Hazard ControlAN INTRODUCTION

• Hazardous waste sites pose safety and health
  concerns which could result in serious injury or
  death.

4
Hazard ControlAN INTRODUCTION

• Additional hazards are created by
• Heavy equipment
• PPE reducing movement, hearing, and vision
• Unpredictability of the site.

5
Safety hazards that may exist at hazardous waste
sites.

• Holes or ditches.
• Objects that may fall.
• Sharp objects.

6
Safety hazards that may exist at hazardous waste
sites.

• Slippery surfaces.
• Steep grades.
• Uneven terrain.
• Unstable surfaces.

7
What are the electrical hazards that can pose a
danger to workers?

• Overhead power lines.
• Fallen electrical wires.
• Buried cables.
• Electrical equipment (use low-voltage equipment
  with ground-fault interrupters and watertight,
  corrosion-resistant, connecting cables).

8
What are the electrical hazards that can pose a
danger to workers?

• Lighting.
• Weather conditions.
• Capacitors that retain a charge.

9
How do lockout/tagout procedures protect
employees from electrical hazards?

• Before servicing and maintenance of power
  equipment or machines, OSHA regulations require
  lockout/tagout procedures.

10
How do lockout/tagout procedures protect
employees from electrical hazards?

• Lockout device (lock, chain, valve, etc.)
• Prevents flow of energy from a power source to
  power equipment to keep it from operating.

11
How do lockout/tagout procedures protect
employees from electrical hazards?

• Tagout
• Tag the power source acts as a warning, not a
  physical restraint.

12
What is the employers responsibility regarding
lockout/tagout procedures?

• Establish a program.
• Utilize procedures for affixing appropriate
  lockout/tagout devices to power sources.
• Otherwise disable equipment/machine to prevent
  unexpected start-up or release
  of stored energy.

13
Lockout/Tagout Program

• Program must include
• Lockout/Tagout Procedures
• Employee Training
• Periodic Inspections.

14
What effects can noise have on the worker?

• Noise Unwanted Sound.
• Work around large equipment often creates
  excessive noise.
• Effects can vary.

15
What effects can noise have on the worker?

• Workers being startled, annoyed, or districted.
• Physical damage to ear (pain, temporary and/or
  permanent hearing loss).
• Fatigue.
• Elevated blood pressure.
• Tension and nervousness.
• Communication problems.

16
What effects can noise have on the worker?

• The effects of noise depend on
• The length of exposure
• How loud the sound is.

17
What is the unit used to measure sound?

• Sound intensity decibels (dB).
• For example
• Ticking watch 20 dB (barely audible).
• Jet engine 130 to 160 dB (painful).

18
When must an employer begin a Hearing
Conservation Program?

• OSHA Hearing Conservation Standard requires
• A continuing, effective program whenever noise
  levels equal or exceed an 8-hour time-weighted
  average (TWA) sound level of 85 dB,

19
When must an employer begin a Hearing
Conservation Program?

• Administrative or engineering controls must be
  used if workers are subject to noise exceeding an
  8-hour TWA sound level of 90 dB, then

20
What can be done to minimize workerexposure to
noise?

• Noise monitoring.
• Audiometeric testing.
• Engineering controls (sound-absorbing rooms,
  substitution, carpet, resilient floors/pads,
  sound-dampening walls).

21
What can be done to minimize workerexposure to
noise?

• Administrative controls (rotate employees,
  operate noisy machinery on shifts with fewer
  employees).
• PPE (earplugs, earmuffs).
• Training.

22
When is eye and face protection required?

• Reasonable probability of injury from
• Flying objects
• Glare
• Liquids
• Injurious radiation
• Combination of the above hazards.

23
When is eye and face protection required?

• When projectiles are a potential hazard, workers
  must use eye protection that provides side
  protection.

24
What are the requirements of eye and face PPEs?

• Must be
• Distinctly marked to facilitate identification of
  the manufacturer
• Capable of being disinfected and easily
  cleaned.

25
What are the requirements for prescription and
contact lens wearers?

• Prescription lens wearers need
• Eye protection incorporating the prescription in
  its design
• Or eye protection worn over the
  prescription lenses without disturbing
  the proper position of either.

26
What are the requirements for prescription and
contact lens wearers?

• The use of contact lenses should
• Be considered carefully
• Comply with the site-specific HASP.

27
Describe the correct way to use the eye-wash
water solutions.

• When chemical hazards are present
• Eye wash stations - readily available and
  accessible
• Water/eye solutions - aimed at base of nose to
  prevent particles from being driven into the
  eyes further.

28
When must head protection be worn?

• Where potential hazards are present from
• Impact and penetration of falling/flying objects
• Limited electric shock/burn.

29
When must head protection be worn?

• Head protection must meet all safety
  requirements.
• Caps, elastic bands, or hairnets- prevent hair
  from contacting instruments, machinery parts, or
  flame-producing sources.
• Fabric hats (baseball caps) should not be worn
  where contaminant can be absorbed.

30
When is protective footwear required?

• Where potential hazards are present from
• Falling or rolling objects.
• Objects piercing the sole.
• Corrosive chemicals.
• Electrical shock.
• Wet floors.

31
What are the recommended types of footwear?

• Safety toe shoes (steel-toe).
• Treated shoes.
• Rubber boots or plastic shoe covers.
• Insulated shoes.
• Rubber boots with wooden soles.

32
When is hand protection required?

• When there are hazards from
• Skin absorption
• Cuts, abrasions, punctures
• Chemical or thermal burns
• Harmful temperature extremes.

33
When is hand protection required?

• Employers must require employees to use
  appropriate hand protection that meets all safety
  requirements.

34
When is hand protection required?

• Select gloves on the basis of
• Material being handled
• Hazard involved.

35
When is hand protection required?

• Check before using
• In good condition
• Free from holes, punctures, or tears.
• When removing
• Keep contaminated surface from contacting skin.
