وفقا لشهادة السلامة، نظام الرش الآلي صالح للعمل.

A careful MSA reading is:

وَفْقًا لِشَهَادَةِ السَّلَامَةِ، نِظَامُ الرَّشِّ الآلِيُّ صَالِحٌ لِلْعَمَلِ.

A rough pronunciation guide is:

wafqan li-shahaadati s-salaamah, nizaamu r-rashshi al-aaliyyu saalihun lil-`amali

In normal Arabic writing, the short vowels are usually omitted, which is why the original sentence appears without these marks.

وفقًا لـ means according to, in accordance with, or based on.

So:

• وفقًا لشهادة السلامة = according to the safety certificate

This is a very common formal MSA expression, especially in reports, official statements, and technical writing.

Because وفقًا is normally followed by لـ.

So the pattern is:

• وفقًا لـ + noun
• طبقًا لـ + noun
• استنادًا إلى + noun

Here, لِشهادةِ means according to the certificate.

Grammatically, the لـ is a preposition, so it makes شهادة genitive.

Because this is an iḍāfa construction, often called a possessive or noun-link construction.

• شهادة = certificate
• السلامة = safety
• شهادة السلامة = the safety certificate

In an iḍāfa:

• the first noun usually does not take ال
• the second noun can make the whole phrase definite

So شهادة السلامة is definite because السلامة is definite.

This is also built around an iḍāfa:

• نظام = system
• الرش = spraying / sprinkler action
• نظام الرش = sprinkler system / spraying system

Then الآلي is an adjective added after the whole iḍāfa phrase:

• نظام الرش الآلي = the automatic sprinkler system

So the structure is basically:

• نظام الرش = sprinkler system
• الآلي = automatic

It describes نظام.

Even though it comes after الرش, it refers to the whole phrase نظام الرش and agrees with the head noun نظام.

That is why it is:

• masculine singular
• definite
• nominative in a fully vowelled reading

This is normal in Arabic: an adjective modifying an iḍāfa phrase comes after the entire phrase, but it still agrees with the first noun, the head noun.

Because نظام is the first part of an iḍāfa.

In Arabic, the first noun in an iḍāfa normally does not take ال. Its definiteness comes from what follows.

So:

• نظام رش = a sprinkler system / a spraying system
• نظام الرش الآلي = the automatic sprinkler system

The phrase is definite because the second part is definite.

There is no separate word for is in this kind of Arabic sentence.

Arabic often uses a nominal sentence in the present tense with no expressed copula. So:

• نظام الرش الآلي صالح للعمل
• literally: The automatic sprinkler system fit for operation
• natural English: The automatic sprinkler system is fit for operation

So the idea of is is understood, not spoken.

Because the subject is نظام, which is grammatically masculine singular.

So the predicate adjective must agree with it:

• نظام ... صالح = a system ... fit/suitable
• if the subject were feminine, you would expect صالحة

For example:

• الآلة صالحة للعمل = The machine is fit for operation

صالح means fit, suitable, valid, or serviceable, depending on context.

With لـ, it often means:

• fit for
• suitable for
• ready for

So:

• صالح للعمل = fit for operation, ready for use, or serviceable

Here العمل does not mean job/work in the employment sense. In this context it means something more like operation, functioning, or use.

The sentence has two main parts:

1. وفقًا لشهادة السلامة

   • a fronted prepositional phrase
   • it gives the source or basis of the statement: according to the safety certificate

2. نظام الرش الآلي صالح للعمل

   • the main nominal sentence

Inside that main sentence:

• نظام الرش الآلي = the subject
• صالح للعمل = the predicate

So the overall structure is:

• According to the safety certificate,
• the automatic sprinkler system is fit for operation.

In the fully vocalized version:

وَفْقًا لِشَهَادَةِ السَّلَامَةِ، نِظَامُ الرَّشِّ الآلِيُّ صَالِحٌ لِلْعَمَلِ

the endings reflect normal case rules:

• وَفْقًا: accusative adverbial form
• لِشَهَادَةِ: genitive because of the preposition لـ
• السَّلَامَةِ: genitive because it is the second noun in an iḍāfa
• نِظَامُ: nominative because it is the subject
• الرَّشِّ: genitive because it is the second noun in an iḍāfa
• الآلِيُّ: nominative because it is an adjective describing نظام
• صَالِحٌ: nominative because it is the predicate
• لِلْعَمَلِ: genitive because of the preposition لـ

A learner does not need to pronounce all of these endings in everyday reading, but understanding them helps a lot with sentence structure.
