How to handle contaminated laundry?
The laundry process starts with the removal of used or contaminated textiles, fabrics, and/or clothing from the areas where such contamination occurred, including but not limited to patients’ rooms, surgical/operating areas, and laboratories. Handling contaminated laundry with a minimum of agitation can help prevent the generation of potentially contaminated lint aerosols in patient-care areas. 967, 1259 Sorting or rinsing contaminated laundry at the location where contamination occurred is prohibited by OSHA. 967 Contaminated textiles and fabrics are placed into bags or other appropriate containment in this location; these bags are then securely tied or otherwise closed to prevent leakage. 967 Single bags of sufficient tensile strength are adequate for containing laundry, but leak-resistant containment is needed if the laundry is wet and capable of soaking through a cloth bag. 1264 Bags containing contaminated laundry must be clearly identified with labels, color-coding, or other methods so that health-care workers handle these items safely, regardless of whether the laundry is transported within the facility or destined for transport to an off-site laundry service. 967
How are contaminated textiles transported?
Clean/sterile and contaminated textiles should be transported from the laundry to the health-care facility in vehicles (e.g., trucks, vans, and carts) that allow for separation of clean/sterile and contaminated items. Clean/sterile textiles and contaminated textiles may be transported in the same vehicle, provided that the use of physical barriers and/or space separation can be verified to be effective in protecting the clean/sterile items from contamination. Clean, uncovered/unwrapped textiles stored in a clean location for short periods of time (e.g., uncovered and used within a few hours) have not been demonstrated to contribute to increased levels of health-care acquired infection. Such textiles can be stored in convenient places for use during the provision of care, provided that the textiles can be maintained dry and free from soil and body-substance contamination.
How to transport contaminated clothing?
Contaminated textiles and fabrics in bags can be transported by cart or chute. 1258, 1262 Laundry chutes require proper design, maintenance, and use, because the piston-like action of a laundry bag traveling in the chute can propel airborne microbial contaminants throughout the facility. 1267–1269 Laundry chutes should be maintained under negative air pressure to prevent the spread of microorganisms from floor to floor. Loose, contaminated pieces of laundry should not be tossed into chutes, and laundry bags should be closed or otherwise secured to prevent the contents from falling out into the chute. 1270 Health-care facilities should determine the point in the laundry process at which textiles and fabrics should be sorted. Sorting after washing minimizes the exposure of laundry workers to infective material in soiled fabrics, reduces airborne microbial contamination in the laundry area, and helps to prevent potential percutaneous injuries to personnel. 1271 Sorting laundry before washing protects both the machinery and fabrics from hard objects (e.g., needles, syringes, and patients’ property) and reduces the potential for recontamination of clean textiles. 1272 Sorting laundry before washing also allows for customization of laundry formulas based on the mix of products in the system and types of soils encountered. Additionally, if work flow allows, increasing the amount of segregation by specific product types will usually yield the greatest amount of work efficiency during inspection, folding, and pack-making operations. 1253 Protective apparel for the workers and appropriate ventilation can minimize these exposures. 967, 1258–1260 Gloves used for the task of sorting laundry should be of sufficient thickness to minimize sharps injuries. 967 Employee safety personnel and industrial hygienists can help to determine the appropriate glove choice.
What are the microorganisms in clothing?
Contaminated textiles and fabrics often contain high numbers of microorganisms from body substances, including blood, skin, stool, urine, vomitus, and other body tissues and fluids. When textiles are heavily contaminated with potentially infective body substances, they can contain bacterial loads of 10 6 –10 8 CFU/100 cm 2 of fabric. 1247 Disease transmission attributed to health-care laundry has involved contaminated fabrics that were handled inappropriately (i.e., the shaking of soiled linens). Bacteria ( Salmonella spp., Bacillus cereus ), viruses (hepatitis B virus [HBV]), fungi ( Microsporum canis ), and ectoparasites (scabies) presumably have been transmitted from contaminated textiles and fabrics to workers via
Where should clean/sterile and contaminated textiles be transported?
Clean/sterile and contaminated textiles should be transported from the laundry to the health-care facility in vehicles (e.g., trucks, vans, and carts) that allow for separation of clean/sterile and contaminated items.
What is wrapping textiles?

How does laundry affect the environment?
Laundry, a regular and mundane chore, has a significant environmental impact. With the technological advances of modern appliances and the introduction of environmentally friendly scent-free products over the past decade, it is easier than ever to "green" your laundry practices. Here are some facts about laundry: 1 The average residential washing machine uses about 41 gallons of water per load. 2 A clothes dryer is responsible for approximately 6 percent of the average home’s energy use. 3 Commercial washing machines vary widely, using an average of 34.74 thousand gallons of water and up to 910 kWh of electricity per year. 4 Scented liquid laundry detergent and dryer sheets contain hazardous chemicals and emit volatile organic compounds (VOCs), two of which are classified as carcinogens by the Environmental Protection Agency.

How much energy does a commercial washer save?
The commercial laundry sector in particular has the potential to "yield significant savings" by transitioning to ENERGY STAR commercial washers since market penetration of ENERGY STAR washers is estimated at only 32%. A 2013 report by the American Council for an Energy-Efficient Economy and the Natural Resources Defense Council Water suggests that upgrades of commercial washing machines can result in savings of 9.3 to 29.6 gallons of water and reductions in dryer use can save 25,000 to 38,000 BTUs per wash cycle.

Week 29
Last week I took a long, hard look at my clothes shopping habit and fast fashion's negative environmental impact. So, naturally, it's time to delve into how I launder my clothing.
Water
According to Energy Star, conventional top-loading washing machines use around 20 gallons of water per load. Since the average American family does about 300 loads of laundry every year, your washing machine is responsible for roughly 6,000 gallons of water waste every year.
Electricity
In Week 27, I learned that the electricity system is the second largest contributor to greenhouse gas emissions. Both washing machines and dryers require electricity to run and and they account for approximately 6% of household electricity usage. The heating element of most dryers use 4,000-6,000 watts of energy.
Detergent
Despite that questionable trend of kids eating Tide Pods, conventional laundry detergent contains all sorts of chemical ingredients, many of which are toxic to humans, pets, and aquatic life. The environmental impact of these ingredients is too extensive to cover in this post, so please read this article by Green Matters for further explanation.
Dryer Sheets
Conventional dryer sheets are made of nonwoven polyester which is a form of plastic. There has been a bit of controversy surrounding the toxicity of chemicals used in dryer sheets, but dryer sheets can leave a film on the filter that reduces air flow and, over time, can affect the performance of the motor.
Microplastics from Synthetic Fabric
Synthetic materials like rayon, acryclic, polyester, and nylon make up roughly 60% of clothing material worldwide, and they are all made of plastic. When manufactured, worn, and laundered, they shed tiny, plastic microfibers, and contribute 35% of the microplastics polluting our oceans .
