How to Choose a Safe in Singapore: A Safesmith's Guide

Most people choose a safe by price and size. A safesmith chooses one by what it has to stop. Uncle Thomas has opened safes of every type since he trained in the United States, so he's seen which ones hold up and which ones don't. Here's how to choose one that fits what you're protecting.

1. Start with what you're protecting

You're keeping	The main threat	Look for
Cash, gold, jewellery, watches	Burglary	A burglary-resistance rating, fixed down
Passports, deeds, certificates, wills	Fire	A fire rating for paper
Hard drives, USB sticks, backup disks	Fire (heat)	A fire rating for data or digital media
A mix	Both	A safe rated for burglary and fire

A fire safe isn't automatically hard to break into, and a strong burglary safe isn't automatically fireproof. Check for both ratings if you need both.

2. Understand burglary ratings

The most widely used burglary standards come from Europe:

• EN 14450 (grades S1 and S2) covers lower-security safes, typical for homes with modest valuables.
• EN 1143-1 (grades 0 to XIII) covers higher-security safes. Each step up resists attack for longer.

Insurers often link how much they'll cover to the safe's grade. Before you buy, ask your insurer what grade they expect for the value you plan to keep. Many cheap safes carry no independent rating at all. A genuine rating comes with a certification label from a testing body, usually inside the door.

3. Understand fire ratings

• For paper: look for a rating that keeps the inside below about 177°C (350°F) for a stated time, such as 30, 60 or 120 minutes. The common American rating is UL Class 350. European equivalents include EN 15659 and EN 1047-1.
• For data: electronics are damaged at much lower temperatures, so look for a data rating that keeps the inside below about 52°C (125°F), such as UL Class 125. A paper-rated safe can still cook a hard drive.
• Duration matters as much as temperature. A 60-minute rating means the inside stayed below the limit for an hour in testing.

4. Plan for Singapore's humidity

Many fire safes use insulation that holds moisture, which is part of how they protect against heat. In Singapore's humid climate that can mean damp documents, tarnished silver or rusting watch parts. Keep a desiccant (silica gel) pack inside, change it regularly, store important papers in sealed sleeves, and open the safe now and then to air it.

5. Choose the lock

Lock	Good for	Watch out for
Electronic keypad	Quick to open; code easy to change	Batteries. Change them yearly and know where the override key is.
Mechanical dial	No batteries; long-lasting	Slower to open; changing the combination needs care.
Key	Simple	Lost or copied keys. Keep track of every key.
Biometric (fingerprint)	Fast access	Make sure it has a backup code or key.
Dual control (code plus key, or two codes)	Businesses where no one should open the safe alone	Needs two people present.

6. Size, weight and bolting down

• Buy bigger than you think you need. Most people run out of space within a few years.
• Fix it down. European safe standards expect burglary-resistant safes under 1,000 kg to be anchored. A small safe that isn't fixed down can simply be carried away and opened somewhere else.
• Check delivery. Measure doors, lifts and stairs, and check the floor where the safe will stand. In a condo or rented home, ask management or your landlord before drilling into the floor.

7. Where to put it

Choose a spot that's out of sight, not the first wardrobe a burglar would check, and where the safe can be fixed to the floor or a solid wall. Keep it out of places prone to water, like next to a bathroom wall or under an air-conditioner.

8. For businesses

• Dual control so no single person can open the safe.
• A deposit or drop slot if staff need to bank cash without being able to open the safe.
• A clear process for who holds codes and keys, and for changing codes when staff leave.
• Insurance requirements. Pawnbrokers, for example, must keep pledges secure and insured against theft under their licence conditions.

9. Check your insurance

Home contents policies often have limits for jewellery and valuables, and some cover items differently when they're kept in a home safe or a bank vault. Read your policy's valuables section, or ask your insurer, before deciding how much to keep at home.
