What are face masks?
“Source control” refers to preventing the wearer’s respiratory droplets from traveling into the air and onto other people when the person wearing the mask coughs, sneezes, talks, etc.
These are not suitable for use during medical and surgical procedures in healthcare facilities, where exposure and risk of transmission of infection are higher. These masks may be used by the general public and in community settings. Please refer to MOH’s guidance and FAQs on the use of masks.
Face masks are not regulated as medical devices under the Health Sciences Authority (HSA). Therefore, the quality and effectiveness of face masks are not regulated by HSA.
Are face masks useful?
These masks are particularly useful in public settings (e.g. when using public transport) when strict adherence to safe distancing may be challenging.
As the contagious Delta variant of COVID-19 continues to spread in the U.S., you need to mask up—even if you're vaccinated. Here's how to find the right face mask for you.
Myth #1: More Texture Means Better Grip
One of the most common misconceptions about
Surface treatment is the most significant factor in the grip level of a glove. Natural latex is inherently sticky, or tacky, much like glue. Without proper processing, natural latex sticks together like a large ball of adhesive. To reduce this tack, the surface must be treated. The most common surface treatments are surface chlorination and coating. Chlorination changes the surface properties and creates a hard, lower-tack shell around the glove. Coating technology adds a new, lower-tack layer to the glove.
Reality: Surface tack, or grip, can be controlled by the level of chlorination or the characteristics of the coating.
Myth #4: Fillers Always Diminish Glove Performance
Fillers are used broadly in gloves. Most manufacturers use or have the ability to use fillers to help reduce the cost of making a glove. Fillers are often difficult, but possible, to detect through advanced technologies such as Thermal Gravimetric Analysis.
Fillers help to reduce the cost of a glove and, up to certain amounts, actually can improve specific performance characteristics. For example, tear strength is significantly improved in natural
Myth #5: All Allergy Issues Can Be Addressed by Using Nitrile or Vinyl Instead of Natural Latex
Glove-related allergies are a primary concern to many glove users. The belief that glove-related allergies are caused only by natural latex is a common one. Latex allergies are the most serious glove allergies because they can be systemic and cause anaphylactic shock. Latex allergies are also the most common type of glove allergies.
Some users confuse chemical allergies with latex allergies. There are often components in both nitrile and vinyl gloves that can elicit a chemical allergy. For example, nitrile gloves, like natural latex gloves, often use carbamates or thiazoles, which can cause a skin allergy. Certain vinyl gloves use activation agents that can also cause skin allergies. In all cases, the less a glove is washed, the more chemical residue is available for potential contact to the user. Users should consult their physician if they suspect an allergy to gloves.
Reality: Natural latex is not the only glove material that can cause allergies.
Even within the same material, there are significant differences from manufacturer to manufacturer. Other factors influencing glove performance are raw materials, formulation, process, and washing. These vary significantly from glove to glove and can result in performance differences in most applications. Typically, standards for the different materials also are not harmonized. ASTM exam glove standards have different tensile strength requirements for latex, nitrile, and vinyl. Vinyl has the most relaxed strength requirement, followed by nitrile, while latex has the highest tensile strength requirement of the three, and
Myth #9: Lower Priced Gloves Always Result in Cost Savings
One of the biggest mistakes made by disposable glove buyers is buying based solely on price. The overall value of a glove is much more complicated than just the price of a box. In addition to price, buyers should consider durability in the application, safety risks, and productivity.
Should protective suits be used when managing COVID-19 patients?
In its recommendations for the rational use of PPE, the WHO stated that coveralls (sometimes called Ebola PPE) are not required when managing COVID-19 patients. Headcovers (hoods) that cover the head and neck, used in the ontext of filovirus disease outbreaks, are not required either.

with good filtering efficiency help prevent people who have COVID-19 from spreading the virus to others by acting as a “source control”. Wearing a mask in public places limits exposure to respiratory droplets and large particles and reduces the risk of community spread of infection. This is especially relevant for asymptomatic or pre-symptomatic infected wearers who feel well and may be unaware that they are infectious.These masks are particularly useful in public settings (e.g. when using public transport) when strict adherence to safe distancing may be challenging.

is that more texture results in better grip. In fact, texture has very little effect on grip. It is possible to make an extremely textured glove with a low grip and a smooth-surfaced glove with a high grip.Surface treatment is the most significant factor in the grip level of a glove.

when a moderate amount of calcium carbonate is added. The keyword is "moderate." Fillers up to about 15 percent are tolerable; anything above that can become detrimental to the performance and quality of the glove in use. Some manufacturers have experimented with up to 50 percent filler, with limited success.Myth #5: All Allergy Issues Can Be Addressed by Using Nitrile or Vinyl Instead of Natural Latex
