When testing the static eliminator, the operator should take electrostatic protection measures, such as wearing anti-static clothes, anti-static caps, anti-static shoes, etc. to ensure that the human body is grounded. The compressed air source of the static eliminator should be clean, dry, free of dust, grease, moisture, etc. During testing, various parameters of the test environment should be recorded, such as temperature, humidity, air flow rate, air pressure or air flow, and environmental cleanroom cleanliness. Matters Need Attention 1:There should be no large metal conductors or metal grounding bodies around the static eliminator and testing equipment. 2:There should be no other static eliminators, static generators, high-voltage power supplies, power spray, high-voltage power transmission, and live equipment around the static eliminator and the testing instrument. 3:There should be no statically charged insulating objects or static sources around the static eliminator and testing equipment. 4:There should be no obstacles that hinder the air flow between the static eliminator and the testing instrument. The testing instrument and static eliminator (if there is a ground terminal) should be well grounded. Before the testing instrument is used for testing, it should be cleared or adjusted. Testing environment requirements Test temperature and humidity: 20-26℃, 12±3%RH or 50±5%RH. (When the technical contract has special requirements for the test temperature and humidity of the static eliminator, it shall be executed according to the corresponding technical contract) There must no turbulent air flow, electrostatic field, and interference electromagnetic field within a radius of 1.5m around the static eliminator or the flat panel testing instrument.

When working in a cleanroom it is important to maintain a pristine, contaminant free, environment. The less well-kept a room is then the more likely it is harboring pollutants, which can distort the results of the work taking place within the room. Since these rooms are built to prevent contamination to an exceedingly small degree, not implementing a regular maintenance schedule can fundamentally interfere with the functionality of the room over a period of time. The best way to ensure your work space is pristine, is by creating a regular maintenance routine that is specific to your critical environment’s needs. In this post we’ll take a look at why exactly this is so important, some ways to establish a regular maintenance schedule, and provide a general outline for thorough cleansing of all equipment within a cleanroom. Why is maintenance so important? Regular maintenance is vital to cleanrooms because without a maintenance plan, contaminants will accumulate and put all work within the environment at risk of being compromised. It's not just limited to physically cleaning a room, but also ensuring reliability and efficiency of equipment day to day. A thorough maintenance plan will reduce the potential amount of unplanned downtime due to breakdowns and faults. Preventative measures reduce this potential through regular checks of the equipment and the room itself. A regular plan prevents the buildup of dust, vapors, and other airborne particles which equipment and products are sensitive to. Not only is creating a schedule of regular maintenance for a room important, but so is the exact way that it occurs. In fact, even wiping up a mess improperly can be a potential source of contamination. We recommend using lint-free, disposable mop heads, non-shedding wipes, plastic or stainless steel buckets, as well as HEPA filter vacuums while cleaning your room. Always make sure that you have the specified equipment for your room as well. Improperly matched products in rooms can result in the introduction of microorganisms into your environment, effectively contaminating your cleanroom. Day to Day Maintenance The most effective way to ensure your room maintains its day to day cleanliness is to establish daily maintenance routines. Regular routines, while working, serve to clear the room from particles introduced by cleanroom staff. Every room has different requirements, but the following are some ways to control the human component. Before establishing guidelines in your own cleanroom, first make sure that they are appropriate for your specific requirements. The following rules have been assembled by Roger McFadden, Senior Scientists for Staples Inc, and are appropriate for a Class 1000 cleanroom.

Many industries require personal protective equipment (PPE) to safely and efficiently perform tasks. Products like disposable gloves are valuable for numerous applications, protecting both the wearer and the patients or products they handle. There are various glove materials available on the market, so it’s crucial to understand the benefits and limitations of each product before supplying them to workers. With its high durability, greater chemical resistance, no risk of latex allergies and other advantages, nitrile has become a suitable material for medical and industrial gloves across the country. Professionals use nitrile gloves in various sectors as a go-to disposable glove. Here’s a look at everything to know about nitrile. What Is Nitrile? Nitrile rubber, also called Buna-N or NBR, is a synthetic rubber copolymer derived from acrylonitrile (ACN) and butadiene molecules. Depending on its composition, nitrile rubber can vary in its chemical resistance and physical properties. More acrylonitrile will increase the rubber’s resistance to swelling from oil and produce a stronger material. Nitrile rubber with less acrylonitrile will be more flexible. Typically, people who choose nitrile rubber opt for variations with inferior flexibility to boost its other qualities. Nitrile is a versatile elastomer, widely used for its general properties like high tensile strength, high puncture resistance, chemical and oil resistance, hypoallergenic qualities and more. Gloves constructed from nitrile can protect against numerous hazards in medical and industrial applications. Nitrile’s versatility allows for the construction of both heavy-duty and tactile-focused synthetic rubber gloves. Nitrile gloves are available in multiple styles, including general-purpose, examination, sterile, non-sterile and chemo-related options. Nitrile Glove Specifications Disposable nitrile gloves intended for protective purposes must comply with various specifications for safety and effectiveness. Workplaces need to supply properly tested and FDA-certified products to their staff members. Evaluate the usability of each glove type to determine which material will best suit your working requirements. Base the benefits and limitations of different protective gloves on their performance in the following categories: Puncture resistance and durability Chemical resistance Comfort and flexibility Tactile sensitivity Level of risk for a Type 1 allergic reaction Cost-effective

