Load Notices
I have a query regarding sections of racking which have different beam lengths within the same run, i.e. some bays are two pallets wide; some are one pallet wide. My query is whether these sections of racking should have more than one load notice to reflect this? We have had three SEMA approved inspectors on site doing racking inspections over the last 18 months and none of them have flagged this up, however it was raised when we had a recent visit from the HSE.
The load notice should provide sufficient information to enable the rack to be used in accordance with the designer’s intentions.
If you have racking with different configurations then this information could be transmitted by providing a different load notice for each configuration or, alternatively, by using a load notice that gave an acceptable solution for all the configurations – what an engineer might call a “conservative” or “lower-bound solution”.
There is more information about load notices on the SEMA website https://www.sema.org.uk/load-notices/load-notices-video-short-version
I know that I need to have a load notice on my racking. Is it OK to have it in black and white?
Racking and shelving are considered to be work equipment and, therefore, are covered by the Provision and Use of Work Equipment Regulations (PUWER) which requires, amongst other things;
- That the equipment should be inspected and maintained in good working condition,
- That people operating work equipment are given adequate training in the correct use of the equipment,
- That employees are given necessary health and safety information.
The load notice is a safety sign and, as well as giving loading information, also gives important instructions and information about the general usage of the racking e.g. prohibitions about altering or climbing the racking as well as an instruction to report damage and signposts to information sources.
Paragraph 634 of the HSE publication “Warehousing and storage – A guide to health and safety” HSG76 states that “Racking should have a clear unambiguous notice securely fixed to it, stating the maximum load together with any necessary specified load configurations”, and goes on to refer to the SEMA publication on Load Notices.
The load notice is a safety sign and, if fitted after 1996, must comply with safety sign legislation i.e. the Health & Safety (Safety Signs and Signals) Regulations 1996. These regulations require that the safety sign must follow certain rules, for example, with respect to the shape and colour of the sign.
Therefore, the SEMA load notice must be in colour. A SEMA Approved Rack Inspector (SARI) will categorize a monochrome load notice as an Amber risk.

Is it a legal requirement to follow the format of the SEMA Load notice?
Racking and shelving are considered to be work equipment and, therefore, are covered by the Provision and Use of Work Equipment Regulations (PUWER) which requires, amongst other things;
- That the equipment should be inspected and maintained in good working condition,

Paragraph 634 of the HSE publication “Warehousing and storage – A guide to health and safety” HSG76 states that “Racking should have a clear unambiguous notice securely fixed to it, stating the maximum load together with any necessary specified load configurations”, and refers to the SEMA publication on Load Notices.
The load notice is a safety sign and, as well as giving information about the Safe Working Load (SWL) of the racking, also gives important instructions and information about the general usage of the racking. As the load notice is a safety sign it must comply with safety sign legislation i.e. the Health & Safety (Safety Signs and Signals) Regulations 1996 and these regulations require that the safety sign must follow certain rules, for example, with respect to the shape and colour of the sign.
So, the SEMA load notice is the easiest way for an employer
- to comply with HSE recommendations
- to satisfy their legal obligation to supply the information about safe operation of the racking
- to follow the safety sign legislation
Whilst it would be ill advised to reduce the information on the load notice your supplier might consider it helpful to add some further information e.g. the design code used, the beam/upright designation etc. and, provided that this does not impair the purpose of the load notice, this should be satisfactory.

What is the approved way to fit a load notice?
The recommended way to fit a load notice depends upon the product to which you are fitting the load notice. In the case of adjustable pallet racking it is a common practice to fit the load notice to the frame bracing, for shelving it will often be fitted to the shelving frame, for cantilever racking the notice will generally be fitted to the column and for mezzanines to a main beam on the perimeter of the floor.
If the load notice is stuck (glued) to the storage equipment there is unlikely to be any problem as far as the storage equipment is concerned, however, the glue might fail and the load notice fall off. If a screw fixing is chosen then care is necessary as it is possible to affect the structural integrity of the equipment if unsuitable holes are drilled and some manufacturers will therefore, prohibit drilling holes in certain racking components, or will only permit holes up to a certain diameter and/or in particular positions in the member.
In all cases the supplier/manufacturer should be consulted for a preferred fixing method and location.
Inspections
We are looking at getting some new pallet racking which will be installed by a company and not ourselves. My question is once it is up I know we will have to do weekly checks on it but will an official check need to be done on it by somebody or is the installation enough?
Whether you require a third-party sign-off depends on the hand-over certification and the competence of the installer of the racking.
If it is installed by a company who are competent to install the racking and they provide suitable documentation that confirms that the racking has been installed in accordance with SEMA and the racking manufactures requirements, then an additional official check may not be required.
Please note there are 3 types of inspection:
(a) Immediate Inspections
Immediate reporting of all damage and areas of concern to a ‘Person Responsible for Rack Safety’ (PRRS). This should follow a documented procedure with records kept on the action taken as a result of such reports. All warehouse staff should be encouraged to report damage immediately.
(b) Regular Inspections
The PRRS should ensure that documented inspections are made at weekly or other intervals based on a risk assessment on the operating conditions of the warehouse. The inspection should be carried out by a suitably trained individual. The SEMA one day rack safety awareness training course is considered appropriate training for the Regular Inspection.
(c) Expert (Annual) Inspection
The third level of inspection is a yearly, or twice-yearly inspection (period depending on the risk assessment) of the rack carried out by a qualified Rack Inspector. Such an inspection will result in a documented report which will identify damage and will also provide guidance and comment on other warehouse activities. The Expert inspection should be carried out by a technically competent person. It is recommended that this inspection is carried out by a SEMA Approved Rack Inspector (SARI).
We have a warehouse containing high level pallet racking and use this to store palleted products. What are the recommended inspection times for this type of racking, is it annual by a competent person and if so would the competent person be expected to have undertaken some form of training on racking inspections to demonstrate competency?
SEMA recommend that racking inspections should be carried out on an onion skin approach. First of all the equipment operators are the first line of defence and should always be encouraged to report damage as it occurs. In order to achieve this there should not be a blame culture or nothing will ever be reported and also the operators need to see that things happen as a result of reporting some damage or again nothing will be reported.
The second line of defence should be a supervisor’s weekly patrol inspection carried out with the express purpose of checking the racking. This should be done at weekly intervals normally at a standard walking pace keeping documented records of the inspection and action points resulting from the inspection. Out of interest SEAM run one day ‘rack awareness’ courses at West Bromwich about once every two weeks where a supervisor can obtain some training about what is required from inspections.
The final level of protection is the formal inspection that should be carried out every 6 or 12 months depending on the level of activity in the warehouse. A high throughput warehouse operating 24/7 would be at the lower end of the range and indeed might need inspections every three months in some circumstances. In slower moving single shift environments, the inspection could be at the top end of the scale. This would be the competent person inspection that you refer to and while HSE are keen to endure a high standard in such inspectors they will not insist that it is work that can only be done by people with a certain level of qualification. SEMA run a SARI (SEMA Approved Rack inspector) qualification whereby a rack inspector can demonstrate the level of training and competence to a client and a number of us who carry out such surveys on a regular basis have passed through this course which is of a very high standard and has a significant failure rate. If you need such a person you will find an up to date list of qualified SARI inspectors together with contact details on the SEMA web site www.sema.org.uk
Having said all the above it is possible for an inspector to demonstrate his competency by means other than this course however that is a matter between the inspector and the client.
What racking inspections do you recommend and at what frequencies? I have been informed that if any repairs to the racking have been done by unqualified persons, i.e. our maintenance personnel who are perfectly able but not specifically trained in repairing racking, then should an accident occur, involving the racking collapsing or some such, we would not be insured. Is this correct? Similarly, if the racking was erected by unqualified/untrained persons, would the same be true/rate competency?

