General requirements in the design of protective garments in aluminum foundries
The suit must be properly identified by its label
With regards to design, when the suit is made up of two pieces (jacket and trousers), the jacket must be long enough to overlap the top of the trousers by at least 20 cm. This minimum overlap must occur in all positions and movements expected during use. The pockets, should they be necessary in the suit, must be made from material complying to regulation EN 15025 (flame propagation).
Additional requirements for the design of protection suits against splashes of molten metal (Codes D and E):
As well as the suit, made up of jacket and trousers, there are other textile garments that are regularly used in aluminium foundries, some are complementary and others are mandatory for certain risks or specific tasks.
We recommend that the balaclava, under shirt, underwear and socks be flame-proof. More protection and correct thermal insulation.
These are to be worn over protection suits and are indicated for jobs very close to heat, where the main risk to cover is radiant heat. In this case, the objective is maximum radiant heat protection (C4 or C3). This type of garments must also have an optimum behaviour against aluminium splashes (D3). These fabrics have less flexibility, so it is recommended that they be specially tailored for greater comfort. One possibility is to combine non-aluminised fabrics that still comply with the molten metal regulations in the back of the garment to improve comfort.
A very important part of the clothing; they must have good adherence and the ability to protect against metal splashes. These are the main characteristics that they must have:
They must comply to thermal risk and molten-metal-splash UNE EN ISO 20349:2011 or US ASTM F2413-11 regulations.
If gloves are required, aluminised gloves are recom¬mended for the back of the hand. The palm of the hand can be covered with fabrics that are more resistant to mechanical risks, cuts and friction, such as para-aramids. The temperature that gloves must withstand is 500 ºC.
