General Safety Guidelines
  • Where Mechanical Hazards Occur
  • Hazardous Mechanical Motions and Actions
  • Requirements for Safeguards
  • Non-Mechanical Hazards
  • Controlling Work Shop Risks
  • Safe Work Shop Practices

48
General Safety Guidelines
  • Where Mechanical Hazards Occur
  • The Point of Operation
  • Power Transmission Apparatus
  • Other Moving Parts

49
GSG Where Mechanical Hazards Occur
  • The Point of Operation
  • that point where work is performed on the
    material, such as cutting, shaping, boring, or
    forming of stock.

50
GSG Where Mechanical Hazards Occur
  • Power Transmission Apparatus
  • all components of the mechanical system which
    transmit energy to the part of the machine
    performing the work. These components include
    flywheels, pulleys, belts, connecting rods,
    couplings, cams, spindles, chains, cranks, and
    gears.

51
GSG Where Mechanical Hazards Occur
  • Other Moving Parts
  • all parts of the machine which move while the
    machine is working. These can include
    reciprocating, rotating, and transverse moving
    parts, as well as feed mechanisms and auxiliary
    parts of the machine.

52
General Safety Guidelines
  • Hazardous Mechanical Motions and Actions
  • A wide variety of mechanical motions and actions
    may present hazards to the worker
  • These can include the movement of rotating
    members, reciprocating arms, moving belts,
    meshing gears, cutting teeth, and any parts that
    impact or shear

53
GSG Hazardous Mechanical Motions/Actions
  • These different types of hazardous mechanical
    motions and actions are basic to nearly all
    machines, and recognizing them is the first step
    toward protecting workers from the danger they
    present
  • The basic types of hazardous mechanical motions
    and actions are

54
GSG Hazardous Mechanical Motions/Actions
  • Motions
  • rotating, reciprocating transverse
  • Actions
  • cutting, punching, shearing, bending

55
GSG Hazardous Mechanical Motions/Actions
  • Motions
  • Rotating motion can be dangerous even smooth,
    slowly rotating shafts can grip clothing, and
    through mere skin contact force an arm or hand
    into a dangerous position. Injuries due to
    contact with rotating parts can be severe.

56
GSG HMM/A - Motions
  • Collars, couplings, cams, clutches, flywheels,
    shaft ends, spindles, and horizontal or vertical
    shafting are some examples of common rotating
    mechanisms which may be hazardous. The danger
    increases when bolts, nicks, abrasions, and
    projecting keys or set screws are exposed on
    rotating parts, as shown in the next slide

57

58
GSG HMM/A - Motions
  • In-running nip point hazards are caused by the
    rotating parts on machinery
  • There are three main types of in-running nips.
  • Between parts that rotate in opposite directions
  • Between rotating and tangentially moving parts
  • Between rotating and fixed parts

59
GSG HMM/A - Motions
  • Between parts that rotate in opposite directions
  • Parts can rotate in opposite directions while
    their axes are parallel to each other.
  • These parts may be in contact (producing a nip
    point) or in close proximity to each other.
  • In the latter case the stock fed between the
    rolls produces the nip points.
  • This danger is common on machinery with
    intermeshing gears, rolling mills, and calendars.

60
(No Transcript)
61
GSG HMM/A - Motions
  • Between rotating and tangentially moving parts
  • Some examples would be the point of contact
    between a power transmission belt and its pulley,
    a chain and a sprocket, or a rack and pinion.

62
(No Transcript)
63
GSG HMM/A - Motions
  • Between rotating and fixed parts
  • Nip points can occur between rotating and fixed
    parts which create a shearing, crushing, or
    abrading action.
  • Examples are spoked handwheels or flywheels,
    screw conveyors, or the periphery of an abrasive
    wheel and an incorrectly adjusted work rest.

64
(No Transcript)
65
GSG HMM/A - Motions
  • Reciprocating motions may be hazardous because,
    during the back-and- forth or up-and-down motion,
    a worker may be struck by or caught between a
    moving and a stationary part.

