Safety Glasses VS Safety Goggles

Comparing Eye Protection

Workplace accidents causing eye injuries are common. Therefore, it is important to invest in eye protection safety when working in hazardous environments. In general, damage and injuries occur due to the open exposure of the eyes to adverse conditions.

As long as the eyes are sufficiently covered using safety glasses or goggles, the eyes will be shielded from danger.

If you are uncertain about the right protection for your workplace, you should consider this short discussion on eye safety.

Understand the Potential Hazards

eye protection

When choosing your protective eye gear, it is important to understand your work environment and the potential hazards.

The dangers will depend on the type of operations that are carried out in your residential, commercial or industrial premises.

The most common forms of hazards are solid objects and particles. Solid projectiles can cause irreversible harm to the eye tissues, and the damage could escalate into infections and even vision loss.

The common projectiles that could be dangerous include concrete, metal, wood and tools. You should also note that particles of dust or similar contaminants will injure the eyes by abrading the cornea.

Chemicals will have a dangerous effect on your eyes, and continuous exposure will lead to long-term degradation of the tissues. You will need to guard against splashes of liquid compounds and fumes from vaporized chemicals.

Radiation is a hazard which is often ignored in the workplace because its immediate impact is not as prominent as chemicals or solid projectiles. Unfortunately, radiation in the form infrared radiation, ultraviolet light and visible light will increase the risk of vision loss over time.

If you work in a laboratory or hospital, you will need to guard against infections pathogens. Disease-causing microorganisms can infiltrate eyes through blood and other body fluids.

Prevent Eye Damage

Your eye protection safety plan for your workplace should begin by evaluating the worksite and understanding the specific hazards. Then, you should eliminate dangers which can be avoided before starting work.

For instance, you can limit the risks posed by projectiles in industrial spaces by using screen protection, machine guarding and engineering controls.

Finally, you must choose the right eye gear for personal protection.

Choosing Your Protection

There are two primary types of protective eyewear for workplace applications: safety glasses and safety goggles.

Both of these are beneficial for shielding, but they are not both suitable for all applications. It is important to make a comparison before choosing the best item for your needs.

Safety Glasses

For most workplaces, safety glasses will suffice for worker eye protection. In general, this type of gear is designed to provide impact protection from solid projectiles.

If you need to keep your eyes safe from flying objects and debris when working, you should opt for eye glasses.

Typically, the lenses and the frames are tested to withstand tough objects like steel balls. Therefore, you do not need to be concerned about eye injuries.

It is also important to note that safety glasses are comfortable for long-term wear.

Safety Goggles

Safety goggles provide superior, all-round protection against workplace hazards. In addition to solid projectiles, this type of eyewear will keep the eyes safe from small particles, liquids and fumes.

Unlike safety glasses, goggles do not have gaps around the bottom, top and sides. Instead, the eyewear will form a tight seal around eye area of the face.

Safety goggles are ideal if you are concerned about chemical exposure, infectious pathogens, metal filings and dust.

There are different types of safety goggles on the market: direct vent, indirect vent and unvented goggles.

You must choose the right protective product to guarantee optimal protection in your workplace.

Direct Vent Goggles:

Direct Vent Safety Goggles
Direct Vent Safety Goggles

The protective eyewear is designed with multiple perforations to allow for ventilation. The holes prevent fogging of the goggles.

Unfortunately, the design limits the protection provided against small particles, liquids and vapor.

Indirect Vent Goggles:

Indirect Vent Safety Goggles
Indirect Vent Safety Goggles

Like the direct vent eyewear, these have perforations. However, the venting holes are covered, limiting the flow of liquids and particles.

The ventilation will provide vapor protection, but the effectiveness will be limited.

However, the eyewear will be susceptible to fogging. Choose anti-fog lens to minimize the rate of clouding.

Forensic Swabs For Crime Scene DNA Evidence

Advancing Swab Science

Puritan Sterile DNA Controlled Cotton Swab with Transport Tube P25-806-1PC-BT-FABUSA used as a forensic swab and diagnostics.

