Fire Risk in the USA

Fireproof boxes are to withstand high temperatures. They are designed to reduce the flow of heat, protecting your valuables and documents. Do you think, a house fire is hardly probable in your location. I wouldn’t be so sure.

According to the US Fire Administration, 3,146 – 3,650 people throughout the USA die in a fire every year. Fire causes are various and dramatic. They include:

  • short circuits;
  • misuse of grills;
  • smoking;
  • faulty cooking and heating equipment;
  • children playing with matches;
  • lightning strikes.

The NFPA Association analyses the cases, trying to prevent human deaths, injuries, as well as property loss. The best fireproof box is able only to keep your valuables and documents safe. They remain intact during about an hour until the box is taken out or the fire is extinguished.

Wildfires are a common problem too. Multiple Kansas, Oklahoma and Texas areas are prone to them. However, residents of Southern California suffer from wildfires the most. The damage wildlife, acres of land and adjacent housing. The reason is in dry winds and sunny, desert climate.

Flood Types

Top-quality safes are water-resistant. They protect your important digital media, disks and photos in case of a flood. They remain dry for 1-3 days when the box is submerged underwater.

Are floods so common in the USA nowadays? Unfortunately, people are used to underestimating flood risk. Selecting a fireproof box for legal-size documents, we may pay less attention to its water protection properties.

Meanwhile, according to statistics, all 50 states experienced them during the last 5 years. Hurricanes Katrina and Harvey were the most destructive. By nature, flooding events are classified as:

  • inland;
  • river;
  • flash;
  • coastal;
  • urban.

Ice and debris jams happen when snow is melting. Persistent rainfalls can cause floods even in inland areas. Additionally, failure of drainage system may happen, exposing your legal and personal documents to danger.

St. Louis Port is prone mainly to river floods. For example, a large storm event happened in 2011 on the Missouri River. It started in May due to heavy rainfalls and extensive snowpack on the Rocky Mountains.

Do Fireproof Boxes Really Work?

The cases when fire or flood takes everything are undesirable. Important paperwork, at least passports and birth certificates should remain intact. What happens to them when the fire burns up to about 900° F?

  1. CD and DVD disks do work.
  2. Photos are not destroyed.
  3. Laminated identification documents and cards are ok.
  4. Paper documents may be damaged.

Unfortunately, A4 letters are spoilt by fire. Paper ignites at the temperature of about 451° F. It burns fast, contracting in fire. Therefore, look for the highest fire and water protection rating. Additionally, I would recommend you to put the papers to a fireproof bag first, then to a safe box.

What is the Best Fireproof Safe for Home Use?

Anti-theft, water and fire protection feature ultimate safe’s functionality. Household application implies also compact design, ease of use and usability. For example, carry handle and internal light are beneficial features. Waterproof seal is another good option.

What are the safes and chests made of? Common ones include durable, metal sides. Fire-resistant boxes are typically made of heat-resistant, composite materials. Vermiculite and perlite are the best ones. They don’t conduct heat. Therefore, the box content remains cool.

Do you want to get a discount for your homeowners’ insurance? It’s highly probable if you have:

  • carbon monoxide or smoke detectors;
  • fire extinguishers;
  • home security systems;
  • storm shutters;
  • updated pipes and circuit breakers.

Availability of a fireproof box may also impress your insurance agent. It does reduce the risk of your property loss. Additionally, in the event of a disaster, your policies and identity documents remain intact.

Range of SentrySafes

How do you think, which company is the oldest and the most experienced? SentrySafe manufacturer was founded in 1930. The factory is located in Rochester, NY. Meanwhile, it’s just an affiliate of the worldwide recognized Master Lock Company. Its headquarter is in Oak Creek, WI.

  • document, business and portable safes;

Are safes good? I think they are preferable for home use due to multiple user-friendly features. The boxes are well-designed, compact, coming with handy locks. Water protection that lasts for 72 hours is pretty good. However, 2-year limited warranty is not the longest in the industry.

UL Rating of SentrySafes

Is it the best safe brand? I think so because it’s reliable, field-specific and customer-oriented. But for the safes, it includes also UL (Underwriters Laboratories) that test and approve products.

Quite naturally, the boxes differ by sizes, materials, lock types and applications. Fire and impact protection classes are very important characteristics.
