INDUSTRIAL HYGIENE = 0r ≠ OCCUPATIONAL HYGIENE What is Industrial Hygiene? Industrial hygiene is the science of anticipating, recognizing, evaluating, and controlling workplace conditions that may cause workers' injury or illness Berenice I Ferrari Goelzer 9/26/2016 What is Industrial Hygiene? Industrial hygiene : the science of protecting and enhancing the health and safety of pepeole at work and in their communities The American Board of Inductrial Hygiene Key factors: - Employee exposure to hazards - Control for hazards to protect workers Basic principles of Industrial Hygiene Anticipation of potential risks Recognition of existing health hazards at the workplace Evaluation of health risks Contol of unacceptable risks Remember the acronym: A.R.E.C 9/26/2016 Steps to Protect Employees Review products, purchases, projects, tasks, designs, experiments, etc Engineering controls, administrative controls, substitution, personal protective equipment Task planning and hazard analysis of injury/illness, trend analysis, reported concerns Inspections, exposure assessment, modeling, visual assessments, professional judgment Factors affected to industrial hygiene • • • • • • • • • Micro-climate Chemicals Noise Vibration Radiation Light Dust Harmful microorganism Ergonomic 9/26/2016 Factors affected to industrial hygiene • • • • Chemical hazards Physical hazards Biological hazards Ergonomic hazards Environmental Factors or Stresses Chemical hazards • gases, vapors, dusts, fumes, mists, and smoke Physical hazards: radiation, noise, vibration, extreme temperatures and pressures 12 9/26/2016 Environmental Factors or Stresses Hazards 13 Chemical hazards • Dusts, fumes, gases, mists • Skin contact with oils, paints etc 9/26/2016 Physical agents • • • • Noise, Vibration Heat UV Biological hazards • Legionella • Zoonoses • Anthrax Ex: Wastes from hospitals and research facilities containing disease-causing organism s that could infect site personnel 9/26/2016 Ergonomic hazards An ergonomic hazard is a physical factor within the environment that harms the musculoskeletal system • Manual handling • Repetitive work • Display screen equipment Factors affected to industrial hygiene • • • • • • • • • Micro-climate Chemicals Noise Vibration Radiation Light Dust Harmful microorganism Ergonomic 9/26/2016 What is microclimate? Meteorology: A microclimate is the distinctive climate of a smallscale area, such as a garden, park, valley or part of a city The weather variables in a microclimate, such as temperature, rainfall, wind or humidity, may be subtly different to the condition prevailing over the area as a whole and from those that might be reasonably expected under certain types of pressure or cloud cover What is microclimate? Occupational Hygiene: Microclimate is the physical state of the atmosphere in the narrow space of the workplace including the factors temperature, humidity, radiant heat and speed of air transport These factors must be guaranteed in certain limit, consistent with human physiology 10 ...9 /26 /20 16 Industrial/ Occupational Hygiene?
