This guide deals with protective clothing that should be worn by all workers and employers who use welding processes or related techniques, regularly or occasionally. The techniques related are operations that present risks similar to those of welding, such as oxycutting, flame or arc gouging, and thermal spraying.
The choice of these protective equipment must also take consideration of work processes and situations. The ISO 11611: 2015 standard is built on two classes of exposure, depending of the hazards risk. These classes determine the needs for protection depending of the exposures from hazards, such as, the volume of: sparks; molten metal ; radiant heat that worker are exposed during the tasks.
Class 1 protective clothing
Suitable for welding techniques and work situations that cause small amounts of sparks and droplets of molten metal and low radiant heat.
Class 2 protective clothing
Resist more sparks and droplets of molten metal. They offer greater protection against radiant heat.
To ensure that the garment conforms to the standard, BIGBILL ensures, among other things, that:
• all tests required by the standard are made as prescribed. Where the tests are carried out by a subcontractor of the certification body, that subcontractor must have demonstrated his competence and performance in carrying out those tests;
• the performance criteria of each test are respected;
• the design and manufacturing requirements of the standard are met; (See down there)
• the manufacturer’s labels and instructions give all the information required by the standard; (See down there)
• The manufacturer maintains a quality system that ensures consistency and conformity of the product on an ongoing basis.
The ISO 11611: 2015 standard requires that protective clothing has one or more labels that provide, in a visible and durable manner, essential information on their origin, their
features and cleaning instructions. Mark the following label on your protective suit:
Fabrics and materials:
The fabrics and materials that make up the protective clothing are ISO 11611 certified and guarantee resistance to flame propagation, do not produce inflamed or melted debris, and residual incandescence and flame persistence times do not exceed 2 seconds. They resist the heat of molten metal splashes and offer a barrier against radiant heat. The molten metal does not adhere to the materials.
The design of the protective clothing:
Here is the design element of the protective suit
1) The neck is protected by a mandarin collar with closure
2) The closures are covered with a protective flap
3) The pockets are provided with flap wider than the opening
4) The side pockets form an angle of not more than 10°
5) The coverall has side slots, which are provided with a closure means.
6) The sleeve is provided with a closure to reduce its width. The closure and folds are then under the wrist.
More: All snap closures are covered with fabric by the inside and the outside.
