Slide Show Notes
Hand tools are nonpowered tools that require human force in order to function and include anything from axes to wrenches.
Other common examples of hand tools include screwdrivers, hammers, punches, handsaws, chisels, files, snips, axes, knives, box cutters, wrenches, pry bars, hooks, and pliers
Modify this slide to list the specific types of hand tools used at your facility.
Bring examples of the hand tools used at your workplace.

3. Hand Tool Hazards
The greatest hazards of hand tools result from misuse and improper maintenance.
Examples:
Using a screwdriver as a chisel and the tip breaks
Wooden handle is damaged and the head of the hammer flies off
Wrench, with jaws sprung, slips and your hand strikes another object
Impact tool, such as a chisel, with a mushroomed head shatters into fragments
Slide Show Notes
The greatest hazards posed by hand tools result from misuse and improper maintenance.
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.
A wrench must not be used if its jaws are sprung, because it might slip.
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.

4. Selecting the Right Tool
Consider the shape, size, and grip of the tool
Consider the quality of the tool
Use spark-resistant tools when working near flammable materials
Use insulated tools when working near electricity
Slide Show Notes
Consider the shape and size of the tool and the handle or grip - the tool should be comfortable to hold and should fit your hand properly. Do not select undersized tools
Consider the quality of the tool. Cheaper tools are more likely to break, get damaged, or become dull. Select high-quality tools.
Iron and steel hand tools can generate sparks, which are dangerous around flammable substances. Instead, use spark-resistant tools made from brass, plastic, aluminum, or wood.
Use insulated tools when working around electricity. Select tools that are rated for the voltage you will be working near. Also, do not work on or near energized electrical equipment unless you are properly trained.

5. Consider Tool Ergonomics
Handles with no sharp edges or finger grooves
Handles coated with soft material
Handles with non-slip surfaces
Tools with angle for working with straight wrist
Tools designed to work in either hand
Spring-loaded to return to open position
Slide Show Notes
Ergonomics is an important part of hand tool safety. Hand tool use in the workplace often involves repetitive motion, awkward body positioning, and the use of force—all are indicators of potential ergonomic injury. Select tools that can be used effectively with less force, less repetitive movement, and less awkward positioning of the body.
Select tools with handles that do not have any sharp edges or finger grooves. Finger grooves require you to place your fingers in a specific position on the handle, which may not fit your hand size properly.
Select tools with handles that are coated with a soft material so the force of a hard object is not placing contact pressure on your hand, which could cause ergonomic injury.
Select tools with non-slip handles to maintain a better grip.
Find tools that are angled appropriately to allow you to work with a straight wrist. Straight tools are not always the best option because you are required to put your wrist at an awkward angle in order to get the work done.
Select tools that are designed to work in either hand. You can prevent some of the repetition by switching hands.
Find double-handled tools that are spring-loaded to return to the open position so you do not have to open the tools as well as close them.

6. Carrying Tools Toolbox, belt, or pouch
Never carry sharp tools in your pocket
Hold sharp edges or points away from body
Don’t carry tools in your hand when climbing ladders
Keep tools out of walkways and edges
Hand tools to others, do not throw them
Slide Show Notes
Use a toolbox, toolholder, tool belt, or tool pouch to carry tools in order to protect yourself as well as the tool.
Never carry sharp or pointed tools in your pocket.
Carry sharp or pointed tools with the sharp edge or point away from your body. Just in case you slip or fall, you will not land on the sharp edge of the tool because it faces away from your body.
Do not carry tools in your hand when climbing ladders. Use a belt, rope, or hoist.
Do not lay tools down in a walkway where someone can trip over them or on a high edge where they could fall on someone.
Hand tools to others, do not throw them

7. Maintaining and Repairing Your Tools
Purchase quality tools
Inspect for damaged edges and handles
Keep edges and tips sharp
Replace damaged handles
Report broken or damaged tools
Tag damaged tools “Do Not Use”
Slide Show Notes
Avoid repair and maintenance costs by purchasing the best quality tools. Your tools will last longer and are less likely to be damaged from proper daily use.
Inspect tools for dull or damaged edges, and damaged handles or grips. Wooden handles must be kept free of splinters or cracks and be held tight in the tool.
Have a professional sharpen edges or tips of tools and blades.
Replace damaged handles or grips immediately.
If a tool breaks or malfunctions, report it to your supervisor.
Mark or tag damaged tools with “Do Not Use” in order to prevent a co-worker from using the tool and getting injured.

