21. E-WASTE MANAGEMENT
What is e - waste ?
Electronic waste (e-waste) comprises waste electronics/electrical goods that are not
fit for their originally intended use or have reached their end of life. This may include
items such as computers, servers, mainframes, monitors, CDs, printers, scanners,
copiers, calculators, fax machines, battery cells, cellular phones, transceivers, TVs,
medical apparatus and electronic components besides white goods such as
refrigerators and air-conditioners.
When you throwing e-waste into the dustbin, it’s creates problems for the ecology
directly or indirectly for the living beings which are presents in air, water and cause
soil pollution.
E-waste contains materials like copper, silver, gold and platinum which could be
processed for their recovery.
E-waste contains toxic substances and chemicals, which are adverse effect on
environment and health, if not handled properly E - waste is hazardous only if it
contains hazardous constitutents.
22. Stop Growing of
Electronic Waste
Conclusion
• It is important that we create a national framework
for the environmentally sound management of e-
waste including wide public awareness and education
• Conduct detailed inventories of e-waste
• Initiate pilot schemes on collection and sorting of e-
wastes,including take back schemes and schemes for
repair refurbishment and recycling

• Propylene Units
• Polypropylene Units
• Butadiene Units
• Butene Units
• Aromatics Units
24. Personal Protective Equipment (PPE)
Why do you need PPE?
On November 14, 2007, OSHA announced a new rule regarding employers to provide personal
protective equipment (PPE), that is required for any industry because it is safer and cheaper to eliminate
hazards than to provide personal protective equipment.
Protecting Employees from Workplace Hazards
• Employers must protect employees from workplace hazards and dangerous work procedures that can
cause injury, illness and fatalities.
• By Assessment of different physical hazards that may be present in your work area, which includes :
Sources of motion , high and low temperatures , falling objects , sharp objects , rolling objects , electric
hazards , slip and falls , harmful dusts , light radiation , welding , heat treating & high intensity lights etc.
25. Employees must:
Use all feasible engineering and work practice controls to eliminate and reduce hazards
• Then use appropriate PPE if these controls do not eliminate hazards
Training
Employees required to use PPE must be trained to know at least the following
When PPE is necessary
What type of PPE is necessary
How to properly put on, take off, adjust, and wear
Limitations of the PPE
Proper care, maintenance, useful life and disposal
Remember: PPE is the last control steps
Body Part Protection
26. Eye and Face Protection
Thousands of people are blinded every year from work related eye injuries. Which has been prevented,
if only people would have used eye or face protection. Types of eye / face hazards.
• Impact
• Heat
• Chemicals
• Dust
• Light or Radiation
Regular glasses or sunglasses are not appropriate SAFETY GLASSES
Object Striking Eyes
Dusts, Powders, Fumes, Mists , Small particles can enter your eyes & damage them.
Contact with Chemicals

expose your eyes to heat, ultraviolet, and infrared radiation
Control of Hazards
Machine Guards, Ventilation, Lighting , Safe Work Practices , Signs & Warnings , Eyewash Station
27. Goggles , Face Shields , Welding Helmets
90 % of all eye injuries can be prevented by suitable eye protection
Head Protection
Why is Head Protection Important?
In and around your head are : Eyes (with which you see), Ears (you hear), Nose
(you smell), Mouth (you eat and speak), Brain (you think). So injuries to the head
are very serious. For this reason, head protection and safety are very important .
Potential Incidences of Head Hazards
Impact : Falling of hard objects, Injuries include neck, Electric Shock, Drips, Molten
metals can irritate and burn the head, Toxic liquids such as acids, caustics.
Types of Head PPE
Hard hats
28. Hand Protection
Why is Hand Protection Important ?
Human hands are unique. No other creature can grasp, hold, move
and manipulate objects like a human hand. The hand is one of the
most complex parts of your body that coordination between bones,
tissues and nerves allows you to grip and do a variety of complex
tasks. Without your fingers or hands, your ability to work would be
greatly reduced. Almost 20% of all disabling accidents on the job
involve the hands
Types of Hand PPE Gloves
1). Metal mesh gloves – (resist sharp edges and prevent cuts), 2). Leather gloves – (shield your hands
from rough surfaces), 3). Vinyl and neoprene gloves – (protect your hands against toxic chemicals), 4).
Rubber gloves – (protect you when working around electricity), 5). Padded cloth gloves – (protect your
hands from sharp edges, dirt & vibration)
29. 6). Heat resistant gloves – (protect from heat and flames), 7). Latex disposable gloves – (protect from
germs and bacteria), 8). Lead-lined gloves – (protect from radiation sources), 9). Forearm Cuffs, Thumb
Guards, Mittens - (protect from forearm, thumb or fingers, protect your hands while working around very
cold or hot materials)
Foot Protection
Why is Foot Protection Important?
The human foot is rigid enough to support the weight of your entire body, and
yet flexible enough to allow you to run, dance, play sports, and to take you
anywhere you want to go. Without your feet and toes, your ability to work at
your job would be greatly reduced.
30. 1). Impact Injuries – (At work, heavy objects can fall on your feet or any sharp objects), 2). Injuries from
Spills – (hazardous chemical such as acids, caustics, and molten metals which cause and heat burns), 3).
Compression Injuries – (Heavy machinery, equipment, and other objects can roll over your feet which results
broken or crushed bones), 4). Electrical Shocks – (cause severe shocks and burns), 5). Extremes in Cold,
Heat, and Moisture, 6). Slipping – (Oil, water, soaps, wax, and other chemicals can cause you to slip & fall ).
Potential Incidences of Foot Hazards
Types of Foot PPE – ( Shoes & Boots )
1). Steel toe footwear – (protects your toes from falling objects and from being crushed), 2).
Metatarsal footwear – (special guards that run from your ankle to your toes and protect
your entire foot ), 3). Reinforced sole footwear – (metal reinforcement that protects your
foot from punctures), 4). Latex/Rubber footwear – (resists chemicals and provides extra
traction on slippery surfaces), 5). PVC footwear – (protects your feet against moisture and
improves traction)
31. 6). Butyl footwear – (protects against most ketones, aldehydes, alcohols, acids, salts, and alkalies), 7). Vinyl
footwear – (resists solvents, acids, alkalies, salts, water, grease, and blood), 8). Nitrile footwear – (resists
animal fats, oils, and chemicals), 9) Electrical hazard footwear – (insulated rubber to prevent shocks and
burns from electricity), 10). Disposable footwear – (shower slippers, clear polyethylene and non-woven
booties used in dust free work areas like TAJ MAHAL , Agra, India)
