Have you ever considered…. Up to 2.20 lbs of dust are produced with five minutes sawing / cutting. Now imagine working like this for one hour. Or a full day. Consider:  The comfort and protection of the operator and adjacent personnel?  Regulatory compliance and Risk?  How does this impact the life of the tool and consumables?  The drilling/cutting speed of the tools?  Jobsite preparation and cleaning – productivity?  The environment? www.hilti.com 11 Dust 2009

Control of Concrete & Masonry Dust in Construction – CalOsha www.hilti.com 19 Dust 2009

Cal OSHA Goal is to control employee exposure to airborne particulate during operations in which powered tools or equipment are used to cut, grind, core or drill concrete or masonry materials. www.hilti.com 20 Dust 2009

Cal/OSHA Requirements During operations in which powered tools or equipment are used to cut, grind, core, or drill concrete or masonry materials , a dust reduction system shall be applied to effectively reduce airborne particulate. Local exhaust ventilation systems must be used in accordance with manufacturer recommendations. Dust reduction systems must be maintained and effective. www.hilti.com 21 Dust 2009

Cal/OSHA Requirements - Definitions Dust containment device – a device attached to a power tool such as a pouch, bag, plastic container, or similar attachment which is intended to capture dust generated by the tool. Dust reduction system – technology that utilizes the application of water or local exhaust ventilation to reduce airborne dust generated by the use of powered tools or equipment. Local exhaust ventilation may include vacuum systems, dust collection systems, and dust exhaust systems. www.hilti.com 22 Dust 2009

Exemptions Plastering operations Powder-actuated tool work Downward drilling Work incidental to the installation of concrete work Wall Siding www.hilti.com 24 Dust 2009

www.hilti.com 25 Dust 2009

Cal/OSHA Requirements Employee Training – all employees covered by this standard must be trained at least annually in the following topics: • Potential Health Hazards • Methods used by the employer to control exposure of dust • Use and maintenance of dust reduction systems • Personal hygiene www.hilti.com 26 Dust 2009

Cal/OSHA Requirements Supervisor Training – must be trained initially on tasks that lead employees to exposure and procedures for reducing employee risk. Training must be refreshed at least annually. Training must be documented www.hilti.com 27 Dust 2009

Respirator Requirements A respirator should be worn when exposed to silica dust (in addition to engineering controls). Respirator use requires compliance with OSHA Regulations • Current medical evaluation – annually • Current fit test • Training www.hilti.com 28 Dust 2009

Health Risks Exposure to harmful dust may lead to: Silicosis • Lung cancer – Crystalline silica is a carcinogen. Over exposure to silica dust may cause lung cancer. • Chronic Obstructive Lung Disease (COPD) – Over exposure to silica dust may cause COPD. • Decreased lung function – Over exposure to silica may cause scarring of the lungs and decreased lung function. All of these are 100% preventable! www.hilti.com 29 Dust 2009

All system components, including power tools, drill bits, discs, blades or other accessories as well as fully integrated systems, are perfectly matched to maximize the amount of dust removed at its source and collected efficiently by Hilti Dust Removal Systems the vacuum removal system. Four components – one winner 1. Hilti Consumables 2. Hilti Power Tool Design - air turbulence and air flow are - advanced ergonomic design captures defined exactly by the special shape dust the moment it is generated and design of the tool - optimized air-flow inside the tool’s built -in dust removal hood - built-in DRS air channels extract the dust right at its source - the dust removal efficiency extends life - for best-possible dust removal of cutting discs, improves cutting performance performance 3. Hilti Accessories 4. Hilti Vacuum Cleaners - extremely robust and durable - combination of a small, mobile - keyless quick-release mounting and robust vacuum cleaner with system continuous high suction performance - dual-chamber dynamic air-flow - new filter technology briefly reverses the system flow of air inside the system and thus blasts the filter clean every 15” - compact and very convenient www.hilti.com 32 Dust 2009
