Key Learnings Why Alfred is neededWhat the Alfred range isWho the markets for Alfred areWhat the certificates are that Alfred hasLaunch
Hazard Location Importance Electronics or mechanical machinery put in this area can spark orheat up. This leads to the atmosphere around the equipmentigniting causing an explosion. These explosions have previously caused: Expensive damagesDelayed productionInjuriesFatalitiesLost customersFines However, even without an explosion putting equipment in thisarea that is not certified can lead to fines and jail time.
What is a hazardous location or explosive atmosphere? Gas explosions Dust explosion Flyings and fibres
What is a hazardous location or explosive atmosphere?Hazard LevelContinuous hazardIntermediate hazardUnusual e atmosphere occurs continuously or frequently during normal operationExplosive atmosphere is likely to occur occasionally during normal operationExplosive atmosphere is not likely to occur during normal operation
Purpose of AlfredAllow a company with a hazardous environment to still maintainmachinery safety.
Fortress’ Alfred Logo: Fortress Interlocks Range name: Fortress’ Alfred or Alfred Range descriptor: Volatile environment interlocking solutions Inspiration: Alfred Nobel Part number prefix (3 letters): EXPHighly volatile environments can and have caused huge industrial accidents.Our Alfred range is designed to be "spark-less" to keep operators safe frommachinery and the risk of explosion with a range of options: Explosion Proof Interlock - offers a safety guard locking solution to allowfast and safe access to a machine with a rundown time. Stainless trapped key range - ideal for more complex sequencing anddesigned for machinery not controlled by a PLC.Fortress’ Alfred

Target Market - Food and Beverage (including agriculture)Sugar, Grain, Flour, Coffeepowder, Cocoa powder arejust a few examples ofCombustible Dust in Foodand BeverageDistilleries are example ofFlammable Gas Food andBeverage
Target Market – Wood manufacturingWood dust can bevery combustibleIn the last 3 yearsthere have been over60 explosions!
Target Markets – Chemical and pharmaceuticalsIn the chemical andpharmaceutical industry there isthe presence of a large areawith a potentially explosiveatmosphere caused bycombustible dust and gas.
Target Markets – Waste Process IndustryOutgassing of effluentsfrom large areas of awastewater plantproduces explosive gases
Target Markets – ManufacturingFrom spray paint booths to metalwork, many areas ofmanufacturing produce explosiveatmospheres.
Other Large MarketsOil and Gas – This is the mostwell-known industry withHAZLOC areasOpen Cast Mining – Whilstunderground mining is notpossible with Alfred open castmining is a large market and isa place Alfred can be used

ATEX – Europe“ATEX” comes from the French title of the 94/9/EC directive:Appareils destinés à être utilisés en ATmosphères Explosibles Directive 2014/34/EU (formerly known as94/9/EC) - The ATEX Equipment Directive- refersto the equipment and protective systemsintended for use in explosive atmospheres. Directive 99/92/EC – The ATEX WorkplaceDirective - refers to minimum requirements forimproving the health and safety protection ofworkers at risk from explosive atmospheres.

How does a customer know what they need?1. Find the certificate that applies in the location of the enduser2. Do a risk assessment3. If the interlock is being added to something already rated,the interlock needs to be at least the existing rating4. If a customer needs something of a lower rating, they canuse Alfred5. If the customer is looking to put the interlock in a higherrated area, consider discussing moving where the interlockgoes

Fortress met with deck builders, and it quickly became clear the market needs a steel system that is affordable, looks and assembles like wood, and is easy to install. To answer these requests, we introduced Evolution by Fortress Framing, a steel system designed by deck builders, for deck builders. 1 Our Story 3 Wood to Steel 4 Why Evolution?

The coronavirus pandemic is having a devastating impact around the world. In the UK, people affected by dementia have been hardest hit and our fragmented social care system has been exposed for all to see. Alzheimer’s Society is the UK’s leading dementia charity, and in this report we bring together evidence from a wide range of sources to shine a light on the impact of coronavirus disease .
