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

• Prompt response to a fire is the key to
  preventing injury and property damage
• The primary consideration is to prevent injury

113
RWSE Responding to a Fire

• Ryersons Procedure If You Discover a Fire
• Exercise good judgment in deciding whether to
  attempt to extinguish the fire or not, withthe
  fire protection equipment available.
• If in doubt, leave the fire scene, close all
  doors, and activate the nearest pullbox.
• Call Security by dialing 80 from a safe location,
  and give all the pertinent facts.

114
RWSE Responding to a Fire

• Ryersons Procedure If You Discover a Fire
• Leave the building by the nearest safe exit.
• Do not use elevators.
• Stand outside the building to direct the Fire
  Department and/or Security to the exact location
  of the fire.
• You should be familiar with the evacuation policy
  (www.ryerson.ca/cehsm/policies)

115
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

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
