Various types of cleanroom clothing offer different levels of protection on all parts of the body. These can include bouffant caps, hair nets and hoods for the head, frocks or lab coats, aprons, sleeves and coveralls for the body, and shoe covers or boots for the feet. Goggles, gloves and face masks are also particularly important, not only for maintaining clean environments, but as PPE for workers as well. In some cleanrooms, respirators may also be necessary to ensure workers are not exposed to hazardous substances. The particles that can endanger these projects are hard to control, so equipment and workers in cleanrooms are held to the highest standards of cleanliness and performance.
A cleanroom is any given contained space where provisions are made to reduce particulate contamination and control other environmental parameters such as temperature, humidity and pressure. The key component is the High Efficiency Particulate Air filter that is used to trap particles that are 0.3 micron and larger in size. All of the air delivered to a cleanroom passes through HEPA filters, and in some cases where stringent cleanliness performance is necessary, Ultra Low Particulate Air filters are used. You can reuse smocks, coveralls, reusable shoe covers, and reusable caps or hoods, but exchange or have them cleaned periodically. A cleanroom is an environment, typically used in manufacturing or scientific research, that has a low level of environmental pollutants such as dust, airborne microbes, aerosol particles and chemical vapors.
Many types of industrially produced materials, such as semiconductors or other computer parts, can suffer damage when exposed to the most minute dust or dirt, so cleanrooms are designed to limit the dispersion of contaminants onto them. Additionally, many scientific research projects and experiments require sterile environments to prevent the introduction of outside random factors in order to ensure neutral and controlled results. Cleanroom clothing performs a critical protective function, it acts as abarrier between the person, the cleanroom and the product. To be effective Cleanroom clothing has to satisfy specific requirements but most of all it must act as a barrier. The material used is designed using continuous filament polyester that retains particles while allowing the fabric to breathe. This enables cleanroom clothing tofunction as a filter by preventing harmful contaminants from entering the cleanroom environment.
The standard also recommends changing all of this protective clothing with every single entry to the cleanroom. Wearing the protective clothing outside the sterilized environment can cause particles to adhere to it, which compromises the cleanliness of the clothing. Protective clothing is an essential Pharmaceutical Garments managed service piece of safety equipment meant to protect the wearer from various exposures. Whilecleanroom protective clothingguards the wearer against exposure to various hazards, it is also designed to prevent the cleanroom from becoming sullied by contaminants from the wearer’s clothing or person.
In the same way that cleanroom classifications specify the number and size of particles present per cubic meter of air, these classifications may also dictate which type of PPE is necessary for the employees working within them. Common PPE used in cleanroom environments include shoes, boots, shoe and boot covers, hairnets, beard covers, coveralls, face masks, frocks and lab coats, gowns, aprons, gloves, sleeves, and bouffant caps. These garments must be made with durable material that will withstand the length of time spent and type of tasks performed within a cleanroom.
