Have you ever considered….

• The comfort and protection of the
• perator 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?

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:

Control of Concrete & Masonry Dust in Construction – CalOsha

20 www.hilti.com Dust 2009

Cal OSHA

Goal is to control employee exposure to airborne particulate during

• perations in which powered tools or equipment are used to cut, grind,

core or drill concrete or masonry materials.

21 www.hilti.com 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.

22 www.hilti.com 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.

24 www.hilti.com Dust 2009

Exemptions

Plastering operations Powder-actuated tool work Downward drilling Work incidental to the installation of concrete work Wall Siding

25 www.hilti.com Dust 2009

26 www.hilti.com 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

27 www.hilti.com 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

28 www.hilti.com 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

29 www.hilti.com 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!

32 www.hilti.com Dust 2009

• 1. Hilti Consumables
• air turbulence and air flow are

defined exactly by the special shape and design of the tool

• built-in DRS air channels extract the

dust right at its source

• for best-possible dust removal

performance

• 2. Hilti Power Tool Design
• advanced ergonomic design captures

dust the moment it is generated

• optimized air-flow inside the

tool’s built-in dust removal hood

• the dust removal efficiency extends life
• f cutting discs, improves cutting

performance

• 3. Hilti Accessories
• extremely robust and durable
• keyless quick-release mounting

system

• dual-chamber dynamic air-flow

system

• compact and very convenient
• 4. Hilti Vacuum Cleaners
• combination of a small, mobile

and robust vacuum cleaner with continuous high suction performance

• new filter technology briefly reverses the

flow of air inside the system and thus blasts the filter clean every 15”

Hilti Dust Removal Systems

Four components – one winner

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 the vacuum removal system.

1 Life-expectancy test with a Hilti DCH 230 cutter: The dust

resistance of the carbon brushes was tested in a dust chamber. Without Hilti DRS, the carbon brushes had to be changed for the first time after approx. 85 hours. In comparison, in dustless conditions, the same power tool ran for approx. 140 hours in the same test chamber before the brushes needed changing for the first time. Please note: Tests conducted on a test rig are not always directly comparable with real-life conditions. Results may differ based on operator technique, specific application and tool combination.
