Master Lock Fire Safes for Documents and Valuables

Master Lock Fire and Water-Resistant Safes

What Is a Fire Safe?

A fire safe is designed to protect specified contents from heat and fire for a defined period under tested conditions. The Master Lock range on this page includes digital fire safes with either 60-minute or 120-minute fire-protection durations.

These safes are designed primarily for important documents and valuables in homes, offices and commercial premises. Selected models also provide tested resistance to water exposure, offering additional protection against risks associated with flooding, sprinkler systems or firefighting.

60-Minute and 120-Minute Fire Protection

The Master Lock LFW models listed on this page provide one-hour fire protection, while the LTW models provide two-hour protection. The appropriate duration depends on the intended contents and the fire classification required.

A longer fire-protection time does not automatically make a safe suitable for every type of item. Paper documents, digital media and electronic storage devices can require different internal-temperature limits, so always check the individual model specification.

Fire and Water Protection

Fire and water protection address different risks. Applicable Master Lock models are tested for resistance to water exposure as well as fire, but this should not be interpreted as permanent waterproofing or suitability for continuous submersion.

Check the specification for the selected safe to confirm its tested fire duration, water-resistance conditions and suitable contents.

Digital Fire Safes

The Master Lock fire safes listed here use digital locking for coded access. Features such as override arrangements, alarm functions, battery requirements and code management vary between models.

The LFW205TWC also provides an alarm function. Refer to its technical specification for details of the alarm operation and triggering conditions.

Fire Safes for Documents and Valuables

Typical applications include the storage of passports, certificates, property records, insurance documents, confidential paperwork, cash, jewellery and other personal or business valuables.

Do not assume that a safe intended for paper documents will provide adequate protection for USB drives, hard drives or other electronic media. The fire classification must be suitable for the material being stored.

Choosing the Correct Fire Safe

When comparing Master Lock fire safes, consider the required fire duration, intended contents, internal capacity, water protection, lock functions and the available installation space.

For larger models, also check the safe's weight and delivery route, including doorways, corridors, stairs, lifts and the supporting surface at the final location.

Fire Protection and Security Ratings

A fire rating and a burglary or cash rating are not the same thing. A safe offering one or two hours of fire protection does not automatically have a certified cash rating, valuables rating or burglary-resistance grade.

If a safe is required for insurance, regulatory or organisational purposes, confirm the required fire classification and security grade before ordering.
