19. Tools and Techniques
HAND TOOLS
Injuries with hand tools are not often serious but
they do involve lost time.
Common causes include:
using the wrong tool,
using the right tool improperly,
haste,
and lack of training or experience.
20. Tools and Techniques
POWER TOOLS — DRILLS
Safety Basics:
• Make sure that electric tools are properly
grounded or double-insulated.
• Never remove or tamper with safety devices.
• Study the manufacturer's instructions before
operating any new or unfamiliar electric tool.
• Before making adjustments or changing
attachments, always disconnect the tool from the
power source.
21. Tools and Techniques
POWER TOOLS — DRILLS
Safety Basics:
• When operating electric tools, always wear eye
protection.
• When operating tools in confined spaces or for
prolonged periods, wear hearing protection.
• Make sure that the tool is held firmly and the
material properly secured before turning on the
tool.
22. Tools and Techniques
POWER TOOLS — SAWS
Basic Saw Safety:
• Wear protective clothing and equipment. Eye
protection is essential.
• Where saws are used in confined spaces or for
prolonged periods, wear hearing protection.
• Where ventilation is inadequate, wear a dust
mask for protection against dust. Over time,
exposure to dust from particle board and other
materials may cause respiratory problems.
23. Tools and Techniques
POWER TOOLS — SAWS
Basic Saw Safety:
• With electric saws operated outdoors or in wet
locations, you must use a ground fault circuit
interrupter.
• Never wear loose clothing, neck chains,
scarves, or anything else that can get caught in
the saw.
• Leave safety devices in place and intact on the
saw. Never remove, modify, or defeat guards.
Keep your free hand away from blade.
24. Tools and Techniques
POWER TOOLS — AIR
Air-powered tools include jackhammers, chipping
hammers, drills, grinders, ... etc.
Safety Basics:
• Run combustion engines outside to prevent the build-
up of carbon monoxide gas.
• Occasionally workers suffer eye injuries when
compressed air is used to blow out formwork. Wear
safety goggles and respiratory protection.
25. Tools and Techniques
POWER TOOLS — AIR
Safety Basics:
• Always secure hose connections with wire or safety
clips to prevent the hose from whipping except when
automatic cut-off couplers are used.
• Make sure hoses are clear of traffic and pose no
tripping hazards.
• Replace worn-out absorption pads and springs.
• Some tools have a high decibel rating – for instance,
jack hammers and impact drills. To prevent hearing
loss, always wear hearing protection.
26. Tools and Techniques
POWER TOOLS — AIR
Safety Basics:
• Never tamper with safety devices.
• Never use air to blow dust or dirt out of work clothes.
Compressed air can enter the skin and bloodstream
with deadly results.
• Turn off the pressure to hoses when the system is
not in use.
• Turn off the air pressure when changing pneumatic
tools or attachments.
27. Tools and Techniques
WELDING AND CUTTING
Safety Basics:
• Obtain a hot work permit through the safety officer if
required.
• Keep welding area free of flammable and explosive
material.
• Provide fire barriers such as metal sheets or fire
blankets and fill cracks or crevices in floors to prevent
sparks and slag from passing through.
28. Tools and Techniques
WELDING AND CUTTING
Safety Basics:
• Provide fire extinguishers suitable for potential types
of fire. Know where the extinguishers are and how to
use them.
• Provide a firewatch where necessary — a worker to
watch for fires as the welder works and for at least
thirty minutes afterward. The person must be fully
trained in the location of fire alarms and the use of fire-
fighting equipment. Some situations may require more
than one firewatch.
29. ACCIDENTS IMPACT
Examples
1. Time lost from work by injured employee.
2. Lost time by fellow employees.
3. Loss of efficiency due to break-up of crew.
4. Lost time by supervisor.
5. Training costs for new/replacement workers.
6. Damage to tools and equipment.

9. Damage from accident: fire, water, chemical,
explosives, etc.
10. Failure to fill orders/meet deadlines.
11. Overhead costs while work was disrupted.
12. Other miscellaneous costs
13. Others?
31. CASE STUDY
MILLER PARK STADIUM
July 1999 crane collapse
caused the deaths of 3
construction workers.
32. CASE STUDY
ACCEDENT RESULTS
- Delayed the opening for One Year
- 100 Million in repairs.
- Three construction workers killed, several others
injured
- On Dec. 1, 2000, a Milwaukee County jury awarded
$94 million in punitive damages and $5.25 million in
compensatory damages to the families of three
ironworkers killed in the accident. Although the families
have been paid $27 million for their loss, the issue of
the large punitive damage award is under appeal.
