protective garments

Protective clothing must be properly identified with its label.

As regards the design, when the suit consists of several protective garments (jacket and pants), the jacket must be of sufficient length to overlap at least 20 cm with the top of the pants. This minimum overlap must be maintained in all positions and movements expected during use. The pockets, if necessary in the suit, must be made of material according to the standard EN 15025 (FABRIC BEHAVIOUR WHEN PRESENTED WITH A FLAME).

Additional design requirements for protective garments with protection against splashes of molten metal (codes D and E):

  1. The sleeves of jackets and overalls, as well as the bottoms of the pants, they will not have hem.
  2. Outer pockets of the jackets and pants, except side pockets below the waist that do not form an angle greater than 10 ° with the side seam, must be covered by lapels at least 20 mm wider than the openings of the pockets.
  3. Patch pockets they must be manufactured from materials that meet the same levels of protection (A to F).
  4. Seams Overlaps on the outside of the garments should be facing down and secured in this position.
  5. The closures They must be designed with a protective flap on the outside of the suit. The maximum distance between the eyelets should be 150 mm.
  6. Zippers They must be stopped when they are completely closed.
  7. The fists they could be provided with closures to reduce their width.
  8. Neck opening It must be provided with closures.

In addition to the protective garments suit composed of jacket and pants, there are other textile garments commonly used in aluminum foundries, some are complementary and others mandatory for certain risks or specific jobs.

UNDERWEAR
It is recommended that the executioner, shirt, underpants and socks be flame retardant. More protection and proper thermal insulation.

ALUMINIZED SUITS
It is a garment to wear over the protective suit that is indicated for work very close to heat and the main risk that it must cover is that of radiant heat. In this case, the greatest protection against radiant heat C4 or C3 is sought. These types of garments must also have an optimum performance to D3 aluminum splashes. They are fabrics with less flexibility so more specialized clothing is recommended to improve ergonomics. One possibility is to combine non-aluminized fabrics that continue to comply with the rules of molten metal in the back parts. We will improve comfort.

PROTECTION BOOTS
It is a very important part of the clothing, they have to have good adhesion and the ability to protect against metal splashes. These are the main characteristics that it must have:

  • High adhesion sole, there may be oil in addition to aluminum powder or sands.
  • Non-metallic perforation resistant plate.
  • Dielectric protection (ESR).
  • Sealed seams.
  • Protection toe cap.
  • Breathable and waterproof.
  • It must comply with the norm of thermal risks and splashes of molten metal UNE EN ISO 20349: 2011 or the American ASTM F2413-11.

ALUMINIZED GLOVES
If gloves are needed, the use of aluminized gloves is recommended on the back of the hand. In the palm of the hand, fabrics that are more resistant to mechanical, cutting and friction hazards, such as para-aramides, can be used. The temperatures to which the glove should be subjected are 500 ° C.