66
(No Transcript)
67
GSG HMM/A - Motions
  • Transverse motion (movement in a straight,
    continuous line) creates a hazard because a
    worker may be struck or caught in a pinch or
    shear point by the moving part.

68
(No Transcript)
69
GSG HMM/A - Actions
  • Actions
  • Cutting action involves rotating, reciprocating,
    or transverse motion
  • The danger of cutting action exists at the point
    of operation where finger, head, and arm injuries
    can occur and where flying chips or scrap
    material can strike the eyes or face
  • Such hazards are present at the point of
    operation in cutting wood, metal, or other
    materials

70
GSG HMM/A - Actions
  • Typical examples of mechanisms involving cutting
    hazards include band-saws, circular saws, boring
    or drilling machines, turning machines (lathes),
    or milling machines.

71
(No Transcript)
72
GSG HMM/A - Actions
  • Punching action results when power is applied to
    a slide (ram) for the purpose of blanking,
    drawing, or stamping metal or other materials.
    The danger of this type of action occurs at the
    point of operation where stock is inserted, held,
    and withdrawn by hand.
  • Typical machinery used for punching operations
    are power presses and iron workers.

73
(No Transcript)
74
GSG HMM/A - Actions
  • Shearing action involves applying power to a
    slide or knife in order to trim or shear metal or
    other materials. A hazard occurs at the point of
    operation where stock is actually inserted, held,
    and withdrawn.
  • Typical examples of machinery used for shearing
    operations are mechanically, hydraulically, or
    pneumatically powered shears.

75
(No Transcript)
76
GSG HMM/A - Actions
  • Bending action results when power is applied to a
    slide in order to draw or stamp metal or other
    materials, and a hazard occurs at the point of
    operation where stock is inserted, held, and
    withdrawn.
  • Equipment that uses bending action includes power
    presses, press brakes, and tubing benders.

78
General Safety Guidelines
  • Requirements for Safeguards
  • Safeguards must meet these minimum general
    requirements
  • Prevent contact
  • Secure
  • Protect from falling objects
  • Create no new hazards
  • Create no interference
  • Allow safe lubrication

79
GSG Requirements for Safeguards
  • Prevent Contact
  • The safeguard must prevent hands, arms, or any
    other part of a worker's body from making contact
    with dangerous moving parts. A good safeguarding
    system eliminates the possibility of the operator
    or another worker placing their hands near
    hazardous moving parts.

80
GSG Requirements for Safeguards
  • Secure
  • Workers should not be able to easily remove or
    tamper with the safeguard, because a safeguard
    that can easily be made ineffective is no
    safeguard at all. Guards and safety devices
    should be made of durable material that will
    withstand the conditions of normal use. They must
    be firmly secured to the machine.

81
GSG Requirements for Safeguards
  • Protect From Falling Objects
  • The safeguard should ensure that no objects can
    fall into moving parts. A small tool which is
    dropped into a cycling machine could easily
    become a projectile that could strike and injure
    someone.

82
GSG Requirements for Safeguards
  • Create No New Hazards
  • A safeguard defeats its own purpose if it creates
    a hazard of its own such as a shear point, a
    jagged edge, or an unfinished surface which can
    cause a laceration. The edges of guards, for
    instance, should be rolled or bolted in such a
    why that they eliminate sharp edges.

83
GSG Requirements for Safeguards
  • Create No Interference
  • Any safeguard which impedes a worker from
    performing the job quickly and comfortably might
    soon be overridden or disregarded. Proper
    safeguarding can actually enhance efficiency
    since it can relieve the worker's apprehensions
    about injury.

84
GSG Requirements for Safeguards
  • Allow Safe Lubrication
  • If possible, one should be able to lubricate the
    machine without removing the safeguards. Locating
    oil reservoirs outside the guard, with a line
    leading to the lubrication point, will reduce the
    need for the operator or maintenance worker to
    enter the hazardous area.

