Accident

• An employee of Majestic Marble was laying tile on
  the fifth floor when he walked in to a nearby
  room he fell between 35 and 40 ft down landing on
  metal ducting. He sustained a broken toe, a
  puncture wound to his left shin, he cut open his
  forehead and multiple abrasions

4
What was the Cause

• The room was improperly lit
• The worker did not have the required head lamp or
  flash light

5
Why is it Important?

• Increases Productivity
• Enhances Comfort
• Most importantly improves safety

6
Common Misconception

• People often think lighting is only a problem if
  it is too dark but lights that are too bright can
  also be dangerous
• Having to work in awkward positions because light
  is in your eyes can cause eyestrain and headaches
  making anything you are working on more dangerous

7
Temporary Lighting

• Extension Cords/ String Lighting
• Head Lamps/ Flash lights

8
Extension Cord/ String Lighting

• Extension cord with light bulbs attached at set
  intervals
• Each bulb must be covered with a plastic cage to
  protect bulbs from breaking
• Very important to be strung properly

9
Flash Lights/ Head Lamp

• This method is best when working in confined
  spaces
• Head lamps are better because leaves hands free

10
The Unit of Measurement

• Lighting is measured in foot candles
• One foot candle is the amount of light given off
  by one candle one foot away
• A Light meter is used to measure the number of
  foot candles

Example 3

15
Emergency Lighting

• Emergency illumination must be provided for a
  minimum of 1.5 hours in the event of failure of
  normal lighting.
• Must provide initial illumination of on average
  at least one foot-candle and a minimum at any
  point of 0.1 foot-candle measured along the path
  of egress at floor level.
• The maximum illumination at any one point can be
  no more than 40 times the minimum illumination at
  any one point to prevent excessively bright and
  dark spots

• Lighting is often a neglected part of jobsite
  safety and is the cause of many fall incidents
• Safety accidents can be reduced simply by
  following the lighting safety regulations
