Berdasarkan pemeriksaan keselamatan, pintu keluar kecemasan itu selamat.

Berdasarkan means based on or according to. It introduces the basis for the statement that follows.

So:

• Berdasarkan pemeriksaan keselamatan = Based on the safety inspection

It is common in formal or semi-formal Malay, especially in reports, notices, and official statements.

Because berdasarkan is being used as a preposition-like word meaning based on.

So the phrase is simply:

• berdasarkan = based on
• pemeriksaan keselamatan = safety inspection

You do not need yang here.
A structure with yang would be doing a different job, usually linking a noun to a relative clause.

In this sentence, berdasarkan pemeriksaan keselamatan is just a fronted phrase giving the reason or basis for the statement.

It is a noun phrase:

• pemeriksaan = inspection, examination
• keselamatan = safety

Together, pemeriksaan keselamatan means safety inspection.

This is a very common Malay pattern:

• noun + noun
• where the second noun modifies the first

So:

• pemeriksaan keselamatan = inspection related to safety
• literally something like inspection of safety

Malay often uses this compact noun+noun structure where English might use of or an adjective.

Malay usually puts the main noun first and the describing noun after it.

So:

• pintu = door
• keluar = exit / go out
• kecemasan = emergency

Together:

• pintu keluar = exit door
• pintu keluar kecemasan = emergency exit

This may feel reversed to an English speaker, because English often puts modifiers before the noun, while Malay often puts them after.

So instead of emergency exit, Malay builds it more like:

• door exit emergency

That is normal Malay word order.

Itu here functions like that or sometimes the, depending on context.

So:

• pintu keluar kecemasan itu = that emergency exit / the emergency exit

In Malay, itu often comes after the noun phrase, not before it.

Compare:

• rumah itu = that house / the house
• kereta merah itu = that red car
• pintu keluar kecemasan itu = that emergency exit

It often marks something specific and already identifiable.

Yes, in many contexts it can.

Malay does not have articles exactly like English a/an/the, so words like itu and ini often help show whether something is specific.

Depending on context:

• itu can mean that
• but in natural English translation it may also be best rendered as the

For example, in a building inspection context, pintu keluar kecemasan itu might naturally refer to a known exit, so English may translate it as the emergency exit even though itu literally points to that.

In Malay, a linking verb like English is/am/are is often omitted.

So:

• pintu keluar kecemasan itu selamat literally looks like
  that emergency exit safe
• but it naturally means
  that emergency exit is safe

This is completely normal.

Malay often forms simple statements by putting:

• subject + description

For example:

• Dia guru. = He/She is a teacher.
• Rumah itu besar. = That house is big.
• Pintu keluar kecemasan itu selamat. = That emergency exit is safe.

It is usually better not to use adalah before an adjective like selamat.

More natural:

• Pintu keluar kecemasan itu selamat.

In standard Malay grammar, adalah is more commonly used before noun phrases, while ialah also often links to noun phrases. In everyday usage, many speakers avoid both in simple sentences like this.

Because selamat is an adjective, the version without adalah is the safest and most natural choice.

Here selamat means safe.

Malay selamat has a wider range than English safe in some contexts. It can also appear in expressions related to well-being, greetings, or safety, for example:

• selamat pagi = good morning
• selamat jalan = have a safe trip / goodbye
• selamat = safe, unharmed

But in this sentence, because it is about an emergency exit and a safety inspection, the meaning is clearly safe.

Yes.

The main statement is:

• pintu keluar kecemasan itu selamat = the/that emergency exit is safe

The opening phrase:

• berdasarkan pemeriksaan keselamatan = based on the safety inspection

adds the basis or source for that judgment.

So the structure is roughly:

• basis/source phrase + main statement

This is common in formal Malay.

Yes, in many contexts you could also say:

• Pintu keluar kecemasan itu selamat berdasarkan pemeriksaan keselamatan.

This still means essentially the same thing.

However, putting berdasarkan pemeriksaan keselamatan at the beginning gives it a more formal, report-like tone and emphasizes the basis first.

So:

• fronted version = more formal, official, explanatory
• later version = also grammatical, sometimes more straightforward

The comma separates the introductory phrase from the main clause.

So:

• Berdasarkan pemeriksaan keselamatan, = introductory phrase
• pintu keluar kecemasan itu selamat. = main clause

This is similar to English punctuation in sentences like:

• Based on the inspection, the exit is safe.

The comma helps readability, especially in formal writing.

It sounds fairly formal or official.

Reasons:

• berdasarkan is common in reports, notices, and official explanations
• pemeriksaan keselamatan is a formal compound noun
• the whole sentence sounds like something from a building inspection report, safety notice, or official assessment

In casual speech, a person might choose simpler wording depending on the situation.

Because in Malay, many words can function in more than one category depending on context.

• keluar can be a verb: to go out
• but in compounds like pintu keluar, it behaves more like a noun or label: exit

This is very common in Malay. Context tells you how the word is functioning.

So:

• Saya mahu keluar. = I want to go out.
• Di mana pintu keluar? = Where is the exit door?

Same word, different role.

Usually emergency exit is the best translation.

That is because:

• pintu keluar specifically refers to an exit door
• adding kecemasan makes it an emergency exit

If you say emergency door in English, it sounds less precise and may not match the intended building-safety meaning.

So emergency exit is the most natural translation.
