Tool Safety

Subpart I “Tools”

Hand and Power1926.300 to 307

Operating Engineers National Hazmat Program

4

Introduction

A tool is an object used to perform work.

Tools injure or kill thousands of workers each

year.

The tools being referred to are:

Hand tools Power tools

Abrasive tools Woodworking tools

Jacks Air receivers

Mechanical power transmission apparatus


5

IntroductionThis is largely due to lack of proper

guarding in areas such as:

Rotating or moving parts

Over grinding wheels

When the tool is designed

to have them


6

Introduction

Many injuries happen because tools were

modified, defective, or used improperly.


7

Introduction

It is very hard to work

without tools.

This presentation of

“Tool Safety” will help

you to recognize hazards

and minimize

potential accidents.


8

1926.300General Requirements

All hand and power tools and similar equipment,

whether furnished by the employer or the

employee, shall be maintained in a safe condition.

They should be inspected for any defects.

Operating and maintenance instructions should

be made available and read by the operator.


9


When power operated tools are designed to

accommodate guards, they shall be equipped

with such guards when in use.

Point of operation Ingoing nip points

Rotating parts Flying chips and sparks


10


Guards are necessary when using tools in order to :

Keep particles from flying at you

Prevent contact with sharp edges

such as saw blades

Keep you and your clothing

from getting caught in the tool


11


The following are some of the machines which

usually require point of operation guarding:

Guillotine cutters Shears

Alligator Shears Power presses

Milling machines Power saws

Jointers Portable power tools

Forming rolls and calenders


12


PPE--Employees using hand and power tools

and exposed to the hazard of falling, flying,

abrasive, and splashing objects shall be provided

with the particular PPE necessary to protect them

from the hazard.


13


PPE--Employees using hand

and power tools and exposed to

harmful dusts, fumes, mists,

vapors, or gases shall be

provided with the particular

PPE necessary to protect

them from the hazard.


14

1926.301Hand tools

Employers shall not issue or permit the use of

unsafe hand tools.

Wrenches, including adjustable, pipe,

end, and socket wrenches shall not be

used when jaws are sprung ( wider

or less stable than designed) to the

point that slippage occurs.


15

1926.301Hand tools

Impact tools, such as drift pins,

wedges, and chisels, shall be

kept free of mushroomed

heads (being soft and

expanded from being

struck).


16

1926.301Hand tools

The wooden handles of tools

shall be kept free of splinters

or cracks and shall be kept

tight in the tool.


17

1926.302Power-operated hand tools

When speaking of power tools, electrical tools

are the most commonly used.

Drills Grinders

Saws Nailers

Chain Saws Jacks


18


Electrical hand tools should follow these basic

safety procedures:

Tools are to be double-

insulated and grounded

Do not use in damp or

wet conditions

Do not use kinked, frayed, or broken cords


19


Other sources of power for hand tools would

include pneumatic, powder-actuated, fuel, and

hydraulic fluid.


20


Pneumatic tools use

compressed air power for

operation. These tools are

very dangerous due to the

pressurized air. Even at

very low pressures,

compressed air can cause

injury.


21


Pneumatic tools should follow these basic rules:

Never exceed safe operating pressures

Never point them at others

Never look into them

Use safety clips or retainers

Never reduce pressure to below 30 psi


22


Pneumatic tools should follow these basic rules:

Never use

compressed

air to clean

work areas


23


Fuel powered tools are not to be

operating while being refueled,

serviced, or maintained.

The fuel shall be transported,

handled, and stored accordingly

to OSHA’s Subpart F.


24

When fuel powered tools are being used in

enclosed spaces, the concentration of toxic

gases must be assessed and the proper PPE is

to be used.



25


Hydraulic power tools operate by fluid under

pressure. This fluid is to be fire resistant and

retain its operating characteristics at the most

extreme temperatures to which it will be exposed.

The manufacturer’s safe operation pressures for

hoses, valves, pipes, filters, and other fittings shall

not be exceeded.


26


Powder-actuated tools are to be operated only by

employees who have been trained in the operation

of the particular tool in use.

These tools are to be tested

every day before loading to

see that safety devices are

in proper working condition.


27


Powder-actuated tools operate like guns. They

are not to be loaded until just prior to the intended

firing time and are never to be aimed at anyone.

All tools should be used with the correct shield,

guard, or attachment recommended by the

manufacturer.


28

1926.303Abrasive wheels and tools

When dealing with abrasive wheels and tools

(usually saws and grinders) they must be supplied

with sufficient power to maintain the spindle

speed at safe levels under all conditions.

Do not run a wheel or blade faster than its

maximum rated capacity.


29


Appropriate guarding must be used on tools,

covering the spindle end, nut, and flange

projections unless otherwise protected.

The safety guard is to be

mounted so as to maintain

proper alignment with the

wheel.


30


All abrasive wheels are to be closely inspected

and ring-tested before mounting.

A ring test is a way of making sure an abrasive

wheel is free of cracks and other effects. Upon

tapping, undamaged wheel rings will sound

clear, while damaged will sound flat.


31


Protective eyewear is to be worn at all times

when working with these tools except where

adequate eye protection is

afforded by eye shields

which are permanently

attached to the bench

or floor stand.


32

1926.304Woodworking tools

Woodworking tools would include circular saws,

radial arm saws, crosscut saws, and ripsaws.

This equipment shall be provided with a

disconnect switch that can either be locked or

tagged in the off position.


33

1926.304Woodworking tools

Circular saws are to have the operating speed

permanently marked on all circular saws over 20

inches in diameter or operating at over 10,000

peripheral feet per minute.

These tools must also be

properly guarded with

hoods and covers.


34

1926.305 JacksTypes of jacks we may be referring to would be

lever and ratchet, screw, and hydraulic.

The manufacturers rated

capacity shall be legibly

marked on all jacks and

shall not be exceeded.

All jacks are to have a positive stop to prevent

overtravel.


35

1926.305 Jacks

Jacks are to be centered under the load on a firm

and level foundation.

Jacks being used on a constant basis should be

inspected every 6 months. Those jacks subjected

to an abnormal load or shock shall be inspected

immediately before and after.


36

1926.306 Air receivers

This area concerns compressed air receivers, and

other equipment used for cleaning, drilling,

hoisting, and chipping.

Air receivers are storage tanks for compressed air.

They must be installed above ground so that all

drains, handholes, and manholes are easily

accessible.


37

1926.306 Air receivers

A drain pipe and valve shall be installed at the

lowest point of every air receiver and should be

cleaned often.

An indicating pressure gage is to be readily

visible. There should also be at least one or more

spring-loaded safety valve.


38

1926.307 Mechanical power transmission apparatus.

This section covers all types

and shapes of power-

transmission belts, rods,

shafts, pulleys, gears, and

similar devices when

operating at 250 feet per

minute or less.


39


This apparatus has dangerous moving parts which

must be guarded:

Belts

Gears

Shafts


40


This apparatus has dangerous moving parts which

must be guarded:

Pulleys Drums

Sprockets Fly wheels

Spindles Chains
