It is essential that companies use qualified forklift truck drivers who should only be expected to work within their capabilities. Not only is it necessary to use the right type of truck intended for a particular installation, it is also important to ensure that the layout of the racking system provides good access for that vehicle with adequate aisle widths free from obstruction.Pallets and decking can also be a potential cause of damage. Broken, or poor quality pallets can cause premature beam failure by putting outward pressure on the inside faces of the beams. Dropping heavy goods on to decking, overloading, or forcing items into place can cause them to weaken and become unstable. The decking being struck by access equipment, fork trucks and other heavy lifting equipmentcan cause other possible hazards.
Other rack accidents occur when the structures are not properly secured to the floor slab or when unsecured beams are dislodged. Improper loading, either by exceeding capacity constraints or not placing the pallet’s squarely on the decking can cause it to either tip off the front or back of the rack or to push another pallet off an adjacent rack in a double-deepsituation. In addition, post palets provide a series of pointloads for which beams may not be designed.
Safety Report Assessment Guide: Chemical warehouses - Hazards
2 Warehouse safety reports
HSE has issued guidance on the topics that should be addressed by a COMAH safety report, but Occupiers are not obliged to follow the order suggested. In fact it makes more sense to describe a warehousesite first and then the stocks of chemicals held, therefore this is the order of the information presented in this document.
2.1 Site description
The safety report assessment manual lists all the aspects that should be addressed in the site description. This guidance make reference to the features that are important for a risk assessment:-
* Site location with maps.
* Plan of site.* Brief site description.
* Nature of the warehousing operation.
* Indication of nature and location of materials stored. This should include details of area set aside for segregated storage of flammable liquids, highly toxics, self -reactives etc.
* Site drainage and sewage systems with plans.
* List of neighbours with hazard potential.
* Brief description ofsurrounding countryside (a much fuller description should be presented in a separate section dealing specifically with the site environs and the environmental survey).
* A description of nearby centres of population. This should include residential areas and places of work.
* The maximum number of persons on site and their likely locations.
* Wind rose data for the site.
* Description ofthe underlying and surrounding geology and hydrology if it is relevant.
* Description of nearby transport systems.
* Groups of nearby vulnerable people.
* High voltage overhead power lines.
* Nearby underground pipelines.
2.2 Hazardous substances on site
Agrochemical warehouses tend to contain substances with risk phrases that span the complete range given in the CHIPRegulations. A safety report must consider the hazards from all substances in a warehouse if the warehouse contains sufficient dangerous substances to bring it under the COMAH top tier regulations.
The aggregation rules, which allow occupiers to test which warehouses meet this criterion are as follows: -
* The threshold quantities listed in Schedule 2 Named Substances refer to pure substances....