For many years, fingerprints evidence was the standard for investigating and linking suspects to a crime scene. Rapid evaluation of forensic swabs science has shaped DNA evidence as the gold standard.

A few cells are all an investigation team needs to obtain in order to get enough DNA information to identify a suspect.

DNA analysis has been helping law enforcement agencies solve crimes for more than three decades.

DNA swabbing plays a critical role in streamlining crime scene investigation. They enable forensic professionals to extract valuable information from even the smallest samples of saliva, urine, blood, and other tissues.

However, it is important to consider that the effectiveness of forensic analysis depends on the quality of sample collection tools and methods. Low-quality sample collection, storage and transportation media can lead to potentially invalidated results.

How to swab for DNA evidence

The collection of DNA evidence is a highly effective technique used worldwide to solve investigations.

It is essential for medical examiners, forensic scientists, and crime scene investigators to master DNA specimen collection methods.

At a crime scene, both physical evidence, such as a weapon, and biological evidence such as sweat or blood could yield DNA samples. If someone touched a weapon or object, various forms of touch DNA might have been left behind.

In case the crime scene provides a clear source of DNA, the sample can be collected using proven tools like swabs. Here is a simple process to swab for DNA evidence:

Preparation

Preparation is the first step you should take to ensure effective DNA swabbing. Make sure your staff is well-trained and well-equipped. Approved personal protective equipment (PPE) such as gloves (and possibly even shoe covers, hair nets, and masks depending on the scene) must be used during DNA swab collection.

Proper preparation will help you avoid contamination of samples which can become a critical issue in court proceedings.

Sterile swabs, distilled water, transport media, evidence tape and flashlights are some of the essentials your evidence collection kits should contain.

Swabbing

Swabbing is a preferred DNA sample collection method over taping. There are swabbing techniques used in accordance with the sample type (touch DNA, blood, sweat).

No matter the swabbing methods you implement, change gloves and forceps after each item is necessary to prevent cross contamination. Following are the three most popular techniques:

  • Swabbing for touch DNA
  • Double Swabbing for touch DNA
  • Swabbing bodily fluids like blood

Preserving Forensic Swabs

One of the most important parts of collecting cells is ensuring that the swab is completely dry during preservation and transportation. Some of the modern collection tubes are designed to ensure both effectiveness and convenience in preserving samples.

Here are some tips that will help you conduct a reliable DNA evidence collection process:

  • Wear protective gloves before removing the swab from its wrapper
  • Touch only the handle of a forensic swab
  • Pre-moisten the swab with sterile distilled water if the sample is dry
  • Place the tip of the swab on the surface and rotate it gently to allow tissues to absorb into the fibers
  • Put the swab tip-first into appropriate packaging and allow the sample to dry

There are several environmental factors such as temperature, mold, and bacteria that can affect the DNA at the crime scene.

Follow the pre-defined DNA collection procedures even if the crime scene has been compromised.

Use DNA-Controlled Swabs

When the job is to swab for evidence at crime scenes, you can choose from a number of techniques. But when it comes to DNA evidence collection, it is recommended to use DNA-controlled or DNA-free buccal swabs.

If the swab is not free of human contaminants like DNase and DNA, it could compromise the sample, and consequently, the case.

Therefore, always use buccal or DNA swabs certified by an independent laboratory.

Following are two popular types of buccal swabs used widely at crime scenes:

Flocked Swabs

HydraFlock® Flocked Sterile Swab, Elongated Tip P25-3806-H-2
HydraFlock® Flocked Sterile Forensic Swab, Elongated Tip P25-3806-H-2

DNA-free flocked swabs are ideal when you have to deal with an extremely small sample size.

Flocked swabs are being increasingly used for forensic processes due to their unique structure which helps crime investigators collect, retain, and elute specimen better than other low-quality swabs.

