6 Integrate Industrial Hygiene Into Your EHS System Engineering Quality Data management Product life cycle Training Compliance Hazard tracking system Management commitment Hazard Assessment Techniques Job Hazard Analysis JHA Fault Tree Analysis FTA Energy trace barrier analysis ETBA Preliminary Hazard Assessment PHA Management Oversight Risk Tree MORT Failure Mode Effect Analysis FMEA

7 Accident Causation Operational Behavioral Cultural Product or Process Life Cycle (Slates, 2011). Concepts design Wear out Operational

8 Closed Loop Hazard Tracking System (Slates, 2011) Hazard Identification Communicate to Employees Hazard Control Reevaluate Control Effectiveness Regulatory Agencies & Organizations 1. OSHA Act American Conference of governmental Industrial Hygienists OSHA promulgates and enforces regulations 4. NIOSH conducts research 5. OSHRC adjudicate and interprets regulations 6. General Duty Clause 5 (a) 1.

9 Many OSHA standards were adopted from National Consensus Standards ANSI ACGIH NFPA Occupational Exposure limits OSHA permissible exposure limits PELs were adopted from ACGIH 1968 TLVs ACGIH TVLs and OSHA PELs are based on 8 hr day 40 hour week Short term exposure 15 minutes Ceiling level instantaneous exposure measurement

10 Air Contaminates & Toxic Substances 29 CFR Asbestos Lead Benzene Carbon monoxide Cadmium Hexavalent chrome Acetone Formaldehyde 8 TWA Calculation Two hours exposure at 150 ppm Two hours exposure at 75 ppm Four hours exposure at 50 ppm Substituting this information in the formula, we have ( ) 8 = ppm Since ppm is less than 100 ppm, the 8-hour time weighted average limit, the exposure is acceptable.

11 Exposure Limits Considerations Are OSHA exposure limits updated annually? Will OSHA exposure limits protect 100% of the working population exposed? ACGIH TLVs are updated annually Exposure limits do not take into account the synergetic effects of the exposure to multiple chemicals Understanding human health Why is it important to have a basic understanding of the various components of the human anatomy? Usually the industrial hygienist is concerned with the evaluation of the problem from the heath perspective.

12 Health Related Standards Noise and hearing conservation Process safety management Bloodborne pathogens Respiratory protection Laboratory safety Indoor air quality Personal protective equipment Ergonomics Confined space Flammable and combustible substances Types of Air Contaminates Fume Mists Vapor Dust Smoke gases

13 Routes of entry What are the 3 major routes of employee exposure? 1. Inhalation 2. Absorption 3. Ingestion Globally Harmonized System Revision of the current hazard communication standard 29 CFR Should improve comprehensibility and facilitate compliance

14 Major Change in Approach Labeling provisions are the biggest difference between HCS and GHS Specific approach will require all labels to be modified to comply GHS Workshop, 10/20/2006 Safety Data Sheets HCS allows any order of information Consistent with industry approaches in ANSI and ISO Should improve comprehensibility and help with issues regarding accuracy of the information GHS Workshop, 10/20/2006

15 Hazard Warning Labels: HMIS & NFPA Dose Response Curve

16 Health Effects 1. Acute 2. Sub chronic 3. Chronic Organs 1. The respiratory system 2. The skin 3. The ear Inhalation Health Hazards Welding fumes Asbestosis Biological Benzene Coal dust solvent vapors Formaldehyde Carbon monoxide Lead Arsenic Lung disease Silicosis Asbestosis Metal fume fever Bronchitis Asthma Emphysema Cancer

17 Major section of the Lungs 1. Nasal pharyngeal 2. Bronchial 3. Pulmonary alveoli The Ear Decibel 90 dba PEL 85 dba Action level

18 Noise Evaluation Methods 1. Sound level meter 2. Dosimeter 3. Octave band analyzer Understanding radiation Radiation is a form of energy All forms of radiation exist as a phenomenon known as electromagnetic spectrum Please note that the shorter the wavelength the more ionizing the radiation becomes

19 Radiation Radiation is a means of propagating energy. Type types Ionizing radiation > 10 electron volts Non ionization radiation Lasers Alpha Beta X rays Control Distance Shielding Radio active decay (time)

