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.

PPE Use in Healthcare Settings I: Donning

PPE Use in Healthcare Settings I: Donning

Donning PPE must be completed before contact with the patient. This process protects from infectious agents. The sequence and action included in each donning are critical, and the steps must be systematic to avoid exposure to pathogens. The institutional policy also needs to be followed while donning PPE. The pre-donning preparations are gathering equipment, inspecting the PPE equipment for tears, holes, or damage, removing jewelry, removing any garments below the elbows, and tying the hair...

Accessory Structures of the Eye

Accessory Structures of the Eye

Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based Precautions II: Airborne and Protective Environment

Transmission-based precautions are for patients infected or suspected to be infected (or colonized) with organisms posing a significant risk to others. The transmission precautions include airborne and protective environment precautions.
Airborne precautions:
Use airborne precautions when treating patients known or suspected to have diseases that spread through the air—for example, tuberculosis or measles. These organisms are present in smaller droplets expelled by an infected person and...

Glaucoma: Overview

Glaucoma: Overview

Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

Summary

Selecting prescription eye protection requires prioritizing impact resistance over optical and cosmetic factors. This review examines lens materials, testing standards, and selection guidance for optimal safety.

Area of Science:

Ophthalmology
Materials Science
Occupational Safety

Background:

Non-prescription eye protection materials, like polycarbonate, have long prioritized impact resistance.
Prescription eyewear selection often balances optical clarity and aesthetics over safety.
Australian/New Zealand standards mandate impact resistance as the primary requirement for prescription eye protection.

Purpose of the Study:

To review evidence on the impact resistance of available ophthalmic lens materials.
To detail the standards used for testing impact resistance in eye protection.
To provide guidance for selecting prescription eye protection materials based on impact resistance.

Main Methods:

Literature review of impact resistance studies for lens materials.

Analysis of Australian/New Zealand standards for prescription eye protection testing.

Synthesis of data to guide material selection for safety.

Main Results:

Polycarbonate is the current standard for non-prescription eye protectors due to its impact resistance.
Prescription lens selection involves numerous materials and coatings, often prioritizing optics and cosmetics.
Impact resistance is paramount for prescription eye protection, superseding other considerations.

Conclusions:

Impact resistance must be the foremost requirement in selecting prescription eye protection materials.
Understanding material properties and testing standards is crucial for ensuring adequate eye safety.
This review offers guidance for informed selection of safer prescription eyewear.