A flocked swab is also handy when it comes to collecting touch DNA from fingerprints or skin cells, or residue from arso, gunshots, or explosions.

Cotton Swabs

Puritan Cap-Shure Sterile Cotton Forensic Swab: 25-806-1WC-EC

If the sample is large enough and there is no need for advanced collection and elution, a sterile cotton swab, either with polystyrene or wooden handle, will do the job.

If it is not required to transfer the sample to FTA cards, it is recommended to use cotton swabs, not only for DNA collection but also for other medical applications.

When Should Hard Hats Be Replaced?

Hard Hats End Dates

Work environments where the potential risk of head injury is higher require hard hats. So that workers can protect themselves against falling or moving objects.

From construction to electrical repair, workers need the protection that only functioning safety hard hats can provide. Since a hard hat is a personal protective equipment (PPE) worn daily, you may be wondering when you should replace your old hard hat.

Hard hats are made of high-density polyethylene which is wear-resistant and durable material. Still, it is a material that breaks down.

Exposure to harsh work environments [such as chemicals and temperature extremes] and daily wear and tear, degrade the protective properties of hard hats.

It is a common practice of workers from some states to replace their safety hats after 6 months of use due to harsh weather conditions.

Inspect your hard hat daily

A hard hat can be the only protective item standing between a worker and serious injury. But these safety equipment items are not indestructible. They wear over time and succumb to damage from an impact or weather.

So, inspect your safety hard hats daily and look for the following signs:

  • Cracks, dents, tears or holes in the shell
  • Cracks in the suspension system
  • Frayed suspension straps
  • Brittleness of the shell

Whenever you see these signs, replace your hat or the affected part immediately. Hard hats are used by a broad range of industries.

There is no standard criteria on when hard hats should be replaced. The wearer must check the hat and determine, based on its condition, whether it can provide a enough level of safety any longer.

Safety hard hats wear quickly in environments where employees are exposed to intense conditions. Such as sunlight and water pressure, or construction sites where there are falling objects, dust, and grime. The heat dries out the hat causing it to crack.

These hats should be replaced more often than ones worn by workers who perform their duties indoor in clean conditions. In some cases, safety hats are rated based on their ability to withstand volts of electrical charge. When damaged or cracked, hard hats can’t withstand as much charge.

How to determine hard hats end date

ANSI ( American National Standards Institute ) and OSHA ( Occupational Safety and Health Administration) suggest to check the manufacturer’s instructions to determine the service life of your safety hats.

It is usually recommended that you replace hard hats  after 4 to 5 years of use, regardless of their appearance.

ANSI requires manufacturers print information such as the manufacture date inside the hard hat. The longest a hard hat should be in service is 4 to 5 years from the date of manufacture. But, it is only applicable when your hat is not damaged.

Moreover, if you work long hours in the sun or hostile environment, you may need to replace the hat after 2 years of use, or before.

Why it is necessary to replace old or damaged hats

As a worker, the expiration date on your hard hat serves as a safeguard. It is recommended to replace your hard hat before it reaches its expiration date. Some manufacturers recommend that suspension inside the hat must be replaced every 12 months.

Whether you use cap style hard hats or full brim hard hats, replace them when they become soft and weak without waiting for the expiration date.

Conclusion

The service life of personal protective equipment like hard hats is specific to the environment, job, and maintenance task. It is advisable that you replace hard hat suspension every two years.

Keep a record of buying date so that you can replace your head protection on time. Visually inspect the suspension, shell, and headband of the hard hat.

Don’t ignore dents, cracks or wear as it can seriously reduce the ability of a hat to provide sufficient protection.

Keep your personal protective equipment in top condition.

A Guide to Safety and Protective Apparel

Safety and Protective Apparel: Types And Applications

Protective and Safety apparel can seem like simple protective equipment. But selecting appropriate apparel can be a daunting process.