8. General Tool Safety Practices (CONT’D.)
Wear PPE appropriate for the work
Do not wear loose clothes or jewelry
Do not work with oily or greasy hands
Slide Show Notes
When using hand tools, wear appropriate personal protective equipment (PPE), including safety glasses, work gloves, work boots with steel toes, and tough work clothes.
Keep cutting tools sharp, well lubricated, and in good condition to be sure they work properly.
Never wear loose clothing or jewelry, and tie back long hair when using hand tools.
Mark damaged tools clearly and notify your supervisor.
Do not work with oily or greasy hands because you are likely to lose your grip on the hand tool, which could result in an injury.
Bring examples of PPE (personal protective equipment) used in your workplace when working with hand tools.

9. General Tool Safety Practices (CONT’D.)
Use the right size and type of tool for the job
Do not use tools that are loose or cracked
Do not put tools on edges at heights where they could fall
After using a tool, clean it and put it back in its proper place
Slide Show Notes
Select the correct tool for the job and make sure it is the correct size needed for the job.
Do not use tools that are loose, cracked, or otherwise damaged.
Do not place tools on the edge of tables, work benches, or other flat surfaces. A co-worker could easily walk by that tool and be injured, especially if the tool has a sharp edge or blade.
After using a tool, clean it and put it back in its proper place. Cleaning the tool will help maintain it. Putting the tool back will also make it easier to find it next time you need it.

10. Types of Portable Power Tools
Electric
Pneumatic (air)
Liquid fuel
Hydraulic
Powder-actuated
Regardless of the source of energy, tools present dangers because of their power, speed, and sharp edges. Each of these types of power tools has specific hazards:
Electric
Pneumatic (air)
Liquid fuel
Hydraulic
Powder-actuated

11. Power & HAND Tool Hazards
Hit by flying debris
Hit by broken tool part
Puncture with a sharp tool
Explosion or fire when sparks from a tool ignite flammable or combustible materials
Electric shock from a frayed or defective power cord
Musculoskeletal disorders (MSDs) from repetitive misuse of a tool
It is easy to overlook hazards on hand or power tools, or figure that it is no big deal. You might think, “I’ll just use it this once.” Some common hazards associated with hand and power tools are:
Someone is hit by flying debris from the item on which the tool is used.
Part of tool hits someone after it breaks or shatters under force.
A person punctures themself with a sharp tool.
Sparks from a tool ignite flammable or combustible material.
Someone receives an electrical shock from a frayed or defective power cord or tool.
Repetitive misuse of tools (e.g., awkward grip, excessive grip, awkward position) can lead to musculoskeletal disorders (MSDs).

12. POWER TOOL HAZARDS

13. General Precautions for Operating Power Tools
Never carry a tool or unplug it by the cord or hose
Disconnect tools when they are not in use
Make sure observers are at a safe distance
Secure work with a vise, clamp, or other support
Keep cords and hoses away from heat, liquids, and sharp edges
Examine tools before each use
Power tool hazards and injuries can be avoided by taking several simple precautions:
Do not carry a tool by the cord or yank the plug. It can result in loose wires and create a fire hazard.
Always disconnect tools when they are not in use to prevent accidental start-up.
Make sure no one is standing near you when operating a tool unless they are wearing appropriate protective equipment. Anyone watching the work may be hit by flying debris.
Secure the working surface with a vise, clamp, or other support. Moving work surfaces can cause the tool to “kick back,” injuring the operator.
Always make sure that cords are not strung near a heat source, across sharp edges, or through liquids.
Examine tools before each use for defects or damage.

