The document, section by section, so you know what you are buying before you buy it.
What is covered, what is not, and who the operator is. Also what was not accessible on the day, which matters if it comes up later.
Every substance, quantity, where it is held and in what. Taken from what is actually on site rather than from what the purchasing list says.
Each point where a flammable atmosphere can be released, graded continuous, primary or secondary. This is the part the zoning is built from and it is the part most often skipped.
Natural or mechanical, its availability and its effectiveness. Ventilation is what turns a release into a zone of a particular size.
The zones, with a drawing and dimensions. Zone 0, 1 and 2 for gases and vapours; 20, 21 and 22 for dusts. Where the assessment finds no zones are needed, the reasoning is recorded instead.
Electrical and non-electrical, including the ones people forget: hot surfaces, static, mechanical sparks and mobile phones.
What you already have and whether it is doing what you think it is doing.
Numbered, prioritised and dated. Legally necessary items separated from good practice.
If a document cannot do those five things, it has not earned its fee whatever it cost.
We do not pad assessments with regulation text you can read yourself, and we do not zone an entire building because it is quicker than working out where the release sources are. Over-zoning is not the safe option: it makes the document useless, it forces unnecessary equipment spending, and it teaches everyone on site to ignore the drawing.
For a single-substance site such as a small workshop with a solvent store, often twenty to thirty pages including the drawings. A multi-process site runs longer. Length is not the measure: a short assessment that identifies every release source is worth more than a long one that repeats the regulations back at you.
Yes. A zoning drawing with dimensions is the part an inspector, an installer and your insurer will all want, and it is the part most commonly missing from assessments people bring us.
Usually. What matters is that the required elements are there and findable, not the house style. If your business already has a format that people actually read, that is worth keeping.
It should tell you what is legally necessary, what is good practice, and what is optional, and rank the actions by urgency. If everything is urgent, nothing is, and you cannot plan around it.
No. We write the assessment and you buy whatever it says you need from whoever you like. There is no incentive for us to find a problem that needs an expensive product.
The duty, in plain terms.
What moves the price, and what does not.
The drawing, and how the zones are worked out.
No charge for the conversation. Most quotes go out the same day.