SWL FAQs
I would like to know if we need to place a Safe Working Load notice on every Racking aisle or would one load notice per Racking configuration suffice?
The issue is that you need to inform anyone who is using the rack with carrying capacity information and anything else they need to know to use the rack safely.
In theory therefore if all your racking in the warehouse was to the same configuration and all fork trucks came into and out of the warehouse through one single door it would be adequate to have only one sign adjacent to the door as all drivers would pass this sign before placing pallets in the rack.
Life is rarely that simple however, but it does boil down to your risk assessment. If you have a lot of racking the same, then a sign on every other rack or even every 3rd run might be acceptable. If there are differences between adjacent runs where drivers might become confused, then you would need to anticipate this and have more signage so there is no excuse for operators making mistakes and blaming the lack of signage as the cause.
Racking ID & Safe Working Loads
We use a racking system provided by a reputable manufacturer. Currently we operate with a 2.7 metre span and have all the safety data required for this configuration. We now wish to create a bay with a 3.3 metre span – can SEMA give me the SWL for this span?
Unfortunately SEMA do not have the load data for the various manufacturers’ propriety products. Your best course of action is to contact the manufacturer of your racking system. Either they, or their appointed distributor, should be able to give you the information you require, particularly as you will have to purchase 3.3 metre beams to accommodate this new bay size. If this approach fails, you will need to obtain the services of Specialist Engineering Consultant to calculate the data.
When does Shelving become Racking?
What is the difference between Racking and Shelving?
A key difference between racking and shelving is that shelving is almost always loaded by hand and the weight of the individual goods carried is comparatively low (typically less than 25kg), furthermore the total weight carried in a bay of shelving will typically be less than 4T. Racking is typically loaded by machine (forklift truck or crane) and the unit loads carried are typically heavy, i.e. many hundreds of kg; pallet weights exceeding 1T are common. The weight of goods carried in a bay of racking can exceed 40T in extreme circumstances. Racking is typically, therefore, a heavier duty system than shelving utilising larger members and thicker material.
If a racking structure has some sort of flat surface (decking, panels etc.) positioned on the beams then (with appropriate design) it is possible to use a racking structure as shelving. It is impossible to safely use a shelving structure as racking, i.e. storing pallets etc.
SEMA defines racking as:
A skeleton framework of fixed or adjustable design to support loads generally without the use of shelves. The term racking is usually qualified, e.g. Pallet Racking, Tyre Racking, Drum Racking etc.
Adjustable pallet racking is defined as:
A system of upright frames that are connected by horizontal beams to provide pallet storage levels, which can be adjusted vertically.
SEMA defines Shelving as:
A series of load carrying surfaces (shelves) supported by upright frames
Unfortunately, many people are not particularly precise in the use of these terms and will interchange them, which can lead to confusion.
We have several shelving/racking units (nothing on the scale of large warehouse racking systems) located in offices for archive and a small storage unit within our Estate. My knowledge on whether they require a formal yearly inspection and/or frequent period checks by a competent person is lacking and would like to ask for your assistance.
To your specific point, it boils down to your risk assessment as to what needs inspecting. You can have office shelving which can be classed as furniture and as long as you don’t have people pulling such items as loaded hand pallet trucks into the offices and the potential of impact and collapse can be treated in the same way as you would normal office furniture.
However, archive stores where the possibility of moving trolleys being used is much greater and the weights being stored could possibly also be much greater. A tidy up in such areas from time to time would be useful as the main issue is I doubt if you know what weight you are imposing on the shelving and suspect there are no safe working load signs on the shelving to allow your operatives to understand what loads they can safely place on the shelves in order to use the system.
There is probably some work to be done here on safe load signage and understanding the imposed loads that you have.