14. Tool Guards Guards protect from: Point of operation hazards Nip points
Rotating parts
Flying chips or sparks
Tool guards offer protection from:
Point of operation hazards
Nip points
Rotating parts
Flying chips or sparks

15. Pneumatic Tool Safety Always wear eye and hearing protection
Make sure air hose connections are secure
Ensure the safety clip for attachments is installed and secure
Use screens to protect nearby workers
Never point the tool at anyone
When using pneumatic tools:
Always wear eye and hearing protection. Face protection is recommended.
Check air hose connections to make sure they are secured properly.
Make sure a safety clip or retainer is installed to prevent attachments, such as chisels on a chipping hammer, from being unintentionally shot from the barrel.
Screens must be set up to protect nearby workers from being struck by flying fragments around chippers, riveting guns, staplers, or air drills.
Never point a compressed air gun toward anyone. Users should never “dead-end” it against themselves or anyone else.

16. Powder-Actuated Tools
Do not use in an explosive or flammable atmosphere
Inspect the tool prior to use
Never point the tool at anyone
Load the tool only when it is going to be used
Keep hands clear of the barrel end
If you are not familiar with this type of tool, do not use them until you have been properly trained. Remember, although these are not guns, they can cause damage like one!
Don’t use in an explosive or flammable atmosphere.
Inspect the tool prior to use.
Never point the tool at anyone.
Load the tool only when it is going to be used.
Keep hands clear of the barrel end.

17. What’s Wrong with This Picture?
Employee was cutting plywood with a circular saw
This is a simulation of an actual workplace accident. It was inspected and documented by OSHA: Accident , Report ID , Inspection
An employee was preparing to cut through some plywood.
He placed one end of the plywood on the ground, and held up the other end with one hand so that he could operate the circular saw with his other hand.
He taped back the self-retracting lower blade guard that automatically closes over the lower part of the blade when material is not being cut.
As he began cutting, the saw got caught in the wood and kicked backward.
The man was struck in the abdomen with the unguarded circular saw. He was hospitalized with a 10” laceration that required a number of stitches.

18. What’s Wrong with This Picture?
He tapes back the lower blade guard and holds the wood. The saw catches in the wood and kicks back.

19. What’s Wrong with This Picture?
The saw hit the employee in the abdomen, leaving a 10” laceration
What caused the accident? Possible answers:

20. WHAT CAUSED THIS ACCIDENT?
Possible Answers…
The guarding for the saw was disabled. The guard probably got caught in the wood when cutting at a downward angle. He had probably cut wood this way many times before and never been hurt, so he assumed it was safe.
The sheet of plywood was not in a safe position for cutting. To hold the wood still in this upright position, he was probably pushing down, which put too much pressure on the blade and caused the saw to kick back.
Because the employee was not able to use both hands to control the saw, he was not able to control it when it kicked back.
The saw blade may have been dull, which could contribute to the saw catching on the wood.
Possible answers:

21. HOW COULD THIS WORKER HAVE CUT THE BOARD SAFELY?
Possible answers…
When using a circular saw, the material to be cut should have been laid flat on top of sawhorses or a designated cutting table.
In this position, the guard would have move freely out of the way.
He would have been in a better position to control the saw and avoid injury, even if the saw kicked back
He should have inspected the blade prior to use. Blades must be sharp and have no signs of damage.

22. Code of Safe Practices
In California, there is an entire group of safety and health regulations which pertain to construction activities only. These regulations are included in the Construction Safety Orders (“CSOs”).
One element of the CSOs is the Code of Safe Practices, which is part of the company’s Injury and Illness Prevention Program (IIPP).

23. Code of Safe Practices
The employer must adopt and develop a written Code
It must be specific to an employer’s operations
It must be posted or readily available at the job site
Workers must be directed to read and sign it
