概括

一次性酸手套的透性测试需要改进. 标准化测试可能会低估化学物质的透,特别是压力较低的薄手套,可能会危及工人.

科学领域:

职业健康和安全问题职业健康和安全问题
材料科学材料科学材料科学
化学工程是化学工程的重要组成部分.

背景情况:

目前手套的化学耐药性测试使用室温的平面样本,而不是模拟现实条件.
这种标准方法 (ASTM F739) 可能不能准确地反映在动态条件和高温下整个手套的性能.
工人保护依赖于对一次性酸盐手套透率的准确评估.

研究的目的:

在模拟使用条件下,评估通过整个一次性酸盐手套的化学透率.
为了比较来自机器人手模型 (紧握与非紧握) 的透数据与标准ASTM F739方法.
为了研究手套特性 (厚度,多孔性,烯酸含量) 对透的影响.

主要方法:

测试了四种类型的一次性酸盐手套的厚度,多孔性和酸含量.
在35°C时使用右手机器人手 (紧握和不紧握) 和ASTM F739技术测量了烯透度.
气色谱-质谱法 (GC-MS) 用于分析透样本.

主要成果:

透率 (标准化突破时间和稳定状态透率) 受烯酸含量,厚度和多孔性的影响.
只有最薄的手套,与手握和ASTM方法相比,与非握手相比,透率明显更高.
对于更厚的手套,ASTM测试数据与机器人手测试没有显著差异,但与制造商数据有所不同.

结论:

标准的手套透测试可能会高估保护,因为紧力会增加化学物质的透.
使用超薄一次性亚酸盐手套的工人面临更高的化学透风险.
需要对各种化学物质和力量进行进一步的研究;双手套可能是暂时的解决方案.

Hand hygiene

Hand hygiene

Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

Personal Protective Equipment

Personal Protective Equipment

Personal protective equipment (PPE) is unique clothing or equipment worn by an employee to minimize or prevent exposure to infectious agents. PPE creates a barrier between the employee and the infectious materials. PPE must be readily available in the patient care area. PPE includes gloves, gowns and aprons, masks and respirators, goggles, face shields, shoes, and headcovers:

PPE Use in Healthcare Settings II: Doffing

PPE Use in Healthcare Settings II: Doffing

The sequence of removing or doffing PPE starts with the gloves, as they are the most contaminated. Next is removal of the face shield or goggles, as they would interfere with removing other PPE. Then remove the gown, followed by the mask or respirator. Perform hand hygiene between steps if hands become contaminated and immediately after removing all PPE. Generally, the outside front and sleeves of the isolation gown, the goggles or the mask, the respirator, and the face shield are contaminated.

Abrasion Resistance of Concrete

Abrasion Resistance of Concrete

Abrasion resistance is an essential characteristic of concrete that determines its durability and longevity under various wear conditions. Concrete surfaces are vulnerable to different types of abrasion. For instance, surfaces may wear down due to the constant movement of vehicles or be eroded by solids carried in water, as seen in concrete canal linings. Specific tests are conducted to measure the abrasion resistance of concrete.
One such test is the revolving disc test, where three plates...
