Are there any requirements for materials for clean room supplies and consumables?

First of all, in order to ensure the cleanliness of the clean workshop (clean room), unnecessary items are not allowed to move into the clean room. On the one hand, these items will affect the stability of indoor air flow, and at the same time increase the possibility of dust accumulation and hair growth in clean rooms. Items that must be moved into the clean room should be as few as possible and placed in places with little or no impact.

Secondly, in order to reduce the amount of dust in the clean room, products generally use stainless steel, steel plate electrostatic spraying materials or other materials with small dust (products such as cartons are prohibited from being brought in). The article is simple in structure and does not take the form of edges and corners. For example, the surface of the table is made of less dusty materials, without drawers, shelves and enclosures, and rubber covers are added to the feet. The back of the chair should be vertical, without handrails, with proper sitting height and rubber feet.

You can't use dusty paper for recording in a clean room, but use paper with a little dust. You can't use pencils, erasers or pens, only plastic ballpoint pens. Clean rooms generally do not have billboards and message boards. When necessary, the bulletin board of clean room should be wiped with whiteboard, insulating pen and special rubber.

3. Workers' cigarettes, matches, lighters, drinks and chewing gum, precious stones, decorations, cosmetics, toilet paper, handkerchiefs, wallets, keys, watches and notebooks are not allowed to be brought into the clean room. All materials, instrument spare parts, determination and other items that are not purified according to regulations, as well as unauthorized radioactive substances, are not allowed to enter the clean room.
