Industrial Lighting importance in industry

2. Accidents take place due to unsafe acts and
unsafe conditions. One of major unsafe
conditions is inadequate and bad lighting

3. Creating a good industrial lighting system
involves considering numerous design criteria
while considering the visual tasks involved and
operating conditions.

4.  Determine the quality of illumination needed for
particular manufacturing process.
 Determine the quantity of illumination required
at the task/process
 Determine the appropriate lighting level required
for safety and ensure all three of the factors
which are quality, quantity and safety
 Select the listed/approved lighting equipment
that satisfies all requirements including
mechanical performance.
 Prepare a lighting fixture layout that responds to
the concerns of safety and maintenance
 Review the energy, economic and operating
characteristics of lighting system

5.  To make detailed observation of all types of
unsafe physical and environmental condition,
as well as unsafe physical throughout the
plants.
 While making these observation the
supervisor should accompany the surveyor to
note down
 These observations are noted down in tabular
form and the remedial measures are
suggested against each unsafe condition,
unsafe action and unsafe work practices

6.  In every part of factory, sufficient and
suitable lighting should be provided
 In every factory all glazed windows and
skylights used for lighting of inner and outer
surface shall be kept clean.
 In every part of factory, provision shall be
made for the prevention of:
1. Glare
2. Shadow

7. Place in Industry Level of illumination (in Lux)
Canteen 150
Cloak Room 100
Entries, Corridors, Stairs etc. 100
Assembly Shop and Rough Work 150
Medium Work 300
Fine Work 700
Very Fine Work 1500

8. The level of illumination required in a work
room of factory depends on other factors such
as:
 Age of workers: below 40 years can work in
half and one-third of average illumination
and above 40 years 2 to 5 times of average
illumination
 Size of object
 Contrast between object and background
 Glare arises when some part of field is bright

9.  Fluorescent lamps and tubes give more light than
incandescent lamps for same electrical energy
consumed
 To avoid glare, light source should be as high as
possible
 The fittings should be designed according to the type
of work involved in the work room
 The walls of work room and ceiling should be painted
with light colour because it does not cause eye strain
 A balanced combination of natural and artificial
lighting can be made available
 To maintain good lighting, the windows, sky lamps,
lamps and all light shades should be kept clean

10. Under the Factory Act 1948, following are the
provisions to be made regarding ventilation and
temperature:
 Adequate ventilation by circulation of fresh air
 Comfort temperature should be provide to
workers to prevent injury to their health
 Walls and rooms shall be of material so it would
not exceed temperature beyond the limit
 If temperature is high then separating of that
work place to others should be done

11.  In any factory, maximum temperature of air
in work room at a height of 1.5 m above floor
level shall not exceed 30ºC and adequate
movement of atleast 30mpm shall be
provided
 In every factory, the amount of fresh air
supplied by mechanical means of ventilation
in an hour shall be equivalent to at least 6
times cubic capacity of workroom and it shall
be evenly distributed to work room without
dead air pocket

12. Ventilation is an engineering that control
measure or technique practiced to improve the
quality of air in the work area

13.  Either to cool/heat the work area according to
requirement
 To remove the contaminant from the
atmosphere of work room
 If removal of contaminant is not possible,
dilute the concentration of the contaminant in
atmosphere of work room
 Supply of additionally required air in the
working area

14.  Ventilation helps to reduce the concentration
level of explosive and thus avoids the
chances of explosion
 As ventilation helps to reduce the harmful
contaminants from the atmosphere of work
room, the health of the workers is protected
from occupational diseases
 Ventilation provides comfort to the workmen
and hence efficiency of workmen improves
