Understanding Disposable Gloves

Disposable gloves serve as crucial single-use barriers across diverse fields, reducing exposure to blood, body fluids, chemicals, and grime. Widely utilized in healthcare, laboratories, food preparation, and trades, these gloves conform to OSHA's directive for hand protection according to 29 CFR 1910.138. In food handling, gloves form barriers when dealing with ready-to-eat items, complying with FDA's Food Code. Dentists, phlebotomists, and cleaning crews rely heavily on these gloves to curb cross-contamination risks.

Varieties include:

• Nitrile: Ideal for splash resistance and puncture resilience, especially where latex allergies are a concern. Consult FDA's medical gloves overview.
• Latex: Known for superb elasticity and tactile sensitivity, suitable for clinical applications, but beware of potential allergenicity, adhering to OSHA PPE regulations.
• Vinyl: Cost-effective for brief, low-risk tasks, offering limited resistance to solvents and elasticity.
• Polyethylene/TPE: Effective for loose-fitting food handling but unsuitable for precision work or prolonged exposure.

Designed for single use, these gloves maintain integrity only for specific tasks or patient interactions, becoming unsuitable upon reprocessing. Selection should consider size, cuff length, and thickness relative to exposure time, splash risk, and dexterity needs, aligning material choice to hazards per OSHA hand protection guidelines. To streamline infection-control, CDC offers guidelines on donning and doffing processes found in the HAI PPE steps poster (CDC PDF).

Gloves degrade over time due to ozone, oils, certain solvents, and UV exposure. Storing in a cool, dry, sunlight-absent environment enhances their longevity. However, improper use can pose risks, leading to a false sense of security or spreading contamination if not changed between tasks, alongside consistent hand hygiene practices.

Risks of Reusing Disposable Gloves

Single-use gloves play a critical role in workplace safety but are not advisable for reuse. The Occupational Safety and Health Administration (OSHA) clearly outlines in its Bloodborne Pathogens standard that disposable protective gear should neither be washed nor decontaminated for reuse. This mandate stems from concerns over the loss of barrier integrity and potential contamination hazards per 29 CFR 1910.1030(d)(3)(ix). Similarly, the Food and Drug Administration (FDA) categorizes these medical examination products as single-use devices, with labeling and performance standards designed for one-time wear (FDA: Medical Gloves).

Several risks arise when previously used hand coverings undergo reuse:

• Micro-perforations: Small defects appear during donning, doffing, and task performances. These micro-perforations, invisible to the naked eye, allow fluids and pathogens through when pressure is applied.
• Chemical degradation: Attempts to sanitize with alcohols, chlorine, or UV light chemically degrade materials, affecting fit and performance adversely. CDC/NIOSH advises against such practices (CDC/NIOSH).
• Residual contamination: After tasks, lingering contaminants on surfaces become problematic. Handling contaminates interiors, transferring microbes upon redonning.
• Elastic loss: Repeated use diminishes elastic strength, increasing rupture risks.
• Poor fit: Glove materials lose their mold after initial use. This worsens snagging and puncture potential around seams and fingertips.
• False confidence: Reuse engenders complacency, undermining strict adherence to handwashing and change-out routines.

Nitrile options typically exhibit superior chemical and puncture resistance. Nonetheless, exposure to disinfectants and multiple uses degrade their tensile properties and elongation capabilities. Even top-tier nitrile variations, once removed, should be replaced immediately when involved in patient care, food handling, or contamination-sensitive operations.

For professionals in trades, laboratories, and clinics, effective safety practices hinge on selecting right-sized, task-specific products, maintaining adequate replacement stock, and adhering to defined disposal triggers. These triggers include visible damage, potential contamination, exposure to bodily fluids or hazardous chemicals, and compliance with site-specific, time-based protocols. Items designated as single-use must adhere strictly to these guidelines under OSHA, FDA, and CDC directives.

FAQ on Disposable Gloves

Washing and Reusing Disposable Gloves
Briefly put, disposable gloves should not be washed. Doing so can degrade materials such as nitrile or latex, causing microtears and defeating the barrier's effectiveness. Both FDA and CDC emphasize that gloves subjected to washing or alcohol-based rubs lose their protective function.

Why Reusing the Same Gloves is a Bad Idea
Using the same pair of disposable gloves multiple times raises contamination risks considerably. Oils, solvents, or disinfectants compromise the material's integrity, altering fit and texture. Reusing undermines effective hand hygiene protocols, potentially cross-contaminating surfaces. OSHA 1910.138 regulations highlight the importance of single-use protection provided by a well-executed Employer PPE program.

How Many Times Disposable Gloves Can Be Used
Disposable gloves are designed for single-task use. Replace them after contact with blood, bodily fluids, between patients, or after interacting with contaminated surfaces. Adhering to CDC's Standard Precautions promotes appropriate glove use, alongside proper hand hygiene.

Washing Gloves for Reuse with the Same Patient
Even when dealing with the same patient, gloves should not undergo washing for reuse. Instead, employ proper hand hygiene practices, followed by donning a new pair for subsequent care activities. During shortages, extended use was recommended over reuse, yet washing remained unadvised. For effective protection, each pair should be discarded after a single use, ensuring safety is upheld.
