I og med at brandøvelsen begynder klokken ti, læser vi evakueringsinstruksen.

I og med at means since, as, or given that. It introduces the reason or background for the main clause.

So in this sentence, it gives the reason for læser vi evakueringsinstruksen.

It is a fixed expression, so it is best learned as a whole rather than translated word by word.

It is perfectly normal Danish, but it can sound a bit more formal or written than fordi.

Compare:

• Fordi brandøvelsen begynder klokken ti, læser vi evakueringsinstruksen.
• I og med at brandøvelsen begynder klokken ti, læser vi evakueringsinstruksen.

Both are understandable, but i og med at often has a slightly more official or explanatory tone, a bit like given that in English.

This is because Danish main clauses usually follow the V2 rule: the finite verb comes in the second position.

Here, the whole subordinate clause I og med at brandøvelsen begynder klokken ti comes first. That first chunk takes up position 1, so the finite verb of the main clause must come next:

• Position 1: I og med at brandøvelsen begynder klokken ti
• Position 2: læser
• Then the subject: vi

So læser vi is correct here.

If the sentence started directly with the subject, then you would say:

• Vi læser evakueringsinstruksen.

Because i og med at introduces a subordinate clause, and subordinate clauses in Danish usually have normal subject-verb order:

• brandøvelsen = subject
• begynder = finite verb

So:

• I og med at brandøvelsen begynder klokken ti ...

This is different from the main clause, where Danish uses V2 word order.

Danish often uses the present tense for scheduled future events, just like English can.

So:

• brandøvelsen begynder klokken ti

means the fire drill starts at ten, even if ten o’clock is still in the future.

This is very normal with timetables, plans, and scheduled events.

In Danish, time expressions often work directly with klokken + the time:

• klokken ti = at ten o’clock

So after a verb like begynder, you can simply say:

• begynder klokken ti

You do not need a separate preposition here.

Brandøvelsen is a compound noun:

• brand = fire
• øvelse = exercise, drill
• -n / -en = the definite ending

So:

• brandøvelse = fire drill
• brandøvelsen = the fire drill

Danish forms many nouns by combining smaller words into one long word.

This is also a compound noun:

• evakuering = evacuation
• instruks = instruction, directive
• -s- = a linking s
• -en = the definite ending

So:

• evakueringsinstruks = evacuation instruction / evacuation guidelines
• evakueringsinstruksen = the evacuation instruction(s)

The -s- in the middle is very common in Danish compounds and does not usually need to be translated separately.

Danish sometimes uses a singular noun where English might prefer a plural, especially when talking about one document, one set of rules, or one instruction text treated as a single unit.

So evakueringsinstruksen can naturally mean something like:

• the evacuation instructions
• the evacuation procedure
• the evacuation guideline/document

The exact English wording depends on context, but the Danish singular is completely normal.

The comma marks the end of the subordinate clause and the beginning of the main clause.

So the structure is:

• I og med at brandøvelsen begynder klokken ti = subordinate clause
• læser vi evakueringsinstruksen = main clause

The comma helps show that boundary clearly.

Yes, in many situations you could.

For example:

• Fordi brandøvelsen begynder klokken ti, læser vi evakueringsinstruksen.

That would still mean roughly the same thing.

The difference is mainly tone:

• fordi = more straightforward, everyday because
• i og med at = more formal or explanatory, closer to since/given that

So both are possible, but they do not always sound exactly the same in style.
