Storage of glaze, paintings and dissolvent in cabinets protected
How know when a liquid is flammable?
All the chemical products have to come accompanied by his ‘Index card of Data of hygiene'. The provider of chemical products is forced to deliver it in the first purchase of product and the review of the same every time that it was modified.
In this index card of data of hygiene, in the section 9 find the characteristics fisico-chemical of the substance or chemical product. If this point of inflamabilidad is not upper to 60 °C find us with a flammable liquid (according to the new classification of the Regulation CE 1272/2008 on classification, labeling and packaging of substances and mixes (from now on CLP)
According to this new classification in the index card of data of hygiene find the following indications of danger:
- H224: Liquid and sequipment extremely flammable
- H225: Liquid and sequipment very flammable
- H226: Liquid and flammable sequipment
On the other hand, the CLP also considers flammable the specific diesel, fuel diesel and light oils of heating in spite of having a point of inflamabilidad upper to the 60 °C.
If the ready or mix in place to be classified according to CLP still has the classification according to the ancient criterion (RD 255/2003, of 28 February 2003, by which approves the Regulation on classification, packaging and labeling of ready dangerous) the sentences of risk that will appear in the ‘Index card of Data of hygiene' are the following:
- R10: Flammable
- R11: Easily flammable
- R12: Extremely flammable
Finally, a flammable liquid will be included inside the Class 3 of the ADR (European Agreement on the international transport of dangerous loads by terrestrial road)
In addition to these sentences, will be able to differentiate a ready or flammable substance because it will carry the pictogram that like this the difference:
How store small quantities of flammable liquids?
In the ‘Index card of Data of hygiene' find data like the compatible constructive materials with the chemical product to store, the incompatible chemical products with him and the means of extinction adapted.
On the other hand is precise to take into account that a flammable liquid badly stored can be a potential source of fire and that in case of fire generated by other causes can ocasionar that it magnify the same.
Is precise thus store properly these liquids. The Regulation of Storage of Chemical Products (RD 379/2001 modified by the RD 105/2010, from now on APQ), and in particular the Complementary Technical Instruction MIE-APQ 01 (from now on ITC MIE APQ-01) is of application from 50 L of flammable and besides inside his field of application includes also to the products fuels with a point of inflamabilidad until 150 °C.
In the case of small containers, the solution of storage simpler is a cupboard protected.
Which requirements has to fulfil a cupboard protected?
From 2005 the norm that dictates the requirements of a cupboard protected is JOINS it-IN 14470-1. This norm substitutes to the previous A 1634-1 and is specific for cabinets protected for flammable liquids.
The different elements of the cupboard protected have to fulfil some true characteristic so that this can happen the proof of fire and therefore can be cataloged like RF ‘x' minutes.
The Regulation APQ demands like minimum that the cabinets protected have a resistance to the fire of 15 minutes, this is due to the fact that this is the minimum classification for this type of equipment. Nevertheless the Norm JOINS- IN 14470-1 clears that it is precise to choose between the different types of Cabinets Protected in function of the particular circumstances of each installation. It is precise that the cupboard of hygiene provide us the necessary time stops:
- Desalojar to the personnel that works in the installation affected
- That the firemen access to the installations to be able to extinguish the fire
Parts of a cupboard protected
The different elements have to have the following characteristic:
How know that ‘my' cupboard protected fulfils these requirements?
As it has commented previously, the cupboard has to be subjected to a proof of fire by what all the cabinets have to have a Certificate of Proof in which it certify the resistance to the fire of the same. It is precise to request this certificate to the manufacturer or supplier of the team, and verify his validity.
Exist in the market cabinets that say protected and that are not it, for example:
- Cabinets with resistance to the fire of material (for example EI-60) but without having happened the proof of fire that asks JOINS it-IN 14470-1
- Cabinets that designate protected but that do not have RF, this is due to the fact that in rules like the one of EE UU allow Cabinets without RF, but are not valid to justify them like Cabinets Protected according to the ITC MIE APQ 01 in Spain
- Cabinets that do not fulfil the requirements of JOINS it 14470-1 although they present us a Certificate. They have identified cabinets protected that they do not fulfil the requirements demanded. It exists a web in which they can consult the manufacturers and some of the suppliers of these equipment: www.icsms.org, the European database more complete on products of consumption and professionals that have been testados and has tested that they do not fulfil the standards that demand the authorities in this regard.
