ABUSE
The tools workers use every day pose the risk of injury-ranging from banging a thumb with a hammer to serious accidents with power tools. But using the wrong tool or making a simple
mistake can have fatal results. Proper tool use is only one facet of job-site safety, but it is extremely important.
Industry tool designers and manufacturers have improved safety guards, grips and controls, making tools easier and safer to use. Designs continually evolve-tools get lighter and better
balanced-and safety features are one of the most important considerations.
*Provide information required by the OSHA Standards for Hand and Power Tools as found in 29 CFR 1910 Subpart P
Tools Can Be Dangerous
• Tool use is unique to humans
• Manufacturers strive to make tools as safe as possible
• Workers must follow specific precautions
Anthropologists
• Anthropologists would suggest that the use of tools is one of the characteristics that separates us from the rest of the animal kingdom.
• Indeed, tools are such a common part of our lives that it is difficult to remember that they may pose hazards.
• All tools are manufactured with safety in mind but, tragically, a serious accident often occurs before steps are taken to search out and avoid or eliminate tool-related hazards.
• In the process of removing or avoiding the hazards, workers must learn to recognize the hazards associated with the different types of tools and the safety precautions necessary to prevent injuries.
General Safety Precautions
Five basic safety rules:
1. Keep all tools in good condition with regular maintenance.
2. Use the right tool for the job.
3. Examine each tool for damage before use.
4. Operate according to the manufacturer's instructions.
5. Provide and use the proper protective equipment.
The 5 golden rules
• All hazards involved in the use of tools can be prevented by following five basic safety rules:
o Keep all tools in good condition with regular maintenance.
o Use the right tool for the job.
o Examine each tool for damage before use.
o Operate according to the manufacturer's instructions.
o Provide and use the proper protective equipment.
• Employees and employers have a responsibility to work together to establish safe working procedures. If a hazardous situation is encountered, it should be brought to the attention of the proper individual immediately.
• Employees using tools must also be provided with any personal protective equipment necessary to protect them from the hazards of falling, flying, abrasive, and splashing objects, and from harmful dusts, fumes, mists, vapors, or gases.
Hand Tools
• Hand tools are non-powered
• Greatest hazards are misuse and improper maintenance
• Employer must provide safe and proper hand tools
• Employees must use hand tools properly
NON POWERED• Hand tools are non-powered. They include anything from saws to
wrenches.
• The greatest hazards posed by hand tools result from misuse and improper maintenance.
• Some examples would include: Using a screwdriver as a chisel may cause the tip of the screwdriver to break and fly, hitting the user or other employees.
• If a wooden handle on a tool such as a hammer or an axe is loose, splintered, or cracked, the head of the tool may fly off and strike the user or another worker.
• Impact tools such as chisels, wedges, or drift pins are unsafe if they have mushroomed heads. The heads might shatter on impact, sending sharp fragments flying.
• The employer is responsible for the safe condition of tools and equipment used by employees, but the employees have the responsibility for properly using and maintaining tools.
Personal Protective Equipment
• Appropriate personal protective equipment should be worn
• Floors clean and dry
• Tools can be an ignition source
Non Spark RESISTENT
• Appropriate personal protective equipment, such as safety goggles, gloves, etc., should be worn to protect against hazards that may be encountered while using portable power tools and hand tools.
• Safety requires that floors be kept as clean and dry as possible to prevent accidental slips with or around dangerous hand tools.
• Sparks produced by iron and steel hand tools can be a dangerous ignition source around flammable substances.
• Spark-resistant tools made from brass, plastic, aluminum, or wood will eliminate this possible source of ignition.
What Are Spark Resistant Tools
"Non-sparking", "spark-resistant" or "spark-proof" tools are names given to
tools made of metals such as brass, bronze, Monel metal (copper-nickel alloy), copper-aluminum alloys (aluminum bronze), copper-beryllium alloys (beryllium bronze), and titanium.
Preferred "non-sparking" metals have less tensile strength than steels usually used to make tools. A lower tensile strength means the metal has less strength or resistance to tearing apart when stretched under test conditions.
It also means that these tools are softer, wear down more quickly than ordinary steel tools, and have to be dressed more frequently.
Some Non-Sparking Tools
Company Basic Hand Tool Safety Rules1 Use tools that are the right type and right size for the
job.
2 Always inspect tools before use. Remove any damaged or worn tools from service.
3 Never place tools where they hang over the edge of a bench.
4 Use non-sparking tools when there is a possibility of flammable vapors or dust.
5 Use electrically insulated tools when working around electrical components.
6 After using a tool, clean it and return it to its proper storage space.
Personal Protective Equipment
Always wear proper personal protective equipment when using hand tools. This includes:
Safety glasses with side shields
Standard leather work gloves
Cut resistant gloves when working with sharp edges
Closed-toe shoes
Proper Work Practices• Wrenches
– Use metric wrenches for metric bolts and American wrenches for inch bolts.
– Do not over torque a nut or bolt.– Pull rather than push on a wrench.
• Pliers– Do not substitute pliers for a wrench
when turning nuts or bolts.– Cut wire only with pliers designed for
that purpose.– Be sure the pliers jaws can grasp
properly.
Proper Work Practices• Hammers
– Use a hammer of proper weight and size for the task.
– Do not strike a surface at an angle. – Do not use if the handle is loose or
damaged.
• Screw Drivers– Do not use as a pry bar, chisel, or punch.– Prevent slips. Ensure the tip properly fits the
screw slot and don’t force screws.– Use both hands. One to guide the tip and
the other to turn the handle.
Proper Work Practices• Saws
– All work being cut should be secured to prevent movement.
