Hand Protection • Introduction to Hand protection • Hand injury hazards at work sites • Protection suggested • Glove classification • Standards followed • Case Study • Choosing the right glove • Products from Mallcom • Summary April 12
Hands are the chief organs for physically manipulating the environment, used for both gross motor skills (such as grasping a large object) and fine motor skills (such as picking up a small pebble). • The fingertips contain some of the densest areas of nerve endings on the body, are the richest source of tactile feedback, and have the greatest positioning capability of the body; thus the sense of touch is intimately associated with hands. April 12
The hand A complex tool The palm A PERFECT DEXTERITY The back • 27 bones, 40 muscles • 3 nerves • skin. • 1 Accidentover 3 concerns hands • Around 8 millions days of work lost per year • 40% of the total work accidents April 12
Hand Hazards can be broadly categorized into • Mechanical hazards • Cutting • Punctures • Crushing • Pinches • Rotating Equipment • Vibrating Equipment • Environmental Hazards • Extreme Temperatues • Electrical Hazards • Contact with skin irritant substances Cuts Punctures Rotating Equipment Vibrating Equipment Pinches April 12

Material in gloves 1. Leather FULL GRAIN Types of leather: DERME SPLIT • Cowhide leather • (Full) GRAIN leather: external part of the leather Advantages : dexterity, comfort and supplesness • Goatskin leather: full grain leather only • Lambskin leather: full grain leather only • SPLIT leather: Internal part of the skin Advantages : lower cost, excellent resistance to abrasion • Pigskin leather: lower price April 12
Material in gloves Tanning transforms the rough natural skin of the animals into leather, which is Rot-Proof and Non-Permeable and renders the leather supple. GrainThe grain layer is the outermost external side where the hair used to be. This grain-textured layer is regarded as the most expensive. SplitThis layer is the rougher internal side of hide. In the glove industry, it may be subcategoried as: Side Split This came from the back and side portions of the animal. The hide is densest here, yielding consistently durable grade leather. Shoulder Split This came from the shoulder area where the hide is less uniform in density and appearance. The result is less durable, but more affordable leather. Belly (Economy) Split The belly area yields the thinnest and least durable leather. April 12
Material in gloves Parts & Types of a leather glove Driver gloves – Designed to resist vibration and provide maximum comfort Work gloves are designed to give comfort and ventilation, well padded on palm and breathable back.

EN Regulation 89/686/CEE Manufacturers Directive • The standard defines 3 categories of PPE according to the level of hazards : I II III • General Requirements for PPE: • Design principles (Ergonomics) • Innocuousness (No risks for user) • Comfort and efficiency • Information Supplied Categories Level Minors Intermediate Irreversible/Mortal User Information X X X Technical documentation X X X X Self-Certification CE Type Examination X X Quality Control System X Mark April 12
EN Standards - Gloves EN 420This standard defines the general requirements for glove design and construction, innocuousness, comfort and efficiency, marking and information applicable to all protective gloves. EN 388Protection against mechanical hazards is expressed by a pictogram followed by four numbers (performance levels), each representing test performance against a specific hazard. EN 407 This standard specifies the test methods and the general requirements, the classification and the marking of gloves for protection against heat and/or fire (flames, contact heat, convective heat, radiant heat, small metal splashes or large projections of molten metal). EN 374This standard specifies the capability of gloves to protect the user against chemicals and/or micro-organisms. EN 511 This standard applies to any gloves to protect the hands against convective and contact cold down to –50 °C. April 12
EN 420 • Requirements • Glove Construction and Design • Gloves have to offer the greatest possible degree of protection in the foreseeable conditions of end use • When seams are included, the strength of these seams should not reduce the overall performance of the glove. • Innocuousness • The gloves themselves shouldn’t cause any harm to the user • pH of the glove should be between 3.5 and 9.5 • Chromium (VI) content should be below detection (less than 3 ppm) • Natural rubber gloves shall be tested on extractable proteins as per EN 455-3. Cleaning Instructions If care instructions are provided, the levels of performance should not be reduced after the maximum recommended number of cleaning cycles. April 12