20 Bloodborne pathogens standard Engineering controls 2. Work practices controls 3. PPE 4. Labeling requirements 5. Employee training and education 6. Needle stick prevention PPE General Requirements Personal protective equipment PPE hazard assessment Eyes Face Hand PPE certification

21 What is Meant by the Term Permeation Rate? Permeation rate is the rate at which the chemical will move through the material As a rule of thumb, the denser the materials the lower the dexterity. 15% of the population is allergic to latex

22 Lab Hazards Flammable and combustibles Toxic and hazardous substances Heavy metals VOCs Fire prevention Explosions Spill prevention Fume hood capture velocities Emergency action plan Chemical storage PPE Compressed gas cylinders Chemical Hygiene Plan More than 500,000 workers are employed in laboratories in the U.S. The laboratory environment can be a hazardous place to work. Laboratory workers are exposed to numerous potential hazards including chemical, biological, physical and radioactive hazards, as well as musculoskeletal stresses.

23 Personal Air Monitoring Carcinogens Mutagens Teratogens Chemical standards Do Quality Control Labs Have to Comply with the CHP? Laboratories that conduct research and development and related analytical work are subject to the requirements of the Laboratory Standard

24 What is a Laboratory Laboratory means a facility where the "laboratory use of hazardous chemicals" occurs. It is a workplace where relatively small quantities of hazardous chemicals are used on a nonproduction basis What is a CHP The CHP is a written program stating the policies, procedures and responsibilities that protect workers from the health hazards associated with the hazardous chemicals used in that particular workplace

25 How often should employers review and evaluate the effectiveness of the CHP? Written Policies and Procedures 1. Use of containment devices such as fume hoods. 2. Procedures for removal of contaminated waste. 3. Decontamination procedures. 4. Spill prevention procedures

26 Who Often Should Showers be Tested? Although the term "routine" does not indicate a specific frequency, it does mean that the inspections should be performed at regular intervals which are determined by someone familiar with the equipment and the work environment. Respiratory protection Types of respirators air purifying and air supplying Major elements of a respiratory program Program administrator Initial monitoring Medical evaluation Respiratory selection Fit testing Care, maintenance and use Training Program evaluation

27 Fume Hood Safety A laboratory fume hood is a three-sided enclosure with an adjustable front opening. It is designed to capture, contain, and exhaust hazardous fumes generated inside its enclosure. ANSI NFPA ACGIH ASHRAE

28 Fume Hood Requirements A laboratory fume hood is a three-sided enclosure with an adjustable front opening. Inspection Filters, negative pressure ASHRAE ANSI Z Sect 5 It is designed to capture, contain, and Air velocity at the hood exhaust hazardous face must average fumes generated inside 120 linear feet per minute its enclosure. Sampling Methodology Chemical exposure limits Chemical or substance health effects Analytical methods OSHA and NIOSH sampling methodologies Media Air sampling equipment Flow rates and volumes

29 Air Sampling and Monitoring 3 Types of Sampling 1. Short term: hand held sampling pumps, direct reading instruments, and colorimetric tubes 2. Long term: personal sampling pumps, long term, tubes and filters 3. Passive samplers: indicator badges

30 Short Term Sampling Used to establish a short term or snap shot assessment of the level of air contamination at the time the sample was taken. Measures contamination levels only at the time and location they were taken and do no provide a comprehensive analysis of the true exposure risk for the overall environment. Long Term Sampling Continuous long term sampling can be conducted using portable battery operated sampling pumps. Sampling pumps draw air thru sampling media at a continuous rate for a set period of time that may be eight hours or more.

31 Long Term Sampling Once the sampling is complete the collected sample can be examined under laboratory conditions. The laboratory will analyze the trapped material on the media and determine concentration and employee exposure can be calculated based on an 8 hour work shift. Passive Sampling 3. Passive samplers: indicator badges are worn by employees in the work area. These badges, known as passive samplers, either change color on exposure to a particular substance or can be subsequently analyzed in a laboratory. Accuracy + 25% Diffusion

32 Challenges & Recommendations What role does organizational safety culture play Nano technology Research funding sources Accountability Written protocols Document and conduct formal training Document and communicate near misses Do not relay on chemical manufactures recommendations. Make site specific requirements for the use of chemicals Thank You! Thank you for participating in the Understanding Industrial Hygiene 101 Webinar.