– Keep hands and fingers away from the blade.
– Protect the saw blade when not in use
• Utility Knives– Always cut away from your fingers and
body.– When carrying, always keep the blade
pointed down towards the floor.– Cover or retract the blade when not in use.
Power Tool Classifications
Power tools classified by power source:
• Electric
• Pneumatic
• Fuel-powered
• Hydraulic
Hazards of power tools are related to their power source
Classification
• Power tools are classified by their power source, which include:
o Electric o Pneumatic o Fuel-powered, and o Hydraulic
• Employees must be trained in the use of all tools - including power tools.
• They should understand the potential hazards as well as the safety precautions to prevent those hazards from occurring.
• Power tools can be dangerous when improperly used.
• The power source of a tool will give some clues as to the safety precautions required.
• Let’s review each type of power tool.
Power Tool Precautions
• Never carry by cord or hose
• Never yank the cord or hose
• Avoid heat, oil, and sharp edges
• Disconnect tools when not in use
• Keep others at a safe distance
• Secure work with clamps or vise
• Avoid accidental starting
• Tools should be maintained with care
• Maintain good footing and balance
• The proper apparel should be worn
Safety Devices
• Safety switches and guards are used to prevent injury during tool usage
• It is important that the operating controls on all handheld power tools be located to minimize the possibility of accidental operation
Safety switches are designed to prevent injury by turning the tool off when not in use:
• Constant pressure switch
• Some tools may have a lock-on control provided it can be turned off by a single motion
Guards
Guards should be provided, as necessary, to protect the operator and others from the:
• Point of operation
• In-running nip points
• Rotating parts
• Flying chips and sparks
Never remove guards!
Always THINK moving PARTWHICH COME MEAN
REMOVING YOUR PARTS• The hazardous moving parts of a power tool must be safeguarded.
• Guards should be provided, as necessary, to protect the operator and others from the:
o Point of operation
o In-running nip points
o Rotating parts
o Flying chips and sparks
• Safety guards must never be removed For example, portable circular saws must be equipped with guards. An upper guard must cover the entire saw blade. A retractable lower guard must cover the teeth of the saw, except when it makes contact with the work material. The lower guard must automatically return to the covered position when the tool is withdrawn from the work.
Electric Tools
Several dangers:
• Electrocution
• Burns
• Slight shock
• Falls
Tools must be grounded or double-insulated
Double-Insulated Tools• Hand-held tools manufactured with non-metallic cases are called double-insulated
• Often used in damp locations
• Always disconnect tools from power source
• Hand-held tools manufactured with non-metallic cases are called double-insulated. If approved, they do not require grounding under the National Electrical Code. Although this design method reduces the risk of grounding deficiencies, a shock hazard can still exist.
• Such tools are often used in areas where there is considerable moisture or wetness. Although the user is insulated from the electrical wiring components, water can still enter the tool's housing. Ordinary water is a conductor of electricity. If water contacts the energized parts inside the housing, it provides a path to the outside, bypassing the double insulation. When a person holding a hand tool under these conditions contacts another conductive surface, an electric shock occurs.
• If a power tool, even when double-insulated, is dropped into water, the employee should resist the initial human response to grab for the equipment without first disconnecting the power source.
Extension Cords and Electrical Concerns
• Cords suffer wear and tear
• Exposed wires can be hazardous
• A GFCI should be used
Electric Tool Safety
General safety practices for using electric
tools:
• Electric tools should be operated within
their design limitations
• Gloves and safety footwear are
recommended during use of electric
tools
• When not in use, tools should be stored
in a dry place
• Electric tools should not be used in
damp or wet locations
• Work areas should be well lighted
Powered Abrasive Wheel Tools
• Flying fragments
Inspection of abrasive wheel:
• “Sound test”
• Spindle nut tight, but not distorted
Powered Abrasive Wheel Tool Safety
• Never stand in front during start-up
• Safety guards
When using a powered grinder:
• Always use eye protection
• Always turn off the power when not in
use
• Never clamp a hand-held grinder in a
vise
Pneumatic Tools
• Tools powered by compressed air and include
chippers, drills, hammers, and sanders
• Main danger is getting hit by one of the tool's
attachments or by a fastener the worker is using
with the tool
• Personal protective equipment
• Hose connections
• Safety clip
Fuel-Powered Tools
Hazards of fuel-powered tools:
• Flammable fuels
• Generated heat
Should be operated only by trained employees
• Fuel powered tools can be dangerous due to the flammable fuels used and heat that is generated.
• Most fuels present an ignition source that could lead to fire if not managed correctly.
• In addition, employees must always be cognizant of hot areas on the equipment such as mufflers or engine
parts.
• Failure to recognize these areas can lead to burns or other injuries.
• In light of these facts, always remember that fuel powered tools should be operated only by trained
employees.
Hydraulic Tools
• Operated or effected by the action of water or other
fluid of low viscosity
• Fluid must be an approved fire-resistant fluid
Recommended safe operating pressure must not
be exceeded for:
• Hoses
• Valves
• Pipes
• Filters
• Fittings
Your Responsibilities
All hazards involved in the use of hand and
power tools can be prevented by following
five basic safety rules:
1. Keep all tools in good condition with
regular maintenance.
2. Use the right tool for the job.
3. Examine each tool for damage before
use.
4. Operate according to the manufacturer's
instructions.
5. Provide and use the proper protective
equipment.
Injuries• In the event you are cut:
– Stop the bleeding- Use gentle pressure
– Clean the wound- Rinse with clean water
– Cover the wound- Bandage or gauze
• Seek medical attention immediately through Health Services and Call site safety immediately.
