Title: Industrial Hygiene


1
Industrial Hygiene
2
Industrial Hygiene
  • A specialization in the broad field of safety and
    health.

3
OSHAct and Industrial Hygiene
  • Use Warning Labels
  • Use proper PPEs
  • Provision of medical tests
  • Maintain accurate records
  • Accessibility Availability of tests
    monitoring to employees
  • Notification of employees who have been exposed
    to environmental stressors

4
OSHA Process Safety
  • Coverage
  • Employee Participation
  • Process Safety Information
  • Process Hazard Analysis
  • Standard Operating Procedures
  • Requirements for Contractors

5
MSDS Sheets
  • General Information
  • Hazardous Ingredients
  • Physical Chemical Characteristics
  • Fire Explosive Hazard Data
  • Health Hazards
  • Safe Handling and Use
  • Control Measures

6
Points of Entry
  • Inhalation
  • Absorption
  • Ingestion
  • Injection

7
Effects
  • Acute
  • Sudden dose, high concentrations
  • Chronic
  • Gradual dose over a period of time

8
Airborne Contaminants
  • Dusts
  • Fumes
  • Smoke
  • Aerosols
  • Mists
  • Gases
  • Vapors

9
Effects of Airborne Contaminants
  • Irritants
  • Irritation to the skin, eyes, nose, mouth,
    throat, and upper respiratory tract
  • Asphyxiants
  • Disrupt breathing so severely that suffocation
    results
  • Narcotics

10
Common Industrial Hygiene Problems
  • Asbestos
  • Sick Building Syndrome
  • Explosive Hazards
  • Confined Space

11
Exposure Thresholds
  • Time Weighted Average (TWA)
  • Short-term Exposure Limit
  • Exposure Ceiling

12
Recognizing Hazards
  • What is produced?
  • What raw materials are used?
  • What additional materials are used in the
    process?
  • What equipment is used?
  • What operational procedures are involved?

13
Recognizing Hazards
  • What dust control procedures are involved?
  • How are accidental spills cleaned up?
  • How are waste by-products disposed?
  • Is there adequate ventilation?
  • Are the processes equipped with exhaust devices?

14
Recognizing Hazards
  • How does the facility layout contribute to
    employee exposure?
  • Are properly working PPEs available?
  • Are safe operating procedures recorded, made
    available, monitored and enforced?

15
Control
  • Engineering Controls
  • Ventilation
  • PPEs
  • Administrative Controls
  • Additional Strategies

16
Important Laws
  • OSHA Chemical Process Standard
  • EPA Clean Air Act
  • SARA
  • Hazardous Materials Transportation Uniform
    Safety Act.

17
Confined Space Standard
  • Shutdown Equipment/Power
  • Test Atmosphere
  • Ventilate the Space
  • Have Rescue Personnel Stand By
  • Maintain Communication
  • Use a Lifeline

18
Industrial SafetyIT 335
  • Chapter 16
  • Noise and Vibration Hazards

19
Characteristics
  • Noise
  • Unwanted sound
  • Decibel
  • Measurement of sound
  • Threshold of Hearing
  • Sounds heard by the human ear
  • Threshold of pain
  • Max level of sound without experiencing pain

20
Hearing Loss Factors
  • Intensity of the Noise
  • Type of Noise
  • Daily Duration of Exposure
  • Total Duration of Exposure
  • Individuals age
  • Coexisting hearing problems
  • Nature of the Environment
  • Distance from the source
  • Position of the ears relative to the sound source

21
Critical Noise Risk Factors
  • Noise Level
  • Frequency
  • Duration
  • Distribution

22
OSHA Regulations
  • Monitoring Noise Levels
  • Medical Surveillance
  • Noise Controls
  • Personal Protection
  • Education Training

23
Workers Comp. Hearing Loss
  • Onset and Progress of the employees history of
    hearing loss
  • The employees complete work history
  • Results of a hearing exam
  • Results of hearing studies
  • Determination of whether the loss originated from
    outside the workplace

24
Identifying Noise Hazards
  • Noise Surveys
  • Audiometric Testing
  • Record Keeping
  • Follow-Up

25
Noise Controls
  • Engineering Controls (pg 378-379)
  • Administrative Controls (pg 380)
  • Hearing protection (pg 380)

26
PreventingVibration Hazards
  • Low Vibration tools
  • Limit Employee Exposure
  • Change Employee Work Habits