When we do cleaning in a clean room, we often encounter some work that is difficult to standardize. At this time, such non-standard or non-consistent operations will cause potential risks to the effect of cleaning work. Does the following situation sound familiar to you? The user takes out the dry wipe and sprays the cleaning agent from the spray alcohol bottle on the dry wipe. At this time, how to control this process? Where to spray on the wiper? How much spray is appropriate? How did you wipe it after spraying? Do different users operate the same way? Do these all need to be standardized? When a user attempts to spray a cleanser from a spray alcohol bottle onto a dry wipe, it is often difficult to know exactly how much liquid to add, because wearing cleanroom gloves reduces the tactile feedback of the fingers, making it impossible to know exactly how wet does the cleanroom cloths. As a result, the operator tends to use more liquid than is actually required, and in many cases the wipe becomes very saturated. Excessive pre-wetting affects the cleaning process and can only carry contaminants from one area to another, not remove contaminants. The cleaning work of the clean room must be consistent, so in order to achieve the consistency of the cleaning effect, it is necessary to trace the consistency of the cleaning process, but the usage habits of different users are different. Some people may finish spraying the cleaning agent, just pick up a whole cloth and start wiping, and some people will also perform standard wiping and folding steps, and then wipe after folding in half. Of course, the more difficult and uncontrollable thing is to spray more and less. If the user is required to fix the number of sprays, it seems too difficult.

The objective of an environmentally controlled cleanroom is to provide a contamination-free space in which to manufacture and/or test products that cannot tolerate even the smallest particles. Cleanroom classification includes the clean room wipers ratings range from 1 to 100,000 according to the number and size of particles permitted per volume of air. However, cleanrooms specialising in semiconductor, microelectronics and medical device/pharmaceutical manufacturing are among the most stringent. Such facilities require implementation of specific processes to reduce all sources of contamination. This also means using products within the cleanroom that are designed to meet specific cleanliness standards. Contamination can occur unexpectedly without any obvious indication of its origin. It can come from the materials and equipment used for manufacturing, the people in the cleanroom and even consumables like tapes or other paper-based products that shed particulates. Outlined below are five hidden causes of contamination that can compromise a facility's cleanroom standards as well as approaches to minimise these sources' impact. People Perhaps the most well known source, most airborne particles from people migrate out of their cleanroom garments. Using improper cleanroom garments, not following proper gowning protocol, gowning insufficiently for a particular facility class or going too long between changing suits, smocks, other garments or floor mats can all increase particle levels in a cleanroom. Particles can escape from even the smallest defects in cleanroom garments, such as tears, loose fabric, etc. Consistent use of cleanroom-optimised cuff sealing tape is one simple way to minimise opportunities for contamination. Labels and Tapes Often overlooked in terms of contamination potential, traditional labels and tapes are an unexpected source of cleanroom contamination, especially if they are made from paper, have paper cores and/or have adhesives that outgas or leave behind sticky residue. Let's examine these issues one at a time. Cores: Most tape products are manufactured on cardboard cores, which tend to particulate. To prevent particulation from the core, use tape rolls that have plastic cores with smooth finishes. This is important because plastic burrs and sharp edges could cut through cleanroom gloves or bags, exposing the cleanroom to additional sources of contamination. Backings and Liners: For other tapes and labels, paper backings or face stocks also cause particulation in the cleanroom. Further, release liners and paper tend to leave behind particulates that could contaminate a cleanroom. Using synthetic materials for these uses eliminates particle generation. Packaging: Beyond the use of clean room paper materials in tapes and labels, contamination can even be present in the packaging itself (printed bags, electrostatic-discharge bags, and single bagged items). For maximum protection, items should be double-bagged and properly de-bagg...
