The Sentry Safe Fire-safe waterproof document chest provides essential protection for your most important documents and digital media. This robust metal chest safeguards contents against fire damage for up to 30 minutes at temperatures reaching 843°C.
What makes this chest special? The waterproof seal prevents water damage whilst the captured insulation technology maintains safe internal temperatures during fire exposure. The tubular key lock system prevents unauthorised access.
Perfect for storing certificates, passports, photographs, CDs, DVDs, memory sticks and external hard drives. The convenient carrying handle allows easy transportation, whilst the compact 32.5cm internal width accommodates A4 documents. Weighing 12.4kg, this chest offers serious protection in a portable format.
The chest provides fire protection for 30 minutes at temperatures up to 843°C (1550°F). This duration is based on UL testing standards and represents typical house fire conditions. The captured insulation technology maintains safe internal temperatures below 177°C to prevent document charring and digital media damage. Most residential fires are controlled within this timeframe, making 30 minutes adequate protection for home use.
A4 documents fit but it's a snug fit due to the internal width of 32.5cm. Standard A4 paper measures 29.7cm wide, leaving minimal clearance. You can store A4 documents flat, but folders or ring binders may not fit. The 11.2cm height accommodates a reasonable stack of papers, certificates and photographs. Consider document organisation before purchase if you have bulky files.
The chest protects CDs, DVDs, USB drives, memory cards, external hard drives, tablets, smartphones and other electronic storage devices. The controlled internal temperature prevents heat damage to sensitive electronic components. However, ensure devices are powered off and properly stored in protective cases where possible. The chest is not designed for active electronics or devices requiring ventilation.
Yes, the waterproof seal creates a watertight barrier against water ingress from flooding, sprinkler systems, or firefighting water. The seal is designed to maintain integrity even when the chest is partially submerged. However, it's not intended for complete underwater submersion for extended periods. The seal works in conjunction with fire protection to provide dual security against the most common document threats.
The chest weighs 12.4kg, which provides security but affects portability. The integrated carrying handle makes transportation manageable for most adults, though you'll need both hands. The weight comes from the fire-resistant materials and thick walls necessary for protection. Once positioned, most people leave it in place rather than moving it frequently. Consider the final location carefully before loading with documents.
The chest includes the main safe box and two tubular keys. No batteries are required as this is a mechanical lock system. The keys are essential for access, so store the spare key in a separate secure location. No mounting hardware is included as this is designed for tabletop or freestanding placement. The chest arrives ready to use immediately.
No, the tubular key lock system prevents children from accessing the contents. The lock requires the specific tubular key to open and cannot be operated by small hands. The 12.4kg weight also makes it difficult for children to move or tamper with. However, ensure keys are stored safely away from children. This provides excellent security for sensitive documents in family homes.
Position the chest on a stable, level surface away from direct heat sources like radiators or sunny windows. A bedroom wardrobe shelf, home office desk, or secure cupboard works well. Avoid basements prone to flooding or attics with extreme temperatures. The chest should be easily accessible for regular use but not prominently displayed. Consider the 12.4kg weight when choosing elevated positions - ensure shelving can support it safely.
