Standard Operating Procedure: Hospital Laundry Management

This Standard Operating Procedure (SOP) outlines the mandatory protocols for the collection, handling, processing, and distribution of hospital linens. Given the high-risk nature of clinical environments, this SOP is designed to prevent cross-contamination, ensure the eradication of pathogens through thermal and chemical disinfection, and maintain the highest standards of hygiene for patient safety and infection control.

1. Collection and Containment

• Segregation at Source: Sort linens into "General," "Infected/Contaminated," and "Soiled" (heavily stained with blood or body fluids) at the point of use.
• Use of Appropriate Bags: Place infected linens directly into water-soluble bags, followed by a color-coded, leak-proof exterior bag (e.g., Red for biohazardous/contaminated).
• No Sorting Policy: Do not shake or manually sort linens in patient care areas to prevent the aerosolization of pathogens.
• Transport Logistics: Utilize designated, closed-trolley carts for transport. Ensure trolleys are disinfected after every shift.

2. Processing and Disinfection

• Personal Protective Equipment (PPE): Laundry staff must wear fluid-resistant gowns, heavy-duty gloves, face shields, and masks during the sorting and loading phases.
• Automated Dosing: Ensure chemical dispensing systems are calibrated for the specific thermal requirements (minimum 71°C/160°F for at least 25 minutes) for chemical-thermal disinfection.
• Loading Protocols: Do not overfill industrial washers. Overloading prevents proper agitation and chemical penetration.
• Drying and Finishing: Ensure cycles are set to complete dryness. Moisture in stored linens facilitates fungal and bacterial growth.
• Ironing/Pressing: Utilize high-heat pressing for garments where required, as this provides an additional thermal barrier against residual microorganisms.

3. Storage and Distribution

• Clean-Dirty Separation: Maintain strict physical separation between the soiled laundry processing area and the clean linen storage area (negative air pressure in soiled areas, positive in clean).
• Storage Environment: Store clean linens in a climate-controlled, dust-free environment, at least 6 inches off the floor and 18 inches from sprinkler heads.
• Inventory Rotation: Adhere to the "First-In, First-Out" (FIFO) principle to prevent the stagnation of stock.
• Protected Transport: Use clean, covered carts to deliver linens to wards. Never use the same carts for both soiled and clean linens without rigorous disinfection cycles.

Pro Tips & Pitfalls

• Pitfall - Cross-Contamination: The most common failure point is "Clean-Dirty" overlap. Use different colored floor markings for paths taken by soiled vs. clean carts.
• Pro Tip - Chemical Monitoring: Maintain a daily log of water temperature and pH levels. Many detergents lose effectiveness if the water hardness or pH is not balanced correctly.
• Pro Tip - Sharp Detection: Implement a mandatory "check for sharps" step before loading. Even a small needle left in a sheet can cause a significant needlestick injury to laundry staff.

Frequently Asked Questions

Q: Can linens from COVID-19 or highly infectious wards be washed with standard patient linens? A: No. Any linen identified as highly infectious must be treated as biohazardous and processed separately using validated high-temperature cycles or validated chemical disinfectants.

Q: How often should the laundry transport carts be cleaned? A: Transport carts must be wiped down with a hospital-grade disinfectant after every delivery cycle. A deep-cleaning schedule (using a cart-wash machine or high-pressure spray) should be implemented weekly.

Q: What should be done if an employee suffers a needlestick injury while sorting laundry? A: The employee must immediately stop work, wash the affected area with soap and water, report the incident to the Occupational Health Department, and complete an Incident Report form as per the hospital's Bloodborne Pathogen Exposure Plan.
