Are Heated Vests Safe?

Sub-zero temperatures are hard to tackle, and majority people opt for heated clothing except layering up. The heated vests are a popular commodity in this case. Their sales have seen a record-high with the emerging technology related to heated apparel.

Safety is the top feature of this vest when used properly. Battery-powered versions of these vests are ideal with regard to cold weather activities.

Their vest have gained worldwide acclaim due to their high effectiveness against harsh weather conditions. They specialize in insulating the person wearing them effectively. This article is created around the safety concerns of heated vests, with elaboration of major and minor issues.

Technical Analysis of Heated Vests

To facilitate functioning and heat generation, electrical current is utilized in heated vests. These flow through small wires. Made up of materials such as carbon-fiber or metal alloys. Such alloys include Nickel-chromium. Withstanding thermal cycling is their main feature. With the vests the wires are covered with a thin layer of fabric, to keep them to moving around and being away from the wear to avoid shocks.

On the inner side of the fabric, usually in the pocket of the vest is a rechargeable battery carefully placed. On the upper part of the chest, a vest regulator is sewn. The individual who wears it can adjust the heat output by changing settings through this regulator. The electrical wires mentioned earlier generally distribute electricity causing the vest to warm up thoroughly.

Working of Heated Vests

This apparently contain in-built heating elements. A portable battery connects these heating elements together. They are also strategically placed at the abdomen, back and target areas to create a well-rounded effect throughout the vest. After the vest is activated, these heated elements circulate electricity and simultaneously warmth evenly within the vest. It helps keep the individual warm in freezing conditions.

Battery Operated vs USB-Powered

Battery-Operated Vests

A rechargeable battery pack in the main element of these vests. These actively power the heating elements continuously.

  • A long run time is a big advantage of a battery-operated heated vest. These can work anywhere between 5–8 hours.
  • Without any power source in reach, these vests can function independently taking power from the battery attached to it.
  • There is also another factor to consider that the heated vest battery-powered vest are heavier to carry as they also contain the weight of the batteries within.
  • Due to added batteries, thee are considered more expensive.

USB-Powered Vests

Connection to a power source either If it is a computer or a portable charger is used to activate the heating elements in USB-powered vests.

  • A USB cord is used to connect the main circuit with the power source in this USB-powered vest.
  • These are compact and portable in nature. Transportation and carrying these vests is easier as compared to Battery-Operated Vests.
  • They have a limited battery capacity. They constantly have to be connected with a power source to operate properly. Heated blankets come under the same category.
  • They are cheaper in price due to having no battery attachments included.

Materials Relevant to Construction of Heated Vests

Different manufacturers use different materials to make a heated vest, but the most common ones used are as follows.

1. Outer Layer

Polyester or Nylon material is used in the composition of the outermost layer of a heated vest. Their weather resistant qualities help them maintain their spot. It also offers a protective covering to the interior components of the vest from wear and tear caused by external extreme conditions.

2. Insulating Part

Heat can be dissipated If not held in by an insulating layer. It helps individuals retain their body heat as well as the heat generated by the heating elements themselves. Fleece, synthetic fibers and features are the three popular and durable insulating materials used.

3. Heating Elements

The most important part of a vest are its heating components, and it is vital that these are made of highly-conductive materials. Heat generation should also be a quality f these. Common materials used are carbon fiber in most heated vests. Metal compounds such as Nickel-chromium are also employed in some.

4. Battery Pack

High power density is required the battery pack that may be used in a heated vest. Batteries such as Lithium-ion batteries re idea in this regard. They are compact to carry. They are also safe and long-lasting making them highly appropriate t used in heated apparel.

Possible Hazard and Challenges of Heated Vests

1. Potential Overheating and Burns

These heated vests can overheat which is a big concern for all the users. Prolonging use of the vest for more than 8 hours is recommended to not do to avoid any accidents. Apart from this, its heat settings can be adjusted to match the requirements of the user.

In terms of feeling excessive warm, it is advised to take off the vest to cool down. If obtained from a poor manufacturer then poor insulation covering the heating elements can cause overheating incidents. Burns in the form of painful blisters can be caused as a result. If the battery pack is leaking from anywhere, avoid using it to prevent sustaining injuries.

2. EMFs and Health Relevance

Low-intensity EMFs are generated by heated vests which is a known fact. These come under the non-ionizing spectrum. This makes it a relatively safer approach than X-rays or Gamma rays, which can potentially more harmful. Due to having such low intensity the EMFs created by these vest have no atom ionizing abilities, thus these can cause no to minimal harm.

Electromagnetic Hypersensitivity(EHS) is a prevailing concern among most individuals. Headaches, nausea etc are a result on this concern. EMF shielding is used in many vests to eradicate this. High safety is a priority of SGKOW’s heated vest, and they come along with such features to ensure optimum performance.

3. Battery Malfunctions

Overheating and battery malfunction in generally the cause of prolonged used which can cause excessive heat generation. If the battery is not cooled properly then it can easily cause the battery to malfunction. Explosion or fire incidents causing severe burns can be a result of this. The battery can also be effected If it suffers physical impact such as sustaining falls etc.

Most old batteries degrade which can cause battery failure. There is another concern where If the battery leak while the individual is wearing the vest it can cause serious burns from the inner material of the battery.

Regular monitoring of the battery can prevent this from happening. Leaks, cracks and dents can be observed in the battery earlier on that show degradation. Overcharging a battery should be immediately stopped to control its degradation process.

Distinct Safety Measures in Ultra-modern Heated Vests
