designated locations and accessible.
   • Check for expired inspection tags or missing pins.
3. Annual Servicing:
   • Engage certified professionals to conduct a thorough inspection and servicing.
   • Replace damaged or expired extinguishers.
4. Hydrostatic Testing:
   • Conduct hydrostatic testing every 5–12 years, depending on the type of extinguisher, to check for cylinder integrity.

D. Employee Training

1. Initial Training:
   • Provide fire safety training during onboarding, including hands-on sessions for using extinguishers.
2. Periodic Drills:
   • Conduct fire drills every six months to reinforce safety protocols and improve response times.
3. Documentation:
   • Maintain records of training sessions, inspections, and maintenance activities for regulatory compliance.

E. Emergency Protocols

1. Contact Emergency Services:
   • Dial the designated emergency number and provide details about the fire.
   • Assign a team member to guide responders to the location.
2. Post-Fire Assessment:
   • Investigate the cause of the fire and document findings.
   • Review and update fire safety measures based on lessons learned.

Compliance with Fire Safety Standards

Pharmaceutical companies must comply with local and international fire safety regulations, such as:

• NFPA Standards: The National Fire Protection Association (NFPA) provides guidelines for fire extinguishers, including placement, maintenance, and training.
• OSHA Regulations: The Occupational Safety and Health Administration mandates fire safety measures to protect employees.
• ISO Standards: ISO 45001 emphasizes workplace safety, including fire hazard management.

Adhering to these standards not only ensures safety but also minimizes liabilities during audits and inspections.

Conclusion

Fire safety is an essential aspect of pharmaceutical operations, where the risks of fire incidents are heightened by the presence of flammable substances and electrical equipment. Understanding the types of portable fire extinguishers and implementing a robust SOP for their use and maintenance can significantly reduce fire hazards.

By fostering a culture of fire safety through regular training, routine inspections, and adherence to regulations, pharmaceutical companies can protect their assets, employees, and the environment. A proactive approach to fire prevention and preparedness is not just a compliance requirement—it is a critical investment in safeguarding lives and business continuity.
