Recap Day 1: Key Concepts Identify hazards early. Control hazards using “hierarchy of controls.” Use all information to learn about potential hazards: site history knowledge about industry and processes safety information sheets interviews, site walkthrough, testing Identifying hazards is not enough: they must be controlled effectively.

Day 2 Objectives Understand: route of exposure, dose/response. Demonstrate knowledge of basic occupational airborne standards and guidelines, and how they are measured. Explain the role of personal protective equipment & its limitations. Understand best practices within Occupational Health Nursing Perform Practicum 2

What affects exposure? Route (skin, oral, inhalation) Amount (dose) May 7, 2018 What affects exposure? Route (skin, oral, inhalation) Amount (dose) Duration To whom (animals, humans, environment) Sensitivity (e.g., children) A Small Dose of Toxicology - Overview

Routes of Exposure Inhalation Skin Contact Skin Absorption Ingestion Injection

Hazard Categories Chemical Hazards Physical Hazards Dusts, fumes, Gases, Vapors Physical Hazards Noise – Radiation – Vibration – Ergonomics-

Other Hazards Biological Hazards Insects, mites Bacteria Molds, fungi Plants Animals Ergonomic Stressors Body posture Repetitive motion Fatigue Shift work Lifting

Health Effects or Endpoints: May 7, 2018 Health Effects or Endpoints: Cancer & genetic changes Immune function changes Birth defects & developmental affects Changes in reproductive function Nervous system affects Organ-specific effects A Small Dose of Toxicology - Overview 7

May 7, 2018 The Dose-Response Relationship: How much exposure to a chemical or agent will cause what effect? Response ED50 Threshold (NOAEL) Dose A Small Dose of Toxicology - Overview

Signs that a workplace problem may exist: Employee complains or concerns Introduction of a new chemical Unexplained odors present Accidents or illness reported (test results) Toxic materials used in process Processes which may produce exposures Hazardous chemicals in use

Air Contaminants Dust: solid mechanically produced particles. Fume: condensate of volatized solid. Spray: liquid mechanically produced particle Mist: liquid condensation particle. Vapor: gaseous phase of liquid. Gas: gas at standard temperature and pressure. Why does it matter?

Measuring Workplace Exposures                                                        Biological Samples – blood; urine; hair; exhaled breath

Air Sampling

Potentially Hazardous Processes Combustion noise, products of combustion Heating noise, heating effects Metal melting fumes or dust Electric discharge ozone, nitrogen oxides Dry crushing, grinding dust, noise Mixing, conveying dust, vapors, noise Coating, painting solvents, pigments Electroplating acid mist

Potentially Hazardous Processes Cold or hot forming lubricant, mist, noise Welding, soldering metal, flux, gases Warehousing vehicle emissions Wet mixing mist, dust, noise Hazardous Waste Ops. dust, gases, noise Discuss odor threshold

Worksite Walkthrough Reminders Observe the process closely Interview the people What do they do? How do they do it? What do they use? How much? Evaluate chemical inventory. What personal protective equipment and workplace controls are in place? Do they appear to be effective?

What to look for. . . Visible contaminants Sensory irritation How are work practices? Personal protective equipment in use? Housekeeping & storage Ventilation systems (general & local exhaust) Skin contact with chemicals Sources of additional information? Exposure assessment?

An Industrial Hygienist’s Toolkit Occupational Exposure Limits Type of Sampling 8-hour Time Weighted Averages (TWA) Short-term Exposure Limits (STEL) Ceiling Limits (C) Excursion Limits Personal exposure monitoring Area or process emissions. Continuous or integrated. Grab or instantaneous “Worst exposure”

Measuring Workplace Exposures                                                        Biological Samples – blood; urine; hair; exhaled breath

Occupational Noise Exposure It is estimated that 16% of workers experience hearing loss as a result of excessive noise exposure.

Health Effects Related to Noise Exposure Occupational noise can cause: Psychological stress and fatigue Interference with concentration and communication which may result in: Reduced productivity Higher risk for injury in the workplace Permanent hearing loss

Noise Standards in Thailand Promulgated by the Ministry of Industry and the Ministry of Labour Permissible exposure level is 90 dBA per 8 hour period Hearing Conservation program required if noise is greater than 85dBA

Preventing Noise-Induced Hearing Loss: Hierarchy of Control Engineering controls, i.e., modify or replace equipment, choose low noise tools, isolate noise source Administrative Controls, i.e., limit exposure time, distance from noisy equipment Personal Protection: Hearing protection devices

2005 OHN Certification Review Course Control Engineering controls Substitution; elimination; process change Isolation; enclosure; distance Ventilation Administrative controls Rotation Shift adjustment Housekeeping Education & training Personal Protective Equipment Protective clothing Respirators 2005 OHN Certification Review Course

Practicum 2: Review Safety Data Sheet What is the state(s) or form(s) of the chemical during use? What are the adverse health effects related to overexposure to this chemical? What are some of the airborne occupational exposure limits? (Make sure you know how to explain this) Should someone working with this product wear any type of PPE? How might we best control or reduce exposure to this product?

Practicum 3: Exposure Scenario

Day 2: Key Concepts In order to assess chemical, biological and health exposures, they must be identified and evaluated. Safety data sheets, and other chemical information are useful to better understand hazards related to chemicals, and how to reduce exposures. Reducing exposure through controls (including elimination and substitution) are critical to improving workplace health.