Many occupational applications including:

  • traffic management
  • construction
  • manufacturing,
  • chemical handling
  • networking
  • virtually all industries need safety gear of some variety

Some industries require employers carry out risk assessment and provide safety equipment. It’s important to understand what workplace hazards are and how we can address them.

Occupational Hazards and Assessment

As an employer, it’s your responsibility to protect your employees from occupational risks. For that, you need to put in place a risk management.

Relying solely on protective apparel to keep safe is only acceptable when you have carried out hazard assessment and control.

Selecting the right protective equipment for the nature of your employee’s specific job can be a challenging task. Consider applicable laws and draft safety policies and procedures.

It is also important to understand limitations of your protective equipment. If we take an example of a pair of protective eyewear, you will find a warning label saying, “not a substitute for good safety practices and engineering controls”. It means that PPE is the last line of defense against occupational hazards, not the primary one.

Types of Protective and Safety Apparel

There are so many different types of safety apparel that you can choose from depending on the environment of your facility or workplace.

We can classify safety apparel into the following two categories:

  1. PPE or protective apparel
  2. Safety Apparel

High Visibility safety apparel is a kind of workwear that improves your visibility at night or in bad weather.

It serves two purposes:

  1. Makes wearer more visible to traffic
  2. Makes them stand out against background environment

ANSI compliant workwear includes:

  • Durable Safety Jackets
  • Rain Pants
  • Thermal Pants
  • Reflective Safety Bomber Jackets

PPE or protective apparel protects the wearer against many workplace hazards. Such as dirt, chemical spills, containing hair and particle generation, etc.

Safety Apparel clothing is the basic need of workers who have to deal with various hazards on daily basis. However, these safety items allow for particle penetration.

PPE apparel handling can increase the likelihood of contamination. People who have to work in strictly controlled environments can’t wear regular PPE apparel as it can contaminate the environment. Use Disposable apparel designed for cleanrooms instead.

Safety Apparel/Gear

Following are some of the major types of safety apparel:

High-visibility safety clothing [safety apparel]:

High Visibility Safety Apparel
High Visibility Safety Outerwear Apparel

Defined as PPE apparel designed to make the wearer more visible. Low visibility is one of the causes of fatal occupational injuries at construction sites.

Wear high-viz shirts, pants, coveralls, jackets, or any other high-visibility safety apparel to ensure workers’ safety in low-light working conditions.

Whether in office or industrial setting, proper lighting makes all work tasks safer because the sense of sight generates about 85 percent of the information.

If your workplace does not offer proper lightning, make sure your staff wears the right high visibility apparel for the job.

Flame-Retardant Safety Gear Apparel

These safety apparel protect the wearer against heat and fire up to a certain level. You shouldn’t completely rely on fire retardant clothing when working with open flames.

Compare your work environment or the potential temperature extremes with the ability of your safety gear to withstand heat.

In addition to rubber gloves and aprons, PPE clothing is also designed to prevent harmful exposure to industrial chemicals.

Personal Protective Apparel

Disposable Apparel Protects yourself from particles, liquids, and chemicals in your work environment. Different materials to suit your specific application and offer different areas of protection.

CE apparel protects the wearer as well as the critical product or production process from contamination. The flat-folded CE safety wearables assure that particles do not escape into the critical environment. In cleanrooms, all sources of contamination are strictly controlled.

Disposable Food Safety Bouffant Caps
Disposable Food Safety Bouffant Caps

Clean rooms protective equipment is specifically designed to prevent airborne particles from entering the sterile atmosphere.

Industries such as pharmaceutical, medical, food, and space aeronautical maintain clean rooms as a part of their production processes.

Protective apparel plays a critical role in maintaining the sensitivity of a manufacturing environment.

Here is a couple of examples of protective or CE apparel:

Face Masks [protective apparel]:

Anti-Viral Face Masks
Disposable Anti-Viral Face Masks

Diverse protective product used by a large number of industries; notably, food and pharmaceutical. Face masks not only help the wearer inhale clean air but also function as a tool to maintain a healthy environment.
