防護服從“出生”到應用

文章出處:濰坊向日葵app官网下载安卓防護用品有限公司 人氣:195發表時間:2020-10-14

1990年,美國消防協會(NFPA)和美國資料試驗協會(ASTM)提出和開展了附加的規範,並且被OSHA認可。NFPA1991規範的對氣密防護服提出了功能要求,這些要求包含防化學和防火焰測驗,可防21種根本化學品。

美國環境局(EPA)指定作業安全與清潔管理局(OSHA)有職責對在損害資料和汙染廢猜中的工人供給健康和安全維護,OSHA對一切環境的安全規程做出清晰的反映,這些安全規程對一切的OSHA方案都清晰了運行規範。

In 1990, the American Fire Protection Association (NFPA) and the American information and Testing Association (ASTM) proposed and carried out additional specifications, which were recognized by OSHA. The functional requirements of airtight protective clothing are put forward in NFPA 1991. These requirements include chemical and flame resistance tests, which can prevent 21 kinds of essential chemicals.

The United States Environmental Agency (EPA) has designated the work safety and cleaning Administration (OSHA) to provide health and safety maintenance for workers who are in danger of damage data and pollution. OSHA clearly reflects the safety regulations of all environments, and these safety regulations clearly define the operation specifications of all OSHA programs.

根本的OSHA規範要求四級維護:A,B,C,D四級,處於每種風險等級的工人都有必要裝備相應等級的防護設備和防護服,以充沛維護運用者。 

Level A--表明最大的風險程度,它對人的呼吸、眼睛或皮膚造成損傷, 這些損傷可能來自有毒蒸氣、氣體、微粒、化學飛濺、沉溺或觸摸有毒資料。 它要求全關閉化學防護服,這種防護服有必要帶SCBA或管路式呼吸器和恰當的附件。Level A化學防護服也可做成契合NFPA1991 規範。

Level B 表明環境要求最高的呼吸維護,但對皮膚維護的要求不高。

它要求SCBA或帶逃生氣瓶的正壓式管路呼吸器,再加有頭罩的話、學防護衣(連體式和長袖夾克;連體式,一或二件防飛濺防化服;或可獨自運用的連體防化衣)。 

The basic OSHA specification requires four levels of maintenance: Level A, B, C, D. workers at each risk level must be equipped with corresponding level of protective equipment and protective clothing to fully maintain users.

Level a - indicates the maximum level of risk, which may cause damage to the person's breath, eyes or skin, which may come from toxic vapor, gas, particles, chemical spatter, addiction or touching toxic information. It requires full closure of chemical protective clothing, which is necessary with SCBA or line respirator and appropriate accessories. Level a chemical protective clothing can also be made to comply with NFPA 1991.

Level B indicates that the environment requires the highest respiratory maintenance, but the requirement for skin maintenance is not high.

It requires SCBA or positive pressure pipeline respirator with escape gas bottle, and protective clothing (one-piece and long sleeve jacket; one-piece, one or two pieces of anti splash chemical protective clothing; or one-piece chemical protective clothing that can be used alone).

防護服

另供給契合化學防護服未來歐洲規範:

第一類:氣密型防護服 

第二類:非氣密型防護服 

第三類:液體細密型防護服  

第四類:噴霧細密型防護服  

第五類:粉塵細密型防護服

第六類:有限噴液細密型防護服

In addition, it can meet the future European specification of chemical protective clothing

Class I: air tight protective clothing

The second category: non airtight protective clothing

The third category: liquid fine type protective clothing

The fourth category: spray fine protective clothing.

Category 5: fine dust protective clothing

Class 6: limited spray fine protective clothing

1、防護麵料

正確挑選化學防護服,了解各種化學物質的穿透或浸透對被防護織物很重要。 

穿透試驗檢測氣體,液體和固體經過另外一種固體物質的小孔或開口。穿透試驗用於測驗織物會不會漏,能不能阻撓微粒或化學物。當一種化學物被吸收後,在織物的一側飽和,然後釋放出吸收物或擴散到織物的另一側,這就是浸透。發作浸透時織物的外表不一定要有小孔或開口,關於露出於有害液體,蒸汽和氣體的織物來說,浸透試驗很重要。

2、可見度 

關於處理突發事件的人來說,可見度高有利也有弊。舉例來說,在風險的環境中時,處理突發事件的人能被其他人看到很重要,而有害物的突發事件一般不會發作在適宜的環境中,需求化學防護服具有高可見度是一個重要的特征。另外,也有這樣的狀況,由於但是度高而被發現與觸摸化學物或生化物製劑相同風險。

3、縫線結構 

如果沒有強而緊的縫口,世界上最好的織物都是沒有用的,一個鬆的線頭,缺口, 就會移走你和環境之間的屏障,使你處於風險之中。

4、防護服品種

不同的作業喲啊不同品種或裝備的防護服,這就恰似向日葵app官网入口幸福宝供給很多品種防護服的原因,從頭套,背心到圍裙,連體服和全關閉防護服(B級和A級)。全關閉防護服有前進口和後進口兩種挑選,既有背部平整用於外接氣源的呼吸器,也有與SCBA配套的背部突起的防護服。

5、防護服結構 

全關閉防護服有許多部件和挑選。不同的狀況需求不同類型的麵罩。

1. Protective fabric

It is very important to select the chemical protective clothing correctly and understand the penetration or penetration of various chemicals.

The penetration test detects the passage of gases, liquids and solids through holes or openings in another solid substance. The penetration test is used to test whether the fabric can leak and block particles or chemicals. When a chemical is absorbed, it saturates on one side of the fabric, then releases the absorbent or diffuses to the other side of the fabric, which is called soaking. It is not necessary to have small holes or openings on the surface of the fabric when it is saturated. The penetration test is very important for fabrics exposed to harmful liquids, vapors and gases.

2. Visibility

For those who deal with emergencies, high visibility has its advantages and disadvantages. For example, in a risk environment, it is important that the person dealing with the emergency can be seen by others, while the emergency of hazardous substances will not occur in the appropriate environment. It is an important feature that the chemical protective clothing has high visibility. In addition, there are also situations where the risk of being found to be the same as touching chemical or biochemical preparations due to its high degree of exposure.

3. Stitch structure

Without strong and tight seams, the best fabrics in the world are useless. A loose thread, a gap, will remove the barrier between you and the environment, putting you at risk.

4. Types of protective clothing

Different types or equipment of protective clothing for different operations, which is just like the reason why we supply many kinds of protective clothing, from headgear, vest to apron, one-piece suit and fully closed protective clothing (Grade B and a). There are two kinds of full closed protective clothing: front inlet and rear inlet. There are not only respirators with flat back for external air source, but also protective clothing with protruding back matched with SCBA.

5. Structure of protective clothing

Fully closed protective clothing has many parts and options. Different conditions require different types of masks.
