Choose an empty first aid box against your approved contents list and its intended location. Confirm four things separately: closed external size, usable compartment space, room to open the case and clearance to remove it from any bracket. Ask the supplier to confirm the exact model and included accessories. MedSphere’s ABS box is supplied empty; contents require a separate enquiry.
1. Size the case around the approved contents
A box can look generous in a photograph and still be the wrong shape for your supplies. Begin with the contents schedule approved by your responsible safety professional. Record the quantities and the dimensions of the actual packaged items, especially the largest or most awkward pack. A product’s unpacked size will not tell you whether its wrapper fits.
UK HSE guidance bases kit contents on a first aid needs assessment. That supports starting with the required supplies, rather than selecting whatever fits an attractive box. It is UK guidance, not a contents rule for workplaces in the UAE, Saudi Arabia, Oman or Qatar.
If the contents list is still undecided, mark the box size as provisional. Reducing the approved contents simply to fit a smaller case sends the purchasing decision in the wrong direction.

2. Request four measurements, not just “large”
Ask for a drawing or written dimensions for the exact quoted model. External width, height and depth answer whether the closed case fits its location. They do not describe the room left inside after dividers, trays and the lid are taken into account. Request usable dimensions for the compartments you intend to fill.
Opening clearance is a separate check: can the lid or door reach its usable position without hitting a shelf, another cabinet or a nearby fitting? A removable case also needs enough room for its particular release movement. A wall position that accommodates a closed box may leave no room to lift or slide it off.
For a first layout check, draw the supplier-confirmed compartment outlines on paper and place the unopened packs within them. This can reveal an obvious footprint mismatch, but it cannot establish depth or closing clearance. Ask for a packing demonstration or suitable sample before approving a fit that remains uncertain. Keep sterile packaging sealed.
For example, imagine two cases with similar external dimensions. One has a divider across the space needed by your largest wrapped item; the other does not. The first may fail the layout check despite looking the same size. This is an illustrative purchasing scenario, not a measurement or test of the catalog box.
3. Treat the bracket as part of the specification
Reliance Medical’s Aura3 FAQ describes a case that slides onto its own fixing bracket. This manufacturer example shows why removal movement belongs in a location check. It does not establish how MedSphere’s catalog box mounts, or whether an existing bracket is compatible.
Ask which bracket or fixing arrangement the quoted model uses, what hardware is included and which installation instructions apply. Give the site’s responsible installer the wall or support details. A carrying handle is not evidence of wall-mount compatibility, and a photograph is not a mounting drawing.
For a replacement purchase, record the old case and bracket references if known. Request written compatibility confirmation before assuming the new box will reuse the existing fixing points. If the answer is unavailable, leave compatibility unresolved in the comparison sheet.

4. Check access and protection separately
Decide what needs to be accessible at the first aid station and what belongs in reserve storage. Cederroth’s Double Door cabinet, reference 290900, illustrates a deliberate separation: an outer first aid panel and a lockable inner refill compartment. That arrangement belongs to that specific model; it is not a feature promised for the MedSphere box.
Ask the safety lead to approve the proposed location and access arrangements for every shift. If a lock is specified, establish what it secures and how access will work. Do not add a lock to the order without resolving that question.
Describe the actual storage environment, including any dust, splash or heat exposure. Request the manufacturer’s documented suitability and storage limits for both case and contents. “ABS plastic” is a material description; by itself it provides no evidence of a tested dust or water protection rating. Do not infer weatherproofing from the appearance of clips or a seal.

5. Keep unconfirmed details visible in the enquiry
Complete the worksheet below with your measurements and mark each supplier response as confirmed, excluded or unresolved. Include the drawing or model reference used for the decision so a later substitution does not silently change the fit.
For MedSphere’s empty ABS box, request usable dimensions, compartment details and mounting information in the quote; these are not established by this guide. List any first aid supplies separately. Add the quantity, delivery country and city, then paste the requirements into the quote form with your name, phone and email. The team must confirm specifications, availability and delivery before an order is agreed.

Questions before you order
Are external dimensions enough to choose an empty first aid box?
No. Also request usable compartment dimensions, opening clearance and any bracket-removal clearance. Check the actual wrapped supplies against the interior layout; similar external dimensions can hide different internal arrangements.
Does an ABS first aid box automatically have a waterproof rating?
No rating should be inferred from the material name. Ask for model-specific manufacturer documentation if dust or water protection is required. This guide assigns no protection rating to the MedSphere catalog box.
Can I reuse the wall bracket from my old first aid box?
Only after the supplier confirms compatibility with the exact replacement model. Send the old model and bracket references if available, and keep the mounting question unresolved until it is answered.
Are the manufacturer examples the products sold by MedSphere?
The Reliance and Cederroth references explain different design choices. They do not identify the manufacturer of MedSphere’s catalog box or confirm supply of those referenced products. The listed MedSphere ABS box is empty; ask for its own specifications and any contents separately.