85
General Safety Guidelines
  • Non-Mechanical Hazards
  • All power sources for machinery
  • Electrical systems safety
  • High pressure systems
  • Inspection and maintenance to prevent pulsation,
    vibration and leaks
  • Excessive noise
  • Engineering controls and hearing protection

86
GSG Non-Mechanical Hazards
  • Excessive vibration
  • Machines must be properly aligned, supported and
    if necessary, anchored
  • Hazardous chemicals
  • Ventilation and proper personal protective
    equipment will help to protect worker

87
General Safety Guidelines
  • Controlling Work Shop Risks
  • Adequate facilities
  • Proper ventilation
  • Non-slip surfaces
  • Hand washing facilities

88
GSG - Controlling Work Shop Risks

92
GSG Controlling Work Shop Risks
  • Knowledgeable workers
  • Experienced
  • Trained

93
GSG Controlling Work Shop Risks
  • All work shop doors should be labeled with
    emergency contact information
  • If an incident occurs during off-hours,
    respondents need to know the names and telephone
    numbers of the people responsible for work shop
    operations
  • Keep this information current and accurate

94
GSG Controlling Work Shop Risks
  • Properly trained and experienced workers have the
    greatest ability to control work shop risks
  • By using good work shop practices, workers can
    minimize hazards, exposure, contamination, and
    workplace accidents

95
General Safety Guidelines
  • Safe Work Shop Practices
  • The following safe work shop practices should be
    developed for each shop as appropriate

Responding to Work Shop Emergencies
  • Dealing with Chemical Spills
  • All faculty, staff and students should be
    prepared to respond to chemical spills in a work
    shop setting
  • Planning ahead and equipping the work shop with
    the required equipment usually ensures a quick,
    safe and effective response

116
RWSE Dealing with Chemical Spills
  • Spill response requires a knowledge of the
    physical, chemical and toxicological properties
    of spilled chemicals
  • When a spill occurs, occupants must immediately
    assess the situation to see if the spill has
    created a serious or even life-threatening
    situation requiring an immediate building
    evacuation

117
RWSE Dealing with Chemical Spills
  • A spill of a few millilitres of a solvent may not
    present a major hazard
  • A spill of an appreciable volume of a flammable
    liquid might call for a building evacuation

118
RWSE Dealing with Chemical Spills
  • Most departments should have spill kits which
    contain absorbents, protective equipment and a
    selection of small tools for use in responding to
    small chemicals spills
  • Information on the location of these spill kits
    and a list of the contents is available from your
    Departmental office

119
RWSE Dealing with Chemical Spills
  • If the spill or leak is significant and there is
    risk of fire, explosion or toxic levels of
    Airborne contamination
  • Immediately evacuate the area, stopping the leak
    only if it is safe to do so
  • Close doors behind you
  • Warn others in the area to evacuate
  • Sound the building alarm
  • Call Security by dialing 80

120
RWSE Dealing with Chemical Spills
  • If you feel confident of your ability to deal
    with the spill and you are sure that you and
    others in the building are not in danger
  • Stop the source of the leak or spill
  • Provide ventilation
  • Extinguish sources of ignition
  • Wear protective equipment including lab coat,
    impervious gloves, safety glasses or goggles,
    face shields, aprons, and shoe covers or
    impervious boots as needed

121
RWSE Dealing with Chemical Spills
  • Contain the spill
  • Neutralize or treat the spill to reduce the
    hazard
  • Collect liquid spills using clay or commercial
    absorbent products
  • Store waste for proper disposal

122
Responding to Work Shop Emergencies
  • First Aid for Chemical or Equipment Exposures
  • The first aid provider should first quickly
    assess the situation to ensure that, in trying to
    help, he or she is not at risk
  • Although many minor injuries can await the
    arrival of medical assistance, some require
    immediate action, such as loss of appendage,
    excessive bleeding, person has stopped breathing,
    splash or spill of chemical
