Industrial Hygiene A specialization in the broad field of safety and health.
OSHAct and Industrial Hygiene • Use Warning Labels • Use proper PPE’s • Provision of medical tests • Maintain accurate records • Accessibility & Availability of tests & monitoring to employees • Notification of employees who have been exposed to environmental stressors
OSHA Process Safety • Coverage • Employee Participation • Process Safety Information • Process Hazard Analysis • Standard Operating Procedures • Requirements for Contractors
MSDS Sheets • General Information • Hazardous Ingredients • Physical & Chemical Characteristics • Fire & Explosive Hazard Data • Health Hazards • Safe Handling and Use • Control Measures
Points of Entry • Inhalation • Absorption • Ingestion • Injection
Effects • Acute • Sudden dose, high concentrations • Chronic • Gradual dose over a period of time
Airborne Contaminants • Dusts • Fumes • Smoke • Aerosols • Mists • Gases • Vapors
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
Common Industrial Hygiene Problems • Asbestos • Sick Building Syndrome • Explosive Hazards • Confined Space
Exposure Thresholds • Time Weighted Average (TWA) • Short-term Exposure Limit • Exposure Ceiling
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?
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?
Recognizing Hazards • How does the facility layout contribute to employee exposure? • Are properly working PPE’s available? • Are safe operating procedures recorded, made available, monitored and enforced?
Control • Engineering Controls • Ventilation • PPE’s • Administrative Controls • Additional Strategies
Important Laws • OSHA Chemical Process Standard • EPA Clean Air Act • SARA • Hazardous Materials Transportation & Uniform Safety Act.
Confined Space Standard • Shutdown Equipment/Power • Test Atmosphere • Ventilate the Space • Have Rescue Personnel Stand By • Maintain Communication • Use a Lifeline
Industrial SafetyIT 335 Chapter 16 Noise and Vibration Hazards
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
Intensity of the Noise Type of Noise Daily Duration of Exposure Total Duration of Exposure Individual’s age Coexisting hearing problems Nature of the Environment Distance from the source Position of the ears relative to the sound source Hearing Loss Factors
Critical Noise Risk Factors • Noise Level • Frequency • Duration • Distribution
OSHA Regulations • Monitoring Noise Levels • Medical Surveillance • Noise Controls • Personal Protection • Education & Training
Workers’ Comp.& Hearing Loss • Onset and Progress of the employee’s 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
Identifying Noise Hazards • Noise Surveys • Audiometric Testing • Record Keeping • Follow-Up
Noise Controls • Engineering Controls (pg 378-379) • Administrative Controls (pg 380) • Hearing protection (pg 380)
PreventingVibration Hazards • Low Vibration tools • Limit Employee Exposure • Change Employee Work Habits
