SAFETY FOOTWEAR TRAINING

• WHY SAFETY FOOTWEAR?

• CORE COMPONENTS OF A WORK BOOT

• SAFETY FEATURES OF A WORK BOOT

WHY DO WE NEED

SAFETY FOOTWEAR?

-The biggest challenge is the almost constant hard surface we

move on every day; streets and flooring..

-Orthopedic seen it is as bad as it could be; our body and feet

are made for rugged terrain and varied use of muscles, tendons

and joints, says chiropodist.

-Walking on hard surfaces will over time impact us.

Lise Burud Smestad, Chiropodist:

Our foot is one of the body's most advanced parts

Each foot has:

• 26 bones • 33 joints • More than 100 tendons, muscles and different ligaments • The foot contains a quarter of all the bones in our body • Heel bone is the largest of the 26 bones in foot *The foot has 250,000 sweat glands. When they are active, they can produce from 12 to 25 ounces of sweat per day and sometimes more

THE FOOT

Shock Absorption & Potential Injuries

Heel bone Our natural shock absorber in the heel's “fat pad” - The heel is designed to accommodate the largest pressure and therefore has a “fat pad” of about six millimeters. The forefoot has approximately four millimeters fat.

Dangers / Potential Injuries - Prolonged stress leads to adipose tissue cushioning effect

decreases so that the skin will remain closer to the heel bone which cause pain.

- Increased resistance to the movement of the tendons in the arch will give plantar fasciitis which is an inflammation of the ligaments and causes severe heel pain.

- Metatarsalgia common foot disorder that can affect the bones and joints at the ball of the foot.

Boot Flexibility, Boot Stability/Support and Increased Cushioning can help to avoid potential foot injuries and pain

THE FOOT’S PRESSURE POINTS

Lateral ligament injury - Outer ligament injuries

The cause: - Works on uneven surfaces ... - Climb stairs and ladders ....

with footwear that does not give the foot adequate support

and stability in the ankle area.

The Scope: - Can be a simple injury with no or low absenteeism - Can cause fracture of ligaments with long absence

SUPPORT AND STABILITY

Heel Counter Stability: • Stable heel counter • Heel area width

Torsion Stability: • Mid-sole stability • Construction method

WHAT MAKES A RED WING BOOT WATERPROOF

• EN certification

• WRU – Upper material is tested and are

water repellent

• WR – Boot is waterproof tested – needs

a waterproof bootie construction.

1. Upper Material is Water-Resistant or Waterproof (Leather or Non-Leather)

2. Boot is built with 3 layer approach

1. Lining added to help move moisture away from foot

2. Foam added for comfort & protection

3. Waterproof bootie is an additional barrier to keep water out

SATRA TM94:2018 – ‘Breaking force and extension at break of shoelaces’ is used to determine the breaking force and extension at break of shoelaces of all types, in both dry and wet conditions

SATRA TM93:2004 – (ISO 22774:2004) - Abrasion between shoelaces and eyelets is used to determine the breaking force between lace and eyelet. Red Wing test requirement

SHOELACE TESTING SATRA TM94

SATRA TM93

As the shoe lining comes into direct contact with the foot, the

quality of the lining and its properties are very important.

• #1 lining used in a Red Wing Boot Combat Super Knit

• Quick Drying, Moisture Wicking, High Abrasion & Tear Resistance

• Agion also added to some which provides odor control

• Mesh Linings also very common Breathability & Comfort

BOOT MATERIALS – LINING

Common characteristics/features in premium work boot liners: - AntiMicrobial: Odor Control - Moisture wicking: Pulls moisture away from skin, easier to evaporate - Quick Drying: Dries fast when boots are wet or damp from sweat - High abrasion and tear resistance: Critical for Red Wing

- High demand of AR required at RW (50,000 cycles). - EN requirements – Wet (25,600 cycles for heel grip), Wet (12,800 for qtr/vamp)

SAFETY FEATURES

Steel Aluminum

SAFETY TOE CAP: METAL

• Generally strong, thin & economic

• Most traditional material safety toe

• Material thickness positive = good volume

for toes

• Heavy - Known for protection vs light weight

• Retain the cold

• Very strong but with less weight than steel...

~>30% lighter than steel

• Material thickness positive = good volume

for toes

• Great for appearance - lower profile

Fiberglass Carbon fiber / Nano Toe Composite/Plastic/Polymer

SAFETY TOE CAP: NON-METALLIC

• High strength fiberglass + modified

resin - Incredibly strong yet metal free

• Very rigid, high performance

• Consistent quality in all sizes as well

as for all production volumes

• Good material for low or high temps.

• More expensive than other materials

• High strength fiberglass + modified

resin

• Extremely rigid, guarantee high

performance with thinner walls

• Consistent quality in all sizes as well

as for all production volumes

• Good material for low or high temps

• More expensive than other materials.

• Light weight and metal free

• More inexpensive than other

materials

• Less consistent with testing as

other materials

• Good material for low or high

temperatures.

Steel • Excellent protection against fine wire and needles • Stiff - affects resistance when walking • Retain the cold • Affects shock absorption capability

Non-metallic

• Flexible – Does not affect the foots movement • Does not retain the cold • Does not affect the shock absorption ability

EN ISO 20345 – 1100N

270 lbs = 1200n

Rubber

• Best material for achieving best in class slip

• Best slip resistance is achieved with a combination of rubber blends and sole

pattern

• Only material that will achieve heat resistance – HRO level at 300oC

PU

• Organic polymer known for its resilience and compression resistance

• Is much lighter material than rubber

• Has better rebound than rubber

• ShieldLite/ComfortMax is added BASF Hydrolysis plus

SuperSole PU

• Legacy style – iconic platform in RW Brand

• Lightweight single density, flexible

• Re-soleable in Red Wing, Minn

• Best for Oil/Gas

OUTSOLE MATERIALS

ELECTRICAL HAZARD (EH)

Electric shock incidents, commonly

referred to as “shocks,” occur when

a human body physically becomes

a portion of an energized electrical

circuit. This happens when current

flowing through an electrical circuit

flows through a portion of the

human body.

Electrostatic discharge (ESD)

The ESD occurs when

differently-charged objects are

brought close together or when

the dielectric between them

breaks down, often creating a

visible spark which can ignite

in areas with flammable

material or explosives, Or even

damage sensitive electronics.

Antistatic EN – SD ASTM

Petroking ESD CEI EN 61340-5-1:2016/COR1:2017, CEI EN IEC 61340-4-5:2018 CEI EN IEC 61340-4-3:2018

SRA – Ceramic tile with detergent/soap

SRB – Steel with glycerin

SRC – Both

EN ISO 20345:2011 (EN ISO 13287)

• Properties for desired slip resistance are adjusted with the outsole material

in combination with the outsole pattern/Lugs

• One combination can work perfect for one surface, and another terrible on

others

• EN SRC is done to achieve an average good result on different surfaces.

Satra Slip = EN ISO 13287
